RISS scoring
Also written as: RISS — Revised International Staging System
Risk assessment system for testicular cancer combining clinical factors and tumor markers to predict treatment outcomes.
Full Definition
The Revised International Staging System (RISS) for testicular germ cell tumors is a prognostic classification system that incorporates histology, location of metastases, and serum tumor marker levels to stratify patients into good, intermediate, or poor risk categories. This system replaced the earlier International Germ Cell Cancer Collaborative Group (IGCCCG) criteria and provides more refined risk assessment for treatment planning. RISS scoring considers factors such as primary tumor site (gonadal vs. extragonadal), presence of pulmonary or non-pulmonary visceral metastases, and levels of alpha-fetoprotein (AFP), beta-human chorionic gonadotropin (β-hCG), and lactate dehydrogenase (LDH). The scoring system helps determine appropriate chemotherapy regimens and treatment intensity.
