Background: Healthcare providers often struggle to balance the sometimes competing considerations of maximizing quality of life (QoL) and quantity of life with disease-modifying treatment (DMT). These decisions require in-depth dialog between all parties in order to understand the concerns and perspectives of the patient and caregiver in this period. Objectives: The objectives of this study were to explore Singaporean patients' and caregivers' attitudes towards QoL and DMT, and to examine the reasons behind their beliefs. Methods: Participants were given a video vignette of a family discussing how best to care for their mother who is recently diagnosed with cancer and were interviewed regarding their thoughts on QoL and DMT for a 70-year-old patient with stage IV metastatic cancer. Subjects/Setting: A total of 21 patients and caregivers were recruited from a tertiary oncology centre. Results: Both patients and caregivers show little support for pursuing QoL, despite the likely compromise to the patients' QoL. These participants believed that not pursuing DMT was tantamount to giving up and accepting death. Whilst patients did accept that in some circumstances a QoL approach would be acceptable, caregivers remained adamant upon a DMT approach. The perspectives of caregivers reflected the influence of the Confucian-inspired practice of filial piety. Conclusion: Local sociocultural beliefs and values continue to play a significant consideration in end-of-life decision-making. However, compliance with these beliefs have evolved, with greater consideration given to clinical and QoL factors.
