Abstract

fetched live from OpenAlex

BACKGROUND: The choice between palliative chemotherapy (defined as the use of cytotoxic medications delivered intravenously for the purpose of our study) and supportive care alone is one of the most difficult decisions in pediatric oncology, yet little is known about the preferences of parents and health care professionals. We compared the strength of these preferences by considering children's quality of life and survival time as key attributes. In addition, we identified factors associated with the reported preferences. METHODS: We included parents of children whose cancer had no reasonable chance of being cured and health care professionals in pediatric oncology as participants in our study. We administered separate interviews to parents and to health care professionals. Visual analogue scales were shown to respondents to illustrate the anticipated level of the child's quality of life, the expected duration of survival and the probability of cure (shown only to health care professionals). Respondents were then asked which treatment option they would favour given these baseline attributes. In addition, respondents reported what factors might affect such a decision and ranked all factors identified in order of importance. The primary measure was the desirability score for supportive care alone relative to palliative chemotherapy, as obtained using the threshold technique. RESULTS: A total of 77 parents and 128 health care professionals participated in our study. Important factors influencing the decision between therapeutic options were child quality-of-life and survival time among both parents and health care professionals. Hope was particularly important to parents. Parents significantly favoured chemotherapy (42/77, 54.5%) compared with health care professionals (20/128, 15.6%; p < 0.0001). The opinions of the physician and child significantly influenced the parents' desire for supportive care; for health care professionals, the opinions of parents and children were significant factors influencing this decision. INTERPRETATION: Compared with health care professionals, parents more strongly favour aggressive treatment in the palliative phase and rank hope as a more important factor for making decisions about treatment. Understanding the differences between parents and health care professionals in the relative desirability of supportive care alone may aid in communication and improve end-of-life care for children with cancer.

Not 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.
