A seemingly surprising increase in incidence of Endometrial Cancer

The ACOG 2017 saw several interesting results come out. One surprising result, presented at an oral presentation, appears to be a presentation about the increase in the incidence of Endometrial Cancer.

It appears that Endometrial Cancer rates were stable from 1999 to 2002, but then, since 2006 to 2014, the rates appear to have increased by 10%.

The authors were curious, as you and I might be, so they examined EC incidence through the Surveillance, Epidemiology, and End Result Program database from 1975 through 2014.

Factors affecting Endometrial Cancer

It appears that FDA approved hormonal therapies have dropped in number, and therefore the use of non FDA approved combinations of estrogen and estrogen+progesterone, which may not be enough to stop endometrial cancer.

Obesity, which has been increasing consistently, already a known risk factor, might be aggravated.

Study Limitations

The study, as stated by the authors themselves, is clearly not a randomized clinical trial, but an ecological study. Therefore, it is not sufficient to draw conclusions and yet, the findings, especially the coincidence of the use of non-approved hormonal therapy and the increase in endometrial cancer as well as factors such as obesity is quite interesting, and this should be flushed out further, perhaps with targeted studies. Women, in particular should be aware of risk factors and seek medical help in advance.
