Moffitt Research advocates for routine brain MRI screening in asymptomatic late stage breast cancer patients

New study shows brain metastasis is more common than previously thought, regardless of breast cancer subtype

2025-01-28

(Press-News.org) TAMPA, Fla. (Jan. 28, 2025) — A new study led by researchers at Moffitt Cancer Center shows that asymptomatic brain metastasis is more common in stage 4 breast cancer patients than previously believed. The study, published in Neuro-Oncology, suggests that doctors may need to rethink current screening guidelines for detecting brain metastasis in patients without symptoms.

Researchers examined 101 asymptomatic patients diagnosed with stage 4 breast cancer, including triple-negative, HER2-positive and hormone receptor-positive/HER2-negative breast cancer. These patients underwent MRI scans to check for brain metastasis, with a follow-up MRI six months later if the initial scan showed no signs of cancer spread.

Of the patients who completed the initial MRI, 14% had brain metastasis. The rates by subtype were:

18% in triple-negative breast cancer 15% in HER2-positive breast cancer 10% in hormone receptor-positive/HER2-negative breast cancer After the second MRI, the number of patients with brain metastasis grew to about 25% in each subtype. Following diagnosis, patients went on to receive early treatment for their brain metastases, including changes in systemic therapy and local therapies.

“Our study suggests that asymptomatic brain metastasis is quite common in stage 4 breast cancer,” said Kamran Ahmed, M.D., associate member and section chief for Breast Radiation Oncology at Moffitt and principal investigator of the study. “Although larger studies are needed to confirm our findings, given the improvements in systemic and local therapies for breast cancer brain metastasis, the time may be appropriate to reconsider current guidelines that recommend against routine MRI surveillance in late stage breast cancer.”

This study was supported by the Florida Breast Cancer Foundation.

More primary care physicians are affiliated with hospitals, leading to increased patient costs

2025-01-28

PROVIDENCE, R.I. [Brown University] — A study by researchers at the Brown University School of Public Health shows that nearly half of all primary care providers (PCPs) in the United States are affiliated with hospitals, while the number of PCPs affiliated with private equity firms is growing and concentrated in certain regional markets. Compared with PCPs at independent practices, those affiliated with hospitals or private equity firms charged higher prices for the same services. The findings were published in JAMA Health Forum. Health care consolidation is a driving force behind ...

Western Kenyan farmers favor restoring land with native trees. Yet barriers remain

2025-01-28

African nations have grand ambitions to green up landscapes with trees; the Kenyan government, for example, launched an initiative to plant 15 billion trees by 2032. The hope is that new trees could help fight desertification, create opportunities for livelihood diversification, support nutritional diets, restore biodiversity in highly degraded land and capture planet-heating carbon. Restoring lands using trees could empower millions whose livelihoods depend on working the land while generating multiple environmental and social benefits. Yet tree planting projects often fall short because ...

Inherited gene elevates prostate cancer risk in affected families

2025-01-28

A study of men with a family history of prostate cancer has discovered an inherited form of prostate cancer. The inherited mutated gene WNT9B, which functions normally in embryonic prostate development, increases risk of adult prostate cancer, according to the Vanderbilt University Medical Center study published in JCO Precision Oncology. This discovery was replicated in five independent study populations collectively encompassing one-half million patients from the U.S. and Europe, with the increased prostate cancer risk estimates ranging from two- to 12-fold, according to lead author Jeffrey Smith, MD, PhD, associate ...

Rice SynthX and MD Anderson team awarded Kleberg medical grant for brain metastasis research

Rice University chemist and director of the university’s Synthesis X Center Han Xiao and cancer biologist Dihua Yu of The University of Texas MD Anderson Cancer Center have received a three-year, $1.5 million grant from the Robert J. Kleberg Jr. and Helen C. Kleberg Foundation, allowing them to do further research on overcoming the blood-brain barrier (BBB) for the treatment of brain metastasis. This hurdle blocks most cancer therapies from reaching the brain, but the scientists’ innovative approach could transform the treatment of brain ...

Researchers identify genetic ‘fingerprint’ to predict drug resistance in bacteria

2025-01-28

Antibiotic resistance is a global public health crisis responsible for more than a million deaths annually. By 2050, the World Health Organization estimates it could surpass cancer and heart disease as the leading cause of death as more bacteria develop defenses to the drugs designed to combat them. Now Tulane University researchers have identified a unique genetic signature in bacteria that can predict their likelihood of developing antibiotic resistance, according to a new study published in Nature Communications. The findings could help researchers more quickly identify precision-based treatments that are more effective ...

Explaining persistent hydrogen in Mars’ atmosphere

2025-01-28

The fact that the cold, dry Mars of today had flowing rivers and lakes several billion years ago has puzzled scientists for decades. Now, Harvard researchers think they have a good explanation for a warmer, wetter ancient Mars. Building on prior theories describing the Mars of yore as a hot again, cold again place, a team led by researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have determined the chemical mechanisms by which ancient Mars was able to sustain enough warmth in its early days ...
