So, you'll see my message above, but I wasn't on any new drugs. The trial involved using these two therapies together for the first time.
The pump was good because it delivered chemo directly to my liver. With colon cancer, it is most likely that that is where the cancer will travel to. However, when they used the pump alone, it didn't carry any chemo to the rest of the body.
So, the Irinotecan worked to deliver chemo to the rest of my body.
This worked well for me.
Here is a note from Sloan Kettering about the trial

Here are the findings.
Researchers found that patients receiving HAI lived longer than those receiving systemic chemotherapy, with a median survival of 24 versus 20 months. In addition, patients receiving HAI had better response rates (47 percent versus 24 percent) and longer time to disease progression in the liver (9.8 months versus 7.3 months).
Patients receiving HAI did not experience the usual side effects associated with systemic therapy such as diarrhea, decreased white blood cell counts, and hair loss. However, because patients on the HAI regimen experienced mild toxicity to the liver, their liver function was monitored closely throughout the duration of treatment to prevent the toxicity from becoming more severe.
The research began in 1996, before chemotherapy drugs such as irinotecan and oxaliplatin were available, so both sets of patients received the standard drugs at the time, fluorouracil and leucovorin, and had access to the newer drugs as they became available.
According to Dr. Kemeny, studies are currently underway at MSKCC using HAI therapy in combination with newer drugs, and response rates appear to be even higher. Furthermore, the addition of HAI therapy is also being investigated in patients with primary liver cancer.
Let me know if you have any more questions. I just moved into a new house (I helped design it and everything) and spoke at a dinner about my cancer and had two weddings to go to, all in a months time frame, so I've been a bit swamped and apologize for not answering sooner.
