Resum
We aimed to characterise cutaneous melanoma in the elderly and determine its association with poorer prognosis. We studied a prospective cohort of the melanoma population in Catalonia between 2012 and 2016. We compared young patient group (<75 years old) with elderly patient group (>= 75 years old). We included 3009 patients (52.5% women) from 14 centres, with a mean age at diagnosis of 61.1 years. In the >= 75-year-old group there was a predominance of men (53.9% vs. 45.5%, P < 0.001), melanoma was more frequently located in the head and neck area (37.7% vs. 15.5%, P < 0.001) and lentigo maligna melanoma subtype was significantly more frequent (31.4% vs. 11.6%, P < 0.001), as were nodular melanoma and acral lentiginous melanoma (P < 0.001). In older people, Breslow index, the presence of ulceration and mitotic rate were higher than in younger people. Kaplan-Meier survival curves showed longer melanoma-specific survival (MSS) and melanoma-free survival (MFS) in <75-year-old group compared to the elderly group. Cox regression models demonstrated reduced MSS in patients >= 75 years regardless of gender, location, IB, ulceration and lymph node status at diagnosis (HR 1.54, P = 0.013) whereas MFS was not independently associated with elderly when head and neck location was considered. Age appears to be an independent risk factor for MSS but not for MFS. Worse melanoma prognosis in elderly could be explained by factors unrelated to the tumour, such as age-related frailty and comorbidities that limit the access to systemic treatments and, eventually, age-related immune dysfunction.
