I agree with Dr. Kaunitz that the study has major limitations including as he states that it does break out of the types of uterine cancer. I would add a second limitation that it lacks information concerning the pre-op screening procedures. However, it has some very useful data regarding age. In addition, although it does not break out the types of uterine cancers, Dr. Wright who authored the study stated that between 10 and 20% of uterine cancers are uterine sarcomas (Outpatient Surgery (Aug edition). Other experts have estimated a lower rate, but assuming a rate of 15%, the study indicates that for women younger than 40, approximately 1 in 11,000 will have an undetected sarcoma compared to women over 65 who would have a rate of 1 in 219. And of course the rate would be even less if you agree with other experts that sarcomas make up significantly less than 15% of all uterine cancers.
In an FDA hearing concerning the use of power morcellators, Dr. Jubilee Brown presented a study that found that even if you assume an undetected sarcoma rate as high as approximately 1 in 500 women, a MIS procedure using a power morcellator will save lives compared to full open abdominal surgery. If you combine the results of the 2 studies, for women under 40, a MIS procedure would be far safer so if any procedure should be banned (and I am not advocating banning procedures), it is the full open abdominal surgeries. For added reference, the study predicts rates of undetected sarcomas for women between 50-54 at 1-1958 and 55-59 at 1 in 492. So at least through the 50-54 age group, the MIS procedure according to Brown’s study would be safer. Of course, hopefully doctors and scientists will continue to develop better procedures to identify cancers preoperatively.
