ARTICLE HIGHLIGHTS
Research background

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.

Research motivation

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.

Research objectives

We described our experience with multidisciplinary surgical resection of RPS using intra- and extra-pelvic approaches.

Research methods

This study reviewed of the records of patients who underwent multidisciplinary surgery for RPS analyzed surgical and survival outcomes retrospectively.

Research results

All patients’ RPS masses were removed completely, and four achieved R0 resection through intra- and extra-pelvic surgery.

Research conclusions

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.

Research perspectives

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.
