Partners play critical role in melanoma exams

But a new Northwestern Medicine study shows the benefits of a partner frequently checking for troublesome moles based on training to do so far outweigh the embarrassment.

Study participants who received skin examination training caught far more mole irregularities than those in the control group. They also grew more confident performing the examinations.

Common places to develop potentially fatal melanoma include hard-to-see areas where it is difficult to apply sunscreen such as behind the ears and knees, the top of the head and around the swimsuit line on a woman's bottom.

"These aren't parts of the body that most females like to have examined by their male partner, but at some point, they realized they're just looking at the moles, not the cellulite," said lead author Dr. June Robinson, research professor of dermatology at Northwestern University Feinberg School of Medicine. "We found as long as the benefit is strong enough, it overcomes whatever potential embarrassment there might be between the partners."

Partners of patients who had been previously diagnosed with early stages of melanoma performed frequent skin self-self examinations (SSEs) on the patient over the course of the two-year study.

As the study progressed, a partners' confidence in his or her ability to find irregular moles increased, as did the trust in one another to successfully identify the irregularities.

The study was published in JAMA Dermatology.

Participants were asked every four months to indicate on a five-point scale how much they agreed or disagreed with the following two statements: "It is very embarrassing to have my partner help examine my skin," and "I am very comfortable having my partner help examine my skin."

Based on their responses, melanoma patients and their partners eventually had no problems being checked for irregular moles by their partners, Robinson said.

"In that discussion back and forth, they make a judgment call and agree on it," said Robinson, who is the editor of JAMA Dermatology. "As they each grow more confident in their decision-making, the trust between them becomes stronger. When the trust is there, there's no issue with embarrassment."

Also noteworthy, the study found mole observations men and women make complement one another. Men tend to notice mole border irregularities better than women, whereas women tend to see color variations in the moles better than men.

"The pairs realize, 'We need to help each other here,'" Robinson said. "If he sees borders better and she sees colors better, those two heads are better than one when finding the irregularities."

The 395 participants in the study had previously been diagnosed with early stages of melanoma (0 to IIB) and had surgically removed irregular moles. They were recruited from outpatient clinics of the Northwestern Medicine and were 21 to 80 years old.

The control group consisted of 99 participants who did not receive SSE training. The remaining participants received training in one of three forms: from a physician, by reading a take-home handbook or by listening to exercises on a tablet. The pairs performed SSEs on one another every month or every other month to check for mole irregularities, and assigned a score to common features of the mole: 1 if the mole looked normal, 2 if they were unsure and 3 if it looked abnormal.
