[The excretion of chorionic gonadetropin in 55 cases of hydatidiform mole (author's transl)].

In 55 cases of hydatidiform mole, 323 quantitative assays of chorionic gonadotropin were evaluated. In cases of molar degeneration the mean HCG excretion was 20% below normal. In cases of hydatidiform mole and invasive mole the mean HCG excretion was significantly above normal. Many cases of hydatidiform mole and all cases of invasive mole showed a repeat rise of the HCG titres after curettage. The pattern of HCG excretion in hydatidiform mole is shown in diagrams.
