Quality of life (QOL) in patients with esophageal cancer treated with radiation (RT) in the radical setting.
Bibliographic record
Abstract
186 Background: QOL is poorly documented in patients with esophageal carcinoma treated with curative intent, especially trimodality therapy. QOL and survival outcomes were evaluated in a single centre prospective cohort study of esophageal carcinoma patients treated with RT in the radical setting. Methods: Patients completed the EORTC-QLQC30 at baseline, the end of RT, 6 months and 1 year after RT. A 10-point difference in scores was considered clinically significant. Results: Thirty-three of 45 consequently treated patients between February 2012 and June 2014 participated, all male, median age 63 years (range 40-76), with T1-4N1-3M0 disease (AJCC 7thedn), median follow up 0.9 years (range 0.1-2.3). Four patients were treated definitively with chemoradiation 45-50Gy in 25 fractions; 14 neoadjuvantly 45-50Gy in 25 fractions; 15 neoadjuvantly 41.4Gy in 23 fractions, with concurrent chemotherapy. Compliance for questionnaire completion was 80-100%. 2 year overall survival (OS) and disease free survival (DFS) were 77% and 63%. Median scores on role, social, fatigue and appetite showed clinically significant worsening at the end of RT; in addition statistical significance was found for global QOL, physical, nausea/vomiting, and shortness of breath [median difference (MD): global -8.3 p=0.004, physical -6.6 p=0.003, role -16.6 p=0.001, social -16.6 p=0.78, nausea/vomiting 8.3 p=0.02, fatigue 22.2 p=0.001, shortness of breath 0 p=0.037, appetite 33.3 p=0.009]. At 6 months post RT global QOL (MD -16.6 p=0.23), physical (MD -13.3 p=0.007), role (MD -16.7 p=0.11) and fatigue (MD 11.1 p=0.18) were clinically significantly depressed. At one year all scores had returned to baseline, except pain, which was clinically significantly worse (MD 16.7 p=0.41); 64% of the cohort reported worse pain compared to baseline. Although global QOL on average returned to normal, 46% reported this to be clinically worse at one year compared to baseline. No association was found between baseline global QOL and OS (p=0.15) or DFS (p=0.57). Conclusions: QOL was worsened in several domains during and up to 6 months post RT. At one year all scores had returned to baseline except for pain which was significantly worsened in 64% of patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
