CINSARC and Sarculator in Patients with Primary Retroperitoneal Sarcoma: A Combined Analysis of Single-Institution Data and the EORTC-STBSG-62092 Trial (STRASS).

ABSTRACT:

Purpose

The Complexity INdex in SARComas (CINSARC) predicts the metastatic risk in patients with soft-tissue sarcoma. The aims of this study were to provide the first independent validation of CINSARC in patients with retroperitoneal sarcoma (RPS) and evaluate whether CINSARC could enhance the performance of Sarculator.

Experimental design

A retrospective cohort included patients with primary localized RPS resected with curative intent (2011-2015) at a single institution. The STRASS cohort comprised patients from the surgery-only arm of the EORTC-STBSG-62092 (STRASS) trial who had undergone CINSARC categorization. Patients were classified as CINSARC low-risk (C1) versus high-risk (C2). Primary study endpoints were overall survival (OS) and disease-free survival (DFS). Sarcul
