The purpose of this study was to define the histopathological characteristics of pulmonary neoplastic lesions, especially focusing on the origin of tumor cells, in urethane-treated Tg rasH2 mice. Bronchiolar-alveolar adenomas/adenocarcinomas were observed in the lungs from all of the urethane-treated animals. Immunohistochemically, these tumors showed an alveolar epithelial type II (AE2) cell p...

Currently, the surgical method remains leading in combined treatment of pulmonary metastases. This review provides modern information about prognostic criteria for (primary metastasectomy and repeated resections chemoperfusion lung (ILuP)) isolated metastatic lesions with various primary tumors. It is concluded that knowledge influence factors on overall survival will create basis drawing up an...

using complement fixation technique, serial serum samples from 15 patients undergoing surgical removal of malignant tumors were assayed for the presence of tumors antibodies against the cellular fractions of both normal and carcinomatous tissue. antibody responses against tumor associated antigens were detected in four cases. in all cases antibody activity was directed only against the supernat...
