To describe the clinicopathological profile of breast cancer patients and association with excess body weight. Methods: This was a descriptive observational study of 126 women with breast cancer lesions treated between 2015 and 2017 at a cancer referral hospital for 27 municipalities in southwestern Paraná. Patients were categorized according to age at diagnosis, body mass index, menopausal status, molecular subtyping of tumors, histological characteristics, and risk stratification. Data were coded for analysis using the Statistical Package for Social Sciences (SPSS) 22.0.0 software. Results: There were 126 patients diagnosed with breast cancer and more than half of these had an excessive body weight (mean BMI 27.5kg/m 2 ). There was a predominance of the triple negative molecular subtype in overweight women; they also had a higher frequency of tumors larger than 2cm and high histological grade tumors. There were significant associations in the overweight/ obese subgroup such as tumors in the intermediate grade luminal B subtype, presence of angiolymphatic emboli, and a high-risk of disease recurrence. Conclusion: The data indicate that being overweight is a determinant of worse prognosis in women with breast cancer in southwestern Paraná.
Objective This study evaluated the risk of the hereditary breast and ovarian cancer (HBOC) syndrome in patients with breast cancer by using the Family History Screening 7 (FHS-7) tool, a validated low-cost questionnaire with high sensitivity able to screen the HBOC risk in the population. Methods Women diagnosed with breast cancer (n = 101) assisted by the Unified Health System at the 8th Regional Health Municipal Office of the state of Paraná answered the FHS-7, and the results were analyzed using IBM SPSS Statistics for Windows, Version 25.0. software (IBM Corp., Armonk, NY, USA). Results The risk of HBOC was 19.80% (n = 20). Patients at risk exhibited aggressive tumor characteristics, such as high-grade tumors (30%), presence of angiolymphatic emboli (35%), and premenopausal at diagnosis (50%). Significant associations between the prevalence of high-grade tumors were observed in women younger than 50 years at diagnosis with HBOC (p = 0.003). Conclusion Our findings suggest a possible family inheritance associated with worse clinical features in women with breast cancer in this population, indicating that HBOC investigation can be initially performed with low-cost instruments such as FHS-7.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
