Financial Toxicity, Symptom Burden, Illness Perceptions, and Communication Confidence in Cancer Clinical Trial Participants
Bibliographic record
Abstract
PURPOSE: Cancer clinical trial (CCT) participants are at risk for experiencing adverse associations from financial toxicity, but these remain understudied. METHODS: From July 2015 to July 2017, we prospectively enrolled CCT participants referred for financial assistance and a group of patients matched by age, sex, cancer type, trial, and trial phase. We assessed financial burden of cancer care, cost concerns about CCTs, physical (Edmonton Symptom Assessment Scale [ESAS]) and psychologic (Patient Health Questionnaire-4 [PHQ-4]) symptoms, illness perceptions (Brief Illness Perception Questionnaire), and communication confidence (Perceived Efficacy in Patient-Physician Interactions). Adjusting for age, sex, race, performance status, marital status, income, insurance, and disease status, we examined associations of financial burden and cost concerns with patients' symptoms, illness perceptions, and communication confidence. RESULTS: Of 198 patients, 112 (56.6%) reported financial burden and 82 (41.4%) reported cost concerns. Higher ESAS-total (odds ratio [OR] = 1.03; 95% CI, 1.01 to 1.06; P = .001), PHQ-4 depression (OR = 1.58; 95% CI, 1.20 to 2.08; P < .001), PHQ-4 anxiety (OR = 1.26; 95% CI, 1.02 to 1.55; P = .025), and more negative illness perceptions (OR = 1.04; 95% CI, 1.00 to 1.07; P = .029) were associated with financial burden, but not communication confidence (OR = 0.98; 95% CI, 0.02 to 1.05; P = .587). Higher ESAS-total (OR = 1.03; 95% CI, 1.01 to 1.05; P = .004), PHQ-4 depression (OR = 1.36; 95% CI, 1.08 to 1.71; P = .03), PHQ-4 anxiety (OR = 1.26; 95% CI, 1.03 to 1.53; P = .018), more negative illness perceptions (OR = 1.06; 95% CI, 1.02 to 1.10; P = .001), and decreased communication confidence (OR = 0.93; 95% CI, 0.86 to 1.00; P = .029) were associated with cost concerns. CONCLUSION: In this study of CCT participants, greater symptom burden, more negative illness perceptions, and lower communication confidence were associated with financial toxicity, underscoring the importance of addressing these issues when seeking to alleviate adverse associations of financial toxicity.

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.
