Beschreibung: 92 Background: Docetaxel (DOC) represents the treatment of choice in the first line treatment for patients (pts) with castration-resistant prostate cancer (CRPC). However, when CRPC is diagnosed in pts age 80 or older, the fear of high toxicity degree usually limits chemotherapy use due to both pts frailty and several comorbidities occurrence. The present retrospective study is aimed to assess the clinical outcomes in this very elderly CRPC population. Methods: In this multicentric retrospective study, after Ethical Committee approval, we have reviewed the clinical records of all pts age 80 and older CRPC pts from participating institutions, treated with DOC in clinical practice, recording the pre- and post-DOC clinical history, the DOC treatment details and outcomes. Results: To date we collected a consecutive series of 115 pts from 28 Italian hospitals. The median age was 82 (range 80 to 90). The median baseline prostate-specific antigen (PSA) was 92 ng/ml (range 3 to 2,981); 83% of the pts had bone metastases, while nodal, lung and liver metastases were observed in 39%, 9%, and 8% of the pts, respectively. Median Cumulative Illness Rating Scale score was 3 (range 0 to 11), median Activity Daily Living index score was 0 (range 0 to 5), median Instrumental Activities of Daily Living score was 0 (range 0 to 5). The DOC was administered on 3 week or weekly schedule basis (43%/57%). A PSA reduction greater than 50% was observed in 55% of the pts; an objective response was observed in 15% of the 60 pts who underwent a radiological re-evaluation at the treatment end. Grade 3-4 toxicities were: anemia (2%), neutropenia (10%) , thrombocytopenia (2%), fatigue (10%), diarrhea (4%), nausea (2%), renal (2%), and febrile neutropenia (2%). The median progression-free survival (PFS) and overall survival (OS )were 7 months and 20 months, while the 1 year PFS and OS rates were 21.2% and 71.5%, respectively. Conclusions: This data suggests that selected very older (age 80 and older) CRPC pts may received DOC with a good toxicity profile. In this pts population the treatment, both on 3 week or weekly schedule, is able to produce survival outcomes comparable to pivotal trials (18 months).
