Partial nephrectomy may be linked with a decreased time-to-death of any cause, according to a recent Cochrane review of a randomized trial involving 541 individuals. It appears to result in little to no difference in surgery-related mortality, cancer-specific survival, and time-to-recurrence.
The study randomly assigned participants with localized kidney tumors that were thought to be cancerous to either partial or radical nephrectomy. Investigators followed them for an average of just over 9 years. Among the results:
- Patients who had only the tumor taken were more likely to die from any cause than those who had the tumor and whole kidney removed.
- There was little to no difference in the time until the tumor came back or in the risk of serious complications resulting in death.
- There was no evidence between the 2 groups regarding the need for hemodialysis.
- Quality of life was also similar in the 2 contingents.
