Negative Hyperselection of Patients with HER2+ and RAS Wild-Type Metastatic Colorectal Cancer Receiving Dual HER2 Blockade: the PRESSING-HER2 Study. Clin Cancer Res 2024; 30:436-443. [PMID: 37610454 PMCID: PMC10792357 DOI: 10.1158/1078-0432.ccr-23-1379] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/13/2023] [Accepted: 08/21/2023] [Indexed: 08/24/2023]
Abstract
PURPOSE To demonstrate the negative prognostic impact of a panel of genomic alterations (PRESSING-HER2 panel) and lack of HER2 amplification by next-generation sequencing (NGS) in patients with HER2+, RAS wild-type metastatic colorectal cancer receiving dual HER2 blockade. EXPERIMENTAL DESIGN The PRESSING-HER2 panel of HER2 mutations/rearrangements and RTK/MAPK mutations/amplifications was assessed by NGS. HER2 amplification was confirmed by NGS if copy-number variation (CNV) was ≥ 6. With a case-control design, hypothesizing 30% and 5% PRESSING-HER2 positivity in resistant [progression-free survival (PFS) <4 months and no RECIST response] versus sensitive cohorts, respectively, 35 patients were needed per group. RESULTS PRESSING-HER2 alterations included HER2 mutations/rearrangements, EGFR amplification, and BRAF mutations and had a prevalence of 27% (9/33) and 3% (1/35) in resistant versus sensitive patients (P = 0.005) and 63% predictive accuracy. Overall, HER2 nonamplified status by NGS had 10% prevalence. Median PFS and overall survival (OS) were worse in PRESSING-HER2+ versus negative (2.2 vs. 5.3 months, P < 0.001; 5.4 vs. 14.9 months, P = 0.001) and in HER2 nonamplified versus amplified (1.6 vs. 5.2 months, P < 0.001; 7.4 vs. 12.4 months, P = 0.157). These results were confirmed in multivariable analyses [PRESSING-HER2 positivity: PFS HR = 3.06, 95% confidence interval (CI), 1.40-6.69, P = 0.005; OS HR = 2.93, 95% CI, 1.32-6.48, P = 0.007]. Combining PRESSING-HER2 and HER2 CNV increased the predictive accuracy to 75%. CONCLUSIONS PRESSING-HER2 panel and HER2 nonamplified status by NGS warrant validation as potential predictive markers in this setting. See related commentary by Raghav et al., p. 260.

Prognostic and predictive biomarkers for anti-EGFR monoclonal antibody therapy in RAS wild-type metastatic colorectal cancer: a systematic review and meta-analysis. BMC Cancer 2023; 23:1117. [PMID: 37974093 PMCID: PMC10655341 DOI: 10.1186/s12885-023-11600-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Accepted: 11/01/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND RAS mutations affect prognosis in patients with metastatic colorectal cancer (mCRC) and have been identified as strong negative predictive markers for anti-epidermal growth factor receptor monoclonal antibody (anti-EGFR mAb) therapy, but many tumors containing wild-type RAS genes still do not respond to these therapies. Some additional biomarkers may have prognostic or predictive roles, but conclusions remain controversial. METHODS We performed a meta-analysis and systematic review of randomized controlled trials comparing anti-EGFR mAb therapy with alternative therapy that investigated the prognostic and predictive impact of additional biomarkers in RAS wild-type (wt) mCRC patients. Hazard ratios (HRs) and 95% confidence intervals (CIs) for progression-free survival (PFS) and overall survival (OS) and odds ratios (ORs) for objective response rate (ORR) were calculated. The prognostic value of biomarkers was investigated by separately pooling HR and OR for different treatment groups in an individual study. The predictive value was assessed by pooling study interactions between treatment effects and biomarker subgroups. RESULTS Thirty publications reporting on eighteen trials were selected, including a total of 13,507 patients. In prognostic analysis, BRAF mutations were associated with poorer PFS [HRs = 3.76 (2.47-5.73) and 2.69 (1.82-3.98)] and OS [HRs = 2.66 (1.95-3.65) and 2.45 (1.55-3.88)] in both the experimental and control arms; low miR-31-3p expression appeared to have longer PFS and OS. In terms of predictive effect, a lack of response to anti-EGFR therapy was observed in patients with BRAF mutant tumors (Pinteraction < 0.01 for PFS). Patients with tumors with any mutation in the KRAS/NRAS/BRAF/PIK3CA gene also showed similar results compared with all wild-type tumors (Pinteraction for PFS, OS, and ORR were < 0.01, < 0.01 and 0.01, respectively). While low miR-31-3p expression could predict PFS (Pinteraction = 0.01) and OS (Pinteraction = 0.04) benefit. The prognostic and predictive value regarding PIK3CA mutations, PTEN mutations or deletions, EGFR, EREG/AREG, HER2, HER3, and HER4 expression remains uncertain. CONCLUSIONS In RAS wt mCRC patients receiving EGFR-targeted therapy, BRAF mutation is a powerful prognostic and therapy-predictive biomarker, with no effect found for PIK3CA mutation, PTEN mutation or deletion, but the combined biomarker KRAS/NRAS/BRAF/PIK3CA mutations predict resistance to anti-EGFR therapy. Low miR-31-3p expression may have positive prognostic and therapy predictive effects. Evidence on the prognostic and predictive roles of EGFR and its ligands, and HER2/3/4 is insufficient.

CRISPR/Cas12a and primer-assisted rolling circle amplification integrated ultra-sensitive dual-signal sensing platform for EGFR 19 detection. Anal Chim Acta 2023; 1279:341755.

Abstract
Herein, we integrated CRISPR/Cas12a with primer-assisted rolling circle amplification (PARCA) to specifically detect EGFR 19 from the genome. We fused the method into fluorescent and electrochemical detection systems forming a stable and sensitive dual-signal sensing platform. The fluorescent detection system stably detected EGFR 19 in a linear range from 500 fM to 10 nM with an ultra-low background signal. The electrochemical detection system possessed a detection limit as low as 42 aM due to the introduction of nanomaterial UIO-66-NH2. The dual-signal sensing platform showed superior performance in complex serum samples and real cell genomes and provided a flexible and dynamic approach for the ultra-sensitive detection of EGFR 19.

Abstract
Overexpression of the EGFR ligands amphiregulin (AREG)/epiregulin (EREG) may be a surrogate of EGFR dependency regardless of sidedness in metastatic colorectal cancer. High AREG/EREG may be coupled with negative hyper-selection (i.e., lack of genomic drivers of primary resistance beyond RAS and BRAF) to identify patients with right-sided tumors and potential sensitivity to EGFR blockade. See related article by Williams et al., p. 4153.

Abstract
Liquid biopsies can be a rapid, cost-effective and non-invasive alternative to tumour biopsies for detecting genetic mutations in somatic tumours. Genetic profiling of liquid biopsies can also be used to identify novel antigens for targeted therapy, provide updated information on disease prognosis and evaluate treatment efficacy. In this study, we aimed to examine mutations that could be identified in liquid biopsy and their distribution in a small study cohort. We studied the genomic profiles of 99 blood samples from 85 patients with 21 different types of cancer using two commercially available liquid biopsy tests. The mean circulating free DNA (cfDNA) concentration was 162.7 ± 352.3 nanograms per 20 millilitres. Amongst cfDNA, the circulating tumour DNA (ctDNA) percentage ranged from 0.006% to 90.6%. With the exception of samples with gene amplification and high microsatellite instability, the number of mutations in each sample varied from zero to 21, with an average of 5.6 mutations in each patient. Amongst these mutations, nonsynonymous mutations were the most frequently observed type of mutation (90% of the sample, with an average frequency of 3.6 mutations per patient). Mutations were observed in 76 different genes. TP53 mutations constituted more than 16% of the detectable mutations, especially in non-small cell lung cancer. All the tumour types, except the ovary, kidney and apocrine gland tumours, harboured at least one type of TP53 mutation. KRAS (mainly in pancreatic cancer) and PIK3CA (mostly in breast cancer) mutations, were responsible for an additional 10% of the mutations in the studied samples. The tumour mutations were specific to each patient, as approximately 94.7% of the mutations were so unique that there was almost no duplication amongst the patients. These findings indicate that liquid biopsy can detect specific molecular changes of tumour, which is useful for precision oncology and personalized cancer treatment.

Abstract
OBJECTIVES Molecular analysis of tumor tissues has been extensively analyzed in germ cell tumors. However, genetic analysis of plasma circulating tumor DNA has been limited. Our objective was to analyze genetic alterations in circulating tumor DNA as well as its impact on prognosis in patients with chemo-refractory germ cell tumors. METHODS We included 13 patients with chemo-refractory germ cell tumors who relapsed after second-line or higher previous chemotherapy and performed targeted sequencing of plasma cell-free DNA using an AVENIO Expanded kit. RESULTS Tumor-specific genetic alterations were identified in all patients. The most frequently mutated gene was TP53 (53.4%), followed by PTEN (23.1%), GNAS (15.4%) and MTOR (15.4%). Moreover, EGFR amplification (38.5%) and MET amplification (15.4%) were also identified. We defined two or more single nucleotide variants detected in plasma cell-free DNA as circulating tumor DNA-positive. Kaplan-Meier analysis revealed that overall survival was significantly shorter in circulating tumor DNA-positive patients than circulating tumor DNA negative-patients (median overall survival 3.13 vs. 8.73 months; p = 0.042). CONCLUSION Analysis of plasma circulating tumor DNA could detect genetic alterations in patients with chemo-refractory GCT. Moreover, detectable circulating tumor DNA in plasma was associated with poor prognosis in those patients. These results suggest that liquid biopsy using analysis of plasma circulating tumor DNA may be clinically useful for germ cell tumor patients.

Abstract
Colorectal cancer (CRC) is the third most common cancer in the world. Currently, chemotherapy and radiotherapy used to treat CRC exhibit many side effects, hence, it is an urgent need to design effective therapies to prevent and treat CRC. Lactic acid bacteria (LAB) can regulate gut microbiota, intestinal immunity, and intestinal mechanical barrier, which is becoming a hot product for the prevention and treatment of CRC, whereas comprehensive reviews of their anti-CRC mechanisms are limited. This review systematically reveals the latest incidence, mortality, risk factors, and molecular mechanisms of CRC, then summarizes the roles of probiotics in alleviating CRC in animal and clinical studies and critically reviews the possible mechanisms by which these interventions exert their activities. It then shows the limitations in mechanisms and clinical studies, and the suggestions for future research are also put forward, which will play an important role in guiding and promoting the basic and clinical research of remising CRC by LAB and the development of LAB products.

Abstract
Anti-EGFR targeting is one of the key strategies in the treatment of metastatic colorectal cancer (mCRC). For almost two decades oncologists have struggled to implement EGFR antibodies in the mCRC continuum of care. Both sidedness and RAS mutational status rank high among the predictive factors for the clinical efficacy of EGFR inhibitors. A prospective phase III trial has recently confirmed that anti-EGFR targeting confers an overall survival benefit only in left sided RAS-wildtype tumors when given in first line. It is a matter of discussion if more clinical benefit can be reached by considering putative primary resistance mechanisms (e.g., HER2, BRAF, PIK3CA, etc.) at this early stage of treatment. The value of this procedure in daily routine clinical utility has not yet been clearly delineated. Re-exposure to EGFR antibodies becomes increasingly crucial in the disease journey of mCRC. Yet re- induction or re-challenge strategies have been problematic as they relied on mathematical models that described the timely decay of EGFR antibody resistant clones. The advent of liquid biopsy and the implementation of more accurate next-generation sequencing (NGS) based high throughput methods allows for tracing of EGFR resistant clones in real time. These displays the spatiotemporal heterogeneity of metastatic disease compared to the former standard radiographic assessment and re-biopsy. These techniques may move EGFR inhibition in mCRC into the area of precision medicine in order to apply EGFR antibodies with the increase or decrease of EGFR resistant clones. This review critically discusses established concepts of tackling the EGFR pathway in mCRC and provides insight into the growing field of liquid biopsy guided personalized approaches of EGFR inhibition in mCRC.

Abstract
The systemic therapy management of metastatic colorectal cancer (mCRC) has evolved from primarily cytotoxic chemotherapies to now include targeted agents given alone or in combination with chemotherapy, and immune checkpoint inhibitors. A better understanding of the pathogenesis and molecular drivers of colorectal cancer not only aided the development of novel targeted therapies but led to the discovery of tumor mutations which act as predictive biomarkers for therapeutic response. Mutational status of the KRAS gene became the first genomic biomarker to be established as part of standard of care molecular testing, where KRAS mutations within exons 2, 3, and 4 predict a lack of response to anti- epidermal growth factor receptor therapies. Since then, several other biomarkers have become relevant to inform mCRC treatment; however, there are no published Canadian guidelines which reflect the current standards for biomarker testing. This guideline was developed by a pan-Canadian advisory group to provide contemporary, evidence-based recommendations on the minimum acceptable standards for biomarker testing in mCRC, and to describe additional biomarkers for consideration.

Abstract
Several uncommon genomic alterations beyond RAS and BRAFV600E mutations drive primary resistance to anti–epidermal growth factor receptors (EGFRs) in metastatic colorectal cancer (mCRC). Our PRESSING panel (including PIK3CA exon 20/AKT1/PTEN mutations, ERBB2/MET amplifications, gene fusions, and microsatellite instability-high status) represented a paradigm of negative hyperselection with more precise tailoring of EGFR blockade. However, a modest proportion of hyperselected mCRC has intrinsic resistance potentially driven by even rarer genomic alterations. Beyond RAS/BRAF: rarer alterations drive negative ultraselection for anti-EGFR therapy in mCRC

Variant allele frequency in baseline circulating tumour DNA to measure tumour burden and to stratify outcomes in patients with RAS wild-type metastatic colorectal cancer: a translational objective of the Valentino study. Br J Cancer 2022; 126:449-455.

Abstract
INTRODUCTION In patients with metastatic colorectal cancer (mCRC), baseline circulating tumour DNA (ctDNA) variant allele fraction (VAF) might serve as a surrogate of disease burden and should be evaluated in comparison with CEA and RECIST-defined sum of target lesions. METHODS In this pre-planned analysis of the VALENTINO trial, we included patients with RAS wild-type mCRC receiving upfront FOLFOX/panitumumab with available baseline liquid biopsy. CtDNA was analysed by means of a 14-gene NGS panel. For each patient, the gene with the highest VAF in ctDNA was selected. RESULTS The final cohort included 135 patients. The median VAF was 12.6% (IQR: 2.0-45.2%). Higher VAF was observed in patients with liver metastases and with synchronous metastases presentation. Patients with high VAF had poorer median OS compared to those with low VAF (21.8 vs 36.5 months; HR: 1.82, 95%CI: 1.20-2.76; p = 0.005). VAF outperformed baseline CEA and target lesion diameter in the prognostic stratification and remained significantly correlated with OS (p = 0.003) in a multivariate model. VAF was not significantly correlated with dimensional response and PFS. CONCLUSION CtDNA measured by VAF is prognostic in patients with RAS wild-type mCRC. Response and PFS after an anti-EGFR-based first-line strategy are independent from initial tumour burden.
