Preoperative chemotherapy and preoperative chemoradiation, both improve survival for locally advanced esophageal cancer proven in randomized trials and metanalysis. Limited data are available comparing these preoperative therapies especially in non-gastroesophageal junction squamous cell cancer of esophagus. In this retrospective analysis, 69 eligible patients of locally advanced esophageal cancer, who underwent preoperative chemoradiation followed by surgery or chemotherapy followed by surgery at our center were analyzed. The end points of study were overall survival, disease free survival, and histopathological response. Three weekly paclitaxel and carboplatin was used as neoadjuvant chemotherapy and weekly paclitaxel and carboplatin were used with radiation as per standard protocol. Median follow-up time was 35 months for surviving patients. Median overall survival was 44 months (95% CI 27.2–62.7) in chemoradiation group and it was not reached in the chemotherapy arm (p-value −0.832). The median disease-free survival for patients who underwent preoperative chemoradiation was 41 months and 34 months in preoperative chemotherapy group (p-value −0.812). Seven of 41 patients (17.1%) in chemoradiation group were circumferential resection margin (CRM) positive as compared with six of 28 (21.4%) in chemotherapy group (p = 0.650). A pathological complete response was seen in 13 (31.7%) patients in chemoradiation group and seven (21.4) patients in chemotherapy group. There was no survival advantage for preoperative chemoradiotherapy compared with preoperative chemotherapy in patients with predominant esophageal squamous cell carcinoma of locally advanced esophageal cancer. Despite the non-significant improvement from preoperative chemoradiation with respect to CRM positivity and pathological complete response rates, there was no difference in overall survival or disease-free survival.
