RESUMO

Lung cancer is the leading cause of cancer mortality in the occident. In spite of the advances in lung cancer diagnosis and treatment, little has changed with respect to survival expectations. Molecular biology and oncogenes show a new way regarding the lung cancer subject. Seventy-eight patients with non-small cell lung cancer, who underwent thoracotomy for lung resection and survived more than one month afier this procedure were reviewed. Immunohistochemical staining for c-erb-2, Ki-67 and b-HCG was performed on dewaxed, formalin-fixed, paraffin sections of resected lung tumor utilizing microwave antigen retrieval. Mitosis was counted. The median survival was 25.9 months. At the time the patients underwent the surgical procedure 3.8% were in stage I-A, 20.5% in stage I-B, 3.8% in stage lI-A, 35.9% in stage II -B and 35.9% in stage III-A. Lobectomy was performed in 46.2% of the patients and pneumectomy was performed m 42.3% percent of them. The pathologic findings were: epidermoid carcinoma with 59% cases, adenocarcmoma with 34.6% cases, undifferentiated carcinoma with 5.1% cases and adenosquamous carcmoma in one patient. C-erbB-2 immunohistochemical staining was more frequently identified in the advanced clinical stage of the disease. C-erbB-2, Ki-67, mitosis and b-HCG were not important in Kaplan-Meier survival curves. Only stage group and histological type were statistically important in the same test.
