(Press-News.org) (Barcelona, Spain September 8, 2025, 10:45 a.m. CEST / UTC +2) – Patients who underwent video-assisted thoracoscopic surgery (VATS) compared to open lobectomy had a significantly improved overall survival rate, according to a meta-analysis presented at the International Association for the Study of Lung Cancer (IASLC) 2025 World Conference on Lung Cancer (WCLC).
Video-assisted thoracoscopic surgery (VATS) is currently the most common approach to perform pulmonary lobectomy in early-stage lung cancer. Advantages include reduced pain, fewer complications, faster recovery and improved quality-of-life. The adoption of VATS lobectomy is based on proven non-oncological benefits.
According to Dr. Jacie Jiaqi Law, Royal Brompton Hospital, United Kingdom, none of the three largest contemporary randomized trials completed have been powered to detect a difference in overall or disease-free survival. Several meta-analyses of predominantly non-randomized studies have suggested a VATS approach leads to improved patient survival compared to thoracotomy, however findings are limited due to selection bias and confounding, Dr. Law reported.
To answer this important question, Dr. Law and fellow researchers sought to identify randomized trials comparing VATS and open lobectomy in early-stage lung cancer and obtain individual patient data from these trials to conduct a meta-analysis.
Of the 556 potential studies identified, only three were randomised trials that met the eligibility criteria: Bendixen et al. from Denmark (NCT01278888), Long et al. from China (NCT01102517) and Lim et al. from the United Kingdom (NCT03521375). Data on 1185 patients (586 randomized to VATS and 599 randomized to open lobectomy) was provided from the three trials.
The primary analysis indicated significantly improved overall survival for patients randomized to VATS compared to open lobectomy, pooled hazard ratio (HR) 0.79 (95% confidence interval (CI) 0.65-0.96), representing a 21% reduction in the risk of death in the VATS lobectomy group. There was no difference in disease-free survival, pooled HR 0.91 (95% CI 0.75-1.12).
“For the first time, we provide evidence that a simple change in surgical access to VATS reduces the overall risk of death by 21% without any compromise to disease-free survival,” Dr. Law reported. “These results underscore the importance of prioritizing VATS when technically feasible as the access of choice for surgical resection of early-stage non-small cell lung cancer.”

(Barcelona, Spain September 8, 2025, 10:45 a.m. CEST / UTC +2) – Interim results from the NADIM ADJUVANT Phase III trial, led by the Spanish Lung Cancer Group (GECP), suggest that adjuvant chemo-immunotherapy may reduce the risk of recurrence in patients with completely resected stage IB–IIIA non-small cell lung cancer (NSCLC) while maintaining an acceptable safety profile.
Despite complete surgical resection (R0), early-stage NSCLC carries a substantial risk of recurrence and remains a leading cause of cancer-related ...

In Europe, almost one in 10 people over 70 suffers from dementia, and this figure could even triple by 2050 due to rising life expectancy. Over time, those affected lose everything that makes them who they are, including their memory and their ability to go about their everyday lives. Many also suffer from physical deterioration. In an advanced stage of the disorder, dementia patients generally require comprehensive care.
Now, the first drugs have emerged that can slightly slow down disease progression in the early stages of Alzheimer’s – ...
New research indicates that many patients who undergo surgery with the intent to cure early-stage cancer continue or start opioid prescriptions in the year following surgery. The findings are published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.
Pain management is essential during cancer care, but prescription opioid practices associated with cancer treatment may lead to unsafe long-term opioid use and adverse outcomes such as opioid use disorder and opioid overdose. To assess the ...
Black adolescents with mental distress are less likely to use mental health services than their White peers, and Black girls are the least likely to access care, according to new research published in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.241733.
“Adolescence is a crucial developmental stage and a critical period for onset of mental health problems,” writes Mercedes Sobers, a PhD candidate in epidemiology at the Dalla Lana School of Public Health, University of Toronto and research coordinator at the Centre for Addiction and Mental Health (CAMH), Toronto, Ontario, ...
Canada must enact strong, effective legislation to protect youth from gambling advertising. Minors are suffering harms from problem gambling despite age restrictions, argue authors in an editorial in CMAJ (Canadian Medical Association Journal) https://www.cmaj.ca/lookup/doi/10.1503/cmaj.251227 .
Since 2021, ads for sports betting have saturated sports broadcasts, constantly viewed by children. Gambling is normalized as a natural part of spectatorship at a young age. Even before single-game sports betting was legalized, a 2019 survey of Canadian students in grades 7–12 found about 4% of students ...

Research Highlights:
Children who had higher blood pressure at age 7 were more likely to die early from cardiovascular disease by their mid-50s. The risk was highest for children whose blood pressure measurements were in the top 10% for their age, sex and height.
Both elevated blood pressure (90-94th percentile) and hypertension (≥95th percentile) were linked with about a 40% to 50% higher risk of early cardiovascular death in adulthood.
Researchers said their findings show why it’s important to regularly check children’s blood pressure and to help them develop heart-healthy habits early that can help lower their ...
Research Highlights:
Use of an AI voice agent to prompt self-reported blood pressure readings helped to improve accuracy of blood pressure measures and patient outcomes in a group of majority ages 65 and older patients with high blood pressure.
The study’s findings demonstrate how integrating AI into care can help to improve home blood pressure monitoring and completion rates, which can lead to improved quality outcomes for patients.
