Pulmonary small cell undifferentiated carcinoma 139 cases X-ray analysis Shanxi Provincial Tumor Hospital (030013) Qi Shouren, Qi Shulin, Wen Shuwei, Zhang Xiaohua, Zhao Wanmiao Pulmonary small cell undifferentiated carcinoma accounts for about 15 to 25% of all lung cancers with the highest degree of malignancy, Biologic clinical features have a tendency of early metastasis and are sensitive to chemotherapy and radiotherapy, and timely diagnosis and treatment are expected to improve the efficacy. This article summarizes the X-ray findings and pathological basis analysis of 139 cases of small cell undifferentiated carcinoma confirmed by histology in our hospital as follows. Clinical data The 139 cases of small cell undifferentiated carcinoma in this group were confirmed by histology. There were 132 males and 7 females. There were 28 cases aged 90 to 40 years, 80 cases 40 to 60 years old, and 31 cases over 60 years old. All cases had complete X-rays, clinical data, and pathological findings. The main clinical symptoms were cough in 134 cases, sputum in 87 cases, superficial lymph node enlargement in 31 cases, and superior vena cava syndrome in 24 cases. X-ray analysis of a central type: 1 hilar type 98 cases. According to the hilar or hilar degree, the masses along the long axis of the bronchus were clearly defined. The masses were round, oval or lobulated. The edges were clear or partially clear, ranging in size from 3×3 to 5×7 cm. With hilar and mediastinal lymph node enlargement in 79 cases, 15 cases of hilar masses and mediastinal lymph nodes were not easy to distinguish, and 9 cases were bilateral mediastinal lymph node enlargement. On the bronchial layer, the bronchus was narrow and evenly stenotic, and the well-defined extraluminal masses (66 cases) along the long axis of the involved bronchus were seen. No obstructive changes were observed in the lungs and they were characteristic. 2 airway obstruction (33 cases), X-ray see different degrees
