Method for providing the information for prediction of lymph node metastasis of gastric cancer

摘要

The present invention relates to a method of providing information for predicting lymph node metastasis of gastric cancer, and in more detail, the maximum standard intake of primary cancer in F-18 FDG (fluoro-2-deoxyglucose) PET/CT (positron emission tomography/computed tomography) The present invention relates to a method of providing information for predicting lymph node metastasis of gastric cancer by combining the coefficient (T_SUVmax) and the maximum standard intake factor (N_SUVmax) of a lymph node with hematological information of a gastric cancer patient. In the present invention, the maximum standard intake coefficient (T_SUVmax) and the maximum standard intake coefficient (N_SUVmax) of the lymph nodes obtained from F-18 FDG PET/CT before surgery, and the tumor marker CA19-9 and albumin (Albumin) among hematologic indicators In this multivariate logistic regression analysis, it was confirmed that it was a statistically significant association factor in predicting lymph node metastasis. Finally, the area under the curve of the model made with the four parameters T_SUVmax, N_SUVmax, CA19-9, and Albumin; AUC) of 0.780 was confirmed to be the most suitable model for predicting lymph node metastasis of gastric cancer, and thus, information on whether or not lymph node metastasis of gastric cancer can be effectively provided using the above four parameters.
