Similar conclusions were derived on other cancers, for instance Guo et al (2015) established a significant negative correlation between the KAI-1 mRNA expression and TNM stage in gastric cancer patients and Zhuo et al also reported a negative association between KAI-1 expression and clinical stage in cervical cancer patients (p<0.05) (Guo et al., 2015; Zhuo et al., 2015). This evidence concerns the gene CD82 and gastric cancer.
