Quality of life in operable colon cancer patients receiving oral compared with intravenous chemotherapy: results from National Surgical Adjuvant Breast and Bowel Project Trial C-06.

摘要

PURPOSE: We compared health-related quality of life (HRQL), symptoms, and convenience of care (COC) in patients with stage II/III carcinoma of the colon who received either oral uracil/ftorafur (UFT) plus leucovorin (LV) or standard intravenous (IV) fluorouracil (FU) plus LV as adjuvant chemotherapy. PATIENTS AND METHODS: We measured HRQL with the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) questionnaire, Short Form-36 Vitality Scale (SF-36), and a Quality of Life Rating Scale (QLRS) at baseline, once during chemotherapy, and at 1 year. We used the Symptom Distress Scale (SDS) and treatment-specific Symptom Checklist (SCL) to assess symptoms and a modified Burden of Care form to assess COC at baseline, on day 1 of each treatment cycle, and at 1 year. Repeated measures analyses controlling for demographic variables and baseline scores were used for statistical comparisons. RESULTS: The study accrued 1,608 patients, 803 to the FU arm and 805 to the UFT arm. There were no differences between the arms in overall FACT-C scores, FACT-C scores within the subscales of colon-specific, physical, emotional, social, and functional health, or QLRS scores. Patients taking UFT reported substantially higher COC. Statistically significant but small differences were observed for SF-36, favoring FU, and for SDS and SCL, both favoring UFT. CONCLUSION: Patients perceive adjuvant treatment with UFT + LV as more convenient than standard IV treatment with FU + LV. Both regimens are well tolerated and do not differ in their impact on HRQL.
