Extra-nodal extension of sentinel lymph node metastasis is a marker of poor prognosis in breast cancer patients: A systematic review and an explorato…
2016
Invasive breast cancer is the most common malignancy in women. Its most common site of metastasis is represented by the lymph nodes of axilla, and the sentinel lymph node (SLN) is the first station of nodal metastasis. Axillary SLN biopsy accurately predicts axillary lymph node status and has been accepted as standard of care for nodal staging in breast cancer. To date, the morphologic aspects of SLN metastasis have not been considered by the oncologic staging system. Extranodal extension (ENE) of nodal metastasis, defined as extension of neoplastic cells through the nodal capsule into the peri-nodal adipose tissue, has recently emerged as an important prognostic factor in several types of …
The accuracy of sentinel lymph-node biopsy in breast cancer after previous excisional biopsy
2013
Scopo: La biopsia del linfonodo sentinella (BLS) nel carcinoma della mammella con linfonodi ascellari clinicamente negativi è considerato la migliore scelta per stadiare il cavo ascellare. Inizialmente una precedente biopsia escissionale del carcinoma era considerata una controindicazione. Esaminiamo il tasso di successo della BLS e la incidenza della recidiva a livello ascellare in pazienti con carcinoma della mammella precedentemente sottoposti a biopsia escissionale del tumore. Pazienti e metodi: 858 pazienti con carcinoma della mammella sono stati sottoposti a BLS e i pazienti con linfonodi sentinella metastatici a svuotamento del cavo ascellare; 82 pazienti erano stati sottoposti prece…
Perfluoroalkyl substances in Breast milk, infant formula and baby food from Valencian Community (Spain)
2016
Environmental and human exposures to perfluoroalkyl substances (PFASs) are of emerging concern since they are persistent and bioaccumulative. The present study reports PFASs levels in human milk, infant formulas and baby food (dry cereals and pots) from the Valencian Community (Spain) in order to evaluate the infant exposure to these substances through the diet. The results show that perfluorobutanoic acid (PFBA) and perfluorooctanoic acid (PFOA) were in all the samples of the four selected matrices (except PFOA in one sample of dry cereal baby food). Perfluoroheptanoic acid (PFHpA) and perfluorodecanoic acid (PFDA) were also detected in 70% of the breast milk samples. In infant formulas, P…
Probiotic characterization of Lactobacillus strains isolated from breast milk and employment for the elaboration of a fermented milk product
2021
Abstract A total of seven strains of lactic acid bacteria (LAB) isolated from breast milk, were investigated for their probiotic properties. Lactobacillus plantarum 5H1 and 5L1 were selected for their beneficial properties and used for probiotic fermented milk manufacture. The fermentation parameters (pH and lactic acid) and LAB viability during fermented milk processing and storage were evaluated. The results showed that the strains had a broad spectrum of antimicrobial activity against pathogenic bacteria and toxigenic fungi. These also evidenced capacity of adhesion and reduction of Salmonella adhesion to Caco-2 cells. During milk fermentation process, an increase in lactic acid content,…
The use of stereotaxic cytology in the diagnosis of non-palpable breast lesions. Personal experience
1999
Background and aims. The increasingly frequent use of mammography for the early diagnosis of breast cancer and the consequent identification of mammary lesions at a preclinical stage raises the fundamental problem of the differential diagnosis between non-suspected non-palpable lesions (NPL) which can therefore be monitored over time and suspected NPL or definite carcinoma requiring histological confirmation and surgical biopsy. The diagnostic accuracy of mammography alone is not sufficiently high to differentiate benign lesions from malignant or strongly suspected ones. The use of surgical biopsy in the event of suspected NPL could be significantly reduced by the use of stereotaxic cytolog…
A method to reduce the FP/imm number through CC and MLO views comparison in mammographic images
2008
In this paper we propose a method to reduce the FP/imm number through CC and MLO mammographic views comparison of the same patient. The proposed solution uses the symmetry properties of the breast to compute a geometric transformation that permits to represent the two images in comparable coordinates systems. Through this method, potential pathological ROIs of one of the projections are correlated with the ROIs in the second view. To show the effectiveness of the result we apply the method on a dataset composed of 112 couples of pathological images. Experiments shows that method enables a reduction by up to 700/0 of the FP/imm number detected after the classification step

Multigene panel testing in Hereditary Breast and Ovarian Cancer: an effective liquid biopsy approach to identify mutations in genes involved in the H…
2021
Background: Hereditary breast and ovarian cancer (HBOC) syndrome is an autosomal dominant inherited disorder that include 5–7% of all breast cancer (BC) cases and 10-15% of all ovarian cancer (OC) cases. BRCA1 and BRCA2 are the most common genes associated to HBOC syndrome. However, hereditary syndrome could be associated with germline PVs in several high- and moderate-risk genes. In recent years, Next-Generation Sequencing (NGS) has allowed to study multiple genes simultaneously, to reduce analysis costs, to led to an explosion of genetic data, and to offer more information to patients. Methods: We retrospectively collected and analyzed to BRCA1/2 test 876 patients affected by BC and OC (5…
Odontoiatria di genere: la condizione femminile nella pratica odontoiatrica
2014
Obiettivi: scopo del presente studio è quello di esaminare la condizione femminile in relazione alla professione odontoiatrica, quelle condizioni patologiche orali che possono colpire in particolare il sesso femminile e i trattamenti relativi. Materiali e metodi: oltre alla propria esperienza e al contributo personale, sono state effettuate ricerche sui motori di ricerca scientifica PubMed, Embase e Scopus. Risultati e conclusioni: è stata esaminata la figura della odontoiatra donna e la sua collocazione nell'ambito professionale, nonché le sue caratteristiche lavorative sia in relazione ai pazienti sia in relazione alla propria famiglia. Sono state analizzate poi le più comuni condizioni p…
Clinical features of the impact of eating disorders on the results of 13C-methacetin breath test for assessment of liver function in girls with anore…
2019
Introduction: This study was designed to assess the influence of chosen aspects of anorexia nervosa eating disorders (AN ED) on 13C-methacetin breath test (MBT) results. Material and methods: We investigated a group of 81 girls, including 41 patients with confirmed diagnosis of AN ED. The study group was divided in two subgroups. According to the DSM-5 classification, 25 underweight patients met the criteria of anorexia nervosa (AN), and 16 girls with BMI value > 5th percentile for age and sex were diagnosed as atypical anorexia nervosa (AAN). Laboratory tests assessing the liver function and the MBT were performed in all the participants of the study. Results: In all healthy females the va…
