PURPOSE The aim of this study was to report the prevalence of postoperative complications and mortality of patients with colorectal cancer when treated by conventional surgery. METHODS Morbidity and mortality following open resection for colorectal cancer were analyzed in 1,846 patients whose clinical, operative, and pathology data were prospectively(More)
BACKGROUND AND OBJECTIVES Recent advancements in the technology of cryosurgery along with the development and refinement of intraoperative ultrasound have led to a feasible alternative for some patients with unresectable hepatic malignancy. This paper reports our first year's experience with cryosurgical ablation of unresectable hepatic malignancies. (More)
It is estimated that the hereditary polyposis and non-polyposis colorectal cancer (CRC) syndromes, which have an autosomal dominant pattern of inheritance, represent less than 10% of the total CRC burden. Thus, more than 90% of all cases of CRC have previously been considered to arise 'sporadically', with no identifiable genetic link. However, recent(More)
PURPOSE The objective of our investigation was to attempt to address the controversial issue concerning index screening and surveillance of relatives of patients with colorectal cancer and to identify those areas of research that should be considered in future studies. METHODS Relevant literature was reviewed concerning the screening of asymptomatic(More)
A simulation model for the analysis of gas-phase trace contaminants in the cabin air of the NASA Space Station Reference Configuration was developed at the NASA Langley Research Center. The model predicts changes in trace contaminant concentrations from both physical and chemical sources an sinks as a function of time. Simulations were performed in which(More)
