ABSTRACT
BACKGROUND:
Vena cava (VC) involvement in kidney tumors occurs in 4 to 10% of cases, and is associated with a higher mortality. Nephrectomy with thrombectomy of the VC, performed by a multidisciplinary team, improves survival.AIM:
To report a series of consecutive nephrectomies with caval thrombectomy performed in an academic center. PATIENTS ANDMETHODS:
We report 32 patients with cT3b and 3c renal tumors, who underwent radical nephrectomy with VC thrombectomy between 2001 and 2021. A descriptive analysis of clinical, surgical and pathological variables was performed. Overall survival (OS) and cancer-specific survival (CSS) was calculated using Kaplan-Meier curves.RESULTS:
The mean tumor size was 9.7 cm. According to Mayo classification 3/32 (9%) patients had a type I thrombus, 10/32 (31%) had a type II thrombus, 8/32 (25%) had a type III thrombus, and 5/32 (16%) had a type IV thrombus. The mean bleeding was 2000 cc. There was one intraoperative death. Nineteen percent of patients had complications >= 3 according to Clavien-Dindo classification. Reoperations occurred in 9%. Pre and postoperative creatinine levels were 1.17 and 1.91 mg/dl respectively (p < 0.01). Pre and postoperative Hematocrit levels were 47.9 and 31% respectively (p = 0.02). Sixty six percent of tumors were clear cell renal cancer, 9% were papillary and 3% were chromophobic. Mean OS was 10 months. Two-year SCE was 40%.CONCLUSIONS:
Our results are similar to those reported elsewhere. Despite being an unusual pathology, the surgical technique has been improving, thanks to the multidisciplinary work of urologists and surgeons.
