In the older literature survival rates have been given as 35–50% for stage I–II and 0–15% for stage III and IV uterine papillary serous carcinoma, [4] More recently it was reported that forty-two percent of 138 patients were found disease-free at five years.
Uterine clear-cell carcinoma is staged like other forms of endometrial carcinoma at time of surgery using the International Federation of Gynecology and Obstetrics (FIGO) cancer staging system 2009. [4] IA Tumor confined to the uterus, no or < 1 ⁄ 2 myometrial invasion IB Tumor confined to the uterus, > 1 ⁄ 2 myometrial invasion
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.
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]
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]
Over a 45-years span — between 1975 and 2020 — improvements in cancer screenings and prevention strategies have reduced deaths from five common cancers more than any advances in treatments ...
Rarely, serous tumors arise from within the uterus, notably uterine serous carcinoma, which typically arises in postmenopausal women. Rarely, serous tumors arise from other parts of the peritoneum, including serous primary peritoneal carcinomas. Even more rarely they arise in other body locations, such as the lungs. [1]
According to the Cleveland Clinic, this rare cancer spreads by secreting mucin, a component of mucus, inside a person's abdomen, causing it to fill up with a jelly-like substance.
