MuItimodality treatment improves esophageal squamous cell carcinoma (ESCC) prognosis, however the most optimal treatment still remains controversial. In 213 ESCC patients who had operation at Kitasato University Hospital between 1996 and 2007, prognosis was evaluated in terms of cStage and adjuvant therapy. Survival outcome of with the 62 cStage I ESCC were excellent (2 recurrences) with infrequent postoperative treatment (Adj). Of 129 ESCC patients with cStage II/III, 45 patients including suspicious cT4 (cT3.5) were given neoadjuvant therapy (Neo), and pStage 0/I patients showed excellent prognosis. Of 84 cStage II/III patients not given Neo, 67 (79.8%) underwent R0 esophagectomy, among whom 20 cases had pN0 (pStage II/IIa) with 3 recurrences (15%) despite infrequent Adj. On the other hand, among the 45 cStage II/III patients with Neo, 8 pStage IIa patients exhibited poor prognosis with 5 recurrences (62.5%) as well as pStage III/IV. In pStage IIb ESCC, cStage IIa showed poorer prognosis than cStage I/IIb (P = 0.0072). Among the 21 cStage IV ESCC patients, 5 long-term survivors were experienced by multimodality treatments. Both cStage and Neo greatly affect ESCC prognosis irrespective of identical pStage, which must be allowed for in order to determine therapeutic strategy against ESCC.
