containing B7 . If you receive cells not containing B7 and you don't have a 
good response after receiving all 6 planned injections, we may try to give you 
the cells containing B7 in the same way as long as you are still in good 
enough condition to continue treatment on this protocol. You will be told 
prior to entering the study whether you would receive the cells with B7 or the 
cells without B7 . 
As long as your tumor is stable or shrinking, you may continue on the therapy 
up to a maximum of 6 treatments. Before, during and after treatment you will 
have x-rays, blood samples taken, and other lab tests performed to monitor 
your therapy. We will ask if we can remove a small area around the site of an 
injection 2 weeks after the first and fourth injections for investigational 
purposes. This will involve minor surgery that is performed with local 
anesthesia. We will also remove for investigational purposes, with your 
permission, any swollen surface lymph nodes or surface tumors at similar 
times. The risks of these biopsies include bleeding, infection, or poor 
healing leading to a chronic open wound or ulcer. However, the chances of 
complications occurring from a local surgical procedure are low. If you refuse 
to have these minor surgeries you may still participate in the study. 
Side Effects 
The extent and severity of side effects cannot be totally predicted. It is 
possible you may develop redness, swelling, or an ulcer at the place where the 
injection has been given. The lymph nodes in your groin or arm may become 
tender and swollen. Other side effects may occur. 
Alternative Treatments 
Your doctors are very willing to discuss the benefits and side effects of 
alternative treatments including the option of treatment of your symptoms only 
with no further cancer therapy. Other investigational protocols with 
chemotherapy, hormones, radiation therapy, or novel anti-cancer agents may be 
available for your disease. Please ask questions you may have and take as 
much time as you need to make your decision. 
Confidentiality 
When results of a study such as this are reported in medical journals or at 
meetings, identification of those taking part is withheld. Medical records of 
patients are maintained in strictest confidence according to current legal 
requirements. In the past, studies such as this one that involved genetic
