In cervical cancer (Table 2), DAPK gene hypermethylation was more frequently detected in squamous cell carcinoma (SCC) than in adenocarcinoma (AC) (63.3% versus 34.5%, P = 0.006), whereas, PTEN was more frequently detected in AC than in SCC (34.5% versus 10.2%, P = 0.002). Here, PTEN is linked to cervical cancer.
