    Abstract:
    PURPOSE: Currently, preoperative chemoradiotherapy followed by surgery is the only promising strategy for patients with T4 esophageal cancer. This study retrospectively analyzed the prognostic factors in patients with curatively resected cancer after chemoradiotherapy. PATIENTS AND METHODS: Between September 1989 and December 2003, 42 patients with T4 esophageal cancer received preoperative chemoradiotherapy (CRT) followed by curative surgery. Chemotherapy consisted of 5-fluorouracil/cisplatin (FP) or 5-fluorouracil/adriamycin/cisplatin (FAP). A total dose of 40 Gy of radiation was delivered concurrently. Surgery was scheduled 4 weeks after the completion of CRT. The treatment response was categorized using general criteria. Toxicities of the CRT were assessed according to National Cancer Institute of Common Toxicity Criteria (NCI-CTC). Univariate and multivariate analyses were performed to identify significant prognostic clinicopathological factors. RESULTS: The overall survival rate was 38.4% at 5 years. The toxic grade for leukopenia (grade 0-2/3-4) and pathological effect (grade 3/1-2) were significantly different by univariate analysis (P = 0.03 and 0.05, respectively). Multivariate analysis identified the toxic grade for leukopenia as the only significant and independent determinant of prognosis (P = 0.05). CONCLUSION: In patients with T4 esophageal cancer who receive CRT followed by curatively resection, myelogenic chemotoxicity is a significant prognostic factor.
