Treatment - If you take part in this trial you will be treated for about four weeks. You will receive an injection of Allovectin-7® by needle, directly into your tumor. This will be repeated 14 days later. The injections may be given in a doctor's office. A week later, you will undergo surgery to remove the tumor. Your tumor will be measured before Allovectin-7® treatment and before surgery to see if Allovectin-7® was effective in shrinking it. This will be done by general physical exams and scans (such as X-ray scans). There will also be tests on the removed tumor to see if Allovectin-7® helped to boost the immune system to attack the cancer.
