Three proteins may be used to diagnose ovarian cancer, according to a new study released on Wednesday.
Researchers analyzed blood samples from 34 women with ovarian cancer and 70 women without the disease to evaluate six proteins identified as potential indicators of ovarian cancers.
Garnet Anderson of the Fred Hutchinson Cancer Research Center in Seattle and colleagues found that levels of three of the six proteins began to increase slightly in patients with ovarian cancer three years before diagnosis.
Anderson wrote in the Journal of the National Cancer Institute that the elevated levels aren't really what we'd probably define as abnormal until within the last year before diagnosis of ovarian cancer.
Ovarian cancer is rare, but can be deadly. There is no simple and reliable screening program to test for the medical condition in women who do not have symptoms.
When the cancer id diagnosed in its early stage, the five-year survival rate can be as high as 93 percent, according to the American Cancer Society.
Therefore, a screening method that can detect ovarian cancer in its early stage is desired.
The researchers wanted a screening method just that can be used like the PSA test
for prostate cancer. However, the prostate specific antigen is by itself not a reliable indicator.
