Ionic currents in carotid body type I cells isolated from normoxic and chronically hypoxic adult rats

2115 cases of chest neoplasms were registered during the first six months of 1995 in Pulmonary Outpatient Departments in Poland. In 865 (40.8%) patients squamous cell cancer was diagnosed, in 344 (16.2%)--small cell lung cancer, in 174 (8.2%)--adenocarcinoma, in 107 (5%) other types of lung cancer and in 5.6% of cases--lung cancer with undefined histology. Predominated subjects aged from 60 to 69 years (43.5%). Lung cancer under 50 years of age was observed significantly more often among women (25.8%) than among men (13.5%). Moreover adenocarcinoma was much more frequent among women than men and significantly more cases of lung cancer were recorded in nonsmoking women. Diagnosis was established during the first 4 weeks in 38.9% of patients but 23.6% of patients have waited for it more than 39 weeks. Surgical treatment was advised in 16.9% of subjects, radiotherapy in 14.3% and 26.4% of patients underwent chemotherapy. Treatment analysis was presented according histological type of lung cancer. Occupation, performance status, clinical stage of the disease, prevalence of cancer in patients families were also analysed.
