Urologists often are faced with challenges in treating men with metastatic prostate cancer. Although historically chemotherapy has had limited utility in treating this disease, therapeutic nihilism surrounding its use is no longer warranted, as demonstrated by results of 2 recent randomized clinical trials showing that docetaxel-based chemotherapy improves survival in patients with hormone-refractory prostate cancer (HRPC). Although the survival benefit was a modest 2 months, the results hold the promise that docetaxel-based treatment in earlier-stage disease may provide a longer survival advantage. The Cancer and Leukemia Group B (CALGB) 90203 and TAX 3501 studies are phase 3 neoadjuvant and adjuvant radical prostatectomy trials designed to assess the role of docetaxel in patients with high-risk localized disease. These 2 trials, along with the Southwest Oncology Group (SWOG) 9921 trial, which will assess the potential for adjuvant mitoxantrone, are paving the way for earlier systemic treatment. The need for better therapies for patients routinely seen in the urology clinic and the potential for improvements with chemotherapy necessitate an increasing collaboration between urologists and oncologists. Referral to a medical oncologist for a full discussion of treatment options is in the best interest of patients with HRPC, and patients at high-risk for treatment failure should be encouraged to consider clinical trial enrollment.
泌尿外科医生在治疗转移性前列腺癌男性患者时常常面临挑战。尽管从历史上看,化疗在治疗这种疾病方面的效用有限,但围绕其使用的治疗虚无主义已不再合理,最近两项随机临床试验的结果表明,以多西他赛为基础的化疗可提高激素难治性前列腺癌(HRPC)患者的生存率。尽管生存获益仅为适度的2个月,但这些结果预示着在疾病早期阶段采用以多西他赛为基础的治疗可能会带来更长的生存优势。癌症与白血病B组(CALGB)90203和TAX 3501研究是旨在评估多西他赛在高危局限性疾病患者中作用的3期新辅助和辅助根治性前列腺切除术试验。这两项试验,连同将评估辅助米托蒽醌潜力的西南肿瘤协作组(SWOG)9921试验,正在为早期全身治疗铺平道路。对于泌尿外科诊所中常规诊治的患者,需要更好的治疗方法,且化疗有改善病情的潜力,这就使得泌尿外科医生和肿瘤内科医生之间的合作日益必要。将患者转诊给肿瘤内科医生以全面讨论治疗方案,这符合HRPC患者的最大利益,对于有治疗失败高风险的患者,应鼓励其考虑参加临床试验。
