[Clinical analysis of renal cell carcinoma: report of 271 cases].

OBJECTIVE

To study the diagnosis and treatment of renal cell carcinoma.

METHOD

From January 1993 to December 2000 the data of 271 cases of renal cell carcinoma were reviewed.

RESULTS

Ultrasonography and CT scanning were still the main diagnostic methods. Surgical operation was performed on 234 patients. Radical nephrectomy was performed on 197 patients (72.6%); Nephron sparing surgery was performed on 19 patients; Metastatic tumor resection was performed on 6 patients and other procedures for 12. The pathological results showed that 137 cases (61.4%) were clear cell carcinoma, 18 cases (8. 1%) of granular cell carcinoma, 32 cases (14. 3%) being combination of the above two varieties, 23 cases (10.3%) of renal papillary adenocarcinoma, 13 cases being renal cell of other types. And 210 cases (77.5%) had been successfully followed up. The 1, 3, 5 and 10 year survival rates were 95.3% (182/191), 88.7% (107/122), 74.7% (56/75) and 32.1% (10/31) respectively.

CONCLUSIONS

Ultrasonography is the first select examination method of detecting of renal cell carcinoma, and CT scanning is the most valuable diagnostic mean. Early diagnosis and prompt radical nephrectomy or nephron sparing nephrectomy are the critical points for achieving long-term survivals of patients with renal cell carcinoma.
