To analyze the correlation between tumor deposition near gastric cancer and CT imaging features, serum indexes and pathological features.

A total of 93 patients with gastric cancer diagnosed by pathological examination in Jiulongpo District People's Hospital of Chongqing from January 2020 to January 2023 were selected and divided into positive group and negative group according to their tumor deposition. The differences of CT imaging features, serum indexes and pathological features between the two groups were compared, and the relationship between the above features and tumor deposition was evaluated by Logistic multivariate regression analysis.

Among 93 patients, 26 patients were found with tumor deposition, and the positive rate of tumor deposition was 27.96%. There was statistically significant difference between the positive group and the negative group in imaging staging and enhancement characteristics of venous phase (P<0.05). There was statistically significant difference in serum CEA between the positive group and the negative group (P<0.05). There were statistically significant differences between the positive group and the negative group in pathological stages and vascular invasion characteristics (P<0.05). Logistic multivariate regression model analysis showed that imaging stage T_3-4, pathological stage N₃ and vascular invasion were independent risk factors for tumor deposition (P<0.05).

Some patients with gastric cancer have tumor deposition near cancer, and higher imaging staging, pathological staging and vascular invasion may be related to tumor deposition.
