    Evidence for Unified Assessment Criteria of HER2 IHC in Colorectal Carcinoma. (PubMed, Mod Pathol)
    Among 22 HER2-positive/heterogenous cases with successful ISH testing, 100% (22/22) demonstrated amplification via ISH. Because the classification of tumors as HER2-positive/heterogenous by IHC correlated very closely with ISH positivity, our results suggest that ISH is likely unnecessary for CRCs with 3+ HER2 overexpression in 10-49% of neoplastic cells.

    Detection of Novel Fusion Events in Gastric Carcinoma Involving the ARHGAP Gene Family (AMP 2024)
    Our study documents novel fusions in MSS gastric carcinoma involving the ARHGAP family. Patients with these tumors usually lack eligibility for targeted therapies, such as those directed against HER2 and involving immune checkpoint inhibition, and could ultimately benefit from new treatment avenues modulating RHOA activity as a result of ARHGAP fusions.

    Comprehensive characterization of the androgen receptor in male breast cancer (SABCS 2024)
    Our analysis suggests a strong association between AR expression and TP53 mutations, TMB-H, and PD-L1 positivity, immune cell infiltration, immune checkpoint and stem cell-related gene. Also, T cell inflamed and IFNy score were inversely related. Further exploration of specific alterations and immune-oncology markers associated with AR expression may help in clinical trial design for male patients with BC.

    Identifying Regulators of MHC Repression and therapeutic targets to overcome immune evasion in SCLC. (EORTC-NCI-AACR 2024)
    We provide novel insight into the mechanisms of SCLC immunotherapy resistance and MHC repression. We established the heterogeneity of MHC repression across SCLC tumors and identified networks and pathways that can be targeted to de-repress MHC-I in SCLC. Moreover, we identified the direct role of DNAPKCs as a therapeutic target that can augment the anti-tumor immune response of PD-L1 blockade by induction of MHC-I expression in SCLC.

    Androgen production, uptake, and conversion (APUC) genes define prostate cancer patients with distinct clinical outcomes. (PubMed, JCI Insight)
    The APUC-6 high/AR-low tumors represented a subgroup of patients with good clinical outcomes in contrast to the AR-high or neuroendocrine prostate cancers. Altogether, measuring the aggregate expression of APUC-6 genes in current genomic tests identifies PCs that are ligand- (rather than AR-) driven and require distinct therapeutic strategies.

    Impact of TLS status on outcomes in patients with high TMB or MSI-high status treated with immune checkpoint inhibitors (ESMO 2024)
    High TLS gene expression signatures, particularly in the highest quartile, are associated with favorable outcomes in patients with high TMB or MSI-High status treated with pembrolizumab. These findings suggest that TLS status could serve as a potent biomarker to stratify patients more likely to benefit from ICI therapy, advocating for its integration into routine clinical assessments prior to ICI treatment in these specific group of patients.

    Atlas of tertiary lymphoid structures in solid tumors: Genomic features and prediction of response to immunotherapy (ESMO 2024)
    We assessed gene signatures indicative of B cell infiltration/TLS presence (Messina et al., 2012; Goc et al., 2014; Cabrita et al., 2020; Meylan, et al., 2022), correlating these with clinical outcomes, including overall survival (OS) and time on treatment (TOT) for ICIs such as pembrolizumab, nivolumab, and ipilimumab. This large TLS atlas based on real-world data demonstrate that TLS gene is a robust biomarker for predicting responses to immunotherapy in solid tumors.

    Correlative Analysis of ATM, RB1, ERCC2, and FANCC Mutations and Pathologic Complete Response After Neoadjuvant Chemotherapy in Patients with Muscle-invasive Bladder Cancer: Results from the SWOG S1314 Trial. (PubMed, Eur Urol)
    P2; Using the CARIS 592 Gene Panel (Caris Life Sciences, Phoenix, AZ, USA), we analyzed 105 pre-NAC tumor specimens from a large multicenter trial (S1314) of either neoadjuvant gemcitabine and cisplatin (GC), or dose-dense methotrexate, vinblastine, Adriamycin, and cisplatin (DDMVAC). We conclude that this biomarker test, when combined with careful clinical assessment, can be used to allocate patients to careful bladder surveillance instead of surgery. This hypothesis has been tested in the RETAIN trial presented previously (NCT02710734).

    The impact of metformin on clinical outcomes of metastatic colorectal cancer with known molecular profile treated with cytotoxic chemotherapy or immune checkpoint inhibitor. (ASCO 2024)
    In this retrospective analysis of real-world clinical outcomes, patients receiving concomitant metformin and cytotoxic chemotherapy had improved clinical outcomes in MSS CRC compared to those not on concurrent metformin. However, the concurrent use of metformin with ICIs in MSI-H CRC did not show an impact on clinical outcomes given low sample size. These results add to the existing body of literature on the potential benefits of metformin in the context of MSS CRC and underscore the importance of a prospective controlled study of concurrent metformin use with systemic chemotherapy in metastatic CRC.

    Real-world impact of KRAS mutations on clinical outcomes in metastatic colorectal cancer treated with trifluridine-tipiracil in the USA. (ASCO 2024)
    To our knowledge, this is the largest primarily US-based cohort of mCRC treated with FTD-TPI to be reported. KRAS G12 mutation, but not KRAS G13 mutation, was associated with shorter rwOS and ToT compared to KRAS WT, despite enrichment of TP53 and BRAF mutations in the KRAS WT group. This finding is consistent with previously published analyses of large randomized prospective trials of FTD-TPI in mCRC and further support KRAS mutation status as a predictive biomarker in this setting.

    This association held for tumors treated with Immune Checkpoint Inhibitors (ICI) (9.6 m vs 4.6 m, HR=0.71 95% CI: 0.52-0.97, p=0.031), Gemcitabine/Nab-paclitaxel treated (15.3 m vs 8.1 m, HR=0.57 95% CI: 0.52-0.61, p<0.001) as well as mFOLFIRINOX treated tumors (20.3 m vs 12.0 m, HR=0.57 95% CI: 0.52-0.63, p<0.001). When comparing pancreatic LM to OM sites, our data reinforces the observation that OS is better in OM vs LM and response to ICI was better in OM vs. LM. Significant differences were observed in molecular landscape, TME and signatures that are predictive of immunotherapy response (TIS and IFG scores).

    RNA expression-based hypoxia score as a prognostic and predictive biomarker in hepatocellular carcinoma. (ASCO 2024)
    Yet, no significant difference in survival since start of treatment (SSOT) was observed in the patient subset that received Atezolizumab (Atezo) (-H: 210 D, -M: 355 D, -L: 386 D, p= 0.54). In HS-M tumors alone, SSOT was similar across investigated therapeutics (Atezo 322 D, Lenvatinib (Lenvat) 366.5 D, Sorafenib (Soraf) 289 D, p= 0.34)... In HCC, RNA expression-based HS is associated with TP53 mutations and an immunosuppressive microenvironment. HS-H tumors has worse OS that may be improved with Atezo, whereas HS-L tumors may respond better to Soraf. HS is a potential prognostic and predictive biomarker in HCC that deserves validation in orthogonal data sets and prospective studies.

    Unlocking therapeutic potential: IL-1β as a target in non-small cell lung cancer with oncogenic mutations—Prognostic and predictive insights. (ASCO 2024)
    The phase II CANTOS trial incidentally showed reduced lung cancer incidence and mortality with the IL-1β inhibitor canakinumab... Our study shows promising prognostic value of IL-1β expression in NSCLC, associating low expression with improved OS across NSCLC subtypes. IL-1β expression is closely linked to key driver mutations in NSCLC and may have predictive value for ICIs. The findings suggest the potential benefit of targeting IL-1β in high IL-1β expressing NSCLC with driver mutations.

    Characterization of necroptosis activators in colorectal cancer. (ASCO 2024)
    NA-H showed significantly improved OS in FOLFOX/FOLFIRI (F/F) (NA-L: 34.3 vs NA-H: 39.6 months [mo], P< 0.001; HR = 0.83, 95% CI 0.77 – 0.90) and those treated with IO (15.3 vs 22.4 mo, P = 0.018; HR = 0.77, 95% CI 0.62– 0.96) treated CRC patients... This is the largest molecular and clinical characterization of necroptotic genes in CRC. Our data shows that activation of the necroptosis pathway is associated with immune cell infiltration/pathway activation, PD-L1 expression, and improved OS on F/F and IO. This benefit is more pronounced in TP53-mutated CRC, suggesting possible novel therapeutic targets.

    The molecular landscape of PIWIL1 expression in colorectal adenocarcinoma (CRC). (ASCO 2024)
    PIWIL1-H CRC is associated with higher rates of dMMR/MSI-H, TMB-H and PD-L1+ as well as IO-related gene expression and signatures that are predictive of response to IO. These data suggest the PIWIL1-H subpopulation could potentially derive substantial benefit from PIWIL1-targeted immunotherapy which should be evaluated in clinical trials.

    Uncovering actionable genetic alterations and immune predictive biomarkers for anal squamous cell carcinomas in the era of immunotherapy: PD-L1 and beyond. (ASCO 2024)
    PD-L1 is expressed in over 50% of SCACs, while dMMR/MSI-H is rare. High PD-L1-expressing tumors have higher PIK3CAand CASP8 mutations and overexpress IO markers, are inflamed, and have prolonged treatment times with ICIs. This is the largest study to date reporting SCAC genomic profiles and identifies the utility of PD-L1 as a predictive biomarker of IO efficacy.

    Molecular and immunological characterization of androgen receptor expression in different breast cancer subtypes. (ASCO 2024)
    Post-doxorubicin survival was longer for patients with AR-H tumors; however, opposing trends were observed for patients with LumB (75.5 vs 56.3 m; p=.081) and HER2-enriched tumors (47.9 vs 65.2 m; p.071)... Findings from our updated analysis based on PAM50 designation suggest a strong association between AR and PIK3CA mutations across subtypes and suggest that distinct AR-associated alterations in the immune microenvironment require further study. Exploration of specific mutations and immune-oncology markers associated with AR-H may aid in molecularly selected clinical trial design for advanced BC patients.

    Kinome reprogramming as a therapeutic opportunity in ESR1 fusion driven breast cancer but not in gynecologic cancers. (ASCO 2024)
    We highlight that ESR1fusions can be reliably detected in patients with breast cancer, ovarian cancer, and endometrial cancers. ESR1 fusions lose the ligand binding domain and cannot be targeted using current estrogen modulators or degraders. We have discovered the upregulation of oncogenic kinase signaling in ESR1 fusion positive breast cancer, but not in gynecologic cancers.

    Increased B cell, M1 and M2 macrophage infiltrates, and increased prevalence of T-cell inflamed tumors in ANTXR1 H TME suggest that these patients with SCLC may respond preferentially to ICI. A Phase 1 trial incorporating SVV-01 along with ICI is underway. Prospective investigation of molecular associations and clinical outcomes related to ANTXR1 expression in SCLC is warranted.

    Clinical and molecular characterization of AXL in colorectal cancer: CALGB (Alliance)/SWOG 80405 and real-world data. (ASCO 2024)
    Data from the phase III CALGB/SWOG 80405 trial on 433 metastatic CRC (mCRC) patients treated with bevacizumab (Bev, n = 226) or cetuximab (Cet, n = 207) in combination with first-line chemotherapy were also evaluated...AXL-H demonstrated worse OS in FOLFOX/FOLFIRI treated CRC (H: 35.7 vs L: 38.7 months [mo], P = .003; HR 1.08, 95% CI [1.03-1.14])... Our results indicate increased AXL expression is associated with immune cell infiltration, EMT, and inflammatory signaling. AXL-H confers worse OS/PFS on first-line chemotherapy, with a more pronounced effect in KRASwt CRC. This data supports evaluation of AXL as a prognostic marker and potential therapeutic target in CRC.

    Molecular and immune characterization of squamous cell ovarian cancers for identification of therapeutic targets. (ASCO 2024)
    OSCC had worse post-Carboplatin survival (19.6 mo) compared to EOC (71.6 mo, p<0.01) and CCOC (46.9 mo, p<0.01), similar post-Carbo survival to TP53-mt CSCC (22.5 mo; p=0.80) but improved post-Carbo survival compared to TP53-mt VSCC (9.05 mo; p=0.01)... The molecular and transcriptomic profile of OSCC is distinct from EOC, CCOC, and BT but similar to CSCC and VSCC. OSCC demonstrated a more immune hot phenotype. Further studies are needed to investigate the potential use of immunotherapy in OSCC.

    Characterization of ESR1 mutations in endometrial and ovarian cancers. (ASCO 2024)
    ESR1mt were more common in EC and were enriched in the endometrioid subtype, and in general associated with increased molecular alterations but a more cold immune microenvironment. Hotspot mutations known to confer endocrine resistance were most common and enrichment was observed in cases previously exposed to AIs, suggesting this may be a mechanism of resistance to endocrine therapy for some gynecologic malignancies.

    This is the largest combined genomic, transcriptomic and survival outcomes analysis of PSMA (FOLH1) expression in PC. In PC, greater FOLH1 mRNA expression was associated with higher AR signaling scores and AR-V7 expression, and fewer mutations in the Wnt and PI3K pathways. FOLH1-high pts showed greater T cell inflammation and PD-L1 expression, and lower NEPC signaling.
