Scientists work on new test for ovarian, endometrial cancers

Could the Pap smear, which is already commonly used to detect cervical cancer, also be used to find endometrial and ovarian cancers?  A small study suggests that may be possible in the future.

Scientists at Johns Hopkins have found that cervical fluid collected during a routine Pap smear can be used to detect both types of cancers by using a genome sequencing test called the “PapGene.”

Researchers administered the test on a small group of samplings, and found the procedure accurately detected all 24 endometrial cancers, or cancer of the lining of the uterus.  However, they were only able to find nine of 22, or 41%. of ovarian cancers.  FULL POST

Why many would-be bone marrow, blood stem cell donors back out

Upon being identified as potential bone marrow or blood stem cell donors, many people choose not to participate. As result, patients with blood cancers go without life-saving treatments.

About 40% of whites and 60% of nonwhites are no longer available for whatever reason to donate when contacted for confirmatory testing by blood sample, according to data from the National Marrow Donor Program and Be The Match. Surveys from Be The Match also suggest that about 10-23% of donors are unavailable specifically because they choose to opt out.  Why? That's the question researchers attempted to answer in a recent study.

"The most consistent factor associated with opting-out of the registry across all race/ethnic groups was ambivalence about donation - doubts and worries, feeling unsure about donation, wishing someone else would donate in one's place," writes Galen Switzer, a professor of medicine and psychiatry at the University of Pittsburgh, in the study, published in December in the journal Blood.
