Soft Tissue Radiation Injury; Patient Reported Evaluation in a Single Centre Cohort Study (STRIPE) (karolinskaUH)
Radiotherapy cures many cancers but can cause late radiation-induced tissue injury (LRTI), leading to long-term symptoms from the bladder and bowel and reduced health-related quality of life (HRQoL). Hyperbaric oxygen therapy (HBOT) is an established treatment that reduces chronic inflammation and promotes tissue repair. Randomized studies have demonstrated improvements in symptoms and quality of life, but only a small proportion of affected patients receive HBOT.
This study aims to longitudinally describe a cohort of patients with LRTI treated with HBOT at Karolinska University Hospital and to analyze associations between treatment, timing, and patient characteristics. The goal is to improve understanding of which patients benefit most from HBOT and when treatment should be initiated.

Studiebefolkning
Cohort 1 - Retrospective cohort Cohort 1 includes all patients (n = 120) with late radiation-induced tissue injury treated with HBOT and registered in the unit's clinical quality registry during the defined study period.
Cohort 2 - Prospective cohort To generate robust real-world evidence and enable identification of predictive factors with adequate statistical precision, data collection is planned for approximately 1,000 patients treated with HBOT at Karolinska University Hospital.

EPIC socre
Tidsramme: Baseline to 24 months
|
Longitudinal change in symptoms after HBOT measured by Extended Prostate Index Composite 26 items (EPIC-26) score for bladder and bowel.
Score desrcibe a composite of symtoms related to LRTI from 0-100, where 0 is worse symtoms and 100 is no symtoms.

Longitudinal change in HRQoL (EQ-5D) evaluated by EuorQoL 5 Dimensions (EQ-5D) after HBOT.
EQ-5D index range from 0-1 with country specific vale sets., in Sweden the range is -0.3-1).
EQ-5D also has a visual analoge scale (EQ-VAS) from 0-100, where 0 is low and 100 is high HRQoL.

Tidsramme: Baseline to 24 months

Longitudinal change in HRQoL evaluated by RAND 36-Item Health Survey (RAND-36) after HBOT.
RAND-36 evaluates overall well-being across eight physical, emotional, and social domains.
Raw answers are converted to a scale from 0 to 100, where higher scores indicate a more favorable or better health state.
