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 .

Outcome Measures

Primary Outcomes (1)

  • autophagy marker

    differences in the level of Atg7(autophagy marker) in Low Grade bladder cancer and High Grade bladder cancer groups in comparison with safety margin and healthy control group.

    baseline

Secondary Outcomes (1)

  • stress markers

    baseline

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)..
