Prognostic value of systemic inflammation score in patients with esophageal cancer.

Introduction: The systemic inflammatory score (SIS), a new inflammatory marker based on a combination of the lymphocyte-to-monocyte ratio (LMR) and serum albumin concentration, has been reported to be a useful prognostic marker for several malignancies. The authors conducted this retrospective study on data from a cohort of esophageal cancer patients undergoing potentially curative resection to clarify the value of SIS as a prognostic marker for clinical outcome in this population.

Methods: This retrospective cohort study included 32 patients who underwent thoracoscopic esophagectomy after neoadjuvant chemotherapy for esophageal cancer between January 2016 and December 2019.

Primary Malignant Melanoma of the Esophagus Treated with Surgical Resection at an Early Stage.

Introduction: Primary malignant melanoma of the esophagus is a very rare disease with a poor prognosis. We herein report a patient with primary malignant melanoma of the esophagus who underwent surgical resection.

Case Presentation: A 73-year-old female underwent an upper gastrointestinal endoscopy during follow-up for colonic diverticulitis.

[A Case of Advanced Rectal Cancer Successfully Treated with Preoperative Radiochemotherapy].

An 80-year-old woman who visited our hospital with chief complaints of decreased appetite and diarrhea. Lower gastrointestinal endoscopy showed a type 2 tumor in the rectal Ra, and biopsy revealed a well-differentiated adenocarcinoma. The patient had locally advanced rectal cancer with widespread contact with the sacrum, and preoperative radiochemotherapy (S-1 100 mg/day plus radiotherapy 50 Gy/25 Fr)was performed.

[A Resected Case of Leiomyosarcoma Originating from the Ovarian Vein].

We present a 46-year-old female patient who underwent resection of a retroperitoneal tumor, which was found by medical check-up. The tumor which was elastic hard and had good mobility displaced the duodenum to her abdominal wall. Since her right ovarian vein adhered to the tumor, we removed the tumor with the ligated vein.

Subtotal gastrectomy for gastric tube cancer using intraoperative indocyanine green fluorescence method.

Introduction: Currently, the frequency of evaluating the flow of a reconstructed gastric tube using indocyanine green (ICG) fluorescence has been increasing. However, it has been difficult to decide on the operation method for patients with gastric tube cancer (GTC). We herein report a case in which ICG was effective in a patient with resection of GTC.

[A Case of Small Cell Carcinoma of the Pancreas].

A 55-year-old man was admitted to our hospital for jaundice. Magnetic resonance cholangiopancreatography showed a mass in the pancreatic head as well as biliary obstruction. We strongly suspected invasive ductal carcinoma of the pancreas.

[A Clinical Study of Seven Cases of LECS for Gastric Submucosal Tumors].

Laparoscopy and endoscopy cooperative surgery(LECS)is a surgical technique to resect a tumor with minimal invasion, using both a laparoscope and endoscope. Twenty-eight surgeries for gastric submucosal tumors(SMT)were performed between 2009 and 2019. Seven of those cases were performed using LECS.
