[Multiple neoplasms].

This paper describes observation on multiple carcinomas, with emphasis on double carcinomas of the lungs and other organs. The paper presents four cases of multiple neoplasmas and goes on to discuss eventual etiopathogenesis of multiple malignancies. Of the four cases presented in this paper, three cover double carcinoma of the throat and lungs, and in the fourth, double carcinoma of the lung and bladder.

[Post-radiation fibrosis of the lung].

The lung fibrosis after irradiation of lung cancer is described in this paper, as well as pathologic physiology, clinical signs and symptoms, and radiographic changes. Carefully treatment planning using CT scans, simulator and computer planning system is the only way to prevent excessive irradiation of the lung and correspondent lung fibrosis.

[Radiotherapy in the treatment of bronchial carcinoma].

Aim of this paper is to give the role of the radiotherapy, alone or in combination with other treatment modalities, in treatment of lung cancer. Conventional external radiotherapy is described, as well as some recent techniques: after loading brachytherapy and laser therapy. We concluded that radiotherapy has an important role in treatment of lung cancer, mostly as palliation, and in some selected cases as a treatment with curative intent.
