Background: The Surveillance, Epidemiology and End Results (SEER) and the National Cancer Database (NCDB) are databases for cancer analysis that may be subject to error in data reporting. This study examined the rates and impact of discordant data for non-small cell lung cancer.
Methods: NCDB and SEER were queried for non-small cell lung cancer pathologic tumor, node, metastasis data (NCDB) or "derived" data (SEER). Discordancy between descriptors with stage and impact of outlier data were analyzed.
Results: Incomplete staging was noted in 71.5% of the NCDB and 10.3% of SEER patients. A total of 174 829 patients from the NCDB and 117 114 from SEER were analyzed. The NCDB had 97 cases with ≥20 positive lymph nodes recorded vs 27 in SEER (P < .001). Mean and median sampled lymph nodes were skewed with inclusion of these data points (P < .001). The NCDB misclassified 0.99% tumors >5 cm as stage I vs 0.04% in SEER (P < .001). The NCDB misstaged positive lymph nodes as pathologic N0 (0.59%) or stage 0 or stage I (0.65%). The NCDB misclassified pathologic N1 as lower than stage II (0.91%) or N2 as lower than stage III (0.36%). The NCDB misclassified stage I with documentation of pathologic N1 or N3 disease (0.24%) or stage II with evidence of N2 or N3 disease (0.50%). The NCDB misclassified pathologic M1 as pathologic stage
Conclusions: The NCDB and SEER are 2 powerful cancer databases. However, the cumulative discordancy rate was 4.9% for the NCDB and 0.008% for SEER, with more misstaging and outliers in the NCDB.

Tumor cell-intrinsic signaling pathways can drastically affect the tumor immune microenvironment, promoting tumor progression and resistance to immunotherapy by excluding immune-cell populations from the tumor. Several tumor cell-intrinsic pathways have been reported to modulate myeloid-cell and T-cell infiltration creating "cold" tumors. However, clinical evidence suggests that excluding cytotoxic T cells from the tumor core also mediates immune evasion.

Antibodies targeting immune checkpoints, such as PD-1, PD-L1, or CTLA-4, have transformed the treatment of patients with lung cancers. Unprecedented rates of durable responses are achieved in an imperfectly characterized population of patients with metastatic disease. More recently, immune checkpoint inhibitors have been explored in patients with resectable non-small-cell lung cancers.

Background: Accurate data on the prognosis of bone metastases are necessary for appropriate treatment. Immune checkpoint inhibitors (ICIs) are widely used in the treatment of gene mutation-negative non-small cell lung cancer (GMN-NSCLC).
Aim: To investigate the prognostic factors in patients with bone metastases from GMN-NSCLC following ICI use.

Ion channels, as functional molecules that regulate the flow of ions across cell membranes, have emerged as a promising target in cancer therapy due to their pivotal roles in cell proliferation, metastasis, apoptosis, drug resistance, and so on. Recently, increasing evidence suggests that dysregulation of ion channels is a common characteristic of cancer cells, contributing to their survival and the resistance to conventional therapies. For example, the aberrant expression of sodium (Na) and potassium ion (K) channels is significantly correlated with the sensitivity of chemotherapy drugs.

Pembrolizumab (an anti-PD1 antibody) alone or combined with chemotherapy represented the standard of care for advanced non-oncogene addicted non-small cell lung cancer (NSCLC) patients. These therapies induced early modifications of the immune response impacting the clinical outcome. Identifying early changes in the immune system was critical to directing the therapeutic choice and improving the clinical outcome.
