Background: Hematopoietic toxicity of high-dose carboplatin (HD-CBDCA) chemotherapy can be managed effectively with autologous blood cell support, but no conclusive data are available on its the neuro- and ototoxicity. Patients and methods: We determined the neuro- and ototoxicity of HD-CBDCA in 10 patients affected by advanced ovarian cancer. HD-CBDCA was delivered as 24-hour continous infusion or as 5-day schedules. Each patient underwent an extended clinical and instrumental neurological and otological evaluation before, during and after treatment. Results: After HD-CBDCA only I patient had a clinically-evident peripheral neuropathy, while 3 additional patients had only distal paresthesias. Neurophysiological examination evidenced mild, although diffuse, sensory nerve impairment. Motor nerve impairment war also occasionally observed All the sensory and motor pathological changes had a favorable course during the follow-up period. Ototoxicity was more severe than neurotoxicity and, in one case it was dose-limiting and audiologic impairment tended to remain constant also in the follow-up period. Conclusions: HD-CBDCA treatment can be tolerated by most of the patients, but careful monitoring of neuro- and, especially, ototoxicity should be planned

Abstract
Background: Hematopoietic toxicity of high-dose carboplatin (HD-CBDCA) chemotherapy can be managed effectively with autologous blood cell support, but no conclusive data are available on its the neuro- and ototoxicity. Patients and methods: We determined the neuro- and ototoxicity of HD-CBDCA in 10 patients affected by advanced ovarian cancer. HD-CBDCA was delivered as 24-hour continous infusion or as 5-day schedules. Each patient underwent an extended clinical and instrumental neurological and otological evaluation before, during and after treatment. Results: After HD-CBDCA only I patient had a clinically-evident peripheral neuropathy, while 3 additional patients had only distal paresthesias. Neurophysiological examination evidenced mild, although diffuse, sensory nerve impairment. Motor nerve impairment war also occasionally observed All the sensory and motor pathological changes had a favorable course during the follow-up period. Ototoxicity was more severe than neurotoxicity and, in one case it was dose-limiting and audiologic impairment tended to remain constant also in the follow-up period. Conclusions: HD-CBDCA treatment can be tolerated by most of the patients, but careful monitoring of neuro- and, especially, ototoxicity should be plannedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
