在21年里(1955.1～1976.1)我们观察了7629例尸解病例,其中1186例为肺癌,通过这些例肺的组织切片,观察疤痕是否伴随肿瘤出现、疤痕的病因学及其他的重要所见,其中82例周边型肺癌均伴有疤痕。全部肺癌的15%是周边型。周边型肺癌的45%原发于疤痕,而且占所有肺癌的68%。疤痕癌的诊断标准,形态学特点,Friedrich 氏描述:①肺瘤上面的胸膜常常折叠和增厚;②在疤痕中常见炭末色素和胆固醇裂隙;③肿瘤中心区常有坏死带,它紧密围绕疤痕部,疤痕内部同样可见有炭末色素和胆固醇裂隙。本研究中发现肺癌的25%由腺癌组成,其中32%发生于周边部(59/82),15例是鳞状细胞癌
In 21 years (1955.1-1976.1), we observed 7629 cases of autopsy, of which 1186 were lung cancers. Through these lung tissue sections, we observed whether the scar was associated with tumor appearance, the etiology of scars, and other important observations. Of these, 82 cases of peripheral lung cancer were accompanied by scars. 15% of all lung cancers are peripheral types. 45% of peripheral lung cancers originate in scars and account for 68% of all lung cancers. Diagnostic criteria for keloid cancer, morphological features, and Friedrich’s description: 1 The pleura above the tumour often folds and thickens; 2 Common charcoal pigments and cholesterol fissures are found in the scar; 3 The necrotic zone often surrounds the tumour and it closely surrounds it. Scars, scars, and carbon-dioxide pigments and cholesterol crevices are also found inside the scars. In this study, 25% of lung cancers were found to consist of adenocarcinoma, of which 32% occurred in the peripheral (59/82) and 15 were squamous cell carcinomas.
