Combined analysis of clinical features, human chorionic gonadotropin (hCG) value, and hCG ratios for early prediction of postmolar gestational trophoblastic neoplasia
Purpose: To investigate factors predicting postmolar gestational trophoblastic neoplasia (GTN) by combined analysis of clinical features, human chorionic gonadotropin (hCG) value, and hCG ratios. Methods: This retrospective study enrolled patients with histopathologically proven molar pregnancy. Pat...

Mahidol University Medicine Purpose: To investigate factors predicting postmolar gestational trophoblastic neoplasia (GTN) by combined analysis of clinical features, human chorionic gonadotropin (hCG) value, and hCG ratios.
