Machine Learning-Based Pathomics Model to Predict the Prognosis in Clear Cell Renal Cell Carcinoma. (PubMed, Technol Cancer Res Treat)
The machine learning-based pathomics model effectively predicts the OS of ccRCC patients and differentiates between subtypes. The critical roles of the immune-related gene CTLA4 and the PI3K-Akt, HIF-1, and MAPK signaling pathways offer new insights for further research on the molecular mechanisms, diagnosis, and treatment strategies for ccRCC.

Tumor infiltrating T-cells and loss of expression of SWI/SNF genes in varying stages of clear cell renal cell carcinoma. (PubMed, Pathol Res Pract)
Loss of PBRM1, SMARCA2/BRM, and SMARCA4/BRG1 expression is significantly associated with ccRCC progression, with PBRM1 loss prevalent in advanced stages and SMARCA2/BRM and SMARCA4/BRG1 in earlier stages. ARID1A and SMARCA2/BRM losses correlate with reduced CD8 + counts and stage-specific CD4 + infiltration, highlighting their potential as biomarkers for disease progression and immunotherapeutic response.

CDC20-Mediated Selective Autophagy Degradation of PBRM1 Affects Immunotherapy for Renal Cell Carcinoma. (PubMed, Adv Sci (Weinh))
As a result, the efficacy of anti-PD-1 immunotherapy is enhanced, leading to improved overall survival rates in syngeneic mouse tumor models. Overall, this finding suggest the clinical application of PB1-p62 and provide a novel approach for enhancing the effectiveness of immunotherapy in RCC patients with wild-type PBRM1.

Hepatoid thymic carcinoma in a polycythemia vera patient treated with ropeginterferon Alfa-2b: Clinical, histopathological and molecular correlates. (PubMed, Pathol Res Pract)
Whole exome sequencing revealed loss of function mutations in TP53, STK11, PBRM1, SMAD3, FN1, NTRK1, and FANCD2, as well as gain of function mutations in MTOR, BCL11A and COL1A1, along with amplification of CCND3 and MDM2. This mutational landscape halfway between thymic carcinoma (TP53, PBRM1) and hepatoid variant carcinoma of other sites (STK11) suggests that, at some point during carcinogenesis, a switch occurred from an epithelial thymic phenotype to a hepatoid-like one.

Evaluation of PD-L1 expression in PBRM1-altered clear cell renal cell carcinoma. (PubMed, Urol Oncol)
Although our study did not establish a correlation between PBRM1 mutations and PD-L1 expression, it demonstrated that the occurrence of PBRM1-altered ccRCC with PD-L1 expression is not uncommon. Therefore, the presence of PBRM1 alterations may challenge the use of PD-L1 IHC as a predictive marker for PD-L1 blockade in ccRCC.

Differences in mutations across tumour sizes in clear-cell renal cell carcinoma. (PubMed, BJU Int)
Large and small ccRCCs are genomically different. Aggressive mutations, namely, SETD2, BAP1, and CDKN2A loss, are rarely observed in small ccRCCs and are observed more frequently in larger tumours. However, when present in tumours ≤7 cm, SETD2 mutations and CDKN2A loss were still independently associated with invasive disease, metastasis, worse survival, and recurrence after resection, after controlling for size.

A Scoping Review of Population Diversity in the Common Genomic Aberrations of Clear Cell Renal Cell Carcinoma. (PubMed, Oncology)
Studying the genetic aberrations that frequently occur in different regions gives insight into what current research lacks. When more genomic landscape research arises, precision therapy, risk calculators, and artificial intelligence may help better prognosticate and individualize treatment for those at risk for ccRCC. Provided the scarcity of existing data, and the rising prevalence of ccRCC, more studies must be conducted at the clinical level.

PBRM1 presents a potential ctDNA marker to monitor response to neoadjuvant chemotherapy in cervical cancer. (PubMed, iScience)
In vitro, PBRM1 knockdown promoted resistance to cisplatin through boosting STAT3 signaling in cervical cancer cells, while it sensitized tumor cells to poly-ADP-ribose-polymerase inhibitor olaparib. These findings suggest that mutant PBRM1 is a potential ctDNA marker of emerging resistance to NACT and of increased sensitivity to olaparib, which warrants further clinical validation.

PBRM1 loss is associated with increased sensitivity to MCL1 and CDK9 inhibition in clear cell renal cancer. (PubMed, Front Oncol)
Increased MCL1 activity has been described as a resistance mechanism to Sunitinib and Everolimus, two approved agents for ccRCC. PRT2527, a potent CDK9 inhibitor which depletes MCL1, was similarly efficacious in monotherapy and in combination with Sunitinib in PBRM1-loss cells. Taken together, these findings suggest PBRM1 loss is associated with MCL1i sensitivity in ccRCC and provide rationale for the evaluation of PRT1419 and PRT2527 for the treatment for PBRM1-deficient ccRCC.

Fanconi anemia complementation group C (FANCC) gene association with hereditary and sporadic renal tumors (RT). (ASCO-GU 2024)
Somatic and germline mutations in FANCC occur in an exceedingly small subset of clinically advanced RT but at similar rate to other cancers. RT with inactivated FANCC do not appear to have a different GA landscape from RT with wild-type FANCC. The high frequency of predicted germline status during somatic testing with FANCC alterations suggests the importance of further workup with confirmatory germline testing as it may affect counseling for other family members.

PBRM1 mutation and WDR72 expression as potential combinatorial biomarker for predicting the response to Nivolumab in patients with ccRCC: a tumor marker prognostic study. (PubMed, Aging (Albany NY))
The present study indicated that high expression of WDR72 may indicate a good prognosis of patients treated with Nivolumab and WDR72 expression combined with PBRM1 mutation could be more persuasive to predict the response for ICT in ccRCC patients.

an increased incidence of KDM5C mutations, which, in common with increased PBRM1 alterations, is also associated with a favourable outcome; and 5. angiogenetic biomarkers are increased in tumour tissue, while inflammatory biomarkers are decreased, which explains the good response to TKI therapy and lack of sensitivity to IT.

Genomic profiling of tissue and blood predicts survival outcomes in patients with resected pleural mesothelioma. (PubMed, Eur J Cancer)
Tissue TMB and MAF, blood TMB, and specific mutations correlated with outcomes in patients with resected PM and should be further studied to validate their role as prognostic biomarkers and potentially predictive factors for combinations with immune-checkpoint inhibitors. This suggest that molecular profiling could identify longer survivors in patients with resected PM.

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.

A hypothesis generating analysis of the role of chromosome 3p-related genes as predictors for immunocombinations in metastatic renal cell carcinoma (mRCC) (EMUC 2023)
Our hypothesis-generating data highlights the need of an integrated evaluation of 3p-related genes as promising biomarkers in RCC. Further and wider studies are required.

MUC1-C INTEGRATES CHRONIC ACTIVATION OF INTERFERON PATHWAYS WITH CHROMATIN REMODELING IN TREATMENT RESISTANCE OF TRIPLE-NEGATIVE BREAST CANCER (SABCS 2023)
In support of these results, targeting MUC1-C in wild-type BRCA1/2 TNBC cells enhanced carboplatin-induced DNA damage and loss of self- renewal capacity. In addition, MUC1-C was necessary for DNA damage resistance, self-renewal and tumorigenicity of olaparib-resistant BRCA1-mutant TNBC cells...As one example, an allogeneic anti-MUC1-C CAR T cell using MAb 3D1 sequences is undergoing Phase I evaluation for the treatment of MUC1-C-expressing cancers (NCT05239143: P-MUC1C-ALLO1 Allogeneic CAR-T Cells in the Treatment of Subjects with Advanced or Metastatic Solid Tumors). In addition, anti-MUC1-C huMAb3D1-MMAE ADCs are under development by the NCI NExT Program for IND-enabling studies and performing early phase clinical trials in patients with TNBC.
