Fatty liver disease, diabetes and a triglycerides level of above 160 milligrams per deciliter (mg/dl) are three major risk factors for developing liver cancer, and the disease’s progression does not necessarily include chronic hepatitis or cirrhosis, the National Health Research Institutes (NHRI) said yesterday.
Liver cancer has been the second-leading cause of cancer deaths for many years, and about 85 percent of cases have been associated with chronic hepatitis viral infections — primarily chronic hepatitis B or hepatitis C — which usually progress to cirrhosis before developing into liver cancer, it said.
However, as more cases of liver cancer that did not involve chronic hepatitis viral infection were diagnosed, the institute in 2005 teamed up with five medical centers to study the cases to identify other key risk factors of liver cancer, it added.
NHRI investigator and attending physician Huang Shiu-feng (黃秀芬) said the team compared data from 411 liver cancer patients who did not have chronic hepatitis infection with 840 patients who had hepatitis infections, and discovered that risk factors for metabolic syndrome also apply to non-viral causes of liver cancer.
People who are over 60 and have at least two of the three risk factors should regularly undergo liver cancer screenings, Huang said.
The researchers also analyzed liver cancer patients who were not addicted to alcohol and did not have cirrhosis, and found that among people who had at least two of the risk factors in this group, more than 70 percent of the men and more than 90 percent of the women had liver cancer without hepatitis infection, she said.
The findings prove that in addition to commonly known risk factors — chronic hepatitis, alcohol addiction and cirrhosis — the three non-viral risk factors they have identified point at increased risk of developing liver cancer, Huang said.
Since Taiwan follows a universal hepatitis B vaccination policy and as new drugs can cure hepatitis C, the government should raise awareness in patients with fatty liver disease and metabolic syndrome so that they can learn about the increased risks of developing liver cancer and undergo cancer screenings.
Linkou Chang Gung Memorial Hospital’s Liver Cancer Research Center director Yeh Chau-Ting (葉昭廷) said about 60 percent of adults in Taiwan have fatty liver, but those who have fatty liver accompanied by inflammation have a higher risk of developing liver cancer.
The Coast Guard Administration (CGA) and Chunghwa Telecom yesterday confirmed that an international undersea cable near Keelung Harbor had been cut by a Chinese ship, the Shunxin-39, a freighter registered in Cameroon. Chunghwa Telecom said the cable had its own backup equipment, and the incident would not affect telecommunications within Taiwan. The CGA said it dispatched a ship under its first fleet after receiving word of the incident and located the Shunxin-39 7 nautical miles (13km) north of Yehliu (野柳) at about 4:40pm on Friday. The CGA demanded that the Shunxin-39 return to seas closer to Keelung Harbor for investigation over the
An apartment building in New Taipei City’s Sanchong District (三重) collapsed last night after a nearby construction project earlier in the day allegedly caused it to tilt. Shortly after work began at 9am on an ongoing excavation of a construction site on Liuzhang Street (六張街), two neighboring apartment buildings tilted and cracked, leading to exterior tiles peeling off, city officials said. The fire department then dispatched personnel to help evacuate 22 residents from nine households. After the incident, the city government first filled the building at No. 190, which appeared to be more badly affected, with water to stabilize the
DEEPER REVIEW: After receiving 19 hospital reports of suspected food poisoning, the Taipei Department of Health applied for an epidemiological investigation A buffet restaurant in Taipei’s Xinyi District (信義) is to be fined NT$3 million (US$91,233) after it remained opened despite an order to suspend operations following reports that 32 people had been treated for suspected food poisoning, the Taipei Department of Health said yesterday. The health department said it on Tuesday received reports from hospitals of people who had suspected food poisoning symptoms, including nausea, vomiting, stomach pain and diarrhea, after they ate at an INPARADISE (饗饗) branch in Breeze Xinyi on Sunday and Monday. As more than six people who ate at the restaurant sought medical treatment, the department ordered the
Taiwan plans to cull as many as 120,000 invasive green iguanas this year to curb the species’ impact on local farmers, the Ministry of Agriculture said. Chiu Kuo-hao (邱國皓), a section chief in the ministry’s Forestry and Nature Conservation Agency, on Sunday said that green iguanas have been recorded across southern Taiwan and as far north as Taichung. Although there is no reliable data on the species’ total population in the country, it has been estimated to be about 200,000, he said. Chiu said about 70,000 iguanas were culled last year, including about 45,000 in Pingtung County, 12,000 in Tainan, 9,900 in
