As summarized in Table 1, expression of PTRF in colorectal cancer tissues was negatively correlated with the TNM stage (p = 0.0179) and histologic stage (p = 0.0443), but was not related to other clinicopathological characteristics, such as age (p = 0.901), gender (p = 0.817), or disease localization (p = 0.923). The gene discussed is CAVIN1; the disease is colorectal cancer.
