Esophageal cancer remains a malignancy with high morbidity and mortality despite improvements to diagnosis, staging, chemotherapy, radiation, and surgery. Neoadjuvant therapy (NT) may improve oncologic outcome in many patients, however the degree to which patients benefit remains unclear. We examined the relationship between pathologic response to NT and(More)
Incidences of esophageal cancer and obesity are both rising in the United States. The aim of this study was to determine the influence of elevated body mass index on outcomes after esophagectomy for cancer. Overall and disease-free survivals in obese (BMI ≥ 30), overweight (BMI 25–29), and normal-weight (BMI 20–24) patients undergoing esophagectomy(More)
BACKGROUND Several trials have been conducted to determine the feasibility of preoperative radiotherapy (RT) for gastric cancer. However, the absolute benefit from radiotherapy remains to be defined. In this study, the authors examined the use of preoperative RT (Pre-RT) and postoperative RT (PORT) in patients with gastric cancer from the Surveillance,(More)
PURPOSE Stereotactic body radiation therapy (SBRT) provides high rates of local control (LC) and margin-negative (R0) resections for locally advanced pancreatic cancer (LAPC) and borderline resectable pancreatic cancer (BRPC), respectively, with minimal toxicity. METHODS AND MATERIALS A single-institution retrospective review was performed for patients(More)
PURPOSE We compared our institutional experience using 3D conformal radiation therapy (3DCRT) vs. IMRT (intensity-modulated radiation therapy) for anal cancer. METHODS We performed a single-institution retrospective review of all patients with squamous cell carcinoma anal cancer treated from September 2000 through September 2011, using definitive(More)
This study seeks to determine the effects of postoperative radiation therapy and lymphadenectomy on survival in esophageal cancer. An analysis of patients with surgically resected esophageal cancer from the SEER database between 2004 and 2008 was performed to determine association of adjuvant radiation and lymph node dissection on survival. Survival curves(More)
The expansion of robotic-assisted surgery is occurring quickly, though little is generally known about the “learning curve” for the technology with utilization for complex esophageal procedures. The purpose of this study is to define the learning curve for robotic-assisted esophagogastrectomy with respect to operative time, conversion rates, and patient(More)
PURPOSE TNFerade biologic is a novel means of delivering tumor necrosis factor alpha to tumor cells by gene transfer. We herein report final results of the largest randomized phase III trial performed to date among patients with locally advanced pancreatic cancer (LAPC) and the first to test gene transfer against this malignancy. PATIENTS AND METHODS In(More)
Stereotactic radiation approaches are gaining more popularity for the treatment of intracranial as well as extracranial tumors in organs such as the liver and lung. Technology, rather than biology, is driving the rapid adoption of stereotactic body radiation therapy (SBRT), also known as stereotactic ablative radiotherapy (SABR), in the clinic due to(More)
OBJECTIVES To determine the outcomes of postoperative radiation therapy on survival in gastric cancer. METHODS An analysis of patients with surgically resected and nonmetastatic gastric cancer from the Surveillance, Epidemiology, and End Results database from 1990 to 2003 was carried out. Survival curves were calculated according to the Kaplan-Meier(More)
