Concurrent breast stroma sarcoma and breast carcinoma: a case report

<p>Abstract</p> <p>Introduction</p> <p>Breast cancer is one of the most important health problems in the world and affects a great number of women over the entire globe. This group of tumors rarely presents as bilateral disease and, when it does happen, normally occurs within the same histological type. We report a rare case of concurrent bilateral breast cancer with two different histology types, a breast carcinoma and a breast sarcoma, in a 42-year-old woman referred to our hospital.</p> <p>Case presentation</p> <p>A 42-year-old Caucasian woman admitted to our institute in August 1999, presented with a nodule in the left breast of 3.0 × 2.5 cm, and, in the right breast, one of 1.0 cm, suspected of malignancy and with a clinically negative armpit. Biopsies had revealed invasive mammary carcinoma (right breast) and sarcoma (left breast). She was submitted to bilateral modified radical mastectomy. A histological study showed an invasive mammary carcinoma degree II lobular pleomorphic type with invasion of seven of the 19 excised axillary nodes in the right breast and, in the left breast, a sarcoma of the mammary stroma, for which the immunohistochemistry study was negative for epithelial biomarkers and positive for vimentin. Later, she was submitted for chemotherapy (six cycles of 75 mg/m²5-fluorouracil, epirubicin and cyclophosphamide) followed by radiotherapy of the thoracic wall and axillary nodes on the left. Hormone receptors were positive in the tumor of the right breast, and tamoxifen, 20 mg, was prescribed on a daily basis (five years) followed by letrozole, 2.5 mg, also daily (five years). She presented no sign of negative evolution in the last consultation.</p> <p>Conclusion</p> <p>The risk of development of bilateral breast cancer is about 1% each year within a similar histological type, but it is higher in tumors with lobular histology. In this case, the patient presented, simultaneously, two histologically distinct tumors, thus evidencing a rare situation.</p

Standardized and reproducible methodology for the comprehensive and systematic assessment of surgical resection margins during breast-conserving surgery for invasive breast cancer

<p>Abstract</p> <p>Background</p> <p>The primary goal of breast-conserving surgery (BCS) is to completely excise the tumor and achieve "adequate" or "negative" surgical resection margins while maintaining an acceptable level of postoperative cosmetic outcome. Nevertheless, precise determination of the adequacy of BCS has long been debated. In this regard, the aim of the current paper was to describe a standardized and reproducible methodology for comprehensive and systematic assessment of surgical resection margins during BCS.</p> <p>Methods</p> <p>Retrospective analysis of 204 BCS procedures performed for invasive breast cancer from August 2003 to June 2007, in which patients underwent a standard BCS resection and systematic sampling of nine standardized re-resection margins (superior, superior-medial, superior-lateral, medial, lateral, inferior, inferior-medial, inferior-lateral, and deep-posterior). Multiple variables (including patient, tumor, specimen, and follow-up variables) were evaluated.</p> <p>Results</p> <p>6.4% (13/204) of patients had positive BCS specimen margins (defined as tumor at inked edge of BCS specimen) and 4.4% (9/204) of patients had close margins (defined as tumor within 1 mm or less of inked edge but not at inked edge of BCS specimen). 11.8% (24/204) of patients had at least one re-resection margin containing additional disease, independent of the status of the BCS specimen margins. 7.1% (13/182) of patients with negative BCS specimen margins (defined as no tumor cells seen within 1 mm or less of inked edge of BCS specimen) had at least one re-resection margin containing additional disease. Thus, 54.2% (13/24) of patients with additional disease in a re-resection margin would not have been recognized by a standard BCS procedure alone (P < 0.001). The nine standardized resection margins represented only 26.8% of the volume of the BCS specimen and 32.6% of the surface area of the BCS specimen.</p> <p>Conclusion</p> <p>Our methodology accurately assesses the adequacy of surgical resection margins for determination of which individuals may need further resection to the affected breast in order to minimize the potential risk of local recurrence while attempting to limit the volume of additional breast tissue excised, as well as to determine which individuals are not realistically amendable to BCS and instead need a completion mastectomy to successfully remove multifocal disease.</p

diagnosis of extracranial vertebral artery dissections

The purpose of this study was to evaluate the role of color Doppler sonography (CDS) in the diagnosis of extracranial vertebral artery dissections (EVADs). One hundred and fifty consecutive patients (age range 21-51years, mean 44years) with a clinical suspicion of vertebral artery dissection (VAD) were included in this study. All patients underwent CDS of vertebral arteries as the first-line imaging modality. Cervical T1-weighted fat-saturated axial MR images served as the gold standard. Of the 150 patients with a clinical suspicion of VAD, 27 patients were ultimately diagnosed with EVADs based on fat-saturated T1-weighted MR imaging. MR imaging was considered positive when crescentic hyperintensity (methemoglobin signal) was demonstrated at the wall of the vertebral artery. CDS was positive in 21 of these 27 patients and revealed either intramural hematoma or a dissecting membrane with two lumina. The most frequent site of involvement was the V1 to proximal V2 segment. The sensitivity, specificity, and positive and negative predictive values of CDS in the diagnosis of EVADs were 77.8, 98.4, 91.3, and 95.3%, respectively. CDS is a reliable diagnostic tool in the diagnosis of EVADs.C1 [Yilmaz, Cengiz; Gorgulu, Feride Fatma; Oksuzler, Fatma Yasemin; Koc, Ayse Selcan] Univ Hlth Sci, Adana Hlth Practice & Res Ctr, Dept Radiol, Adana, Turkey.[Arslan, Muhammet] Pamukkale Univ, Dept Radiol, Fac Med, Denizli, Turkey.[Oksuzler, Mahmut] Medline Hosp, Dept Radiol, Adana, Turkey.[Keskek, Sakir Ozgur] Univ Hlth Sci, Adana Hlth Practice & Res Ctr, Dept Internal Med, Adana, Turkey
