2002 JUN 26 - (NewsRx.com & NewsRx.net) -- An original procedure to perform a vaccination of cancer patients with a composition prepared with their own blood has been developed by PharmaBlood, a company with headquarters in Florida.

The vaccine includes a pretreatment of the patient in order to reach high blood levels of tumor-released specific molecules or tumor antigens. A sample of patient's blood is further submitted to laboratory procedures to improve its antigenicity prior to being reinjected to the patient. In addition, the patient's immune system is conditioned for an empowered immune response. The procedure includes an internal vaccination performed by high production and release of tumor antigens inside the patient, followed by an external vaccination, performed by reinjection of a tumor antigens composition obtained from patient's blood. As with other described autologous tumor vaccinations, this is a personalized treatment because each patient is vaccinated with the antigens of its own tumor.

The new procedure is innovative by two characteristics: 1) pretreating patients in order that their tumors become more antigenic for the hosts is an absolutely new approach to ...
