Retroperitoneal sarcoma (RPS) is a rare malignancy arising from mesenchymal cells that most commonly presents as an abdominal mass and is associated with poor prognosis. Although several studies have assessed the survival benefits of wide excision, few have reported detailed methods for achieving wide excision in patients with RPS.
To describe our experience with multidisciplinary surgical resection of RPS using intra- and extra-pelvic approaches.
Multidisciplinary surgery is an anatomical approach that combines intra- and extra-peritoneal access within the same surgery to achieve complete RPS removal. This retrospective review of the records of patients who underwent multidisciplinary surgery for RPS analyzed surgical and survival outcomes.
Eight patients underwent 10 intra- and extra-pelvic surgical resections, and their median mass size was 12.75 cm (range, 6-45.5 cm). Using an intrapelvic approach, laparoscopy-assisted surgery was performed in four cases and laparotomy surgery in six. Using an extrapelvic approach, ilioinguinal and posterior ap
RPS is therapeutically challenging because of its location and high risk of recurrence. Therefore, intra- and extra-pelvic surgical approaches can improve the macroscopic security of the surgical margin.
Core Tip: Retroperitoneal sarcomas (RPS) are therapeutically challenging because of their location and high risk of recurrence. Multidisciplinary surgery is an anatomical approach that combines intra- and extra-peritoneal access within the same surgery to achieve complete RPS removal. This retrospective review of the records of eight patients who underwent multidisciplinary surgery for RPS analyzed surgical and survival outcomes. All patients’ RPS masses were removed completely, and four achieved R0 resection through intra- and extra-pelvic surgery. Therefore, intra- and extra-pelvic surgical approaches can improve the macroscopic security of the surgical margin.
