- Abstract
<bold>Introduction: </bold>We aimed to assess the prognostic significance of early βhCG change and baseline progesterone level on treatment outcome among women receiving single dose Methotrexate protocol for tubal ectopic pregnancy (EP).<bold>Material and Methods: </bold>Retrospective study involving all consecutive patients diagnosed with EP and receiving Methotrexate therapy form January 2015 to December 2016. Patients were stratified into 2 groups according to treatment outcome: success group (n = 66) involved women who displayed complete resolution of serum βhCG levels following a single course of Methotrexate; failure group (n = 55) included patients who required repeated Methotrexate administration and/or surgical management. Predictive performances of baseline progesterone and ratio"βhCG level on day 4/ βhCG level on day 1″ (d4/d1) on treatment outcome were assessed using Receiving Operating Characteristics curves.<bold>Results: </bold>The ratio d4/d1 displayed good performances in predicting treatment outcome (AUC = 0.826). A ratio ≤ 0.7 was associated with a success rate of 94% after 1 course of Methotrexate and 100% after 2 courses. In contrast, a ratio >1.7 was associated with a failure rate of 100%. Conversely, baseline progesterone showed poor performances (AUC = 0.611).<bold>Conclusions: </bold>Patients with extreme βhCG changes (n = 33) on day 4 might benefit from a more personalized approach: simplified monitoring in those with a decline ≥30%, anticipated second course of treatment in those with an increase > 70%.
