ON THIS PAGE: You will find information about the number of women who are diagnosed with ovarian, fallopian tube, and peritoneal cancer each year. You will also read general information about surviving these diseases. Remember, survival rates depend on several factors. Use the menu to see other pages.
This year, an estimated 21,750 women in the United States will be diagnosed with ovarian cancer, and the vast majority of these are high-grade serous ovarian cancers (HGSC), which begin in a fallopian tube. From 2007 to 2016, the number of new cases decreased annually by 1.6%. One reason for this decrease may be related to the decline in use of hormone replacement therapy following a 2002 publication linking hormone replacement therapy to breast cancer risk with later data showing an association with ovarian cancer. The decrease may also be related to more women having their fallopian tubes removed.
It is estimated that 13,940 deaths from these diseases will occur this year. Combined, cancer of the ovaries, fallopian tubes, and peritoneum are the fifth most common cause of cancer-related death in women in the United States. The death rate declined by more than 2% each year from 2008 to 2017. This decline in death rate is primarily due to advances in treatment.
The 5-year survival rate tells you what percent of women live at least 5 years after cancer is found. Percent means how many out of 100. The 5-year survival rate for women with all types of ovarian, fallopian tube, and peritoneal cancers is 48%.
However, the rate varies widely depending on the woman’s age, as well as the stage, cell type, and grade of the cancer. Survival rates are also improved when debulking surgery is performed by a gynecologic oncologist instead of a gynecologist or general surgeon (see Types of Treatment). The 5-year survival rate for women younger than 65 is 60%, compared with 31% for those 65 and older.
If ovarian and fallopian tube cancers are diagnosed and treated before they spread outside the ovaries and tubes, the general 5-year survival rate is 92%. Approximately 15% of women with epithelial ovarian and fallopian tube cancer are diagnosed at this stage. If the cancer has spread to surrounding tissues or organs, the 5-year survival rate is 75%. If the cancer has spread to a distant part of the body, the 5-year survival rate is 29%. Approximately 59% of women are diagnosed at this stage.
It is important to remember that statistics on the survival rates for women with ovarian, fallopian tube, and peritoneal cancer are an estimate. The estimate comes from annual data based on the number of women with these cancers in the United States. Also, experts measure the survival statistics every 5 years. So the estimate may not show the results of better diagnosis or treatment available for less than 5 years. Talk with your doctor if you have any questions about this information.
