    P53 and MITF/Bcl-2 identified as key pathways in the acquired resistance of NRAS-mutant melanoma to MEK inhibition.
    Eur J Cancer 2017 Jul 21;83:154-165. Epub 2017 Jul 21.
    Laboratory of Oncology and Experimental Surgery, Institut Jules Bordet, Université Libre de Bruxelles, Brussels, Belgium. Electronic address:
    Activating mutations in Neuroblastoma RAS viral oncogene homolog (NRAS) are found in 15-30% of melanomas and are associated with a poor prognosis. Although MAP kinase kinase (MEK) inhibitors used as single agents showed a limited clinical benefit in patients with NRAS-mutant melanoma due to their rather cytostatic effect and high toxicity, their combination with other inhibitors of pathways known to cooperate with MEK inhibition may maximise their antitumour activity. Similarly, in a context where p53 is largely inactivated in melanoma, hyperexpression of Microphthalmia associated transcription factor (MITF) and its downstream anti-apoptotic targets may be the cause of the restraint cytotoxic effects of MEK inhibitors.

    Periprosthetic seroma with false-positive FDG PET-CT reactive nodes mistaken for metastases in a patient previously treated of metastasic melanoma. Potential source of diagnostic errors.
    Int J Surg Case Rep 2017 Jul 8;38:66-68. Epub 2017 Jul 8.
    Department of General Surgery and Digestive Diseases, University Hospital of Araba, Spain. Electronic address:
    Introduction: FDG PET/CT is believed to be crucial in oncology, but its limited specificity represents a challenge. Prosthetic meshes used for repair abdominal defects may lead to false-positives FDG PET/CT uptake, over staging malignancies and inducing inappropriate treatments. A false-positive FDG PET/CT uptake mimicking metastatic disease during the follow-up of a previously treated metastatic melanoma patient is presented. Read More

    PD-1 Inhibitor Therapy: Consensus Statement From the Faculty of the Melanoma Nursing Initiative on Managing Adverse Events
    Clin J Oncol Nurs 2017 Aug;21(4):42-51
    Massachusetts General Hospital Cancer Center.
    Background: Programmed cell death protein 1 (PD-1) inhibitor therapies are now a standard treatment for advanced melanoma and other tumor types. The immune-related adverse events (irAEs) associated with PD-1 inhibitor therapy are drastically different from the AEs associated with chemotherapy. Because these irAEs reflect immune system activation rather than side effects of therapy, nurses should be cognizant of the range of organ systems potentially affected as well as likely clinical presentations.

    Resident memory T cells in the skin mediate durable immunity to melanoma.
    Sci Immunol 2017 Apr;2(10)
    Department of Microbiology and Immunology, Geisel School of Medicine at Dartmouth, Hanover, NH 03755, USA.
    Tissue-resident memory T (TRM) cells have been widely characterized in infectious disease settings; however, their role in mediating immunity to cancer remains unknown. We report that skin-resident memory T cell responses to melanoma are generated naturally as a result of autoimmune vitiligo. Melanoma antigen-specific TRM cells resided predominantly in melanocyte-depleted hair follicles and were maintained without recirculation or replenishment from the lymphoid compartment. Read More

    Melanoma subtypes demonstrate distinct PD-L1 expression profiles.
    Lab Invest 2017 Jul 24. Epub 2017 Jul 24.
    Department of Dermatology, Johns Hopkins University School of Medicine, Bloomberg Kimmel Institute for Cancer Immunotherapy, and Sidney Kimmel Comprehensive Cancer Center, Baltimore, MD, USA.
    PD-L1 expression in the tumor immune microenvironment is recognized as both a prognostic and predictive biomarker in patients with cutaneous melanoma, a finding closely related to its adaptive (IFN-γ-mediated) mechanism of expression. Approximately 35% of cutaneous melanomas express PD-L1, however, the expression patterns, levels, and prevalence in rarer melanoma subtypes are not well described. We performed immunohistochemistry for PD-L1 and CD8 on 200 formalin-fixed paraffin-embedded specimens from patients with acral (n=16), mucosal (n=36), uveal (n=103), and chronic sun-damaged (CSD) (n=45) melanomas (24 lentigo maligna, 13 'mixed' desmoplastic, and 8 'pure' desmoplastic melanomas).

    Fluctuations in routine blood count might signal severe immune-related adverse events in melanoma patients treated with nivolumab.
    J Dermatol Sci 2017 Jul 16. Epub 2017 Jul 16.
    Department of Dermato-Oncology/Dermatology, National Hospital Organization Kagoshima Medical Center, Japan.
    Background: Although nivolumab significantly prolongs survival of metastatic melanoma, about 10% of patients experience severe, even fatal immune-related adverse events (irAEs). Biomarkers to predict irAEs are, therefore, of great interest.

    Objective: We aimed to correlate changes in routine blood count parameters to the occurrence of serious irAEs (grade 3/4 [G3/4] or lung/gastrointestinal [lung/GI] irAEs) in patients with melanoma who were treated with nivolumab. Read More

    Immunotherapy targeting immune check-point(s) in brain metastases.
    Cytokine Growth Factor Rev 2017 Jul 13. Epub 2017 Jul 13.
    Medical Oncology and Immunotherapy, Center for Immuno-Oncology, University Hospital of Siena, Istituto Toscano Tumori, Siena, Italy.
    Immunotherapy with monoclonal antibodies (mAb) directed to different immune check-point(s) is showing a significant clinical impact in a growing number of human tumors of different histotype, both in terms of disease response and long-term survival patients. In this rapidly changing scenario, treatment of brain metastases remains an high unmeet medical need, and the efficacy of immunotherapy in these highly dismal clinical setting remains to be largely demonstrated. Nevertheless, up-coming observations are beginning to suggest a clinical potential of cancer immunotherapy also in brain metastases, regardless the underlying tumor histotype. Read More

    Molecular genetics and targeted therapy of WNT-related human diseases (Review).
    Int J Mol Med 2017 Jul 19. Epub 2017 Jul 19.
    Department of Omics Network, National Cancer Center, Tokyo 104-0045, Japan.
    Canonical WNT signaling through Frizzled and LRP5/6 receptors is transduced to the WNT/β-catenin and WNT/stabilization of proteins (STOP) signaling cascades to regulate cell fate and proliferation, whereas non-canonical WNT signaling through Frizzled or ROR receptors is transduced to the WNT/planar cell polarity (PCP), WNT/G protein-coupled receptor (GPCR) and WNT/receptor tyrosine kinase (RTK) signaling cascades to regulate cytoskeletal dynamics and directional cell movement. WNT/β-catenin signaling cascade crosstalks with RTK/SRK and GPCR-cAMP-PKA signaling cascades to regulate β-catenin phosphorylation and β-catenin-dependent transcription. Germline mutations in WNT signaling molecules cause hereditary colorectal cancer, bone diseases, exudative vitreoretinopathy, intellectual disability syndrome and PCP-related diseases. Read More
