Management of clinical stage I non seminomatous germ cell tumor includes surveillance, primary chemotherapy and retroperitoneal lymph node dissection. Stratifying clinical stage I disease to high-and low-risk groups for harboring micrometastic retroperitoneal disease (pathologic stage B) is based on pathologic characteristics of the primary tumor. The presence of embryonal dominant histology and lymphovascular invasion (high-risk group) predicts for a 50% incidence of retroperitoneal disease. Low-risk group, the absence of either factor, predicts a 20% chance of retroperitoneal disease. Irrespective of risk classification, all treatment modalities have equal survival rates of 99% to 100%, and differ only in their unique short and long-term modalities. The mode of treatment in clinical stage I disease should remain patient driven and is guided by the perceived morbidities of each therapy.
临床I期非精原细胞瘤性生殖细胞肿瘤的管理包括监测、一线化疗和腹膜后淋巴结清扫术。根据原发肿瘤的病理特征,将临床I期疾病分为有微小转移腹膜后疾病(病理分期B)的高危和低危组。胚胎型为主的组织学类型和淋巴管浸润(高危组)提示腹膜后疾病发生率为50%。低危组,即不存在上述任何一个因素,提示腹膜后疾病发生率为20%。无论风险分类如何,所有治疗方式的生存率均为99%至100%,仅在其独特的短期和长期模式上有所不同。临床I期疾病的治疗模式应仍由患者主导,并以每种治疗方法所感知的发病率为指导。
