Introduction: Cancer and its treatment have a broad impact on patients' Quality of Life (QoL). Previous researches showed that many factors in Comprehensive Geriatric Assessment (CGA) affect QoL. CGA could predict toxicity, overall survival rate and can help adjust the choice and intensity of treatment in each patient. However, there has been no research explicitly exploring factors related to the QoL in older patients with Non-Hodgkin's Lymphoma (NHL). This research aims to explore the how factors in CGA relate to the QoL in older patients with NHL. Materials and Method: The study design was cross-sectional in NHL patients aged ≥ 60 years, research was conducted in Integrated Geriatric Polyclinic and Hemato-Oncology Polyclinic of three public hospitals in Jakarta, during March–August 2019. Results: There were 62 subjects, with a median age of 66 years, 56.5% male. The result showed that most of the patients have a good QoL, based on each domain of SF-36 and EORTC QLQ-C30. In multivariate analysis, it was found that depression and frailty status were related to PCS SF-36 domain with PR 12.086 (95% CI 1.596–92.124) and PR 5.622 (95% CI 1.060–29.807), respectively. Multivariate analysis with SF-36's Mental Component Summary (MCS) showed a significant relationship with depression status with PR 24.400 (95% CI 2.961–140.539). While the results of multivariate analysis with the EORTC QLQ-C30 functional scale showed a significant relationship with the ECOG performance score with PR 171 (95% CI 8.470–3452.28). Discussions: After multivariate analysis, only frailty status, depression status and ECOG performance score have a statistically significant relationship.
