Hemangioblastoma in Hereditary Leiomyomatosis and Renal Cell Cancer Syndrome: a phenotypic overlap between VHL and HLRCC Syndromes
We present a case study of hemangioblastoma occurrence in a Hereditary Leiomyomatosis and Renal Cell Cancer Syndrome patient and propose it as possible evidence of a phenotypic overlap between von Hippel Lindau and Hereditary Leiomyomatosis and Renal Cell Cancer Syndromes due to their overlapping role in the biochemical regulation of hypoxia inducible factor alpha.
Over the past several years, a wave of new cancer immunotherapy agents referred to as immune checkpoint inhibitors (ICIs) have transformed the standard of care for patients with cancer. ICIs are most commonly used in advanced cancers with palliative intent and recently as frontline therapy for some cancers. These new agents have been shown to extend overall survival (OS) and progression free survival (PFS) in patients with lung cancer, melanoma, Hodgkin lymphoma, renal cell carcinoma, urothelial carcinoma, Merkel cell carcinoma, head and neck cancer, and more.
Conclusion: XGP is a diagnostic and therapeutic dilemma. Partial Nephrectomy may be appropriate in management of XGP in select cases. PMID: 31976820 [PubMed - as supplied by publisher]
Conclusions: Adrenal SBRT for oligometastatic disease is a feasible, noninvasive option with excellent LC and minimal toxicity. Lesions in close proximity to radiosensitive organs may benefit from dynamic patient positioning and selective simultaneous-integrated boost techniques to allow for dose escalation, while also limiting toxicity risks.
Conclusion: Combining RT with pembrolizumab in pretreated mRCC is well-tolerated and appears to have comparable efficacy with single-agent nivolumab.
Conclusion: M6A RNA methylation regulators play important roles in the initiation and progression of ccRCC and provide a novel sight to understand m6A RNA modification in ccRCC.

Clear-cell renal cell carcinoma (ccRCC) is the most common and lethal subtype of kidney cancer. VHL and PBRM1 are the top two significantly mutated genes in ccRCC specimens, while the genetic mechanism of the VHL/PBRM1-negative ccRCC remains to be elucidated. Here we carried out a comprehensive analysis of single-cell genomic copy number variations (CNVs) in VHL/PBRM1-negative ccRCC. Genomic CNVs were identified at the single-cell level, and the tumor cells showed widespread amplification and deletion across the whole genome. Functional enrichment analysis indicated that the amplified genes are significantly enriched in ca...
Conclusion: Our study demonstrated that the aberrant expression of CDCA gene family members plays an indispensable role in tumorigenesis. PMID: 31955607 [PubMed - as supplied by publisher]

Orafai, Amirhossein SahebkarAbstractAutophagy is a conserved “self-eating” recycling process which removes aggregated or misfolded proteins, or defective organelles, to maintain cellular hemostasis. In the autophagy-lysosome pathway (ALP), clearance of unwanted debris and materials occurs through the generation of the autophagosome, a complex of double-membrane bounded vesicles that form around cytosolic cargos and catabolize their contents by fusion to lysosomes. In tumor...
