Malignant melanoma, as a highly aggressive skin cancer, is strongly associated with mutations in serine/threonine protein kinase B-RAF (BRAF, where RAF stands for rapidly accelerated fibrosarcoma). Targeted therapy anti-BRAF small interfering RNA (siBRAF) represents crucial aspect of metastatic melanoma treatment. In this study, an injectable hydrogel platform based on sodium alginate (SA), multifunctions photothermal and Ca2+-overload cell apoptosis, was explored siBRAF carrier therapy. We employed polydopamine nanoparticles (PDAs) core constructed calcium phosphate (CaP) shell via biomineralization (PDA@CaP) to load (PDA@siBRAF/CaP). The pH-sensitive CaP facilitated the release Ca2+ under weakly acidic tumor microenvironment, triggering gelation PDA@siBRAF/CaP-SA localized at sites interruption RAS-RAF-MEK-ERK (MAPK) pathway. Besides, continuous could also lead apoptosis. Moreover, effect PDA regulated kinetics, resulting coordinated therapeutic abilities individual components hydrogels. Consequently, effective inhibition growth metastasis achieved vitro vivo using line B16F10 model, by combining ablation, overload, BRAF silencing. Our work provides proof-of-concept system that simultaneously targets multiple mechanisms involved progression has potential be translated into clinical use

Abstract Purpose Since the introduction of immune checkpoint inhibitors (ICI) and targeted therapies (TT), survival rates metastatic melanoma patients have increased significantly complete remissions are no longer rarities. Consequently, there is an increasing number long-term survivors who not yet been comprehensively characterized. Methods We included entered stage IV between 2014 2017 survived at least 5 years after entering IV. Descriptive statistics were performed to characterize applied systemic therapies, response report which these still alive today. Results 640 University Hospital Tuebingen. Of these, 207 (32%) Details available in 176 (85%). About 90% ( n = 159) time analysis. Median since first diagnosis was 6.0 (range 5–9 years). An impressive majority 146, 83%) receiving therapy evaluation. Complete remission under line seen 36% patients. Conclusion This dataset comprises largest cohort surviving our today, we expect future. Our data indicate need for specific follow-up programs addressing needs survivors.

Increasing melanoma incidence and survival trend shifts with improved melanoma-specific survival between 1990 and 2020 in Sweden

British Journal of Dermatology, Journal Year: 2023, Volume and Issue: 189(6), P. 702 - 709

Abstract Background Melanoma-specific survival (MSS) is heterogenous between stages and highly dependent on the T stage for primary localized disease. New systemic therapies metastatic cutaneous melanoma (CM) have been introduced since 2012 in Sweden. Objectives To analyse incidence MSS time trends 1990 2020 Methods Nationwide, population-based prospectively collected clinico-pathological data invasive CM from Swedish Melanoma Registry (SweMR) were analysed using Kaplan–Meier curves Cox proportional hazard ratios (HRs).

Over the last decade, number of years life lost (YLL) became a popular tool in biostatistics and epidemiology to measure discrepancies expectancy or mortality between cohort patients general population. Its prominence literature is primarily due its ease interpretation because information on cause death not required. Moreover, multi-state models are powerful statistical approach study evolution individuals several "states". Derived from data collected by Belgian Cancer Registry, encompassing 161,007 cases melanoma, thyroid, female breast cancer, three-state (healthy-cancer-death) illness-death model used illustrate how it can be applied cancer registry estimate incidence risk, at different ages diagnosis given that patient survived some after diagnosis.

Abstract Background Cutaneous malignant melanoma (CMM) represents a global public health problem. Epidemiological studies about CMM trends tend to focus on single indicators or lack information tumour characteristics that can help gain more thorough understanding of epidemiology. Objectives To fill this gap, we studied in incidence, mortality and survival over three decades considered sex, age characteristics. Methods Data were obtained for all patients with new diagnosis during 1985–2017 from the population-based cancer registry Granada (Southern Spain) deaths owing Ministry Health Spanish government. Incidence, estimates according group, anatomical site, histological type, Breslow index Clark level. Observed net calculated 1, 3 5 years using Kaplan–Meier Pohar–Perme methods, respectively.

European Journal of Cancer Prevention, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 17, 2024

Malignant melanoma, a highly aggressive skin cancer, though less common, significantly contributes to cancer-related mortality. In the UK, it is of growing concern with an aging population, making crucial analyze historical trends and forecast future burdens. We used Joinpoint regression age-period-cohort models in incidence, prevalence, mortality malignant melanoma UK from 1990 2021. Bayesian model was applied predict disease burden for different age groups by 2030. From 1991 2021, incidence prevalence exhibited distinct temporal patterns: significant upward trend until 2015, particularly pronounced individuals aged 60 older, followed downward after 2015. By 2030, are projected decrease, younger middle-aged populations, expected fall 20.78/100 000 2020 11.90/100 000, 167.80/100 80.13/100 000. Mortality also decrease. However, high-risk groups, especially those 85 above, predicted maintain higher rates. Despite rise, have declined since 2015 continue declining through elderly population remains at risk, underscoring need targeted public health interventions.
