Аннотация:Abstract Background Since renal cell carcinoma(RCC) is insensitive to conventional chemoradiotherapy, molecularly targeted drugs are commonly used treatments for unresectable advanced RCC. The aim of this study was to explore the efficacy and safety of TACE + sunitinib vs. sunitinib in the treatment of unresectable advanced RCC. Methods This study included 98 patients with unresectable advanced RCC who were treated in Union Hospital from January 2015 to December 2018, and they met the criteria. They were divided into two groups: TACE + Sunitinib group (N = 47) and Sunitinib group (N = 51). We conducted a retrospective study to analyze the efficacy and safety of the two groups of patients. Results (1)TACE + Sunitinib group: 4 patients (8.5%) achieved CR, 27 patients (57.5%) achieved PR, 9 patients (19.1%) achieved SD, and 7 patients (14.9%) achieved PD. Sunitinib group, 0 patients (0%) achieved CR, 20 patients (39.2%) achieved PR, 14 patients (27.5%) achieved SD, and 17 patients (33.3%) achieved PD. (P = 0.017) (2)ORR: TACE + sunitinib group, 66.0%; sunitinib group, 39.2%. (P = 0.009) (3)DCR: TACE + sunitinib group, 85.1%; sunitinib group, 66.7%. (P = 0.038) (4) In the TACE + sunitinib group, mPFS was 15.6 months, mOS was 35.0 months; in the sunitinib group, the mPFS was 10.9 months, mOS was 25.7 months. (P < 0.001) (5) The incidence of abdominal pain, fever, and vomiting was higher in the TACE + sunitinib group than in the sunitinib group (abdominal pain: 55.3% vs. 13.7%; fever: 61.7% vs. 7.8%; vomiting: 40.4% vs. 19.6%; P < 0.05). The technical success rate of TACE in TACE + Sunitinib group is 100%. Conclusions The TACE + sunitinib group had higher ORR and DCR, longer OS and PFS than the sunitinib alone group. TACE combined with sunitinib can play a complementary role and is a safe and effective treatment for advanced RCC.
