Purpose: To determine quality of life (QoL) of cancer patients in The Republic of Trinidad and Tobago using the European Organization for Research and Treatment of Cancer Care Quality of Life Instrument (EORTC QLQ-C30) and examine relationships between QoL and socioeconomic and medical variables.
Method: A cross-sectional study, consisting of 480 cancer patients being managed at the National Radiotherapy Centre, was conducted. One-way, multiple analysis of variance (MANOVA) with post hoc testing was used to analyze relationships between socioeconomic and medical variables and scales on the EORTC QLQ-C30. Stepwise linear regression was used to evaluate which independent variables contributed to the global QoL and function scores.
Results: Participants were of mean age 64.1 ± 12.1 years (males) and 56.7 ± 16.6 years (females). Mean values for global QoL and function scales were below 75. Persons in younger age groups had significantly better physical and cognitive function scores (p < 0.05). Males had higher emotional function scores than females (p < 0.05). Persons with higher income and education had better scores on all function scales, except social, and less symptoms (p < 0.05). Persons receiving chemotherapy had more nausea/vomiting, appetite loss, and constipation (p < 0.05).
Conclusion: Age, income, education, and cancer treatment were factors most associated with scores on the EORTC QLQ-C30. Further research is required in this population to examine these variables in more depth and explore methods to improve QoL of cancer patients in this population.
