(Press-News.org)
In this April 2025 issue of Annals of Thoracic Surgery (JCR Q1, IF: 3.6), a retrospective study, led by Professors Jianxing He and Shuben Li from the First Affiliated Hospital of Guangzhou Medical University, illustrated the safety, feasibility, and efficacy of extended sleeve lobectomy (ESL) after neoadjuvant immunochemotherapy in patients with centrally located non-small cell lung cancer (NSCLC).
The article entitled "Extended Sleeve Lobectomy After Neoadjuvant Immunochemotherapy for Centrally Located Non-small Cell Lung Cancer". It is the first study to evaluate the impact of neoadjuvant immunochemotherapy on ESL. The results demonstrated that ESL after neoadjuvant immunochemotherapy is a viable and safe option for selected patients with centrally located NSCLC to avoid pneumonectomy(PN), especially when standard sleeve lobectomy (SSL) is insufficient for R0 resection.
【Backgrounds】
Centrally located non-small cell lung cancer (NSCLC) often necessitates extensive parenchymal resection due to its aggressive nature and proximity to critical bronchovascular structures. Historically, PN has been regarded as the gold standard treatment for patients with central tumors. However, PN is associated with higher rates of mortality and morbidity, and significantly compromises pulmonary reserve, resulting in a substantial decline in lung function and quality of life.
Bronchoplasty techniques have emerged as promising alternatives for treating central NSCLC. Sleeve lobectomy (SL) has demonstrated more favorable outcomes than PN. When standard sleeve lobectomy (SSL) is not feasible, extended sleeve lobectomy (ESL) offers a potential solution to avoid PN. The safety and efficacy of SSL after neoadjuvant immunochemotherapy have been well confirmed. However, the safety and feasibility of ESL after such therapy remains controversial.
【Main findings】
A total of 94 patients with central non-small cell lung cancer (NSCLC) received neoadjuvant immunochemotherapy, followed by PN, ESL, or SSL, were retrospective collected. R0 resection was confirmed in 90 patients (95.7%), including 17 (94.4%) in ESL, 41 (97.6%) in SSL, and 32 (94.1%) in PN (P=0 .72). The result showed that the overall postoperative complication rate was 18.1% (17 of 94). Postoperative complications were predominantly observed in patients who underwent PN (32.4%), although the difference between ESL and pneumonectomy groups was not statistically significant. Kaplan-Meier curves showed no difference between ESL and SSL. Compared with PN, ESL had a longer event-free survival (P=0.04).
【Clinical significance】
ESL after neoadjuvant immunochemotherapy may be a safe and feasible alternative to pneumonectomy for selected patients with centrally located NSCLC. Despite its technical complexities, ESL may optimize outcomes by preserving lung function, reducing perioperative morbidity, and enabling adjuvant therapy access.

Past years have witnessed impressive successes for tree models, while an important problem is to understand their predictions, especially for some critical applications. Previous interpretation methods for tree models focus on measuring the importance of individual features while ignoring plentiful correlations and structures among multiple features.
To solve the problems, a research team led by Wei GAO published their new research on 15 May 2025 in Frontiers of Computer Science co-published by Higher Education Press and Springer Nature.

The military prides itself on loyalty and respect but those values must extend to how they treat those who leave service, new research from Flinders University reveals.
Led by Australian Army veteran and Flinders University PhD Candidate Cameron Grant, the study analysed responses from nearly 400 former Australian Defence Force (ADF) members, uncovering widespread dissatisfaction with their discharge experience.
“The discharge process represents a complete severance of all military status, which can be extremely challenging in and of itself, but if that process is also unpleasant it can ...

Women who experience complications during pregnancy face a higher risk of stroke in the following decades according to research published in the European Heart Journal [1] today (Tuesday).
The study, which included data on more than two million women over more than 40 years, found an increased risk for women who had diabetes or high blood pressure while pregnant, a preterm delivery or a baby with a low birth weight.
Researchers say these common pregnancy complications could act as an early signal for cardiovascular problems in the future, meaning women could receive help early in life to lower their risk of ...

A landmark study by WEHI scientists has shed new light on one of the most fundamental mysteries of biology: how cells divide and grow into the complex structures that make up our bodies.
The study has produced a sophisticated and leading new technology for tracking cells very early during embryo development, as they divide, migrate and specialise into the organs, tissues and systems that keep us alive.
The innovative tech, called LoxCode, provides each cell in a genetically engineered mouse with one of billions of individual DNA barcodes, allowing them to be tracked in unprecedented detail.

Skin grafts genetically engineered from a patient’s own cells can heal persistent wounds in people with an extremely painful dermatologic disease, a Stanford Medicine-led clinical trial has shown. The grafts treat severe dystrophic epidermolysis bullosa, or EB, a genetic condition in which the skin is so fragile the slightest touch can cause blistering and wounds, eventually leading to large, open lesions that never heal and are immensely painful.
A phase 3 clinical trial showed that EB patients experienced significantly better healing, less pain and less itching from wounds treated ...

Endoscopies could be replaced by far less invasive capsule sponge tests for half of all patients with Barrett’s oesophagus, a known precursor to oesophageal cancer, according to a new study from researchers at the University of Cambridge, Addenbrooke’s Hospital and Queen Mary University of London.
The capsule sponge test is easier to administer and could be carried out by nurses and at GP practices, reducing the burden on NHS resources.
Oesophageal cancer is difficult to treat, with fewer than one in five patients surviving for five or more years following ...

New research has cast doubts over suggestions an incestuous social elite ruled over the ancient people of Ireland more than 5,000 years ago.
Researchers examined the evidence from burials of individuals at the Newgrange prehistoric monument in Ireland - a large circular mound containing a chamber where cremated and unburnt human remains were placed, the discovery of which led to speculation that those buried there must have been from an elite class or a royal family.
In 2020, the DNA analysis of a bone skull fragment found in the chamber, however, suggested that at least one of the individuals buried there was the result of a relationship ...
