Questionnaires were completed by 5,950 self-selected participants who voluntarily attended the Western Australian Lions Cancer Institute's targeted skin cancer screening clinics during the period 1996-2003. A risk assessment technique was used to identify individuals at high risk of developing melanoma. Provisional diagnoses of suspicious lesions were given at the screening by a medical specialist. Suspicious lesions were later matched with histopathologically confirmed malignant melanomas reported to the Western Australia Cancer Registry. Fifty-seven per cent of attendees were female. The mean age of attendees was 53 years. The yield of suspicious malignant melanomas detected was 24.7 per 1,000 participants screened; the yield of confirmed malignant melanomas detected was 3.0 per 1,000 participants screened. Persons over 50 years of age were three times more likely to have a histopathologically confirmed malignant melanoma detected at the screening than those younger than 50 years (p = 0.049). The yield of confirmed melanomas detected by the Lions Cancer Institute is among the highest reported by a skin cancer screening program. This may have been attributable to the risk assessment technique used by the program. A free community skin cancer screening program that targets high-risk individuals can detect melanomas.

Seventy skin cancer screening clinics were held by the Lions Cancer Institute in predominantly rural areas of Western Australia between 1996 and 2003. Participants were self-selected and voluntary, responding to an advertisement seeking people at 'high-risk' of melanoma. The Lions Cancer Institute skin screening clinics targeted participation by individuals with three or more of the established risk factors for skin cancer/melanoma. Questionnaires collecting information on the self-report of nine risk factors were completed by 5950 participants who were screened for melanoma between 1996 and 2003. The number and type of risk factors, and of provisionally diagnosed and histopathologically confirmed malignant melanomas were measured. Of 5950 participants, 18 histopathologically confirmed malignant melanomas were detected. A participant's total number of risk factors showed some association with the provisional melanoma diagnosis given at the time of screening. No relationship, however, was observed between the number of risk factors and a melanoma that was histopathologically confirmed after screening. The risk factor method is effective in selecting a 'high risk' population, but does not seem to have high value in predicting who will be diagnosed with melanoma as a result of screening. Further studies are needed to verify this finding owing to the rarity of melanoma and the small number of confirmed melanomas in this study.

Members of the community responded to newspaper advertisements to attend free skin cancer screening events. This report presents preliminary results obtained from the methods development programme. Seventeen screening clinics were conducted in Perth (4) and country towns (14) in Western Australia between January 1991 and October 1993. The participants were interviewed and given promotional literature and their personal profiles were determined. A total body skin examination was performed by a specialist plastic surgeon and any suspicious lesions were recorded and, if necessary, recommendations for further treatment was documented. The number of individuals screened was 3397. Of these, 572 patients were referred to general practitioners for further medical attention of suspicious lesions, 79 patients were clinically diagnosed as having suspicious pigmented skin lesions (13.8% of total lesions and 2.3% of total sample screened). Of these, 53 individual patient pathology reports were obtained. Four invasive malignant melanomas and two in situ melanomas arising in Hutchinson's melanotic freckles were detected. Debates concerning the efficacy of screening for skin cancer have recently received great attention from many medical disciplines. However, as yet the effectiveness of population based skin cancer screening programmes have not been adequately evaluated with randomized controlled studies. The study reported here provides some findings that may be used to enhance future screening studies.
