Abstract

Background and objectives: Esophageal cancer incidence is gradually increasing worldwide. Studies have looked at the pathological stage rather than clinical stage as predictor of survival. We looked at patients with complete pathological response to compare their survival outcomes to those who had residual disease after neoadjuvant treatment. Materials and methods: All patients with esophageal cancer who underwent neoadjuvant treatment followed by resection at our institute were retrospectively reviewed. Overall survival and disease free survival were calculated for patients with complete pathological response and compared to those with residual disease using log rank test. Results: Mean age of our patients was 51.08 years with standard deviation of 10.17 years. 39% belong to stage IIa while 5% belong to Stage IIb. 56% were Stage III. Final histopathological stage was recorded and both disease free and overall survival were calculated. 45% of our patients had complete pathological response. Patients with complete pathological response had mean survival of 62.73 months±17.02 compared to 41.42 months for patients who had residual disease. 5 year disease free survival was 58%. Conclusion: Complete Pathological response significantly improves overall and disease free survival. It is also the predictor of long term survival. © 2014 Surgical Associates Ltd.
