Because of the small number of relapsed patients, their prognostic variability and the complexity of second-line therapy, randomized studies are largely lacking and treatment recommendations for patients with relapse after first-line chemotherapy are derived from retrospective series or phase II studies. This review summarizes the existing evidence including several recently published larger studies on the use of high-dose chemotherapy in these patients.
Patients with unfavorable features such as incomplete response to first-line therapy, cisplatin refractoriness, multiple relapses or advanced stage at initial diagnosis have been shown to benefit from salvage high-dose chemotherapy with autologous stem cell support. Long-term survival rates of up to 60% have been reported after salvage high-dose chemotherapy for these patients. The treatment for patients relapsing after complete remission to first-line therapy, cisplatin-sensitive disease and gonadal primary remains controversial. Excellent long-term event-free survival rates of up to 80% have been reported after both conventional and high-dose chemotherapy. Surgery remains an important part of any salvage strategy.
The prognosis of patients relapsing after first-line cisplatin-based chemotherapy has improved with multimodality therapy including conventional and high-dose chemotherapy, surgery and radiation. The treatment of these patients requires a close cooperation of experienced medical oncologists, urologists and radiation oncologists.
由于复发患者数量较少、预后存在变异性以及二线治疗的复杂性,随机研究基本缺失,一线化疗后复发患者的治疗建议来自回顾性系列研究或II期研究。本综述总结了现有证据,包括最近发表的几项关于在这些患者中使用高剂量化疗的较大规模研究。
具有不良特征的患者,如对一线治疗反应不完全、顺铂难治、多次复发或初诊时处于晚期,已被证明可从自体干细胞支持下的挽救性高剂量化疗中获益。这些患者接受挽救性高剂量化疗后的长期生存率据报道高达60%。对于一线治疗完全缓解后复发、顺铂敏感疾病和性腺原发性疾病的患者,治疗仍存在争议。传统化疗和高剂量化疗后均有高达80%的出色长期无事件生存率的报道。手术仍然是任何挽救策略的重要组成部分。
一线基于顺铂化疗后复发患者的预后通过包括传统化疗和高剂量化疗、手术及放疗的多模式治疗得到了改善。这些患者的治疗需要经验丰富的医学肿瘤学家、泌尿科医生和放疗肿瘤学家密切合作。
