Outcome of surgery for patients with renal cell carcinoma and tumour thrombus in the era of modern targeted therapy

AbstractObjective: This study evaluated the clinical outcome of patients with renal cell carcinoma (RCC) with tumour thrombus (TT) after surgical management.Materials and methods: In total, 142 consecutive RCC patients with TT who were operated on in Helsinki University Hospital between 2006 and 2014 were analysed. Eighty-eight (62%) of these patients had been operated on with radical intention and 54 (38%) with cytoreductive intention. A total of 73 patients (51%) received postoperative targeted therapy. The primary endpoint was cancer-specific survival (CSS).Results: The 5 year CSS for level of involvement of TT in the renal vein, subdiaphragmatic vena cava and supradiaphragmatic vena cava was 60% (81 patients), 43% (52 patients) and 51% (nine patients), respectively (p = .42). The median CSS for lymph-node involvement was 63 months for patients with no lymph-node involvement but 10 months for patients with lymph-node involvement (p < .01). The median CSS for metastasis status was 63 months for patients...
