Can We Predict of the Response of High Risk Non Muscle Invasive Bladder Cancer Patients to Intravesical Bacillus Calmette-Guerin? The Role of Immunological Markers

January 22, 2021 updated by: Amr Abdel-Lateif El-Sawy, Mansoura University

Intravesical BCG is the mainstay adjuvant management of high risk NMIBC. Adequacy of immune system stimulation is the determinant factor for patient response to BCG. Immunological markers for BCG-response could be helpful for urologists especially in the era of BCG shortage.

Objectives: To assess the predictive performance of different immunological markers on BCG-response in high risk NMIBC BCG-naïve patients.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: High risk NMIBC
Patients with primary or recurrent NMIBC for whom primary TURBT was done and intravesical BCG was administered
Diagnostic test: Urine ELISA for immunological markers (IL-2 and IL-10)
IL-2 and IL-10 levels were measured in the supernatants. Natural human-produced IL-2 and IL-10 concen¬trations were determined in the urine of all patients and controls by solid phase ELISA Quantikine IL-2 Immunoassay and IL-10 Immunoassay, respectively
Diagnostic test: Reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) analysis
blood samples using QIAamp® RNA Blood Mini kit (QIAGEN, USA). 1 μg of total RNA was reverse transcribed with random primers, using High Capacity cDNA Archive Kit (Applied Biosystems, Foster City, CA, USA). RT-qPCR analysis was carried out with SYBER Green PCR Master Mix (Applied Biosystems, Foster City, CA, USA). Primers for TNF-α, CTLA4, T-bet+, GATA3+, FoxP3+ and GABDH as PCR control
