[Current Status of ICG Fluorescence Navigation in Laparoscopic Liver Resection].

The indocyanine green(ICG)fluorescence navigation that we have standardized for laparoscopic liver resection is useful for partial liver resection and anatomical liver resection for liver cancer, and extended cholecystectomy for gallbladder cancer. In partial liver resection we believe that it is possible to secure a resection margin by not exposing the fluorescence emission around the tumor. In anatomical liver resection, real-time navigation becomes possible by transecting the liver at the boundary between colored and non-colored area, which contributes to precise liver surgery.

[Long-Term Survival of an Adolescent and Young Adult Patient with Unresectable Advanced Gastric Cancer in Whom Multidisciplinary Treatment Was Effective].

We report the case of a long-term-surviving adolescent and young adult patient with unresectable advanced gastric cancer for whom multidisciplinary treatment was effective. A 29-year-old woman was referred to our hospital for further examination following a diagnosis of gastric cancer by a local physician. Esophagogastroduodenoscopy showed a deep ulcerated lesion in the lower third of the stomach, and analysis of biopsy specimens revealed an adenocarcinoma.

[Brain Metastasis Arising from Gastric Cancer during Long-Term Treatment Using Nivolumab].

Metastasis to the central nervous system from gastric cancer is exceedingly uncommon. We report a gastric cancer patient with cerebral metastasis during the period when durable response was obtained by systemic drug treatment using nivolumab. A 78-year-old male was referred to our hospital for further examination following diagnosis of gastric cancer by a local medical doctor.

Laparoscopic total gastrectomy for concurrent gastric cancer and complete agenesis of the dorsal pancreas.

We present an unusual case of laparoscopic total gastrectomy with lymph node dissection in a 56-year-old woman with gastric cancer and agenesis of the dorsal pancreas (ADP). Esophagogastroduodenoscopy revealed erosive lesions with thickened gastric folds; biopsy specimens revealed a poorly differentiated adenocarcinoma. Abdominal contrast-enhanced computed tomography showed a thickened wall of the gastric body; the distal pancreas was not visualized.

Methods: A total of 419 patients diagnosed with unresectable advanced or recurrent gastric cancer at Kochi Medical School between January 2007 and December 2021 were evaluated. Data of patients were reviewed, and clinicopathological information and survival outcomes of those with CNS metastases were compared to patients without CNS metastases.

Frequency and therapeutic strategy for patients with ovarian metastasis from gastric cancer.

Purpose: This study aimed to analyze the clinicopathological features and treatment outcomes of ovarian metastasis from gastric cancer.

Methods: This study included 155 female patients with unresectable advanced or recurrent gastric cancer at the Kochi Medical School between January 2007 and December 2021. A review of patients with ovarian metastasis was conducted, and their clinicopathological information and survival outcomes were compared with respect to ovarian metastasis.

Pneumothorax during lenvatinib treatment for hepatocellular carcinoma with lung metastasis.

Lenvatinib is an inhibitor of tyrosine kinases, such as vascular endothelial growth factor receptor and fibroblast growth factor receptor, and was first approved for use in thyroid cancer in 2015 in Japan. Additional approval was given in March 2018 for its use as a first-line treatment for advanced or unresectable hepatocellular carcinoma. Herein, we report a case of pneumothorax during lenvatinib treatment for multiple lung metastases of hepatocellular carcinoma in a 71-year-old man.

Lymph node retrieval after colorectal cancer surgery: a comparative study of the efficacy between the conventional manual method and a new fat dissolution method.

Purpose: This study compared the efficacy of two different methods for lymph node (LN) searching after colorectal cancer surgery: the fat dissolution and the conventional manual method.

Methods: For the fat dissolution method, we used a commercially available solution of collagenase and lipase (FD group). The primary endpoint was the number of identified LNs in the FD group compared to an historical control (control group) after adjusting by propensity score matching.

Data on metabolic profiling of healthy human subjects' plasma before and after administration of the Japanese Kampo medicine maoto.

This data article contains the data on metabolic profiling of healthy human subjects' plasma before and after administration of the Japanese Kampo medicine maoto. Four healthy human subjects were recruited. Plasma samples were collected before and 0.

Phenotyping analysis of the Japanese Kampo medicine maoto in healthy human subjects using wide-targeted plasma metabolomics.

Traditional herbal medicine (THM) consists of a vast number of compounds that exert pharmacological effects throughout the body. Comprehensive phenotyping analysis using omics is essential for understanding the nature of THM in detail. We previously reported that the Japanese Kampo medicine maoto ameliorated flu-like symptoms in a rat infection model and dynamically changed plasma metabolites as indicated by metabolome analysis.

Serum carbohydrate antigen 125 is a significant prognostic marker in patients with unresectable advanced or recurrent gastric cancer.

Purpose: We evaluated the diagnostic and prognostic value of three tumor markers: carcino-embryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and carbohydrate antigen 125 (CA125), in the pretreatment serum of patients with unresectable advanced or recurrent gastric cancer.

Methods: The subjects of this retrospective analysis were 245 patients with unresectable advanced or recurrent gastric cancer diagnosed at Kochi Medical School between 2007 and 2015. We ascertained the sensitivity of CEA, CA19-9, and CA125 to identify a certain survival time and then evaluated the relative prognosis of the patients.

Metachronous solitary splenic metastasis arising from early gastric cancer: a case report and literature review.

Background: The metastasis of malignant tumors to the spleen is rare, and only a small percentage of cases can be treated surgically, as splenic metastases generally occur in the context of multivisceral metastatic cancer at a terminal stage. We report a rare case of metachronous solitary splenic metastasis arising from early gastric cancer.

Case Presentation: A 75-year-old man was initially referred to our hospital for examination of gastric cancer, diagnosed at a medical check-up.

Gastric adenocarcinoma at the anastomotic site 50 years after gastrojejunostomy: A case report.
