All patients have received a median of four and half cycles ( range , 1 - 10 ) of 3-week ( 60 - 75 mg/m2 ) docetaxel regimens and 5 mg prednisone twice per day .
Efficacy and safety of docetaxel and prednisolone chemotherapy in very elderly men with metastatic castration-resistant prostate cancer (mCRPC) in real world: a single institute experience. Prostate cancer is the most common type of malignancy in elderly men. Although elderly patients are commonly encountered in clinical practice, few studies have focused on the value of chemotherapy in elderly patients. In this study, we reviewed the use of docetaxel with prednisolone in elderly men (aged ≥80 years) with metastatic castration-resistant prostate cancer (mCRPC) at Ningbo First Hospital with a focus on efficacy and toxicity. ### methods A retrospective study including a series of men aged ≥80 years with mCRPC and received docetaxel plus prednisone chemotherapy between August 2011 and May 2019. All these cases were selected from the Ningbo First Hospital prostate cancer database located in Zhejiang Province, China. ### results Sixteen patients were identified, with a mean age of 82 years (range, 80 to 87 years). All patients have received a median of four and half cycles ( range , 1 - 10 ) of 3-week ( 60 - 75 mg/m2 ) docetaxel regimens and 5 mg prednisone twice per day . Seven (43.75%) patients completed more than six cycles. Ten (62.50%) patients had a good prostate-specific antigen (PSA) response of ≥50% decline. Eight (50.00%) patients had ostealgia before receiving docetaxel treatment and six of them (75.00%) experienced reduced pain after the treatment. Hematologic toxicity was observed in six (37.50%) patients with neutropenia, one of which was diagnosed with agranulocytosis and had to be admitted for the same reason. Other adverse reactions such as fever, debilitation, and alopecia were also observed. ### conclusions Very elderly patients (aged ≥80 years) with mCRPC are easy to be neglected and infrequently involved in clinical trials. Our study demonstrates that docetaxel chemotherapy plus prednisone is tolerable and effective among Chinese elderly patients (≥80 years) with mCRPC. docetaxel chemotherapy may be given under careful surveillance even in frail elderly patients.
