Popis: Purpose: Vaccinia virus is a DNA poxvirus previously used as a vaccine to eradicate smallpox. The virus has a high efficiency of infection, replicates in the cytoplasm without chromosomal integration and can transport a large amount of recombinant DNA without losing infectivity. Therefore, it is an excellent choice as a vector for gene delivery in vivo. Large quantities of vaccinia have been injected into dermal, subcutaneous and peripheral lymph node melanoma metastases without significant side effects, and with efficient infection of the tumor cells and recombinant gene transfection. To determine if vaccinia, when given intravesically, can effectively infect bladder mucosa and tumor with acceptable toxicity, we performed a phase I trial of intravesical vaccinia in patients with muscle invasive transitional cell carcinoma before radical cystectomy.Materials and Methods: After documenting immune competence and demonstration of a major reaction after revaccination, patients received 3 increasing doses of i...
