ABSTRACT
BACKGROUND:
To evaluate the efficacy and safety of the combination of oxaliplatin and S-1 (OS) in treating metastatic colorectal cancer. PATIENTS ANDMETHODS:
Eligible patients were those with measurable lesions, no previous history of chemotherapy (except adjuvant chemotherapy), an age of 18-70 years, and an Eastern Cooperative Oncology Group performance status of zero to two. Oxaliplatin 130 mg/m(2) was administered i.v. on day 1, and S-1 40 mg/m(2) b.i.d. was administered orally on days 1-14, every 3 weeks.RESULTS:
Forty-eight patients (median age, 56 years) were enrolled 23 had colon cancer, seven rectosigmoid colon cancer; and 18 rectal cancer. Of the 48 patients, 31 were diagnosed with metastatic cancer and 17 had relapsed cancer after surgery, with adjuvant chemotherapy or chemoradiotherapy. In total, 413 cycles were administered (median 6 per patient; range 2-24). Toxicity was evaluated in 48 patient and response in 46. Major toxic effects were grade 3/4 thrombocytopenia (13%) and neutropenia (10%). The overall response rate was 54% [95% confidence interval (CI) 40% to 68%]. The median time to progression and median survival time were 8.5 (95% CI 6.2-10.9) months and 27.2 (95% CI 20.3-34.0) months, respectively.CONCLUSIONS:
These data indicate that the OS regimen is effective and well tolerated in patients with advanced colorectal cancer.
