Abstract:
Objective:To investigate the risk factors of massive intraoperative bleeding in patients with renal cell carcinoma and tumor thrombus.Methods:Data of 177 patients with renal cell carcinoma and tumor thrombus in Peking University Third Hospital from January 2017 to July 2020 were retrospectively analyzed, including 129 males and 48 females. The average age was (59.3±10.6) years. The tumors were located on the left in 66 cases and on the right in 111 cases. The tumor size was less than 7 cm in 52 cases, 7-10 cm in 63 cases and >10 cm in 62 cases. There were 45 cases with tumor thrombus of Mayo grade 0, 101 cases of grade Ⅰ-Ⅱ and 31 cases of grade Ⅲ-Ⅳ. There were 93 cases undergoing laparoscopic surgery and 84 cases undergoing open surgery. Segmental resection of vena cava was performed in 30 cases. Massive intraoperative bleeding was defined as the total of bleeding ≥ 1 500 ml. The difference of clinical data between massive bleeding group and non-massive bleeding group was compared. Logistic multivariate regression was used to analyze the independent risk factors of massive intraoperative bleeding.Result:The median intraoperative bleeding of 177 cases was 600 (200, 1 500) ml. There were 50 cases (28.2%) in massive bleeding group and 127 cases(71.8%) in non-massive bleeding group. Comparing massive bleeding group and non-massive bleeding group, the preoperative ASA scores of 1-2 scores were 38 cases (76.0%) and 114 cases (89.8%) respectively, and the 3 scores were 12 cases (24.0%) and 13 cases (10.2%) respectively ( P=0.029); Hemoglobin was (116.8±23.1) g/L and (127.6±23.6) g/L respectively ( P=0.006); The tumor size less than 7 cm in 10 cases (20.0%) and 42 cases (33.1%), 7-10 cm in 15 cases (30.0%) and 48 cases (37.8%), and >10 cm in 25 cases (50.0%) and 37 cases (29.1%)( P=0.024); Tumor thrombus of Mayo grade 0 were 3 cases (6.0%) and 42 cases (33.1%), grade Ⅰ-Ⅱ were 27 cases (54.0%) and 74 cases (58.3%), grade Ⅲ-Ⅳ were 20 cases (40.0%) and 11 cases (8.6%) respectively ( P<0.01); Open surgery were performed in 42 (84.0%) and 42 (33.1%) cases ( P<0.01); Segmental resection of vena cava was performed in 19 cases (38.0%) and 11 cases (8.7%) respectively ( P<0.01). Multivariate analysis showed that Mayo grade Ⅲ-Ⅳ tumor thrombus ( OR=10.261, P=0.006), tumor size > 10 cm ( OR=3.223, P=0.030), open surgery ( OR=5.454, P<0.01) and segmental resection of vena cava ( OR=4.441, P<0.01) were independent risk factors for massive intraoperative bleeding. The median bleeding of Mayo grade Ⅲ-Ⅳ tumor thrombus, tumor size >10cm, open surgery and segmental resection of vena cava were 2000, 750, 1 450 and 1 650 ml respectively. Conclusions:Renal cell carcinoma with tumor thrombus has a high risk of bleeding. Mayo grade Ⅲ-Ⅳ tumor thrombus, tumor size >10 cm, open surgery and segmental resection of vena cava are independent risk factors for massive intraoperative bleeding.
