The flowchart in figure 2.1 is a product of collaboration between C. Acknowledgments Consensus, as a decisionmaking process, has been developing for centuries. Many people , in diverse communities, have contributed to this development. From them, we have borrowed generously and adapted freely.

The Wet Chemistry Laboratory on the Phoenix Mars Lander performed aqueous chemical analyses of martian soil from the polygon-patterned northern plains of the Vastitas Borealis. The solutions contained approximately 10 mM of dissolved salts with 0.4 to 0.6% perchlorate (ClO4) by mass leached from each sample. The remaining anions included small(More)
PURPOSE CA 19-9 is an important tumor marker in patients with pancreatic adenocarcinoma. A secondary end point of Radiation Therapy Oncology Group trial 9704 was prospective evaluation of the ability of postresectional CA 19-9 to predict survival. METHODS CA 19-9 expression was analyzed as a dichotomized variable (< 180 v > or = 180) or (< or = 90 v >(More)
The NCCN Guidelines for Pancreatic Adenocarcinoma discuss the diagnosis and management of adenocarcinomas of the exocrine pancreas and are intended to assist with clinical decision-making. These NCCN Guidelines Insights summarize major discussion points from the 2014 NCCN Pancreatic Adenocarcinoma Panel meeting. The panel discussion focused mainly on the(More)
CONTEXT Among patients with locally advanced metastatic pancreatic adenocarcinoma, gemcitabine has been shown to improve outcomes compared with fluorouracil. OBJECTIVE To determine if the addition of gemcitabine to adjuvant fluorouracil chemoradiation (chemotherapy plus radiation) improves survival for patients with resected pancreatic adenocarcinoma.

BACKGROUND Imatinib inhibits the KIT and PDGFR tyrosine kinases, resulting in its notable antitumor activity in gastrointestinal stromal tumor (GIST). We previously reported the early results of a multi-institutional prospective trial (RTOG 0132) using neoadjuvant/adjuvant imatinib either in primary resectable GIST or as a planned preoperative cytoreduction(More)
Survival after curative resection for pancreatic adenocarcinoma remains poor; an important prognostic factor is lymph node (LN) status. Recent reports have established the number of LN examined as a separate prognostic factor in many malignancies. We retrospectively reviewed the charts of 128 patients undergoing pancreaticoduodenectomy (PD) for pancreatic(More)
Many pancreatic cancer surgeons have been slow to adopt minimally invasive pancreatic surgery (MIPS) due a lack of formalized minimally invasive training and the perceived difficulty in dissecting pancreatic tumors and tissue away from the superior mesenteric vessels and consequent concerns for adequacy of oncologic margins and lymph node retrieval. A(More)
PURPOSE To evaluate potential prognostic factors in the treatment of extremity soft tissue sarcomas that may influence local control, distant metastases, and overall survival. METHODS AND MATERIALS Sixty-seven patients with extremity soft tissue sarcomas were treated with curative intent by limb-sparing surgery and postoperative radiation therapy at the(More)
Long-term therapy of oncology patients has been facilitated by permanent indwelling central venous catheters, but catheter-related infections remain a serious complication of their use. Using a retrospective matched cohort design, we compared the risk of catheter-related infection in 47 adult solid tumor patients with right atrial Hickman catheters and 94(More)
