Wang L, Chen G, Jiang J. Cancer Manag Res. 2021;13:7365-7372. The authors have advised due to an oversight when writing the manuscript paraffin tissue extraction was missed from the Cervical Specimen Collection and HPV DNA Extraction section on page 7366. Page 7366, Cervical Specimen Collection and HPV DNA Extraction section, first sentence, the text "Samples of the uterine test-based uterus were collected from the collected cells" should read "Samples of the uterine test-based uterus were collected from the collected cells and paraffin sections". Page 7366, Cervical Specimen Collection and HPV DNA Extraction section, the following text should have been included before the last sentence of the section. The specimens of paraffin tissues were collected and DNA extracted as follows: paraffin tissues were cut into 4um thick slices, put into 1.5ml centrifuge tubes, added 150ul of lysis solution, shaken and mixed thoroughly, put into a metal bath and heated at 100 degrees for 10 minutes, and immediately centrifuged at 13000r/min for 10 minutes. The middle DNA solution was taken and used, and PCR amplification, hybridization, incubation and color development were standardized according to the instructions. The authors apologize for these errors.
