BACKGROUND Colonoscopic localization of rectal and rectosigmoid tumors may be inaccurate. Rigid proctosigmoidoscopy has been suggested as an adjunctive technique to accurately localize rectal tumors as it may alter treatment options. METHODS A retrospective review was performed of patients with rectal and rectosigmoid cancer from 2001 to 2006. Patients(More)
Pancreatic resections are some of the most technically challenging operations performed by surgeons, and post-operative pancreatic fistula (POPF) are not uncommon, developing in approximately 13% of pancreaticoduodenectomies and 30% of distal pancreatectomies. Multiple trials of various operative techniques in the creation of the pancreatic ductal(More)
Colorectal cancer (CRC) is a leading worldwide health concern that is responsible for thousands of deaths each year. The primary source of mortality for patients with CRC is the development and subsequent progression of metastatic disease. The most common site for distant metastatic disease is the liver. Although patients with metastatic disease to the(More)
The annual incidence of inflammatory breast cancer (IBC) in the United States reportedly increased during the last quarter of the twentieth century. We investigated whether that increase has continued into the twenty-first century. We queried the Surveillance Epidemiology and End Results database for all cases of IBC in women age 20 and older between 1992(More)
The benefit of adjuvant radiotherapy (RT) in elderly breast cancer patients is debatable. The purpose of this study was to evaluate trends in RT rates after breast-conserving surgery. Breast cancer patients ≥70 years treated from 2000 to 2009 were identified using the Surveillance, Epidemiology, and End Results (SEER) database. Patients were estrogen(More)
Melanoma-associated chondroitin sulfate proteoglycan (MCSP; also called HMW-MAA, CSPG4, NG2, MSK16, MCSPG, MEL-CSPG, or gp240) is a well characterized melanoma cell-surface antigen. In this study, a new bispecific T-cell engaging (BiTE) antibody that binds to MCSP and human CD3 (MCSP-BiTE) was tested for its cytotoxic activity against human melanoma cell(More)
Although breast cancer frequently metastasizes to the bones and brain, rarely breast cancer patients may develop isolated liver metastasis. There is increasing data that anti-HER2 targeted therapy in conjunction with systemic chemotherapy may lead to increased rates of pathologic complete response in the primary breast cancer. However, little is known about(More)
Current concepts in the management of hepatic metastases have changed dramatically over the past two decades. Multidisciplinary therapies including chemotherapy, surgery, and regional therapy have alone and in combination significantly improved the survival of patients with metastatic colorectal cancer. Conditions that were previously considered hopeless(More)
AIM To predict node-positive disease in colon cancer using computed tomography (CT). METHODS American Joint Committee on Cancer stage I-III colon cancer patients who underwent curavtive-intent colectomy between 2007-2010 were identified at a single comprehensive cancer center. All patients had preoperative CT scans with original radiology reports from(More)
Gastrointestinal stromal tumors (GISTs) in adolescence are far less common than adult GISTs and have varied GIST genotypes that present diagnostic and therapeutic challenges. Here, we discuss a 21-year-old male with diagnosis of unresectable, imatinib-resistant GIST. At initial evaluation, a neoadjuvant treatment approach was recommended. As such, the(More)
