  • A new blood test could catch ovarian cancer in its earliest, and most treatable, stage

  • according to a new study.

  • The new method was devised by researcher Karen Lu at the University of Texas' MD Anderson

  • Cancer Center in Houston.

  • She examined the potential of a two-stage ovarian cancer screeningthe blood test,

  • looking for a change the tumor-marking blood protein, CA125, followed by a transvaginal

  • ultrasound. (Via Science World Report)

  • HealthDay reports that unlike breast, cervical or colon cancer, there is no reliable screen

  • test to detect the disease. They call it "a silent killer ... By the time a woman knows

  • she has it, the cancer is often advanced and the outlook grim."

  • Her team monitored more than 4,000 postmenopausal women over an 11-year period, with all subjects

  • receiving an annual CA125 blood test. They noticed that on an average nearly 5.8 percent

  • of women were detected with intermediate risk each year. (Via Sky News)

  • Based on the ultrasound exams, 10 women underwent surgery. Four had invasive ovarian cancer,

  • two had malignant ovarian tumors, one suffered endometrial cancer and three had benign ovarian

  • tumors. (Via Medical News Today)

  • And while the results are being considered groundbreaking, Lu doesn't think they're practice-changing

  • just yet, writing in a statement:

  • "However, our findings suggest that using a longitudinal [or change over time] screening

  • strategy may be beneficial in post-menopausal women with an average risk of developing ovarian

  • cancer." (Via The Guardian)

  • The trial results are being published in Cancer, the journal of the American Cancer Society,

  • and Lu says she believes the finding will raise hopes that were dashed by a similar,

  • earlier study that deemed the screening unsuccessful.

  • According to the Centers for Disease Control and Prevention, each year about 20,000 U.S.

  • women are diagnosed with ovarian cancer. It is the eighth most common cancer and the fifth

  • leading cause of cancer death among U.S. women.

  • And the National Cancer Institute estimates there will be more than 22,000 new cases of

  • ovarian cancer in the U.S. this year, resulting in more than 14,000 deaths.

  • It's unknown whether the findings could be applied to younger women, but the methodIt's unknown whether the findings could be applied to younger women, but the method

  • is undergoing additional testing in the U.K. That study will involve 300,000 women, and

  • is due to report in 2015.
