Uterine sarcoma condition is most commonly treated by radical hysterectomy. If cancer has spread beyond the uterus, radiation, chemotherapy, and hormonal therapy may be used. If detected in its early stages, survival rates for uterine sarcoma are 66% after 5 years.
As with endometrial carcinomas, the prognosis is influenced by the grade and type of the adenocarcinoma, being poorest with serous differentiation. MMMTs are highly malignant; a stage I tumor has an expected five-year survival rate of 50%, while the overall five-year survival rate is less than 20%. [1] Staging of uterine MMMTs is as follows: [3]
A leiomyosarcoma (LMS) is a rare malignant (cancerous) smooth muscle tumor. [1] The word is from leio- 'smooth' myo- 'muscle' and sarcoma 'tumor of connective tissue'. The stomach, bladder, uterus, blood vessels, and intestines are examples of hollow organs made up of smooth muscles where LMS can be located; however, the uterus and abdomen are the most common sites.
Uterine cancer effects approximately 3.1% of females during their lifetime. [8] Uterine cancer resulted in 45,000 deaths worldwide in 1990, with this number increasing to 58,000 deaths in 2010. [21] North America and Northern Europe have the highest rates of uterine cancer.
In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1] Below is an incomplete list of age-adjusted mortality rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
In the United States there has been an increase in the 5-year relative survival rate between people diagnosed with cancer in 1975-1977 (48.9%) and people diagnosed with cancer in 2007-2013 (69.2%); these figures coincide with a 20% decrease in cancer mortality from 1950 to 2014. [8]
The prognosis for low-grade endometrial stromal sarcoma is good, with 60–90% five-year survival. High-grade undifferentiated endometrial sarcoma (HGUS) has a worse prognosis, with high rates of recurrence and 25% five-year survival. [55] HGUS prognosis is dictated by whether or not the cancer has invaded the arteries and veins.
Sarcoma: Adolescents and young adults often fare worse than young children with the same histologic type of sarcoma. In Ewing sarcoma, survival is inversely related to age and tumor size diagnosis. Adolescents and young adults with rhabdomyosarcoma have a much lower survival rate at 5 years than children, 27% compared with 61%. [15]
