ABSTRACT

BACKGROUND: Little is known about the management of squamous cell carcinoma of the anal canal and its recurrence at a population level. The aim of this study was to draw a picture of management, recurrence and survival in squamous cell carcinoma of the anal canal. MATERIAL AND METHODS: The 5-year probability of recurrences was estimated using the cumulative incidence function to consider competing risks of death. Net survival was estimated and a multivariate survival analysis was performed. The study was conducted using data of the Burgundy Digestive Cancer Registry. Overall, 273 squamous cell carcinomas of the anal canal registered between 1998 and 2014 were considered. RESULTS: Overall, 80% of patients were treated with curative intent. Of these, 61% received chemoradiotherapy, 35% received radiotherapy and 4% received abdominoperineal resection alone. After these treatments, for cure the 5-year cumulative recurrence rate was 27% overall; it was 20% after chemoradiotherapy and 38% after radiotherapy. Five-year net survival was 71% overall; it was 81% after chemoradiotherapy and 55% after radiotherapy. CONCLUSIONS AND RELEVANCE: Chemoradiotherapy was highly effective in routine practice. We confirm that it is difficult to distinguish between persistent active disease and local inflammation due to radiotherapy. Squamous cell carcinoma of the anal canal recurrences remains a substantial problem, highlighting the interest of prolonged surveillance. Aggressive management of recurrences may be beneficial.

ABSTRACT

BACKGROUND: The optimal treatment for oesophageal cancer is a matter of debate. The aim of this study was to describe patterns of care and survival in a well-defined population for squamous cell carcinoma (SCC) and adenocarcinoma (AC) of the oesophagus. DESIGN: Data were provided by the Digestive Cancer Registry of Burgundy (France). Recurrence, excess mortality and net survival were calculated. RESULTS: Among non-metastatic patients, the proportion of patients resected for cure decreased between 2004 and 2013 from 16% to 9% for SCC and 48% to 22% for AC. The administration of chemoradiation increased from 45 to 53% for SCC and 21 to 30% for AC. A complete clinical response to chemoradiation was reported in 40% of the patients. Five-year net survival did not vary according to histology. It was 55% in the selected group of patients resected for cure, 44% in patients treated with chemoradiation with a complete clinical response. In multivariate analysis, treatment modality only was associated with survival. In metastatic patients, 3-year net survival was 14% for those treated with chemoradiation. CONCLUSION: Chemoradiation has become the most frequently administered treatment. Cancelling or postponing surgery after chemoradiation with complete response should be assessed by a randomized clinical trial.
