In the 48-month survival analysis of 76 evaluable pyriform sinus carcinoma cases, nodal stage and size played the most significant prognosis-affecting roles. N3 stage and node greater than 3 cm decreased the survival fourfold and threefold, respectively, at statistically significant levels. The difference between the 35 per cent preoperative radiation therapy and 3 per cent radical radiation therapy cumulative 48-mouth survivals was significant at p less than 0.01. Complication rates were 6 per cent with radical radiation, 35 per cent with preoperative radiation and 43 per cent with curative surgery.
在对76例可评估的梨状窦癌病例进行的48个月生存分析中，淋巴结分期和大小对预后的影响最为显著。N3期和直径大于3 cm的淋巴结分别使生存率降低了四倍和三倍，差异具有统计学意义。术前放疗35%与根治性放疗3%的48个月累积生存率差异显著，p值小于0.01。根治性放疗的并发症发生率为6%，术前放疗为35%，根治性手术为43%。
