ACTA1 and neoplasm: Compared to the THBS4-low expression in stroma, THBS4-high expression in stroma was significantly associated with higher αSMA expression, macroscopic type 4 (p<0.001), greater tumor diameter (p<0.001), diffuse-type histology (p<0.001), microscopic undifferentiated-type, higher tumor invasion (p<0.001), lymph node metastasis (p<0.001), lymphatic invasion (p<0.001), peritoneal cytology (p<0.001), and peritoneal metastasis (p<0.001).
