Retroperitoneal sarcoma (RPS) is a rare malignancy 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.
Considering poor prognosis of RPS, we'd like to find effective surgical approach to complete resection for RPS. This Multidisciplinary surgery is an anatomical approach that combines intra- and extra-peritoneal access within the same surgery to achieve complete RPS removal.
We described our experience with multidisciplinary surgical resection of RPS using intra- and extra-pelvic approaches.
This study reviewed of the records of patients who underwent multidisciplinary surgery for RPS analyzed surgical and survival outcomes retrospectively.
All patients’ RPS masses were removed completely, and four achieved R0 resection through intra- and extra-pelvic surgery.
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.
These findings support the need for a multicenter or randomized controlled study to test the effectiveness of the multidisciplinary approach, despite the Trans-Atlantic RPS Working Group’s current guideline that the multidisciplinary approach is superior for complete tumor resection.
