Advanced cancer patients’ changes in terminal illness understanding (TIU) and their psychological well-being.
Bibliographic record
Abstract
11617 Background: Although accurate TIU is necessary for informed treatment decision-making, clinicians worry that patients’ recognition of the terminal nature of their illness may lower psychological well-being. This study examines if such recognition is associated with lowered psychological well-being, that persists over time. Methods: Data came from 87 advanced cancer patients, with a life expectancy of less than 6 months. Patients were assessed pre and post an oncology visit to discuss cancer restaging scan results, and again one month later (follow-up). TIU was assessed at pre and post as the sum of four indicator variables — understanding of terminal nature of illness, curability, stage, and life-expectancy — and a TIU change score was computed (post minus pre). Psychological well-being (psychological symptoms subscale, McGill questionnaire) was assessed at pre, post, and follow-up, and two change scores were computed (post minus pre; follow-up minus post). Results: Changes toward more accurate TIU was associated with a corresponding decline in psychological well-being ( r = -0.33, p < .01), but thereafter was associated with subsequent improvements in psychological well-being ( r = .40, p < .001). This pattern persisted even after adjustment for relevant demographic factors, prognostic discussion, scan results, and physical well-being change. TIU change scores ranged from positive to negative, with some participants showing improvements in TIU ( n = 19), some showing decrements in TIU ( n = 14), and others showing stable TIU ( n = 54). Among patients with improved TIU, psychological well-being initially decreased, but subsequently recovered [7.03 (2.23) to 6.30 (1.80), to 7.63 (2.08)]; the stable TIU group showed relatively unchanged well-being [7.34 (2.37) to 7.45 (2.32), to 7.36 (2.66)], and the less accurate TIU group showed an initial improvement followed by a subsequent decline [6.30 (2.62) to 7.36 (2.04), to 5.63 (3.40)]. Conclusions: Improved TIU may be associated with initial decrements in psychological well-being, followed by patients rebounding to baseline levels. Concerns about psychological harm may not need to be a deterrent to having prognostic discussions with 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.
