Quantification of tumor regression, Set-up errors and Internal Organ Motion in locally advanced Cervical cancer treated with radical radiation - results from a prospective study

➢ Cervical cancer with intact Uterus

N = 67

➢ N = 70 patients with FIGO IIB-IIIB (3 out of trial)

➢ May 2011- March 2017

➢ Daily CBCT- IGRT (3DCRT/IMR plan)

➢ Online/Offline: CTV nodal/primary mid-cervix and uterine matching

➢ Baseline MRI and Mid-RT MRI = To evaluate tumor Regression

Mean cervical tumor volume reduced from 55.2 cc at diagnosis to 28.9 cc at mid treatment.
