Sarcomas are rare but aggressive diseases. Specialized multidisciplinary management is not implemented for all patients in most countries. We investigated the impact of the surgery in a reference center on relapse and survival in the nationwide NETSARC/RREPS study.
NETSARC (netsarc.org) is a network of 26 reference sarcoma centers with specialized MDTB, funded by the French National Cancer Institute to improve the outcome of sarcoma patients. Since 2010, presentation to an MDTB and second pathological review are mandatory for sarcoma patients. Patients’ characteristics and follow-up are collected in a database regularly monitored. Uni and multivariate analysis of prognostic factors for local relapse free survival (LRFS), relapse free survival (RFS) and overall (OS) were conducted.
Out of the 9,594 non-metastatic pts aged > =15, with a first diagnosis of soft tissue and visceral sarcoma obtained between Jan 2010 and Dec 2014, 3505 (37%) and 6089 (63%) were operated within vs outside of one of the 26 NETSARC reference center. The former group had worse prognostic characteristics (age, size, grade, depth p
In this nationwide unselected population, the LRFS and RFS of sarcoma patients is worse than that reported in expert centers series. Surgery in reference center is associated with significant reduction of the risk of relapse and death.
Clinical trial identification
This is not a clinical trial this is a registry of sarcoma approved by the French NCI and competent authorities in France (CNIL)
