Cervical ectopic pregnancies represent fewer than 0.1% of all ectopic pregnancies but carry increased risk of significant hemorrhage and long-term reproductive consequences if not managed properly. In part due to the rarity of their occurrence, a standard-of-care protocol for management of cervical ectopic pregnancy (EP) other than hysterectomy does not exist. A trend toward more conservative management has broadened the literature; however, it is unclear what clinical characteristics can be used to guide choice of treatment.This retrospective study aimed to investigate published cases of cervical EP to determine how initial patient characteristics may be used to guide management strategies based on treatment success rate. PubMed, EMBASE, and Web of Science were searched for peer-reviewed citations published between 2000 and 2018. Included cases reported one of the following: initial β-human chorionic gonadotropin (β-hCG), crown-rump length (CRL), or gestational sac diameter. Cases were excluded that reported heterotopic pregnancy, were a result of in vitro fertilization, or included cervicoisthmic pregnancy. Patient characteristics abstracted from studies included age, gravidity, parity, initial β-hCG, CRL, gestational sac diameter, presence of fetal cardiac activity, and hemodynamic stability at initial presentation. Also abstracted were outcomes including initial treatment success and failure defined as resolution of cervical EP with the predefined treatment plan and requirement of additional and unplanned interventions due to predefined treatment plan failure, respectively. The primary exposure variable was the treatment, which was divided into systemic methotrexate (MTX), uterine artery embolization (UAE), dilatation and curettage (D&C), potassium chloride, MTX + UAE, D&C + UAE, and other. The primary study outcome was the initial success of planned treatments provided to the patient.A total of 204 articles from 44 countries including 454 cases were reviewed. Median β-hCG was 14,733 mIU/mL and median gestational age 7 weeks 4 days. Compared with MTX alone, other treatment methods had an increased likelihood of initial treatment success including UAE (
