BACKGROUND: We undertook this study to evaluate early surgical complications and long-term results after preoperative radiotherapy and chemotherapy (RCT) using 5-fluorouracil (5-FU) and oxaliplatin (OXA) for rectal cancer. METHODS: Forty six TNM stage II-III rectal cancer patients were studied, who were given preoperative RT (50.4 Gy/28 fractions) combined with 5-FU (200-225 mg/m(2)/day by continuous venous infusion) and weekly OXA (25-60 mg/m(2)). Major complications and reoperations were recorded overall, whereas outcome analyses were performed only for patients who received the recommended regimen dosage. RESULTS: Forty three patients (M:F, 25:18; median age 59 years) were available for analysis. All patients received the planned RT dose. There were no postoperative deaths; seven patients had early major surgical complications, four requiring re-operation. One additional patient had a second surgical procedure due to a duodenal fistula complicating the resection of an aortic aneurysm performed concomitantly with rectal cancer surgery. At a median follow-up of 49 months, two of the 23 patients treated at the recommended doses developed recurrence (one local, and one local and distant), and two died of cancer progression. Following the Kaplan-Meier method, the estimated 5-year overall and disease-free survival rates were 92 and 89%, respectively. CONCLUSIONS: The preoperative RCT regimen used in the present study incurs a low rate of recurrence with an acceptable surgical morbidity.

Abstract

BACKGROUND: We undertook this study to evaluate early surgical complications and long-term results after preoperative radiotherapy and chemotherapy (RCT) using 5-fluorouracil (5-FU) and oxaliplatin (OXA) for rectal cancer. METHODS: Forty six TNM stage II-III rectal cancer patients were studied, who were given preoperative RT (50.4 Gy/28 fractions) combined with 5-FU (200-225 mg/m(2)/day by continuous venous infusion) and weekly OXA (25-60 mg/m(2)). Major complications and reoperations were recorded overall, whereas outcome analyses were performed only for patients who received the recommended regimen dosage. RESULTS: Forty three patients (M:F, 25:18; median age 59 years) were available for analysis. All patients received the planned RT dose. There were no postoperative deaths; seven patients had early major surgical complications, four requiring re-operation. One additional patient had a second surgical procedure due to a duodenal fistula complicating the resection of an aortic aneurysm performed concomitantly with rectal cancer surgery. At a median follow-up of 49 months, two of the 23 patients treated at the recommended doses developed recurrence (one local, and one local and distant), and two died of cancer progression. Following the Kaplan-Meier method, the estimated 5-year overall and disease-free survival rates were 92 and 89%, respectively. CONCLUSIONS: The preoperative RCT regimen used in the present study incurs a low rate of recurrence with an acceptable surgical morbidity.
