Endoscopic biopsy is essential to the proper diagnosis and treatment of gastric cancer. Unfortunately, the results of endoscopic biopsy are not always the same as what is expected based on gross endoscopic findings. The results of endoscopic biopsy can be negative for malignancy in Borrmann type IV advanced gastric cancer (AGCa) or gastric lymphoma. However, in the case of type II AGCa, repeated biopsies negative for malignancy have not been reported. A 49-year-old male patient underwent esophagogastroduodenoscopy three times due to large gastric ulcer suspected to be Borrmann type II cancer. However, three repeat endoscopic biopsies with multiple specimens showed necrosis and superficial regenerative epithelium without malignant findings. The patient underwent laparoscopic distal gastrectomy with D2 lymph node dissection. The surgical specimen revealed that the mucosal layer was completely replaced with regenerative epithelium without cancer cells.

Diffusion-weighted MRI of advanced gastric cancer: correlations of the apparent diffusion coefficient with Borrmann classification, proliferation and aggressiveness.
Abdom Radiol (NY)
January 2025
Department of Medical Imaging, Tongji Hospital, Tongji University, No. 389, Xincun Road, Putuo District, Shanghai, 200065, China.
Objectives: This study aimed to compare apparent diffusion coefficient (ADC) values derived from diffusion-weighted imaging (DWI) of different Borrmann types of advanced gastric cancer (AGC) and correlate these ADC values with Ki-67 expression and serum CEA levels in AGC.
Methods: A total of 84 patients with AGC who underwent DWI of the upper abdomen before tumor resection in our hospital between June 2014 and July 2018 were included in the present study. DWI was obtained with a single-shot echo planar imaging sequence in the axial plane (b values: 0, 100, 700 and 1000 s/mm).

Background: Different anesthetic drugs and techniques may affect survival outcomes for gastric cancer (GC) after surgery. In this study, we investigated the association between sedated and unsedated gastroscopy on survival outcomes in patients with GC after surgery.
Methods: This was a retrospective study of patients who were diagnosed with GC by gastroscopy and underwent gastrectomy from January 2013 to December 2017.
Risk factors and prognostic analysis of microscopic positive esophageal margins after radical surgery for proximal gastric cancer.

Background: Proximal gastric cancer has been on the rise worldwide in recent years. A positive surgical margin may result in incomplete tumor and affect the prognosis of patients. This study aims to analyse the risk factors for and prognosis associated with microscopic positive esophageal margins (R1 resection) after radical surgery for proximal gastric cancer patients.

Article Synopsis
- This study compares early-onset gastric carcinoma (EOGC) and late-onset gastric carcinoma (LOGC) by looking at trends, patient demographics, clinical features, and treatment outcomes at a major cancer center in China.
- The research aims to identify differences between EOGC and LOGC regarding patient characteristics and disease progression, in order to recommend better screening strategies.
- Findings suggest that while EOGC is more common in younger patients and has distinct clinical features, it exhibits higher rates of metastasis and quicker progression in later stages despite a better early prognosis, highlighting the need for targeted treatment approaches.
Assessment of Endoscopic Ultrasound for Predicting Preoperative T Staging in Patients With Gastric Adenocarcinoma.

Article Synopsis
- Endoscopic ultrasound (EUS) is being evaluated for its effectiveness in predicting tumor stage (T-stage) before surgery for gastric adenocarcinoma, specifically to determine suitable treatment options like endoscopic therapy or neoadjuvant therapy.
- A retrospective study at Taichung Veterans General Hospital included patients who underwent gastrectomy after preoperative EUS, revealing that EUS had moderate accuracy, especially being highly effective in predicting T1-stage tumors (85.23% accuracy), but less so for more advanced stages.
- The study concluded that while EUS is reliable for identifying T1-stage tumors appropriate for endoscopic treatment, it needs to be supplemented with additional methods for accurately predicting more advanced stages (T3 and above).
