欧洲癌症研究与治疗组织风险评分表在非肌层浸润性膀胱尿路上皮癌中的临床应用初探

Objective To evaluate the feasibility of European Organization for Research and Treatment of Cancer (EORTC) risk tables in non-muscle invasive bladder cancer in Chinese patients.Methods A retrospective analysis was performed on the data from 185 patients with non-muscle invaaive urothelial bladder cancer from January 2003 to February 2009. Among the 185 patients, 128 patients were stage Ta compared with 57 patients who were stage T1. There were 87, 53 and 45 patients with grade G1, G2 and G3 respectively. Transurethral resection of the bladder tumor was performed on all the patients and all the patients received routine post-operative intravesical instillation. A telephone interview follow-up was conducted on all the patients, and the average follow-up period was 36 months. EORTC risk tables were used to calculate risk scores for recurrence and progression for each patient. The recurrence and progression rates of different risk groups were recorded and compared with the estimated rates by EORTC risk table. Statistical analysis was used for comparison. ResultsTotal 1-year recurrence rate and progression rate for these patients were 25.9% and 3.8% respectively. According to calculated values of the patients, the 1-year recurrence rates of Group 0, Group 1-4, Group 5-9, Group 10-17 were 10.4%(5/48), 21. 5%(14/65), 35. 2% (19/54), 55.6%(10/18), respectively. The 1-year progression rates of Group 0, Group 2-6, Group 7-13, Group 14-23 were 0% (0/43), 1.5% (1/67), 6. 7% (4/60), 13. 3% (2/15). There was no significant difference between the real rates and estimated rates of the EORTC risk tables (P＞0. 05). However,the 1-year recurrence and progression rates between the low risk group, the medium risk group and the high risk group showed significant differences respectively (P ＜ 0. 05 ). Conclusions The EORTC risk tables are feasible to evaluate the recurrence and progression risk of non-muscle invasive bladder cancer in the present cohort. Nevertheless, the long term value and feasibility need more research to confirm.

欧洲癌症研究与治疗组织风险评分表对国人非肌层浸润性膀胱癌预后判断的意义

Objective To Validate the prognostic significance of the European Organization for Research and Treatment of Cancer (EORTC) risk tables in Chinese patients with non-muscle invasive bladder cancer (NMIBC). Methods According to the scoring standard of the EORTC system, 225 NMIBC patients were reviewed and divided into 3 groups: low, intermediate and high risk groups for recurrence and progression respectively. The probabilities of recurrence and progression at 1 year and 5 year for each group were calculated using life-table analysis and then compared with the EORTC risk tables. Log-Rank test and multivariable analysis were used to analyze the possible differences between risk groups and to find independent prognostic factors. Results For low (n= 32, 25), intermediate (n=109, 128) and high (n=84, 72) risk groups, the probabilities of recurrence and progression at 1 year were 15. 1%, 31.2%, 55.5% and 0. 3%, 2. 0%, 15.5% respectively. The probabilities at 5 year were 28. 2%, 55.2%, 75.0% and 1.4%, 12.9%, 54. 7%. All the results were similar to that of EORTC tables except the probability of progression at 5 year for the high progression risk group.The differences between different risk groups were significant (P＜0.01). In a multivariable analysis for recurrence and progression, the EORTC scores had independent significance (P＜0.01). Conclusions EORTC risk tables could stratify NMIBC patients effectively according to the risk of recurrence and progression. It could be a useful tool for Chinese urologists.

140例胃间质瘤的外科治疗分析

Objective To analyze the outcome of the patients with gastric gastrointestinal stromal tumor (GIST) after surgical treatment and identify the associated risk factors. Methods Clinical data and the tissue slices including immunohistochemistry staining of 140 patients with gastric GIST from January 1990 to December 2008 were retrospectively reviewed. SPSS 16.0 for Windows software package was used for statistical analysis. Results The overall survival rates of 1-, 3-, 5-year were 96.8%,86.7% and 79.3%, respectively. The survival rates of 1-, 3-, 5-year were 98.1%, 90.0% and 85.4% in patients who underwent complete tumor resection. But the survival rates of 1-, 3-, 5-year were 38.1%, 0 and 0 in patients with incomplete tumor resection. The differences were statistically significant (P＜0.05). Gender, preoperative metastasis, tumor size, pathology type, karyokinesis, recurrence and metastasis were associated with survival rates in patients with complete tumor resection by univariate analysis. However, only tumor size, karyokinesis, recurrence and metastasis were associated with survival rates by Cox regression multivariable analysis (P＜0.05). Conclusion Surgery remains the main treatment for gastric GIST. Local complete resection is the principal treatment.

腹腔镜结直肠癌根治术疗效分析

Objective To investigate the efficacy of laparoscopic radical resection for colorectal cancer. Methods From September 2000 to December 2004, 99 patients with colorectal cancer underwent laparoscopic radical resection (laparoscopic group) and 198 patients with colorectal cancer underwent open radical resection (open group) at the Union Hospital of Fujian Medical University. The differences in local recurrence and survival between the two groups were compared. The local recurrence of tumors and survival of patients in the two groups were calculated by the life-table method, and were compared by the Wilcoxon (Gehan) test, chi-square test and Fisher's exact test. The recurrence interval and survival time of the two groups were compared by non-parametric Wilcoxon rank sum test. Results The 2-and 3-year local recurrence rates in the laparoscopic group were both 3.0% and the overall local recurrence rate was 3.0% (3/99). The 2-and 3-year local recurrence rates in the open group were 2.6% and 4.0% , respectively, and the overall local recurrence rate was 3.5% (7/198), with no significant difference between the two groups (χ2 =0.002, P > 0. 05). The median survival time of patients with local recurrence was 15 months (range, 7-24 months) in the laparoscopic group and 11 months (range, 2-28 months) in the open group, with no significant difference between the groups (U = 15. 500, P >0. 05). The 1-year survival rate was 33.3% in the laparoscopic group and 42.9% in the open group. The 2-year survival rate was zero in the laparoscopic group and 42. 9% in the open group. There were no significant differences between the groups for the 1-and 2-year survival rates (χ2 =0.120, P>0.05). Conclusions The efficacy of laparoscopic radical resection for colorectal cancer is similar to that of open surgery. Laparoscopic radical resection for colorectal cancer is safe and feasible, and does not increase the recurrence rate of cancer.

维生素K2预防肝癌根治术后肿瘤复发

Objective To study the preventive effects of vitamin K2 on tumor recurrence in patients with hepatocellalar carcinoma (HCC) after radical resection. Methods The clinical data of 50 patients with HCC who received radical resection from March 2006 to March 2007 in No. 181 Hospital of PLA were analyzed retrospec-tively. All the patients were divided into 2 groups according to the random number table. Twenty-six patients in vitamin K2 group were administered with menatetrenone (45 mg per day), and the rest 24 pateints were in the control group. The accumulative and tumor-free survival rates, differences between the 2 groups, multivariate factors for prognosis were analyzed by Kaplan-Meier curve, Log-rank test and Cox regression model, respectively. Results During a period of 36 month follow-up, 10 patients died and 28 had tunor recurrence. The 1-, 2-, 3-year accumulative survival rates were 96%, 92% and 83% in vitamin K2 group, and 96%, 82% and 63% in control group (χ2 = 3.61, P > 0.05). The 1-, 2-, 3-year tumor-free survival rates were 92%, 60% and 38% in vitamin K2 group, and 75%, 42% and 12% in control group, with significant difference between the 2 groups (χ2 =5.61, P <0.05). Univariate and multivariate Cox proportional hazard analysis showed that without taking menate-trenone, the preoperative level of alpha fetoprotein (AFP) ≥800 μg/L and vascular invasion were the indepen-dent risk factors for tumor recurrence. Conclusions Vitamin K2 has a suppressive effect on tumor recurrence of HCC, while patients with AFP≥800 μg/L before operation or with vascular invasion have poor prognosis.     

EORTC风险量表对非肌层浸润性膀胱癌术后即刻灌注化疗预后判断的研究

目的：验证和研究欧洲癌症研究与治疗组织（European Organization for Research and Treatment of Cancer,EORTC）风险量表对我国接受术后即刻膀胱灌注化疗的非肌层浸润性膀胱癌（nonmuscle invasive bladder cancer,NMIBC）患者预后判断的效果。方法：回顾性分析2003年5月～2010年12月期间297例接受经尿道膀胱肿瘤电切（transurethral resection of bladder cancer,TURBT）的NMIBC患者的临床病理资料,所有患者均在术后24小时内接受了首次膀胱灌注化疗。按照EORTC量表的评分原则计算出每位患者的复发和进展评分,并根据得分将所有患者进行风险分层。随访各危险组患者术后复发和进展情况,并将分析结果同量表参考值比较。结果：随访时间23～115个月,平均53个月。随访过程中共122例患者（41％）复发,多因素分析显示复发性肿瘤、G2～3级肿瘤和未在TURBT后6小时内进行首次膀胱灌注化疗是复发的独立危险因素;19例患者（6％）术后进展,独立危险因素包括复发性肿瘤、T1期肿瘤、G3期肿瘤和同时存在原位癌。根据EORTC量表进行复发风险分层后,各组间实际复发率差异均有统计学意义（P〈0．01）;与EORTC量表参考值相比,低危组（0分）1年及5年复发率均低于参考范围;中危患者（1～9分）的1年复发率低于参考范围,而5年复发率与参考范围相近;高危组（10b17分）1年及5年复发率可信区间均包含EORTC量表的参考范围。进展风险分层除低危组（0分）与中低危组（2～6分）间的实际进展率差异无统计学意义（P=0．10）外,其它各组问的差异均有统计学意义（P〈0．01）;各风险组实际进展率均接近EORTC的参考范围。结论：EORTC量表对于接受术后即刻膀胱灌注化疗的中国NMIBC患者具有预后价值,但低危患者的实际复发率和中危患者的短期实际复发率低于该量表的参考值。     

Clinical outcome of tumor recurrence for Ta, T1 non-muscle invasive bladder cancer from the data on registered bladder cancer patients in Japan: 1999–2001 report from the Japanese Urological Association

Objective:   To characterize the clinical outcome in a large contemporary series of Japanese patients with newly diagnosed Ta, T1 non-muscle invasive bladder cancer who underwent transurethral bladder tumor resection with or without intravesical chemotherapy or Bacillus Calmette-Guérin (BCG) therapy.
Methods:   We developed a database incorporating newly diagnosed non-muscle invasive bladder cancer data and outcomes from a Japanese bladder cancer registry between 1999 and 2001 and identified a study population of 3237 consecutive patients who had complete data based on pathological features. Median patient age was 69.9 years.
Results:   The 1-year, 3-year, and 5-year overall recurrence-free survival rates were 77.0%, 61.3%, and 52.8%, respectively. In multivariate analyses, the multiplicity of bladder tumors, tumor size greater than 3 cm, pathological stage T1, tumor grade G3, and the absence of adjuvant intravesical instillation were independent risk factors for tumor recurrence. Overall, 1710 patients (52.8%) received intravesical instillation; chemotherapy in 1314 (76.8%) and BCG treatment in 396 (23.2%). In patients treated with intravesical chemotherapy in which an anthracycline chemo-agent was used in 90.5% of the cases, multivariate analyses demonstrated that male gender, multiple bladder tumors, a tumor size greater than 3 cm, and pathological stage T1 were associated with tumor recurrence.
Conclusions:   The accumulation and analysis of data from the Japanese National Bladder Cancer Registry made it possible to determine the clinical characteristics, management trends, and survival rates for the period studied. Further study with a dataset created from longer follow-up data would be warranted to analyze tumor progression and disease survival.

Correlación entre el índice neutrófilo/linfocito y las puntuaciones de riesgo en el cáncer de vejiga no músculo-invasivo

ObjectivesAim of this study is to evaluate the correlation between European Organization for Research and Treatment of Cancer (EORTC) risk score and neutrophil-lymphocyte ratio (NLR) in patients with non-muscle invasive bladder cancer and the relationship between NLR and risk groups.MethodsWe retrospectively reviewed data of 212 patients with non-muscle invasive bladder cancer were included in the study. The tumors were graded according to the 1973 World Health Organization grading system and the tumor node metastasis (TNM) 2012 staging system. Patients were categorized low, intermediate and high risk for recurrence and progression, according to European Association of Urology guidelines. Serum values for the NLR were measured on the day before the operation to ascertain the baseline value for neutrophil and lymphocyte counts and statistically analyzed.ResultsOf the 212 patients, 193 were male and 19 were female. Mean age was 66.7. Mean NLR score was 3.04 ± 2.11. T1 tumors, G3 tumors, multiple tumors and > 3 cm tumors seen mostly in patients with NLR > 2.41. Low, intermediate and high risk groups compared and NLR rates were significantly higher in high risk group patients (P < .001). When the correlation between NLR and EORTC recurrence and progression scores was evaluated, it was observed that as NLR value increased, recurrence (r = 0.252, P < .001) and progression (r = 0.145, P = .034) scores increased significantly.ConclusionsThis study demonstrated the association of high NLR value with T1 tumor, high grade, multiple tumor, > 3 cm tumor and EORTC high risk group in non-muscle invasive bladder cancer patients.

目的 分析T1G3膀胱癌的临床特点及复发、进展、死亡的风险因素,提高对T1G3膀胱癌的认识和治疗效果. 方法 收集1998年1月至2006年10月天津市泌尿外科研究所诊断为T1G3膀胱癌且资料完整的患者187例.男162例,女25例.年龄35～92岁,平均66岁.进行临床流行病学调查并随访预后情况.寿命表法估计1、2、3、5年复发率、进展率及死亡率.将年龄、性别、出现症状至就诊时间、有无肾积水、手术方式、术后是否即刻灌药、膀胱灌注药物种类、肿瘤直径、肿瘤数量、肿瘤形态、有无原位癌、复发次数、初次复发时间≤6个月作为变量,分别进行肿瘤复发、疾病进展、死亡的Kaplan-meier单因素及Cox多因素生存分析. 结果 本组患者随访12～111个月,平均46个月.肿瘤复发100例(53.5％),进展61例(32.6％),死亡37例(19.8％).1、2、3、5年肿瘤复发率分别为35.0％、60.0％、63.0％、65.0％,疾病进展率分别为12.0％、27.0％、34.0％、38.0％,死亡率分别为0、11.0％、17.0％、26.0％.肿瘤直径、肿瘤数量、即刻灌注、初次复发时间≤6个月是T1G3膀胱癌复发的危险因素;肿瘤形态、原位癌、初次复发时间≤6个月、复发次数是T1G3膀胱癌进展的危险因素.肿瘤进展是患者死亡的危险因素. 结论 肿瘤直径≥3 cm、多发、初次复发时间≤6个月的T1G3膀胱癌患者更容易复发,应加强随访,即刻膀胱灌注可以降低T1G3膀胱肿瘤复发的风险.对肿瘤形态呈结节状、合并原位癌、初次复发时间≤6个月、多次复发等进展高危风险因素的T1G3膀胱肿瘤患者,应早期行膀胱切除.     

肿瘤危险因素评分对非肌层浸润性膀胱肿瘤预后判断的价值（附248例报告）

目的：评价膀胱肿瘤复发及进展评分对非肌层浸润性膀胱肿瘤预后判断的价值。方法：收集自2006年7月～2010年3月于我院接受腔内治疗的248例T0和T1期膀胱肿瘤患者临床资料,记录肿瘤数量、肿瘤大小、肿瘤临床分期、病理级别、既往有无肿瘤复发及有无伴随原位癌等相关资料,以EORTC（The European Organization for Research and Treatment of Cancer）肿瘤风险评分表对患者评分,随访术后患者肿瘤复发及进展情况。结果：本组肿瘤复发危险评分为O～15分,平均（4．37±2．93）分;肿瘤进展危险得分为0～23分。平均（5．21±3．95）分。随访3～60个月,平均（25．8±18．5）个月,共有123例（49．6％）肿瘤复发,平均（11．4±6．5）个月。87例（70．7％）于1年内肿瘤复发,36例（29．3％）复发超过1年。24例（19．5％）肿瘤进展[平均（9．8±6．2）个月]。复发评分0～2分者肿瘤复发不足20％,进展评分0～2分者肿瘤无进展。3分者肿瘤进展率为6．1％。肿瘤数量是肿瘤复发与进展的首要危险因素,相对危险度分别为2．229和5．246。结论：肿瘤复发及进展评分可简便准确地判断非肌层浸润性膀胱肿瘤患者预后,但仍有修改与完善的必要。     

高危非肌层浸润膀胱尿路上皮癌术后再活检和电切的临床意义

目的 探讨术后再活检和电切术可否减少高危非肌层浸润膀胱尿路上皮癌的复发和进展.方法 高危非肌层浸润膀胱尿路上皮癌123例,经尿道电切术后4～6周进行再活检或电切52例,同期未行再次电切而常规随访71例,比较2组患者肿瘤复发和进展情况.结果 再活榆或电切的52例中,发现残存肿瘤28例(54%),其中肌层浸润肿瘤5例,行膀胱全切治疗2例、患者拒绝行膀胱全切3例.随访12～43个月,中位时间27个月,肿瘤复发24例(48%),进展为肌层浸润肿瘤10例(20%);常规随访组肿瘤复发49例(69%),肿瘤进展23例(32%).2组患者肿瘤复发率比较差异有统计学意义(P<0.05),肿瘤进展率比较差异无统计学意义(P0.05).结论 首次电切术后再活检和电切可以降低高危非肌层浸润膀胱尿路上皮癌的复发率,但不能减少肿瘤进展的风险.
