From: Role of primary surgery in advanced ovarian cancer

Residual tumor status* Maximum diameter of residual tumor Maximum total volume of residual tumor
Optimal Microscopic No visible tumor
Minimal < 1 cm ≤ 10 cm3
Intermediate 1 – 2 cm > 10 cm3 but ≤ 100 cm3
Gross > 2 cm > 100 cm3
  1. *To assign residual tumor to a certain status, both criteria, diameter and volume, have to be fulfilled. Otherwise the next lower category should be used.
