Survival rates can be calculated by different methods for different purposes. The ovarian cancer survival rates
presented here are based on the relative survival rate. The relative survival rate measures the survival of cancer patients in comparison to the general population to estimate the effect of cancer. The overall 5-year relative survival rate for ovarian cancer
for 1996-2002 was 44.7 percent. The 5-year relative survival rates by race and sex were:
- 44.2 percent for white women
- 39.5 percent for black women.
How Stage Affects Survival
The stage of ovarian cancer a woman has plays a role in her ovarian cancer prognosis
. Based on historical data:
- 19 percent of ovarian cancer cases are diagnosed while the cancer is still confined to the primary site (localized stage)
- 7 percent of ovarian cancer cases are diagnosed after the cancer has spread to regional lymph nodes or directly beyond the primary site
- 68 percent of ovarian cancer cases are diagnosed after the cancer has already metastasized (distant stage)
- 7 percent of ovarian cancer cases had staging information that was unknown.
The corresponding 5-year relative ovarian cancer survival rates were:
- 93.1 percent for localized
- 69.0 percent for regional
- 29.6 percent for distant
- 23.3 percent for unstaged.
Statistics on Lifetime Risk
Based on rates from 2001-2003, 1.44 percent of women (or 1 in 69 women) born today will be diagnosed with ovarian cancer at some point during their lifetime. These statistics are called the lifetime risk of developing cancer.
