Comparative Study of Head and Neck Mucosal Melanoma in 66 patients vs. 226 patients with Cutaneous Melanoma: A survival analysis

Abstract

Sixty-six patients (22%) had HNMM and 226 (78%) HNCM and the higher prevalence was seen in females with a similar distribution amongst the two diagnoses (p=0.8).

Symptoms were present in all patients with HNCM and in only 15% of patients with HNMM (p=0.000).

Lymph node involvement at diagnosis was present in 51% of HNMM vs. 33% of HNCM (p=0.007) and were bilateral in 44% of HNMM while in HNCM they were only ipsilateral (p=0.000).

Metastatic disease at diagnosis was similar in both groups (p=0.9).

Relapses were more frequent in the HNMM group in ~70% of the cases compared with 23% in HNCM group (p=0.000).

When comparing HNCM vs. HNMM, Overall Survival is similar, without statistical difference.
