AIMS: To evaluate whether pre-operative chemo-radiotherapy (CRT) improves the sphincter preservation rate for distal rectal cancers within 3 cm of the anal verge. METHODS: Between January 2001 and December 2004, 49 patients underwent surgery with or without pre-operative CRT for primary rectal adenocarcinoma within 3 cm of the anal verge. Clinical data were retrospectively reviewed, including stage workups, surgical records and pathology records to determine sphincter preservation rate and the factors influencing sphincter preservation. RESULTS: Of 49 patients with rectal tumours within 3 cm of the anal verge, 31 underwent pre-operative CRT followed by surgery (CRT group), and 18 underwent surgery alone (non-CRT group). Sphincter preservation was possible in 11 of 31 CRT patients, and only one of 18 non-CRT patients (p=0.036). The factors most influencing sphincter preservation were reduction in tumour size (p=0.005) and downstaging (p=0.001) following pre-operative CRT. CONCLUSION: We could observe that sphincter preservation was improved in CRT group with statistical significance when compared to non-CRT group in our study patients with rectal cancer within 3 cm of the anal verge.
