Prevalence of Uterine Leiomyosarcoma: how many people are affected worldwide, differences by sex and region, with sources.
Uterine leiomyosarcoma is a rare and aggressive form of cancer that arises from the smooth muscle cells of the uterus. It accounts for approximately 1-2% of all uterine malignancies. Although it is considered a rare cancer, its prevalence varies depending on several factors such as age, race, and genetic predisposition.
Age: Uterine leiomyosarcoma primarily affects women in their 40s and 50s, with the average age of diagnosis being around 55 years.
Race: Studies have shown that uterine leiomyosarcoma is more common in African American women compared to women of other races.
Genetic Predisposition: Certain genetic conditions, such as hereditary leiomyomatosis and renal cell cancer syndrome, have been associated with an increased risk of developing uterine leiomyosarcoma.
Due to its rarity, there is limited data on the exact prevalence of uterine leiomyosarcoma. However, it is estimated that the annual incidence rate is approximately 0.64 cases per 100,000 women. It is important to note that early detection and prompt treatment are crucial for improving outcomes in patients with uterine leiomyosarcoma.
