<bold>Background</bold>: Our objective was to examine the associations between special AT-rich sequence binding protein 2 (SATB2) and chitinase-3-like protein-1 (CHI3L1) and the responsiveness to paclitaxel treatment in individuals with gastric cancer.
<bold>Methods</bold>: From March 2018 to October 2020, our hospital collected gastric cancer samples along with adjacent gastric mucosal tissues located more than 5 cm away from the cancerous margin. These samples were obtained from 90 patients who underwent chemotherapy regimens containing paclitaxel. To assess the rates of positive expression of CHI3L1 and SATB2 in gastric cancer and adjacent tissues, the immunohistochemical streptavidin-peroxidase (SP) technique was utilized.
<bold>Results</bold>: The positive expression rate of CHI3L1 was higher in gastric cancer tissues compared to adjacent tissues, while the positive expression rate of SATB2 was lower (P&lt;0.05). Risk factors that influenced the positive expression of CHI3L1 in gastric cancer tissues included the level of differentiation, tumor-node-metastasis (TNM) stage, and the presence of lymph node metastasis (OR>1, P&lt;0.05). Additionally, the positive expression of SATB2 was also affected by TNM stage and lymph node metastasis, which were identified as risk factors (OR>1, P&lt;0.05). In gastric cancer tissues, there was a negative correlation observed between the expressions of CHI3L1 and SATB2 (r&lt;0, P&lt;0.05). According to the analysis results of Kendall’s tau-b (K), it was found that the presence of CHI3L1 had an inverse relationship with the responsiveness to paclitaxel-based chemotherapy in gastric cancer (r=-0.498, P=0.000), while SATB2 exhibited a positive correlation with the sensitivity (r=0.513, P=0.000). During the 3-year follow-up after chemotherapy, the survival rate was 55.55% (50/90).

Results: The positive expression rate of CHI3L1 was higher in gastric cancer tissues compared to adjacent tissues, while the positive expression rate of SATB2 was lower (P1, P1, P<0.05). In gastric cancer tissues, there was a negative correlation observed between the expressions of CHI3L1 and SATB2 (r<0, P<0.05).
