چکیده

A young woman with Li-Fraumeni syndrome (LFS) was referred to our hospital. On examination, multiple flat neoplasms were detected in addition to semi-pedunculated polyps. Restorative proctocolectomy was performed; one submucosal invasive cancer, two mucosal cancers, and several adenomas with high-grade dysplasia were detected. On immunohistochemical staining with p53, every part of all neoplasms, even the small adenomas, showed strong positive staining. Multiple flat neoplasms may be characteristic of patients with LFS and may have a much higher risk of rapid progression to invasive carcinomas than sporadic neoplasms. Thus, careful and frequent colonoscopy surveillance may be needed for patients with LFS.

Does PTEN gene mutation play any role in Li-Fraumeni syndrome?

Background: Li-Fraumeni syndrome (LFS) is one of the most serious hereditary cancer syndromes with a high risk of malignancy in childhood. This syndrome is an autosomal dominant cancer predisposing syndrome due to a germline mutation in the TP53 tumor suppressor gene.   Methods: In this study, a representative family case of Li-Fraumeni syndrome is described. The proband of this family ...

A Case of Late-Onset Li-Fraumeni-like Syndrome with Unilateral Breast Cancer

Li-Fraumeni syndrome (LFS) is a rare, inherited syndrome associated with increased risk of various early-onset tumors. Since the introduction of classic LFS criteria, various criteria have been proposed to include patients with incomplete LFS features, which make up Li-Fraumeni-like syndromes (LFL). Germline missense mutations of TP53 are the primary cause of LFS and LFL. Mutations mostly resid...

Li‐Fraumeni versus Pseudo‐Li‐Fraumeni Syndrome: Key Insights for Interpreting Next‐Generation Sequencing Reports in Patients with Suspected Cancer Predisposition Syndromes

Next-generation sequencing (NGS) of tumors and now circulating cell-free DNA is increasingly used to identify “actionable” genetic abnormalities. Detecting abnormalities offers opportunities for physicians and patients to qualify for therapeutic strategies that target the oncogenic lesions identified by NGS. However, NGS tumor-testing companies are not currently licensed to report germline alte...

Predisposition to pediatric and hematologic cancers: a moving target.

Our understanding of hereditary cancer syndromes in children, adolescents, and young adults continues to grow. In addition, we now recognize the wide variation in tumor spectrum found within each specific cancer predisposition syndrome including the risk for hematologic malignancies. An increased understanding of the genetic mutations, biologic consequences, tumor risk, and clinical management ...

Clinical response to a lapatinib-based therapy for a Li-Fraumeni syndrome patient with a novel HER2V659E mutation.

UNLABELLED Genomic characterization of recurrent breast and lung tumors developed over the course of 10 years in a 29-year-old patient with a germline TP53 mutation (Li-Fraumeni Syndrome) identified oncogenic alterations in the HER2 and EGFR genes across all tumors, including HER2 amplifications, an EGFR-exon 20 insertion, and the first-in-humans HER2V659E mutation showing a phenotypic converge...
