About this study
Official title: Digital Biomarker and Omics-Based Assessment of Surgical Resiliency in Children Undergoing Solid Tumor Resection: A Pilot Feasibility Study
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:
- Can information obtained from patients and their caregivers wearing smartwatches and answering questionnaires be used to measure how patients are recovering from surgery?
- 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Wearing SmartwatchOther
Patients and their caregivers will be asked to start wearing a smartwatch prior to surgery and continuing to wear it for one year following surgery at all times except when bathing or swimming, eating, undergoing a procedure, or if refusing to wear them. The smartwatches collect motor activity by minutes spent being sedentary, active, or highly active, heart rate, and sleep duration and stages. Data from the smartwatches syncs with Garmin connect using Fitabase to allow the study team to review the data.
Patient Report OutcomesOther
To obtain patient-reported outcomes (PROs), questionnaires will be administered at time of enrollment, in the two weeks prior to surgery if applicable, and at 1, 2, 4, 8, 12, 16, 20, 24, 34, 44, and 54 weeks postoperatively. Questionnaires can be completed electronically, over the telephone or in person. The PedsQL Cancer Module and Patient Health Questionnaire depression scale (PHQ-9) will be utilized for questionnaires.
Blood DrawOther
When patients are having blood drawn as part of their regular care, extra blood may be drawn for this study. Participants may opt out of this. Blood draws will occur preoperatively and at intervals postoperatively for proteomic, metabolomic, and exposomic testing.
Clinical Data ReviewOther
Clinical data will be collected and stored in a database by study staff. This includes patient demographics, diagnosis characteristics including staging and risk group, treatment characteristics, and outcomes including length of stay following surgical intervention, readmissions, surgical complications including surgical site infection, time off therapy/time to resumption of chemotherapy.

|---|---|---|
| Patient | Children and young adults 3-18 years old who are undergoing surgical resection of an extracranial solid tumor. Receives: Other: Wearing Smartwatch; Other: Patient Report Outcomes; Other: Blood Draw; Other: Clinical Data Review | |

What is being measured
The primary outcome is the main question the study is designed to answer.
Surgical resilience
Using smartwatches, we will assess motor activity by minutes spent being sedentary, active, or highly active, heart rate, and sleep duration and stages. This information will be collected before and after surgical resection. Data from the smartwatches syncs with Garmin connect using Fitabase which allows the study team to monitor and analyze the data. Results will be correlated with questionnaires responses, to see if there are digital biomarker patterns associated with return to baseline quality of life postoperatively.
Measured: 1 year
Secondary outcomes (3)
Quality of life - PedsQL
Results from Pediatric Quality of Life Inventory (PedsQL) Brain Tumor Module will be used to evaluate the quality of life outcomes in patients up to 18 years old. PedsQL™ assessments include 23 items answered on a Likert scale where 0=never a problem; 1=almost never a problem; 2=sometimes a problem; 3=often a problem; 4=almost always a problem.
Measured: 1 year
Quality of life - PHQ-9
The Patient Health Questionnaire (PHQ)-9 consists of 9 items related to problems over the last 2 weeks. Items are answered on a 4-point Likert scale where 0=not at all; 1=several days, 2=more than half the days; and 3=nearly every day. If any problem items were indicated, participants are asked to answer a final question with one of the following: not difficult at all; somewhat difficult; very difficult; or extremely difficult.
Measured: 1 year
Biomarkers
Participants who are the patients having surgery will have extra blood collected during routine clinical blood draws over time. This will be used for proteomic, metabolomic, and exposomic testing to see if specific proteins, metabolites, or chemicals are changed from baseline after surgery and if any levels are associated with improved resilience or quality of life.
Measured: 1 year

Primary outcome
Surgical resilience
Time frame: 1 year
Using smartwatches, we will assess motor activity by minutes spent being sedentary, active, or highly active, heart rate, and sleep duration and stages. This information will be collected before and after surgical resection. Data from the smartwatches syncs with Garmin connect using Fitabase which allows the study team to monitor and analyze the data. Results will be correlated with questionnaires responses, to see if there are digital biomarker patterns associated with return to baseline quality of life postoperatively.
