Ocul Oncol Pathol 2022 Feb 17;8(1):52-63. Epub 2021 Nov 17.

Department of Biopathologie, Centre Leon Berard, Lyon, France.

The Prognostic Relevance of PMCA4 Expression in Melanoma: Gender Specificity and Implications for Immune Checkpoint Inhibition.

Int J Mol Sci 2022 Mar 19;23(6). Epub 2022 Mar 19.

Department of Thoracic Surgery, University Medicine Essen-Ruhrlandklinik, 45239 Essen, Germany.

PMCA4 is a critical regulator of Ca homeostasis in mammalian cells. While its biological and prognostic relevance in several cancer types has already been demonstrated, only preclinical investigations suggested a metastasis suppressor function in melanoma. Therefore, we studied the expression pattern of PMCA4 in human skin, nevus, as well as in primary and metastatic melanoma using immunohistochemistry. Read More

Identification of New Vulnerabilities in Conjunctival Melanoma Using Image-Based High Content Drug Screening.

Cancers (Basel) 2022 Mar 19;14(6). Epub 2022 Mar 19.

Jules-Gonin Eye Hospital, University of Lausanne, 1004 Lausanne, Switzerland.

Recent evidence suggests that numerous similarities exist between the genomic landscapes of both conjunctival and cutaneous melanoma. Since alterations of several components of the MAP kinases, PI3K/mTOR, and cell cycle pathways have been reported in conjunctival melanoma, we decided to assess the sensitivity of conjunctival melanoma to targeted inhibition mostly of kinase inhibitors. A high content drug screening assay based on automated fluorescence microscopy was performed in three conjunctival melanoma cell lines with different genomic backgrounds with 489 kinase inhibitors and 53 other inhibitors.

Department of Ophthalmology, University Hospital Arnau de Vilanova, Lleida, Spain; School of Medicine, University of Lleida, Lleida, Spain; Biomedical Research Institute of Lleida, University of Lleida, Lleida, Spain. Electronic address:

Primary acquired melanosis (PAM) is acquired conjunctival pigmentation that can give rise to conjunctival melanoma (CM), a malignant tumor of the bulbar and palpebral conjunctiva or the caruncle. Surgical excision is the treatment of choice for this neoplasm. Topical chemotherapy is also used for patients with PAM with atypia or CM and, in patients with recurrent or extensive disease, this may be an important option. Read More

Mutational Characteristics of Primary Mucosal Melanoma: A Systematic Review.

Mol Diagn Ther 2022 03 23;26(2):189-202. Epub 2022 Feb 23.

Université de Reims Champagne-Ardenne, EA 7509: Immune Dysregulation and Tissue Remodelling in Cancer, Autoimmune and Inflammatory Diseases, Reims, France.

Background: Primary mucosal melanomas (PMMs) are rare and clinically heterogeneous, including head and neck (HNMs), vulvovaginal (VVMs), conjunctival (CjMs), anorectal (ARMs) and penile (PMs) melanomas. While the prognosis of advanced cutaneous melanoma has noticeably improved using treatments with immune checkpoint inhibitors (ICIs) and molecules targeting BRAF and MEK, few advances have been made for PMMs because of their poorer response to ICIs and their different genetic profile. This prompted us to conduct a systematic review of molecular studies of PMMs to clarify their pathogenesis and potential therapeutic targets. Read More

New Therapeutic Approaches for Conjunctival Melanoma-What We Know So Far and Where Therapy Is Potentially Heading: Focus on Lymphatic Vessels and Dendritic Cells.

Int J Mol Sci 2022 Jan 27;23(3). Epub 2022 Jan 27.

Department of Ophthalmology, Faculty of Medicine and University Hospital Cologne, University of Cologne, 50937 Cologne, Germany.

Conjunctival melanoma (CM) accounts for 5% of all ocular melanomas and arises from malignantly transformed melanocytes in the conjunctival epithelium. Current therapies using surgical excision in combination with chemo- or cryotherapy still have high rates for recurrences and metastatic disease. Lately, novel signal transduction-targeted and immune checkpoint inhibitors like cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors, programmed cell death protein-1 (PD-1) receptor inhibitors, BRAF- or MEK-inhibitors for systemic treatment of melanoma have improved the outcome even for unresectable cutaneous melanoma, improving patient survival dramatically.
