High neutrophil, low lymphocyte and hemoglobin unfavorably impact survival in non-small cell lung cancer patients with brain metastases

Background Brain metastases (BM) from NSCLC has emerged as an increasingly corresponding clinical problem. Precise prognostic evaluation is the basis for personalized medicine. This study sought to investigate prognostic values of clinical and hematological indicators for NSCLC patients with BM in the real world, which could further help guide survivorship care in the actual clinical setting and clinical trials. Materials and Methods We retrospectively reviewed the clinical and hematological indicators of NSCLC patients with BM treated with whole-brain radiotherapy. Receiver operating characteristic curve was performed to evaluate the optimal cut-off point. Kaplan–Meier survival analysis and Cox regression analyses were used to evaluate survival. Results 105 patients were included and median survival was 21 months (range: 1–64 months). Univariate analyses demonstrated that favorable survival was associated with resection history of NSCLC (P = 0.015), absent of intracranial symptom (P = 0.044), lymphocyte ≥ 1.54*109/L(P < 0.001), neutrophil < 4.64*109/L (P = 0.016), hemoglobin ≥ 117.5 g/L (P < 0.001), BSBM scores of 2–3 (P = 0.033) and Lung-molGPA scores of 2.5-4 (P < 0.001). Cox regression analysis showed that lymph...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Landau-Kleffner Syndrome

Landau Kleffner syndrome (LKS), also called infantile acquired aphasia, acquired epileptic aphasia, or aphasia with convulsive disorder, is a rare childhood neurological syndrome characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electroencephalogram. Discover the latest research on LKS here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.
