肺大细胞癌的X线诊断

本文报告27例肺大细胞癌的X线研究结果,全部病例均病理证实。男性24例,女性3例,男女之比为8:1。周围型比较多见,生长迅速,转移较早。中心型大细胞癌或发生纵隔与肺门淋巴结转移者,其X线表现类似胸内淋巴瘤。周围型肿块可以坏死形成空洞或发展成大的实质性肿块。本病X线诊断不难,使用适当的活检技术,70～90％的病例可以确诊。

X-Ray Diagnosis of Large Cell Carcinoma of the Lung

A retrospective roentgenographic analysis was made of 27 patients with pathologic diagnosis of large cell carcinoma of the lung. This tumor occurs predominantly in males, with a ratio of 8 to 1. Large cell carcinoma tends to be more peripheral than the other types, but may be central. The rate of growth is rapid; lymphogenous metastasis occurs early. The central type, with or without metastasis, may resemble mediastinal lymphosarcoma. The peripheral type of the tumor may undergo necrosis to form cavities or become very large parenchymal mass. There is usually very little difficulty in arriving at the diagnosis of pulmonary carcinoma and 70~90 percent of large cell bronchogenic carcinoma can be diagnosed ofter cytologic examination by experienced personnel using proper biopsy techniques.
