Summary
Brief summary (as posted)
Preoperative induction chemotherapy has been successfully used in a variety of malignancies and provides several advantages over postoperative therapy. Combination of 5-FU/Leucovorin/CPT-11 has demonstrated significantly better response rate than 5-FU/Leucovorin alone. Replacing 5-FU with oral capecitabine in combination with CPT-11 has emerged as a potentially more effective, safe and convenient treatment option for metastatic colorectal cancer. Capecitabine is also well tolerated in concurrent treatment with radiation. Recent data has shown that preoperative radiation appears to be significantly more effective in increasing resectability rates. This trial will investigate the activity of capecitabine and CPT-11 combination in the preoperative setting followed by chemoradiation with capecitabine in locally advanced rectal cancer to improve response and decrease local recurrence. We will also study whether TS, TP, DPD and carboxyesterase expressions correlate with the objective response rate with this chemotherapy and chemoradiation regimen.

- description
- · To determine the pathological response rate of preoperative chemotherapy with capecitabine and irinotecan followed by combined modality chemoradiation with capecitabine in patients with locally advanced rectal cancer. Pathological response was defined in the protocol as the proportion of complete (pCR) and non-complete pathological response (pNCR) among all evaluable patients.
