OBJECTIVES: To examine the toxicity experienced by a cohort of older women receiving adjuvant chemotherapy for breast cancer and the longitudinal effect on their functional status and quality of life (QOL). DESIGN: A geriatric assessment measuring functional status, comorbidity, mood, nutritional status, and QOL was performed before chemotherapy, at the end of chemotherapy, and 6 months later. SETTING: This prospective longitudinal study was conducted at Memorial Sloan-Kettering Cancer Center, New York, New York. PARTICIPANTS: Fifty patients aged 65 and older with Stage I to III breast cancer receiving any adjuvant chemotherapy; 49 were evaluable. MEASUREMENTS: The chemotherapy regimen and the toxicity to chemotherapy were recorded. A geriatric assessment was performed before the start of chemotherapy, on completion of chemotherapy, and 6 months after completion of chemotherapy. QOL testing was performed at the same times. RESULTS: Patients (mean age 68, range 65-84) received an anthracycline-based chemotherapy regimen (n = 15) or cyclophosphamide 600 mg/m(2) intravenously (IV), methotrexate 40 mg/m(2) IV, 5-fluorouracil 600 mg/m(2) IV every 3 weeks for eight cycles (n = 34). Grade 3 or 4 toxicity occurred in 53% (n = 26), hematological toxicity in 27% (n = 13), and nonhematological toxicity in 31% (n = 15). Despite toxicity, there was no significant longitudinal change in functional status or QOL. CONCLUSION: Despite toxicity from adjuvant chemotherapy, this cohort of relatively young older patients maintained their functional status and QOL from before chemotherapy to 6 months postchemotherapy. Subtle changes in higher-order functioning would require assessment using different geriatric assessment tools.
