AIM: Urothelial carcinoma (UC) can occur multifocally in the whole urothelium. A higher rate of bilateral metachronous upper tract (UT) UC was noted in Taiwan. The incidence and risk factors were largely unknown and hence were explored in the study. METHODS: From January 1977 through June 2003, 462 patients with unilateral UT-UC were studied retrospectively. The cumulative incidence of contralateral recurrence was analysed with the Kaplan-Meier analysis. Potential risk factors for contralateral recurrence including age, smoking, bladder cancer, renal function, diagnostic year etc. were evaluated with the log-rank test. Independent risk factors were identified by using the Cox regression analysis. RESULTS: The median follow-up time was 34 months (6-337). Among the 462 patients, 52 (11.3%) developed metachronous contralateral UC. The 2, 5, and 10-year contralateral disease-free survivals were 93.5%, 84.0%, and 75.7%, respectively. The median time to contralateral recurrence was 31.0 months. With the univariate analysis, only poor renal function (serum creatinine < or > OR =2.0 mg/dL, P < 0.001) and late diagnostic year (before or after 1990, P < 0.001) were risk factors for contralateral recurrence. In the multivariate analysis, poor renal function (hazard ratio: 2.98; 95% confidence interval: 1.67-5.33; P < 0.001) and late diagnostic year (hazard ratio: 4.27; 95% confidence interval: 1.71-10.65; P = 0.002) remained independent risk factors. CONCLUSIONS: The incidence of metachronous UT-UC is high in Taiwan. Patients who had either chronic renal insufficiency or a disease diagnosed after 1990 had a higher risk of contralateral recurrence. 相似文献

对1971—1990年间加拿大不列颠哥伦比亚癌症中心收治的428例鼻咽癌病人的发病和治疗情况进行分析。其中,中国人占303例(71%),白种人116例(27%)。中国人在该省鼻咽癌的年发病率是白种人的64倍,其中又以在中国出生的发病率最高,分别为白种人的104倍和北美出生的中国人的16倍。本组总的5年和10年生存率分别为51%和39%,颈淋巴结阴性的病人5年生存率达64%;而阳性的病人只有44%。鼻咽癌的预后与它的临床分期、病理类型、治疗前有无做颈淋巴结活检,以及性别有关,而与病人的人种和出生地无关。 相似文献

The incidence, risk factors, and prognosis for Mycobacterium tuberculosis (MTB) infection have not been reported in a national population of renal transplant recipients. We performed a retrospective cohort study of 15,870 Medicare patients who received renal transplants from January 1, 1998 to July 31, 2000. Cox regression analysis derived adjusted hazard ratios (AHR) for factors associated with a diagnosis of MTB infection (by Medicare Institutional Claims) and the association of MTB infection with survival. There were 66 renal transplant recipients diagnosed with tuberculosis infection after transplant (2.5 cases per 1000 person years at risk, with some falling off of cases over time). The most common diagnosis was pulmonary TB (41 cases). In Cox regression analysis, only systemic lupus erythematosus (SLE) was independently associated with TB. Mortality after TB was diagnosed was 23% at 1 year, which was significantly higher than in renal transplant recipients without TB (AHR, 4.13, 95% CI, 2.21, 7.71, p < 0.001). Although uncommon, MTB infection is associated with a substantially increased risk of mortality after renal transplantation. High-risk groups, particularly those with SLE prior to transplant, might benefit from intensified screening. 相似文献

目的 探讨白细胞介素-1受体拮抗剂(interleukin-1 receptor antagonist,IL-1Ra)基因多态性与冠心病患病率及心血管事件发生的关系.方法 利用聚合酶链式反应(PCR)技术对220例冠心病患者及100例正常对照者IL-1Ra基因进行扩增;检测冠心病患者的高敏感性C反应蛋白、血清总胆固醇、甘油三酯、低密度脂蛋白和体重指数;所有冠心病患者随访12个月,了解患者在出院后1年内的心血管事件.结果 冠心病患者和正常人的IL-1Ra基因多态性分布的差别没有统计学意义;出院后未发生心血管事件的冠心病患者Ⅱ型基因型携带率高于其他基因型.结论 监测IL-1Ra基因多态性不能预测冠心病的发生;但其多态性中Ⅱ型基因对已患冠心病患者的预后有一定保护作用. 相似文献

Objective: To explore the trends of incidence and mortality rates of stroke in Hanzhong rural population. Methods: Acting as the WHO MONICA project. Results: The incidence rate of stroke was 152. 9/100 000. There was decline trend in male(P <0. 05). The mortality rate of stroke was 115.9/100 000. There was no significant decline trend during 18-year period (P < 0. 05). The incidence and mortality rates of stroke of male were higher than those of female(P<0. 05). The incidence and mortality rates were all increased with age(P <0. 01 ). Conclusion: It must stick to the long- term prevention measures to decrease incidence rate, and improve the condition of medical treatment to reduce the mortality rate in rural population. 相似文献

Background Prostate cancer is rare in Asia, but the number of patients is increasing in Japan. We conducted an epidemiological study of prostate cancer in Gunma Prefecture, Japan, to investigate the trends and characteristics of the disease.
Methods: The subjects were 1.411 prostate cancer patients newly diagnosed between 1985 and and 656 patients who died from prostate cancer between 1981 and 1992. The incidence and mortality rates were calculated by year, demographic region and age.
Results: The yearly incidence rate showed an increase but the mortality rate showed no marked fluctuations. There was no significant difference between urban and ruraI districts in either incidence or mortality rate. The incidence rate tended to be high in the northern part of the prefecture, but no marked variation in mortality rate was seen. The incidence and mortality rates in districts with a history of manganese mining were high compared to those in districts without mining. In contrast, the incidence and mortality rates in districts with a history of zinc mining were comparatively lower. Both incidence and mortality rates showed a marked increase with age. The age-specific incidence showed a double logarithmic relationship to age.
Conclusions: The increase of the yearly incidence rate might be due to changes in lifestyle and environmental factors, improved diagnostic techniques, and increased awareness among the general public regarding prostate disease. Further investigation is needed to clarify the pattern and the causes of regional differences in the incidence and mortality rates. The possibilities that manganese and zinc might be related to prostatic carcinogenesis are suggested. Int J Urol 1995:2:191–197 相似文献

Evaluation of the long-term health of children born using in-vitro fertilization (IVF) provides important information to clinicians and consumers. Until very recently, there have been no published data on the incidence of cancer in children conceived as a result of IVF, despite a number of case reports of neuroblastoma in children conceived using fertility drugs. This study used a record-linkage cohort design to investigate the incidence of cancer in children born after IVF. The study included all conceptions using assisted reproductive technologies between 1979 and 1995 at two clinics in Victoria, Australia that resulted in a live birth. Data on births were linked with a population-based cancer registry to determine the number of cases of cancer that occurred. The standardized incidence ratio (SIR) was calculated by comparing the observed number of cases to the expected number of cases. The final cohort included 5249 births. The median length of follow-up was 3 years, 9 months (range 0-15 years). In all, 4.33 cases of cancer were expected and six were observed, giving a SIR of 1.39 (95% CI 0.62-3.09). This study found that children conceived using IVF and related procedures did not have a significantly increased incidence of cancer in comparison to the general population. 相似文献
