The Recurrent E-Cadherin (CDH1) Mutation c.760G>A Causes Orofacial Clefts but Does Not Predispose to Hereditary Cancer. (PubMed, Genes (Basel))

This review of 27 mutation carriers, including 3 who were 68, 70, and 77 years of age, indicates that c.760G>A does not confer an increased risk for HDGC. The relevance of differentiating craniofacial from cancer phenotypes in mutation carriers is substantial for precision medicine and for counseling families.

Development of a streamlined NGS-based TCGA classification scheme for gastric cancer and its implications for personalized therapy. (PubMed, J Gastrointest Oncol)

In the Korean cohort, ICIs were most effective in MSI and EBV cases, showing disease control rates of 100%, compared to 62.9% in GS and 12.5% in CIN subtypes. The NGS method successfully maps the mutational landscape of GC, providing a practical TCGA classification surrogate to optimize patient-specific treatment strategies.

Tumor genomics in young patients with metastatic breast cancer (SABCS 2024)

In EMBRACE, differences in mutational frequency of several genes were observed by age at MBC diagnosis among patients with recurrent MBC, most notably for HR+/HER2- patients. Lower OS among younger recurrent MBC patients may be driven by these differences, particularly by high frequency of TP53 mutations in this age group. Further investigation of these genes is warranted to elucidate pathways leading to metastasis and to improve survival for young MBC patients.

Structural Variants Affecting CDH1 in Breast Invasive Lobular Carcinoma (SABCS 2024)

We demonstrate that CDH1 affecting SVs act as drivers of a subset of ILCs. Most of these SVs result in loss of E-cadherin protein expression and a lobular phenotype, akin to CDH1 mutations. ILCs harboring CDH1 SVs were enriched for aggressive histologic features and display a repertoire of genetic alterations resembling that of ILCs with CDH1 mutations.

Prevalence of PIK3CA/AKT1/PTEN and other genomic alterations in primary and recurrent tumor tissue: exploratory analysis from the Phase 3 CAPItello-291 clinical trial (SABCS 2024)

Background Based on the positive results from the CAPItello-291 trial, capivasertib plus fulvestrant is a treatment option for adult patients with HR+/HER2− locally advanced or metastatic breast cancer who have progressed on an endocrine-based regimen and whose tumors harbor one or more alterations in PIK3CA, AKT1, or PTEN. Consistent with the literature, recurrent tissues were enriched for ESR1, BRCA2, GATA3, CDKN2A, and SMAD4 alterations, indicating a potential role for these gene alterations in driving disease recurrence. The PIK3CA/AKT1/PTEN-altered cohort was enriched for CDH1 mutations while the non-altered cohort was enriched for alterations in cell cycle-related genes previously associated with endocrine and cyclin-dependent kinase 4/6 inhibitor resistance.

Disappearing Signet Ring Cell Adenocarcinoma in Gastric Cancer Patients. (PubMed, Ann Surg Oncol)

These cases allude to the distinct pathways of carcinogenesis in T1a signet ring cell cancers. Potential factors that may underlie the spontaneous regression of these T1a cancers include complete removal at initial biopsy, immune clearance, and lack of survival advantage conferred by signet ring cell genetic alterations in these cases. Given their more indolent behavior at an earlier stage, we suggest that these lesions can be closely followed by endoscopy in select circumstances with thorough disease assessment and an experienced care team.

Real-world survival analysis demonstrated that patients with CCNE1-amplified gastric cancer had worse survival after trastuzumab for HER2-positive tumors, but better survival after immunotherapy. These data suggest that CCNE1-amplified gastric cancer has a distinct molecular and immune profile with important therapeutic implications, and therefore further investigation of CCNE1 amplification as a predictive biomarker is warranted.
