Prior research linked a high preoperative neutrophil-to-lymphocyte ratio (NLR) to a worse prognosis in individuals with a variety of malignancies. This study aimed to establish the prognostic and predictive usefulness of preoperative NLR in colorectal cancer (CRC) patients and to identify an appropriate cut-off value for the NLR. We enrolled a total of 195 patients that underwent surgery for stage II and III colorectal cancer that required adjuvant chemotherapy as well as stage IV colorectal cancer patients treated with palliative intent. The mean NLR value was 3.42 +- 2.27. We used a receiver operating characteristic curve to estimate the optimum NLR cut-off value at 3. Patients with a NLR value above 3 were classified as high-NLR, while patients with a NLR below 3 were classified as low-NLR; Results Overall survival (OS) and progression-free survival (PFS) were significantly reduced in high-NLR patients. The overall response rate (ORR) was also lower in high-NLR patients. Conclusions Preoperative NLR is an accessible measurement that seems to have prognostic and predictive value in patients with colorectal cancer.

Impact of adjuvant chemotherapy on survival in ypT0-2 N0 rectal cancer.
Int J Colorectal Dis

Medical Oncology Department, National Cancer Institute, Cairo University, Giza, Egypt.
Purpose: The role of adjuvant chemotherapy in rectal cancer patients downstaged to ypT0-2 N0 after neoadjuvant chemoradiotherapy (CRT), and surgery is still debated. This study investigates the impact of adjuvant chemotherapy on survival outcomes in this patient population.
Methods: This retrospective study analyzed hospital records of rectal cancer cases from Shefa Al Orman Cancer Hospital between January 2016 and December 2020, focusing on patients downstaged to ypT0-2 N0 after neoadjuvant CRT and surgery.
Visible-light-induced CO-releasing properties and cytotoxicity of a Ru(II) carbonyl complex containing 2-(pyridin-2-yl)-quinoxaline.

Department of Chemistry, Faculty of Science, Cairo University, Gamma Street, Giza, Cairo 12613, Egypt.
The photo-induced CO-releasing properties of the dark-stable complex [RuCl(CO)L] (L = 2-(pyridin-2-yl)quinoxaline) were investigated under 468 nm light exposure in the presence and absence of biomolecules such as histidine, calf thymus DNA and hen egg white lysozyme. The CO release kinetics were consistent regardless of the presence of these biomolecules, suggesting that they did not influence the CO release mechanism. The quinoxaline ligand demonstrated exceptional cytotoxicity against human acute monocytic leukemia cells (THP-1), with evidence of potential DNA damage ascertained by comet assay, while it remained non-toxic to normal kidney epithelial cells derived from African green monkey (Vero) cell lines.

Int J Cancer

Division of Clinical Epidemiology and Aging Research, German Cancer Research Center (DKFZ), Heidelberg, Germany.
Studies aimed to evaluate the expected impact of alternative screening strategies are essential for optimizing colorectal cancer (CRC) screening offers, but such studies are lacking in Germany, where two screening colonoscopies (CS) 10 years apart are offered for men from age 50 and women from age 55. Our aim was to explore whether and to what extent the efficacy of utilizing two CS could be enhanced by alternative starting ages and screening intervals. We modeled the expected numbers of CRC cases, CRC deaths, years of potential life lost (YPLL), and disability-adjusted life years (DALYs) due to CRC in hypothetical cohorts of 100,000 men and women aged 45-85 using COSIMO, a validated Markov-based multi-state simulation model.

Cancer is a major health challenge globally and in Sri Lanka. Providing comprehensive information to patients is crucial for improving treatment outcomes and patient satisfaction, supported by evidence of its effectiveness in managing cancer pain. EORTC QLQ-INFO25, an information module developed by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group, is aimed at assessing cancer patients' perception of information received during different phases of care.
