Checking PSA levels too soon after prostate cancer surgery can lead to overtreatment
2025-03-13
(Press-News.org) After surgical removal of the prostate to treat prostate cancer, clinicians monitor Prostate Specific Antigen (PSA) levels. Persistently elevated PSA levels indicate residual cancer and are linked to worse outcomes. But in a paper published in JAMA Oncology, Mass General Brigham researchers found that the current standard monitoring time of one-and-a-half to two months following surgery is too short to accurately identify recurrence and inform treatment decisions. Rather, PSA levels should be measured for at least three months to avoid overtreatment.
“Checking the PSA level too soon can lead clinicians to mislabel a patient as having recurred and prompt referral to radiation and medical oncologists to initiate salvage radiation and hormonal therapy,” said senior author Anthony D’Amico, MD, PhD, chief of Genitourinary Radiation Oncology at Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system. “It can take longer than three months for many patients who have PSA levels > 20 prior to surgery to completely clear the PSA from their bloodstream.”
“The clinical significance of these findings is that they highlight the need to monitor PSA after surgery for longer than the commonly practiced one-and-a-half to two months before concluding that PSA levels are persistent and initiating additional therapy,” said D’Amico.

Cancer continues to be a leading cause of mortality worldwide, highlighting the urgent need to develop more advanced, efficient, and early detection methods. Addressing this critical need, City University of Hong Kong (CityUHK) is leading a groundbreaking research project aimed at developing an innovative technology platform for early detection of cancer and personalised treatment. The project aims specifically to enhance the detection of circulating tumor cells (CTCs), paving the way for significant advancements in cancer diagnosis and care. This is one of the first batch of projects that has secured funding by the RAISe+ Scheme.

University of Virginia School of Medicine scientists have discovered how severe COVID-19 can destroy immune cells’ ability to repair the lungs, helping explain the lingering effects of long COVID. The findings suggest a new treatment approach for long COVID as well as other conditions, both short-term and chronic, caused by respiratory infections such as the flu.
Led by UVA’s Jie Sun, PhD, the researchers found that severe viral infections including COVID-19 and the flu can gravely damage a key organelle inside immune cells called macrophages. Macrophages direct lung repair after tissue damage, but their ability to do so is crippled ...

As urbanization surges and climate change intensifies, cities worldwide are facing an increasing number of coupled risks. A recent paper published in Engineering offers fresh insights into understanding and managing these risks.
The complexity of coupled risks in cities, which result from the compounded effects of interacting uncertainties across multiple interdependent objectives, is a major concern. A disruption in one urban subsystem can trigger a chain reaction, affecting other subsystems and leading to unforeseen consequences. For example, the extreme rainfall not only damaged infrastructure ...

Researchers have demonstrated an integrated optical link on a silicon wafer that exhibits high-speed data transmission with very low power consumption. The advance, which was possible because of new low-energy membrane photonic devices made from indium phosphide, could help improve the power efficiency of integrated photonic circuit boards and chip packages without compromising speed.
Tatsurou Hiraki from NTT Corporation in Japan will present this research at OFC, the premier global event for optical communications and networking, which will take place 30 March – 03 April 2025 at the Moscone Center ...

OAK BROOK, Ill. – Denoised ultra-low dose CT can effectively diagnose pneumonia in immunocompromised patients using only 2% of the radiation dose of standard CT, according to a study published today in Radiology: Cardiothoracic Imaging, a journal of the Radiological Society of North America (RSNA).
“For patients with weakened immune systems, lung infections can be life threatening,” said lead study author Maximiliano Klug, M.D., a radiologist in the division of diagnostic imaging at the Sheba Medical Center in Ramat Gan, Israel. “CT scans are the gold standard for detecting pneumonia, but repeated ...

Among older adults in Spain, hospitalisation rates from respiratory syncytial virus (RSV) infection increases progressively with age and is more likely among people with other health issues and who live in nursing homes, according to a study published in Eurosurveillance. The hospitalisation rate varied considerably with age and the presence of risk conditions, with important implications for possible targeted interventions.
This population-based cohort study analysed patient data for adults over the age of 60 years in seasons 2016/17 to 2019/20 obtained through electronic medical records ...

TAMPA, Fla. (March 13, 2025) – The Great Atlantic Sargassum Belt has puzzled researchers since 2011. A recent study published in Nature Communications may have identified what drove a tipping point that established the phenomenon in the tropical Atlantic Ocean.
Using computer modeling, a team of international researchers demonstrated that sargassum blooms were brought to the tropics by strong ocean currents and wind and thrived in ideal growing conditions.
Specifically, two consecutive years of a strong negative North Atlantic Oscillation (NAO), a shift in atmospheric pressure over the Atlantic that changes circulation and wind patterns, pushed sargassum into the tropics starting ...
