Lung cancer is the most frequent type of malignant disease among men. It is also the leading cause of cancer deaths among both men and women. Annually, there are over 8 million new cases and over one million deaths worldwide due to lung cancer. Smoking is a contributing factor in about 90% of men and 78% of women in these cases, while other cases are believed to be caused by occupational or environmental exposure to various noxious agents, pulmonary fibrosis and genetic factors.<\/p>\n
From 1995 to 1998, the incidence of lung cancer in Slovenia among men decreased from 88.3 to 82 per 100,000; there was also a decrease in the percentage of lung cancer among all malignant diseases, from 22 to 19%. During the same period, the incidence of lung cancer among women increased to 19 in 100,000, representing 5% of all malignant diseases. Limited lung cancer, locally spread lung cancer, lung cancer with distant metastases and undetermined stages of lung cancer represented 25%, 38%, 34% and 3% of cases, respectively.<\/p>\n
In 1998, 82.9% of lung cancer cases presented histologically as non-small cell lung cancer. Small-cell lung cancer with a very unfavorable prognosis was found in the remaining 17.1%. In the last two decades, the incidence of adenocarcinoma has increased. The overall 5-year survival rate was 8% for men and 10% for women, but over 60% for stage I of the disease. The latest classification of lung tumors distinguished other unfavorable histological types and subtypes of non-small cell lung cancer, such as pleomorphic and combined large cell neuroendocrine cancer, which represent about 10% of cases. Synchronous and metachronous double primary lung tumors were detected in 8.4% of cases in the lungs and at other locations in 11%, and triple primary tumors in 0.8% of cases. Various tumor and non-tumor synchronous multiple pathological changes in the lungs were found in 18% of cases.<\/p>\n","protected":false},"excerpt":{"rendered":"
