Subclinical breast lesions

Recent years have witnessed a dynamic development of mammary gland imaging techniques, particularly ultrasonography and magnetic resonance imaging. A challenge related to these studies is the increase in the precision of the anatomical assessment of breast, particularly for early detection of subclinical lesions, performance of ultrasound- guided biopsy procedures, and accurate preoperative location of pathological lesions so as to optimize the surgical treatment. Ultrasound imaging is a primary and baseline diagnostic procedure the patient with suspected pathological lesions within breast is referred to by the surgeon...

PURPOSE: Adjuvant radiotherapy and chemotherapy for breast cancer have been related to transient ischemic attacks and stroke. To date, no studies have investigated the relationship between these adjuvant therapies and subclinical cerebral small-vessel disease in survivors of breast cancer. We compared white matter lesion (WML) volume and prevalence of brain infarctions and cerebral microbleeds (CMBs) between breast cancer survivors exposed to adjuvant radiotherapy and chemotherapy (aRCeBCSs) for primary disease and a population-based reference group...

This review aims to analyse the published data on the prevalence and clinical significance of breast incidental F18-FDG uptake detected by PET or PET/CT (BIU). A comprehensive computer literature search of the PubMed/MEDLINE, Scopus and Embase databases for studies on BIU published through July 2013 was performed. Pooled prevalence and malignancy risk of BIU were calculated. The literature search revealed 42 articles, and 17 were selected. One study was excluded because of data overlap but four additional studies were found screening the references...

A multiantigen multipeptide vaccine, targeting proteins expressed in preinvasive breast lesions, can stimulate type I CD4(+) T cells which have been shown to be deficient in both patients with breast cancer and mice that develop mammary tumors. Transgenic mice (TgMMTV-neu) were immunized with a multiantigen peptide vaccine specific for neu, insulin-like growth factor-binding protein 2 and insulin-like growth factor receptor-I at a time when some of the animals already had preinvasive lesions (18 weeks of age)...

Gynecomastia is the most bothersome side effect in men taking antiandrogens. It is exceptionally severe and distressing physically and mentally as in the reported case. A man, aged 63, with a history of a well-treated macroprolactinoma, was referred in 2004 for gynecomastia that appeared after treatment by microsurgery, radiotherapy and flutamide for a lesion suspected to be prostate cancer. Clinical examination was normal except for huge enlargement of the breasts. Mammography and breasts MRI did not show any tumor...

OBJECTIVE: Previous few studies have shown that resistin is significantly elevated in breast cancer (BC) patients. Therefore, we investigated whether serum resistin could be used as a potential diagnostic and prognostic tool for postmenopausal BC (PBC), taking into account clinicopathological features, serum tumor markers, anthropometric, metabolic, and, for the first time, inflammatory parameters. METHODS: Serum resistin, tumor markers (CA 15-3 and CEA), metabolic, anthropometric and inflammatory parameters (TNF-α, IL-6, hsCRP) were determined in 103 postmenopausal women with incident, pathologically confirmed, invasive BC, 103 controls matched on age and time of diagnosis, and 51 patients with benign breast lesions (BBL)...

BACKGROUND: Breast cancer is a major cause of cancer-related morbidity and mortality in Indian women. Most cases present late and thus survival in Indian patients is poor compared to the western world. In the absence of a screening, early detection of breast cancer is a challenge in Indian subcontinent. METHOD: Though much is known about management of any palpable lump in breast, clear guidelines in dealing with non-palpable lesions of breast is still obscure. Careful imaging of breast followed by assignment of standard Breast Imaging Reporting and Data Systems (BIRADS) category to the finding can go in a long way to predict chances of malignancy in a non-palpable breast lesion (NPBL)...

PURPOSE: To determine the diagnostic performance of radiological evaluation of the margins of surgical specimens from lumpectomies for subclinical malignant breast lesions. MATERIALS AND METHODS: Retrospective study in two French hospitals including all patients who had a non-palpable in situ (ISDC) or invasive (IDC) ductal carcinoma treated by lumpectomy after radiological localisation. For the analysis, the lesions were divided into two groups depending on the majority component in the definitive histological examination: ISDC or IDC...

OBJECTIVES: To assess the ablative effectiveness, the oncological and cosmetic efficacy of image-guided percutaneous cryoablation in the treatment of single breast nodules with subclinical dimensions after identification with ultrasonography (US), mammography, magnetic resonance (MRI) and characterization by vacuum assisted biopsy. MATERIALS: Fifteen women with a mean age of 73 ± 5 years (range 64-82 years) and lesion diameter of 8 ± 4 mm were undergoing cryotherapy technology with a single probe under US-guidance associated with intra-procedural lymph-node mapping and excision of the sentinel node...

BACKGROUND: The new imaging technology made available today allows for an early detection of small subclinical breast lesions which frequently call for guided presurgical micro-histology. PURPOSE: To evaluate the relationship between vacuum-assisted breast biopsy (VABB) histopathological diagnoses and mammographic findings in non-palpable breast lesions. MATERIAL AND METHODS: The breast lesions of 1393 women who had received consecutive screening mammograms between 2001 and 2007 were assessed by VABB...

OBJECTIVE: To investigate the value of guide wire location under mammography for a resection of subclinical breast lesions. METHODS: A total of 79 patients presenting with abnormal mammography but unpalpable lesions received a guide wire pre-operative location under mammography. And 82 lesions were successfully located and resected for pathological examination. RESULTS: All 82 lesions were located with a high accuracy. The pathological examination revealed breast fibroma (n = 4), mammary gland hyperplasia with calcification (n = 58), intraductal papilloma (n = 2), fat necrosis with calcification (n = 3), mammary atypical hyperplasia (n = 5), breast inflammation (n = 1) and breast cancer (n = 9)...

OBJECTIVE: This study aimed to determine the accuracy of specimen radiography in evaluating the surgical margins of impalpable breast carcinoma. DESIGN AND SETTING: Retrospective study from June 2009 to June 2010 in Orleans Hospital Center. PATIENTS AND METHODS: The study involved patients with impalpable in situ breast carcinoma diagnosed by mammography. Only patients with larger in situ carcinoma than invasive carcinoma were included. Patients underwent a breast conserving surgery after preoperative localization of the lesion...

PURPOSE: This study sought to evaluate the accuracy of vacuum-assisted biopsy (VAB) in the diagnosis of atypical ductal hyperplasia (ADH) by determining the rate of VAB underestimation compared with definitive histology. In addition, an attempt was made to identify parameters that could help determine the most appropriate patient management. MATERIALS AND METHODS: We retrospectively reviewed 1,776 VAB procedures performed between November 1999 and January 2008 for suspicious subclinical breast lesions visible only at mammography...

INTRODUCTION: Metastatic cancer is rarely found in the thyroid (only 2-3% of malignant tumours found in that gland); primary sources usually including breast, kidney, and lung tumours. CASES REPORTS: Two cases of advanced breast cancer with thyroid metastases in female patients are presented. The similarities between these two cases included: 1) postmenopausal age; 2) diagnosis based on result of FNAB (numerous groups of cells with epithelial phenotype strongly implying metastatic breast cancer); 3) thyroid function - overt hyperthyroidism in the first woman and subclinical hyperthyroidism in the second one; 4) the presence of nodular goitre in clinical examination, the occurrence of many nodular solid normoechogenic lesions with calcifications in both thyroid lobes in US; and 5) negative antithyroid antibodies...

BACKGROUND: Magnetic resonance imaging (MRI) is more often considered to guide, evaluate or select patients for partial breast irradiation (PBI) or minimally invasive therapy. Safe treatment margins around the MRI-visible lesion (MRI-GTV) are needed to account for surrounding subclinical occult disease. PURPOSE: To precisely compare MRI findings with histopathology, and to obtain detailed knowledge about type, rate, quantity and distance of occult disease around the MRI-GTV...

PURPOSE: The main objective was to assess contributions and limits of surgical clips combined with computed tomography to define the tumor bed after conservative treatment of breast cancer. This retrospective observational study enrolled 16 patients treated by lumpectomy with surgical clips placed in the tumor bed. PATIENTS AND METHODS: We assessed the difficulties in localizing the tumour bed based on collected data (i.e. clinical description, mammography, ultrasound examination, surgical procedure and pathology data)...

Papillomaviruses are small DNA viruses that infect and multiply in cutaneous or mucosal epithelial tissue. Human papillomavirus (HPV) 16 and 18 cause more than 99% of cervical carcinomas. Simultaneous presence of HPV is found in cervical intraepithelial neoplasia, vaginal intraepithelial neoplasia, vaginal and anal cancer. Invasive vulvar squamous cell carcinoma in younger women under the age of 50 are also associated with HPV. Most of the penile lesions are subclinical and the high prevalence of high-risk HPV suggests that they constitute a reservoir for high-risk HPV...

BACKGROUND: Breast cancer is the most common gynecologic malignancy worldwide. Localization under ultrasound guidance or mammography prior to biopsy is one of the procedures used for diagnosis of subclinical malignant or premalignant lesions. OBJECTIVE: To describe techniques for localization by mammography or ultrasound at our institution, prior to excisional breast biopsy. MATERIAL AND METHODS: Localization under ultrasound guidance or mammography from July 1 to December 31, 2008 at the HospitalAngeles del Pedregal...

PURPOSE: To investigate clinical implications of FDG uptake in the thyroid glands in patients with advanced breast carcinoma by comparing metabolic and morphologic patterns on positron emission tomography (PET)/computed tomography (CT). METHODS: The institutional review board waived the requirement for informed consent. A retrospective analysis was performed in 146 women (mean age 54 years) with advanced breast carcinoma who received systemic treatment. All patients underwent PET-CT before and after treatment...

Among breast cancer patients, 20% to 45% develop malignant lesions following their initial treatment. This relapse may occur after an apparent remission period that can range from years to several decades. Clinical observations suggest that breast-derived malignant cells have the ability to survive subclinically for a very long period of time before eventually resuming proliferation and forming detectable lesions. While the precise molecular events that correspond to this dormant phenotype remain poorly understood, data published during the last 10 years have underlined an important role of integrin proteins in the regulation of this phenomenon...
