Predictive Assays In Cervix Cancer

March 3, 2026 updated by: University Health Network, Toronto

Predictive Assays in Cervix Cancer: Assessment of Hypoxia, Interstitial Fluid Pressure, and Tissue and Plasma Biomarkers of Hypoxia (CXTF10)

The experiments outlined in this proposal will compare a number of currently available techniques for assessing hypoxia and interstitial fluid pressures in patients with cervix cancer. The aim of these experiments is to establish the relationship of the clinically relevant outcome measures of tumour control and survival following radiation therapy with these biological characteristics of carcinoma of the cervix relevant to tumour hypoxia. These characteristics will be assessed in patients undergoing treatment using techniques which have reached an appropriate level of development for clinical evaluation and aim to determine the best technique for determining these parameters of the tumour microenvironment. A number of novel strategies directed at the microenvironment are undergoing or soon will be undergoing clinical evaluation and selection of appropriate patients for these trials is of great importance.

How is the study designed?

Design Details

  • Primary Purpose: Basic Science
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Assays on cervical cancer tissue
Other: Tumour Biopsies and Blood Sampling
Patients who consent to the tissue part of this study will have Biopsies taken for study purposes at the same time as their routine tumour biopsies . In addition,those who consent to the blood sampling part of the study will have their samples taken assess serum biomarkers of tumour oxygenation.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
To understand the mechanisms by which hypoxia and IFP influence disease progression, and response to radiotherapy, chemotherapy and other novel biologically-targeted therapies in patients with cervix cancer.
Time Frame: 3 months during the first two years, every 4-6 months during years 3 to 5 and yearly thereafter.
3 months during the first two years, every 4-6 months during years 3 to 5 and yearly thereafter.

Secondary Outcome Measures

Outcome Measure
Time Frame
To determine if tissue biomarkers of hypoxia are independent prognostic factors for relapse and survival in patients with cervix cancer.
Time Frame: 3 months during the first two years, every 4-6 months during years 3 to 5 and yearly thereafter.
3 months during the first two years, every 4-6 months during years 3 to 5 and yearly thereafter.
To determine if plasma biomarkers of hypoxia are independent prognostic factors for relapse and survival in patients with cervix cancer.
Time Frame: 3 months during the first two years, every 4-6 months during years 3 to 5 and yearly thereafter.
