Purpose: Currently, preoperative chemoradiotherapy followed by surgery is the only promising strategy for patients with T4 esophageal cancer. 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 (CRT) followed by curative surgery. Chemotherapy consisted of 5-fluorouracil/cisplatin (FP) or 5-fluorouracil/adriamycin/ (FAP). A total dose of 40 Gy of radiation was delivered concurrently. Surgery was scheduled 4 weeks after the completion of CRT. The response was categorized using general criteria. Toxicities of the CRT were assessed according to National Cancer Institute of Common 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) significantly different by univariate analysis (P = 0.03 and 0.05, respectively). Multivariate analysis identified the toxic grade for leukopenia 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 factor.
