Clinical Trial Summary

The aim of this study is to measure the oxygen content and interstitial fluid pressure in cervix cancer patients. Tumour oxygen content and internal pressure of tumours may be an important factor that influences the effectiveness of radiotherapy and other treatments.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	To determine if tumour oxygen tension prior to and during radiation therapy is an independent prognostic factor for primary tumour response and control in patients with cervix cancer.		tumour measurement will be done 2-3 months following completion of treatment; follow-up every 3 months for 2 years; every 4-6 months during year 3 to 5; and annually thereafter
Primary	To correlate tumour IFP measured before and during radiation therapy with oxygen tension as measured by the Eppendorf probe and to assess IFP as a prognostic factor for pelvic control.		tumour measurement will be done 2-3 months following completion of treatment; follow-up every 3 months for 2 years; every 4-6 months during year 3 to 5; and annually thereafter
Secondary	To determine if whole cell or nuclear GSH levels are correlated with tumour oxygen tension and with tumour response and control.		follow-up every 3 months for 2 years; every 4-6 months during year 3 to 5; and annually thereafter
