Abstract Patients who have received treatment for lymphoma or chronic lymphocytic leukemia (CLL) experience numerous side effects which can have a profound impact on health-related quality of life (HRQoL). Some of the most underreported are adverse psycho-social outcomes (APSO). We explored the prevalence and severity of APSO’s amongst a globally derived sample from this patient population. Patient reported outcomes (PRO’s) were collected from an anonymous global survey directed at patients with lymphoma and CLL. Nineteen different APSO’s were pre-specified in the survey. Prevalence was captured with severity assessed using a 5-part Likert scale. Latent class analysis (LCA) was used to cluster patients with a propensity for experiencing multiple APSO’s. Resultant clusters were investigated to determine if they were enriched for selected demographics. Responses were received from 5984 patients who had received treatment for lymphoma or CLL where the median age was 64, ranging from 18 - 94 years. Sixty percent were female. Fear of progression/relapse was the most prevalent APSO (49%; Table 1). Most APSO’s had severity scores above 3 indicating a moderate level of severity (Table 1). LCA identified a cluster comprising 12% of the patients who experienced all APSO’s at a higher rate than the remaining patients. Both younger age and female sex were significantly enriched in this cluster (p&amp;lt;0.0001). The results suggest that a segment of patients experience multiple APSO’s which can compound to create a significant overall degradation in HRQoL. While younger age and female sex are enriched in this segment, further exploration is needed to identify those with heightened risk for multiple APSO’s. The application of mitigation strategies in those suffering from APSO’s may help to improve patient’s HRQoL during treatment, recovery and rehabilitation.
