Abstract
Objectives
Perceived cancer-related stigma can affect mental health and potentially treatment choices for patients with cancer. Nevertheless, perceived stigma is not very well understood in Asia. This study investigated across six developing Asian countries: 1) the prevalence of perceived stigma among advanced cancer patients, 2) its risk factors, and 3) its association with patient treatment preferences.
Methods
This cross-sectional study recruited patients receiving oncology care across major hospitals in Bangladesh, China, India, Philippines, Sri Lanka and Vietnam. Participants (N = 1358) were adults diagnosed with stage IV metastatic solid cancer who completed self-reported surveys. Multi-variable logistic regression and ordered logit models examined the associations with perceived stigma and variables of interest.
Results
Across the countries, 35%, 95% CI [32%, 38%] of patients reported experiencing at least one facet of cancer-related stigma often or always, while 60% [57%, 63%] reported it occurring occasionally. Top-endorsed facets of perceived stigma across the Asian countries suggest a distinct pattern. Having knowingly engaged in health-risk behaviours (OR = 2.03-2.24, 95% CI [1.14-1.19, 3.43-4.41]), unemployment (2.64 [1.67, 4.19]) and body image change (1.57 [1.00, 2.45]) were associated with higher odds of perceived stigma, while time mitigated perceived stigma (0.49-0.65 [0.30-0.45, 0.76-0.92]). Perceived stigma was associated with lower odds of preference for life-extending treatments, although the associations did not hold up in the adjusted model.
Conclusions
Perceived stigma is unique among Asian advanced cancer patients. Stigma is important to assess and address, taking into consideration the various sociodemographic, clinical and psychological factors of cancer patients.
