    Surgically treated papillary renal cell carcinoma shows distinct prognosis and needs specific prognostic models for counseling, follow-up and high-risk patient identification. Our goal is to summarize and compare currently recommended models

    Renal cell carcinoma and viral infections: A dangerous relationship?

    Virus-related cancers in humans are widely recognized, but in the case of renal cancer, the link with the world of viruses is not clearly established in humans, despite being known in animal biology. In the present review, we aimed to explore the literature on renal cell carcinoma (RCC) for a possible role of viruses in human RCC tumorigenesis and immune homeostasis, hypothesizing the contribution of viruses to the immunogenicity of this tumor. A scientific literature search was conducted using the PubMed, Web of Science, and Google Scholar databases with the keywords “virus” or “viruses” or “viral infection” matched with (“AND”) “renal cell carcinoma” or “kidney cancer” or “renal cancer” or “renal carcinoma” or “renal tumor” or “RCC”. The retrieved findings evidenced two main aspects testifying to the relationship between RCC and viruses: The presence of viruses within the tumor, especially in non-clear cell RCC cases, and RCC occurrence in cases with pre-existing chronic viral infections. Some retrieved translational and clinical data suggest the possible contribution of viruses, particularly Epstein-Barr virus, to the marked immunogenicity of sarcomatoid RCC. In addition, it was revealed the possible role of endogenous retrovirus reactivation in RCC oncogenesis, introducing new fascinating hypotheses about this tumor’s immunogenicity and likeliness of response to immune checkpoint inhibitors

    Efficacy and safety of long-term tolvaptan treatment in a patient with SCLC and SIADH

    Hyponatremia frequently occurs in patients with cancer and is mostly due to a syndrome of inappropriate antidiuresis caused by ectopic secretion of antidiuretic hormone (SIADH). Small cell lung cancer presents with SIADH in approximately 11%-15% of cases. Recently, a new class of drugs, vasopressin V2-receptor antagonists (vaptans), emerged as a promising treatment for SIADH, but efficacy and safety data in cancer patients are lacking. We present a case of SIADH, heralding small cell lung cancer and persisting after apparent complete remission of primary tumor following chemotherapy/radiotherapy, in a patient who underwent long-term treatment with tolvaptan without any serious adverse effects
