ABSTRACT
BACKGROUND:
At present, it has been known that the bronchogenic artery participates in the blood supply of primary bronchogenic carcinoma, but there is controversy about the blood supply from pulmonary artery in primary bronchogenic carcinoma. The aim of this study is to assess the relationship between the blood supply from pulmonary artery and pathological characteristis of patients with primary bronchogenic carcinoma.METHODS:
The pulmonary arteries in 43 surgical samples of bronchogenic carcinoma were marked, then the iopromide was used to selective pulmonary arteriography in digital subtraction angiography (DSA). The relationship between tumor with blood supply from pulmonary artery and the pathologic characteristics was observed.RESULTS:
There were 34 samples with blood supply from pulmonary artery ( 79.07%) , and 9 samples without blood supply from pulmonary artery (20.93%). The development rate of peripheral lung cancer (100.00%) was significantly higher than that of central lung cancer (64.00%) (P < 0.01) . The development rate of squamous cell carcinoma (91.30%) was remarkably higher than that of adenocarcinoma (61.11%) (P < 0.05). The development rate of poorly differentiated lung cancer (95.00%) was remarkably higher than that of well and moderately differentiated lung cancer (65.22%) (P < 0.05). There was a positive relationship between the tumor size and the development rate (P < 0.05).CONCLUSIONS:
In primary bronchogenic carcinoma, the pulmonary artery blood supply exists in most of tumors. There is relationship between the blood supply from pulmonary artery and general type, histopathology, cell differentiation and tumor size of lung cancer. The blood supply from pulmonary artery doesn't relate to tumor stage.
