Objective: To describe outcomes of expectant management (EM) versus methotrexate (MTX) treatment in tubal pregnancies with pretreatment human chorionic gonadotropin (hCG) less than 2000 mIU/mL. Methods: This retrospective cohort from two tertiary hospitals included women with confirmed tubal pregnancies and pretreatment hCG <2000 mIU/mL. Exclusion criteria were unrecorded pregnancy site, unconfirmed diagnosis, and surgical treatment upon diagnosis. The primary outcome was eventual rate of surgical treatment. Results: Between December 2009 and June 2021, 545 of 2114 (25.8%) women diagnosed with a tubal pregnancy met our inclusion criteria. We compared women who underwent EM (N = 201) with women who received MTX (N = 344). All women in the EM group had a declining trend of hCG. The MTX group had higher pretreatment hCG and higher rates of yolk sac or embryo presence on ultrasound. Eventual surgical treatment rate was higher in the MTX group compared with the EM group (39 [11.3%] vs. 9 [4.5%], P = 0.006), with no difference in the treatment failure rate or tubal rupture rate. In a subgroup analysis of women with pretreatment hCG between 1000 and 2000 mIU/mL, eventual surgical treatment, treatment failure, and tubal rupture rates did not differ between groups. Logistic regression analysis revealed that eventual surgical treatment was independently associated with hCG levels less than 1000 mIU/mL (adjusted odds ratio [aOR] 0.28, 95% confidence interval [CI] 0.14–0.56) and endometriosis (aOR 9.20, 95% CI 3.55–23.81). Conclusion: Expectant management of tubal pregnancies with pretreatment hCG levels less than 2000 mIU/mL and even between 1000 and 2000 mIU/mL and with a declining trend of hCG demonstrated lower or comparable rates of eventual surgical treatment, when compared with MTX treatment. Synopsis: Tubal pregnancies with pretreatment hCG ≤2000 mIU/mL and managed expectantly resulted in non‐inferiority lower or comparable rates of eventual surgical treatment compared with methotrexate treatment.

Early onset colorectal cancer (EO-CRC) is increasing. We investigated the risk factors for ER-CRC compared to late onset CRC (LO-CRC). CRC patients between the years 1999 and 2021 were retrospectively evaluated. Data regarding demographics, comorbidities, malignancies, and mortality were collected. Data were retrieved using the MdClone platform from a large Health Maintenance Organization. The cohort was subdivided into EO-CRC (age ≤50 years) and LO-CRC (age ≥51 years) groups. 61,679 patients diagnosed with CRC were included in our analysis, 30,456 (49.4%) males, and 4,891 (7.9%) Arabs, with an average age at diagnosis of 70.1±13.1 years. 5561 (9%) patients were included in the EO-CRC group. Over the last decades, higher rates of EO-CRC were diagnosed compared to the previous decade, 9.8% vs 8.3%, p<0.001. A higher percentage of EO-CRC patients were females (52.8% vs 50.4%), had a family history of CRC (9.9% vs 5.5%), were Arabs (18.7% vs 6.9%), and were smokers (32.7% vs 30.2%) compared to LO-CRC patients. Significantly lower rates of comorbidities such as ischemic heart disease, diabetes mellitus, hypertension, obesity, and iron deficiency anemia were found among EO-CRC patients, with a lower all-cause mortality (27.7% vs 63.1%, p<0.001). 348 (6.3%) of the EO-CRC patients had another Lynch-related cancer until age 50 years compared to 45 (0.1%) at the LO-CRC. Young individuals with increased risk for CRC need special consideration and should be referred early for screening and endoscopic investigation, particularly those with a family history of CRC, smokers, and those of Arab ethnicity.
