Background: The purpose of this study was to analyze the predictive value of neutrophil/lymphocyte ratio (NLR) to better clarify which patient groups will benefit the most from particular treatments like bevacizumab.
Materials And Methods: A total of 245 treatment-naive metastatic colorectal cancern (mCRC) patients were retrospectively enrolled and divided into 2 groups: 145 group A patients were treated with chemotherapy in combination with bevacizumab, and 100 group B patients were treated as above without bevacizumab.
Results: Group A patients had better median overall survival (OS) and progression-free survival (PFS) (24.0 and 9.0 months) than group B patients (20 and 6.0 months) (p=0.033; p=0.015). In patients with low NLR, OS and PFS were significantly longer in group A patients (27 vs 18 months, p=0.001; 11 vs 7 months, p=0.017).
Conclusions: We conclude that NLR, a basal cancer related inflammation marker, is associated with the resistance to bevacizumab- based treatments in mCRC patients.

Background: We assessed association among household income, overall survival (OS), and cancer-specific survival (CSS) after proctectomy for rectal cancer.
Methods: Population-based cohort study included stage I-III rectal adenocarcinoma patients who underwent proctectomy (2010-2020), subdivided by household income at diagnosis [low (<$50,000), average ($50,000-74,999), above-average (≥$75,000)] and compared.
Results: Of 39,185 patients (59 % male; mean age 60.
Feasibility of detecting non-small cell lung cancer using exhaled breath condensate metabolomics.

Lung cancer is one of the most common malignancy in the world, and early detection of lung cancer remains a challenge. The exhaled breath condensate (EBC) from lung and trachea can be collected totally noninvasively. In this study, our aim is to identify differential metabolites between non-small cell lung cancer (NSCLC) and control EBC samples and discriminate NSCLC group from control group by orthogonal projections to latent structures-discriminant analysis (OPLS-DA) models.

Objective: The potential of robot-assisted (RA) single-position (SP) lateral lumbar interbody fusion (LLIF) warrants further investigation. This study aimed to assess the efficacy of RA-SP-LLIF in improving both clinical and radiographic outcomes in patients undergoing lumbar spinal fusion surgery.
Methods: A total of 59 patients underwent either RA-SP-LLIF (n = 31 cases) or traditional LLIF (n = 28 cases).
Impact of pedicle screw accuracy on clinical outcomes after 1- or 2-level minimally invasive transforaminal lumbar interbody fusion.

Objective: When creating minimally invasive spine fusion constructs, accurate pedicle screw fixation is essential for biomechanical strength and avoiding complications arising from delicate surrounding structures. As research continues to analyze how to improve accuracy, long-term patient outcomes based on screw accuracy remain understudied. The objective of this study was to analyze long-term patient outcomes based on screw accuracy.
