An important point relates to which patients are suitable candidates for PADT. Methods: A retrospective review of the efficacy of PADT in 628 patients with localized or locally advanced PCa treated with PADT at seven institutions in Japan was carried out. Results: It was found that more than 30% of low- or intermediate-risk localized PCa patients could have their disease controlled over the long-term by PADT alone. Short-term or intermittent PADT could not be recommended because of the possibility of character change in the cancer cells as a result of incomplete androgen ablation. Conclusion: Algorithms are proposed for the treatment of localized PCa not only in low- and intermediate-risk groups, but also in the high-risk group. Future research directions are indicated. © 2008 WPMH GmbH., 金沢大学医薬保健研究域医学系}, pages = {333--341}, title = {Androgen and prostate cancer: the role of primary androgen deprivation therapy in localized prostate cancer}, volume = {5}, year = {2008} }
