Imaging in Cervix Cancer – Dr Sarah Swift, St James’s Hospital, Leeds, UK
Imaging plays a crucial role in the management of women with cervical cancer. Stage of disease has a profound effect on the treatment options available and the use of magnetic resonance imaging (MRI) has improved staging accuracy. MRI is routinely used in the assessment of women with cervix cancer for staging the primary tumour, assessing prognostic factors such as tumour size and lymph node status and triaging patients to surgical or non-surgical management. Its high negative predictive value for parametrial invasion makes it useful for selecting surgical candidates.
The limitations of MRI in assessing nodal disease have been helped by the addition of PET/CT to the assessment of patients with advanced cervix cancer and this has improved detection of nodal metastases. The positive predictive value of PET/CT is high enough to modify treatment strategy. In patients undergoing non-surgical management with chemo-radiotherapy, MRI guided intracavitary brachytherapy allows accurate delineation of residual tumour volumes. Imaging is also vital post primary therapy to assess treatment response, suspected relapse and the development of complications.
