What Researchers Did
Researchers conducted a randomised clinical trial with 233 patients with advanced uterine cervical cancer to compare conventional radiotherapy in air versus hyperbaric oxygen as a radiotherapeutic adjuvant.
What They Found
Among 233 patients, there was no statistically significant difference in absolute no evidence of disease (NED) survival rates between the hyperbaric oxygen and air groups, either overall or by stage. Furthermore, the incidence of failures in the irradiated area showed no difference between the two treatment arms.
What This Means for Canadian Patients
This 1977 study suggests that hyperbaric oxygen as an adjuvant to radiotherapy may not improve survival or local control for Canadian patients with advanced cervical cancer. Modern treatment protocols for cervical cancer have evolved significantly since this study, offering more effective and targeted therapies.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
This study presents preliminary results from 1977, and the abstract is incomplete, limiting a full understanding of its findings and potential long-term outcomes.
