ABSTRACT

Objective:To investigate the 2 years’ efficacy of intravesical instillation of domestic BCG versus epirubicin in the prevention of recurrence of intermediate-risk or high-risk non-muscular invasive bladder cancer and predictive factors of BCG instillation.Methods:From July 2015 to June 2020, 18-75 years old patients with moderate to high-risk non muscle invasive bladder cancer (NMIBC) confirmed by pathological examination were involved. The ECOG score was 0-2. Exclusion criteria included ①immune deficiency or impairment (such as AIDS), using immunosuppressive drugs or radiotherapy, suspected allergic to BCG or epirubicin or excipients of the two drugs, fever or acute infectious diseases including active tuberculosis or receiving anti tuberculosis treatment, with severe chronic cardiovascular and cerebrovascular diseases or chronic kidney disease; ②combined with other urogenital system tumors or other organ tumors; ③combined with muscle invasive bladder urothelial carcinoma (≥T 2); ④undergoing chemotherapy, radiotherapy or immunotherapy within 4 weeks (immediate instillation after surgery not included); ⑤ pregnant or lactating women; ⑥ comfirmed or suspected bladder perforation; ⑦gross hematuria; ⑧cystitis with severe bladder irritation that may affect the evaluation; ⑨participat in other clinical trials within 3 months; ⑩alcohol or drug addiction; ?any risk factors that may increasing the risk of patients. Epirubicin 50 mg was irrigated immediately after the operation(TURBT or laser resection). The patients were randomly divided into BCG15 group, BCG19 group and epirubicin group by the ratio of 2∶2∶1, and the patients were maintained intravescical instillation for 1 year. The recurrence and adverse events of the three groups were compared. Univariate and multivariate analysis was performed to predict the risk factors of BCG irrigated therapy failure. Result:By June 15, 2020, the median follow-up duration was 22.1 months(12.1, 32.3), and there was no statistical difference between the groups ( P=0.9024). There were 274 patients enrolled in BCG19 group, 277 patients enrolled in BCG15 group and 130 patients enrolled in the epirubicin group. The drop-off rate was 16.6%(113 cases)and made no difference between groups( P=0.6222). There were no significant difference in age, gender, BMI, or ECOG score( P>0.05). During the follow-up, 116 cases was detected recurrence or progression. The recurrence rate of the three groups was 14.2% and 14.8% in BCG19 group and BCG15 group, and 27.7% in the epirubicin group. There was no difference in recurrence rate between BCG19 and BCG15 group( P=0.9464). The recurrence rate of BCG19 group was lower than that of the epirubicin group ( P=0.0017). The recurrence rate of BCG15 group was lower than that of the epirubicin group ( P=0.0020). There was no difference in the cumulative recurrence free survival rate between BCG19 and BCG15 group (95% CI0.57-1.46, P=0.7173). The cumulative recurrence free survival rate of BCG 19 group was better than that of the epirubicin group( HR=0.439, 95% CI0.26-0.74, P=0.0006), and the cumulative recurrence free survival rate of BCG15 group was better than that of the epirubicin group ( HR=0.448, 95% CI0.29-0.80, P=0.0021). The total incidence of adverse events in 19 BCG19, BCG15 and epirubicin group were 74.5%, 72.6% and 69.8% respectively. There was no difference in the incidence of adverse events between BCG19 and BCG15 group( P=0.6153). The incidence of adverse events in epirubicin group was lower than that of BCG19( P=0.0051) and BCG15( P=0.0167) groups.There was no significant difference in the incidence of serious adverse events (SAE) among the three groups ( P=0.5064). Log rank test univariate analysis and Cox risk regression model multivariate analysis showed that the history of bladder cancer recurrence( HR=6.397, 95% CI1.95-20.94, P=0.0001)was independent risk factor for BCG irrigation failure. Conclusions:The 2 years’ efficacy of intravesical instillation of domestic BCG is better than than of epirubicin with good tolerance and safety. There is no difference between BCG19 and BCG15 group. BCG doesn’t increase SAE compared with epirubicin. Recurrence status was an independent prognostic factor regarding recurrence-free survival.

ABSTRACT

Objective To investigate the efficacy and safety of intravesical instillation of BCG vaccine in the prevention of early recurrence of middle and high risk non-muscle invasive bladder cancer.Methods From July 2015,patients with non-muscle invasive bladder cancer aged 18-75 years with informed consent were screened and underwent transurethral resection of bladder tumor (TURBT).Immediately intravesical instillation of epirubicin 50 mg was given postoperatively.After pathology was comfirmed,patients was enrolled in group 1 (BCG15) or group 2 (BCG 19) or the control group (epirubicin 18) randomly with SAS 9.3 software.Data of follow-up and Adverse event was collected and analyzed.Results By May 31,2019,531 patients were enrolled in the study.The drop-off rate was 20.1%.167 patients (143 males and 24 females)in group 1,172 patients (141 males and 31 females)in group2 and 84(75 males and 9 females) in the control group with follow-up data were analyzed.There were no significant differences in age,gender,BMI,ECOG score,risk stratification between the three groups (P =0.8641,P =0.2906,P =0.9384,P =0.6126).The median follow-up time makes no statistical difference between the groups (P =0.9251),12.0 (6.0,22.5) months,13.0 (6.0,22.3) months,and 13.0 (7.0,22.3) months.The median recurrence time of the three groups was 4.0 (3.0,6.0) months,4.5 (3.0,9.8) months,4.5 (3.0,8.8) months.There was no statistical difference between the three groups (P =0.2852).Risk stratification in the patients got no significant difference between the three groups (P > 0.05).The 1-year recurrence-free survival rates were 80.0% in the group 1 and 88.3% in the group 2 and 73.7% in the control group.The group 2 was superior to the group 1 and the control group (P =0.0281,P =0.0031).There was no significant difference between group 1 and control group (P =0.2951).There was no significant difference in the cumulative recurrence-free survival between the experimental group 1 and the experimental group 2,(95% CI 0.80-2.43,P =0.2433).The cumulative recurrence-free survival in the group 1 and the group 2 was better than the control group (95 % CI 0.31-0.92,P =0.0266;95 % CI 0.20-0.65,P =0.0008).All the cases underwent instillation were analyzed for adverse events.The incidence of overall AE(adverse events) in group 1 was 68.5% (152/222),the incidence of grade Ⅰ-Ⅱ AE was 53.2% (118/222),the incidence of grade Ⅲ-Ⅳ AE was 15.3% (32/222).The incidence of overall AE in the group 2 was 71.8% (160/223),the incidence of grade Ⅰ-Ⅱ AE was 60.1% (134/223),and the incidence of grade Ⅲ-Ⅳ AE was 11.7% (26/223).The overall AE rate in the control group was 53.2% (59/111),of which the incidence of grade Ⅰ-Ⅱ AE was 42.4% (47/111),and the incidence of grade Ⅲ-Ⅳ AE was 10.8% (12/111).There was no difference in the incidence of overall AE between the group 1 and the group 2 (P =0.4497).The incidence of AE in the two experimental groups was higher than that in the control group (P =0.0062,P =0.0008).There was no difference in the incidence of grade Ⅲ-Ⅳ AE between the three groups (P =0.3902).Conclusions BCG(19 instillation schedule) has a better effect on preventing recurrence after 1 year of bladder surgery,which is superior to epirubicin group.The long-term efficacy of BCG in preventing recurrence and the efficacy of different schedules need to be further followed up.The lower urinary tract symptoms,which are mainly urinary frequency,are one of the causes of case fallout and should be fouced in future.Compared with epirubicin,BCG perfusion does not increase the incidence of grade Ⅲ-Ⅳ adverse reactions,and is safe to use.

ABSTRACT

OBJECTIVE To establish an modified model of osteonecrosis in the rat and observe the clinical, pathological and imaging manifestations dynamically. METHODS Healthy male SD rats were divided into 5 groups randomly, including the control group (N, 8 rats), and radiation groups (a, b, c and d, 6 rats each group). For radiation groups, the left mandible of each rat was irradiated at doses of 7.0 Gy for 5 fractions, other rats were sham irradiated, serving as control groups.7 days after irradiation, the left mandibular molars of all rats were extracted. The radiation groups rats were sacrificed at 7, 14, 21, 28 days after irradiation randomly, the 2 rats in control group were sacrificed respectively. All the rats' mandibles were taken and examined by clinical manifestation and Micro-CT and histology methods. The data was analyzed with SPSS 18.0 software package. RESULTS In clinical observation, ulcers were seen in the irradiated site at the 7th day, after then, alopecia, occlusion disorder, and pus discharged from buccal side were seen. Weight loss rightly after radiation and weight gain were seen at the 14th day. In pathological observation, marrow cavity changed first. Many adipose cell was first seen at the 7th day, and inflammations, necrosis, and fibrosis were found in medulla in the irradiated groups after that. Significant increment of empty lacunae and decrement of osteocytes were observed in all irradiated groups at the 7th day. Necrotic bone of the irradiated mandible was only found at the 28th day. Lack of new bone formation within the socket was seen in the Micro-CT three-dimensional at 28th day, and there are no more changes at the early-stage in this model. CONCLUSION An modified rat model of osteoradionecrosis was successfully established, which can shorten experimental period, and this model early stage and deserved to be further researched. Can be used to observe clinical, pathological and imaging magnification, which play a basic role in the protection in early stage and deserved to be further researched.

ABSTRACT

Objective:To study the levels of TNF ? in serum and in urine and IL 6 in serum of renal allograft recipients with acute rejection, infection and CsA induced nephrotoxicity.Methods:The sequential monitoring of TNF ? and IL 6 was conducted by ELISA technique in 106 patients before and after renal transplantation.Results:The levels of IL 6 and TNF ? increased in the first day posttransplant, decreased and stabilized after 1 to 2 weeks, and increased 1 to 3 days prior to the clinical diagnosis in acute rejection, then decreased with effective treatment. IL 6 and TNF ? increased in serum in infection and had no difference in urine. TNF ? in serum and in urine and IL 6 in serum had no significant difference in CsA induced nephrotoxicity.Conclusion:It suggests that the sequential monitoring of IL 6 and TNF ? of renal allograft recipients can be used to estimate the function of graft, as markers of the early diagnosis of acute rejection.
