Clinicopathological and biological assessment of lung cancers with pleural dissemination
2000
Abstract Background . This study provides the surgical outcome of lung cancer patients with pleural dissemination, with the assessment of the clinicopathological and biological prognostic factors. Methods . Forty-three patients who underwent operations were studied. Vascular endothelial growth factor (VEGF) and autocrine motility factor receptor (AMFR/gp78) expression was immunohistochemically evaluated. Results . In total, the overall 3 and 5-year survival rates were 31.4% and 13.1%, respectively. The patients who underwent the pleuropneumonectomy had a worse outcome than those who underwent limited operations (pleurectomy plus parenchymal resections were less than pneumonectomy). VEGF and AMFR/gp78 were highly expressed in primary tumors. Among the patients who underwent limited operations, pathological types other than adenocarcinoma and high expression of VEGF were significantly associated with a worse outcome. The pathological type was the only characteristic to retain a significant independent prognostic impact on overall survival. Conclusions . The results imply the validation of limited operation for lung cancer with pleural dissemination for the local control. High frequency of VEGF and AMFR/gp78 expression conform to the interpretation that patients with pleural dissemination have a high-risk of systemic disease.
