The value of adding a single co-test in HPV primary screening.

Prev Med 2021 May 10:106617. Epub 2021 May 10.

Department of Laboratory Medicine, Faculty of Medicine and Health, Örebro University, Örebro, Sweden.

The screening program for cervical cancer in Sweden, recommends screening with HPV test primarily for women over 30 years, but at the first screening test that is performed after the age of 40, both HPV test and cytology is recommended, so-called co-testing. The aim of this study was to examine how many cases of HPV negative cervical dysplasia that were found in this age-group, to be able to estimate the value of adding a co-test in an HPV screening program. A retrospective study of all abnormal cytological samples found in the cytology based screening program in the age group 41-45 years during the years 2012-2016 in the Region of Örebro County was performed.

Indocyanine green versus technetium-99m with blue dye for sentinel lymph node detection in early-stage cervical cancer: A systematic review and meta-analysis.

Cancer Rep (Hoboken) 2021 May 11:e1401. Epub 2021 May 11.

Department of Gynecologic Oncology, Division of Imaging and Oncology, University Medical Center Utrecht, Utrecht University, Utrecht, The Netherlands.
