Abstract

fetched live from OpenAlex

In Brief Background: Gastrectomy remains a major operation with potential for significant deterioration in patients' health-related quality of life (QOL). This study assessed differences in QOL among patients after distal (DG), proximal (PG), or total (TG) gastrectomy. Methods: We prospectively enrolled patients undergoing gastrectomy at our institution between 2002 and 2007. Participants completed the European Organization for Research and Treatment of Cancer cancer (QLQ-C30) and gastric (QLQ-STO22) questionnaires preoperatively and at 5 postoperative intervals up to 18 months. We compared changes from baseline in patients based on extent of resection (proximal, distal, or total) using generalized linear models, adjusting for age, stage of disease, and (neo)adjuvant therapy. We converted QOL raw scores to reflect the proportion of patients with clinically significant deterioration based on the minimal important difference. Results: We included 134 patients: 82 DG, 16 PG, and 36 TG. In the immediate postoperative period, 55% of patients suffered significant impairment in their global QOL. This improved in most patients by 6 months, although 20% to 35% continued to have substantially worse QOL than before surgery. Patients who underwent PG suffered from significantly more clinical reflux [70% vs 35% (DG), 40% (TG)], nausea/vomiting (60% vs 25%, 30%), and global QOL impairment (60% vs 30%, 30%) than patients who underwent DG or TG, whose QOL scores were similar. These differences persisted up to 18 months postoperatively. Conclusions: Surgeons should discuss expectations of QOL impairment with their patients before gastrectomy and reassure them that most symptoms resolve by 6 months after operation. Patients who undergo PG suffer from worse QOL impairment than patients who undergo DG or TG. In this prospective cohort study including 134 patients undergoing gastrectomy for cancer, 55% suffered significant impairment in their global quality of life. Patients who underwent proximal gastrectomy suffered from significantly more clinical reflux, nausea/vomiting, and global quality of life impairment than patients who underwent distal or total gastrectomy. These differences persisted up to 18 months postoperatively.

Full frame distilled prediction

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.
