Key clinical point: A new breath biomarker-based diagnostic method shows promise by identifying 16 cancer-derived volatile organic compounds (VOC) that have high sensitivity and specificity in patients with lung cancer.

Major finding: In the discovery phase, 16 VOC with peak intensity most altered before vs after surgery were identified. In the validation phase, the 16 VOC-based diagnostic model demonstrated an area under the curve of 0.952, sensitivity of 89.2%, specificity of 89.1%, and accuracy of 89.1%.

Study details: The discovery phase involved a prospective cohort study of 84 patients with lung cancer who were tested for 28 VOC before and after surgery. The promising VOC were further assessed in the validation phase which included 157 patients with lung cancer and 368 healthy controls.

Disclosures: The research was funded by the National Natural Science Foundation of China and others. The authors declared no competing interests.

Key clinical point: In patients with stage I lung cancer treated with stereotactic body radiation therapy (SBRT), a model incorporating noncancerous imaging features on chest computed tomography (CT) and clinical features vs clinical features alone performed better at predicting overall survival (OS).

Major finding: The model that incorporated both clinical and imaging features vs the model that incorporated only clinical features performed better at predicting 5-year OS (area under the curve 0.75 vs 0.61; P < .01). Independent risk factors for shorter OS were elevated coronary artery calcium score, increased pulmonary artery-to-aorta ratio, and decreased thoracic skeletal muscle index.

Study details: The data come from a retrospective study involving 282 patients with stage I lung cancer treated with SBRT. Several clinical markers were assessed from pretreatment chest CT images.

Disclosures: No funding information was available. The corresponding author FJ Fintelmann reported no relevant financial relationships.

Key clinical point: The addition of nivolumab to neoadjuvant chemotherapy is more efficacious than and comparably safe compared to chemotherapy alone in patients with stage IB-IIIA resectable nonsmall cell lung cancer (NSCLC).

Major finding: The nivolumab plus chemotherapy vs chemotherapy-alone group demonstrated longer event-free survival (31.6 vs 20.8 months; hazard ratio 0.63; P = .005) and had a higher proportion of patients achieving pathological complete response (24.0% vs 2.2%; odds ratio 13.94; P < .001). The rates of grade 3/4 treatment-related adverse events were comparable between the groups (33.5% vs 36.9%).

Study details: The data come from an open-label phase 3 CheckMate 816 trial which included patients with resectable NSCLC who were randomly assigned to receive neoadjuvant nivolumab plus platinum-doublet chemotherapy (n = 179) or platinum-doublet chemotherapy alone (n = 179).

Disclosures: The trial was funded by Bristol Myers Squibb. The authors reported ties with one or more pharmaceutical companies outside this work, including Bristol Myers Squibb.

Some smokers might not get lung cancer because of their DNA, researchers report in a new study.

These people have genes that help limit mutations to DNA that would turn cells malignant and make them grow into tumors, the researchers say.

Scientists have long suspected that smoking leads to lung cancer by triggering DNA mutations in healthy cells. But it was hard for them to identify the mutations in healthy cells that might help predict future cancer risk, Jan Vijg, PhD, a senior author of the study and researcher at the University School of Medicine, Shanghai, China, said in a statement.

His team used a process called single-cell whole genome sequencing to examine cells lining the lungs of 19 smokers and 14 nonsmokers ranging in age from their pre-teens to their mid-80s. The cells came from patients who had tissue samples collected from their lungs during diagnostic testing unrelated to cancer. The scientists reported their findings in Nature Genetics.

The researchers specifically looked at cells lining the lungs because these cells can survive for years and build up mutations over time that are linked to aging and smoking.

“Of all the lung’s cell types, these are among the most likely to become cancerous,” says Simon Spivack, MD, a senior author of the study and professor at the Albert Einstein College of Medicine, New York.

Smokers had far more gene mutations that can cause lung cancer than nonsmokers, the analysis found.

“This experimentally confirms that smoking increases lung cancer risk by increasing the frequency of mutations, as previously hypothesized,” says Dr. Spivack. “This is likely one reason why so few nonsmokers get lung cancer, while 10 to 20 percent of lifelong smokers do.”

Among the smokers, people had smoked a maximum of 116 pack-years. A pack-year is the equivalent of smoking one pack a day for a year. The number of mutations detected in smokers’ lung cells increased in direct proportion to the number of pack-years they smoked.

But after 23 pack-years, the lung cells in smokers didn’t appear to add more mutations, the researchers report, suggesting that some people’s genes might make them more likely to fight mutations.

“The heaviest smokers did not have the highest mutation burden,” says Dr. Spivack. “Our data suggest that these individuals may have survived for so long in spite of their heavy smoking because they managed to suppress further mutation accumulation.”

While it’s possible these findings could one day help doctors come up with better ways to screen for lung cancer and treat the disease, that’s still a long way off. Many more lab tests and larger studies will be needed to better pinpoint which smokers might be more prone to lung cancer and why.
