PURPOSE: Long-term toxicity after cancer treatment has gained increasing clinical attention. We evaluated pulmonary function in long-term survivors of testicular cancer (TC). PATIENTS AND METHODS: The pulmonary function of 1,049 TC survivors treated during 1980 to 1994 at three university hospitals in Norway was assessed by spirometry and a questionnaire (1998 to 2002). The patients were categorized into five treatment groups, as follows: surgery only (n = 202); radiotherapy only (n = 449); chemotherapy (cisplatin 850 mg [higher-dose group]; n = 62); and chemotherapy and pulmonary surgery (cis/pulmsurg; n = 30). Spirometry variables included forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1). Actual values and percentages of predicted normal values (FVC%pred and FEV1%pred, respectively) are reported. Restrictive lung disease was defined as FEV1/FVC > or = 70% and FVC%pred less than 80%. RESULTS: Median observation time was 11.2 years (range, 5 to 21 years). Compared with the surgery group, the higher-dose or cis/pulmsurg groups had considerably lower age-adjusted FVC (higher-dose: beta = -.37; P = .001; cis/pulmsurg: beta = -.58; P
