ROBERTSON, B et al. Treatment of carcinoma of the anal canal at Groote Schuur Hospital. SAMJ, S. Afr. med. j. [online]. 2012, vol.102, n.6, pp. 559-561. ISSN 0256-9574.
OBJECTIVES: Chemoradiation is the treatment of choice for squamous carcinoma of the anal canal, resulting in the same local control rates as surgery but with the advantage of organ function preservation. We aimed to review all cases of anal canal carcinoma treated at Groote Schuur Hospital between 2000 and 2004 and to assess treatment outcome. METHODS: The records for 31 patients presenting during this period were reviewed. Patient and tumour characteristics were recorded. Twenty-six patients were treated with chemoradiation. Local failure-free, colostomy-free and overall survival were calculated using the Kaplan-Meier method. RESULTS: Compared with the literature, the median patient age was younger and the stage was more advanced in this study. The complete response rate for all stages with chemoradiation was 80%. The local failure-free survival at 5 years was 60.7%. Colostomy-free and overall survival at 5 years were 59.2% and 65.6%, respectively. CONCLUSIONS: The patients presented with locally advanced disease. Chemoradiation is effective treatment for this group of patients and the majority avoid a permanent colostomy as they preserve anal sphincter function.
