Increased cancer incidence in some gallstone diseases, and equivocal effect of cholecystectomy: a long-term analysis of cancer and mortality.
Summary of "Increased cancer incidence in some gallstone diseases, and equivocal effect of cholecystectomy: a long-term analysis of cancer and mortality."
Abstract Background. Our aim was to investigate cancer incidence and the cause of long-term mortality in different gallstone diseases and conditions. Study design. The study population consisted of 2034 subjects: 224 persons diagnosed with asymptomatic gallstones in 1983, 254 patients who underwent cholecystectomy in 1983, and 513 patients with symptomatic uncomplicated gallstones (SGS, n = 337) or acute cholecystitis (AC, n = 176) between 1992 and 1994. One thousand and forty-three people who participated in a population study in 1983 were controls. Results. An overall increased risk of cancer, as well as higher mortality, was found among persons with asymptomatic gallstones compared to controls (HR 1.46, 95%
1.06-2.00 and HR 1.39, 95%
1.08-1.78), whereas patients who underwent cholecystectomy in 1983 showed a slightly higher risk (not significant) for both cancer and death than controls. Among patients with SGS from 1992 to 1994 there was a significantly higher risk of contracting cancer in patients who had undergone surgery (HR = 2.56, 95%
1.13-5.83). For patients with AC, there was no significant difference between surgically treated and non-surgically treated subjects, but there was a higher risk of cancer in all AC compared to SGS patients (HR 2.03, 95%
1.20-3.43). Mortality did not differ significantly between surgically treated and non-surgically treated patients with SGS or AC. Conclusion. Gallstone patients had a greater risk than the general population for developing cancer, but this was dependent on the type of gallstone condition and treatment. The effect of cholecystectomy seemed dubious.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
The effect of GLOBAL WARMING and the resulting increase in world temperatures. The predicted health effects of such long-term climatic change include increased incidence of respiratory, water-borne, and vector-borne diseases.
A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions.

Colorectal Neoplasms, Hereditary Nonpolyposis
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
A synthetic PGE2 analog that has an inhibitory effect on gastric acid secretion, a mucoprotective effect, and a postprandial lowering effect on gastrin. It has been shown to be efficient and safe in the treatment of gastroduodenal ulcers.
