Chemotherapy and Biotherapy Agents Objectives At the completion of this session the participant will be able to: ◦ Identify common side effects for individual medications ◦ Describe nursing interventions for chemotherapy and biotherapy medications ◦ Discuss the principles of chemotherapy administration Chemotherapy Agents 2 Chemotherapy Agents Chemotherapy Agents 3 Agent: Cyclophosphamide (Cytoxan®; Neosar®) Indications Autoimmune Diseases PTLD Renal Disease Side Effects: Common ◦ ◦ ◦ ◦ ◦ Anorexia Nausea, vomiting Myelosuppression Alopecia Gonadal dysfunction/sterility Route: IV Special Considerations ◦ Administration of high doses of cyclophosphamide should be preceded & followed by high volume IV hydration and mesna ◦ WBC nadir between 9-15 days (recovery by 21 days) Occasional ◦ Hemorrhagic cystitis ◦ SIADH Chemotherapy Agents 4 Agent: Cyclophosphamide (Cytoxan®; Neosar®) Nursing Considerations: ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ Maintain adequate hydration, urinary output Check urine for blood and specific gravity Administer early in the day when possible Encourage urination q 2 hours and before going to bed for the night Administer over 15-60 minutes to avoid unpleasant side effects such as lightheadedness, tearing, nausea, perioral numbness, itchy nose Can be mixed with Mesna Mesna should be given exactly as ordered, and on time Nausea/vomiting delayed for 4-8 hours, therefore administer antiemetics prior to cyclophosphamide, at appropriate intervals, and the following morning after administration Chemotherapy Agents 5 MESNA (Mesnex®) Maybe used with cytoxan ◦ Cytoxan is a Pro-drugs: requires biotransformation by hepatic microsomal enzymes before expressing alkylating activity ◦ Hepatic biotransformation creates active & inactive metabolites, mainly excreted in urine: main metabolite = acrolein ◦ Hemorrhagic cystitis is a unique toxicity from this group of drugs caused by acrolein. How Does Mesna Work? ◦ Binds with the metabolite in urine ◦ Does not bind on a cellular level, therefore, does not counteract cytotoxic effects of cytoxan ◦ MUST GIVE DRUG ON SCHEDULE! Chemotherapy Agents 6 Agent:Vincristine Sulfate (Oncovin®) Indications: ITP Side Effects Common ◦ Local ulceration if extravasated ◦ Hair loss ◦ Loss of deep tendon reflexes Occasional ◦ Constipation ◦ Jaw pain Route: IV Special Considerations ◦ Refrigerate and protect from light for continuous infusions ◦ Liver dysfunction or concomitant radiation therapy to the liver may enhance toxicity ◦ Should have special overwrap label that bears the statement, “Fatal if given intrathecally. For intravenous injection only.” ◦ Infants may have difficulty sucking because of jaw pain ◦ Maximum single dose: 2 mg regardless of body surface area (BSA). A few disease protocols do not cap the dose at 2 mg. Always check. Chemotherapy Agents 7 Agent:Vincristine (Oncovin®) Nursing Considerations: ◦ Vesicant – severe tissue damage if extravasation occurs ◦ Stool softeners may be given prophylactically, or for constipation Chemotherapy Agents 8 Agents: Daunorubicin (Daunomycin, Cerubidine®) & Doxorubicin (Adriamycin PFS®; Adriamycin RDF®; Rubex®) Indications: ◦ PTLD Route: IV Side Effects Common ◦ ◦ ◦ ◦ ◦ ◦ Subclinical cardiac arrhythmias Nausea, vomiting Local ulceration if extravasated Pink or red color to urine Myelosuppression Alopecia Special Considerations ◦ Cardiac studies with echocardiogram or multiple-gated arteriography (MUGA) scan should be done periodically to monitor cardiac function – must have acceptable cardiac ejection fraction ◦ Monitor cumulative dose ◦ Dose adjustments for renal/hepatic abnormalities ◦ Radiation recall ◦ Leukocyte and platelet nadirs occur in 5-10 days; recover within 3 weeks Occasional ◦ Cardiomyopathy Chemotherapy Agents 9 Agents: Daunorubicin (Daunomycin, Cerubidine®) & Doxorubicin (Adriamycin PFS®; Adriamycin RDF®; Rubex®) Nursing Considerations: Vesicant – severe tissue damage if extravasation occurs Continuous infusions-protect from light Educate that there may be pink or red color to urine Inspect oral cavity; encourage good oral hygiene Research suggests that sucking on ice cubes or popsicles during infusion may decrease incidence of mucositis ◦ Change diapers frequently to prevent skin breakdown ◦ ◦ ◦ ◦ ◦ Chemotherapy Agents 10 Agent: Mitoxantrone Hydrochloride (Novantrone®) Indications: MS Route: IV Common Side Effects ◦ Bone marrow suppression.
