AbstractIn recent years the incidence of melanoma in elderly patients has increased with an unfavorable oncologic outcome due not only to immune deterioration but also to greater aggressiveness of the tumor. The aim of this study was to evaluate the behavior of cutaneous melanoma in relation to age. A consecutive series of cases with melanoma operated in a reference center in the period 2001-2013 was included. The sample was divided into two groups according to the age. Group 1 (G1): under 65 years and Group 2 (G2): over 65 years. Histopathological variables and oncologic outcomes were compared between the two groups. Three hundred and eighty eight patients were operated. They belonged to G1 241 (62%) and to G2 147 (38%). Both groups were homogeneous with respect to the histological type of melanoma. Group 2 had thicker melanomas (Breslow > 4 mm 19% vs. 7%, p < 0.005) and higher rates of ulceration (37% vs. 20%, p: 0.007) and distant metastases (stage IV 11% vs. 3%, p 0.01). There was no difference between groups regarding nodal involvement. With a mean follow up of 45 (6-98) months throughout the series, recurrence of disease was higher in group 2 (26% vs. 17%, p: 0.03), but the specific mortality showed no significant difference (9.5% vs. 5.3%, p: 0.12). In conclusion, cutaneous melanoma in patients over 65 years is more aggressive with higher rates of local recurrence and distant metastases.
