Corrigendum

Corrigendum to Knockdown of ubiquitin-specific protease 53 enhances the radiosensitivity of human cervical squamous cell carcinoma by regulating DNA damage-binding protein 2. Technology in Cancer Research and Treatment 19(1): 1–7. DOI: 10.1177/1533033820929792

On P. 3 in Results section, paragraph 2 should be read as follows:

After a period of regular radiotherapy and chemotherapy, the curative effect (SD, PR, CR) is evaluated by the clinician based on the test results and clinical symptoms.

On P. 4, Table 2 should be read as follows:
