Low Exposures to Amphibole or Serpentine Asbestos in Germline Bap1-mutant Mice Induce Mesothelioma Characterized by an Immunosuppressive Tumor Microenvironment. (PubMed, Cancer Res Commun)

Chrysotile induced a more profound immune tumor response than crocidolite in Bap1-mutant mice by upregulating CD39/CD73-adenosine and Ccl2/Ccr2 pathways and recruiting more M2 macrophages, which together contributed to an immunosuppressive tumor microenvironment. Interrogation of human MM RNA-seq data revealed interconnected immunosuppressive pathways consistent with our mouse findings.

The Pediatric and Young Adult Choroidal and Ciliary Body Melanoma Genetic Study, A Survey by the European Ophthalmic Oncology Group. (PubMed, Invest Ophthalmol Vis Sci)

Males had a more favorable survival and disomy 3, and the absence of a BAP1 mutation in the tumor tissue predicted the most favorable metastasis-free survival. A BAP1 germline pathogenic variant was identified in one patient (1%), and a somatic variant based mainly on immunohistochemistry in 13 (42%).

Quantification of eosinophilic area and its potential molecular feature in clear cell renal cell carcinoma. (PubMed, Jpn J Clin Oncol)

The quantification of the eosinophilic feature serves as a robust predictor of clinical prognosis in clear cell renal cell carcinoma. Furthermore, the manifestation of this feature may be linked to BAP1 mutations and the down-regulation of Erythroblast Transformation-Specific-Related Gene in clear cell renal cell carcinoma. Significantly, the expression levels of Erythroblast Transformation-Specific-Related Gene manifest as an exemplary prognostic marker, providing exceptional predictive accuracy for the clinical prognosis in clear cell renal cell carcinoma.

In the current article, we focus on some new histological features, attempting to explain and link them to certain mechanisms of tumor development, including senescence, endoreplication, endocycling, asymmetric cytokinesis, entosis and others. In light of the morphological and molecular findings observed in BIM, we postulated that this entity unmasks a fine mechanism of tumor in which both clonal/stochastic and hierarchical model can be unified.

Genomic Landscape of Pleural Mesothelioma and Therapeutic Aftermaths. (PubMed, Curr Oncol Rep)

Similarly, the association between mutational profile and the immune microenvironment or immunotherapy response is not well characterised. Further research into the link between tumour mutational profile and response to therapy is critical for identifying targetable vulnerabilities and stratifying patients for therapy.

Interdependence of Molecular Lesions That Drive Uveal Melanoma Metastasis. (PubMed, Int J Mol Sci)

Several gene expression events that show a non-significant association with outcome when considering single features become significant when analyzing combinations of risk features indicating additive action. The independence of risk factors is consistent with a random risk model of UM metastasis without an obligatory sequence.

Morphological characteristics of SETD2-mutated locally advanced clear cell renal cell carcinoma: Comparison with BAP1-mutated clear cell renal cell carcinoma. (PubMed, Ann Diagn Pathol)

These findings justify the use of molecular testing to detect these mutations, especially when we encounter high-grade ccRCC. Detecting SETD2 and BAP1 mutation in ccRCC is useful for risk stratification and proper therapeutic strategy.

Genomic alterations are infrequent but occur in malignant SCTs as well as a subset of benign SCTs. Molecular analysis of additional malignant SCTs is necessary to identify recurring and/or potentially actionable targets.

Next-generation sequencing of uveal melanoma with clinical and histological correlations: Prognostic value of new mutations in the PI3K/AKT/mTOR pathway. (PubMed, Clin Exp Ophthalmol)

BAP1 is the most solid biomarker of a poor prognosis in UM and mutations can be detected using NGS. SF3B1 is associated with the spindle cell subtype of UM, which gives it probably a favourable prognostic value. Our study suggests that mutations in DHX9 and PDK1 can have prognostic value. These potential biomarkers are related to the PI3K/AKT/mTOR pathway and makes them candidates for developing new directed therapies.

Molecular markers associated with survival in grade 3 meningioma (SNO 2023)

The associations between reduced OS and TERTp mutations and CDKN2A/B status remained significant after adjusting for Simpson resection grade. Our findings support using TERTp mutations and CDKN2A/B status for prognostication in grade 3 meningioma.

Mutational profile of primary clear cell renal cell carcinoma predicts recurrence and potential selection for adjuvant therapy (EMUC 2023)

Presence of somatic “non-VHL” mutations in PBRM1, BAP1, SETD2, KDM5C, ATM, MTOR, or PTEN genes in 451 TCGA ccRCC patients was associated with a significantly shorter disease-free survival (DFS) compared to those with unaltered tumors (q=0.01). Conclusions These findings support the prognostic value of “non-VHL” mutations including PBRM1, BAP1, SETD2, KDM5C, ATM, MTOR, and PTEN in primary ccRCC tumors as surrogates of earlier recurrence and potential selection for adjuvant therapy.
