Introduction   

Chemotherapy is a foundational cancer treatment that can play a crucial role in managing various cancer diagnoses. While the benefit of administering chemotherapy is evident, it comes with unique challenges and risks. As a nurse caring for patients receiving chemotherapy, it is necessary to understand safe practices to protect the patient and healthcare providers simultaneously. Understanding how to equip patients and providers when administering chemotherapy ensures the benefits outweigh the challenges that come with exposure to chemotherapy drugs (1). 

When providing chemotherapy, there are certain risks associated with such treatments. The patient may experience adverse reactions, complications, or environmental hazards associated with cytotoxic agents. Safe administration begins with the nurse, protecting patients from unnecessary harm. These safe practices also reduce the likelihood of complications associated with incorrect dosing, monitoring, or handling of chemotherapy agents (1). 

To properly administer chemotherapy safely, the healthcare professional must have a thorough understanding of safe chemotherapy administration practices and guidelines. To accomplish this, the nurse must be prepared to conduct patient assessments, observe for potential side effects, and practice safe handling protocols. Through proper education and practice, nurses can reduce the risks associated with chemotherapy, enhance patient outcomes, and promote a culture of safety in the workplace (1). 

Definition 

Chemotherapy is a treatment modality used to kill or inhibit the growth of cancer cells. These drugs target rapidly dividing cells. Chemotherapy is most commonly associated with cancer treatment but can be used for other diagnoses such as autoimmune disease. The goal of chemotherapy varies depending on the clinical diagnosis, but it is commonly used as a primary treatment or as an adjunct to other treatment types (2) 

Three treatment types fall under the umbrella of chemotherapy. Traditional chemotherapy is a treatment type that involves the use of cytotoxic drugs to target rapidly dividing cells, both cancerous and non-cancerous. These chemotherapy treatments may include alkylating agents, antimetabolites, and topoisomerase inhibitors. The effectiveness of chemotherapy drugs will be dependent on the tumor size and may impact other body systems, including bone marrow and the digestive tract (2). 

Next, targeted therapy is another treatment option. This focused on specific molecular targets that are associated with cancer. This treatment type is designed to interfere with specific pathways or mutations that contribute to cancer cell growth and survival. These may include tyrosine kinase inhibitors and monoclonal antibodies. Targeted therapies often result in fewer side effects compared to traditional chemotherapy because they are less likely to impact healthy cells (2). 

Immunotherapy is the third and final therapy to review. Immunotherapy utilizes the body’s natural immune defenses to fight off cancer. Immunotherapy takes various forms, including checkpoint inhibitors, CAR T-cell therapy, and cytokine therapy. These items enhance the immune system’s response to cancer cells ultimately seeking out and destroying the cells. Because of this approach, immunotherapy is a promising treatment for various cancer types when other treatments have failed (3). 

Differences Between Curative and Palliative Chemotherapy 

There are two primary focuses when providing chemotherapy: either curative or palliative. Curative chemotherapy refers to providing chemotherapy in hopes of eliminating cancer – or curing the patient of the cancer they are diagnosed with. Curative treatment is typically reserved for cancer that is localized or has not metastasized significantly. These treatments typically are aggressive in hopes of eradicating all cancer cells and leading to remission. This approach can be successful for many patients, ultimately leading to a cure and improving the survival rates and overall quality of life for patients (4). 

Conversely, palliate chemotherapy focuses more on alleviating symptoms and improving the quality of life for patients who are experiencing advanced or metastatic cancer. The goal here is not to cure but rather to manage the tumor burden, reducing or managing symptoms experienced, and prolonging the overall survival for as long as possible. Palliative chemotherapy is dosed at lower or less aggressive ranges to reduce the side effects associated with chemotherapy regimens. This reduction aims to improve the quality of life while the chemotherapy treatments aim to prolong the number of days, months, or years the patient has left despite their terminal diagnosis (4).  

By understanding this significant difference, both patients and their support systems can make appropriate decisions surrounding their preferred treatment type. Each approach has benefits and drawbacks, and the patient should be properly educated surrounding the potential for each in the patient’s treatment plan. Personalizing the patient’s treatment plan to not only their diagnosis and stage of cancer, but their unique barriers to care, co-morbidities, and other unique challenges that are present in their day-to-day life, allows for greater adherence to the treatment plan, and ultimately better patient outcomes. 

Assessment 

The cancer patient will need to be assessed at various times throughout their cancer care journey. Depending on the phase of which they are in, the assessment will be different. When referring to providing chemotherapy, there are a few different assessment types. First, a pre-administration assessment of patients must occur. This assessment ensures the patient is safe to receive chemotherapy administration. This process involves gathering comprehensive information regarding the patient’s medical history, current health status, and specific risk factors that impact the treatment outcomes (5). 

The patient’s medical history should include all previous cancer treatments, comorbidities, allergies, and any history of adverse reactions to the medications. Understanding the patient’s current health status helps determine if a patient can receive chemotherapy and adjust treatments as needed. To determine current health status, a physical examination should be conducted. This physical examination should include current vital signs such as blood pressure, pulse, respiration, and oxygen levels. The height and weight of the patients are also a critical aspect of the physical examination, as chemotherapy doses are often calculated using these metrics (5). 

Laboratory Tests 

In addition to a physical examination, laboratory tests can help determine if a patient is in a state that would allow for the chemotherapy to be tolerated. Laboratory tests that are often associated with chemotherapy include completed blood counts (CBC), complete metabolic panel (CMP), and other laboratory tests depending on the cancer type of chemotherapy being given. The CBC test is used to determine a patient’s white and red blood cell counts, as well as plasma levels. The white blood cell (WBC) count is particularly helpful in determining if patients are stable enough to receive chemotherapy, as this treatment type often drops a patient’s WBCs further. The CBC can also be assessed for other complications, such as anemia and increased risk for bleeding (5). 

Adverse Reactions 

The next portion of an assessment for patients receiving chemotherapy should include a risk assessment for adverse reactions. Assessing a patient’s age and overall health can determine if a patient is at higher risk for certain side effects of chemotherapy. Genetic factors, such as genetic predispositions, can impact a patient’s ability to metabolize certain chemotherapy drugs. This challenge can increase a patient’s risk for toxicity. Lastly, assessing a patient’s previous reactions to current chemotherapy regimens can provide valuable insight into what to expect as a patient receives chemotherapy treatments. Understanding these three potential areas of concern allows the nurse and healthcare provider to appropriately plan for preventative measures, such as pre-administration medications that reduce the risk of certain side effects (5). 

Education and Informed Consent 

While not part of the assessment itself, both education and informed consent are often paired with the assessment as both are necessary before the patient received chemotherapy treatment. Patient education should include the name of the medications they are receiving – both the chemotherapy drug itself and any supportive medications, the purposes of these medications, the potential side effects, how to appropriately treat these medications at home, as well as what medical staff will do to treat these side effects during the administration, and how long the individual treatment will take as well as how long the patient is expected to be receiving this treatment regimen (5). 

In addition to this education, the patient is to sign an informed consent agreement before receiving their first chemotherapy treatment. Informed consent is an ethical and legal requirement that ensures the patient is aware of the risks and benefits associated with chemotherapy treatment.  

While the nurse may be a witness to the signature, the nurse cannot provide the education surrounding the pros and cons of receiving chemotherapy. A licensed medical provider that ordered the chemotherapy regimen, typically a medical doctor (MD) or an advanced practice provider (APP, either a physician assistant or a nurse practitioner), must provide the education and then sign the document stating that this education was provided to the patient. Before providing any chemotherapy treatments, the nurse must ensure this document is signed by both parties and scanned into the patient’s chart. If this is not completed, the nurse should request a stop in the process and ensure this is completed to remain compliant (5). 

Epidemiology 

The epidemiology of cancer is helpful for healthcare professionals to understand, as it can impact the approach to treatment, the support provided, and the resources needed for this patient population. Cancer epidemiology includes the incidence and prevalence rates, as well as the demographics of patients receiving chemotherapy, and chemotherapy usage over time. Understanding these statistics can help healthcare professionals identify patterns, allocate resources, and develop effective treatment strategies (6). 

Globally, cancer remains one of the leading causes of morbidity and mortality. There are an estimated 19.3 million new cancer cases and nearly 10 million cancer-related deaths in 2020 alone. Chemotherapy is often used as the primary treatment for various cancer types, including breast cancer, colorectal, and other common cancer diagnoses (6). 

The cancer incidence rates refer to the number of new cancers diagnoses during a specific time frame. Cancer prevalence refers to the total number of cases at a given point. Both numbers can be utilized to determine the burden of cancer and the need for chemotherapy treatments. The American Cancer Society estimates that approximately 1.9 million new cancer cases will be diagnosed in 2021, many of which use chemotherapy as their primary treatment modality (6).  

Demographics 

In addition to these numbers, demographics can play a role in whether cancer is diagnosed, which diagnosis the patient is at risk for, and which treatment will be utilized. These demographics include age, gender, socioeconomic status, and geographic area. As patients age, particularly patients 65 years of age or older, patients are more likely to be diagnosed with cancer. A significant portion of new diagnoses fall into the 65 or older age group. This is often associated with the unique challenges of aging, such as comorbidities, the natural aging process, and the likelihood of completing cancer screenings. Knowing this information allows the healthcare team to identify the unique challenges of this age group and tailor their chemotherapy treatment accordingly (6). 

In addition to age, gender also can impact a patient’s diagnosis, treatment, and outcomes. For example, breast cancer most commonly affects women, while prostate cancer is exclusive to male patients. Understanding these gender differences in potential cancer risk allows healthcare professionals, such as nurses, to improve screening programs and tailor education accordingly (6). 

Another important consideration of demographics for cancer patients is their socioeconomic status. The socioeconomic status of patients significantly impacts access to chemotherapy and overall cancer care. Whether that means being able to afford cancer screenings and care or transportation to and from the cancer center, those of lower socioeconomic status are less likely to seek out medical care for oncology concerns than those of higher socioeconomic status. Additionally, the location of patients can be impacted by socioeconomic status. Rural cost of living is lower but so is access to cancer screenings and care (6). 

Trends in Usage 

Chemotherapy usage has evolved over the years. Historically, it has been a first-line treatment for many cancer types. However, in recent years, this no longer is the case. With advancements in research and technology, there have been new targeted therapies and immunotherapies introduced as superior alternative treatments. The shift towards personalization in treatment plans allows the patient’s genetic profile and specific characteristics to be addressed. This shift improves efficacy and reduces side effects (6). 

Additionally, recent trends indicate an increased use of combination therapies. Using radiation therapy and immunotherapy is a common example of these recent trends. Such combinations of treatments aim to reduce side effects, improve survival rates, and enhance patients’ quality of life. Lastly, chemotherapy may not be available for all cancer patients who need such treatments. Related to geographical areas and socioeconomic status, utilization of other cancer treatment types can improve these underserved patient populations and male cancer care more equitable (6). 

Understanding the epidemiology of cancer treatment is essential when developing effective public health strategies. Epidemiology also guides clinical practice and improves opportunities to address the challenges patients face in their unique situations. This knowledge lays a foundation for improving and ultimately optimizing cancer treatment to improve patient outcomes (6). 

Pathophysiology 

Chemotherapy targets and disrupts the multiplication process that allows cancer cells to grow and proliferate. Understanding how chemotherapy works at a cellular level is essential to support patients in understanding and optimizing treatment strategies during their treatment. Chemotherapy targets the cell cycle when cells grow and divide. Cancer cells often exhibit uncontrolled growth resulting in the formation of tumors. Chemotherapy aims to inhibit this growth at various phases of the cell cycle, ultimately leading to the cell’s death (1). 

Depending on the type of chemotherapy, the process of disrupting the cell cycle will vary. There are chemotherapy treatments that inhibit DNA synthesis, which causes errors in DNA replications. This leads to cell cycle arrest and apoptosis, or programmed cell death. For chemotherapies that impact RNA synthesis, this prevents the production of proteins that are necessary for cell survival and proliferation. Thirdly, chemotherapy agents that interfere with mitotic spindle formation and lead to cell death. When mitotic spindle formation is disrupted, the structures that separate chromosomes during cell division are not present and thus cancer cell growth cannot occur (1). 

Mechanisms of Action  

Chemotherapy regimens are broken into different classes based on their distinct mechanisms. The primary drug classes of chemotherapy include alkylating agents, antimetabolites, plant alkaloids, and topoisomerase inhibitors. Alkylating agents, such as cisplatin, work by adding alkyl groups to DNA. This addition leads to cross-linking and prevents DNA replication, ultimately stopping the cells’ ability to divide and grow (1).  

Antimetabolites, such as 5-fluorouracil, mimic the building blocks of DNA and RNA. Antimetabolites interfere with their cancer cell synthesis but substituting for DNA and RNA, inhibiting cell growth and division. Plant alkaloids, such as paclitaxel, disrupt the mitotic spindle which prevents proper chromosome separation during cell division. This disruption halts the cell cycle and leads to cell death. Finally, topoisomerase inhibitors, such as doxorubicin, target the enzymes that manage DNA topology during replications. Inhibition of these enzymes causes a break in the DNA, preventing cancer cell proliferation (1).  

Impact on Cells 

Chemotherapy is designed to target rapidly dividing cells. Unfortunately, chemotherapy cannot differentiate between rapidly dividing health cells versus rapidly dividing cancerous cells. Because of this, chemotherapy can impact the body in a variety of ways. First, chemotherapy impacts bone marrow by inhibiting the production of blood cells. This leads to anemia, increased risk of infection, and problems with bleeding. The gastrointestinal system can also be impacted. Some of the gastrointestinal effects seen in chemotherapy patients include nausea, vomiting, and diarrhea. Additionally, the follicles of hair can be impacted, leading to alopecia in many patients (1). 

While the goal is to maximize the impact of chemotherapy on cancerous cells while minimizing the impact on healthy cells, the challenge lies in the inherent difference in how the cells respond to treatment. Continued research is needed to enhance the specificity of chemotherapy drugs. Through additional research and treatment progression, improved efficacy against cancer cells can be achieved. Understanding these dynamics is crucial for optimizing treatment strategies and improving outcomes of cancer patients (1). 

Side Effects 

Chemotherapy poses the risk of various side effects. These side effects will be dependent on the type of chemotherapy, the dose, the frequency, and the cancer diagnosis. Additionally, the patient’s overall health status may make patients more susceptible to experiencing side effects of chemotherapy at increased intensity. Being aware of the most commonly experienced side effects allows healthcare professionals to educate patients on what to expect when receiving their chemotherapy, as well as which symptoms need to be reported or escalated for emergent treatment and recognize signs and symptoms of serious adverse reactions (7). 

The most experienced side effects of chemotherapy include nausea and vomiting, fatigue, neutropenia, alopecia, and mucositis. Nausea and vomiting occur because of the chemotherapy’s impact on the gastrointestinal tract and central nervous system. To combat this, antiemetics are often prescribed before and during chemotherapy administration. Fatigue is the next commonly experienced side effect of chemotherapy. Fatigue is multifactorial, including anemia, metabolic changes, and the psychological stress of a cancer diagnosis. To combat this, a healthy diet and exercise, as well as quality sleep plus resting periods throughout the day is recommended (7). 

Next, neutropenia is a concern for patients undergoing chemotherapy treatments. Chemotherapy can reduce the patient’s white blood cell count, increasing the patient’s risk for infection. Patients must be carefully monitored before, during, and after chemotherapy treatment to catch minor infections before they become more severe. Alopecia, or hair loss, is another concern for patients undergoing chemotherapy treatment. Because the hair follicle is a rapidly dividing cell, chemotherapy often targets this and leads to partial or total hair loss as treatments continue. Patients’ hair may return after they discontinue treatment, but wigs and head coverings can be utilized during the transition of hair loss and regrowth (7). 

Another serious concern of side effects includes mucositis. Mucositis includes mouth cores, pain, and difficulty eating or swallowing. This is related to the mucous membranes being targeted by chemotherapy, making healthy cells impacted negatively. Beyond decreasing a patient’s ability to intact the necessary nutrients to maintain health and well-being, the mouth sores patients experience can cause pain and lead to an increase in infection (7). 

Adverse Reactions 

Beyond the commonly experienced side effects, certain symptoms and intensity of such reactions can be detrimental to a patient’s health. These adverse reactions need to be closely monitored by not only the healthcare team, but the patients and the patients support system. The following adverse reactions require immediate medical attention, including anaphylaxis, cardiotoxicity, hemorrhagic events, and severe infections (4). 

Anaphylaxis is a rare but serious allergic reaction to the chemotherapy agents being provided. Symptoms include difficulty breathing, swelling of the face and throat, rapid heartbeat, and low blood pressure. Cardiotoxicity is possible for certain chemotherapy treatments, such as anthracyclines, as they lead to damage of the heart muscle itself. Symptoms include shortness of breath, chest pain, and unusual fatigue (4). 

Hemorrhagic events may occur because of a drop in platelet counts. As these numbers drop, the risk of bleeding increases. Patients should be educated on the signs and symptoms of bleeding, including unusual bruising, blood in their urine or stool, and as well as prolonged bleeding from cuts or injuries. Additionally, severe infections may occur related to the immunosuppression side effects of chemotherapy. To monitor for severe infection, symptoms of fever, child, redness, and swelling should all be assessed for (4). 

Monitoring and Reporting 

Effective monitoring and reporting of symptoms and adverse reactions is a significant component of chemotherapy management. Healthcare providers should conduct a comprehensive monitoring plan that includes regular assessments, patient education, symptom management, and proper documentation. Regular assessments should include a physical examination, regular blood tests to monitor blood counts and organ function, as well as vital sign collection and assessment (4). 

Patient education should be an ongoing portion of the patient’s cancer care journey. Educating patients on how to recognize and report symptoms promptly can reduce side effects and prevent severe reactions. Symptom management should focus on managing the most common side effects using natural approaches and medication treatments such as antiemetics. Patients should be educated on how to treat symptoms at home as well as which symptoms warrant immediate medical attention (4). 

Lastly, documentation of these symptoms and side effects can aid in monitoring the progress or decline of a patient. Through appropriate documentation of these, the best clinical decisions and adjustments to treatment plans can occur. Through understanding the most common side effects of chemotherapy, recognizing the potential and serious adverse reactions, and proper monitoring, healthcare providers can significantly improve the safety and quality of patient care during chemotherapy administration (4). 

Etiology 

Chemotherapy is a vital component of cancer treatment and is indicated in various scenarios based on the patient’s type, stage, and characteristics of their cancer. A patient’s health status also impacts the choice of chemotherapy utilized. Understanding the indications of such treatments can help tailor a patient’s treatment plan that maximizes efficacy while minimizing the associated risks. The indications for chemotherapy include curative, palliative, adjuvant, or neoadjuvant (2). 

Curative intent is to remove the cancer cells entirely from a patient’s body. This approach is utilized for aggressive cancers that have yet to metastasize. Palliative treatment is used when a cure is not possible. In this situation, palliative treatment is meant to alleviate symptoms of cancer, improve the quality of life, and prolong the patient’s survival. This approach has to be carefully monitored to reduce the potential side effects associated with chemotherapy treatment while balancing the benefits of providing such treatment (2). 

Adjuvant and neoadjuvant are often used in a curative manner but can also be used for palliative purposes. Adjuvant treatment refers to receiving chemotherapy treatment after surgical intervention has been completed. This is commonly used when surgery is incapable of removing all cancer cells or there is a high likelihood of cancer quickly returning. Neoadjuvant treatment focuses on providing chemotherapy before completing surgical interventions. This approach is conducted when the tumor is too large or in a risky area for surgery to be completed. Through the use of chemotherapy, the tumor can be shrunk to improve the chance of surgical intervention success (2). 

Chemotherapy Types Based on Diagnosis 

Chemotherapy can be used for more than just cancer diagnoses. However, these treatments are most commonly used for a wide range of cancer types. Some of the diagnoses that chemotherapy is commonly prescribed for include leukemias, lymphomas, breast, colorectal, lung, and ovarian cancers (1). 

Leukemias is a type of cancer that arises from blood-forming tissue. Leukemias, such as lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) often require aggressive chemotherapy regimens. Lymphoma, either Hodgkins or non-Hodgkins’s lymphoma, are frequently treated with chemotherapy. Chemotherapy may also be used in conjunction with other treatments, like radiation, for leukemia diagnoses (1). 

Breast cancer may be treated by chemotherapy. This treatment is used for both early and advanced stages of breast cancer, particularly in hormone receptor-negative cases or aggressive subtypes. Colorectal cancer responds well to certain chemotherapy regimens. This is particularly true for targeted therapies or adjuvant treatment after surgery (1). 

Lung cancer, both small cell and non-small cell types, are typically treated with chemotherapy. Chemotherapy is particularly beneficial for lung cancer patients with advanced disease or metastatic lung cancer. Ovarian cancer is standardly treated with chemotherapy. This is provided after surgery to reduce the risk of recurrence (1). 

Factors Influencing Treatment 

Several factors impact a patient’s appropriateness for chemotherapy treatment. The treatment chosen will be influenced by tumor type, stage of cancer, patients’ overall health, and the patient’s preferences. Tumor types are the biological characteristics of the tumor, including its histology and genetic mutations. These factors can significantly influence treatment decisions, as certain tumors are more responsive to chemotherapy while others may require targeted therapy or immunotherapy (10). 

A patient’s stage of cancer determines the extent of disease progression. This information can be utilized to determine which chemotherapy is most appropriate, as early-stage cancers tend to be treated with a curative approach, while more advanced stages may need a palliative approach instead. The patient’s overall health status also needs to be considered. This would include age, comorbidities, and performance status. Patients with higher health status can tolerate more aggressive therapies, while those dealing with medical challenges or limitations may require modified approaches (10). 

Lastly, the patient’s preference on which approach and which type of treatment should be considered. Things that may influence a patient’s preferences include a patient’s values, belief system, and cultural background. By providing the patient with education surrounding goals of treatment, potential side effects, and quality of life, the patient can determine which treatment aligns with their preferences (10). 

Chemotherapy serves as a crucial intervention for many types of cancer. Depending on the tumor characteristics and the patient’s health, chemotherapy may be a first-line treatment. Understanding these factors helps the nurse and other healthcare professionals to formulate personalized treatment plans. Through this personalization, patients can experience improved outcomes and support patients at a greater depth throughout their cancer care journeys (10). 

Treatment  

Treatment decisions for cancer patients will consider many items. First, determining the intent of treatment will be important to understand. Here are two main treatment goals: curative or palliative. Curative chemotherapy aims to eliminate cancer to cure the patient fully. This type of treatment is generally reserved for cancers that are localized or have not spread significantly. It often involves aggressive strategies designed to eradicate all cancer cells and achieve remission. For many patients, this approach can be successful, resulting in a cure and enhancing both survival rates and overall quality of life (4). 

In contrast, palliative chemotherapy prioritizes alleviating symptoms and enhancing the quality of life for patients with advanced or metastatic cancer. The primary goal is not to cure the disease but to manage the tumor burden, alleviate symptoms, and extend survival as much as possible. Palliative chemotherapy is typically administered at lower doses or with less aggressive regimens to minimize side effects. This approach aims to improve patients’ quality of life while maximizing the time they have left, regardless of their terminal diagnosis (4). 

Chemotherapy is a vital component of cancer treatment and is indicated in various scenarios based on the patient’s type, stage, and characteristics of their cancer. A patient’s health status also impacts the choice of chemotherapy utilized. Understanding the indications of such treatments can help tailor a patient’s treatment plan that maximizes efficacy while minimizing the associated risks. The indications for chemotherapy include curative, palliative, adjuvant, or neoadjuvant (2). 

Adjuvant and neoadjuvant therapies are primarily used with curative intent but can also serve palliative purposes. Adjuvant treatment involves administering chemotherapy after surgery, particularly when the surgery cannot remove all cancer cells or when there is a high risk of recurrence. Neoadjuvant treatment, on the other hand, is given before surgery to shrink the tumor, especially if it is too large or located in a challenging area for surgical removal. This approach aims to enhance the likelihood of successful surgery (2). 

Chemotherapy Types Based on Diagnosis 

While chemotherapy can be used for various conditions beyond cancer, it is most commonly prescribed for a range of cancer types. Key diagnoses that often require chemotherapy include leukemias, lymphomas, breast cancer, colorectal cancer, lung cancer, and ovarian cancer. Leukemias arise from blood-forming tissues, with types such as acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) typically necessitating aggressive chemotherapy regimens. Both Hodgkin and non-Hodgkin lymphomas are frequently treated with chemotherapy, which may also be combined with other therapies like radiation (1). 

Breast cancer treatment includes chemotherapy for both early and advanced stages, particularly in cases that are hormone receptor-negative or aggressive. Colorectal cancer often responds well to specific chemotherapy regimens, especially targeted therapies and adjuvant treatments following surgery. Lung cancer, including both small cell and non-small cell types, is usually treated with chemotherapy, which is especially beneficial for patients with advanced or metastatic disease. Ovarian cancer is also typically treated with chemotherapy, often administered post-surgery to lower the risk of recurrence (1). 

Factors Influencing Treatment 

Several factors determine a patient’s suitability for chemotherapy. Key considerations include tumor type, cancer stage, overall health, and patient preferences. Tumor Type, or the biological characteristics of the tumor, such as its histology and genetic mutations, can greatly influence treatment decisions. Some tumors respond better to chemotherapy, while others may require targeted therapies or immunotherapy (10). 

Cancer Stage, or the stage of cancer reflects the extent of disease progression. This information helps guide treatment choices; early-stage cancers are often treated with curative intent, whereas advanced stages may require a palliative approach. Overall, Health, or a patient’s health status—including age, comorbidities, and performance status—also plays a crucial role. Patients in better health may tolerate more aggressive therapies, while those facing medical challenges might need adjusted treatment plans (10). 

Patient preferences regarding treatment types and approaches are important. Factors influencing these preferences can include values, belief systems, and cultural backgrounds. By educating patients about treatment goals, potential side effects, and impacts on quality of life, they can make informed choices that align with their values (10). 

Self-Management 

Effective self-management is crucial for patients undergoing chemotherapy. Chemotherapy can significantly enhance treatment outcomes and improve quality of life. This involved educating patients about managing side effects, the importance of adhering to treatment schedules, accessing support resources, and making appropriate lifestyle choices.  

This education should start with managing side effects. Educating patients about common side effects should include education regarding nausea and vomiting, fatigue, neutropenia, alopecia, and mucositis. First, nausea and vomiting occur due to the effects of chemotherapy on the gastrointestinal tract and central nervous system. To alleviate these symptoms, antiemetics are often prescribed before and during treatment. Next, fatigue is another frequently reported side effect, which can arise from multiple factors such as anemia, metabolic changes, and the psychological stress associated with a cancer diagnosis. To help manage fatigue, a balanced diet, regular exercise, quality sleep, and rest periods throughout the day are recommended (5). 

Neutropenia is a significant concern for patients receiving chemotherapy, where the treatment can lower white blood cell counts, heightening the risk of infections. Patients need careful monitoring before, during, and after treatment to detect any infections early on. Then, alopecia (or hair loss), is a common issue due to chemotherapy targeting rapidly dividing cells, including hair follicles. This can result in partial or total hair loss, though hair typically regrows after treatment ends. In the meantime, patients may use wigs or head coverings during this transition (5). 

Lastly, mucositis is a condition that involves painful mouth sores and difficulty eating or swallowing, as chemotherapy can damage the mucous membranes. Mucositis can hinder a patient’s ability to take in essential nutrients and increase the risk of infections, making it a serious concern during treatment (5). 

Adherence to the prescribed regimen is necessary for the effectiveness of chemotherapy. Missing doses or delaying treatments can diminish their efficacy and can increase the risk of cancer recurrence. Patients should be encouraged to maintain consistency by using a calendar or reminder app. This will aid in tracking treatments and oral chemotherapy or supportive drugs to reduce symptoms. Additionally, the healthcare provider should actively discuss barriers the patient is facing to appropriately address the challenges during their cancer care journeys. Some commonly experienced barriers to care include transportation, financial, and psychosocial barriers to care (12). 

Resources for Support 

When barriers to care are present, it is important to provide support and resources to reduce the burden of the cancer diagnosis. Some additional resources to be provided to cancer patients include connecting patients with support groups, counseling services, and additional educational resources.  

Support groups can be particularly helpful for patients as they provide them with a safe space to discuss their challenges, fears, and emotional challenges while being surrounded by those who are experiencing similar experiences.  

Counseling services help connect patients with trained professionals who can provide strategies to patients to manage the stress, anxiety, and depression that come with a cancer diagnosis. Educational resources, such as websites, pamphlets, and books, provide patients with information about chemotherapy, coping strategies, and self-care techniques (13). 

Nutrition and Lifestyle Choices 

Beyond medical interventions, nutritional and lifestyle adjustments may be necessary and encouraged as patients navigate their cancer care journeys. A balanced diet of fruits, vegetables, whole grains, and lean proteins helps provide patients with the nutrients they need to maintain a healthy immune system and the energy they need to tolerate treatment. During cancer treatment, patients experience nutritional deficiencies related to side effects of treatment including nausea, vomiting, and fatigue (14). 

Hydration is also an important aspect of nutrition. By remaining well hydrated, patients reduce the challenges associated with dehydration, reduce the overall impact of symptoms from chemotherapy, and improve their overall health. Physical activity should also be encouraged. 150 minutes per week of moderate-intensity activity helps alleviate fatigue, improve mood, and enhance overall well-being. Finally, stress management is an important aspect of lifestyle changes. Reducing stress through yoga, meditation, and deep breathing exercises helps patients cope with the emotional challenges of cancer (14). 

Research 

Advancements in chemotherapy research continue to evolve and improve cancer treatments. As this evolution occurs, improvements in safety and efficacy are present. Understanding current cancer research, including clinical trials, emerging therapies, and advancements in treatment, can assist in improving patient outcomes. Some of the current research in the oncology space includes personalized medicine, combination therapies, and novel drug formulations (15). 

Personalized medicine focuses on using a patient’s genetic profiling and biomarker testing to tailor treatment regimens to target specific characteristics of the patient’s tumor. This improves response rates and reduces unnecessary exposure to ineffective therapies.  

Combination therapies, such as immunotherapy and radiation therapy, show promising synergistic effects. These combinations enhance overall treatment effectiveness while reducing the potential side effects associated with high doses of chemotherapy. Novel drug formulations, such as nontechnology and liposomal formulations, improve the treatment’s effectiveness in targeting cancer cells. This enhances the therapeutic index by concentrating on the tumor while sparing the health issues (15). 

Clinical Trials 

Clinical trials play a crucial role in the ongoing development of cancer treatments. Clinica trials provide a structured framework for testing new treatments and assessing their safety and efficacy. Clinical trials are separated into different clinical trial phases, phases I to IV. Phase I focuses on safety and dosing, while phase II assesses efficacy. Phase III compares new treatments with standard therapies, while phase IV focuses on post-marketing and the ongoing impact of treatment on the patient overall (15). 

Emerging Therapies 

Targeted therapies identify specific molecular targets within the cancer cells that can be attacked with new drugs that are designed to inhibit their growth. Targeted therapies offer more effective treatment options with fewer side effects. Immunotherapy, in combination with chemotherapy regimens, is gaining popularity. This approach can improve outcomes while reducing experienced symptoms (16). 

Immunotherapy by itself is also gaining momentum. Utilizing the body’s immune system shows great promise in enhancing effective treatment. Similarly, biologics and antibody conjugat4es are emerging as promising treatment options. These include monoclonal antibodies and antibody-drug conjugates (ADCs). These are designed to deliver chemotherapy directly to cancer cells while minimizing damage to normal cells. These are in early trials currently but have encouraging results. Novel drug approvals are gaining popularity as new agents and formulations are being created. This expands the options available to oncologists, allowing for more tailored options based on the patient’s individual needs and tumor characteristics (17). 

Conclusion

Administering chemotherapy for a cancer patient is both rewarding and challenging. The ability to contribute to a patient’s journey toward treatment or cure can be deeply fulfilling. However, the experience of being diagnosed and treated for cancer can also lead to significant suffering for patients. As healthcare providers supporting patients through this process, it is crucial to understand safe chemotherapy administration techniques. 

This involved a thorough knowledge of chemotherapy drugs, their intended purposes, potential side effects, and appropriate monitoring strategies. Educating patients about these aspects and their overall treatment plan is vital, as it enhances their adherence to the prescribed regimen and ultimately leads to better outcomes. By ensuring safe chemotherapy administration, healthcare providers can offer support to patients during this pivotal time in their lives.
