667 Background: Sunitinib and pazopanib are are effective treatment options for metastatic Renal cell carcinoma (mRCC) and both may impair patient’s quality of life (QOL). There has been no direct comparison between these agents and their effect on these domains. Methods: A prospective study of mRCC patients who had received Sunitinib or Pazopanib as a first line treatment was conducted. A set of questionnaires has been developed in-house, influenced by existing recognised tools, such as EORTC-C 30 and PHQ-9, and is tailored to focus on relevant QoL issues patients face. This questionnaire named as Patient reported outcome tool. They primarily relate to physical, emotional and social functioning in the quality of life of patients. Each category has 4 questions. The questions are quite generic and allow patients to apply them to what’s important in their lives. Answers are on a scale of 0-10. The purpose of the questionnaire is to assess a balance of physical, cognitive and independence related aspects of their life over the course of their treatment. All patients are asked to complete the baseline questionnaire and then in every clinical visit. Results: Data were collected prospectively of metastatic RCC patients who had received Sunitinib or Pazopanib from May 2017 to Aug 2018. Total 45 patients were included, 23 received Pazopanib and 22 were on Sunitinib. There was a higher rate of significant worsening for the physical well-being subscale for Sunitinib versus Pazopanib. Patients on Sunitinib reported worsening tiredness, skin problems and sleep disturbance. Socially, patients on Sunitinib reported more closer to family, better interaction with friends and more motivated to go out. Problem with feeling sad, fear of death and anxiousness were more pronounced on Pazopanib arm. Conclusions: Our study suggested that there are marked differences between Sunitinib vs Pazopanib and their effects on patients physical, emotional and social wellbeing. Physical function was more influenced by sunitnib while pazopanib has more effect emotional wellbeing. Further studies are warranted to confirm these findings.
