Abstract

AIM

To determine the incidence and prognosis of non-endometrioid endometrial cancer (EC) in relation to the use of metformin, other antidiabetic medication (ADM) and statins in patients with type 2 diabetes (T2D).

MATERIALS AND METHODS

In order to analyze the incidence and prognosis of non-endometrioid EC, two cohorts were obtained from a nationwide diabetes database (FinDM); 57 non-endometrioid ECs were observed in a cohort of 92,366 women with newly-diagnosed T2D during the follow-up (1996 to 2011) to assess the incidence, and a retrospective cohort of 105 women with T2D diagnosed with non-endometrioid EC (1998 to 2011) was used to estimate cumulative mortality from EC and other causes of death. Hazard ratios (HRs) with 95% confidence intervals (CIs) for EC incidence were estimated in the full-cohort analysis and in the nested case-control analysis, matched for age and duration of T2D. Cumulative mortality was estimated by using the Aalen-Johansen estimator. Cause-specific mortality rates were analyzed by using Cox models regarding the pre-diagnostic use of different forms of ADM and statins.

RESULTS

In the nested case-control analysis, the use of metformin was not associated with the risk of non-endometrioid EC (HR=1.09, 95% CI=0.59-2.00), whereas statin use was associated with a lower risk (HR=0.47, 95% CI=0.26-0.84). The results from the full-cohort analysis supported these findings. Mortality from non-endometrioid EC was not different between users of metformin and other types of oral ADM (HR=1.56, 95% CI=0.40-6.07) but was observed to be lower in statin users (HR=0.41, 95% CI=0.20-0.82).

CONCLUSION

Our findings were inconclusive regarding the association of metformin with the risk and prognosis of non-endometrioid EC. However, statin use was associated with a lower incidence and mortality from this disease.

摘要

目的

确定2型糖尿病（T2D）患者中，使用二甲双胍、其他抗糖尿病药物（ADM）和他汀类药物与非子宫内膜样子宫内膜癌（EC）的发病率及预后之间的关系。

材料与方法

为分析非子宫内膜样EC的发病率及预后，从全国糖尿病数据库（FinDM）中获取了两个队列；在随访期间（1996年至2011年），对92366例新诊断为T2D的女性队列进行观察，其中有57例非子宫内膜样EC，以评估发病率，同时使用一个回顾性队列，该队列包含105例诊断为非子宫内膜样EC的T2D女性（1998年至2011年），用于估计EC及其他死因的累积死亡率。在全队列分析和巢式病例对照分析中，对EC发病率的风险比（HR）及95%置信区间（CI）进行估计，并根据年龄和T2D病程进行匹配。使用Aalen-Johansen估计器估计累积死亡率。通过Cox模型分析不同形式的ADM和他汀类药物诊断前使用情况的特定病因死亡率。

结果

在巢式病例对照分析中，使用二甲双胍与非子宫内膜样EC风险无关（HR = 1.09，95% CI = 0.59 - 2.00），而使用他汀类药物与较低风险相关（HR = 0.47，95% CI = 0.26 - 0.84）。全队列分析结果支持这些发现。二甲双胍使用者与其他类型口服ADM使用者的非子宫内膜样EC死亡率无差异（HR = 1.56，95% CI = 0.40 - 6.07），但他汀类药物使用者的死亡率较低（HR = 0.41，95% CI = 0.20 - 0.82）。
