A controlled trial of bestatin in hydatidiform mole.
A prospective randomized controlled trial was conducted to study whether Bestatin, an immunomodifier, can reduce the incidence of persistent gestational trophoblastic disease in patients with hydatidiform mole. A group of 21 patients (Bestatin group) received 30 mg Bestatin daily after evacuation of the hydatidiform mole. A second group of 23 patients (control group) did not receive any drug. Blood was taken for white cell counts, differential counts, lymphocyte subset counts (CD2+, CD4+, CD8+ and B cells) and natural killer cell activity before evacuation of the hydatidiform moles. The tests were repeated every 4 weeks after evacuation until the serum beta subunit of human chorionic gonadotropin (beta hCG) had returned to normal or until the patient had to receive chemotherapy because of persistent gestational trophoblastic disease. There was no significant difference in the age of the patients, the pre-evacuation serum beta hCG, or the gestational age between the two groups. Chemotherapy was needed by 6 patients in the Bestatin group (28.6%) and 3 patients in the control group (13%) because of persistent gestational trophoblastic disease. There was no significant difference in any of the immunological parameters between the two groups before or after evacuation. We conclude that Bestatin at this dosage does not improve the immunological functions or clinical outcome in patients with hydatidiform mole.
