Titel:: Long-term outcomes of trimodality treatment for squamous cell carcinoma of the esophagus with cisplatin and/or 5-FU: more than 20 years' experience at a single institution.
Abstract:: The purpose of this article is to report the outcome of neoadjuvant radiochemotherapy (N-RCT) + surgery in patients with squamous cell carcinoma of the esophagus at a single institution.We retrospectively reviewed data from patients who were referred to our department for N-RCT. From 1988-2011, 103 patients were treated with N-RCT with cisplatin and/or 5-fluorouracil (5-FU). Group 1: (n = 55) from 1988-2006 with 39.6-40 Gy and 5-FU with (n = 17) or without cisplatin (n = 38). Group 2: from 2003-2010 with 44-45 Gy and 5-FU with (n = 40) or without cisplatin (n = 8). All patients underwent radical resection with reconstruction according to tumor location and 2-field lymph node dissection. The degree of histomorphologic regression was defined as grade 1a (pCR, 0 % residual tumor), grade 1b (pSTR, < 10 % residual tumor), grade 2 (10-50 % residual tumor), and grade 3 (> 50 % residual tumor).Median follow-up time from the start of N-RCT was 100 months (range 2-213 months). The median overall survival (OS) for the whole cohort was 42 months and the 5-year OS was 45 ± 5 %. In the multivariate analysis, worse ECOG performance status (p < 0.001), weight loss > 10 % before the start of the N-RCT (p = 0.025), higher pT category (p = 0.001), and grade 2/3 pathologic remission (p < 0.001) were significantly associated with a poor OS. PCR and pSTR rates for group 1 were 36 % and 18 % compared to 53 % and 22 % for group 2 (p = 0.011). There was a tendency for a better outcome in group 2 patients without statistical significance. The 5-year OS, disease-free survival and recurrent-free survival were 36 ± 7 %, 35 ± 6, and 36 ± 7 % for group 1 and 55 ± 7, 49 ± 7, and 53 ± 7 in group 2 (p = 0.117, p = 0.124, and p = 0.087). There was no significant difference between the two groups considering the postoperative morbidity and mortality.Higher radiation doses and more use of simultaneous cisplatin lead to higher pathologic response rates to N-RCT and may be associated with better survival outcomes. Prospective controlled trials are needed to assess the true value of intensified N-RCT regimens.
