Primary Institution: Rosewell Park Memorial Institute
Hypothesis
How many cancer cells are released into the renal vein during radical nephrectomy for renal cancer?
Conclusion
Despite a high number of cancer cells released into the renal vein, only a few patients developed distant metastases.
Supporting Evidence
- Cancer cells were detected in 8 out of 10 patients.
- Wide variations in the number of circulating cancer cells were observed.
- Only 3 out of 10 patients had detectable metastases prior to surgery.
Takeaway
Doctors found cancer cells in the blood of patients' kidneys during surgery, but not many of those cells turned into tumors later.
Methodology
Blood samples were taken from the renal vein of patients and cancer cells were isolated using density gradient centrifugation and identified with immunocytochemical techniques.
Limitations
The study may underestimate the total number of circulating cancer cells due to previous methodological issues in earlier studies.
Participant Demographics
Patients undergoing radical nephrectomy for primary renal cancer.
