Abstract:
The clinical data of 1 patient with long-term survival metastatic prostate cancer were analyzed retrospectively, and the related literature was reviewed and discussed. The patient, male, 70 years old, was admitted to the hospital in 2009 due to dysuria with lower abdominal pain for one month.Blood PSA>1 000 ng/ml. The pathology of prostate biopsy was prostatic adenocarcinoma, Gleason score was 8 points (4+ 4), and was diagnosed as prostate cancer (T 4N 0M 1b) with bone metastasis. The patient underwent combined androgen-blocked treatment(castration and bicalutamide 50mg) for four years, then progressed to mCRPC. The initial treatment was continued in the fifth year due to the absence of novel therapeutic agents, and then symptoms progressed. The regimens were adjusted successively to increased anti-androgen (castration and bicalutamide 150 mg) from Jan 2015, then switch to another anti-androgen (Flutamide 250 mg) from Aug 2015, and then withdraw the anti-androgens from Feb 2016. All these treatments showed limited benefit for a relatively short time. The t-PSA increased steadily to over 1 000 ng/ml with persistent symptoms. In April 2017, he started the treatment with the original abiraterone acetate and underwent a PSA flare-up in the following month.tPSA decreased sharply since May 2017, less than 0.02ng/ml in Aug 2017. Meanwhile, the regimen relieved the ostealgia. He could take care of himself in daily life. raditional CAB therapy can maintain PSA-free progression and symptom-free progression for several years for some metastatic prostate cancer patients. After disease progression, the increased dosage of anti-androgens, the substitution of anti-androgen, and the withdrawal of anti-androgens showed limited benefit within a short time. However, the novel hormone therapy is still effective in relieving clinical symptoms and prolonging patients' survival time.
