Purpose Neuroendocrine tumors (NETs) are considered rare tumors and can produce a variety of hormones. In this study, we examined the epidemiology of and prognostic factors for NETs, because a thorough examination of neither had previously been performed. Methods The Surveillance, Epidemiology, and End Results (SEER) Program registries were searched to(More)
CONTEXT The standard criteria used to evaluate tumor response, the Response Evaluation Criteria in Solid Tumors (RECIST), were developed to assess tumor shrinkage after cytotoxic chemotherapy and may be limited in assessing response to biologic agents, which have a cytostatic mechanism of action. OBJECTIVE To validate novel tumor response criteria based(More)
INTRODUCTION Actual 5-year survival rates of 10-18% have been reported for patients with resected pancreatic adenocarcinoma (PC), but the use of multimodality therapy was uncommon in these series. We evaluated long-term survival and patterns of recurrence in patients treated for PC with contemporary staging and multimodality therapy. METHODS We analyzed(More)
Major vascular resection performed at the time of pancreaticoduodenectomy (PD) for adenocarcinoma remains controversial. We analyzed all patients who underwent vascular resection (VR) at the time of PD for any histology at a single institution between 1990 and 2002. Preoperative imaging criteria for PD included the absence of tumor extension to the celiac(More)
Purpose We conducted a phase II trial of preoperative gemcitabine and cisplatin chemotherapy in addition to chemoradiation (Gem-Cis-XRT) and pancreaticoduodenectomy (PD) for patients with stage I/II pancreatic adenocarcinoma. Patients and Methods Chemotherapy consisted of gemcitabine (750 mg/m 2) and cisplatin (30 mg/m 2) given every 2 weeks for four doses.(More)
PURPOSE The role of carbohydrate antigen (CA) 19-9 in the evaluation of patients with resectable pancreatic cancer treated with neoadjuvant therapy prior to planned surgical resection is unknown. We evaluated CA 19-9 as a marker of therapeutic response, completion of therapy, and survival in patients enrolled on two recently reported clinical trials. (More)
OBJECTIVE To better understand the impact of a microscopically positive margin (R1) on patterns of disease recurrence and survival after pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma. SUMMARY BACKGROUND DATA A positive resection margin after PD is considered to be a poor prognostic factor, and some have proposed that an R1 margin may be a(More)
BACKGROUND Lung metastases are considered a poor prognostic factor in patients with resectable colorectal liver metastases. STUDY DESIGN We reviewed records of 1,260 consecutive patients with liver-only or liver-plus-lung (L+L) metastases from colorectal cancer who underwent resection with curative intent (1995 to 2009). Survival and prognostic factors(More)
OBJECTIVE Improving the prognostic stratification of unresectable hepatocellular carcinoma (HCC) patients is critically needed. Since patients' survival is closely linked to the severity of the underlying liver disease, and insulin-like growth factor-1 (IGF-1) is produced predominantly in the liver, we hypothesized that IGF-1 may correlate with patients'(More)
Pancreatic adenocarcinoma is the fifth leading cause of cancer-related death in the U.S. In spite of advancements in surgical treatment, nearly 80% of patients thought to have localized pancreatic cancer die of recurrent or metastatic disease when treated with surgery alone. Therefore, efforts to alter the patterns of recurrence and improve survival for(More)
