ABSTRACT

Objective To investigate the expression of stathmin and evaluate its influence to anti-microtubule adjuvant chemotherapy in non-small-cell lung cancer(NSCLC).Methods The clinical data and survival status of 78 NSCLC patients were collected,and their paraffin-embedded tissue were detected immunohistochemically with a rabbit anti-human stathmin polyclonal antibody.The clinical significance of stathmin expression and its influence to overall survival rate were analyzed statistically between patients who received paclitaxel or vinblastine adjuvant chemotherapy.Results The positive expression of stathmin could only be observed in the cytoplasm of cancer cells.Among 78 patients,40 (51.3 % ) patients were stained stathmin-positive.The positive rate of stathmin was significantly higher in male than female,in central type than peripheral type,in pleura-involved than non-involved,and in dead patients than survival patients ( P < 0.05 ),but showed no significant differences in patients with different age,differentiated grade,pathological type,clinical stage,or lymph-node metastasis status.The expression of stathmin had a significant influence to overall survival rate(x2 =4.348,P <0.05 ),and those stathmin-negative patients showed a longer survival time.In stathmin-negative patients,those who received adjuvant chemotherapy with vinblastine exhibited a shorter survival time than those with paclitaxel,but the P =0.06.In stathmin-positive patients,the survival rate or time showed no difference between groups with paclitaxel and vinblastine.The differentiated grade,metastasis to lymph node and expression of stathmin were independent risk factors influencing survival rate.The positive expression of stathmin could only be observed in the cytoplasm of cancer cells.Among 78 patients,40 (51.3 % )patients were stained stathminpositive.The positive rate of stathmin was significantly higher in male than female,in central type than peripheral type,in pleura-involved than non-involved,and in dead patients than survival patients ( P < 0.05 ),but showed no significant differences in patients with different age,differentiated grade,pathological type,clinical stage,or lymph-node metastasis status.The expression of stathmin had a significant influence to overall survival rate(x2 =4.348,P < 0.05 ),and those stathmin-negative patients showed a longer survival time.In stathmin-negative patients,those who received adjuvant chemotherapy with vinblastine exhibited a shorter survival time than those with paclitaxel,but the P =0.06.In stathmin-positive patients,the survival rate or time showed no difference between groups with paclitaxel and vinblastine.The differentiated grade,metastasis to lymph node and expression of stathmin were independent risk factors influencing survival rate.Conclusion Our study suggested that the detection of stathmin in resected NSCLC tumor tissues may be helpful for prediction of prognosis,but helpless for making a choice between paclitaxel and vinblastine.NSCLC patients with stathmin-negative,no metastasis to lymph node or good-differentiated grade may have a better prognosis.

ABSTRACT

<p><b>BACKGROUND</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSIONS</b>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.</p>
