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.
