Abstract

fetched live from OpenAlex

We evaluated the effects of mediastinal lymph-node dissection on outcomes in octogenarians with primary lung cancer. Outcomes and postoperative complications were retrospectively investigated in 48 octogenarians with anatomically resected lung cancer, of whom 23 underwent a mediastinal lymph-node dissection (ND2 group) and 25 a limited lymphadenectomy (ND0-1 group). Forty-three patients underwent a lobectomy, two a pneumonectomy, and three a segmentectomy. The five-year survival rate for all was 35%, while that for those in pathological stage I was 43.3% and for those in stage II+III was 21.2%. As for lymph node dissection, the five-year survival rate for the ND0-1 group (54.3%) was superior to that for the ND2 group (21.7%) (P=0.022). For patients in pathological stage I, those rated ND0-1 had a better five-year survival than those rated ND2 (61.9% vs. 28.6%) (P=0.041). In addition, mediastinal lymph-node dissection increased the incidence of postoperative cardiac complications (P=0.004). Our results indicate that major pulmonary resection with mediastinal lymph-node dissection is associated with a higher rate of mortality in octogenarians with lung cancer.

Teacher imitation

Not 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.
