Homologous recombination (HR) and DNA damage repair (DDR) somatic alterations in metastatic colorectal cancer (mCRC): results from the comprehensive genomic profiling (CGP) trial FPG500 (AIOM 2024)

Background : Treatment (tx) of MSS/MMRp mCRC relies mainly on oxaliplatin (oxa)- or irinotecan-based doublet chemotherapy regimens, with no biomarker reported so far, allowing the selection of one tx over the other. HR-DDRa is associated with MSI-H or TMB-H. Pts with MSS HR-DDRa tumors benefit from oxa-based first line treatment. Longer FU, allowing mature OS data, and wider cohorts are warranted.

Pathogenic variants in cancer susceptibility genes predispose to Ductal Carcinoma In situ of the breast. (PubMed, Clin Cancer Res)

The enrichment of PVs in ATM, BRCA1, BRCA2, CHEK2 and PALB2 among women with DCIS suggests that multigene panel testing may be appropriate for women with DCIS. Elevated risks of contralateral breast cancer in carriers of PVs in high penetrance genes with DCIS confirmed the utility of testing for surgical decision-making.

Functional Analysis of BARD1 Missense Variants on Homology-Directed Repair in Ovarian and Breast Cancers. (PubMed, Mol Carcinog)

These findings collectively suggest that these seven missense BARD1 variants are likely pathogenic and may respond well to cisplatin-olaparib combination therapy. This study not only enhances our understanding of BARD1's role in DNA damage repair but also offers valuable insights into predicting therapy responses in patients with specific BARD1 missense mutations.

Survival advantage of native and engineered T cells is acquired by mitochondrial transfer from mesenchymal stem cells. (PubMed, J Transl Med)

Artificial MitoT prevents STS-induced apoptosis of human CD3+ T cells by interfering with the caspase pathway. Furthermore, we observed that MitoT confers protection to apoptosis induced by electroporation in MitoTpos CAR T-engineered cells, potentially improving their metabolic fitness and resistance to environmental stress. These results widen the physiological perspective of organelle-based therapies in immune conditions while offering potential avenues to enhance CAR-T treatment outcomes where their viability is compromised.

Alterations in the expression of homologous recombination repair (HRR) genes in breast cancer tissues considering germline BRCA1/2 mutation status. (PubMed, Breast Cancer Res Treat)

In cancer tissues harbouring either BRCA1 or BRCA2 germline mutations, no significant differences in expression were observed at the mRNA level of any tested HR genes, except BRCA1. However, the significant differences observed in BRCA1 expression between germline BRCA1mut, germline BRCA2mut and BRCA1/2wt tissues may indicate a compensatory mechanism at the mRNA level to mitigate the loss of BRCA1 function in the cells.

Multi-gene panel analysis in BRCA1/2-negative patients suspected of hereditary breast and ovarian cancer syndrome: Real-world data from a single institution. (PubMed, J Obstet Gynaecol Res)

Additional MGP testing of germline genes associated with hereditary cancer predisposition syndrome in BRCA1/2-negative breast and ovarian cancer patients revealed PVs in non-BRCA1/2 breast cancer- and ovarian cancer-related genes in 7.7% of breast cancer and 11% of ovarian cancer. Therefore, additional testing may provide useful information for subsequent risk-reducing surgery and surveillance in BRCA1/2-negative patients.

Homologous recombination (HR) and DNA damage repair (DDR) somatic alterations in metastatic colorectal cancer (mCRC): Results from the comprehensive genomic profiling (CGP) trial FPG500 (ESMO 2024)

Background: Treatment (tx) of MSS/MMRp mCRC relies mainly on oxaliplatin (oxa)- or irinotecan-based doublet chemotherapy regimens, with no biomarker reported so far, allowing the selection of one tx over the other. HR-DDRa is associated with MSI-H or TMB-H. Pts with MSS HR-DDRa tumors benefit from oxa-based first line treatment. Longer FU, allowing mature OS data, and wider cohorts are warranted.

Germline BARD1 variants predispose to mesothelioma by impairing DNA repair and calcium signaling. (PubMed, Proc Natl Acad Sci U S A)

Our study elucidated mechanisms of BARD1 activity and revealed that heterozygous germline BARD1 mutations favor the development of mesothelioma and increase the susceptibility to asbestos carcinogenesis. These mesotheliomas are significantly less aggressive compared to mesotheliomas in asbestos workers.

FLT1 activation in cancer cells promotes PARP-inhibitor resistance in breast cancer. (PubMed, EMBO Mol Med)

Moreover, PARPi-resistant tumor cells can be readily re-sensitized to PARPi by targeting Flt1 either genetically (Flt1-suppression) or pharmacologically (axitinib). Importantly, a retrospective series of breast cancer patients treated with PARPi demonstrated shorter progression-free survival in cases with FLT1 activation at pre-treatment. Our study therefore identifies FLT1 as a potential therapeutic target in PARPi-resistant, BRCA1/2-mutant breast cancer.

Rare pathogenic structural variants show potential to enhance prostate cancer germline testing for African men. (PubMed, Res Sq)

Notable African-specific loss-of-function gene candidates include DNA damage repair MLH1 and BARD1 and tumour suppressors FOXP1, WASF1 and RB1 . Representing only a fraction of the vast African diaspora, this study raises considerations with respect to the contribution of kilo-to-mega-base rare variants to PCa pathogenicity and African associated disparity.
