Peritoneal metastasis (PM) remains a major challenge in patients with gastric cancer (GC) and occurs preferentially in adipose-rich organs, such as the omentum. Adipose-derived stem cells (ASCs) may influence cancer behavior. This study aimed to investigate whether ASCs isolated from the omentum can act as progenitors of cancer-associated fibroblasts (CAFs) and analyze their effects on the cancer stem cell (CSC) niche and the treatment resistance of GC cells.

We investigated the potential role of hemocytes in induction in tumor-bearing mutants via immunostaining and RNAi experiments. Normal hemocytes transplanted into mutant larvae were recruited to the tumor and fat body (FB), suggesting that these cells transmit tumor-related information.

The prognosis of patients with MiNEN is poor because of the high frequency of recurrence and metastases. We report a case of esophagogastric junction MiNEN (EGJ-MiNEN) with a long-term recurrence-free survival of 5.

This phenomenon is known as the senescence‑associated secretory phenotype (SASP). SASP in cancer stromal fibroblasts is involved in cancer growth and progression.

This study aimed to describe the perioperative outcomes of 12 patients who underwent robotic gastrectomy for gastric cancer using the hinotori™ surgical robot system (hinotori), a novel robot-assisted surgical platform, and compare the outcomes with the existing system, the da Vinci Surgical System (DVSS). This study included 12 consecutive patients with gastric cancer who underwent robotic gastrectomy for gastric cancer using the hinotori between March 2023 and September 2023 at our institution.

Although it is well known that there are differences of sensitivity between species in the pseudo-allergic reactions, no platform for evaluating a human risk of the pseudo-allergic reactions observed in nonclinical studies has been established. Valemetostat tosylate, developed as an anti-cancer drug, induced histamine release in a nonclinical study with dogs.

This study analyzed the effect of risk factors, such as the degree of arteriosclerosis, comorbidities, and patient characteristics on the incidence of reconstruction-related complications including anastomotic leakage. Furthermore, the usefulness of tailor-made reconstruction methods was clarified using wide gastric conduit.

The parents of 160 children with ASD (male, n = 123; female, n = 37) were recruited from two hospitals in K and H cities, and as a control group, 145 children (male, n = 75; female, n = 70) were recruited from four nursery schools in T city. The associations between ASD and bedtime and waking time on weekdays and weekends in infancy (<1 years of age), at 1-3 years, and at 3-5 years of ages were studied using a multivariable logistic regression analysis.

The role of the lipoxygenase (LOX) pathway in carcinogenesis has been recently reported; however, its involvement in esophageal carcinogenesis remains unclear. To address this, the present study investigated the potential of pranlukast, a cysteinyl leukotriene receptor-1 antagonist, to suppress the progression of BE and EAC in a rat duodenogastroesophageal reflux (DGER) model.

Total resection of the gastric tube is expected to be curative for patients with GTC. However, several studies have reported that this procedure is associated with high mortality and morbidity rates.

We explored the prevalence of GI and GU symptoms and their impact on quality of life (QOL) in people with FSHD compared to healthy household controls.
Methods: In this descriptive, cross-sectional study, we emailed a survey exploring GI and GU symptoms to all FSHD Society patient contacts (n = 3507).
Introduction: Evocalcet is an oral calcimimetic agent with proven efficacy and safety in treating secondary hyperparathyroidism (SHPT) in Japanese patients on dialysis.
Methods: This randomized, double-blind, intrapatient dose-adjustment, parallel-group, international multicenter study compared the efficacy and safety of evocalcet versus cinacalcet for 52 weeks in East Asian hemodialysis patients with SHPT.
Results: In total, 203 and 200 patients were randomized to receive evocalcet or cinacalcet, respectively (overall, 70.
Introduction: Serum phosphorus management is important for patients with chronic kidney disease on dialysis to reduce the risk of hyperparathyroidism and ectopic vascular calcification. Phosphate binders (PBs) control serum phosphorus levels; however, some patients do not achieve adequate control with existing PBs. The similar mechanisms of action of each PB may limit their ability to lower serum phosphorus levels.

However, the malignant nature of these cells remains unknown. We aimed to identify if mxc LG cells behave as malignant tumor cells and uncover the mechanism(s) underlying the malignancy of the mutant hemocytes.

This study aimed to identify the anatomical factors associated with the difficulty of minimally invasive esophagectomy assessed by intraoperative injuries and postoperative outcomes.
Methods: Minimally invasive esophagectomy in the left-decubitus position was performed in 258 patients.
Background: Malignant esophageal stenosis is a common and severe complication of advanced esophageal cancer that can be a serious problem in the continuation of chemotherapy and other anticancer treatments. The impact of chemotherapy regimens on the degree of improvement in esophageal stenosis is unknown. In this study, we focused on the impacts of chemotherapy on the direct anticancer effects, and in the improvement of malignant stenosis.

We report a very rare case of jejunal necrosis caused by NOMI in the pedicled mesentery of the reconstructed jejunum after remnant gastric tube resection for heterochronous gastric tube cancer after esophagectomy.
Case Presentation: An 80-year-old man visited our department with chief complaints of fever and appetite loss after 4 months from gastric tube resection and digestive reconstruction with pedicled jejunum.
Introduction: Endoscopic submucosal dissection (ESD) allows the en bloc resection of colorectal epithelial tumors regardless of size. Although ESD is minimally invasive and yields favorable outcomes, it is technically difficult and requires a long procedure time. In addition, colorectal ESD is associated with a particularly high risk of complications, due to the thin bowel wall, bowel flexion, and peristalsis.
