Pancreatic ductal adenocarcinoma (PDAC) is a lethal cancer type as it is prone to metastases and is difficult to diagnose at an early stage. Despite advances in molecular detection, its clinical prognosis remains poor and it is expected to become the second leading cause of cancer-related deaths. Approximately 85% of patients develop glucose metabo...

Background
Preoperative treatment is performed for locally advanced colon cancer with extensive tumor proximity or suspected invasion of skeletal muscles, major organs, and blood vessels. Oxaliplatin-based regimens are often used in preoperative chemotherapy. However, microsatellite instability (MSI)-high colorectal cancer is often resistant to cyt...
Fibroblast activation protein (FAP) generally shows low or undetectable expression in most normal tissues but is highly expressed in fibroblasts in almost all carcinomas. FAP is one of the potential molecules to detect activated fibroblasts and has multiple roles in tumour progression. We generated transgenic mice that specifically expressed tdToma...
Excess stroma and cancer-associated fibroblasts (CAFs) enhance cancer progression and faciliate immune evasion. Insights into the mechanisms by which the stroma manipulates the immune microenvironment could help improve cancer treatment. Here, we aimed to elucidate potential approaches for stromal reprogramming and improved cancer immunotherapy. Pl...

Background:
Immune checkpoint inhibitors (ICIs) are increasingly being used for the treatment of upper gastrointestinal cancers [esophageal cancer and gastric cancer (GC)]. They cause imbalances in immunological tolerance, resulting in immune-related adverse events (irAEs). Although irAEs have been reported to be associated with the efficacy of IC...
Background
Remodeling the tumor microenvironment (TME) to benefit cancer cells is crucial for tumor progression. Although diffuse-type gastric cancer (DGC) preferentially interacts with the TME, the precise mechanism of the complicated network remains unknown. This study aimed to investigate the mutual activation mechanism underlying DGC progressio...
Background:
Hyperglycaemia is a well-known initial symptom in patients with pancreatic ductal adenocarcinoma (PDAC). Metabolic reprogramming in cancer, described as the Warburg effect, can induce epithelial-mesenchymal transition (EMT).
Methods:
The biological impact of hyperglycaemia on malignant behaviour in PDAC was examined by in vitro and i...
Introduction
Pancreatic ductal adenocarcinoma (PDAC) is characterized by abundant stroma and cancer-associated fibroblasts (CAFs) provide a favorable tumor microenvironment. Smad4 is known as tumor suppressor in several types of cancers including PDAC, and loss of Smad4 triggers accelerated cell invasiveness and metastatic potential. The thrombospo...
Background:
Experimental studies suggest that self-expanding metal stents (SEMSs) enhance the aggressive behavior of obstructive colorectal cancer. The influence of SEMS placement on pathological alterations remains to be elucidated.
Aim:
To determine whether SEMS placement is associated with molecular or pathological features of colorectal carc...
Since the advent of immune checkpoint inhibitors, which modulate the interplay between the tumor cell and immune system, immunotherapy has become widely recognized as a new standard treatment for cancers including microsatellite instability‐high (MSI‐H) colorectal cancer. Immune checkpoint inhibitors such as pembrolizumab and nivolumab (anti‐PD‐1 a...

Background
Esophagectomy for esophageal cancer is associated with frequent respiratory morbidities, which may deteriorate postoperative survival outcomes. Thoracoscopic esophagectomy (TE) is less invasive and is associated with fewer respiratory morbidities than open esophagectomy. However, the relationship between post-TE respiratory morbidity and...
Bone marrow (BM)-resident hematopoietic stem and progenitor cells (HSPCs) are often activated following bacterial insults to replenish the host hemato-immune system, but how they integrate the associated tissue damage signals to initiate distal tissue repair is largely unknown. Here, we show that acute gut inflammation expands HSPCs in the BM and d...
Background:
Anastomotic leakage after esophagectomy remains frequent and can cause surgery-related mortality. Wrapping the esophago-conduit anastomosis with a greater omental flap is a proposed method to reduce leakage. However, the usefulness of omental wrapping (OW) has not been elucidated.
Methods:
This study included 338 patients with esopha...
Background:

We examined the expression of HLA-E on GC cells and soluble HLA-E under...
Accumulating evidence suggests that high levels of Fusobacterium nucleatum (F. nucleatum) in colorectal tumor tissues can be associated with poor prognosis in patients with colorectal cancer (CRC); however, data regarding distinct prognostic subgroups in F. nucleatum-positive CRC remain limited. Herein, we demonstrated that high iron status was ass...

Background
Several cohort studies have reported that post-esophagectomy morbidities may worsen prognosis. Smoking cessation is an effective prophylactic measure for reducing post-esophagectomy morbidity; however, whether smoking cessation can contribute to the improvement of prognosis is unknown due to the absence of reliable databases covering the...
PurposePreoperative malnutrition is a significant risk factor for post-esophagectomy morbidity. The Controlling Nutritional Status (CONUT) is an index used to assess nutritional status, and it has been suggested to predict post-esophagectomy morbidity. However, the difference in the predictive value of CONUT in estimating morbidities between open e...
Uncontrolled proliferation of intestinal epithelial cells caused by mutations in genes of the WNT/β-catenin pathway is associated with development of intestinal cancers. We previously reported that intestinal stromal cell-derived angiopoietin-like protein 2 (ANGPTL2) controls epithelial regeneration and intestinal immune responses. However, the rol...

It is difficult to fabricate three-dimensional structures using semiconductor-process technology, because it is based on two-dimensional layered structure fabrication and the etching of thin films. In this study, we fabricated metal structures that can be dynamically deformed from two-dimensional to three-dimensional shapes by combining patterning...
Background:
Although PNENs generally have a better prognosis than pancreatic cancers, some PNENs display malignant behavior including lymph node (LN) metastasis. Complete tumor resection can be the only potentially curative treatment for patients with resectable PNENs. However, the indications for LN dissection are still controversial. Over the la...
Prediction of hepatocellular carcinoma (HCC) risk is an urgent unmet need in patients with nonalcoholic fatty liver disease (NAFLD).

Background:
Sarcopenia is associated with poor prognosis in patients with colorectal cancer (CRC), but the mechanisms contributing to this association remain unclear. We hypothesized that skeletal muscle status is associated with tumor-infiltrating lymphocytes (TILs) in patients with CRC. Therefore, this study investigated the clinical effect of s...
Aim:
Oncologic emergencies such as perforation and obstruction associated with colorectal cancer are serious diseases that can lead to sepsis. Peritoneal dissemination and other factors may cause cancer progression and worsen the patients' long-term prognosis. In this study, we investigated the effect of colorectal cancer presenting as oncologic e...
Purpose
High preoperative hemoglobin A1c (HbA1c) levels have been suggested to increase complications after esophagectomy. Minimally invasive esophagectomy (MIE) is less invasive than open esophagectomy (OE) and may reduce postoperative complications.
