Immunotherapy is a treatment strategy that has demonstrated survival benefit for metastatic melanoma. Ipilimumab and nivolumab are examples of immunotherapy, in which monoclonal antibodies antagonize cytotoxic T-lymphocyte-associated protein 4 and programmed death-ligand 1 receptors, respectively, resulting in upregulation of the host immune response to cancer cells. There is increasing recognition of immune-mediated adverse events associated with immune therapies in patients with cancer. We present a case report of a patient who developed Miller Fisher syndrome associated with these therapies for metastatic melanoma along with a discussion of its management.

Background: Although rare, melanoma confined to the dermis or subcutaneous tissue without evidence of a primary cutaneous site should provoke consideration of melanoma of unknown primary. This diagnosis carries a favorable prognosis when compared with cutaneous metastatic melanoma. Several hypotheses have been proposed for how melanoma of unknown primary develops, two of which were considered in our patient case: (1) spontaneous regression of the primary tumor following metastasis or (2) the traumatic implantation of ectopic melanocytic cells in other tissues, such as the subcutaneous tissue.

Background/aim: In a tongue-submandibular lymph node (SLN) metastasis model, the cystine/glutamate transporter solute carrier family 7, member 11 (Slc7a11), also known as xCT, was found to increase in lymphatic endothelial cells (LECs) within SLNs prior to melanoma cell metastasis. However, the precise mechanism by which xCT influences LECs remains unclear. This study aimed to explore the role of xCT in primary cultured LECs.

Background: Metastasis is the major cause of cancer-related mortality. The premetastatic niche is a promising target for its prevention. However, the generality and cellular dynamics in premetastatic niche formation have remained unclear.

Objective: It has been shown that the CYFIP2 (Cytoplasmic FMR1-interacting protein 2) gene is apoptosis p53-dependent and is associated with poor prognosis in malignant tumors such as gastric cancer and other and cervical cancer. However, the prognostic potential of CYFIP2 in pancreatic cancer remains unclear. In this work, we first explain the great potential of CYFIP2 malignant progression from a broader perspective (pan-cancer) and confirm its oncogenic value in pancreatic cancer.

Methods: This multi-methods study included NCDB analyses and a cancer registry staff survey. Trends in recurrence data missingness from 2004 to 2021 and multivariable analyses of factors associated with missingness from 2017 to 2021 were evaluated for 4,568,927 patients with non-metastatic cancer.
