MRI-based volumetric tumor regression parameters (regression rate or area under regression curve) predicts long-term local tumor control and survival in cervical cancer. If tumor shows >10% residual volume at the conclusion of treatment, the risk for local failure and death are so high (> 80%) that aggressive intervention is warranted.
