6 March 2023Individualized risk estimates for sentinel lymph node biopsy (SLNB) positivity are critical in facilitating thorough decision-making for healthcare providers and patients with melanoma. A tool to calculate pretest probability of sentinel lympph node metastasis in primary cutaneous melanoma (ELMO https://melanoma-sentinel.herokuapp.com) has been developed and validated and was found to have high accuracy compared with other published models and gene expression tests.
23 February 2023According to this recent study there is a lack of knowledge regarding sun exposure and vitamin D. This was associated with suboptimal sun protection practices. Public education is warranted to prevent over-exposure, while supporting natural vitamin D production.
23 February 2023According to this recent study, myeloperoxidase (MPO) contributes to immune checkpoint therapy (ICT) resistance in established melanoma. Repurposing MPO-specific inhibitors may provide a promising therapeutic strategy to enhance ICT response.
23 February 2023While changes in serum protein glycosylation have been previously implicated in a pro-metastatic melanoma behaviour, authors of this recent study show here that they are also associated with response to immune checkpoint inhibitors, opening new avenues for the stratification of patients and the design of adjunct therapies aiming at improving immune response.
23 February 2023According to results from the phase I/IIa RELATIVITY-020 trial, nivolumab and relatlimab had a manageable safety profile and demonstrated durable clinical activity in a proportion of patients with heavily pretreated advanced melanoma with prior progression on anti–PD-(L)1-containing regimens.
21 February 2023This article reviews recent studies that highlight mechanical phenotypic plasticity of melanoma cells as a hallmark of adaptive and non-genetic resistance to treatment and emerging driver in cross-resistance to targeted therapies and immune checkpoints blockade therapies. It also discusses how targeting BRAF-mutant dedifferentiated cells and extracellular matrix-based mechanotransduction pathways may overcome melanoma cross-resistance.
21 February 2023The interaction between nevi, which are congenital or acquired benign melanocytic proliferations, and melanoma is still enigmatic. Authors of this review discuss clinical, histological, molecular, and genetic factors that influence nevus formation and progression to melanoma.
21 February 2023According to this recent study, wearing a device that measured and alerted melanoma survivors to UVR exposure did not result in different sun behaviors, exposure, or sunburns relative to controls. The technology needs refinement before further attempts to assess the effectiveness of self-monitoring UVR exposure.
21 February 2023According to this recent study, the injectable temperature-sensitive PPMSs/DDP@Gel is a promising candidate for the local treatment of melanoma. Anti-tumor studies have shown that the PPMSs/DDP@Gel significantly inhibited tumor growth, prolonged the survival of tumor-bearing mice, and had no obvious toxic side effects on major organs.
20 February 2023According to this recent study, the immunosuppressive drug methotrexate can be linked to an elevated risk of basal cell carcinoma, squamous cell carcinoma and cutaneous malignant melanoma. Patients receiving the drug include those with moderate to severe psoriasis; but in this particular patient group, a risk increase was only observed for basal cell carcinoma.
