Abstract

Background About 4-10% of patients with renal cell carcinoma (RCC) demonstrate intracaval tumor thrombi at the time of diagnosis. Furthermore, 2-3% of patients might develop local relapses of which intracaval recurrences represent a rare event with fewer than 15 cases reported in the literature. We report the diagnosis, surgical technique, perioperative complications, and oncological outcome in an additional 6 cases. Patients and methods Between 2008 and 2019, 6 patients were treated with isolated intracaval relapse of RCC. All patients had undergone radical nephrectomy with thrombectomy in the past. The mean time between first surgery and relapse was 45.2 (6-114) months and the mean age of patients was 75 (70-80) years: 2, 3 and 1 patient demonstrated thrombus level II, III, and IV, respectively. A thoracoabdominal and a transperitoneal surgical approach was chosen in 4 and 2 patients, respectively. Perioperative complications were reported according to the Clavien-Dindo classification. Relapse-free, cancer-specific and overall survival were calculated with the Kaplan-Meier method. Results The cava thrombus could be resected completely in all cases. The mean time of surgery was 330 (260-510) min and the mean blood loss was 1500 (300-6500) ml. Clavien-Dindo grade II and IV complications developed in 2 and 1 patients, respectively. The 90-day readmission rate and mortality were 0%. After a mean follow-up of 32.3 (6-96) months, 5 patients are relapse-free and 1 patient developed pulmonary and hepatic metastases managed by immuno-oncological therapy. One patient died 27 months postoperatively due to multiple myeloma. Conclusion Secondary thrombectomy for isolated intracaval tumor thrombus relapse represents a challenging surgery which is associated with a high oncological control rate and tolerable surgery-related morbidity. This type of surgery should be performed in centres with significant expertise in radical nephrectomy for locally advanced disease and thrombus surgery.
