Among 4,325 cases with complete information for the five risk factors, cumulative recurrence risk to PAN was examined based on the patterns of risk factors. Patterns with risk of PAN recurrence ≥8% are emboldened.

LVSI, lympho-vascular space invasion; PAN, para-aortic lymph node; PLN, pelvic lymph node.
