Impact of CCND1 amplification on the prognosis of hormone receptor-positive, HER2-negative breast cancer patients-correlation of clinical and pathological markers. (PubMed, Breast Cancer Res Treat)

CCND1 amplification is a recurring event in breast cancer, occurring most frequently in luminal B-like and HER2-amplified subtypes. A trend toward less favorable outcomes was observed among CCND1-amplified HR-positive, HER2-negative tumors.

Point mutations (PM), gene amplifications (GA) and variants of unknown significance (VUS) detected by next-generation sequencing (NGS) in a real-world sample of metastatic breast cancer (MBC) (SABCS 2024)

NGS of real-world patients reveals a broad spectrum of genomic abnormalities in MBC. TP53 and PIK3CA associate with TNBC and luminal MBC, respectively. Mutations in tumor suppressors are mostly distinct since there are many ways to induce loss-of-function.

Thus, the 11q13 amplicon drives SCC through at least three independent genetic elements and suggests therapeutic targets for this morbid and lethal disease. Implications: This work demonstrates novel mechanisms and ways to target these mechanisms underlying the most common amplification in squamous cell carcinoma, one of the most prevalent and deadly forms of human cancer.

Results of Comprehensive Genomic Profiling of Metastatic Breast Cancer Patients at a Single Institute in Japan (SABCS 2023)

Three HER2-negative patients were prescribed anti-HER2 therapy for ERBB2 amplification, one patient was prescribed entrectinib for NTRK fusion, and three patients participated in clinical trial for ERBB2 mutation and FGFR1 rearrangement. If ESCAT ranking beyond I/II and recommended therapy from FoundationOne report (e.g Abemaciclib for CCND1 amplification, Everolimus for PTEN loss)are added, 64 pts (60.1%) were considered these treatments, and 19 pts (18.1%) actually received these treatment...Low accessibility of ESCAT ranking I/II MT may be because, in Japan, CGP testing is available only for patients who have completed or are expected to complete standard therapy. Early use of CGP testing and an increase in clinical trials will be desirable in Japan.

Baseline genomic alterations and the activity of lasofoxifene (LAS) plus abemaciclib (Abema) in patients with ER+/HER2- metastatic breast cancer (mBC): the ELAINE 2 study (SABCS 2023)

Of the 29 patients (median age 60 yrs) enrolled, mutations in ESR1 were identified in 26 by Guardant360; all these 26 patients had received prior CDK4/6i, 21 (81%) prior fulvestrant, and 12 (46%) prior chemotherapy for mBC. Using Guardant360 ctDNA profiling from patients in ELAINE 2, we demonstrate that other baseline genomic alterations are frequently detected concurrently with mESR1 in the endocrine resistant setting, but without apparent compromise on the efficacy of LAS plus Abema. These results should be interpreted with caution considering the small numbers of patients and the exploratory nature of the analysis. The ELAINE 2 study suggests the potential of LAS plus Abema for treating ESR1-mutated, ER+/HER2- mBC in the post-CDK4/6i setting.

Somatic mutations of a multigene panel in Chinese HER2-positive patients undergoing neoadjuvant therapy and impact on prognosis based on TP53 status:a single-institution retrospective cohort (SABCS 2023)

Furthermore, TP53 mutations had significant prognostic importance in HER2-positive BC patients with HR-negative (HR=3.712, P=0.0266), pCR (HR=6.253, P=0.0268) and who received trastuzumab-only targeted therapy (HR=4.145, P=0.0105). Regard to diverse hormone receptor status or neoadjuvant efficacy, the genetic mutation maps of Chinese HER2+ patients receiving NAT are disparate. Our study found that TP53 mutations have significant prognostic value in patients with NAT for HER2-positive BC and patients benefit differently depending on HR status, neoadjuvant regimens and response.

Examining Rare Genitourinary Cancers for Genetic Biomarkers to Explore Potential Targeted Therapy Options (AMP 2023)

Data from this small cohort of rare tumors suggest that SCNC and SqCB exhibit common driver/targetable mutations seen in other hematologic and solid tumors that might represent new therapeutic targets in these rare tumor types. Our identification of mutations unique to different histologies in the same tumor argues for independent sequencing of different histologies to broaden the search for targetable mutations.

Aumolertinib Plus Anlotinib in Advanced NSCLC with Brain Metastasis: A Single-arm, Phase II Study (IASLC-WCLC 2023)

In addition, EGFR-TKIs combined with bevacizumab can further improve the efficacy, as reported in study JO25567 and NEJ026. Aumolertinib plus anlotinib showed preliminary efficacy as first-line therapy in EGFR-mutant NSCLC patients with brain metastases. The initial subgroup results may demonstrated superior activity of aumolertinib plus anlotinib in patients with multiple intracranial metastases or EGFR 19Del positive. And although with comutations, NSCLC patients with brain metastasis can still benefit from aumolertinib plus anlotinib.

ERα-associated translocations underlie oncogene amplifications in breast cancer. (PubMed, Nature)

A pan-cancer analysis reveals tissue-specific biases in mechanisms initiating focal amplifications, with the breakage-fusion-bridge cycle prevalent in some and the translocation-bridge amplification in others, probably owing to the different timing of DNA break repair. Our results identify a common mode of oncogene amplification and propose oestrogen as its mechanistic origin in breast cancer.

Clinical Application of Liquid Biopsy across Pan- Cancer: 4baseCare's Experience Using TarGT Indiegene- Liquid Biopsy NGS Panel (AMP Europe 2023)

The MRD estimation was evident in a breast cancer patient with ERBB2 amplification detected while the patient was on maintenance trastuzumab... This pan- cancer pilot study using the TarGT Indiegene Liquid Biopsy Panel supports the hypothesis that molecular information obtained from liquid biopsy can play a significant role in clinical decision-making, in addition to tissue mutation profiling. The results of this study demonstrate the potential clinical utility of this liquid biopsy panel in identifying actionable genomic alterations in patients with advanced stage cancer. These findings suggest that liquid biopsy has the potential to complement tissue biopsy and provide important molecular information to inform personalized treatment decisions for patients with cancer.

Molecular Landscape of Small-Cell and Large-Cell Neuroendocrine Carcinomas of the Gastroenteropancreatic System (Selected for Oral Presentation, O-01-02) (AMP Europe 2023)

The findings provide insight into the pathogenesis of GEP- NECs and highlight limited similarities to SCLC. Despite the paucity of data about the molecular drivers associated with GEP-NECs, a high fraction of targetable alterations (46% in our cohort) indicates a high potential for better-personalized treatments.

Integrated genomic analysis refines molecular classifications of hepatocellular carcinoma based on a large-scale cohort of 529 samples (EACR 2023)

Another subgroup was defined by both CTNNB1ex3 and TP53 mutations, which presented mixed features of CTNNB1ex3 HCC and TP53-mut HCC. In clinicopathological and genomic level, this subgroup presented the characteristics of TP53-mut HCCs with an enrichment of HBV infection, higher Edmonson III-IV grade and CCND1-FGF19 amplification, more copy-number events and high proportion of whole-genome duplication and was associated with poor prognosis, while in the transcriptomic level, CTNNB1ex3; TP53 HCC clustered with CTNNB1ex3 HCCs.ConclusionWe refined the molecular classifications of HCC, which may be useful for therapeutic strategy.

Prognostic Values of Gene Copy Number Alterations in Prostate Cancer. (PubMed, Genes (Basel))

The best model of 7/52 genetic CNAs, which included the SPOP alteration, SPP1 alteration, CCND1 amplification, PTEN deletion, CDKN1B deletion, PARP8 deletion, and NKX3.1 deletion, stratified the PCa cases into a localised and advanced disease with an accuracy of 70.0%, sensitivity of 85.4%, specificity of 44.9%, positive predictive value of 71.67%, and negative predictive value of 65.35%. This study validated prognostic gene level CNAs identified in previous studies, as well as identified new genetic markers with CNAs that could potentially impact risk stratification in PCa.

Identification of BRAF, CCND1, and MYC mutations in a patient with multiple primary malignant tumors: a case report and review of the literature. (PubMed, World J Surg Oncol)

This is the first reported case of a patient with the co-existence of MM, PTC and ccRCC undergoing chemotherapy with a favorable prognosis. Herein, we suggest that such a combination may be non-random, as for mutation of BRAF might account for the co-occurrence of PTC and MM, while mutations of CCND1 and MYC cause the coexistence of MM and ccRCC. This finding may provide valuable guidance on the diagnosis and treatment of such disease, as well as the prevention of developing a second or third tumor for patients with a single primary.
