Prostate Cancer Diagnosis in Taiwan Cut to One Month with New Micro-Ultrasound Tech

National Taiwan University Hospital (NTUH) is revolutionizing prostate cancer diagnosis with the adoption of high-resolution micro-ultrasound technology. This advanced imaging system promises to drastically cut down the waiting time for patients, a process that traditionally could take over six months from initial screening to definitive diagnosis.

The new micro-ultrasound technology allows for real-time identification of suspicious lesions within the prostate gland. This precision enables targeted biopsies, significantly improving diagnostic accuracy and speed. NTUH reports that the entire diagnostic process, including the biopsy, can now be completed in as little as one month, a substantial improvement over the previous six-month or longer waiting periods. This expedited diagnosis is crucial for enabling patients to commence treatment sooner.

The resolution can reach 70 micrometers, equivalent to the diameter of a hair, which greatly enhances the ability to observe subtle changes in prostate structures and improves the accuracy of cancer lesion identification.

Two patients, Mr. Huang and Mr. Lin, both 78 years old, shared their experiences with the new technology. Mr. Huang's elevated PSA levels and urinary symptoms led to a diagnosis of localized prostate cancer within two weeks of a targeted biopsy guided by micro-ultrasound. Mr. Lin, initially undergoing checks for stomach cancer, was found to have elevated PSA and bone scan abnormalities. Micro-ultrasound pinpointed metastatic prostate cancer, allowing him to access new government-subsidized medication, which has since lowered his PSA levels significantly.

While the benefits of early and accurate diagnosis are clear, it is important to note that the micro-ultrasound examination and subsequent targeted biopsy are not covered by Taiwan's National Health Insurance and require out-of-pocket payment. Despite this, the hospital plans to further streamline the process with a "one-stop examination and biopsy" service to further reduce patient waiting times. The technology, utilizing a 29MHz high-frequency probe, offers a resolution of up to 70 micrometers, comparable to the diameter of a human hair, greatly enhancing the visualization of subtle prostate tissue changes.

Through micro-ultrasound, the diagnosis can be completed in as little as one month, allowing treatment to begin within two to three months.
