Field carcinogenesis and biological significance of the potential of the bystander effect: carcinogenesis, therapeutic response, and tissue regeneration.

The "bystander effect" is a transmission phenomenon mediating communication from target to non-target cells, as well as cell-to-cell interactions between neighboring and distantly located cells. In this narrative review, we describe the fundamental and clinical significance of the bystander effect with respect to cell-to-cell interactions in carcinogenesis, therapeutic response, and tissue regeneration. In carcinogenesis, the bystander effect mediates communications between tumor microenvironments and non-malignant epithelial cells and has been suggested to impact heterogeneous tumorigenic cells in tumors and cancerized fields.

Idiopathic pneumoperitoneum diagnosed following high-energy motor vehicular trauma:a case report.

Intra-abdominal free gas is a finding of extra-intestinal gas in the abdominal cavity on radiography or CT, mainly suggesting gastrointestinal perforation and necessitating emergency surgery. Idiopathic pneumoperitoneum is diagnosed when there is no obvious gastrointestinal perforation, but there is presence of free gas in the abdominal cavity with an unidentifiable cause. Herein, we report a case of idiopathic pneumoperitoneum secondary to high-energy trauma following a car rollover accident.

ASO Author Reflections: Impact of the Ratio of the Visceral Fat Area (VFA) to Psoas Muscle Area (PMA) (V/P Ratio) on Survival for Patients with Surgically Resected Esophageal Cancer.

PAST: The true impact of co-occurring muscle mass reduction and fat accumulation on patients with surgically resected esophageal cancer (EC) remains controversial. PRESENT: The current study defined reduction in muscle mass and excess body adiposity as the ratio of the visceral fat area (VFA) to the psoas muscle area (V/P ratio) on the same axial computed tomography slice at the third lumbar vertebra (L3). A high V/P ratio was associated with greater age (p = 0.

Impact of the Ratio of Visceral Fat Area (VFA) to Psoas Muscle Area (PMA) (V/P Ratio) on Survival for Surgically Resected Esophageal Cancer.

Background: The synergic effects of muscle mass reduction with excess body adiposity in surgically resected esophageal cancer (EC) patients remains controversial, especially in non-obese patients.

Methods: One hundred and six patients with EC who underwent surgery between 2006 and 2014 were included in this study. Reduction in muscle mass and excess body adiposity were defined as the ratio of visceral fat area (VFA) to psoas muscle area (PMA) (V/P ratio) on the same axial computed tomography (CT) slice at the third lumbar vertebra (L3).

Salvage thoracoscopic esophagectomy after carbon-ion radiotherapy in a patient with esophageal squamous cell carcinoma: a case report.

Background: Carbon-ion radiotherapy (CIRT) for esophageal cancer has been receiving significant attention given its high local control rates and minimal damage to normal tissues. However, the efficacy and safety of salvage surgery after CIRT for esophageal cancer remain unclear. We report the case of a patient who underwent salvage thoracoscopic surgery after CIRT.

Impact of the Hepatic Branch of the Vagus Nerve Transection in Laparoscopic Sleeve Gastrectomy for Patients with Obesity and Type 2 Diabetes Mellitus.

Background: An increase in gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG) has been reported, and concomitant hiatal hernia repair (HHR) during LSG is expected to reduce the incidence of post-LSG GERD. In HHR, the hepatic branch of the vagus nerve is anatomically transected. Recent experimental animal models suggest that vagotomy may affect glycemic control and weight loss through a neuroendocrine response.
