What Researchers Did
Researchers studied 116 patients with advanced cervical cancer undergoing radiotherapy, some with hyperbaric oxygen, to see how their tumours responded.
What They Found
The study found that the amount of tumour shrinkage at the primary site accurately predicted future local tumour failure, patient survival, and whether cancer would spread. Patients who received hyperbaric oxygen alongside radiotherapy (given in 27 fractions) showed a significantly better immediate tumour response. This improved immediate response in the HBOT group also predicted better long-term outcomes.
What This Means for Canadian Patients
For Canadian patients with advanced cervical cancer, this study suggests that how much a tumour shrinks after radiotherapy, especially when combined with hyperbaric oxygen, can be a valuable sign of their long-term prognosis. A better immediate response to treatment, potentially enhanced by HBOT, could indicate improved survival and reduced risk of metastasis.

Study Limitations
This study was conducted in 1980, meaning the treatment protocols and diagnostic technologies used may not reflect current medical practices.
