Hyperpolarized 13C MR Imaging of Lactate in Patients With Locally Advanced Cervical Cancer (LACC) Cervical Cancer

September 20, 2022 updated by: Sunnybrook Health Sciences Centre

Hyperpolarized 13C MR Imaging of Lactate in Patients With Locally Advanced Cervical Cancer for Treatment With Definitive Chemoradiation Therapy

The purpose of this study is to image tumour lactate in study participants with locally advanced cervical cancer. Our hypothesis is that lactate content in cervical tumours, as measured by hyperpolarized 13C Magnetic Resonance (MR) imaging, will correlate with diffusion-weighted MRI and 18FDG-PET (fluorodeoxyglucose-positron emission tomography). Furthermore, lactate imaging will potentially provide additional and more specific information regarding the metabolic activity of cervical tumours, thereby identifying regions of radiation resistance and guiding radiation treatment and brachytherapy.

Detailed Description

Patients with locally advanced cervical cancer can be offered definitive treatment with radiation therapy with concurrent chemotherapy for curative treatment. Brachytherapy is an essential part of this treatment, used to deliver high central doses after external beam radiation. Three-dimensional image-guided brachytherapy (3DIGBT) is gradually becoming the standard of care in many centres across the world. The use of Magnetic Resonance Imaging (MRI) or Computerized Tomography (CT) for planning helps ensure adequate coverage of tumours, minimizing doses to organs at risk. However, standard imaging modalities used in 3DIGBT typically include T2 and T1 weighted MRI sequences or CT scans and visualizing of the disease can often be challenging. Furthermore, it can be difficult to differentiate between active cervical cancer and fibrosis, leading to treatment of larger volumes when there is uncertainty (Akila contouring study).

High tumour lactate concentration has been linked to poor clinical outcomes in patients with solid tumours, including cervical cancers treated with radiation therapy [1, 2]. Three-dimensional imaging of tumour lactate in patients with locally advanced cervical cancers may be useful in identifying regions of radiation resistance and guiding treatment with chemoradiation and brachytherapy. The objective of this study is to image patients with locally advanced cervical cancer using hyperpolarized 13C MR imaging to obtain a measure of lactate levels in cervical tumours. Lactate images and measurements will be correlated with diffusion-weighted MRI, 18FDG-PET imaging and bioluminescence microscopy (BLI).

Up to ten participants with cervical cancer that are to receive radical treatment with radiation and possible concurrent cisplatin will be recruited for this study from Sunnybrook Health Sciences Centre (Sunnybrook). A snap-frozen biopsy of the tumour will be taken at the first clinic visit. Prior to treatment, baseline diffusion weighted MRI images and 18FDG-PET scans will be obtained. Hyperpolarized 13C MR imaging will be performed through the injection of 13C pyruvate and measurements of tumour lactate levels. Lactate levels will be correlated with measurements from bioluminescence microscopy. The images from hyperpolarized 13C MR imaging will also be compared to diffusion-weighted MR and 18FDG-PET images.

The purpose of this study is to image tumour lactate in study participants with locally advanced cervical cancer. Our hypothesis is that lactate content in cervical tumours, as measured by hyperpolarized 13C Magnetic Resonance (MR) imaging, will correlate with diffusion-weighted MRI and 18FDG-PET. Furthermore, lactate imaging will potentially provide additional and more specific information regarding the metabolic activity of cervical tumours, thereby identifying regions of radiation resistance and guiding radiation treatment and brachytherapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Active Comparator: Hyperpolarized Pyruvate (13C) Injection
Participants will be injected with the study drug Hyperpolarized Pyruvate (13C) Injection at a dose of 0.43 ml/kg and will have their cervix imaged using MRI.
Drug: Hyperpolarized 13C-Pyruvate
The new imaging method being tested is called Metabolic MRI, which provides pictures of the metabolism occurring within cancer cells. It also involves injection of a contrast agent, Hyperpolarized Pyruvate (13C) Injection, into the arm vein. The participants will be injected with the study drug at a dose of 0.43 ml/kg and then receive a MRI scan.
Active Comparator: 18F-FDG
Participants will be injected with the study drug 18F-FDG at a dose of 5 MBq/kg to a a maximum of 500 MBq (megabecquerel) and will have their cervix imaged using PET-CT imaging.
Drug: 18F-FDG
18F-FDG is a radiopharmaceutical used in medical imaging. The uptake of 18F-FDG by tissues is a marker for the tissue uptake of glucose, which is correlated with certain types of tissue metabolism, particularly in cancer cells. The participant will be injected with the study drug at a dose of 5 MBq/kg to a maximum of 500 MBq and then receive a PET scan.
