Spectral CT Combined With MSI for Predicting Regional Lymph Node Metastasis in Gastric Cancer

Spectral CT Combined With MSI for Predicting Regional Lymph Node Metastasis in Gastric Cancer

This study prospectively collected spectral CT imaging data and clinical information related to gastric cancer, evaluated the diagnostic efficacy of its image quality for regional lymph nodes in gastric cancer, and explored its application value in the N staging of gastric cancer with different MSI statuses, so as to provide a more accurate evidence for clinical diagnosis, promote the development of individualized treatment for gastric cancer, and ultimately improve the prognosis of patients.

Inclusion Criteria:

• (a)Patients with gastric adenocarcinoma confirmed by histopathological biopsy and definite microsatellite status determined by immunohistochemistry (IHC);
• (b)Abdominal dual-phase Quark CT scanning was performed within 2 weeks before surgery;
• (c)aged ≥ 18 years old

Exclusion Criteria:

• (a)Combined with other primary tumors;
• (b) The image quality does not meet the diagnostic criteria;
• (c)Those who cannot tolerate CT examination.
