    Response to Carboplatin and Paclitaxel in the treatment of hereditary breast ovarian cancer syndrome (HBOC): a case report. (PubMed, J Pak Med Assoc)
    This dynamic treatment not only led to nearly complete remission of high-grade ovarian serous cancer but also triggered regression in grade-2 invasive ductal breast cancer after just a few rounds of chemotherapy. Consequently, what started as palliative care evolved into a curative triumph.

    Identifying Novel Germline Mutations and Copy Number Variations in Patients With SCLC. (PubMed, JTO Clin Res Rep)
    Patients with SCLC with the seven pathogenic alterations were observed to have a numerically longer overall survival (hazard ratio = 0.50) and progression-free survival (hazard ratio = 0.45) though not statistically significant compared with the remaining cohort. Our study identifies novel germline alterations, including a CNV, and provides additional evidence that germline factors could be important contributing factors to the development of SCLC.

    Efficacy of olaparib (O) plus abiraterone (A) versus placebo (P) plus A in patients (pts) with metastatic castration-resistant prostate cancer (mCRPC) with single homologous recombination repair gene mutations (HRRm) in the PROpel trial. (ASCO-GU 2024)
    BRCA2, ATM and CDK12 were the most prevalent single gene mutations and clinical benefit was observed with O + A. Other single gene mutations were rare, limiting interpretation. The greatest treatment benefit was observed in pts with BRCA mutations. Clinical trial information: NCT03732820.NR, not reached; BRIP1, RAD51B, RAD51D n=1; CHEK1, RAD51C n=0.

    Real-world homologous recombination repair mutation (HRRm) testing patterns in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with olaparib in the United States. (ASCO-GU 2024)
    Pts with confirmed mCRPC diagnosis, age ≥21 years, treated with olaparib monotherapy after exposure to abiraterone or enzalutamide, and with positive HRRm status were included. This real-world analysis highlights the need for earlier HRRm testing in pts with mCRPC to allow for optimal timing of novel treatment options that have shown efficacy in a biomarker-selected population. Most pts in this study were tested and diagnosed with HRRm many months after mCRPC diagnosis, at which point they had high levels of bone metastasis, multiple sites of distant metastases, and opioid use at the initiation of olaparib treatment. HRR testing in pts before or at the time of mCRPC would allow for olaparib therapy earlier in the disease course.

    Whole Exome Sequencing reveals clinically important pathogenic mutations in DNA repair genes across lung cancer patients. (PubMed, Am J Cancer Res)
    The observed pathogenic mutations in BRCA1, BRCA2, ERCC6, CHEK1, MUTYH, and RAD51D, coupled with their down-regulation and hypermethylation, suggest a potential convergence of genetic and epigenetic factors driving genomic instability in lung cancer cells. These findings contribute to our understanding of lung cancer susceptibility and highlight potential avenues for targeted therapeutic interventions in Pakistani lung cancer patients.

    The role of DNA repair genes mutational status in prostate cancer treatment with androgen signaling blockade (EMUC 2023)
    Probably, the data obtained on the worst efficacy of enzalutamide after docetaxel in patients with mutations in  HRR genes can be attributed to the biological features of the influence of therapy methods on the course of the disease. In clinical practice, it is advisable to take into account the fact of the influence of previous treatment on the effectiveness of antiandrogenic therapy in choosing the sequence of treatment methods.

    Preliminary functional experiments in HRP (HR proficient, n=5) and HRD (n=4) PDX and organoids (n=3 and n=3 for HRD and HRP respectively) indicate that HRD tumors present low RAD51 foci count (p=0.03 after damage induction) and favorable response to Olaparib and CDDP. Conclusions These data suggest that homologous recombination may be deficient in a substantial proportion of early-stage NSCLC patients, supporting the potential use of PARPi in HRD patients in the adjuvant or maintenance setting.

    LP-184, a Tumor Site Activated Small Molecule Acylfulvene, Is Effective Preclinically in Subsets of Lung Cancer (IASLC-WCLC 2023)
    H460 KEAP1/STK11 mutant cell line derived xenograft model was used to demonstrate the anti-tumor activity of LP-184. LP-184 displayed strong nanomolar potency in 7 day ex vivo treatment in a panel of patient derived lung cancer models carrying ATM, BRCA1 or CHEK1 mutations with IC50s in the range of 30 - 200 nM, which turned out to be 12-350 times superior to that of Olaparib across the same models. LP-184 is highly effective in selected molecular subsets of lung cancer in proof-of-concept ex vivo and in vivo studies, supporting its clinical development in small cell and non-small cell lung cancers. IND-enabling repeat dose GLP toxicology studies of LP-184 show it to be well tolerated in rats and dogs. A first-in-human dose escalation Phase 1A trial with LP-184 is expected to enroll all advanced solid tumors including lung cancers.

    In conclusion, we present a mutational landscape of actionable genes in CRC for the SA population in patients without a familial history of CRC. Additionally, we address the clinical relevance of low variant allele frequency variants. A comprehensive analysis of population-specific molecular markers for CRC can provide insights into the disease progression, with an aim of optimizing individualized therapeutic options and treatment regimens in the management of CRC in the SA population.

    LP-184, an acylfulvene class small molecule therapeutic, is synthetically lethal in DNA damage repair deficient cancers (AACR 2023)
    LP-184 treatment resulted in complete tumor regression (107-141% TGI) in 10/10 HR deficient triple negative breast cancer PDX models of which 7/10 were resistant Olaparib/ Niraparib and to Doxorubicin/ Cyclophosphamide. Unlike PARPi, LP-184 has striking activity in both NERD as well as HRD cancers. These strong data have prompted the development of a soon to be launched clinical trial to translate the broad preclinical anticancer activity of LP-184 in solid tumors with HR/NER pathway defects, such as pancreatic, prostate, ovarian and breast cancers.

    Pan-cancer proteogenomics expands the landscape of therapeutic targets (AACR 2023)
    Based on tumor proteogenomic data and cell line CRISPR-Cas9 screen data, we identified synthetic lethality for difficult to target tumor suppressor losses, revealing TP53 mutations as a candidate biomarker to select breast cancer patients for CHEK1 inhibition, and endometrial cancer patients for treatment with doxorubicin... We generate a comprehensive resource of protein and peptide targets that covers multiple therapeutic modalities. This unique resource will pave the way for repurposing of currently available drugs and developing new drugs for cancer treatment.

    Concurrent loss of MLH1, PMS2 and MSH6 immunoexpression in gastrointestinal cancer indicating a widespread dysregulation in DNA reparation processes (ECP 2022)
    Our study suggests that the simultaneous loss of MLH1, PMS2 and MSH6 immunoexpression among diferent gastrointesti-nal cancers is associated with and potentially even based on more widespread alterations in DNA repair processes. Next-generation sequencing could reveal further mutations in additional DNA repair-related genes in the present cases. With the advent of drugs targeting DNA repair in clinical practice, especially PARP-inhibitors, and their potential indication extension for mutations other than BRCA1/2 such as PALB2 our results are of immediate clinical signifcance.

    The Prevalence of CHEK 1 and CHEK 2 mutations in prostate cancer in Jordan population: a retrospective cohort study (ECP 2022)
    We found, and in line with previous studies, lack of association between CHEK1 mutations and PCa development. The presence of 1.4% of mutation in CHEK2 in our results supported the possible role of genetic variants in this gene and the develop-ment of PCa. Further studies are needed with larger cohorts to shed more light on these findings and to reveal the genetic predisposi-tion of the CHEK2 gene in the development of PCa in Jordan and perform screening of more exons.

    Genomic and immunologic profiles of concurrent RB1 and CDKN1A/p21(WAF1) truncating mutations (RW+) in bladder cancer. (ASCO 2022)
    Truncating WAF1 mutations are associated with sensitivity to cisplatin and are associated with truncating Rb mutations in bladder cancer (RW+)... Concurrent truncating mutation in RB1 and WAF1 (RW+) bladder carcinomas have fewer p53, ARID1A, and PIK3CA mutations but are enriched for E2F targets, G2/M checkpoint genes, FANCC/A, CHEK1, WEE1, CDC25A/C, PALB2 and BRCA1/2 and have a distinct immunological profile. The findings suggest therapeutic strategies for RW+ bladder cancers including Chk1/Wee1, PARP inhibitors, -/+ immunotherapy that may impact on clinical outcomes.

    Analysis of the role of PI3K-AKT and DNA damage repair (DDR) genomic biomarkers as predictors of clinical outcomes in non-metastatic castration-resistant prostate cancer (nmCRPC). (ASCO-GU 2022)
    Of the 37 patients included, 30 (82%) received apalutamide, 5 (13%) received darolutamide, and 2 (6%) received enzalutamide...Of those who had subsequent treatment, 1 received enzalutamide and 5 received abiraterone... This final analysis demonstrates that nmCRPC with PI3K and DDR signalling pathway mutations have poor clinical outcomes when treated with ARAT, likely secondary to decreased reliance on the androgen receptor signalling pathway. These results highlight the potential value of exploring targeted therapies, such as PARP or AKT inhibitors in patients with these mutations.
