Objective: Through detection of 9 loci of polymorphisms of microsatellite to investigate the parental origin of complete hydatidiform mole.
Methods: Using the technology and method of multipolymerase chain reaction and electrophoresis in denatured polyacrylamide gel and silver stain detection, we carried out DNA analysis on 50 cases of complete hydatidiform mole diagnosed by histopathology and 50 copies of the couples' peripheral blood.
Results: There are 7 cases of biparental complete hydatidiform mole (14%); and 43 cases of androgenetic complete hydatidiform mole (86%) among 50 cases of complete hydatidiform mole.
Conclusions: Detection of polymorphisms of microsatellite is a technology that can be used to identify the parental origin of complete hydatidiform mole. It is simple, quick, reliable and highly efficient.

The distinction between choriocarcinoma and residual trophoblastic cell proliferation from a complete hydatidiform mole/invasive mole (CHM/IM) without villi is challenging on curettage materials. We investigated whether SALL4 immunostaining could help differentiate various gestational trophoblastic diseases. Placental site nodules (PSN; n=10), atypical PSN (APSN; n=8), placental site trophoblastic tumors (PSTT; n=9), epithelioid trophoblastic tumors (ETT; n=5), gestational choriocarcinomas (n=31), partial hydatidiform moles (PHM; n=13), CHM/IM (n=47), and nonmolar products of conception (POC) (n=26) were included.

BACKGROUND Gestational trophoblastic diseases (GTDs) are a group of benign and malignant tumors that arise from placental tissue. Ectopic pregnancies most commonly occur within the fallopian tubes. The estimated incidence of ectopic gestational trophoblastic diseases (GTDs) is approximated at 1.

Objective: To evaluate the efficacy of actinomycin D (ActD) as prophylactic chemotherapy (P-chem) in patients with high-risk complete hydatidiform mole (Hr-CHM) on progression to gestational trophoblastic neoplasia (GTN).
Methods: From 1996 to 2023, 426 Hr-CHMs were selected in a cohort of 1623 patients with gestational trophoblastic disease (GTD). From 1996 to 2023, 290 patients with Hr-CHMs received a single bolus dose of Act-D at the time of uterine evacuation (Hr-CHM P-chem group); 136 with the same risk factors did not receive P-chem (Hr-CHM control group).

Aim: While manual vacuum aspiration (MVA) is commonly employed for early first-trimester abortions, its effectiveness in treating hydatidiform mole is still unclear. This study sought to evaluate the efficacy and safety of MVA in comparison to dilation and curettage (D&C) for managing hydatidiform mole.
Methods: We conducted a retrospective review of medical records for 198 patients with hydatidiform mole treated at Nagoya University Hospital between 2004 and 2023.
