Researchers at the National Health Research Institutes (NHRI) have developed a system to treat breast cancer that reduces skin burns, eliminates scarring and causes few side effects, the institute said on Monday.
The system consists of a ring-shaped high-intensity focused ultrasound (HIFU) transducer, a commercial power amplifier, a mechanical positioner and graphical user-interface control software, it said.
HIFU ablation is a non-invasive therapeutic technique that uses non-ionizing ultrasonic waves to heat or ablate tissues, such as tumors, and requires no surgery.
It has emerged in the past few years as a non-invasive treatment for breast cancer.
Chen Gin-shin (陳景欣), who heads a research team at the Institute of Biomedical Engineering and Nanomedicine, said the system was developed to overcome several problems associated with conventional HIFU procedures, such as skin burns.
The new system reduces treatment time and improves high-precision ablation under imaging guidance, and the ring-shaped transducer can minimize damage to chest tissue, the lungs and the heart, Chen said.
The ablation of a 5cm tumor can take 30 minutes using the new system, he added.
The removal of a 3cm to 5cm cancerous tumor using a conventional HIFU transducer can take up to two hours, he said.
Breast cancer is the most common cancer type among women in Taiwan, the NHRI said, adding that clinical treatment comprises surgery, radiotherapy, chemotherapy, hormone therapy, targeted therapy and combination therapy.
However, women with breast cancer can experience complications, a high re-excision rate, and possible side effects from radiotherapy and chemotherapy, while some need breast reconstruction after tissue removal, it said.
Although the HIFU procedure has become popular among patients, about 30 to 40 percent of them experience musculoskeletal or heart burns, the NHRI said.
NHRI president Liang Kung-yee (梁賡義) said it is seeking partners for technical transfer so that the prototype system could reach the mass market.
The NHRI’s research findings have been published by the IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control.
921 EARTHQUAKE: The magnitude 7.3 quake left 2,456 people dead and 10,718 injured, while 53,661 houses were fully destroyed and 53,024 houses damaged The Central Weather Bureau yesterday received about 50,000 views on Facebook after it posted the data that it collected on Sept. 21, 1999, when the nation was devastated by a magnitude 7.3 earthquake. The data showed that the 921 Earthquake hit the nation at 1:47am, with the epicenter being 7km southwest of the bureau’s quake detection center in Nantou County’s Yuchi Township (魚池) at a depth of 8km. The quake left 2,456 people dead and 10,718 injured, while 53,661 houses were fully destroyed and 53,024 houses damaged, with the cost of the damage estimated at NT$300 billion (US$10.8 billion at the current
British newspaper The Mail on Sunday reported that Prince Charles met with Bruno Wang (汪家興), a Taiwanese fugitive who describes himself as a Chinese philanthropist and donated ￡500,000 (US$683,522) to the prince’s charity, the Prince’s Foundation. The newspaper reported that Wang is wanted in Taiwan on charges related to money laundering and being a fugitive from justice, allegations he denies, and drew comparisons between Wang and the Russian banker Dmitry Leus. Investigation and cooperation with foreign authorities have found that Bruno Wang’s father, Andrew Wang (汪傳浦), had stashed proceeds from a scandal involving the procurement of Lafayette frigates in 61 bank accounts,
AT ODDS: The KMT called on the government to seek bilateral dialogue with Beijing to resolve the issue that led to the ban on custard apple and wax apple imports Democratic Progressive Party (DPP) officials and lawmakers yesterday condemned China’s sudden ban on imports of custard apples and wax apples from Taiwan as “obvious political retaliation,” while the opposition called for a scientific investigation into Beijing’s claim to have found pests in imports of the fruits. China earlier yesterday announced a ban on the importation of the two fruits from today, citing repeated discoveries of Planococcus minor, a type of mealybug. The announcement follows a similar ban on Taiwanese pineapples imposed in February. At least Beijing gave a few days’ notice when it banned pineapple imports, an unnamed government official said yesterday. This time
BY OTHER MEANS: China could see CPTPP membership as a means of circumventing trade restrictions imposed by the US, amid an ongoing trade dispute between them The US could invoke a clause in its trade agreement with Canada and Mexico to block China’s application to join the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), a government official said yesterday. Under Article 32.10 of the Exceptions and General Provisions of the United States-Mexico-Canada Agreement (USMCA), if either Canada or Mexico enter a free-trade agreement with a nonmarket economy — such as China — the US could withdraw from the agreement. “If that clause applies to multilateral free-trade agreements such as the CPTPP — which Mexico and Canada are members of — that might be cause for the two
