Strong Support

For women having open abdominal surgery to treat endometrial cancer, the thickness of the psoas major muscle does not reliably predict whether they will experience complications after surgery.

Predictive efficacy of rectus abdominis muscle and psoas major muscle thickness for postoperative morbidity in patients with endometrial cancer

Case-Control Study
Human
2025 Jun 10

This study found that the size of the psoas muscle in women having surgery for uterine cancer doesn't help predict if they'll have complications afterward — so it's not a useful tool for doctors to use for that purpose.

Similar Assertions

In women having open abdominal surgery for endometrial cancer, having thinner abdominal muscles (below 7.52 mm) is linked to a 44.8% chance of experiencing complications after surgery, but this link is not strong enough to be considered a standalone predictor once age and surgery length are taken into account.

For women having open abdominal surgery to treat endometrial cancer, a muscle thickness measurement of 7.52 mm in the rectus abdominis is used to estimate the likelihood of complications after surgery, but this threshold correctly identifies only about half of those who will have complications.

For women having open abdominal surgery to treat endometrial cancer, longer surgery times are linked to a slightly higher chance of complications within three months after surgery, even when accounting for age and other variables.

For women having open abdominal surgery to treat endometrial cancer, older age is linked to a higher chance of complications within three months after surgery, even when other factors are taken into account.
