Burden of Fatigue and Dyspnea and Their Association with Health-Related Quality of Life Among Cancer Patients: An Analytical Cross-Sectional Study

Abstract

Background: Fatigue, dyspnea, and impaired quality of life (QoL) are among the most commonly reported symptoms in cancer patients. These symptoms can significantly impact functional independence, emotional well-being, and treatment outcomes. Identifying the prevalence of these symptoms can guide more effective supportive care and rehabilitation strategies.  Aim: To determine the prevalence of fatigue and dyspnea and its association with health releated quality of life among various types of cancer patients.  Materials and Methods: An Analytical cross-sectional study was conducted involving 205 cancer patients, including individuals diagnosed with lung, breast, oral cavity, liver, prostate, thyroid, and other cancers. Participants were assessed using standardized tools: fatigue was evaluated using the Brief Fatigue Inventory Scale, dyspnea was measured with the Modified Medical Research Council (mMRC) Dyspnea Scale, and quality of life was assessed using the EORTC QLQ-C30 questionnaire. Data were analyzed to determine the overall cancer-type-specific prevalence of fatigue, dyspnea and impaired quality of life.
