Background: Esthesioneuroblastoma (ENB) is a rare neoplasm of the sinonasal tract. Currently, the optimal treatment includes maximal resection combined with radiotherapy and/or chemotherapy. Although ENBs often recur and have an aggressive clinical course, spinal metastases are extremely rare and the underlying molecular mechanisms are poorly understood.

Studies have reported that pre-existing autoimmunity increases the risk of irAEs, but it remains unknown which clinical factors are linked to auto-immune disorders in cancer patients. This study aimed to evaluate if the prevalence of autoimmune diseases varied by specific cancer history and advanced age.

Adoptive cell therapies with chimeric antigen receptor (CAR) engineered T cells (CAR-T) and immune checkpoint inhibition (ICI)-based cancer immunotherapies have lately shown remarkable success in certain tumor types. CAR-T cell-based therapies targeting CD19 can now induce durable remissions as well as prolong disease-free survival of patients with CD19 positive treatment refractory B cell malignancies and ICI-based therapies with humanized monoclonal antibodies against the T cell inhibitory receptors CTLA-4 and PD-1 as well as against the PD-1 ligand, PD-L1, can now achieve durable remissions as well as prolongation of life of a sizeable fraction of patients with melanoma and Hodgkin's lymphoma and non-small cell cancers. Most importantly, these immuno-therapeutic treatment modalities have raised the possibility of achieving long-term "containment" as well as "cures" for certain types of cancer.

OM can compromise nutrition, require opioid analgesics and hospitalization for pain control, and lead to treatment interruptions. Based on the role of inflammatory pathways in OM pathogenesis, we investigated effect of cyclooxygenase-2 (COX-2) inhibition on severity and morbidity of OM.

Because the incidence of melanoma is increasing at a very fast pace in the elderly and there is a rapid expansion of the aging population, a large number of elderly patients with metastatic melanoma will be encountered in clinical practice. As a result, significant burden is expected to be placed on health care resources as effective treatment of this condition is sought.

Using melanoma as a model and melanoma related Mart-127-35 epitope specific T cell receptor (TCR) engineered T cells as a tool we compared the T cell responses from young and elderly to the Mart-127-35 epitope, ex vivo. We also compared the natural Treg (nTreg) activities and the expression of a number of genes associated with immune response by quantitative real-time reverse Transcription Polymerase Chain Reaction (qRTPCR) in formalin fixed primary melanomas, in situ.

Unfortunately, once metastatic to the visceral organs, CM is usually refractory to the presently available treatment modalities, resulting in uniformly poor outcomes in patients. Educating susceptible populations about the risk of developing CM has played an important role in preventive strategies despite the fact that benefits of primary skin screening are controversial.

Cutaneous melanoma (CM) is a highly curable skin cancer of melanocytes if diagnosed early. Unfortunately, its invasion into the deeper dermis increases the risk of it spreading to the lymph nodes and distant organs. Spread of metastatic melanoma (MM) to other organs is among one of the most dangerous conditions that is almost uniformly fatal for the majority of patients with the currently available treatment modalities.

We report a young patient with stage I testicular seminoma followed by close surveillance after radical orchidectomy, who developed hilar and subcarinal lymphadenopathy more than two years after the original diagnosis. A mediastinal biopsy was consistent with noncaseating granuloma with no evidence of tumor.

Immune strategies will be important in designing effective treatment of melanoma because it is a highly immunogenic tumor. Aging, however, is associated with dysregulation of the immune system and is likely to affect the success of melanoma treatment in the elderly population.
