Women diagnosed with cutaneous melanoma have a survival advantage compared to men, which has been hypothesized to be due to difference in behavior and/or biology (sex hormones).,It remains controversial whether this advantage is dependent on age or stage of disease.,We sought to compare melanoma‐specific survival between females in pre, peri, and postmenopausal age groups to males in the same age group, adjusting for stage of disease.,This is a retrospective population‐based cohort study using the Surveillance, Epidemiology, and End Results (SEER) database.,Patients diagnosed from 1 January 1992 through 31 January 2011 with primary invasive cutaneous melanoma were included in our cohort.,Melanoma‐specific survival was the main outcome studied.,Of the 106,511 subjects that were included, 45% were female.,Females in all age groups (18-45, 46-54, and ≥55) with localized and regional disease, were less likely to die from melanoma compared to males in the same age group.,Among patients with localized and regional disease, the relative risk of death due to melanoma increased with advancing age at diagnosis; this increase was more pronounced among females than males.,In contrast, we observed no female survival advantage among patients with distant disease and no effect of age on relative risk of death from melanoma.,Females with localized and regional melanoma have a decreased risk of death compared to males within all age groups.,Our data show no differences in survival between men and women with metastatic melanoma, indicating that the influence of sex on survival is limited to early stage disease but not confined to pre or perimenopausal age groups.
Uveal melanoma (UM), a rare cancer of the eye, is distinct from cutaneous melanoma by its etiology, the mutation frequency and profile, and its clinical behavior including resistance to targeted therapy and immune checkpoint blockers.,Primary disease is efficiently controlled by surgery or radiation therapy, but about half of UMs develop distant metastasis mostly to the liver.,Survival of patients with metastasis is below 1 year and has not improved in decades.,Recent years have brought a deep understanding of UM biology characterized by initiating mutations in the G proteins GNAQ and GNA11.,Cytogenetic alterations, in particular monosomy of chromosome 3 and amplification of the long arm of chromosome 8, and mutation of the BRCA1-associated protein 1, BAP1, a tumor suppressor gene, or the splicing factor SF3B1 determine UM metastasis.,Cytogenetic and molecular profiling allow for a very precise prognostication that is still not matched by efficacious adjuvant therapies.,G protein signaling has been shown to activate the YAP/TAZ pathway independent of HIPPO, and conventional signaling via the mitogen-activated kinase pathway probably also contributes to UM development and progression.,Several lines of evidence indicate that inflammation and macrophages play a pro-tumor role in UM and in its hepatic metastases.,UM cells benefit from the immune privilege in the eye and may adopt several mechanisms involved in this privilege for tumor escape that act even after leaving the niche.,Here, we review the current knowledge of the biology of UM and discuss recent approaches to UM treatment.
