Lung Cancer Europe study highlights communication gaps and need for shared decision-making

Complex medical language cited as main barrier to communication and understanding of lung cancer diagnosis

2025-09-09

(Press-News.org) (Barcelona, Spain September 9, 2025, 10:15 a.m. CEST / UTC +2) — A large-scale survey conducted by Lung Cancer Europe (LuCE) has identified critical communication barriers that affect information access, understanding, and shared decision-making among lung cancer patients and caregivers across Europe.

The research was reported at the International Association for the Study of Lung Cancer 2025 World Conference on Lung Cancer (WCLC).

The study, based on 2,040 valid survey responses from 34 WHO European Region countries in 20 languages, evaluated three key areas: general knowledge about lung cancer, access to information, and involvement in decision-making. The findings underscore the need for healthcare systems to improve communication practices and patient engagement to ensure more person-centered care.

Lung Cancer Europe (LuCE) is a nonprofit, patient-led organization that serves as the umbrella group for lung cancer advocacy organizations across Europe.

“Patients need information that is understandable, timely, and supports meaningful participation in their care,” said Debra Montague of LuCE, the presenting author. “Despite best intentions, current systems often fall short of empowering patients and caregivers to make informed decisions.”

Montague reported that 65% of participants delayed seeking care due to unrecognized symptoms and 22% were unaware of biomarkers, while 24% did not understand their prognosis.

She added that 40% said they did not receive enough information and 29% did not fully understand what they received.

“Patients told us that common barriers included information processing (39%), lack of clarity (33%), and complexity (33%),” she said. “Surprisingly, only 56% felt their opinion was considered in treatment decisions while 60% felt the care plan matched patient preferences.”

Montague reported that the top obstacle to shared decision-making was complex medical language (49%).

The majority of respondents (64%) valued both quality and length of life equally, though about one-third prioritized quality over quantity of life, underscoring the need for personalized care discussions.

Montague said she encourages healthcare providers, policymakers, and advocacy groups to collaborate to improve early diagnosis, enhance communication, and prioritize shared decision-making.

“Health providers must enable and implement shared decision-making to help enhance quality of life. Improved communication strategies are critical to deliver person-centered care,” Montague said.

Well-publicized polar geoengineering ideas will not help and could harm, warn experts

2025-09-09

Five well-publicized polar geoengineering ideas are highly unlikely to help the polar regions and could harm ecosystems, communities, international relations, and our chances of reaching net zero by 2050. This is according to a new assessment, published in Frontiers in Science, which looked at five of the most developed geoengineering proposals currently being considered for use in Antarctica and the Arctic. The polar regions are home to fragile communities and ecosystems, as well as most of the world’s ice. Technological ‘geoengineering’ approaches have been proposed to delay or address the impacts of climate ...

Racial stereotypes can make us see weapons where they don’t exist

2025-09-09

Unarmed Black civilians are three times more likely to be shot and killed by police officers than unarmed white civilians in the U.S. In tragic cases in recent years, unarmed Black men holding innocuous objects like a wallet, cell phone, or vape pen were killed by police officers because those objects were misidentified as weapons. These split-second fatal mistakes, often under ambiguous and stressful conditions, have sparked urgent debates about their causes and how to fix them. A new brain-imaging study from researchers at Columbia University ...

“Bottlebrush” particles deliver big chemotherapy payloads directly to cancer cells

2025-09-09

CAMBRIDGE, MA -- Using tiny particles shaped like bottlebrushes, MIT chemists have found a way to deliver a large range of chemotherapy drugs directly to tumor cells. To guide them to the right location, each particle contains an antibody that targets a specific tumor protein. This antibody is tethered to bottlebrush-shaped polymer chains carrying dozens or hundreds of drug molecules — a much larger payload than can be delivered by any existing antibody-drug conjugates. In mouse models of breast and ovarian cancer, the researchers found that treatment with ...

New AI tool pinpoints genes, drug combos to restore health in diseased cells

2025-09-09

In a move that could reshape drug discovery, researchers at Harvard Medical School have designed an artificial intelligence model capable of identifying treatments that reverse disease states in cells. Unlike traditional approaches that typically test one protein target or drug at a time in hopes of identifying an effective treatment, the new model, called PDGrapher and available for free, focuses on multiple drivers of disease and identifies the genes most likely to revert diseased cells back to healthy function. The ...

Predicting where deadly brain cancer may spread next

2025-09-09

Glioblastoma is a devastatingly effective brain cancer. Doctors can cut it out or blast it with radiation, but that only buys time. The cancer has an insidious ability to hide enough tumor cells in tissue around the tumor to allow it to return as deadly as ever. Patients diagnosed with glioblastoma survive for an average of 15 months. What’s needed is a better way of identifying those hidden cancer cells and predicting where the tumor might grow next. Jennifer Munson believes she and her research team at the Fralin Biomedical Research Institute at VTC have developed a tool to do just that. Their method, described ...

First ever measure of boron in individual cancer cells could revolutionise drug understanding

2025-09-09

A new technique has measured boron in individual cancer cells for the first time, enabling researchers to better understand how drugs act to kill tumours in some cancers. In a new article in the Journal of Analytical Atomic Spectrometry, a team from the University of Birmingham funded by the Rosetrees Trust have for the first time used a technology to conduct real-time measurement of boron in live tumour cells. The technique, called single-cell ICP-MS, enabled the team to see how and when treatments for head and neck cancers enter and exit tumour cells. Boron Neutron Capture Therapy (BNCT) is a new form of therapeutic for head and neck cancer that involves ...

Graz researchers discover what stiffens the aorta

2025-09-09

Cardiovascular diseases remain the most common cause of death worldwide. In Europe, they account for over 40 percent of all deaths. However, known risk factors such as high cholesterol levels or high blood pressure cannot fully explain the high mortality rate or the number of cardiovascular diseases. Scientists in Graz have now investigated a new factor that is closely linked to cardiovascular mortality. Elevated levels of the amino acid homocysteine in the blood led to a stiffer and less elastic aorta in an animal model. These findings contribute to the current understanding ...

Breakthrough in atomic-level etching of hafnium oxide, a promising material for advanced semiconductors

2025-09-09

Hafnium oxide (HfO2) has attracted attention as a promising material for ultrathin semiconductors and other microelectronic devices. The strong ionic bond between hafnium and oxygen atoms in HfO2 gives it a high dielectric constant, superior thermal stability, and a wide band gap. Notably, these properties can be maintained even at the atomic scale. Meanwhile, these properties also pose challenges in achieving highly precise and smooth etching of HfO2 films. Now, a group of researchers from Japan and Taiwan has successfully etched HfO2 films with atomic-level precision, smoothness, ...

How evolution explains autism rates in humans

2025-09-09

A new paper in Molecular Biology and Evolution, published by Oxford University Press, finds that the relatively high rate of Autism-spectrum disorders in humans is likely due to how humans evolved in the past. About one in 31 (3.2%) children in the United States has been identified with Autism Spectrum Disorder. Globally, the World Health Organization estimates that around one in 100 children have autism. From an evolutionary perspective, many scientist believe that autism and schizophrenia may be unique to humans. ...
