Cancer diagnostics and treatment may become more effective in the near future with the help of isotope applications, the Institute of Nuclear Energy Research's Radiation Application Technology Center (RATC) said yesterday at a press conference.
"Cancer has been Taiwan's leading cause of death for more than 25 years, but by developing new technologies the RATC can help the medical sector reduce incidents of late diagnosis, as well as increase the effects of existing drugs," the center's isotope application division associate scientist Luo Tsai-yueh (羅彩月) told reporters.
So far the center has achieved preliminary results for both pharmaceuticals and medical equipment such as an early-stage breast cancer scanner set to hit the market by the end of the year.
"Breast cancer is one of the leading causes of female mortality in Taiwan, but most of the deaths are due to late discovery of the disease," Luo said, adding that first-stage breast cancer prognosis has a near-100 percent survival rate.
"The scanner images with FDG, which is a glucose analog that would be consumed by glucose-hungry cells such as brain or cancer cells," Luo said.
With the fluorine in the FDG molecule emitting radioactive traces, the substance can be injected into the body to show the distribution of cancer cells on a positron emission tomography (PET) scanner, even at their early stage, Luo said.
The new breast cancer scanner has two other strong appeals compared with its predecessors, Luo said.
"With Taiwanese culture in mind, the scanner is compact and mobile so that it can tour community centers and help women who are too shy to visit hospitals to get regular checkups," Luo said.
"Also, the machines are significantly cheaper than traditional models. We are not targeting the VIP market. We want everyone to be able to reap the benefits," she said.
The center is also working on target therapy drugs for cancer, conjugating monoclonal antibodies with therapeutic radioisotopes, Luo said.
"Currently monoclonal antibodies are one of the most commonly used drugs to battle cancer. By using radioisotopes, the drug works more effectively because the body's natural antibodies are not combating the tumor cells on their own. Radiation emitted by the radioisotopes carried by the compound also have curing effects," she said.
The compound had achieved preliminary success in rats and will enter clinical trials soon, she said.
An increase in Taiwanese boats using China-made automatic identification systems (AIS) could confuse coast guards patrolling waters off Taiwan’s southwest coast and become a loophole in the national security system, sources familiar with the matter said yesterday. Taiwan ADIZ, a Facebook page created by enthusiasts who monitor Chinese military activities in airspace and waters off Taiwan’s southwest coast, on Saturday identified what seemed to be a Chinese cargo container ship near Penghu County. The Coast Guard Administration went to the location after receiving the tip and found that it was a Taiwanese yacht, which had a Chinese AIS installed. Similar instances had also
GOOD DIPLOMACY: The KMT has maintained close contact with representative offices in Taiwan and had extended an invitation to Russia as well, the KMT said The Chinese Nationalist Party (KMT) would “appropriately handle” the fallout from an invitation it had extended to Russia’s representative to Taipei to attend its international banquet last month, KMT Chairman Eric Chu (朱立倫) said yesterday. US and EU representatives in Taiwan boycotted the event, and only later agreed to attend after the KMT rescinded its invitation to the Russian representative. The KMT has maintained long-term close contact with all representative offices and embassies in Taiwan, and had extended the invitation as a practice of good diplomacy, Chu said. “Some EU countries have expressed their opinions of Russia, and the KMT respects that,” he
VIGILANCE: The military is paying close attention to actions that might damage peace and stability in the region, the deputy minister of national defense said The People’s Republic of China (PRC) might consider initiating a hack on Taiwanese networks on May 20, the day of the inauguration ceremony of president-elect William Lai (賴清德), sources familiar with cross-strait issues said. While US Secretary of State Anthony Blinken’s statement of the US expectation “that all sides will conduct themselves with restraint and prudence in the period ahead” would prevent military actions by China, Beijing could still try to sabotage Taiwan’s inauguration ceremony, the source said. China might gain access to the video screens outside of the Presidential Office Building and display embarrassing messages from Beijing, such as congratulating Lai
Four China Coast Guard ships briefly sailed through prohibited waters near Kinmen County, Taipei said, urging Beijing to stop actions that endanger navigation safety. The Chinese ships entered waters south of Kinmen, 5km from the Chinese city of Xiamen, at about 3:30pm on Monday, the Coast Guard Administration said in a statement later the same day. The ships “sailed out of our prohibited and restricted waters” about an hour later, the agency said, urging Beijing to immediately stop “behavior that endangers navigation safety.” Ministry of National Defense spokesman Sun Li-fang (孫立方) yesterday told reporters that Taiwan would boost support to the Coast Guard
