ABSTRACT
Objective To evaluate the feasibility and clinical significance of radical nephrectomy with en bloc resection of involved adjacent organs.Methods Totally,24 cases of renal cancer invading adjacent structures underwent radical nephrectomy with en bloc resection of involved adjacent organs.Among the 24 cases,left radical nephrectomy with en bloc resection of splenic flexure and descending colon was performed in 7,partial resection of corpus and cauda pancreatis and spleen in 5,solitary splenectomy in 3;right radical nephrectomy with en bloc resection of hepatic flexure of the colon in 4,partial hepatectomy of right lobe and end-piece in 4,duodenectomy of pars descendens in 1.Of these cases,partial resection of the psoas muscle was performed in 5,and partial resection of mesocolon in 7.Postoperatively,9 cases received immunotherapy.Results There was no intraoperative mortality or severe posuoperative complication.Follow-up of 3-240 months was available in 21 cases.The follow-up showed that 1-,3-,5-and 8-year survival rates were 90.5%(19/21),42.9%(9/21),33.3%(7/21) and 19.0%(4/21),respectively.Conclusions Radical nephrectomy remains the treatment of choice in organ-confined stage of renal carcinoma.With careful selection,radical nephrectomy with en bloc resection of adjacent structures is technically feasible.It can obtain the radical excisional effect.Based on our experience,the operation is relatively safe.Complete surgical extirpation can lead to prolonged disease-free survival.It may also offer beneficial foundation for the subsequent systematic therapy.
