Abstract
BACKGROUND: Late radiation tissue injury is a serious complication of radiotherapy for patients with gynecologic malignancies. Strategies for managing pain and other clinical features have limited efficacy; however, hyperbaric oxygen therapy (HBO(2)) may be an effective option for some patients. METHODS: In a systematic review of the literature, the Ovid medline, embase, Cochrane Library, National Guidelines Clearinghouse, and Canadian Medical Association Infobase databases were searched to June 2009 for clinical practice guidelines, systematic reviews, randomized controlled trials, or other relevant evidence. Studies that did not evaluate soft tissue necrosis, cystitis, proctitis, bone necrosis, and other complications were excluded. RESULTS: Two randomized trials, eleven nonrandomized studies, and five supporting documents comprise the evidence base. In addition, information on the harms and safety of treatment with HBO(2) were reported in three additional sources. There is modest direct evidence and emerging indirect evidence that the use of HBO(2) is broadly effective for late radiation tissue injury of the pelvis in women treated for gynecologic malignancies. CONCLUSIONS: Based on the evidence and expert consensus opinion, HBO(2) is likely effective for late radiation tissue injury of the pelvis, with demonstrated efficacy specifically for radiation damage to the anus and rectum;the main indication for HBO(2) therapy in gynecologic oncology is in the management of otherwise refractory chronic radiation injury;HBO(2) may provide symptomatic benefit in certain clinical settings (for example, cystitis, soft-tissue necrosis, and osteonecrosis); andHBO(2) may reduce the complications of gynecologic surgery in patients undergoing surgical removal of necrosis.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
