Abstract

Objective: Neoadjuvant chemotherapy with 5-fluorouracil plus cisplatin and subsequent esophagectomy with two- to three-field lymphadenectomy is a standard treatment for patients with clinical stage II/III squamous cell carcinoma (SCC) of the esophagus. This study investigates the prognostic factors for patients who received neoadjuvant chemotherapy. Methods: Of 164 patients assigned to receive neoadjuvant chemotherapy in the JCOG9907 trial, multivariate analyses were performed for 159 and 149 patients to evaluate the preoperative and the combined preoperative and postoperative prognostic factors, respectively. Results: The multivariate analyses using preoperative factors showed that clinical stage T3 [vs. cT1-2; hazard ratio (HR) 3.60, p = 0.0007] and serum albumin (Alb) <4.0 g/dl (vs. ≥4.0 g/dl; HR 2.29, p = 0.0005) were associated with a poor prognosis. Four independent prognostic factors were identified by multivariate analysis of both preoperative and postoperative factors: pathological curability B (pB; R0 with stage IV or pD < pN) or pC [microscopic or macroscopic residual tumor (R1/R2)] [vs. pA (R0); HR 1.93, p = 0.015], pathological stage N1 (vs. pN0; HR 3.86, p = 0.0012), cT3 (vs. cT1-2; HR 2.80, p = 0.0073), and serum Alb <4.0 g/dl (vs. ≥4.0 g/dl; HR 2.03, p = 0.0069). Conclusions: Preoperative cT stage, Alb, and postoperative pathological findings are independent prognostic factors for patients undergoing neoadjuvant chemotherapy for advanced thoracic esophageal SCC. This analysis may aid in stratification according to individual patient risk.
