Abstract EN
Bladder cancer is the second most common urological cancer with an estimated 53,200 diagnosed cases and 12,100 resultant deaths in the year 2000.
The incidence of bladder cancer has increased over the past two decades due to improved detection rate of the early stages of the disease i.e.
superficial bladder cancer, while the decreasing mortality rate results from a decrease in the incidence of invasive and metastatic form of the disease and improvement in the therapy.
Angiogenesis is a prerequisite for normal growth and development and abnormal angiogenesis is a critical feature of many diseases including cancers.
The molecules that stimulate angiogenesis are called angiogenic factors and are released by tumour cells or leukocytes within the tumour.
This submitted work has been performed to fulfill the following objectives: 1- Determination of the angiogenic stimulators, Platelet derived growth factor (PDGF) and nitric oxide (NO) in sera as well as basic fibroblast growth factor (bFGF), hyaluronic acid (HA) and hyauronidase (HAase) in urine of patients with bladder cancer as well as reference healthy persons and patients with benign bladder lesions for comparison.
2- Matching of the assayed measures to be correlated with clinicopathological criteria of pat ients.
The current study included 60 patients divided into two groups: I) Group 1: included 30 patients who were already diagnosed as bladder cancer by cystoscopy and biopsy, and further subdivided into 2 subgroups according to the histopathological picture of their cancer tissues into: A) Squamous cell carcinoma (76.7%) included 22 patients B) Transitional cell carcinoma (23.3%) included 8patients II) Group II: included 30patients with benign bladder lesions subjected to: 1) Thorough clinical examination.
2) Urine analysis 3) Complete blood picture.
4) Cystoscopy.
5) Biopsy and histopathological examination of the tissue sample.
The study also included 14 reference healthy subjects.
The work has concluded that serum levels of PDGF were significantly higher J(p<0.0001) in patients with bladder cancer compared with both of benign —bladder diseases and the -healthy subjects.
Mean while, serum levels of PDGF were also significantly higher in-patients with benign bladder diseases compared to healthy persons.
Measured bFGF in the urine of patients with bladder cancer was significantly higher with respect to those with benign lesions as well as the reference healthy cases.(P<0.0001).
Urinary HA of bladder cancer patients was also significantly higher than those with benign bladder lesion or healthy persons (P <0.0001).
Urinary HA ase activity was found to be significantly higher in the patients wy bladder cancer compared to those with benign bladder lesions and the healthy pe)~ (P<0.0001).
The serum concentrations of nitric oxide were significantly higher in-patients bladder cancer compared to those with benign bladder diseases and the healthy gr0u i (P <0.0001).
Conclusively, this work obviates that measured angiogenic factors (PDGF and bFGpj have a domain role in development of bladder cancer.
Hence, angiogenic inhibitors are as beneficial components as adjuvant therapy with surgery, chemotherapy anj radiotherapy.
