Abstract:
Objective To discuss the characteristics of renal cell carcinoma with regional lymph node metastasis at diagnosis. Methods The data of 19 patients diagnosed with renal cell carcinoma with regional lymph node metastases at diagnosis from January 2004 to December 2008 were reviewed.The median age was 57 years (29-77).The study group included 15 males and four females.The primary tumor was located in the left kidney in 12 patients and fight in seven patients.The median maximam diameter of retroperitoneal lymph nodes was 2.8 cm(1.5-5.0).The lymph nodes in four patients were not detected by the preoperative image examination,but were confirmed by intraoperative exploration.Eleven cases had enlarged retroperitoneal lymph nodes resected and eight had regional lymph nodes dissected. Results The patients with regional lymph node metastases at diagnosis of renal celI carcinoma accounted for 1.6% (19/1213) of the total renal cell carcinoma cases.With a median follow-up of 34 months,six patients were survival without progression,and seven were survival with progression.giving a 5-year survival rate of 68.4%.The survival and recurrence rates after surgery were not significantly different by Fisher test(P=0.644 and 0.319 respectively) between the patients who underwent retroperitoneal regional lymph node dissection and those who underwent enlarged lymph node resection. Condmiom Renal cell carcinoma with regional lymph node metastasis at diagnosis is uncommon.Some patients may achieve long-term tumor-free survival through regional lymph node dissection or enlarged Iymph nodes resection.
