Germline TP53 mutations predispose individuals to multiple cancers and are associated with Li-Fraumeni/Li-Fraumeni-Like Syndromes (LFS/LFL). The founder mutation p.R337H is detected in 0.3% of the general population southern Brazil. This an increased risk childhood adrenal cortical carcinoma (ACC) but also common Brazilian LFS/LFL families. Breast Cancer (BC) one most diagnosed carriers. We have assessed prevalence two groups: (1) 59 BC affected women a familial history (FH) suggestive...

Breast cancer is a significant public health problem worldwide and the development of tools to identify individuals at-risk for hereditary breast syndromes, where specific interventions can be proposed reduce risk, has become increasingly relevant. A previous study in Southern Brazil shown that family history suggestive these syndromes may prevalent at primary care level. Development simple sensitive instrument, easily applicable units, would particularly helpful underserved communities...

BACKGROUND Pediatric cancers are a feature in patients with Li‐Fraumeni syndrome and its variant Li‐Fraumeni–like (LFS/LFL). To the best of authors' knowledge, TP53 germline mutations currently only molecular defect known to be associated this disease. Recently, specific mutation gene, p.R337H, has been reported at high prevalence Brazil. METHODS The LFS/LFL was investigated children cancer who were diagnosed tumors on spectrum small consecutive series controls without cancer. p.R337H other...

Low rates of germline genetic testing (GGT) for breast cancer (BC) have been reported globally, with limited data from low- and middle-income countries (LMICs). In this study, we used real-world to assess the GGT rate BC in an LMIC identified barriers its use. We analyzed 2,974 newly diagnosed patients AMAZONA III largest Brazilian multicenter, prospective cohort. were determined entire cohort high-risk hereditary group (HR), defined by National Comprehensive Cancer Network criteria, between...

Breast cancer (BC) is a major public health problem, with rising incidence in many regions of the globe. Although mortality has recently dropped developed countries, death rates are still increasing some developing as seen Brazil. Among reasons for this phenomenon lack structured screening programs, long waiting period between diagnosis and treatment, access to services large proportion Brazilian population. Since 2004, an intervention study cohort women Southern Brazil, denominated Porto...

Abstract Background: Adherence to breast cancer screening is a key element ensure effectiveness of programs aiming at downstaging cancer. In this study, we evaluated adherence program and its predictors in underserved women southern Brazil. Methods: Attendance the program, which based on yearly mammogram clinical examination, was prospectively. Mean time frames between visits were calculated. Possible (defined as mean intervals ≤18 mo), such socioeconomic indicators health/lifestyle...

Germline mutations in TP53 are the underlying defect of Li-Fraumeni Syndrome (LFS) and Li-Fraumeni-like (LFL) Syndrome, autosomal dominant disorders characterized by predisposition to multiple early onset cancers. In Brazil, a variant form LFS/LFL is commonly detected because high prevalence founder mutation at codon 337 (p.R337H). The p53 protein exerts roles regulation oxidative metabolism cellular anti-oxidant defense systems. Herein, we analyzed redox parameters blood samples from...

The purpose of this study was to evaluate the association between apolipoprotein E (APOE) allelic frequency, serum lipoproteins and breast cancer (BC). We conducted a nested case-control within cohort including 47 cases 165 controls. Polymerase chain reaction-restriction fragment length polymorphism analyses APOE were performed. In general, participants with genotype alleles e2 e3 tended have lower triglycerides, total cholesterol low‑density lipoprotein levels higher high‑density (HDL)...

Rare germline mutations in TP53 (17p13.1) cause a highly penetrant predisposition to specific spectrum of early cancers, defining the Li-Fraumeni Syndrome (LFS). A mutation at codon 337 (p.Arg337His, c1010G>A) is found about 0.3% population Southern Brazil. This associated with partially LFS traits and patients cancers unselected for familial history. To characterize extended haplotypes carrying mutation, we have genotyped 9 short tandem repeats on chromosome 17p 12 trios Brazilian...
