Tumor cell type versus staging in the prognosis of carcinoma of the lung.

摘要: From this and other studies, it is clear that the determination of tumor cell type dependent on cellular architectural patterns which are fraught with considerable interobserver even intraobserver variations. Even though semiobjective at best, previous reports have sought to determine prognosis solely basis or subtype while studies made attempts define disease based less precise terms. In seeking an answer question more important for lung cancer, TNM stage, findings reported herein support hypothesis stage single most factor survival. This conclusion substantiated by following observations: 1. When stratified no significant differences can be determined in survival according type. 2. There a minor difference (not statistically significant) when considering resected I tumors (67 99) terms adenocarcinomas had 38 percent 5 years versus squamous carcinomas 23 years. The numbers cases study were not sufficiently large comment possible between surgically small carcinomas. 3. staging highly predictor patients cancer. significance remains if data diagnosis. These conclusions apply total group 124 patients, also subgroup 99 patients. Many attempted carcinoma without regard its stage. Consequently, comparison from various institutions difficult. We believe only allows reasonable obtained different institutions, but also, affords useful accurate means assessing extent prognosis.
