    BackgroundDue to the poor prognosis of locally advanced oesophageal cancer, predictive markers are warranted to better select patients who may benefit from multimodal therapy.Patients And MethodsPatients with oesophageal cancer from two multicentric prospective trials were selected for having received radiochemotherapy followed by macroscopic complete tumour resection. Several pretreatment and treatment related factors were retrospectively analysed for their ability to serve as predictive markers.ResultsOverall 107 patients with squamous cell carcinomas stage T3-4 N and M0 were included in the analysis. All of them had complete preoperative radiochemotherapy. Microscopic (n=96) or macroscopic (N=11) complete resection was achieved by transthoracic oesophagectomy. The median follow-up time exceeded 6 years. Local progression free and overall survival were significantly hampered in patients with residual tumour in their resected specimen (n=76) compared with patients who showed a pathohistologic complete tumour remission (n=31) (overall survival rate at 3 years 25.2% versus 65.6%; hazard ratio (HR)=3.50 (95%-confidence interval (CI) 1.91-6.44); p<0.0001). A multivariable analysis proved both resection status and pathohistologic results to be independent acting predictive factors for local progression free and overall survival after preoperative radiochemotherapy with surgery.ConclusionsFrom our study it appears that the pathohistologic results can be a valuable surrogate marker for predicting long term survival and local tumour control in patients with locally advanced squamous cell carcinoma (SCC) of the oesophagus after preoperative radiochemotherapy and surgery. Moreover, even after intensive preoperative therapy a complete tumour resection seems to be an important precondition for long term survival.Copyright © 2012 Elsevier Ltd. All rights reserved.
