Two Stage Segmentation of Cervical Tumors using PocketNet

no code implementations17 Sep 2024 Awj Twam, Megan Jacobsen, Rachel Glenn, Peng Wei, Jia Sun, Ann Klopp, Aradhana M. Venkatesan, David Fuentes

Cervical cancer remains the fourth most common malignancy amongst women worldwide. 1 Concurrent chemoradiotherapy (CRT) serves as the mainstay definitive treatment regimen for locally advanced cervical cancers and includes external beam radiation followed by brachytherapy. 2 Integral to radiotherapy treatment planning is the routine contouring of both the target tumor at the level of the cervix, associated gynecologic anatomy and the adjacent organs at risk (OARs).
