During the surgery, if it is decided that all of the tumors can be removed, the abdomen will be closed with a plastic tube left in place. Then, the abdominal wash will begin. During the wash, a pump that is connected to the plastic tube pushes the heated doxorubicin into the abdomen and then pulls it out to recirculate the doxorubicin. The heated doxorubicin will be recirculated in and out of the abdomen over 90 minutes while the surgeon gently presses on the abdomen to help the doxorubicin reach all areas in the abdomen. The plastic tube that the heated doxorubicin will be pumped through will stay in place after the surgery to drain the extra fluid. These are the same plastic tubes that would be present even if participant did not agree to take part in this study.
