Melanoma and intellectual disability: do prognostic factors at diagnosis differ from general population?

Résumé

Background Few melanoma cases are reported in individuals with intellectual disability (ID), and prognostic factors at diagnosis are unknown in this population. This work was designed to investigate whether prognostic factors at diagnostic are different in patients with ID compared with a general population. Methods Melanoma cases retrieved from Hérault's Tumour Registry (HTR) from 1995 to 2015 were cross-referenced against a list of adult patients with ID, living in Hérault. Major prognostic factors were compared with those in non-ID melanoma patients included in HTR and in patients followed by Montpellier University Hospital and included in the Réseau pour la Recherche et l'Investigation Clinique sur le Mélanome (RIC-Mel) database. Results Ten melanoma cases in individuals with ID were identified and compared with 3804 non-ID melanoma cases in HTR and 1024 non-ID melanoma cases included in RIC-Mel. Mean Breslow thickness at diagnosis was 4.6 mm in melanoma cases among those with ID versus 1.89 mm in HTR (P = 0.109) and 2.36 mm in RIC-Mel (P = 0.156). Stage at diagnosis was superior to stage IIB in 42.9% of ID cases versus 11.4% of non-ID cases in HTR (P < 0.05) and 8.5% in RIC-Mel (P < 0.05). Conclusions Melanomas in patients with ID had less favourable prognostic factors at diagnosis, including higher Breslow thickness and more advanced stage, than melanomas in non-ID patients. These adverse prognostic factors indicate a later diagnosis in this population, leading to a poorer prognosis. This work underlines the need to improve melanoma screening among individuals with ID.
