Stereotactic radiation therapy for breast cancer in the elderly
Bibliographic record
Abstract
Abstract: The management of breast cancer in elderly women is going to be a major public health issue in a near future. The use of hypofractionated stereotactic radiotherapy is expanding but might be a priori not offered to older patients. We addressed the role of stereotactic radiotherapy (SBRT, 1–10 fractions) in elderly patients with breast cancer, in definitive, adjuvant and metastatic settings. Review of the literature. Of six series using SBRT for partial breast or breast boost irradiation and over 20 oligometastatic (brain, lung, liver, bone) SBRT series including patients aged ≥60 years old, no difference was found in term of efficacy (>80%) and toxicity (<5% G3-4) compared to the younger. Hypofractionation is also well adapted to the elderly, due to limited transportation-related fatigue. SBRT studies by age group are lacking. However, hypofractionated SBRT is particularly adapted to older patients with breast cancer, in term of efficacy and tolerability and should be encouraged rather than more morbid treatments whenever possible.

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.
