Surgery and toceranib for renal cell carcinoma with caval thrombus in a dog.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A 14-year-old spayed female papillon dog was presented with hematuria and a right renal mass. Contrast-enhanced computed tomography revealed a tumor thrombus extending about 1.5 cm cranially from the right renal vein into the caudal vena cava (CVC), consistent with renal cell carcinoma and caval thrombus, with no signs of distant metastasis. The dog underwent open right-sided nephrectomy and CVC thrombectomy, using 2 tourniquets, with a total occlusion time of 12 min 13 s. Transient hypotension during surgery was successfully managed, and there were no major intra- or postoperative complications. Histopathology confirmed a highly malignant renal cell carcinoma with vascular invasion. Adjuvant toceranib therapy was initiated to address potential microscopic residual disease. Pulmonary metastasis was detected on Day 553 after surgery, and the dog remained alive on Day 722. This case demonstrates that renal cell carcinoma with caval thrombus in dogs can be surgically managed without severe complications. Moreover, adjuvant toceranib therapy can be used safely. Together, these findings offer valuable insights into the feasibility and safety of surgical strategies for CVC-invasive renal tumors in dogs. Key clinical message: Renal cell carcinoma with caval thrombus in dogs can be safely managed with surgery, highlighting the feasibility of aggressive surgical intervention for this rare condition.
