OBJECTIVES: Metabolic syndrome is an important etiologic factor in the development of certain types of cancers. The economic cost of the treatment of cancer has been steadily increasing. We therefore estimated the economic burden of cancers attributable to metabolic syndrome in Korea. METHODS: We reviewed metabolic syndrome-related cancers and relative risk and then calculated population attributable fractions. We analyzed insurance claims data for metabolic syndrome-related cancers in 2012 in order to estimate the direct costs associated with these cancers, including hospitalization, outpatient visits, transportation costs, and caregivers' costs as well as indirect costs such as loss of productivity due to cancer treatment and premature death. RESULTS: In 2012, 18 070 patients in Korea had cancers attributable to metabolic syndrome. The economic burden was USD 199.8 million and the direct and indirect costs were USD 124.5 million and USD 75.3 million, respectively. CONCLUSIONS: We estimated the economic burden of cancers attributable to metabolic syndrome in Korea and the efforts are necessary to reduce this burden.

OBJECTIVETo study the cost-effectiveness, benefit and utility of infant hepatitis B vaccination in Shanghai from 1992 to 2001.

METHODSTo calculate the cost of hepatitis B vaccination by cost analysis method. Both the numbers of persons with HBsAg positive and patient with hepatitis B, cirrhosis and liver cancer decreased as the index of direct effect. To study the sick-time and the cost of treating hepatitis B, cirrhosis and liver cancer patients, a face to face questionnaire was used and quasi method was adopted to understand the effect of cure and the course of hepatitis B. The cost benefit analysis method was also used to calculate the cost benefit of HBV vaccine. The disability adjusted life years (DALY) was regarded as an index of utility to measure the disease burden.

RESULTSInput of 501,129.49 Yuan might have the result of reducing one liver cancer patient, ten cirrhosis patients, one hundred chronic hepatitis B patients and one thousand HBsAg positive people. The cost of hepatitis B vaccination was 0.24 hundred million Yuan during the past ten years in Shanghai, which had obtained the total benefit value of 41.22 hundred million Yuan, with a cost benefit ratio of 1:172 Yuan. It was estimated that the total disease burden of hepatitis B, cirrhosis and liver cancer patients was 59,762.55 DALY in order to reduce one DALY loss cost of 402.50 Yuan.

CONCLUSIONHBV vaccine inoculation in infants seemed to be a low-cost input and high-effect output strategy.

An understanding of the characteristics of occupational lung cancer is important to establish policies that prevent carcinogen exposure and to compensate workers exposed to lung carcinogens. This study analyzed the characteristics of occupational lung cancers in workers who were compensated under the Industrial Accident Compensation Insurance Law between 1994 and 2011. A total of 179 occupational lung cancers were compensated. The main carcinogenic exposure was asbestos, followed by crystalline silica and hexavalent chromium. The mean exposure duration and latency were 19.8 and 23.2 yr. The most common industry was manufacturing, followed by construction and transportation. The most common occupation was maintenance and repair, followed by foundry work, welding, painting, and spinning or weaving. Although asbestos was predominant carcinogen, the proportion of these cases was relatively low compared to other developed countries. Proper surveillance system is needed to monitor occupational lung cancer and improve prevention measures.

Three patients of pseudomyxoma peritonei who were diagnozed by transumbilical endoscopic surgery (TUES) were reviewed retrospectively from September 2014 to November 2014. Three cases of ascites patients underwent TUES were diagnozed as pseudomyxoma peritonei. All operations were successful. No open surgery or laparoscopic surgery was required. The mean operative time was (45±16) min; the mean intraoperative blood loss was 510 mL; the mean hospital stay time was 3 days. During the follow up of 911 months, no obvious scar was observed. Cosmetic results appear to be excellent. All patients were treated with intraperitoneal hyperthermia and chemotherapy. The survival rate was 100%. As a novel scarless endoscopic invasive abdominal surgery, TUES has high clinical value with the advantages such as small trauma, no scars, small risk and low cost in the diagnosis of unexplained ascites.
