Implementation of a new histological grading system in ovarian mucinous carcinomas and its association with the risk of recurrence: a retrospective cohort study

Key Points

• GBG 2 tumors show a notably higher risk of recurrence compared to GBG 1 tumors, underscoring the grading system's importance.
• Only the GBG grading system predicted recurrence risk effectively, while FIGO grading did not demonstrate such a correlation.
• The study's retrospective cohort analyzed histological grading systems, highlighting their potential prognostic implications.
• Findings suggest that further studies are needed to establish the clinical relevance of the GBG grading system.
