Abstract:
Objective To investigate the diagnosis and treatment of cystic renal cell carcinoma.Methods The clinical data of 67 cases of cystic renal cell carcinoma treated from January 2005 to April 2013 were analyzed retrospectively.Preoperative imaging procedures indicated masses of renal cysts in 67 cases,including malignant tumors in 59 cases.Intraoperative pathological examination was performed in 59 cases and the pathological results showed malignant tumors in 56 cases,renal cyst in 2 cases and multilocular cyst of kidney in 1 case.The surgical procedures included radical nephrectomy (n=19),partial nephrectomy (n =12),retroperitoneal laparoscopic radical nephrectomy (n =9),retroperitoneal laparoscopic partial nephrectomy (n =20),retroperitoneal laparoscopic cyst unroofed then transferred to radical nephrectomy (n =6),and retroperitoneal laparoscopic partial nephrectomy transferred to radical nephrectomy (n =1).Results The 67 cases were diagnosed as renal carcinoma,including clear renal cell carcinoma with cystic changes in 31 cases and multilocular renal cell carcinoma in 36 cases.Sixty-two cases were followed up for 10-110 months (median 56 months),and there was no recurrence or metastasis,among which 7 cases diagnosed as benign pre-operation or intra-operation but malignant by pathological examination after surgery were followed up for 61-103 months (median 82 months).Conclusions Imaging plays an important role in the early diagnosis of cystic renal cell carcinoma.Intraoperative pathological examination should be performed in suspected cases.Nephron-sparing surgery is preferred with good outcome.
