Despite recent improvements in prevention, diagnosis and treatment, vast differences in melanoma burden still exist between populations.,Comparative data can highlight these differences and lead to focused efforts to reduce the burden of melanoma.,To assess global, regional and national melanoma incidence, mortality and disability‐adjusted life year (DALY) estimates from the Global Burden of Disease Study 2015.,Vital registration system and cancer registry data were used for melanoma mortality modelling.,Incidence and prevalence were estimated using separately modelled mortality‐to‐incidence ratios.,Total prevalence was divided into four disease phases and multiplied by disability weights to generate years lived with disability (YLDs).,Deaths in each age group were multiplied by the reference life expectancy to generate years of life lost (YLLs).,YLDs and YLLs were added to estimate DALYs.,The five world regions with the greatest melanoma incidence, DALY and mortality rates were Australasia, North America, Eastern Europe, Western Europe and Central Europe.,With the exception of regions in sub‐Saharan Africa, DALY and mortality rates were greater in men than in women.,DALY rate by age was highest in those aged 75-79 years, 70-74 years and ≥ 80 years.,The greatest burden from melanoma falls on Australasian, North American, European, elderly and male populations, which is consistent with previous investigations.,These substantial disparities in melanoma burden worldwide highlight the need for aggressive prevention efforts.,The Global Burden of Disease Study results can help shape melanoma research and public policy.,What's already known about this topic?,Melanoma incidence and mortality has been assessed in the past for individual countries or world regions.,Melanoma incidence and mortality has been assessed in the past for individual countries or world regions.,What does this study add?,As part of the Global Burden of Disease Study, melanoma burden was estimated at the global, regional and country level for incidence, mortality, prevalence, years lived with disability, years of life lost and disability‐adjusted life years.These estimates can be used to guide prevention and treatment strategies, as well as resource allocation.,As part of the Global Burden of Disease Study, melanoma burden was estimated at the global, regional and country level for incidence, mortality, prevalence, years lived with disability, years of life lost and disability‐adjusted life years.,These estimates can be used to guide prevention and treatment strategies, as well as resource allocation.,Respond to this article,Plain language summary available online
Talimogene laherparepvec (T-VEC) is an oncolytic immunotherapy designed to induce tumor regression of injected lesions through direct lytic effects, and of uninjected lesions through induction of systemic antitumor immunity.,In this study, we describe the patterns and time course of response to T-VEC from the phase III OPTiM trial of 436 patients with unresected stages IIIB-IV melanoma.,Lesion-level response analyses were performed based on the type of lesion (injected or uninjected cutaneous, subcutaneous, or nodal lesions; or visceral lesions [uninjected]), and the best percentage change from baseline of the sum of products of the longest diameters was calculated.,Patients randomized to T-VEC (n = 295) who experienced a durable response (continuous partial or complete response for ≥6 months) were evaluated for progression prior to response (PPR), defined as the appearance of a new lesion or >25 % increase in total baseline tumor area.,T-VEC resulted in a decrease in size by ≥50 % in 64 % of injected lesions (N = 2116), 34 % of uninjected non-visceral lesions (N = 981), and 15 % of visceral lesions (N = 177).,Complete resolution of lesions occurred in 47 % of injected lesions, 22 % of uninjected non-visceral lesions, and 9 % of visceral lesions.,Of 48 patients with durable responses, 23 (48 %) experienced PPR, including 14 who developed new lesions only.,No difference in overall survival was observed, and median duration of response was not reached in patients with PPR versus those without PPR.,Responses in uninjected lesions provide validation of T-VEC-induced systemic immunotherapeutic effects against melanoma.,PPR did not negatively impact the clinical effectiveness of T-VEC.,The online version of this article (doi:10.1245/s10434-016-5286-0) contains supplementary material, which is available to authorized users.
