Omega-3 Polyunsaturated Fatty Acids and Non-Muscle Invasive Bladder Cancer

Overview

The investigators hypothesize that omega-3 polyunsaturated fatty acids (n-3 PUFAs) might have a role in prevention of the recurrence of non-muscle invasive bladder cancer (NMIBC). The patients who are suffering from high-risk NMIBC will be randomly allocated into two groups: The first group (n-3 PUFAs group): 55 patients will receive omega-3 plus twice daily for one year after transurethral resection of bladder tumor (TURBT). The second group (Control group): 55 patients will receive placebo twice daily for one year after TURBT. All patients will receive intravesical Bacillus Calmette-Guérin (BCG) immunotherapy and they will be followed up for two years. The chemopreventive effect of n-3 PUFAs on the recurrence of NMIBC after TURBT will be studied via magnetic resonance imaging (MRI), inpatient cystoscopy, histopathological examination and molecular studies of the resected bladder tissues.

The patients who are suffering from high-risk NMIBC will be randomly allocated into two groups: The first group (n-3 PUFAs group): 55 patients will receive omega-3 plus (1200 mg) orally, twice a day for at least 12 months. The treatment will start after transurethral resection of bladder tumor (TURBT), as soon as the histopathology will be obtained. The treatment will be discontinued if recurrence develops, unacceptable or serious adverse events occur or according to the patients' request. The second group (Control group): 55 patients will receive placebo twice daily for one year after TURBT. Patients and care providers will be blinded to the medication given. All patients will receive intravesical Bacillus Calmette-Guérin (BCG) immunotherapy and they will be followed up for two years. The chemopreventive effect of n-3 PUFAs on the recurrence of NMIBC after TURBT will be studied via magnetic resonance imaging (MRI), inpatient cystoscopy, histopathological examination and molecular studies of the resected bladder tissues.
