Expression and prognostic significance of survivin in the progression of bladder transitional cell cancer
      
The expression of survivin, a member of inhibitor of apoptosis (IAP) family, was examined in bladder transitional cell cancer (BTCC) tissue and adjacent normal tissues to examine its clinical implication in the development of BTCC.
      
It has been suggested that progression of bladder transitional cell cancer (BTCC) may be regulated at the molecular level by a typical pattern of expression of genes involved in apoptosis.

  transitional cell carcinomas
The primary role of immunotherapy for bladder cancer is to treat superficial transitional cell carcinomas (ie, carcinoma in situ, Ta, and T1).
      
In addition, p53 mutations and loss of heterozygosity on various chromosomes have recently begun to shed light on the molecular pathways of transitional cell carcinomas of the bladder.
      
Human papillomavirus type 16 associated with multifocal transitional cell carcinomas of the bladder in two transplanted patients
      
This report describes two cases of rapidly progressive, multifocal transitional cell carcinomas of the bladder that developed in two patients after renal and cardiac transplantation, respectively.

We report on the pathological findings in a case of moderately differentiated papillary transitional carcinoma, which arose in a pre-existing pyelocaliceal cyst in a 53-year-old man.
      
In 28 patients with transitional carcinoma of the urinary tract, all treated with chemotherapy, serial measurements of serum tissue polypeptide antigen (TPA) were performed and correlated to clinical evaluations of response.

Chromosomes of 41 bladder carcinomas were studied. The results showed that with the increase of histopathological grading of transitional cell carcinoma and decrease of cell differentiation, both the number and structure of chromosome, had markedly changed. The presence of four types of abnormal chromosome and some double minutes (DMS) may be of some significance in bladder carcinoma, and it is demonstrated that the chromosomal abnormalities and histopathological grading may have certain correlation in bladder...

作者应用染色体技术对41例膀胱癌染色体进行检查。结果表明,随着膀胱移行细胞癌病理分级的增高,癌细胞分化程度的降低,无论染色体数目抑或结构都有明显的变异;四种异常染色体的出现和双微体(DMS)的存在,提示它们在膀胱癌演化中有一定的意义;染色体改变与病理组织学分级间的关系也更一步得到肯定。

Benign and malignant tumor of breast and transitional cell carcinoma of bladder and squamous cell carcinoma of esophagus were quantitatively determined with Ag-NOR technique, and nucleolus of benign and malignant tumor were observed by electron microscope. The results showed that: Ag-NOR dots are different in benign and malignant tumors, and in same malignant tumors of different differentiation degree, malignant tumor differs from benign tumor in the numbers, shape, location and fibrillar centers of their nucleolus....

Benign and malignant tumor of breast and transitional cell carcinoma of bladder and squamous cell carcinoma of esophagus were quantitatively determined with Ag-NOR technique, and nucleolus of benign and malignant tumor were observed by electron microscope. The results showed that: Ag-NOR dots are different in benign and malignant tumors, and in same malignant tumors of different differentiation degree, malignant tumor differs from benign tumor in the numbers, shape, location and fibrillar centers of their nucleolus. Ag-NOR technique is an effective method in neoplastic diagnosis and grade.

本文应用Ag-NOR技术对乳腺良、恶性病变及膀胱移行细胞癌和食道鳞癌进行了定量测定,并对良、恶性肿瘤的核仁进行了电镜观察。结果显示,Ag-NORs颗粒在良、恶性肿瘤及同一恶性肿瘤不同分化程度之间均有显著差异;恶性肿瘤核仁的数目、形态、位置及纤维中心与良性肿瘤均不同。Ag-NOR技术在肿瘤鉴别和分级中具有实际意义。

The nuclear DNA content was determined in 5 cases of grade Ⅱ or Ⅲ dysplasia of the mucosal epithelium,5 cases of papilloma and 45 cases of transtional-cell carcinoma(15 cases each of grade I,Ⅱand Ⅲ respectively)of the urinary bladder and that of 5 cases of normal epithelium was also determined to serve as the control.It was found that the DNA pattern was mainly diploid in normal and dysplastic epithelium and triploid in papilloma, Some cells of the dysplastic epithelium and papilloma showed the DNA pattern...

The nuclear DNA content was determined in 5 cases of grade Ⅱ or Ⅲ dysplasia of the mucosal epithelium,5 cases of papilloma and 45 cases of transtional-cell carcinoma(15 cases each of grade I,Ⅱand Ⅲ respectively)of the urinary bladder and that of 5 cases of normal epithelium was also determined to serve as the control.It was found that the DNA pattern was mainly diploid in normal and dysplastic epithelium and triploid in papilloma, Some cells of the dysplastic epithelium and papilloma showed the DNA pattern in supertetraploid and S phase cells.The DNA content of l papilloma was similar to that of grade I transitional-cells carcinoma. The DNA pattern of aneuploid and S phase cells were increased along with the increasing of the grade of transitional-cells carcinoma. The value of DNA content was significantly different among grade I,Ⅱand Ⅲ transitional-cell carcinoma and was significantly higher in transitional-cell carcinoma than in dysplasia and papilloma( P<0.01).The rate of recurrence and mortality became higher along with the increasing of the grade of the carcinoma and of its DNA content It is believed that the determination of the DNA content of the bladder lesions is of significance for the prognosis of the lesions.

对膀胱粘膜良、恶性病变进行了核DNA含量研究,其中不典型增生(Ⅱ、Ⅲ级),乳头状瘤各5例,移行细胞癌45例(I、Ⅱ、Ⅲ级各15例),正常膀胱粘膜5例。结果显示:正常粘膜,不典型增生主要为2C细胞,乳头状瘤以3C为主,且部分不典型增生和乳头状瘤核DNA含量与移行细胞癌Ⅰ级相近。提示不典型增生和乳头状瘤中部分病例有恶变可能。移行细胞癌随分级升高而DNA含量递增,非倍体、S期细胞增多,各级间以及与不典型增生和乳头状瘤间相差非常显著(p<0.0l)。随访结果显示随着分级升高DNA含量增加而复发率、死亡率上升,故DNA含量检测有助于临床判断预后。
