OBJECTIVE: Several European and American guidelines recommend to perform an additional hysterectomy in patients with cervical adenocarcinoma in situ (AIS), who initially received conservative treatment and who completed childbearing during follow-up. This study aimed to evaluate cost-effectiveness of performing an additional hysterectomy in comparison to expectative management.
METHODS: This post-hoc analysis was based on a retrospective cohort of patients diagnosed with AIS, who were conservatively treated by a radical (i.e., negative surgical margins) large loop excision of the transformation zone (LLETZ) or cold-knife conisation (CKC) in the Netherlands between 1990 and 2021. Based on these data, we estimated and compared the harms, benefits, and costs in 1000 simulated patients, both with and without an additional hysterectomy five years after conservative treatment for AIS. In the sensitivity analyses, we varied the timing of the additional hysterectomy, the risk of recurrent high-grade cervical dysplasia and cervical cancer risk after AIS treatment, and the utility loss for hysterectomy.
RESULTS: Less than 2 % of the patients who did not receive an additional hysterectomy after AIS developed cervical cancer. When an additional hysterectomy was performed, no quality adjusted life-years (QALYs) were gained and costs were 863 % higher (€6203,485 versus €644,238). Only when assuming no utility loss for a hysterectomy, QALYs were gained resulting in a cost-effectiveness ratio of €144,273, which is far above the cost-effectiveness threshold of €20,000.
CONCLUSION: It is not cost-effective to perform an additional hysterectomy after completion of childbearing in patients who were primarily treated by a radical LLETZ or CKC.
