Clinical outcome of salvage surgery in patients with recurrent oral cavity cancer: A systematic review and meta‐analysis
Bibliographic record
Abstract
This systematic review and meta-analysis investigated the impact of salvage surgery on 5-year overall survival (OS) and prognostic factors in recurrent oral cavity cancer (rOCC) patients. Relevant literature before May 2022 was reviewed, including retrospective cohort studies and observational studies comparing salvage surgery to other treatments. Risk-of-bias assessments were conducted using the Newcastle-Ottawa scale. Statistical and subgroup analyses assessed the impact of salvage surgery on 5-year OS and prognostic factors. 3036 documents were initially retrieved, with 14 retrospective cohort studies (2069 participants) included. Meta-analysis of 5-year OS in salvage surgery patients yielded a rate of 43.0%. Subgroup analysis showed higher OS in Asians (49.9% vs. 36.9%, p = 0.003) and late-relapse (63.8% vs. 30.0%, p = 0.004) groups. Prognostic factors revealed hazards associated with nodal recurrence, extranodal extension, and perineural invasion. Salvage surgery is a viable option for rOCC patients, showing favorable 5-year OS outcomes. Low publication bias enhances study reliability, but its single-arm design limits conclusions on salvage surgery superiority over other treatments.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
