Colorectal cancer (CRC) is well characterized in terms of genetic mutations and the mechanisms by which they contribute to carcinogenesis. Mutations in APC, TP53, and KRAS are common in CRC, indicating key roles for these genes in tumor development and progression. However, for certain tumors with low frequencies of these mutations that are defined by tumor location and molecular phenotypes, a carcinogenic mechanism dependent on BRAF mutations has been proposed.

Background: Postoperative pancreatic fistula (POPF) is one of the potentially serious complications after gastrectomy for gastric cancer (GC). Drain amylase level is a predictor of POPF in open and laparoscopic gastrectomy, but no study has focused on minimally invasive surgery (MIS), including robotic gastrectomy (RG). This study assesses the effect of drain amylase levels for POPF in MIS and develop a prediction model in the MIS era.

Background: Advanced gastric cancer with gastric outlet obstruction (GOO) causes malnutrition and medication adherence issues, leading to a poor prognosis. We developed a novel multimodal, less invasive treatment approach for gastric cancer patients with symptomatic GOO: laparoscopic stomach-partitioning gastrojejunostomy (LSPGJ) combined with neoadjuvant chemotherapy (NAC), followed by minimally invasive gastrectomy with reuse of gastrojejunostomy. This study is a retrospective analysis of the safety and feasibility of our treatment strategy.

Article Synopsis
  • - This study focused on 111 patients with advanced gastric cancer who were treated with nivolumab to monitor their disease progression and evaluate treatment response using serum inflammatory markers like CRP-to-albumin ratio (CAR), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR).
  • - Results indicated an overall response rate of 11.7% and a disease control rate of 44.1%, with median overall survival of 14 months and progression-free survival of 4.1 months.
  • - Changes in the inflammatory markers after therapy proved to be useful in predicting treatment response, with specific cutoff values identified for CAR, PLR, and NLR that correlated

Article Synopsis
  • - A new cell line called qMDCK-Cs was developed to isolate viruses for seasonal influenza vaccines, achieving over 70% efficiency when tested with clinical samples from influenza-positive patients.
  • - The isolated strains showed strong antigenic similarity to current vaccines, with 100% of some strains (like A/H1N1pdm09) matching criteria set by the World Health Organization for effectiveness.
  • - This method reduces the need for seasonal clinical sample collection and analysis, making it a more efficient approach for developing appropriate vaccine viruses.
