Collaborative Stage

Note: Clinician scoring is recommended. If any one of the factors is unknown, stop trying to assign score, unless you have already determined with the factors you have - low risk or high risk. The score on the Prognostic Scoring Index is used to substage patients. Substage A (low risk) and Substage B (high risk) are assigned on the basis of a non-anatomic risk factor scoring system: AGE [Score 0: age less than or equal to 40; Score 1: age 40 or more]; ANTECEDENT PREG [Score 0: Hydatidiform mole; Score 1: Abortion; Score 2: Term pregnancy]; MONTHS FROM INDEX PREG [Score 0: less than 4 months; Score 1: 4-6 months and less than 7 months; Score 2: 7-12 months to 12 months; Score 4: More than 12 months]; PRETREATMENT SERUM hCG(IU/ml) [Score 0: less than 10 to 3rd power, (1,000); Score 1: 10-3rd power to 10-4th power (1,000 to less than 10,000); Score 2: 10-4th power to less than 10-5th power (10,000 to less than 100,000); Score 4: greater than or equal to 10-5th power (100,000 or greater)]; LARGEST TUMOR SIZE, INCLUDING UTERUS [Score 0: less than 3 cm; Score 1: 3-less than 5 cm; Score 2: greater than or equal to 5 cm]; SITES OF METS [Score 0: Lung only or None; Score 1: Spleen, kidney; Score 2: Gastrointestinal tract; Score 4: Liver, brain]; NUMBER OF METS [Score 0: 0; Score 1: 1-4; Score 2: 5-8; Score 4: >8]; PREVIOUS FAILED CHEMOTHERAPY [Score 2: Single drug; Score 4: 2 or more drugs]. Sum the score of each prognostic risk factor(s) to determine the final Prognostic Scoring Index in the table below:

Code	Description

050	Stated to be substage A, but score not specified
110	Clinician stated high risk (sum score of 7 or greater or NOS)
150	Stated to be substage B, but score not specified
200	Clinician stated risk factors, but unknown whether low or high risk
