*Format for reporting to FIGO Annual Report: in order to stage and allot a risk factor score, a patient's diagnosis is allocated to a stage as represented by a roman numeral I, II, III, and IV. This is then separated by a colon from the sum of all the actual risk factor scores, which is expressed in Arabic numerals (e.g., stage II:4, stage IV:9). This stage and score will be allotted for each patient.
