JOURNAL ARTICLE
[Long-term outcome of neoadjuvant radiochemotherapy followed by surgery for esophageal cancer: a single institution retrospective study of 102 patients].
PURPOSE AND OBJECTIVES: To report survival and morbidity of a large homogeneous cohort of patients with a locally advanced esophageal or cardia carcinoma and put in evidence predictive factors of locoregional control and survival.
PATIENTS AND METHODS: Hundred and two patients were treated at the university hospital of Tours between 1990 and 2010 and received neo-adjuvant chemoradiation therapy with external irradiation (40Gy-44Gy) and two courses of chemotherapy (5-fluoro-uracile and cisplatine). Esophagectomy associated with lymph node dissection was performed about ten weeks after the end of chemoradiation therapy.
RESULTS: The median follow-up was 22.4 months [6-185 months]. The overall survival rates at 2 and 5years were 53% and 27%, respectively. The median overall survival was estimated at 27months. The overall 2-year survival between patients "responders" and patients "non-responders" was 67% vs 26%, respectively (P<0.0001). In case of histological response, there was a benefit in terms of overall survival (P<0.0001), locoregional control (P<0.0036) and disease-free survival (P<0.001). Overall survival at 2years was 64% for ypN0 group vs 32% for ypN1 group (P<0.0001). The median survival was estimated at 37months against 15months in the absence of lymph node involvement (P<0.0001).
CONCLUSION: Our results in terms of survival, tolerance and morbidity and mortality were comparable to those in the literature. Complete histological response of lymph node was associated with an improvement of local control, disease-free survival and overall survival.
