肺癌肿瘤内新生血管征象的研究及其临床意义

STUDIES ON SIGN OF NEOVASCULARITY WITHIN THE LUNG CANCER AND ITS CLINICAL SIGNIFICANCE

本文分析了68例原发性肺癌和2例肺转移癌病例的支气管动脉造影(BAG)中重要征象之一的肿瘤内新生血管。瘤内新生血管的多少与肿瘤的发生部位及大小有关。中心型肺癌瘤块与周围型之瘤块距肺门近者以多血管型者居多,小肿块病例中比肿块大的病例中多血管型多。而各组织类型中均以多血管型病例为多,但差别不明显,这与文献报道鳞癌少血管型者多相反。通过本组病例我们认为肺癌内新生血管对鉴别诊断,指导治疗及估测疗效均有重要意义。

The neovascularity within the tumor, one of the important signs of bronchial arteriography (BAG) in 68 cases with primary bronchogenic carcinoma and 2 cases with metastatic tumors was analysed. There was a close relationship between the number of developing vessels and the location and size of the tumor. The more the lesions were nearing the hilum, the more vessels would be . Much more vascularity was observed in smaller masses, than in the larger ones . No difference was seen in tumors of various histotypes ; the majority of cases is polyvascular and only a few oligovas-cular. This result is opposite to reports in the literature that the majority of squamous cell cancer was oligovascular.Anyhow, the neovascularity within the tumor is significant in differential diagnosis, treatment and evaluation of the therapeutic effect of tumors.
