- Abstract:
- Objective To explore the preliminary therapeutic efficacy of nephron sparing surgery (NSS) for unilateral Wilms tumor after neoadjuvant chemotherapy. Methods From January 2014 to December 2020,retrospective analysis was conducted for the relevant clinical data of 7 children hospitalized with unilateral Wilms tumor (uWT) receiving neoadjuvant chemotherapy and undergoing NSS.Clinical parameters of tumor recurrence,renal function,and survival rate were recorded.And treatment outcomes were compared with matched cases of radical nephrectomy (RN) during the same period. Results There were 4 boys and 3 girls with an onset age of (38.86±18.23)(16-55) month.There was no tumor-related syndrome or hemihypertrophy.Renal tumor was located at pole (n=1) and center (n=6).After neoadjuvant chemotherapy,tumor shrank by (66.4%±18.6%)(53.3%-93.9%).One child with a pole renal tumor underwent partial nephrectomy (PN) while the remainders tumor enucleation (TE).Postoperative pathological examination indicated that microscopic tumor margins were positive (n=2).According to SIOP staging,the stages were Ⅱ(n=4) and Ⅲ(n=3).During a follow-up period of (38.42±10.17)(27-64) month,no case became lost or died.There were tumor-free survival (n=6) and 1 tumor-bearing survival (n=1).Two cases had tumor recurrence after NSS surgery.No statistically significant difference existed in recurrence rate (28.6%) and 5-year survival rate (100%) after NSS as compared with recurrence rate (13.3%) and 5-year survival rate (86.9%) of RN in the same period. Conclusions For uWT,proper preoperative evaluations and neoadjuvant chemotherapy may boost the proportion of NSS surgery and achieve similar therapeutic outcomes as RN.
