The most common adverse events seen were anemia, fatigue, and thrombocytopenia. In patients with metastatic EAC, single agent niraparib as second line therapy is not an effective option.

Luminal subtype independent immune-enrichment in inflammatory breast cancer based on commercially available tumor portrait. (SABCS 2024)
Over half of cases with luminal molecular phenotype demonstrate immune-enriched TME, suggesting a potentially significant role for immunotherapy in these patients and expanded efforts in this arena. Using the BG Tumor PortraitTM assay, low TMB and MSS was present in the majority of IBC samples evaluated in spite of numerous studies showing common DNA repair mutations. HER2 expressing cases demonstrated a predominantly immune-desert phenotype and further study of the clinical relevance and validation of this is warranted.

RAD51 Paralogs and RAD51 Paralog Complexes BCDX2 and CX3 Interact with BRCA2. (PubMed, bioRxiv)
Furthermore, the interaction with RAD51B is dependent upon an FxxA motif located on a surface exposed region of the CTD. Our study has identified novel interactions between the RAD51 paralogs and BRCA2 and further demonstrated that a previously unrecognized FxxA motif located within a mobile element of RAD51B is critical for the interaction.

We identified CpGs in Rev, Ipmk, Rad51b, Fgfr2, Fgfr3 and Ctnnb1 that may serve as potential biomarkers for SCC risk and could be helpful for the early detection and prevention of SCC. Further investigations are necessary to determine the biological functions and clinical significance of these CpGs.

Mechanism of BCDX2-mediated RAD51 nucleation on short ssDNA stretches and fork DNA. (PubMed, Nucleic Acids Res)
Moreover, while mutants defective in ssDNA binding retain the ability to bind branched DNA substrates, they still facilitate RAD51 loading onto reversed replication forks. Our study provides mechanistic insights into how the BCDX2 complex stimulates the formation of BRCA2-independent RAD51 filaments on short stretches of ssDNA present at ssDNA gaps or stalled replication forks, highlighting its role in genome maintenance and DNA repair.

RAD51B-AS1 promotes the malignant biological behavior of ovarian cancer through upregulation of RAD51B. (PubMed, J Zhejiang Univ Sci B)
Thus, RAD51B-AS1 promotes the malignant biological behaviors of OC and activates the protein kinase B (Akt)/B cell lymphoma protein-2 (Bcl-2) signaling pathway, and these effects may be associated with the positive regulation of RAD51B expression. RAD51B-AS1 is expected to serve as a novel molecular biomarker for the diagnosis and prediction of poor prognosis in OC, and as a potential therapeutic target for disease management.

Beyond BRCA: what does assessment of additional homologous recombination and mismatch repair genes in primary and metastatic prostatic adenocarcinoma add? (ECP 2024)
We reported the frequency of HRD and MMR somatic mutations in a large real-world cohort of consecutive primary and metastatic PCs, providing a realistic estimate of the proportion of patients that could benefit from PARP or immune checkpoint inhibitors. Analysis of HR genes beyond BRCA1 and BRCA2 significantly increased the pool of patients that would be eligible for PARP inhibitor trials. BRCA1/BRCA2 and MMR mutations were more frequent in metastatic lesions suggesting these gene defects to be strong metastatic drivers.

Prospective Study of Homologous Recombination Repair Gene Mutation Prevalence in Patients With Advanced Prostate Cancer From Latin America: Challenges and Future Approaches. (PubMed, JCO Precis Oncol)
Despite the study's limitations, to our knowledge, PROSPECT was the first attempt to describe the prevalence of HRRm in patients with PC from LAC. Notably, the germline HRRm prevalence in this study was inferior to that observed in North American and European populations. The somatic HRR testing barriers identified are being addressed by several projects to improve access to HRR testing and biomarker-based therapies in LAC.

Targeted DNA sequencing of high-grade serous ovarian carcinoma reveals association of TP53 mutations with platinum resistance when combined with gene expression. (PubMed, Int J Cancer)
Targeted DNA sequencing of TP53 combined with transcript quantification may contribute to the concept of precision oncology of HGSC. Future studies should explore targeting the p53 pathway based on specific mutation types and co-analyze the expression and mutational profiles of other key cancer genes.

Treatment patterns and outcomes in metastatic castration-resistant prostate cancer patients with and without somatic or germline alterations in homologous recombination repair genes. (PubMed, Ann Oncol)
Worse outcomes were observed for mCRPC patients in the BRCA subgroup compared with non-BRCA subgroups, either HRR non-BRCA or non-HRR. Despite its heterogeneity, the HRR non-BRCA subgroup presented worse outcomes than the non-HRR subgroup. Screening early for HRR mutations, especially BRCA1/2, is crucial in improving mCRPC patient prognosis.

Adenoid cystic carcinoma of the Bartholin's gland is underpinned by MYB- and MYBL1- rearrangements. (PubMed, Gynecol Oncol)
AdCC-BGs constitute a convergent phenotype, whereby activation of MYB or MYBL1 can be driven by the MYB::NFIB fusion gene or MYBL1 rearrangements. Our observations further support the notion that AdCCs, irrespective of organ site, constitute a genotypic-phenotypic correlation. Assessment of MYB or MYBL1 rearrangements may be used as an ancillary marker for the diagnosis of AdCC-BGs.

Sarcomas with RAD51B Fusions are Associated with a Heterogeneous Phenotype. (PubMed, Mod Pathol)
Our results expand the spectrum of sarcomas with RAD51B-fusions, demonstrating variable clinical presentations, morphologic spectrum, and fusion partners. These tumors have a predilection for a uterine location, with either LMS, PEComa or undifferentiated phenotypes, and are associated with an aggressive clinical course.
