Recent Advances and Current Challenges in Stereotactic Body Radiotherapy for Ultra-Central Lung Tumors.

Stereotactic body radiotherapy has been established as a viable treatment option for inoperable early-stage non-small cell lung cancer or secondary lesions mainly in oligoprogressive/oligometastatic scenarios. Treating lesions in the so-called "no flight zone" has always been challenging and conflicting data never cleared how to safely treat these lesions. This is truer considering ultra-central lesions, i.

Clinical utility of Next Generation Sequencing of plasma cell-free DNA for the molecular profiling of patients with NSCLC at diagnosis and disease progression.

Background: The present study evaluates the utility of NGS analysis of circulating free DNA (cfDNA), which incorporates small amounts of tumor DNA (ctDNA), at diagnosis or at disease progression (PD) in NSCLC patients.

Methods: Comprehensive genomic profiling on cfDNA by NGS were performed in NSCLC patients at diagnosis (if tissue was unavailable/insufficient) or at PD to investigate potential druggable molecular aberrations. Blood samples were collected as routinary diagnostic procedures, DNA was extracted, and the NextSeq 550 Illumina platform was used to run the Roche Avenio ctDNA Expanded Kit for molecular analyses.

Immune-checkpoint inhibition in stage III unresectable NSCLC: Challenges and opportunities in the post-PACIFIC era.

The PACIFIC trial marked a new era in the treatment of stage III unresectable NSCLC, establishing durvalumab consolidation as new standard of care worldwide, with about 14 % increase of long-term survival and half of the patients alive at 4 years. A series of intensified immune-checkpoint inhibition regimens are currently under investigation in clinical trials in order to optimize the therapeutic benefit obtained in this population, while the identification of personalized approaches as well as the development of effective treatments in the post-durvalumab progression setting represent an actual and controversial topic for clinical lung cancer research. This review describes the current real-word treatment scenario for stage III unresectable NSCLC in Italy, and provides an updated overview of the upcoming therapeutic strategies under clinical investigation, discussing the most relevant challenges and opportunities featuring the post-PACIFIC era.

Predictive ability of a drug-based score in patients with advanced non-small-cell lung cancer receiving first-line immunotherapy.

Background: We previously demonstrated the cumulative poor prognostic role of concomitant medications on the clinical outcome of patients with advanced cancer treated with immune checkpoint inhibitors, creating and validating a drug-based prognostic score to be calculated before immunotherapy initiation in patients with advanced solid tumours. This 'drug score' was calculated assigning score 1 for each between proton-pump inhibitor and antibiotic administration until a month before cancer therapy initiation and score 2 in case of corticosteroid intake. The good risk group included patients with score 0, intermediate risk with score 1-2 and poor risk with score 3-4.
