Abstract: Superficial bladder tumors are the most prevalent form of bladder cancers and transurethral resection is the primary surgical modality for those tumors. However, nearly 65% of patients will have tumor recurrence in five years while about 15% will have progression to muscle invasion. Thus, the primary therapeutic aim is to prevent multiple recurrences and progression to a more advanced, invasive disease. We here report an 87-year-old white male patient with invasive bladder cancer who received an unconventional oral regimen of D-fraction, the bioactive extract of Maitake mushroom (Grifola frondosa), following endoscopic transurethral resection of bladder tumor. Despite a high risk for disease recurrence, follow-up yet indicated no clinical evidence of progression of residual disease or recurrence of invasive cancer. It has been nearly two years but the patient remains remarkably well and appears to be in remission. To our knowledge, this is the first and only case report of possible disease remission in a bladder cancer patient after the two-year follow-up of D-fraction regimen, so that further studies with long terms are required for drawing a relevant conclusion. Nevertheless, it is conceivable that D-fraction is a natural agent that may have clinical implications in patients with superficial bladder tumors.
