Ovarian cancer is resistant to immunotherapy, and this is influenced by the immunosuppressed tumor microenvironment (TME) dominated by macrophages. Resistance is also affected by intratumoral heterogeneity, whose development is poorly understood. To identify regulators of ovarian cancer immunity, we employed a spatial functional genomics screen (Perturb-map), focused on receptor/ligands hypothesized to be involved in tumor-macrophage communication.

Article Synopsis
  • - Oncocytic renal neoplasms pose significant diagnostic challenges, yet are generally nonaggressive, prompting discussion about the necessity of differentiating emerging subtypes like eosinophilic solid and cystic renal cell carcinoma and others.
  • - A survey of 63 urologic pathologists revealed that many encounter complex oncocytic tumors frequently, with 70% agreeing that eosinophilic solid and cystic renal cell carcinoma should be recognized as a distinct category, while opinions were more divided on other types.
  • - Diagnostic approaches varied among pathologists, with 60% hesitant to diagnose oncocytoma through needle biopsies, and a near split on the routine use of immunohistochemistry; common genetic testing was

Article Synopsis
  • * The survey received an 85% response rate from 98 uropathologists, revealing strong agreement on distinguishing between luminal and basal UC types, but varied opinions on the importance of certain genetic tests like FGFR3 and TERT promoter mutations.
  • * Most uropathologists acknowledged the aggressive nature of tumors with micropapillary features and favored further evaluation and specific molecular testing for aggressive subtypes, indicating a need for improved consensus in UC classification and treatment strategies.

Article Synopsis
  • Clear cell renal cell carcinoma (ccRCC) is the most prevalent type of kidney cancer, and a study analyzed the genomes of 778 ccRCC patients to uncover its mutational characteristics.
  • * The research identified key driver genes and emphasized the significance of epigenetic regulation, which may open up new treatment possibilities.
  • * Findings included that patients with more structural copy number alterations had worse outcomes, while those with VHL mutations fared better; this work supports the idea that immune response plays a role in prognosis and could influence immunotherapy approaches.*
