ESTICULAR CANCER IS THE MOST common cancer diagnosis in men between the ages of 15 and 35 years, with approximately 8000 cases detected in the United States annually. 1 The majority (95%) of testicular neoplasms are germ cell tumors (GCTs), with other testicular neoplasms (ie, sex-cord stromal tumors, lymphomas) occurring more rarely. Germ cell tumors may also arise in extragonadal locations, such as the mediastinum and retroperitoneum.Remarkable progress has been made in the medical treatment of advanced testicular cancer with a substantial increase in cure rates from approximately 25% in the mid-1970s to nearly 80% today. 2 This cure rate is the highest of any solid tumor and improved survival is primarily due to effective chemotherapy. 3 It is important for all physicians to be familiar with this malignancy, because patients may initially present to a variety of practitioners, and delays in therapy are associated with more extensive disease resulting in more intensive treatment and lower cure rates. 4 In addition, the immediate and longterm toxic effects of treatment often require management from physicians of various disciplines. This article reviews the current evidence-based treatments for advanced testicular GCT, and the acute and chronic toxic effects that may result. The management of early stage (I-IIA) testicular cancers has been reviewed elsewhere. [5][6][7]
BACKGROUND GCT Histology and GeneticsGerm cell tumors are malignancies of primordial germ cells, the cells destined to become spermatozoa. With neoplastic transformation, these cells take on a variety of histologies, reflect-See also Patient Page. CME available online at www.jamaarchivescme.com and questions on p 706.
