The tolerability, toxicity and therapeutic efficacy of recombinant interferon alpha-2a (rIFN alpha-2a), administered by intralesional injection, were evaluated in 15 patients with papillary superficial transitional cell carcinoma of the bladder, rIFN alpha-2a was delivered endoscopically in a single weekly dose of 3 x 10(6) IU for 4 weeks (total 12 x 10(6) IU).

Abstract
The tolerability, toxicity and therapeutic efficacy of recombinant interferon alpha-2a (rIFN alpha-2a), administered by intralesional injection, were evaluated in 15 patients with papillary superficial transitional cell carcinoma of the bladder, rIFN alpha-2a was delivered endoscopically in a single weekly dose of 3 x 10(6) IU for 4 weeks (total 12 x 10(6) IU). Transurethral resection of residual tumours was then performed. The response to treatment was assessed according to ultrasonographic, endoscopic and pathological findings. One patient achieved complete remission, 6 partial remission, 6 minor remission and 2 stabilisation of disease. All patients completed the course of treatment. A mild, transient, flu-like syndrome was documented after every injection. Immunological findings suggest that the antitumour effects of rIFN alpha 2a are not mediated through the immune system.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
