Evaluation of quality of life of patients with solitary renal cancer metastases in bones before and after surgical treatment in combination with targeted therapy and without it

Background. Currently, treatment tactics for oligometastatic renal cancer are a debatable topic due to relatively localized process and high risk of skeletal-related events (SRE). Therefore, the effect of treatment on quality of life of these patients is an important subject.Aim. To evaluate quality of life of patients with solitary renal cancer metastases in the bones before and after surgical treatment in combination with targeted therapy and without it.Materials and methods. The study included 64 patients with solitary bone metastases and symptoms of SRE. The patients underwent surgical treatment due to solitary bone metastases of renal cancer in combination with targeted therapy (1st group; n = 25) and without targeted therapy (2nd group; n = 39). The effects of surgical treatment on patients’ condition were evaluated using the EORTC-QLQ-C30 questionnaire.Results. In the 1st group, no statistically significant differences were shown for 8 of 30 indicators of the EORTC-QLQ-C30 questionnaire: restrictions in daily activities, dyspnea, appetite loss, nausea, vomiting, fatigue, tension, financial difficulties. The rest of the indicators showed statistically significant shift toward improvement. In the 2nd group, 7 of 30 indicators did not show statistically significant differences: restrictions in daily activities, dyspnea, sleep disorders, appetite loss, diarrhea, tension, financial difficulties. The rest of the questionnaire points also showed improvement (especially in decreased pain syndrome). In patients of the 2nd group before and after surgery, need for rest, fatigue, appetite loss and restrictions in performing work were more pronounced than in the 1st group. Additionally, after surgery patients of this group required more time in the chair and had more frequent diarrhea, while prior to surgery they complained more of nausea and fatigue. The last 2 parameters evaluating overall quality of life were higher in the 1st group before and after surgery which shows better baseline condition of these patients which was not affected by the treatment.Conclusion. Therefore, surgical treatment of renal cancer bone metastases both in combination with targeted therapy and without it significantly improves quality of life according to the results of quality of life evaluation using the EORTC-QLQ-C30 questionnaire in patients of the studied groups.
