Improved prognosis of de novo metastatic prostate cancer after an introduction of life-prolonging agents for castration-resistant prostate cancer.
Background: In Japan, since 2014, new treatments such as androgen receptor signaling inhibitors and cabazitaxel have become applicable for metastatic castration-resistant prostate cancer (mCRPC), leading to dramatic changes in treatment options.
Objective: This study aims to evaluate the impact of recent advancements in treatment options on the overall survival (OS) of patients diagnosed with de novo metastatic castration-sensitive prostate cancer (mCSPC) in Japan.
Methods: A retrospective analysis was conducted on 2450 Japanese men diagnosed with de novo mCSPC between 2008 and 2018. Patients were stratified into two groups based on the period of diagnosis: an earlier period (2008-2013) and a later period (2014-2018). OS was compared between earlier and later periods using Kaplan-Meier analysis in total and propensity score matched subpopulation as well as risk-stratified subgroups.
Results: Patients diagnosed in the later period exhibited significantly improved OS compared to those diagnosed in the earlier period. The risk score, calculated based on ISUP grade group, LDH levels, and ALP levels, was a poor prognostic factor. In the later period, compared to the earlier period, there was no improvement in OS in the favorable-risk group, but a significant improvement was observed in the poor-risk group.
Conclusion: It was suggested that the introduction of novel androgen receptor signaling inhibitors and chemotherapy treatment regimens since 2014 has led to improved survival outcomes for patients with de novo mCSPC, particularly those with poor-risk profiles. The findings highlight the impact of recent advancements in treatment on the prognosis of patients with metastatic prostate cancer in Japan.
期刊介绍:
The International Journal of Clinical Oncology (IJCO) welcomes original research papers on all aspects of clinical oncology that report the results of novel and timely investigations. Reports on clinical trials are encouraged. Experimental studies will also be accepted if they have obvious relevance to clinical oncology. Membership in the Japan Society of Clinical Oncology is not a prerequisite for submission to the journal. Papers are received on the understanding that: their contents have not been published in whole or in part elsewhere; that they are subject to peer review by at least two referees and the Editors, and to editorial revision of the language and contents; and that the Editors are responsible for their acceptance, rejection, and order of publication.
