Brief Summary
• Bladder cancer is the most common malignancy of the urinary tract. It represents the 7th most commonly diagnosed cancer in male population worldwide and drops to the 11th when both genders are considered . According to the American cancer society's estimates of bladder cancer in 2017, the number of the new cases of bladder cancer is 79,030, and the mortality figures reached 16,870 .

Study Arms (4)
Low Grade group
• 50 tumor tissue samples from patients with Low Grade Bladder Cancer undergoing either trans urethral resection of bladder tumor or Radical Cystectomy , The followings markers must be estimated : 1. Autophagy markers: * ( Atg7) level using (quantitative real time polymerase chain reaction). * (LC3A)level using immunohistochemistry . 2. ER-stress marker: (ATF6) level using ELISA(Enzyme Linked Immuno sorbent Assay) 3. Oxidative stress Marker:(MDA)using chemical method 4. Apoptotic marker:(caspase 3) using(quantitative real time polymerase chain reaction) .
High Grade group
• 50 tumor tissue samples from patients with High Grade Bladder Cancer undergoing either trans urethral resection of bladder tumor or Radical Cystectomy, The followings markers must be estimated : 1. Autophagy markers: * ( Atg7) level using (quantitative real time polymerase chain reaction). * (LC3A)level using immunohistochemistry . 2. ER-stress marker: (ATF6) level using ELISA(Enzyme Linked Immuno sorbent Assay) 3. Oxidative stress Marker:(MDA)using chemical method 4. Apoptotic marker:(caspase 3) using (quantitative real time polymerase chain reaction) .
Safety margin group
• 50 normal bladder urothelial tissue samples from the safety margin around the tumor(0.5cm to the tumor), The followings markers must be estimated : 1. Autophagy markers: * ( Atg7) level using (quantitative real time polymerase chain reaction). * (LC3A)level using immunohistochemistry . 2. ER-stress marker: (ATF6) level using ELISA(Enzyme Linked Immuno sorbent Assay) 3. Oxidative stress Marker:(MDA)using chemical method 4. Apoptotic marker:(caspase 3) using (quantitative real time polymerase chain reaction).
Control group
• 50 (age and sex matched )control The followings markers must be estimated : 1. Autophagy markers: * ( Atg7) level using (quantitative real time polymerase chain reaction). * (LC3A)level using immunohistochemistry . 2. ER-stress marker: (ATF6) level using ELISA(Enzyme Linked Immuno sorbent Assay) 3. Oxidative stress Marker:(MDA)using chemical method 4. Apoptotic marker:(caspase 3) using (quantitative real time polymerase chain reaction)..
Eligibility Criteria
patients with confirmed bladder cancer (histopathologically) having LGBC(Low Grade bladder cancer) undergoing either TUR(transurethral resection of Bladder Tumour) or Radical Cystectomy and patients having HGBC(High Grade bladder cancer) undergoing either TUR(transurethral resection of Bladder Tumour) or Radical cystectomy. Healthy controls\[age and gender matched\](with no previous history of gross hematuria, urolithiasis, or active urinary tract infection)
You may qualify if:
- )patients confirmed histopathologically to have bladder cancer. 2) Both sexes. 3) Patients who will accept to participate in the study.
You may not qualify if:
- Patients with past history of Bladder Cancer with previous chemotherapy or any other types of cancer in the last 5 years.
