Resection Should be Considered for Residual Non-Retroperitoneal Disease in Post-Chemo NSGCTs

Jennifer M. King, MD, discusses results from a retrospective study on the prevalence of teratoma and active germ cell tumors in patients who have residual nonretroperitoneal disease following chemotherapy for nonseminomatous germ cell tumors, and what these findings indicate about the need for surgical resection in this patient population.

Although patients with metastatic nonseminomatous germ-cell tumors who had teratoma in the primary tumor were found to have a higher rate of teratoma in residual non-retroperitoneal disease following chemotherapy, those without teratoma in the primary tumor could have teratoma or active testicular germ-cell tumors in residual disease post-chemotherapy and should be considered for resection.

Jennifer M. King, MD, expands on the design and methodology of a retrospective study of teratoma in residual nonretroperitoneal disease post-chemotherapy and key findings regarding the correlation between teratoma in the primary tumor and rates of post-chemotherapy teratoma in residual non–nonretroperitoneal disease.

Dr King discusses the need for improved guidance when determining the appropriate management strategy for patients with residual nonretroperitoneal testicular cancer and findings from a study on the association between the presence of teratoma in the primary orchiectomy and the rate of teratoma in this disease.
