The records of 256 patients with nasopharyngeal carcinoma have been reviewed to determine the incidence and location of distant metastases. Sixty-three patients underwent autopsy. The incidence of distant metastases was 36% overall, and 51% in the autopsy patients. Bones, distant lymphnodes, liver, and lungs were the most common sites of distant metastases. Liver was the most common site in the autopsy patients. Compared to other major histological subtypes, undifferentiated carcinoma had the highest incidence of bone but lowest incidence of lung metastases. There was a strong correlation between advanced locoregional disease and distant metastases. Of those patients who developed distant metastases, 98% were discovered within 3 years or earlier. Thorough evaluation of the above organs/systems is indicated at the time of initial staging work-up and at follow-up, specifically for patients with advanced locoregional disease. A literature review of distant metastases in nasopharyngeal carcinoma is presented.
Emergency cholecystectomy is less costly and more effective than delayed cholecystectomy. This approach is likely to be beneficial to patients in terms of improved health outcomes and to the healthcare provider owing to the reduced costs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
