The ability to visualize biochemical processes in tumor tissues by PET and correlate these findings with anatomic imaging such as CT and MRI gives new insight into the metabolic and physiologic aspects of the tumor tissue. This may permit discrimination between recurrent colorectal carcinoma and some benign lesions. The potential for its use in pharmacology(More)
Our purposes were to explore the epidemiology of metastases to skeletal muscle and their detection on fused positron emission tomography and computed tomography. We evaluated the epidemiology of skeletal muscle metastases in the literature and among cases from our hospital and studied the prevalence and appearance of skeletal muscle metastases among 433(More)
Carcinoma of unknown primary (CUP), which accounts for about 3-5% of all new cancers, is a challenging heterogeneous entity with an unmet research need. Traditionally, CUP has been managed with broad-spectrum chemotherapy, but with the increasing availability of sophisticated diagnostic techniques and the emergence of new treatments that have been shown to(More)
OBJECTIVE To assess the use of donor pigs with cellular chimerism for prevention of acute rejection with modest immune suppression. The clinical use of pig organ xenografts is currently precluded by severe acute rejection, which resists standard immune suppression. SUMMARY BACKGROUND DATA For long-term survival of pig organ xenografts, immune suppression(More)
OBJECTIVES The chronic effects of renal radiofrequency ablation are unknown. Herein, we investigate the anatomic and physiologic sequelae of laparoscopic and percutaneous renal radiofrequency ablation in acute and chronic porcine models. METHODS Our study comprised two phases-an acute phase and a chronic phase. In the acute phase, bilateral laparoscopic(More)
BACKGROUND The purpose of this study was to determine the overall survival (OS) of patients with resectable gastric cancer treated with preoperative chemoradiation therapy and gastrectomy. STUDY DESIGN The medical records of patients with gastric adenocarcinoma presenting to our institution (January 1995 to August 2012) were reviewed to identify patients(More)
PURPOSE The purposes of this study were to determine whether available laparoscopic stapling devices could be used to interrupt the diseased human aorta, and to develop a videoscopic technique for retroperitoneal exposure and control of the infrarenal aorta in pigs. Our long-term goal is to develop a minimally invasive approach to the treatment of abdominal(More)
BACKGROUND The purpose of this study was to determine the survival of patients with metastatic gastric cancer treated with surgery. METHODS We reviewed the medical records of 7,404 patients with gastric or gastroesophageal cancer seen from January 1995 to August 2012 at MD Anderson Cancer Center and identified patients with stage IV disease treated with(More)
Complete cytoreduction with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) has been shown to improve survival in patients with low-grade mucinous adenocarcinoma (LGMA). However, incomplete cytoreduction exposes patients to significant morbidity without a similar survival benefit. Preoperative assessment of the ability to achieve CRS is therefore a(More)
This study aimed to determine whether postoperative morbidity and mortality rates increased after preoperative chemoradiation in patients who underwent gastrectomy. The medical records of 7404 patients with gastric or gastroesophageal cancer seen from January 1995 to August 2012 were reviewed to identify patients who underwent gastrectomy. χ 2 and logistic(More)
