Nipple-sparing mastectomies (NSMs) are increasingly used in the surgical treatment of patients with breast cancer and for prevention of breast cancer. The present study was performed to review the outcomes of patients undergoing NSMs at a single large university setting. A retrospective chart review was performed on all patients undergoing NSMs from 2008-2014. Charts were reviewed for demographic data and patient characteristics. Tumor and breast size, cancer recurrence and complications were also evaluated...

Dermatofibrosarcoma protuberans (DFSP) is a locally invading tumor, characterized by the presence of the collagen type I α 1 (COL1A1)-platelet-derived growth factor (PDGF) β fusion gene. We herein report the case of a 31-year-old man with a history of resection of an abdominal wall DFSP. The patient presented with chest pain and a computed tomography scan revealed a large mass in the posterior mediastinum and another mass in the right lung. The mediastinal mass was a sarcomatous lesion expressing the COL1A1-PDGFβ fusion gene, suggesting that it represented a metastasis of the DFSP following fibrosarcomatous (FS) transformation...

We describe our approach to resect a Pancoast tumor with thoracoscopic assistance in a partitioned incision. We used the LigaSure vessel-sealing system under thoracoscopy in chest wall resection for Pancoast tumor. This approach is of great utility: easy-to use and less invasive for Pancoast tumor resection.

Local drug delivery of Doxorubicin (Dox) with thermosensitive liposomes (TSL) and hyperthermia (HT) has shown preclinically to achieve high local drug concentrations with good therapeutic efficacy. Currently, this is clinically studied for treatment of chest wall recurrence of breast cancer, however with various outcomes. This study examines the potency of neoadjuvant TSL HT combination therapy in two orthotopic mouse models of human breast cancer, MDA-MB-231 and T-47D, which morphologically correlate to mesenchymal and epithelial phenotypes, respectively...

BACKGROUND: Pre-operative measurements from the skin to a wire-localized breast lesion can differ from operating room measurements. This study was designed to measure the discrepancies and study factors that may contribute to wire movement. METHODS: Prospective data were collected on patients who underwent wire localization lumpectomy. Clip and hook location, breast size, density, and direction of wire placement were the main focus of the analysis. RESULTS: Wire movement was more likely with longer distance from skin to hook or clip, larger breast size (especially if "fatty"), longer time between wire placement and surgery start time, and medial wire placement in larger breast...

A 59-year-old man was referred to the Kochi Medical School Hospital due to left shoulder pain. Physical examination revealed a nodular, painful mass lesion in the subcutaneous tissue of the right chest wall, with a diameter of ~2 cm. Esophagogastroduodenoscopy revealed a large ulcerated tumor in the lower gastric body near the lesser curvature, and biopsy specimens of the gastric and humeral lesions revealed poorly differentiated adenocarcinoma. Abdominal computed tomography revealed multiple low-density lesions in the liver and a well-defined, 2...

Spinal schwannomas are benign intradural extramedullary tumors arising from spinal nerve root sheath. They are usually solid or heterogeneously solid. Totally cystic schwannomas are rare entities. Herein, we report a 60-year-old male presenting with backache radiating along the chest wall and weakness of both lower limbs. He had spastic paraparesis. Magnetic resonance imaging revealed a cystic mass in the thoracic region. At operation, the cystic mass was seen to be attached to D4 dorsal rootlets. It was excised in toto and histopathology confirmed it to be a schwannoma...

INTRODUCTION/BACKGROUND: Treatment for HER2-postitive breast cancer often includes trastuzumab, breast/chest wall (CW) radiation (RT), and anthracyclines, all of which have cardiac toxicity. We aimed to evaluate the relationship between heart dose and acute left ventricular ejection fraction (LVEF) changes in patients who received concurrent trastuzumab and breast/CW RT with and without anthracycline use. PATIENTS AND METHODS: We retrospectively reviewed all nonmetastatic breast cancer patients from 2008 to 2015 who received concurrent trastuzumab and breast/CW RT...

Methionine dependence is due to the overuse of methionine for aberrant transmethylation reactions in cancer. Methionine dependence may be the only general metabolic defect in cancer. In order to exploit methionine dependence for therapy, our laboratory previously cloned L-methionine α-deamino-γ-mercaptomethane lyase [EC 4.4.1.11]). The cloned methioninase, termed recombinant methioninase, or rMETase, has been tested in mouse models of human cancer cell lines. Ewing's sarcoma is recalcitrant disease even though development of multimodal therapy has improved patients'outcome...

Locoregional recurrence (LRR) after adequate treatment of primary breast cancer poses a therapeutic challenge. Advances in the management of breast cancer have led to significant improvements in survival. With this advantage, it is observed that the incidence of LRR has relatively decreased. Systemic involvement should be ruled out in patients presenting with locoregionally recurrent disease, as isolated LRR requires a treatment with curative intent. Salvage mastectomy following ipsilateral breast tumor recurrence is a time-tested treatment option and widely accepted...

PURPOSE: Postmastectomy chest wall radiation therapy has historically used bolus to increase dose at the skin surface. Despite the theoretical benefits of bolus, the clinical implications of locoregional tumor control, cosmesis, and the incidence of radiodermatitis are less well characterized. We hypothesized that treatment in the presence or absence of bolus results in equivalent chest wall recurrence rates, but its presence results in more severe acute dermatologic toxicity. METHODS AND MATERIALS: Locally advanced breast cancer patients undergoing chest wall radiation therapy were retrospectively reviewed from 2005 to 2015 (n = 106; 53 with bolus, 53 without)...

A 62 year-old male with long-standing smoking history presented with hemoptysis. Plain chest x-ray showed abnormal findings proximate to the right pulmonary hilum. Bronchoscopy revealed a fragile exophytic tumor of the right wall of the lower third of the trachea, infiltrating the right main bronchus (75% stenosis) and the right upper lobar bronchus (near total occlusion). Contrast-enhanced chest CT demonstrated a 7.2x4.9 cm tumor contiguous to the above-mentioned structures, mediastinal lymph node pathology, and a vessel coursing inferiorly to the left of the aortic arch and anterior to the left hilum...

Primary benign tumors of trachea are rare. Of them, tracheal leiomyoma, constitutes only 1% of all benign lower respiratory tract tumors. Here, we present a case of tracheal leiomyoma who has been receiving high doses of inhaled corticosteroids and bronchodilators for a year with a misdiagnosis of asthma. As the symptoms did not resolve with an overtreatment, she has been undergone radiologic study to find a possible alternative diagnosis. The chest roentgenogram revealed an opacity in the upper mediastinum...
