Observational Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT06674811). This is a study registration, not published results. Lead sponsor: Mayo Clinic. Recruitment status: RECRUITING. Study type: OBSERVATIONAL. Enrollment: 40 participants (ESTIMATED). Conditions: Pediatric Cancer, Neuroblastoma, Sarcoma, Wilms Tumor and Other Childhood Kidney Tumors, Childhood Soft Tissue Sarcoma, Childhood Bone Sarcoma, Childhood Malignant Intestinal Neoplasm, Childhood Malignant Liver Neoplasm, Childhood Malignant Lung Neoplasm, Childhood Malignant Ovarian Neoplasm, Childhood Malignant Pleural Neoplasm, Childhood Neuroblastic Tumor, Childhood Sarcoma. Interventions: OTHER: Wearing Smartwatch; OTHER: Patient Report Outcomes; OTHER: Blood Draw; OTHER: Clinical Data Review. Primary outcome measures: Surgical resilience , 1 year. Brief summary: This observational study is to better understand how children and their families recover after the stress of major surgery for cancer so that investigators can create ways to improve resilience during recovery. The main questions it aims to answer are: 1. Can information obtained from patients and their caregivers wearing smartwatches and answering questionnaires be used to measure how patients are recovering from surgery? 2. Are there specific patterns in patients' circulating proteins and metabolites that are associated with stress after surgery? Participants, including pediatric patients undergoing surgery for cancer and their primary caregiver, will be asked to: * wear a smartwatch * complete questionnaires * allow for extra blood to be drawn for this research study when they are having their regular blood draws for clinical purposes These actions will occur at baseline prior to patients' surgery and then afterwards for up to one year. There are no changes to participants' clinical care or surgical care as a result of the study. Investigators will also collect participants' clinical information and cancer-specific outcomes. Participants will be remunerated for their time.
