AB  - OBJECTIVE: To study the risk of endometrial cancer and breast cancer and the
      hysterectomy rate after endometrial ablation. METHODS: In this retrospective
      cohort study, records of all women with endometrial ablation at ages 30-49 years 
      in Finland (1997-2014) were extracted from the Hospital Discharge Register and
      linked to the Cancer Registry and Finnish Central Population Register. The
      primary outcome was cancer incidences in the endometrial ablation cohort compared
      with those in the background population of the same age. Secondarily, the
      postablation hysterectomy rate was compared with that of a control cohort of
      similar-aged women extracted from the Finnish Central Population Register.
      Multivariate regression models with adjustment for age, parity, number of
      cesarean deliveries, history of sterilization, and the duration of follow-up were
      evaluated as risk factors for postablation hysterectomy. RESULTS: In total, 154
      cancers (standardized incidence ratio [observed-to-expected ratio] 0.96, 95% CI
      0.82-1.13) were diagnosed among 5,484 women treated with endometrial ablation
      during the follow-up of 39,892 women-years. The standardized incidence ratio for 
      endometrial cancer was 0.56 (95% CI 0.12-1.64) and for breast cancer 0.86 (95% CI
      0.67-1.09). A total of 1,086 (19.8%) women had postablation hysterectomy. Risk of
      hysterectomy was almost fourfold in the endometrial ablation cohort compared with
      26,938 women in a control group (adjusted hazard ratio [HR] 3.63, 95% CI
      3.32-3.96). Factors predisposing to postablation hysterectomy were leiomyomas
      (adjusted HR 1.78, 95% CI 1.03-3.10), age younger than 35 years (adjusted HR
      1.44, 95% CI 1.15-1.81), at least two prior cesarean deliveries (adjusted HR
      1.27, 95% CI 1.04-1.55), and history of sterilization (adjusted HR 1.15, 95% CI
      1.01-1.32). CONCLUSION: Endometrial ablation was not associated with an elevated 
      endometrial cancer or breast cancer risk in Finland. Leiomyomas, young age, and
      history of prior cesarean deliveries or sterilization were associated with an
      increased risk of postablation hysterectomy.
