Renal cell carcinoma with IVC and atrial thrombus: a single centre's 10 year surgical experience.

Unlabelled: Renal cell carcinoma (RCC) propagates into the IVC in 4% of cases with 1% extending into the right atrium. Radical surgical resection remains the definitive curative/palliative treatment in those without significant metastases. The aim was to review our experience in patients with different levels of IVC involvement, cardiopulmonary bypass (CPB) and perioperative/long term outcomes.

Patients And Methods: From 2001 to 2012, 24 radical nephrectomies with IVC thrombectomy were performed. A retrospective chart review was undertaken to record demographics, presenting symptoms, duration of surgery, peri-operative transfusion, CPB and peri-operative complications, tumour grade/stage, and patient survival.

Results: We identified 24 patients (18 male, Age median 59 range 35-78). The commonest presenting symptoms were weight loss, pain and haematuria. The majority of tumours were right sided (n = 17) with 8 having lung metastases at presentation. Thrombus level was 16 (infradiaphragmatic), 2 (supradiaphragmatic), 6 (intra-atrial). 15 patients required sternotomy for vascular control and 9 required CPB both with a significantly longer operative time compared (6.1 ± 3.5 vs. 7.2 ± 1.2 vs. 3.5 ± 1.1 h, respectively). Peri-operative complications (n = 21) included cardiopulmonary, renal, gastrointestinal and septic problems. There were 2 peri-operative deaths. Blood transfusion was significantly less in those not requiring sternotomy or CPB using the "Cell Saver" device. The majority were Fuhrman grade 3 (n = 16) and clear cell type (n = 14). Overall 3-year survival was 100% (Laparotomy only), 40% (sternotomy + cross-clamp), and 20% (CPB).

Conclusions: IVC thrombectomy has significant morbidity and requires careful patient selection and a multi-disciplinary approach to optimise patient outcomes. In this series, the level of IVC thrombus and requirement for CPB directly affects patient morbidity and outcome.
