Nonsurgical management of esophageal adenocarcinoma.

BACKGROUND

The benefit of induction chemotherapy (IC) before chemoradiotherapy (CRT) for inoperable esophageal adenocarcinoma has not been established. To clarify toxicities and outcomes of combined modality treatment, we performed a retrospective review.

MATERIALS AND METHODS

Sixty-eight consecutive patients were identified. Fifty-one patients had CRT, 17 had radiotherapy (RT). Fifty-eight received IC before RT. IC consisted of 4 cycles of platinum and fluoropyrimidines followed by CRT 54 Gy with concurrent infusional 5-fluorouracil (5-FU) or capecitabine. Response to IC was assessed at 3 months and response to CRT at 3 months. Time to progression (TTP) and overall survival (OS) are reported.

RESULTS

Fifty-four patients were men and 14 were women, with median age 72 years (range, 42-87 years). There were 29 stage II, 33 stage III, 4 stage IVa, and 2 stage IVb tumors. The response 3 months after completion of treatment was 39.6%. No grade 4 toxicity was reported, but 10/58 patients had grade 3 toxicity from IC. The median TTP and OS from RT for the entire cohort was 12 months (95% confidence interval [CI], 7-18) and 16 months (95% CI, 5-27), respectively. The 1- and 2-year survival rates from diagnosis were 73% and 47%, respectively. There was no statistically significant difference in TTP or OS in patients who responded to IC compared with those who did not (median TTP 11 vs. 12 months, respectively; P = .8; median OS 15 vs. 14 months, respectively; P = .8).

CONCLUSION

The outcome in patients with adenocarcinoma of the esophagus after CRT is comparable to unselected surgical series. Response to IC is not always an indicator of eventual outcome.
