Lack of Association Between Radiographic Tumor Burden and Efficacy of Immune Checkpoint Inhibitors in Advanced Lung Cancer.
CONCLUSION: Although tumor burden has been considered a mediator of efficacy of earlier immunotherapies, in advanced lung cancer it does not appear to affect outcomes from immune checkpoint inhibitors. IMPLICATIONS FOR PRACTICE: Historically, tumor burden has been considered an impediment to the efficacy of various immunotherapies, including vaccines, cytokines, allogeneic stem cell transplant, and intravesical bacillus Calmette-Guérin. However, in the present study, no association was found between tumor burden and efficacy (response rate, progression-free survival, overall survival) of immune checkpoint inhibitors in advanced lung cancer. These findings suggest that immune checkpoint inhibitors may provide benefit across a range of disease burden, including bulky tumors considered resistant to other categories of immunotherapy.

Conclusions: In this cohort, only 35.1% of patients eligible for post-PD1 Ab therapy received st. Post-progression survival was not significantly affected by receipt of post-progression therapy. Prospective trials are needed to clarify the benefit of post-PD1 Ab treatments. PMID: 32489249 [PubMed - in process]
Conclusions: The elcss-ql is feasible as a tool for use in routine clinical practice, although no statistically significant effect of its use was demonstrated in our study. Improving access to supportive care through the collection of patient-reported outcomes and hrqol should be an important component of care for patients with advanced lung cancer.

Interview with Chad G. Rusthoven, MD, author of Evaluation of First-line Radiosurgery vs Whole-Brain Radiotherapy for Small Cell Lung Cancer Brain Metastases: The FIRE-SCLC Cohort Study
This study aims to evaluate micronuclei (MN) frequency as a biomarker of genome instability in peripheral blood lymphocytes of PM and lung cancer (LC) patients when compared with healthy controls (HCs) and patients with nonneoplastic respiratory diseases (RDs). Lymphocyte cytokinesis-block MN assay was carried out on 317 subjects. Mutagen sensitivity, measured by quantifying MN frequency after an in vitro challenge with ionizing radiation, was evaluated in 252 subjects. A significant increase in MN frequency was observed in cancer patients compared to HCs, with a mean ratio (MR) of 1.35 and 1.36 at baseline and 1.43 and 1....

Authors: Gordon N, Felix K, Daw NC Abstract Inhalation therapy remains a suitable approach to treat lung diseases including cancer. This approach has been used to deliver various therapies including chemotherapy. The rationale for using the inhalation route vs. the systemic route has been the fewer side effects encountered when drugs are administered via inhalation. Furthermore, this approach overcomes one of the major limitations of systemic chemotherapy that results from inability of the drug to reach high concentrations in the lungs. Local delivery overcomes this limitation and spares exposure of vital organs to...
(Wake Forest Baptist Medical Center) Among people who have the most common type of lung cancer, up to 40% develop metastatic brain tumors, with an average survival time of less than six months. But why non-small-cell lung cancer so often spreads to the brain has been poorly understood.
