Molecular breast imaging (MBI), also called breast-specific gamma imaging (BSGI), has been an integral component of our breast imaging practice for over a decade. Unlike mammography and ultrasound that are based on anatomy, MBI is a physiologic approach to breast cancer detection. MBI detects additional foci of occult breast cancer in 9.0% of women with newly diagnosed breast cancer, has a high sensitivity for detecting high-risk lesions, and detects 98% of invasive breast cancer and 91.0% of ductal carcinoma in situ...

Neo-adjuvant chemotherapy (NAC) is administered in breast cancer treatment for downstaging of disease. Here, we determined the impact of response to NAC on breast reconstruction uptake. A prospective NAC and mastectomy database with or without reconstruction were reviewed with IRB approval. Univariable analyses were conducted using Kruskal-Wallis or Fisher's exact tests. Multivariable logistic regression was used to adjust for potential confounders. We identified 271 patients with unilateral breast cancer receiving NAC and either unilateral or bilateral mastectomy from 9/2013 to 5/2016...

BACKGROUND: The topic of trastuzumab therapy without chemotherapy in early breast cancer (EBC) has been repeatedly discussed at international consensus meetings, but is compromised by the lack of solid evidence from clinical studies. METHODS: An observational study database of patients with EBC receiving trastuzumab-containing (neo)adjuvant therapy was screened to identify those patients who did not receive cytostatic agents. RESULTS: Of 3935 patients, 232 (6%) were identified who received no chemotherapy, being characterized by older age, worse performance status, and/or less aggressive histology...

Purpose Cell-free DNA (cfDNA) offers the potential for minimally invasive genome-wide profiling of tumor alterations without tumor biopsy and may be associated with patient prognosis. Triple-negative breast cancer (TNBC) is characterized by few mutations but extensive somatic copy number alterations (SCNAs), yet little is known regarding SCNAs in metastatic TNBC. We sought to evaluate SCNAs in metastatic TNBC exclusively via cfDNA and determine if cfDNA tumor fraction is associated with overall survival in metastatic TNBC...

REVIEW
Tomasz Sarosiek
Breast cancer is the most commonly diagnosed malignancy in women around the globe. It is also the world's first cause of female deaths from cancer. With the introduction of screening programs in most developed countries, more and more cases of this cancer are diagnosed at local or localized stages, enabling radical treatment to be successful. At the same time, systemic treatment of early breast cancer is one of the most complex issues in clinical oncology. Because of the many prognostic factors that need to be taken into account when considering eligibility for treatment such as age, reproductive status (before or after menopause), type of cancer and severity of the disease, it is impossible to establish clear standards of conduct for many clinical situations...

Synovial sarcoma (SS) is a rare sarcoma driven by a translocation between SS18 and SSX 1, 2, or 4. With approximately 800 to 1,000 cases a year in the United States, it most commonly affects young adults between the ages of 15 and 30 years. The resultant tumors are either monophasic (pure sarcomas), biphasic (a combination or epithelioid and sarcomatous components), or poorly differentiated. The hybrid transcription factor SS18:SSX alters SWItch/Sucrose Non-Fermentable (SWI/SNF) chromatin remodeling and global methylation patterns that may allow for future therapeutic opportunities...

A Biazzo, M De Paolis
Osteosarcoma is a malignant bone tumor composed of mesenchymal cells producing osteoid and immature bone. Osteosarcoma is the most frequent primary malignant bone tumor, if we excluded myeloma, a haematologic disease. The incidence of osteosarcoma is 2-3/million/year, but is higher in adolescence, in which the annual incidence peaks at 8-11/million/year at 15-19 years of age. Local pain, followed by localized swelling and limitation of joint movement, are the typical signs and symptoms. Correct diagnosis can be achieved through a correct approach to the disease and the combination of clinical and radiographic aspects...

Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal and disseminating cancer resistant to therapy, including checkpoint immunotherapies, and early tumor resection and (neo)adjuvant chemotherapy fails to improve a poor prognosis. In a transgenic mouse model of resectable PDAC, we investigated the coordinated activation of T and NK cells in addition to gemcitabine chemotherapy to prevent tumor recurrence. Only neoadjuvant, but not adjuvant treatment with a PD-1 antagonist effectively supported chemotherapy and suppressed local tumor recurrence and improved survival involving both NK and T cells...

BACKGROUND: Next generation sequencing technology has facilitated mapping of the colorectal cancer genotype and furthered our understanding of metastogenesis. The aim of this study was to investigate for conserved and different mutations in the exomes of synchronously resected primary colorectal tumour and liver metastases. This information could potentially be utilised to guide the treatment of advanced disease with the help of biological information from the primary tumour. METHODS: We performed exome sequencing of synchronously resected primary colorectal cancer and colorectal liver metastases as well as normal colonic mucosa and liver parenchyma, from four patients who had received neo-adjuvant chemotherapy, at a depth of 50X using the Ion Proton platform...

PURPOSE: Body composition parameters including low muscle mass, muscle attenuation (which reflects muscle quality) and adipose tissue measurements have emerged as prognostic factors in cancer patients. However, knowledge regarding the possibility of excessive muscle loss during specific systemic therapies is unknown. We describe the changes in body composition and muscle attenuation (MA) during taxane- and anthracycline-based regimens and its association with overall survival (OS) in metastatic breast cancer patients...

RATIONALE: Burkitt lymphoma (BL) is a type of non-Hodgkin lymphoma that arises in the B-cells. Cavernous sinus involvement is rare, especially in adults. Here we report an unusual case of a 30-year-old HIV-positive woman with BL and cavernous sinus syndrome who also had intense bilateral breast uptake, related to menstrual cycle. Fluorine-18 2-fluoro-2-deoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) has been found to be useful in the management of BL. PATIENT CONCERNS: A 30-year old female patient presented with a history of diplopia and headache...
