Cutaneous melanoma in the Maltese Islands: 2000-2004.
This study aimed to, prospectively, over the 5-year period 2000-2004, accurately determine features of cutaneous melanoma in the Maltese Islands. Data from clinicians were supplemented by histology reports, and where necessary, histology slides were reviewed. Information collected included demographic details including age and gender, anatomical site, Clark's level, Breslow thickness and clinico-pathological melanoma type. During the study period the age-standardised (European Standard Population) rates for invasive melanoma were 8.81 per 100,000 (males) and 7.29 per 100,000 (females) and increased with age. By the end of the study, information on 166 cases of primary invasive cutaneous malignant melanoma were collected. The commonest site affected in males was the trunk (54%) and in females the lower limbs (41%). Overall, 33.8% of invasive melanomas had a Breslow thickness >1.5mm. The initial melanoma excision was performed by a dermatologist in 68.2% and plastic surgeon in 20.8%. More cases presented in late spring and summer, particularly in females. Melanoma incidence in Malta is lower than that in high-incidence countries and northern Europe and is similar to that in southern Europe. However, incidence appears to be increasing and a relatively high proportion of patients present with thick lesions emphasising the importance of continued efforts to diagnose cases earlier.
