Burden of chronic disease comorbidities among cancer patients at Queen Elizabeth and Kamuzu Central Hospitals in Malawi: an exploratory cross-sectional study

Abstract

Introduction: chronic disease comorbidities are common among cancer patients in most parts of the world, however; there are limited data on the same for Malawi. Comorbidities worsen clinical outcomes and are associated with lower quality of life among cancer patients. We aimed at estimating chronic disease comorbidities and associated factors among cancer patients attending oncology services at the Queen Elizabeth Hospital (QECH) and Kamuzu Central Hospital (KCH) in Blantyre and Lilongwe respectively.

Methods: we conducted a cross-sectional study at QECH and KCH in Malawi from January to March 2021. Participants were recruited using simple random sampling technique at the oncology clinics and were interviewed using structured questionnaires. The College of Medicine Research and Ethics Committee (COMREC) approved the study and informed consent was obtained with each participant. Data were analyzed in Stata version 14 and summary statistics were presented as frequencies and proportions.

Results: we interviewed 398 cancer patients and the mean age was 45.4years (SD± 12.77). The common cancers were cervical (30%), Kaposi´s sarcoma (24%), breast (11%), esophageal (4%) and leukemia (4%). The prevalence of chronic disease comorbidities was 61.56% (n=398) and common conditions included: HIV and AIDS (43%), depression (9%) hypertension (8%) and anemia (9%). Chronic disease comorbidities were significantly associated with formal employment (p<0.01) and obesity (p<0.02).

Conclusion: chronic disease comorbidities were prevalent among cancer patients in the study settings in Malawi. There is a need to develop a multidisciplinary approach when managing cancer patients with emphasis on active screening for the common conditions as reported by this study.
