FIGO modified Prognostic Scoring System. The system evaluates the patients to those with GTN as low-risk and high-risk based on several risk factors such as age, pregnancy or interval of pregnancies, size or metastases of tumor and prior chemotherapy. Each risk factors are rated at levels 0-4 scores. The numbers are then added up, and the overall score determines a woman's risk level. * Women with a score of 6 or less are at low risk and tend to have a good prognosis regardless of how far the cancer has spread which usually respond well to chemotherapy. * Women with a score of 7 or more are at high risk, and their tumors tend to respond less well to chemotherapy, even if they haven't spread much. They may require more intensive chemotherapy. Therefore, some studies have shown that the condition is harder to cure if the cancer has spread to the liver or brain or β-hCG level is higher than 40,000 mIU/mL when treatment begins, cancer returns after having chemotherapy or symptoms/ pregnancy occurred for more than 4 months before treatment.
