RESUMO
The paper presents our experience with application of a diagnostic procedure which enhanced information potential of endoscopy. Its efficiency increased due to use of an algorithm which included several stages carried out during an endoscopic procedure: routine bronchoscopy, spectroscopy in light (400-700 nm), autofluorescence spectroscopy including nearest infrared spectrum (720-800 nm). During treatment, the latter registered the dynamics of glow intensity ratios in the red (600-680 nm) and green (500-550 nm) spectra. The efficacy of our method was determinated by the precise delineation of the involvement area and its changes in the course of treatment which matched final analysis data.

The authors give a morphological and immunohistochemical description of epitheliod hemangioendothelioma of the lung in two women aged 62 and 74 years. Evident neovascularization capacity, a significant tumor cell intracytoplasmic lumen frequently packed with red blood cells, and positive immunohistochemical reactions to endothelial antigens are of prime importance in making its diagnosis.

An evaluation of the literature and our own experience with surgical and combined treatment of lung cancer complicated by postoperative pleural empyema established the following incidence rates in 2.4% of patients: postpneumonectomy (4.2%), particularly on the side (57.4%), and in tumor stage III cases (70.6%). Bronchal stump failure (89.7%) was the main cause of postoperative pleural empyema while the risk doubled (4.5-6.0%; p < or = 0.05) after neoadjuvant therapy. Both immediate and end results were worse in postoperative pleural empyema than in similar uncomplicated cases: 12 month survival--43.8% vs. 71.1%; 3-year--18.8-36.8%; 5-year--10.4-26.3%. Also, postoperative pleural empyema patients stayed in hospital longer.
