Similar to other polyomaviruses, MCPyV encodes early T antigen genes, a viral oncogene required for MCC tumor growth. To identify the unique oncogenic properties of MCPyV, we analysed the gene expression profiles in human spontaneously immortalized keratinocytes (NIKs) expressing the early genes from five distinct human polyomaviruses (PyVs), including MCPyV. A comparison of the gene expression profiles revealed 28 genes specifically deregulated by MCPyV.

Utikal Merkel cell carcinoma is a deadly skin cancer, which in the majority of cases is caused by the Merkel cell polyomavirus (MCPyV). The viral small T antigen is regarded as the dominant oncoprotein expressed in the tumor cells. We used genomic screening of copy number aberrations along with transcriptomic analysis to investigate regions with amplification that harbor differentially expressed genes. We identified YTHDF1, a protein that is a reader of N6-methyladenosine (m6A) RNA modifications, to have high copy gains and to be highly expressed in Merkel cell carcinoma. Importantly, we identified the presence of ...

CONCLUSIONS: Our explorative study identified new tumor tissue-based molecular characteristics associated with response to anti-PD-1/PD-L1 therapy in MCC. These observations warrant further investigations in larger patient cohorts to confirm their potential value as predictive markers. PMID: 31932494 [PubMed - as supplied by publisher]

Merkel cell carcinoma (MCC) is a rare but highly malignant skin cancer with neuroendocrine features and a propensity for both local recurrence and regional lymph node metastases. The prognosis is poor, and the 5-year overall survival rate is very low (0%-18%) for advanced stage MCC 1. Despite a high malignancy rate, some cases have a good prognosis, including cases with spontaneous regression (1.7%-3.0%) 2. Even after spontaneous regression, however, MCC may recur at distant sites 3. Therefore, a precise prognosis is difficult to make.

The treatment of malignant neoplasm of the nasal upper airway presents a high morbidity rate for patients. Radiotherapy is one therapeutic option. The patient undergoing head and neck radiotherapy treatment needs to perform a dental examination before, during, and after cancer treatment. A male African American patient, 52 years of age with a history of being a former smoker and alcoholic for 12 years, was diagnosed in 2005 with an oral squamous cell carcinoma in the left lateral lingual surface, clinical stage of T2 N0 M0, and treated with head and neck surgery with negative cervical lymph nodes.

CONCLUSION: irPR features are consistent across tumor types and treatment settings. Standardized, pan-tumor immune-mediated pathologic response criteria (irPRC) are defined and associated specimen-handling considerations are described. Future, prospective studies are merited to validate irPRC in larger datasets and to associate pathologic features with long-term patient outcomes. PMID: 31672770 [PubMed - as supplied by publisher]

Authors: Kamińska-Winciorek G, Cybulska-Stopa B, Lugowska I, Ziobro M, Rutkowski P Abstract The introduction of immunotherapy into the treatment of cancer patients has revolutionised the oncological approach and significantly improved patient survival. The key drugs are immune checkpoint inhibitors (CPIs), whose mechanism of action is to elicit immune response against cancer cell antigens. Three types of CPIs are currently used and approved: an anti-CTLA-4 antibody, ipilimumab; anti-PD-1 antibodies, nivolumab and pembrolizumab; and anti-PD-L1 antibodies: atezolizumab, avelumab and durvalumab. CPIs have been widely...
