Screening for cutaneous malignant melanoma: a feasibility study

• To study two different procedures for inviting subjects to screening for malignant melanoma, and to study the role of specially trained nurses as primary examiners.Methods—The study was carried out in Stockholm county and comprised 5000 randomly selected men and women aged 40 to 60, of whom 2500 were invited with a personal invitation letter and with a set time of appointment and 2500 were sent a questionnaire and instructions for self examination of the skin. To test the nurses' competence, a survey was made, comparing the judgments of skin examination between nurses and doctors.Results—1654 (66%) of those invited for a skin examination took part. 1507 (60%) replied in the questionnaire group, of whom 1024 (41%) requested and attended a subsequent skin examination. Of the subjects attending from both groups, the nurses judged 9% v 11% as having skin lesions suggesting malignant melanoma, whereas the two doctors referred 4% v 3% of the subjects for surgical biopsy. Two malignant melanomas were detected, both of them in the questionnaire group. In the study of nurses' screening competence, both nurses and doctors equally judged one case out of 19 as having a lesion suspicious for malignant melanoma.Conclusions—When the questionnaire method was used the results were achieved with one third fewer skin examinations, but it is difficult to conclude whether one of the procedures is better than the other. The results also indicate that nurses can be trained to be the primary examiners in a melanoma screening programme.
