Occult malignancy rate associated with thoracodorsal vessel dissection for free flap breast reconstruction
Bibliographic record
Abstract
BACKGROUND: The rate of breast reconstruction following mastectomy is increasing, and currently sits at about 15%. Free flap reconstruction techniques using the thoracodorsal vessels as recipients provide an opportunity for a "second look" at the axillary nodal basin post-mastectomy. The purpose of this study was to determine the occult malignancy rate associated with free flap breast reconstruction. METHODS: A retrospective chart review was performed to ascertain the occult malignancy rate of women who received a delayed free flap reconstruction at our institution between 1990 and 2001. Any additional therapy as a result of a positive result was also recorded. RESULTS: Free flap breast reconstructions between 1990 and 2001 totalled 322, and of those 136 reconstructions were delayed and met our inclusion criteria. An occult malignancy rate of 3.6% (five patients) was identified for these patients. Four patients received additional therapy as a result of this finding. CONCLUSION: This study serves to alert reconstructive surgeons to the potential for finding occult tumour during free flap breast reconstruction.

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.
