Methods: This retrospective study had been performed in Yildirim Beyazit University between January 2010 and December 2015. Demographic and clinical characteristics, ultrasonografic findings, pretreatment serum β-human chorionic gonadotropin (β-hCG) and progesterone levels of 58 patients with EP were retrieved from hospital records retrospectively. The patients were grouped according to MTX treatment success (response vs. failure). Results: Single-dose MTX-treatment was successful in 72.4% (42/58) of patients. The mean pretreatment β-hCG level was significantly lower in responders than in failures (2080 ± 2322 vs. 5707 ± 3885 IU/L, p = 0.001), and 2678 IU/L was the most suitable cutoff to predict success (75% sensitivity, 73.8% specificity). Moreover, failure rate was 8.45 times more in group of patients whose β-hCG values were determined above the cutoff. The presence of fetal cardiac activity adversely affected treatment success (odds ratio = 12, p = 0.004). Treatment success was not affected by past history of ectopic pregnancy, thickness of endometrium, progesterone value or presences of pseudosac and free pelvic fluid. Conclusion: The success rate of single dose MTX in this study was 72.8%, and we found that failure rate of MTX treatment was 8.45 times more in group of patients whose initial serum β‑hCG values were above 2678 IU/L and 12 times more in patients with fetal cardiac activity.
