The Outcome of Neoadjuvant Chemo Radiotherapy and Surgery in Carcinoma Rectum: Our Experience

Abstract

Vinay HG, Vybhav R

Introduction: Carcinoma of the rectum is not only a medical but a social problem. Adenocarcinoma of the rectum accounts for 30% of these cancers. Locally advanced cancers of the rectum i.e., stage 2 and 3 diseases prove to be a challenge with respect to its management. Present guidelines state that the use of neoadjuvant chemoradiotherapy to downstage the locally advanced carcinomas of the rectum to have a positive impact on not only the survival but also the quality of life post-treatment viz., by allowing better resection margins to preserve the sphincter mechanism by performing a coloanal anastomosis.
Objectives: To assess the locoregional response rates determined by the measurement of margin of clearance from the anal verge, organ preservation (sphincter-saving operations), and histopathological findings in post CRT surgical specimen.
Materials and methods: This study included a total of 33 patients which were diagnosed with locally advanced rectal cancer who presented in the department of General Surgery, Vydehi Hospital, Bangalore. The patients in this series were subjected to pre-operative CRT, loco-regional response rates and the number of sphincter preserving surgeries performed were assessed.
Results: Downstaging of the tumor was achieved in 91% of the cases.
Conclusion: From this study, an interpretation can be made that following CRT there is a significant downstaging and increased ability to perform sphincter-saving procedures.
