Nason GJ, Donahoe L, de Perrot M, et al. - This study was carried out to correlate a simultaneous vs sequential approach to residual post chemotherapy mass resections in metastatic testis cancer. Researchers conducted a retrospective review of individuals who underwent retroperitoneal and thoracic/cervical resection of post-chemotherapy residual masses between 2002 and 2018. Group 1: “Simultaneous” (Combined Retroperitoneal and Thoracic/Cervical resections on the same date); Group 2: “Sequential” (Retroperitoneal and Thoracic/Cervical resections at separate dates). They conducted 35 simultaneous and 17 sequential resections during the study period. In some individuals, simultaneous resection of retroperitoneal and thoracic/cervical post-chemotherapy metastases was found to be feasible. It needs multidisciplinary collaboration and a longer primary procedure.
