3484 - Updated analysis of the National Registry of Nervous System Tumors in Spain (RETSINE). RETSINE: National Registry of Nervous System Tumors of the Spanish Research Group in Neuro-oncology (GEINO) and Spanish Infrequent and Orphan Tumors Group (GETHI)

Background

The Spanish Research Group in Neuro-oncology (GEINO) and Spanish Infrequent and Orphan Tumors Group (GETHI) initiated a Nervous System Tumors Registry (RETSINE) in September 2017 with the aim of evaluating accurate, basic data concerning this oncological pathology in Spain. (Spanish Agency of Medicines and Medical Devices code: GG-TIN-2017-01).

Methods

The RETSINE database collects demographic, diagnostic and treatment data from all the hospitals participating in the project. Secondarily, each researcher indicates if there is a tumor sample available for future studies that arise from the registry.

Results

From September 2017 to April 2019, the registry has included 1021 patients (p) from 26 different hospitals. P have been included at a rate of 60 per month. With a median age of 60 y (range: 16-89), there is a discrete predominance in males (56.1%). The main symptoms at presentation are seizures, cognitive impairment and ataxia (26.1%, 16.8% and 6.6% of p). Histology provided in 841 p = 764/841 glioma (90,8%) [High Grade Glioma 618/764 (80.9%), Low Grade Glioma 146/764 (19.1%)], 77/308 no glioma (9,2%). Primary surgical treatment= 42.4% total tumor removal; 38.9% subtotal tumor removal and 7.7% biopsy. The median overall survival is 18.1 m (95% CI 15.5-20.6): 115.6 m (95% CI 38.8-192.4) in Low Grade and 17.5 m (95% CI 15.4-19.5) in High Grade Glioma.

Conclusions

RETSINE is a valuable tool for analyzing the current situation of Nervous System Tumors in Spain. The possibility of carrying out clinical studies in tumors of low incidence will be increased and improved with records of cases with associated biological sample. The database provides medical information that can also assist the orientation of healthcare policies.
