Function in Cancer Patients: Disease and Clinical Determinants

Area of Science:

• Oncology
• Rehabilitation Medicine
• Patient-Reported Outcomes

Background:

• Cancer patients frequently experience functional changes during and post-treatment.
• Identifying cancer types and clinical factors influencing function is crucial for targeted rehabilitation.

Purpose of the Study:

• To evaluate patient-reported functional impairments across specific cancer types.
• To identify risk factors associated with disease status and non-cancer factors affecting function.

Main Methods:

• Cross-sectional study of 332 individuals referred to cancer rehabilitation clinics.
• Utilized the PROMIS Cancer Function Brief 3D Profile to assess physical function, fatigue, and social participation.
• Employed multivariable modeling to analyze interactions between cancer type, cancer status, and functional outcomes.

Main Results:

• An interaction between cancer type and status affected physical function and social participation.
• Active cancer status was linked to lower physical function and social participation in brain, sarcoma, prostate, and lymphoma.
• Premorbid impairments predicted lower function in non-active cancer patients; cancer type did not impact function in those with no evidence of disease.
• Fatigue was associated with younger age, higher BMI, premorbid musculoskeletal impairment, and active cancer status, independent of cancer type.

Conclusions:

• Cancer type and active disease status are key determinants of physical function and social participation.
• Premorbid conditions are significant predictors of functional decline in non-active cancer patients.
• Anticipatory guidance on common impairments can enhance cancer rehabilitation care and support patients and caregivers.
