Blood flow in the site of invasive moles within the myometrium after completion of chemotherapy: retrospective study of 33 patients

摘要

Objectives: Women with invasive moles (IMs) should continue with one or two cycles of chemotherapy until the level of human chorionic gonadotrophin (hCG) concentrations become normal. However, assessment of blood flow (BF) with Doppler ultrasonography (DU) in the myometrial mass after chemotherapic completion has not been reported. Materials and Methods: We intended to find out the outcomes of BF associated with different treatments during following-up by DU. The patients were employed different treatments (resection, chemotherapy or following-up). We use the Kaplan-Meier method to perform survival analysis between different groups. Results: Of 33 cases, two patients underwent resection of the mass, five patients had 1-2 additional cycles of chemotherapy, and the other 26 subjects had follow-up without additional treatment. There were no significant differences in initial hCG values, chemotherapy cycles, risk scores for IM, and diameter of masses between the two groups. However, differences in BF disappearance time in the two groups were detected, and hCG levels did not increase again in the two groups. Conclusions: These data suggest that IM patients can be followed up if DU reveals BF within masses in the uterine myometrium after completion of chemotherapy.
