PURPOSE: This study reports the results of the use of preoperative concurrent radiochemotherapy (CRCT) for the treatment of locoregionally advanced esophageal cancer.
MATERIALS AND METHODS
From 1998 through 2005, 61 patients with intrathoracic esophageal cancer at stages II-IVB (without distant organ metastasis and presumed to be respectable) received preoperative CRCT. CRCT consisted of radiotherapy (45 Gy /25 fractions /5 weeks) and FP chemotherapy (5-FU 1 g/m2/day, days 1-4 and 29-32, Cisplatin 60 mg/m2/day, days 1 and 29). An esophagectomy was planned in 4~6 weeks after the completion of CRCT.
RESULTS
There were two treatment-related deaths. Among the 61 patients, 53 patients underwent surgery and 17 patients achieved a pathological complete response (pCR). The overall survival (OS) rates of all 61 patients at 2 and 5 years were 59.0% and 38.0%, respectively. The rates of OS and disease-free survival (DFS) of the surgically resected patients at 2 and 5 years were 61.6%, 40.1% and 53.3%, 41.8%, respectively. By univariate analysis, achieviement of pCR and a clinically uninvolved distant lymph node (cM0) were favorable prognostic factors for OS and DFS. There were 27 patients that experienced a relapse-a locoregional relapse occurred in 5 patients, a distant metastasis occurred in 12 patients and combined failure occurred in 10 patients.
CONCLUSION
The results of the current study are favorable. pCR and an uninvolved distant lymph node were found to be favorable prognostic factors.
