Abstract:
Objective To investigate the efficacy of 125I radioactive particle implantation combined with surgery and chemotherapy in the treatment of locally advanced urinary tract urothelial carcinoma (UTUC).Methods The clinical data of 128 patients of locally advanced (T3,T4) UTUC treated with surgery with radioactive particle implantation plus postoperative GC chemotherapy (experimental group) and surgery plus postoperative GC chemotherapy (control group) were retrospectively analyzed.All the patients underwent complete resection of the tumor.The postoperative pathology was urinary tract epithelium cancer.In the experimental group,there were 45 (69.2％) males and 20 (30.8％) females,with median age 56.5 years.There were 39 (60.0％) patients diagnosed with renal pelvic cancer,including 13 (33.3 ％) patients with local lymph node metastasis;26 patients (40.0％) with ureteral cancer,11 patients (42.3％) with local lymph node metastasis.In the control group,there were 46 males (73.0％) and 17 females (27.0％),with median age 57.1 years.There were 40 (63.5％) patients with renal pelvic cancer,including 12 (30％) cases of local lymph node metastasis;23 patients with ureteral carcinoma (36.5％),including 10 patients (43.4％) with local lymph node metastasis.There was no significant difference in basehne data between the two groups (P ＞ 0.05).The recurrence and distant metastasis,recurrence-free survival,distant disease free survival(DDFS),disease-specific survival(DSS),overall survival (OS) and comphcations of two groups were compared.Results The follow-up time was 50.5 months (ranged 5 to 62 months).In experimental group,there were 2 cases,5 cases,11 cases,16 cases and 21 cases occurred recurrence and distant metastasis in 6 months,1 year,2 years,3 years and 5 years respectively,and the 5-year cumulative recurrence and distant rate was 32.3％ (21/65).In control group,there were 3 cases,5 cases,17 cases,21 cases and 32 cases,occurred recurrence and distant metastasis in 6 months,1 year,2year,3 year,5 year respectively,and the 5-year cumulative recurrence and distant rate was 50.8％(32/63).There was significant difference between the two groups (P =0.034).In the experimental group and the control group,the 5-year non-metastatic survival rates were 61.5％ (40/65)and 41.3％ (26/63),respectively.There was significant difference in 5-year non-metastatic survival rate between the two groups (P =0.033).The 5-year DSS rates were 69.2％ (45/65) and 50.8％ (32/63),respectively.The 5-year DSS rate of the two groups was significantly different (P =0.033).The 5-year OS rates were 53.8％ (35/65) and 36.5％ (23/63) respectively.There was significant difference in the 5-year OS rate between the two groups (P =0.049).Condusions Compared with surgery and chemotherapy,the use of 125I radioactive particle implantation combined with surgery and chemotherapy in the treatment of locally advanced stage (T3-T4) UTUC could achieve the total survival benefit,and less adverse reactions.
