Lung Cancer in West Sweden 1976-1985 A Study of trends and survival with special reference to surgical treatment
1996
We reviewed 3 285 consecutive cases of lung cancer diagnosed in West Sweden during the period 1976-1985. Data were collected from the regional cancer registry, the Swedish National Population Registry, and medical records. During the study period, the annual female/male ratio increased from 0.29 to 0.42. In females, there was an increase primarily in the incidence of tobacco-related morphologic tumour types (i.e. squamous and small cell lung cancers). In males, a moderate increase of adenocarcinomas was seen, although squamous cell cancer remained the most common tumour type. The overall 5-year survival rate was 8.3%. In 641 patients (20%) a surgical tumour resection was carried out. The 5-year survival rate following resection was 38%, and the probability of 10-year survival was estimated at 25%. In a multifactorial model including gender, age, histology, pTNM stage and extent of resection, pTNM stage and, to a lesser degree, age were statisticaUy significant independent predictors of postoperative survi...
