Surgery is currently the only potentially curative treatment modality for localized retroperitoneal sarcoma (RPS). Available studies regarding oncologic outcomes are mainly retrospective in nature, and RPS are recognized as a rare disease. Therefore, prospective analysis of high quality data is a top priority.
Primary Objectives of this study are:
- to prospectively collect standardized clinical data and radiological and pathological material from primary RPS patients treated with surgery at reference centers.
- patient outcome will be evaluated in terms of overall survival (OS), disease-free survival (DFS), crude cumulative incidence (CCI) of local recurrence (LR) and distant metastasis (DM).
- to estimate the efficacy and safety of surgical treatment, including extended surgical approach to primary RPS;
- to prospectively evaluate the impact of multimodality therapy, including radiation therapy and chemotherapy;
- to identify clinical, radiological and pathological characteristics that may influence the oncological outcome or may be used as predictors of LR/DM/OS. These may be important biomarkers of disease;
- to utilize collected pathological material for research collaborations.

- Disease-free Survival [ Time Frame: 10 years ]Survival after surgery for primary RPS resection; any disease recurrence, local or distant, will be considered as an event at time of first radiological appearance.
- Overall Survival [ Time Frame: 10 years ]Overall Survival computed from date of surgery
- Crude cumulative incidence of Local recurrence [ Time Frame: 10 years ]CCI of Local recurrence computed from date of surgery, and defined as intrabdominal recurrent disease after complete resection
- Crude cumulative incidence of Distant metastasis [ Time Frame: 10 years ]CCI of distant metastasis computed from date of surgery, and defined as hepatic recurrence and / or extrabdominal recurrent disease
- Morbidity [ Time Frame: 60 days ]Postsurgical morbidity according to Clavien-Dindo classification
