500 patients with proven bronchial cancer have been classified according to the TNM-system in a retrospective study. By classifying symptoms, clinical and technical findings into the classes of the TNM-system the frequency of individual symptoms and findings at different stages of bronchial cancer was examined statistically. The majority of the investigated parameters demonstrated an increasing frequency with advancing T-classes.
在一项回顾性研究中，500名经证实患有支气管癌的患者已根据TNM系统进行了分类。通过将症状、临床和技术检查结果归类到TNM系统的各个类别中，对支气管癌不同阶段的个体症状和检查结果的出现频率进行了统计学检查。大多数被调查参数显示，随着T分期的进展，出现频率增加。
