Lung function tests, including spirometry, and pulmonary transfer factor for carbon monoxide (TLCO), serum angiotensin-converting enzyme (sACE), serum copper (sCU++) and serum procollagen III peptide (sPIIIP) were measured in 20 patients with metastatic testicular carcinoma, before and after treatment with cisplatin, bleomycin, vinblastine or etoposide.

Abstract
Lung function tests, including spirometry, and pulmonary transfer factor for carbon monoxide (TLCO), serum angiotensin-converting enzyme (sACE), serum copper (sCU++) and serum procollagen III peptide (sPIIIP) were measured in 20 patients with metastatic testicular carcinoma, before and after treatment with cisplatin, bleomycin, vinblastine or etoposide. A significant decrease of TLCO, total lung capacity and vital capacity was observed at the end of the treatment. No recovery of pulmonary function had taken place 2 yrs after the last dose of bleomycin. This result suggests that bleomycin-induced lung damage is not completely reversible. Serum angiotensin-converting enzyme, remained unmodified, whilst sPIIIP was found to be significantly increased at the end of chemotherapy, but normal 2 yrs after the completion of chemotherapy. Serum Cu++ showed a tendency to decline. No significant correlation was found between sACE, sCu++ and sPIIIP and lung function tests in the follow-up period. These results question the possibility that these markers could be useful indicators of bleomycin-induced lung damage.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
