Abstract

Background

We hypothesized that the survival rate of patients undergoing R0 esophagectomy after induction chemotherapy or chemoradiotherapy for unresectable T4 esophageal cancer (URT4) would be similar to that of patients undergoing esophagectomy for immediately resectable esophageal cancer with no unfavorable prognostic factors (RNU).

Methods

Between April 2002 and June 2012, 87 of 283 patients with esophageal cancer who presented at the University Hospital of the Ryukyus were enrolled in this prospective cohort study. Tumors were classified as RNU and URT4 in 44 and 43 of the 87 patients, respectively. Outcomes of treatment for URT4 patients were compared with those of RNU patients.

Results

The R0 resection rate (61 %) and in-hospital mortality rate (20 %) of URT4 patients were significantly poorer than those of RNU patients (98 and 2.3 %, respectively), although the morbidity rate was similar in the two groups (63 and 52 %, respectively). The 5-year survival rate (35 %) of URT4 patients was significantly poorer than that of RNU patients (67 %) in the intention-to-treat analysis. However, no significant difference was noted between the two survival curves for cases of R0 resection (5-year survival rate, 60 % vs. 69 %). Multivariate analysis revealed R status as the only significant independent prognostic factor for URT4 patients (P < 0.001; hazard ratio = 8.279).

Conclusions

Satisfactory survival rates can be achieved if R0 resection is performed after induction treatment in patients with T4 esophageal cancer, although secondary radical esophagectomy is associated with a higher risk of in-hospital mortality.
