Functional Effects of Pneumonectomy and Bilobectomy for Lung Cancer
Bibliographic record
Abstract
28 patients with lung cancer had pulmonary function studies before and 3 months to 3 years after pneumonectomy or bilobectomy. Preoperative profiles showed a slight obstructive pattern with air trapping and perturbated gas exchange. The obstructive pattern was not related to endoscopy findings, but the alveoloarterial gradient oxygen gradient was smaller in those with complete lobar occlusion. After surgery, the volume loss was related to the amount resected, being greater after right pneumonectomy than after left pneumonectomy and least after bilobectomy. The obstructive pattern remained unchanged. Diffusion of carbon monoxide decreased significantly less than volumes after pneumonectomy but proportionally after bilobectomy. Those with increased alveoloarterial oxygen gradient or increased physiologic dead space experienced a significant improvement of their gas exchange after surgery.

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.
