Localization of sentinel lymph node in breast cancer. A prospective study
2014
Abstract Introduction Sentinel Lymph Node Biopsy (SLNB) is the standard of care for staging axillary lymph nodes in women with breast cancer and clinically negative nodes. It is associated with reduced arm morbidity, moderated or severe lymphoedema, and a better quality of life in comparison with standard axillary treatment. Unfortunately, skip metastases makes all minimally invasive approaches, such as axillary sampling, unreliable. The aim of the present clinical prospective study is to evaluate the position of SLN in an important number of cases and establish the real incidence of skip metastases in clinically node-negative patients. Patients and methods A cohort of 898 female patients w…
Prognostic significance of the immunocytochemical detection of contaminating tumor cells (CTC) in apheresis products of patients with high-risk breas…
2001
The aim of this study was to determine whether the detection of CTC in the apheresis product contribute significantly to treatment failure of patients with high-risk breast carcinoma treated with high-dose chemotherapy (HDC) and stem cell transplantation (SCT). Patients were with stage II and III adenocarcinoma of the breast with > or = 10 axillary lymph nodes affected after primary surgery (> or = 10 N+) who had received HDC with SCT. We analyzed retrospectively the presence of CTC as assessed by immunocytochemistry (ICC) in the apheresis products obtained after standard adjuvant chemotherapy. We compared the clinical outcome of patients who received HDC and SCT with or without CTC-positiv…

Pro-Inflammatory Cytokines in Elective Flap Surgery
2006
Surgical trauma releases inflammatory mediators such as pro-inflammatory cytokines. In this prospective, controlled, randomized trial we investigated the release of pro-inflammatory cytokines and monocyte/macrophage activation in patients scheduled for breast reconstruction after mastectomy. Patients were allocated to one of three surgical procedures, differing in complexity and in the need for implants used for reconstruction.Thirty mastectomized women underwent delayed breast reconstruction with the lateral thoracodorsal flap (LTD), the latissimus dorsi flap (LD), or the pedicled transverse rectus abdominis muscle flap (TRAM). Blood samples for TNF, IL-6, IL-8, neopterin, C-reactive prote…
Characterisation of indeterminate focal breast lesions on grey-scale ultrasound: role of ultrasound elastography.
2011
PURPOSE: This study was undertaken to evaluate the role of ultrasound (US) elastography in characterising focal breast lesions classified as indeterminate on B-mode US. MATERIALS AND METHODS: Eighty-four focal breast lesions, 64 benign and 20 malignant (mean diameter, 15.1 mm), detected but not characterised on B-mode US in 72 women, Breast Imaging Reporting and Data System (BI-RADS) US category 3 (n=56) or category 4 (n=28), were studied with US elastography and classified in consensus by two radiologists according to a five-point colour scale. Sensitivity, specificity and positive and negative predictive values (PPV and NPV) of US elastography compared with conventional US were calculated…
Epidermal growth factor receptor in human breast cancer: Correlation with cytosolic and nuclear ER receptors and with biological and histological tum…
1990
Epidermal growth factor receptor (EGFr) and cytosolic (cER) and nuclear (nER) estradiol receptors were quantified in 220 primary breast cancers. The EGFr was significantly more frequent (chi 2 = 5.9; P less than 0.025) and its concentration was significantly higher (P less than 0.001) among ER- tumors than in ER+ tumors. There was a significantly greater proportion (chi 2 = 6.4; P less than 0.05) of node involvement in EGFr+/ER+ tumors than in EFGr-/ER+. Increases in the proportion of EGFr+ in ER- tumors are parallel to Scarff-Bloom scores (chi 2 = 6.1; P less than 0.05) and there is a significant trend (Spearman rs = 0.25; P less than 0.05) towards increased EGFr concentrations with histol…
Imaging findings of primary breast sarcoma : results of a first multicenter study
2016
Abstract Purpose To investigate imaging findings in patients with primary breast sarcoma (PBS). Materials and methods A retrospective search in the databases of 10 radiological departments in Germany from 2000 to 2011 was performed. Only histologically proven cases of PBS were included into the study. Mammography was available in 31 patients (33 lesions), ultrasound images in 24 patients (24 lesions), and for 10 patients (14 lesions) magnetic resonance imaging (MRI) of the breast was performed. The breast findings were classified according to the American College of Radiology Breast Imaging Reporting and Data Systems (BI-RADS) 5th edition categories. Collected data were evaluated by means o…
Intratissular expansion–mediated, serial fat grafting: A step-by-step working algorithm to achieve 3D biological harmony in autologous breast reconst…
2016
Background Breast reconstruction involves the use of autologous tissues or implants. Occasionally, microsurgical reconstruction is not an option because of insufficient donor tissues. Fat grafting has become increasingly popular in breast surgery. The challenge with this technique is how to reconstruct a stable and living “scaffold” that resembles a breast. Methods Breast reconstruction (n = 7) was performed using intratissular expansion with serial deflation–lipofilling sessions. Mean age of the patients was 41 years (22–53). The expander generated a vascularized capsule at 8 weeks, which demarcated a recipient site between the skin and the capsule itself, and functioned as a vascular sour…
The value of intraoperative frozen section examination of sentinel lymph nodes in surgical management of breast carcinoma.
2009
PURPOSE: In breast cancer staging, the need for intraoperative sentinel lymph node (SLN) evaluation has still not been adequately established. This study investigates the impact of intraoperative frozen section (FS) evaluation of SLN to avoid subsequent axillary lymph node dissection (ALND) in patients with positive SLN. METHODS: A retrospective review of 364 breast cancer patients undergoing SLN biopsy with intraoperative FS evaluation of SLN was performed. RESULTS: Sensitivity and accuracy of FS examination of SLN were 76.4% and 94.2%, respectively. The sensitivity was significantly higher in larger tumors (p < 0.01). No significant correlation was found between FS and histologic type. A …
Human breast areolae as scent organs: morphological data and possible involvement in maternal-neonatal coadaptation.
2006
In humans, areolar skin glands (AG) enlarge during pregnancy and lactation. Their role in mother-infant interactions may pertain to protective, mechanical, and communicative functions. It was questioned here whether more profuse AG could be related to more optimal adaptation to breastfeeding. A morphological study of the areolae was undertaken between birth and day 3 to assess the number, secretory status, and spatial distribution of AG. These data were related to infants' weight variation, mothers' perception of their infant's behavior at breast, and time between delivery and onset of lactation. AG were seen in virtually all women but with great interindividual variations; their areolar di…
