RESUMO
RESEARCH QUESTION: What is the cost-effectiveness of gonadotrophins compared with clomiphene citrate in couples with unexplained subfertility undergoing intrauterine insemination (IUI) with ovarian stimulation under strict cancellation criteria? DESIGN: A cost-effectiveness analysis alongside a randomized controlled trial (RCT). Between July 2013 and March 2016, 738 couples were randomized to gonadotrophins (369) or clomiphene citrate (369) in a multicentre RCT in the Netherlands. The direct medical costs of both strategies were compared. Direct medical costs included costs of medication, cycle monitoring, insemination and, if applicable, pregnancy monitoring. Non-parametric bootstrap resampling was used to investigate the effect of uncertainty in estimates. The cost-effectiveness analysis was performed according to intention-to-treat. The incremental cost-effectiveness ratio (ICER) between gonadotrophins and clomiphene citrate for ongoing pregnancy and live birth was assessed. RESULTS: The mean costs per couple were 1534 for gonadotrophins and 1067 for clomiphene citrate (mean difference of 468; 95% confidence interval [CI] 464-472). As ongoing pregnancy rates were 31% in women allocated to gonadotrophins and 26% in women allocated to clomiphene citrate (relative risk 1.16, 95% CI 0.93-1.47), the ICER was 21,804 (95% CI 11,628-31,980) per additional ongoing pregnancy with gonadotrophins and 17,044 (95% CI 8998-25,090) per additional live birth with gonadotrophins. CONCLUSIONS: Gonadotrophins are more expensive compared with clomiphene citrate in couples with unexplained subfertility undergoing IUI with adherence to strict cancellation criteria, without being significantly more effective.

Endometrial carcinoma (EC) is the most common extracolonic tumor associated with hereditary nonpolyposis colorectal cancer (HNPCC). HNPCC increases the risk of EC compared to the general population. Patients with HNPCC have a better prognosis than patients with common sporadic colorectal cancer. It is unknown, however, whether the survival rate of HNPCC-associated EC is higher than that of sporadic EC. The aim of our study was to compare the survival rates of HNPCC-associated EC with sporadic EC. From the registry of the Netherlands Foundation for Hereditary Tumors, 50 patients with HNPCC-associated EC from 46 families harboring a germline mutation or fulfilling the Amsterdam Criteria II were age- and stage-matched with 100 patients with sporadic EC registered in the Eindhoven Cancer Registry in the Netherlands. Survival rates were analyzed. The overall 5-year cumulative survival rates for patients with HNPCC-associated EC was 88% and 82% for patients with sporadic EC (p = 0.59). In Stages IA, IB and IC, the survival rates of patients with HNPCC-associated EC and sporadic EC were 92% and 91%, respectively (p = 0.90). In Stages IIIA and IIIC, the survival rates for HNPCC-associated EC and sporadic EC were 72% and 50%, respectively (p = 0.38). Furthermore, there was no significant difference in the distribution of tumor histologic subtypes in the study and control groups (p = 0.55). The outcomes in survival in EC in the general population and in women from families with HNPCC do not differ significantly. These results may have important implications in our understanding of EC and the role of early screening.
