BACKGROUND/OBJECTIVE: Bladder cancer is the commonest type of malignant tumors as a result of schistosomaisis which is a major healthy problem in many subtropical developing countries. The aim of this study is to comparatively elucidate the underlying biochemical tumor markers in schistosomal bladder cancer versus non-schistosomal bladder cancer when compared to normal healthy ones.
This work was performed on tissue specimens from total 25 patients and serum samples from total 30 patients versus ten healthy individuals served as control. The investigated parameters in serum are: xanthine oxidase (XO), fructosamine, lactate dehydrogense (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), total proteins, essential and non- essential amino acids profile, hydroxyproline, total immunoglobulin E (IgE) and tumor necrosis factor alpha (TNF-α). In addition, the current investigation also extended to study some markers in tumor bladder tissues including, pyruvate kinase enzyme (PK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST) and alanine aminotransferase (ALT).
Results showed that biharzial bladder cancer patients recored more significant elevation in serum XO, fructosamine, LDH, AST, ALT, hydroxyproline, IgE and TNF-α than in bladder cancer patients when compared to control ones. While, in tissues there were significant increase in PK, LDH, AST & ALT activities of schistosomal bladder cancer than in bladder cancer as compared to control healthy patients.
It could be concluded that, bilharzial and non-bilharzial bladder cancer showed distinct biochemical profile of tumor development and progression which can be taken into consideration in diagnosis of bladder cancer.
背景/目的:膀胱癌是由于血吸虫病而导致的最常见的恶性肿瘤类型,这是许多亚热带发展中国家的一个主要健康问题。本研究的目的是比较阐明血吸虫性膀胱癌与非血吸虫性膀胱癌与正常健康者相比潜在的生化肿瘤标志物。
本工作在总共 25 名患者的组织标本和总共 30 名患者的血清样本以及 10 名健康个体的血清样本上进行,作为对照。在血清中检测的参数包括黄嘌呤氧化酶 (XO)、糠胺、乳酸脱氢酶 (LDH)、天门冬氨酸氨基转移酶 (AST)、丙氨酸氨基转移酶 (ALT)、总蛋白、必需和非必需氨基酸谱、羟脯氨酸、总免疫球蛋白 E (IgE)和肿瘤坏死因子-α (TNF-α)。此外,本研究还扩展到研究膀胱组织中的一些标志物,包括丙酮酸激酶酶 (PK)、乳酸脱氢酶 (LDH)、天门冬氨酸氨基转移酶 (AST)和丙氨酸氨基转移酶 (ALT)。
结果表明,与对照组相比,血吸虫性膀胱癌患者的血清 XO、糠胺、LDH、AST、ALT、羟脯氨酸、IgE 和 TNF-α显著升高。而在组织中,与对照组相比,血吸虫性膀胱癌患者的 PK、LDH、AST 和 ALT 活性显著增加。
可以得出结论,血吸虫性和非血吸虫性膀胱癌表现出明显不同的肿瘤发展和进展的生化特征,这可以在膀胱癌的诊断中考虑。
