New test to screen for ovarian cancer

A new way of screening for ovarian cancer is showing “potential”, according to researchers in the US.

Tumours in the ovaries are hard to detect in the earliest stages meaning it can be too late to treat them effectively by the time they are found.

A trial of 4,051 women, reported in the journal Cancer, showed the method could identify those needing treatment.

Scientists already know that levels of a protein in the blood, called CA125, are often higher with ovarian cancer.

However, it is too unreliable on its own. It misses some patients and tells others they have the cancer when they are actually healthy.

Researchers are now testing the idea of using the blood test to sort patients into risk groups based on levels of CA125. Instead of going straight for surgery, low-risk patients are tested again in a year, medium-risk ones after three months and high-risk patients have an ultrasound scan to hunt for tumours.

There is a survival rate of up to 90% when ovarian cancer is caught early, compared with less than 30% if it is discovered in the later stages.

The US study, at the University of Texas, followed post-menopausal women for 11 years on average.

Annwen Jones, the chief executive at Target Ovarian Cancer, said: “The results of this study are without doubt very positive, and we should take hope from that.

“Early detection of ovarian cancer will be the key to transforming survival rates. However, this study is very small, and there is no guarantee that the results will be replicated on a larger scale.”

A huge study taking place in the UK will give a final verdict on the test when it is completed in 2015.
