Study Summary

Patients with cervical cancer that has not spread to other parts of the body can be cured with radiotherapy. One of the reasons radiotherapy can fail is because there are areas within the tumour that have a poor oxygen supply which makes them resistant to radiotherapy. This study aims to assess if it is feasible using special types of magnetic resonance imaging (MRI) - multi-parametric (MP) MRI to identify areas of low oxygen within the tumour so a higher dose of radiation can be given specifically to these areas to overcome the resistance and potentially improve cure rates without increasing side effects.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Histologically confirmed FIGO stage Ib2-IVa squamous, adeno or adenosquamous carcinomaof the cervix.
  • Clinically and/or radiographically documented measurable disease with at least onesite of disease unidimensionally measurable as per RECIST 1.1
  • All detectable disease including pelvic/para-aortic nodes encompassable within radicalhigh-dose radiation field
  • Deemed suitable and fit for radical chemoradiation
  • ECOG performance status 0 - 1
  • Aged 18 and over
  • Documented negative pregnancy test (if applicable)
  • Capable of providing written or witnessed informed consent according to ICH/GCP andnational/local guidelines prior to registration

Exclusion

Exclusion Criteria:

  • Previous pelvic malignancy (regardless of interval since diagnosis)
  • Previous malignancy not affecting the pelvis (except basal cell carcinoma of the skin)where disease free interval is less than 10 years
  • Evidence of distant metastasis i.e. any non-nodal metastasis beyond the pelvis
  • Previous pelvic radiotherapy
  • Prior diagnosis of Crohn's disease or Ulcerative colitis
  • Uncontrolled cardiac disease (defined as cardiac function which would precludehydration during cisplatin administration)
  • Previous record of allergic reaction to Gadolinium-based contrast media and any othercontra-indication to magnetic resonance imaging (MRI)
  • Any psychological, familial, sociological or geographical condition potentiallyhampering compliance with the study protocol and follow-up schedule; those conditionsshould be discussed with the patient before registration in the study
  • Participation in any interventional trials

Study Description

The study is an early exploratory study which will use MP MRI to predict which patients with locally advanced cervical cancer are likely to respond less well to chemoradiotherapy treatment, identify those patients and then intervene.

Hypoxia (deprivation of oxygen supply at tissue level) has long been shown to be a major cause of radiation resistance in various tumour sites and has been shown to be a harmful factor in cervical cancer and is associated with poor outcomes for patients. The aim of the study is to scan patients using different MP MRI sequences, each of which will measure different things, including blood flow, tumour necrosis and oxygen levels to determine hypoxia. This will be the first study to use the 3 different types of MRI scan (Diffusion Weighted - DWI, Dynamic Contrast Enhanced - DCE and Blood Oxygen Level Dependent - BOLD) at 3 different time points during the whole course of chemoradiotherapy.

The first scans will be prior to chemoradiotherapy treatment, the second set will be in week 2 and the final set in week 5. The imaging parameters from the MP MRI scans will be used as a surrogate markers of hypoxia. If high levels of hypoxia is identified using MP MRI, a prognostic imaging biomarker model can be developed to predict treatment outcomes of patients with locally advanced cervical cancer after chemoradiotherapy.

This study has potential to benefit all patients with locally advanced cervical cancer undergoing radical radiotherapy through the provision of more robust risk stratification. Improved risk stratification will result in more personalised treatment of better quality leading potentially to more cures and less side effects. As reported by Cancer Research UK, 3200 women are diagnosed with cervical cancer each year in the UK. 40% of these women are treated with radical radiotherapy, all of whom may benefit from the outputs of this study.
