Abstract The association between sepsis and segmented neutrophil-to-monocyte (SeMo) ratio is unclear. We postulated that an increase in dynamic SeMo measurement can be applied risk stratification. This retrospective study included 727 consecutive patients medical intensive care units (ICUs), including a subpopulation of 153 patients. According to the leukocyte (white blood cell, WBC) count on day 3 (normal range, 4,000/µL 12,000/µL) delta (value minus value 1; normal SeMo, <7), were...

Among epidermal growth factor receptor (EGFR) mutation status unknown nonsmall cell lung cancer (NSCLC) patients, those with higher carcinoembryonic antigen (CEA) level are more likely to response EGFR-tyrosine kinase inhibitors (TKIs) because they tend have mutant (EGFR). However, patients CEA also tumor burden. With the above paradoxical evidence, it is prudent understand prognostic significance of baseline in EGFR-mutant NSCLC treated first-line EGFR-TKIs.
