Background: The increasing use of computed tomography (CT) scans in the evaluation of trauma patients has led to increased detection of incidental radiologic findings. Incidental findings (IFs) of the abdominal viscera are among the most commonly discovered lesions and can carry a risk of malignancy. Despite this, patient notification regarding these findings is often inadequate.
View Article and Find Full Text PDFBackground: A novel data warehouse based on automated retrieval from an institutional health care information system (HIS) was made available to be compared with a traditional prospectively maintained surgical database.
Methods: A newly established institutional data warehouse at a single-institution academic medical center autopopulated by HIS was queried for International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) diagnosis codes for pancreatic neoplasm. Patients with ICD-9-CM diagnosis codes for pancreatic neoplasm were captured.
Background: Patients are increasingly confronted with systems for rating hospitals. However, the correlations between publicized ratings and actual outcomes after pancreatectomy are unknown.
Methods: The Massachusetts Division of Health Care Finance and Policy Hospital Inpatient Discharge Database was queried to identify pancreatic cancer resections carried out during 2005-2009.
Background: Although debate continues on US healthcare and insurance reform, data are lacking on the effect of insurance on community-level cancer outcomes. Therefore, the objective of the present study was to examine the association of insurance and cancer outcomes.
Materials And Methods: The US Census Bureau Current Population Survey, Small Area Health Insurance Estimates (2000) were used for the rates of uninsurance.
Purpose: Tumor registry (TR) data are becoming more prominently cited in research through increased use of the National Cancer Database. We aimed to establish the accuracy of TR data by comparing them with physician medical record review (MD review) using pancreatic neuroendocrine tumors (NETs) as an example.
Methods: For MD review, the health information system of an academic medical center was queried for patients with pancreatic International Classification of Diseases, ninth revision (ICD-9), codes from January 2000 to August 2008.
Potential benefit of resection for stage IV gastric cancer: a national survey.
J Gastrointest Surg
November 2010
Introduction: Controversy exists as to whether patients with stage IV gastric cancer should undergo surgical resection. We examined the association of gastrectomy with survival in this population.
Methods: Stage IV gastric cancer diagnoses were identified using the SEER database (1988-2005).
Background: Although resection of pancreatic neuroendocrine tumors (PNETs) has a demonstrated survival advantage, further evaluation of the overall morbidity of these procedures is needed. Our objective was to examine a composite outcome of major postoperative complications, including in-hospital mortality.
Materials And Methods: The Nationwide Inpatient Sample (NIS), 1998-2006, was used to identify all patients with a diagnosis of PNET who had undergone pancreatectomy.
Background: Recent studies have shown adjuvant therapy improves outcomes from pancreatic cancer (PC). This study investigates receipt and timing of PC treatments, and association with outcomes.
Methods: The analysis cohort consisted of patients with newly-diagnosed PC at a single institution over 5 years.
Background: The benefit of adjuvant radiotherapy (RT) for resected pancreatic adenocarcinoma remains controversial after randomized clinical trials. In this national-level US study, a propensity score (conditional probability of receiving RT) was used to adjust for potential confounding in nonrandomized designs from treatment group differences.
Methods: Patients were identified from the Surveillance, Epidemiology, and End Results (SEER) registry (1988-2005 dataset).
Objective: To evaluate the effect of surgical resection and radiotherapy (RT) in retroperitoneal or abdominal sarcoma.
Design: Retrospective cohort.
Setting: Surveillance, Epidemiology, and End Results, 1988-2005.
Background: Adrenalectomy remains the definitive therapy for most adrenal neoplasms. Introduced in the 1990s, laparoscopic adrenalectomy is reported to have lower associated morbidity and mortality. This study aimed to evaluate national adrenalectomy trends, including major postoperative complications and perioperative mortality.
View Article and Find Full Text PDFBackground: Pancreatectomy for cancer continues to have substantial perioperative risk, and the factors affecting mortality are ill defined. An integer-based risk score based on national data might help clarify the risk of in-hospital mortality in patients undergoing pancreatic resection.
Methods: Records with the diagnosis of pancreatic cancer were queried from the Nationwide Inpatient Sample for 1998-2006.
Background: : Pancreatic adenocarcinoma is a deadly disease; however, recent studies have suggested improved outcomes in patients with locoregional cancer. Progress was evaluated at a national level in resected patients, as measured by the proportion who received guideline-directed treatment and trends in survival.
Methods: : The linked Surveillance, Epidemiology, and End Results and Medicare databases were queried to identify resections for pancreatic adenocarcinoma performed between 1991 and 2002.
Background: Because of the malignant potential, resection has been recommended for some intraductal papillary mucinous neoplasms (IPMN). We hypothesize that a large cancer database could be used to evaluate national resection rates and survival for malignant IPMN.
Materials And Methods: Using the Surveillance Epidemiology and End Results (SEER) database, 1988-2003, cases of malignant IPMN were identified using histology codes.
Introduction: Reported morbidity varies widely for laparoscopic cholecystectomy (LC). A reliable method to determine complication risk may be useful to optimize care. We developed an integer-based risk score to determine the likelihood of major complications following LC.
View Article and Find Full Text PDFBackground: Blacks have a higher incidence of pancreatic adenocarcinoma and worse outcomes compared to whites. Identifying barriers in pancreatic cancer care may explain survival differences and provide areas for intervention.
Methods: Pancreatic adenocarcinoma patients were identified in the Surveillance, Epidemiology, and End Results Registry (1991-2002).
Background: Blacks are affected disproportionately by pancreatic adenocarcinoma and have been linked with poor survival. Surgical resection remains the only potential curative option. If surgical disparities exist, then they may provide insight into outcome discrepancies.
View Article and Find Full Text PDFBackground: Although surgical resection is generally recommended for patients with localized pancreatic neuroendocrine tumors (PNETs), the impact of resection on overall survival is unknown. The authors investigated the survival advantage of pancreatic resection using a national database.
Methods: This is a retrospective survival analysis of patients with PNETs from the Surveillance, Epidemiology, and End Results database (1988-2002).
