[Long-Term Survival in Esophagogastric Junction Cancer with Multiple Lymph Node Metastasis Through Pre-and-Post Operative Chemotherapy].

A 62-year-old man was diagnosed with Stage Ⅲ signet ring cell carcinoma of the lower thoracic esophagus. The patient underwent 2 courses of neoadjuvant cisplatin and 5-fluorouracil(SP therapy), demonstrating stable efficacy. Subsequently, the patient underwent subtotal esophagectomy with thoracoabdominal 2-field lymphadenectomy via right thoracotomy, followed by esophageal reconstruction using a gastric tube through a retrosternal route.

[Case of Long-Term Survival after Definitive Chemoradiotherapy for Unresectable Locally Advanced Esophageal Squamous Cell Carcinoma].

67-year-old woman underwent definitive chemoradiotherapy( dCRT) with cisplatin( CDDP) and 5-fluorouraci(l 5-FU)(FP) for locally advanced unresectable squamous cell carcinoma of the thoracic esophagus. During treatment, the patient developed grade 3 pharyngitis and esophagitis as adverse events. She was administered maintenance chemotherapy with 2 courses of FP and achieved complete response.

Simplified and Optimized Immune Score for Colorectal Cancer Microenvironment.

Background/aim: Immunoscore (IS) is an important evaluation method for the tumor immune microenvironment (TIME); however, formal IS analysis requires designated reagents and a specific digital pathology software and image data analysis. This study aimed to investigate whether simplified IS (s-IS) can substitute formal IS upon modifying the location of the assessment of the numbers of immune cells and verify that the addition of T cell subset markers to s-IS can enhance the prognostic impact in patients with colorectal cancer (CRC).

Patients And Methods: A total of 82 CRC cases were included in this study.

Observation of Histone H2AX Phosphorylation by Radiation-Induced Bystander Response Using Titanium Characteristic X-ray Microbeam.

Radiation-induced bystander response (RIBR) is a response induced in non-irradiated cells that receive bystander signals from directly irradiated cells. X-ray microbeams are useful tools for elucidating the mechanisms underlying RIBR. However, previous X-ray microbeams used low-energy soft X-rays with higher biological effects, such as aluminum characteristic X-rays, and the difference from conventional X-rays and γ-rays has often been discussed.

A Case of Immediate Anastomotic Leakage After Low Anterior Resection for Rectal Cancer.

A man in his seventies was referred to our hospital for radical therapy for advanced rectal cancer with multiple liver metastases. A colonic stent had already been placed in his rectum at the previous hospital because of malignant colorectal obstruction, so our therapeutic strategy was to perform systematic chemotherapy after resection of the primary tumor. Laparoscopic low anterior resection with a covering stoma was performed under general anesthesia.
