Abstract
INTRODUCTION: Capecitabine provides an attractive alternative to intravenous (IV) 5-flourouracil (5-FU) in chemoradiation regimes for rectal cancer by avoiding the need for intravenous access and inpatient stay. We aimed to compare retrospectively the efficacy of concurrent capecitabine with IV 5-FU in preoperative pelvic chemoradiation schedules for rectal cancer in our centre. METHOD: Patients treated from January 2005 to June 2007 were included. Information was collected on patient characteristics; treatment details; pathological response to treatment; recurrence and survival. All statistical analyses were performed using SPSS V17. RESULTS: All patients had pelvic radiation. Ninety-nine patients were treated with capecitabine and 97 with 5-FU. The two groups were well matched for age, sex and TNM stage. There were significantly more PS (performance status) 0 patients in the capecitabine group (51%vs 30%) (P = 0.001). Of the 99 patients in the capecitabine group, 91 (92%) were able to undergo surgery with 84 (93%) achieving R0 resection. In the 5-FU group, these proportions were 87 (90%) and 70 (80%). The difference in the rate of R0 resection was statistically significant (P = 0.024). The APR rate was 35% in the capecitabine group compared with 47% in the 5-FU group (P = 0.06). There was no significant difference in pathological complete response (pCR) rates between capecitabine (14%) and 5-FU(12%). A higher pCR rate (30%) was observed in patients who underwent a brachytherapy boost (P = 0.051). There were three local recurrences in the whole patient group, (capecitabine 1; 5-FU 2). Thirty-five patients had distant metastases, 14 in the capecitabine and 21 in the 5-FU group. There was no significant difference in the risk of recurrence between the two groups. Six patients in each group had grade 3 toxicity with diarrhoea being more common with capecitabine. CONCLUSIONS: Preoperative chemoradiotherapy with capecitabine for rectal cancer is efficacious and comparable to 5-FU (IV). It is more convenient, is well tolerated and avoids the need for inpatient admission.
