Abstract
Aims and objectives: The aim of this paper was to study the impact of neoadjuvant chemoradiation on downstaging of locally advanced rectal carcinoma, sphincter saving procedures and toxicity profile of chemoradiation. Method: 31 patients were studied who had locally advanced adenocarcinoma of rectum. They were treated preoperatively with 20 frations of 225 cGy (5 days/wk) radiation (total of 45Gy over 28 days). Chemotherapy consisted of 5-FU (500mg/m.sq) only for day 1, 2, & 3. After an interval of of 4-6 wks, all patients were submitted to surgery.The principles of TME was Results: The median follow up in our study was 1year. At 1 year the overall survival in operated cases was 100% with no disease relapse. 67% of patients underwent low anterior resection,6.5% had proctosigmoidectomy with end colostomy,16.5% had a palliative surgical procedure, 6.5% became non compliant after neoadjuvant and 3.2% expired preoperatively during chemoradiation. At the time of surgery 82.6% of patients had pathological downstaging of tomour and 45.4% had lymphnode downstaging.Consequently 67.7% of patients underwent a sphincter preserving surgical procedure. The incidence of complication was 29% with grade 2 mucositis and 9.7% with grade 1 mucositis. Myelosuppression was seen in non. Conclusion: Significant downstaging of disease was seen with this regime of treatment and with improved subsequent sphincterv preserving procedures with acceptable toxicity profile
