Further experience of public education for the early diagnosis of malignant melanoma in Leicestershire

Abstract

Publicity campaigns alerting the public to the need for early attention to malignant melanoma (MM) were conducted in Leicestershire, England during the summers of 1987, 1988 and 1989. There was a marked, and statistically significant, rise in the number of referrals with good prognosis MMs in the period immediately after the first campaign. In the 2 subsequent years, despite further publicity campaigns, the number of MMs diagnosed per week remained lower than the postpublicity peak of 1986/87. The postpublicity rise was less marked in 1987/88 and 1988/89. In the next year (1989/90), in which there was no publicity campaign, the total number of MMs seen was higher than in 1988/89. Numbers of MMs seen per week remained relatively steady throughout the year. There was again no publicity in 1990/91, and the total number of MMs diagnosed was about the same as in the previous year. There was a rise in the number of MMs seen per week in what would have been the postpublicity period of this year. The initial results would be consistent with the initial postpublicity rise in numbers of MMs seen being made up of lesions seen 'early', that is, in 1986/87 and 1987/88. Since these lesions were seen earlier than they would have been had there been no publicity, the number of MMs seen in 1988/89 was lower than it would otherwise have been and the publicity effort appeared to have less effect. By 1989/90 and 1990/91 this effect seems to have been wearing off. It may be that, at least in low MM incidence areas like the UK, it is better to pulse public education for the early diagnosis of melanoma rather than to use annual or continuous campaigns. However, longer-term experience, and the pooling of data between centres will be necessary to test this conclusion.
