Letrozole add-on in the Treatment of Cesarean Scar Pregnancy

Summary

It is hypothesized that the inhibition of estradiol production by letrozole may interfere with physiological effects of progesterone necessary to maintain the pregnancy. There is no reference treatment of cesarean scar pregnancy (CSP) as the limited number of cases precludes the extrapolation of results. In our center we successfully use two-step treatment with methotrexate (MTX) followed by hysteroscopic removal of products of conception (POC). The time in between is needed to achieve a decrease in the trophoblast's vital potential (B-hCG fall) and its vascularization. Additional administration of letrozole could further reduce the vital potential of the pregnancy, eliminating the need for another dose of MTX, resulting in faster healing and lower rate of complications.

Conditions

  • Cesarean Scar Pregnancy

Interventions

DRUG

MTX monotherapy

MTX in a single dose of 100 mg intravenously and 50 mg in intra-amniotic injection (day 0), along with 30 mg potassium chloride in case of positive fetal heartbeat (FH), and subsequent hysteroscopic evacuation of products of conception (POC)

DRUG

MTX + letrozole add-on

MTX in a single dose of 100 mg intravenously and 50 mg in intra-amniotic injection (day 0), along with 30 mg potassium chloride in case of positive fetal heartbeat (FH) + Letrozole in a daily dose of 5 mg (2 x 2.5 mg) orally for 10 days from day 0, and subsequent hysteroscopic evacuation of products of conception (POC)
