Table 2 Statements on the prevalence of uterine sarcoma in presumed fibroids

From: Options on fibroid morcellation: a literature review

Statements

Evidence

The incidence of leiomyosarcoma is 0.64/100,000 per year

 

The prevalence of sarcoma in a presumed fibroid is 0.14 % (1:700) with a range from 0.49 % (1:204) to 0.014 % (1:7,400). This large range renders more prospective data collection necessary.

C

The risk of sarcoma in presumed fibroids is positively related to age, although the majority of sarcomas—in absolute numbers—will be in the fourth decade. Below the age of 40 sarcoma in a presumed fibroid is extremely rare.

C

Based on age, an accurate assessment of the risk of sarcoma in patients with presumed fibroids is not possible although a global estimation (intermediate risk versus low risk) could be made
