TERT and esophageal squamous cell carcinoma: A significantly decreased risk of ESCC associated with the TERT-CLPTM1L rs401681 C>T polymorphism was evident among male patients (CT vs CC: P = 0.0003; CT/TT vs CC: P = 0.0002), younger patients (<63 years in our study) (CT/TT vs CC: P = 0.049) and patients who were in drinking status (CT vs CC: P = 0.012; CT/TT vs CC: P = 0.016) (Table 3).
