Health-related Quality of Life, Symptom Severity, and Pain Among Patients Treated With Alpelisib for PIK3CA-related Overgrowth Spectrum: A Mixed-methods Observational Study

PROMIS-29 + 2 profile for adult self-report

时间窗: Up to 4 months

Patient-Reported Outcomes Measurement Information System (PROMIS)-29 +2 profile. The PROMIS-29 plus 2 Profile v2.1 is designed for adults ≥18 years of age and includes 29 items across the following domains: depression, anxiety, physical function, pain interference, fatigue, sleep disturbance, ability to participate in social roles and activities, cognitive function on a scale of 1 (worst) to 5 (best), and pain intensity (on a scale ranging from 0 (no pain) to 10 (worst pain imaginable).

PROMIS pediatric profile for adolescent self-Report and Caregiver-Proxy

时间窗: Up to 4 months

The PROMIS Pediatric-25 Profile v2.0 is designed for self-report by children ages 8-17; It is designed for completion by a parent proxy on behalf of children ages 5-17. These assess depressive symptoms, anxiety, physical function-mobility, pain interference, fatigue, peer relationships, on a scale of 1 (worst) to 5 (best) and pain intensity scale ranging from 0 (no pain) to 10 (worst pain you can think of). The content of the pediatric and parent-proxy forms are identical, except for minor modifications to account for differences in responders (e.g., "I felt worried" vs "My child felt worried").

PROMIS pediatric sleep disturbance for Adolescent Self-Report and Caregiver-Proxy

时间窗: Up to 4 months

The PROMIS sleep disturbance short form includes 4 items that assess difficulty falling asleep, sleeping through the night, problems with sleep, and trouble sleeping on a scale of 1 (worst) to 5 (best). In order to achieve similar domain coverage across the entire sample, the PROMIS Pediatric and Parent-Proxy Sleep Disturbance Short Form 4a will be administered to participants under the age of 18 and caregivers of children with PROS, since unlike the adult PROMIS Profile, the pediatric and parent-proxy PROMIS profile does not include a sleep disturbance domain.

EQ-5D-5L for Adult self-report

时间窗: Up to 4 months

The EuroQoL-5 Dimension (EQ-5D-5L) is a simple, generic measure that includes only 5 basic domains common to many generic health status measures: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The form used in this study (EQ-5D-5L) has 5 response categories for each dimension (no problems, slight problems, moderate problems, severe problems and extreme problems). The EQ-5D-5L was developed for completion by adults

EQ-5D-Youth for adolescent Self-Report and Caregiver-Proxy

时间窗: Up to 4 months

The EQ-5D-Y is based on the EQ-5D-3L but assesses the 5 dimensions using language that is more suitable to children/adolescents (the 5 dimensions are: mobility, looking after oneself, doing usual activities, having pain or discomfort, and feeling worried, sad, or unhappy). The 5 dimensions are answered using a 3-point response scale, where higher scores indicate better outcome. The EQ-5D-Y also has a proxy version that assesses the same domains as the EQ-5D-Y.

Brief Pain Inventory for Adult Self-Report and Adolescent Self-Report

时间窗: Up to 4 months

The BPI is a multi-item assessment of pain. This assessment includes 2 domains that, together, assess the overall pain experience: pain severity and pain interference. Three BPI items will be administered as part of the current study: one item assesses pain at its worst over the past 24 hours , one item assesses where on the body pain is experienced, and one item assesses the type of pain that is experienced. The worst pain item includes an 11-point response scale ranging from 0 (no pain) to 10 (pain as bad as you can imagine). A diagram of the human body (front and back) is provided for responders to mark the areas of pain and the area that hurts the most. A series of descriptors (e.g., burning, tiring, and numb) will be provided for the responders to indicate whether each adjective applies to their pain. As this endpoint has not been adapted for proxy report, it will only be completed by adolescents and adults who are able to self-report.

Global impression of symptom severity

时间窗: Up to 4 months

A single item will be fielded to all 3 groups of participants, asking for an assessment of the overall severity of symptoms experienced. This item includes 5 response options: no symptoms, mild, moderate, severe, and very severe. Minor modifications are made to the item wording to account for differences between adult/child self-report and caregiver proxy-report (e.g., changing "your overall symptoms" to "your child's overall symptoms").

Modified PROMIS dyspnea severity for adult Self-Report and Adolescent Self-Report

时间窗: Up to 4 months

Two items will be used to assess a specific symptom: shortness of breath. These items are based on 2 items in the PROMIS Dyspnea Severity item bank, but with a 24-hour recall: * Shortness of breath when walking up 10 stairs * Shortness of breath when talking while walking The 2 PROMIS dyspnea severity items will be answered using a 5-point response scale: No shortness of breath, Mildly short of breath, Moderately short of breath, Severely short of breath, I did not do this in the past 24 hours. There is no proxy version of the PROMIS Dyspnea Severity item bank, and thus the dyspnea severity items will not be administered to caregiver participants of the current study.
