Melanoma: Screenings Vs. Self-Exams

July 20, 2011

(Ivanhoe Newswire) ““ Physician-based screening for melanoma is associated with higher rates of detecting the cancer than self-examinations, according to this study.

The disease-specific survival rate for advanced-stage melanoma is poor, so detecting the cancer in an earlier stage is the best means to ensure a favorable prognosis, according to background information in the article. Previous research has demonstrated that patients find most melanomas, and that those lesions tend to be thicker than physician-detected lesions. “Working on the premise that physician-based screening and patient self-screening are vital in the detection of early melanoma,” the authors were quoted as saying.

Ivanka Kovalyshyn, D.O., from MSKCC, and colleagues conducted a retrospective review of patient records and biopsy logs from two MSKCC pigmented lesion specialists from January 1998 through December 2008. The institution’s PLC serves patients at high risk for developing melanoma, so each patient visit involves a total body skin examination, and patients are given brochures instructing them how to perform skin self-examination (SSE). Researchers divided the group into “established” patients, who had been treated at MSKCC’s PLC for three months or more, and “new” patients who were new to the practice.

A total of 527 melanomas were identified in 394 patients. Among the established group, lesions tended to be thinner, more often detected in the in situ phase and less likely to exhibit negative prognostic attributes. Physicians detected 82 percent of melanomas in established patients and 63 percent in new patients. The overall patient-detection rate was 18 percent, and most lesions found by patients were detected because of change in appearance.

“Although we recognized that high-risk patients may have more frequent physician skin examinations and may be more vigilant in performing SSE, we strongly believe that the PLC setting contributes to earlier detection of melanoma in our cohort,” the authors said. They do note that the patient’s role in melanoma recognition is important as well. “Therefore,” they concluded, “it is crucial to emphasize that a combined strategy of physician detection and patient participation must continue to be implemented to ensure early melanoma diagnosis.”
