Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patients with locally advanced cervical cancer (LACC) are primarily treated with radiotherapy +/- chemotherapy however 5-year survival rates are \<60% with significant treatment toxicity. Hypoxia is a well-known radioresistant component of solid tumours such as cervical cancer and hypoxia modification therapies have demonstrated immense promise in treating such tumours. A major factor in determining a successful outcome with hypoxia modification is appropriate patient selection as it is hypoxic tumours that receive the most benefit from hypoxia modifying therapies. To date there is no validated hypoxia biomarker to stratify patients for therapy in cervical cancer in clinical use. This project offers a unique opportunity to examine both genetic and imaging biomarkers to optimise patient stratification when receiving curative radiotherapy for cervical cancer.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Locally advanced cervical cancer patients treated with standard of care chemoradiation

Biopsy of tumour

Intervention Type PROCEDURE

Cervical tumour biopsy during treatment. This will be used for gene expression (RNA) analysis against a hypoxia associated gene signature.

MRI scans

Intervention Type DIAGNOSTIC_TEST

Multiple magnetic resonance imaging (MRI) scans before and during treatment using oxygen enhanced (OE) / tissues oxygen level dependent (TOLD) sequence

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients must have a histologically confirmed diagnosis of cervical cancer
* Diagnostic/pre-treatment biopsy available
* Patients must be suitable for standard radiotherapy and brachytherapy
* Age greater than or equal to 18 years; no upper age limit
* Performance status - ECOG 0-2 (Refer to appendix 1)
* Women of childbearing age MUST have a negative pregnancy test prior to study entry and be using an adequate contraception method
* Before participant registration, written informed consent must be given according to GCP and national regulations.

Exclusion Criteria

* Participants deemed unsuitable for a biopsy (during or following radiotherapy) in the opinion of the treating oncologist.
* Patients with cardiac pacemakers, cochlear implants, intraocular foreign bodies or any other MR contraindication
* Patients with a hip replacement
* Patients with a known history of allergic reaction to gadolinium-based contrast agent
* Any contraindications to Hyoscine Butylbromide (Buscopan)
* Any patient taking ACE inhibitors. These should be stopped/substituted or they are a contraindication.
* Evidence of impaired renal function (eGFR \<15 ml/min)
* Any evidence of severe or uncontrolled systemic diseases which, in the view of the investigator, makes it undesirable for the patient to participate in the study
* Evidence of significant clinical disorder or laboratory finding which, in the opinion of the investigator makes it undesirable for the patient to participate in the study
* Any other serious uncontrolled medical conditions
* Clinical evidence of metastatic disease
* Any pregnant or lactating woman
* Any patient with a medical or psychiatric condition that impairs their ability to give informed consent
* Any patient who is currently involved in, or who has recently been involved in other research
