Medical Summary - updated July 23 2007

I have stage IV colon cancer, which means that there is a primary tumor in the colon and it has spread via the bloodstream to another place. In my case, at the time of diagnosis, there was a very large tumor on my liver. In addition, there was possible cancerous activity in the local lymph nodes and two small places in the lungs. Neither of these latter two problems were certain (although later proved to be cancer and were removed).

What I've done so far:

(1) To start things off (June 2003), I had almost three rounds of chemo. Each round consists of a 21 day cycle of chemo. Day one, I take intravenous CPT-11 (ironotecan). Days 1-14, I take Xeloda, the oral form of 5-FU, in the morning and in the evening. These three rounds shrunk the liver tumor almost 50% and made the lung spots go away. This was very encouraging, as this chemo is effective in only 50% of colon cancer patients.

(2) The third round was aborted due to colon obstruction at the tumor site. I spent a week in the hospital in Dallas before it opened just enough to get by for a few weeks.

(3) Then I had surgery to remove the primary tumor. Dr. Rogriguez, surgeon at MD Anderson Cancer Center (MDACC) performed the helicolectomy, a removal of the half of the colon containing the tumor. In addition, he removed the surrounding lymph nodes, a few of which turned out to be cancerous. While I was opened up, he also looked around for cancer that had not shown up on the radiology tests. He found no other visible cancer. The removed tumor was analyzed and found to be only 20% viable due to the effectiveness of the chemo.

(4) After recovering from surgery, I began chemo again. One day shy of having completed two more rounds of chemo, I developed clostridium difficile bacteria in my bowels. This was treated during a three-day stay at a local Richardson hopsital.

(5) After complications due to the onset of c-diff bacteria, I was delayed a few weeks. Dr. Hoff decided it was about time to do another round of radiology tests and we received the results on Dec 8. To everyone's surprise the tumor had shrunk remarkably and it was determined the next week by the surgeon, Dr Vauthey, that I was ready for surgical resection. MD Anderson's approach to liver resection for colon cancer is described in the article.

(6) The surgery was performed on Dec 22 and I spent Christmas in the hospital. I had quite a group with me during this time. According to the surgeon, it went "perfectly": the tumor was removed in one piece (all the right lobe and part of the left), there was no need to remove any of the diaphragm, and most importantly, there was no cancer found beyond that which was taken out. Christmas, it seems, came anyway. The recovery is rough, as I had 76% of my liver removed. But I am steadily regaining strength as it regenerates.

(7) Having gone through surgical removal of the liver tumor, more chemo (possibly with a different drug) was necessary for good measure to assure ourselves that all remnants of the cancer are gone. I completed this round in spring of 2004.

(8) At the end of spring, they noticed a small nodule in the pelvic region. They tried to biopsy it via a colonoscopy, and the samples taken were negative for cancer. Three months later, it showed growth, so they did an external biopsy, which proved positive for cancer. They also noticed that this nodule may have been on the original scans back in 2003. I think it was there all along.

(9) They decided to do a different type of chemo, which is now the frontline approach (it wasn't FDA approved when I began all my treatments). This protocol is called FOLFOX with Avastin. After several rounds of this, the nodule shrunk, so they were willing to go after it with surgery.

(10) In February of 2005, I had major surgery to get this nodule taken out. They sucessfully got it, and saw no remaining cancer anywhere in my belly when they were in there. The surgery was miraculous in that the side effects were relatively few, even though many bad side effects were quite possible and even expected - including removal of my bladder or rectum. None of that was necessary!

(11) There was a very small (less than 1mm) margin of non-cancerous tissue around the edge of the the removed blob of tissue. This means a good chance there are still microscopic cancer cells left. So they decided to do 4 rounds of chemo (FOLFOX-Avastin), then radiation, then a final 4 rounds of chemo.

(12) The radiation was completed July 5, 2005. I did the radiation in Houston at MD Anderson.

(13) After radiation, they wanted to do some more chemo for good measure. So I did four rounds of FOLFOX-Avastin, finishing in September 2005.

(14) In October 2005, the CT scans were clear(!)

(15) Jan 2006 I had my first 3-month checkup, which inluded a full torso CT scan. There were a couple of spots that showed up on the scan on my lungs. These had been there before but had disappeared (with chemo?). They were too small to know what they were. Dr Hoff suggested that I return in 8 weeks for another scan of the lungs.

(16) March 23,2006 a couple days after the scan I met with my new oncologist, Dr. Cathy Eng (Dr. Hoff moved back to Brazil, his home country). Unfortunately, the scans showed significant growth of the spots and several others as well. The largest is 11mm, just big enough to biopsy. So we are scheduling a biopsy - probably around April 17.

(17) April 7, 2006. The biopsy was positive for cancer. Details here. I am now taking a four rounds of irinotecan + intravenous 5fu, fourteen days per round. The story behind this protocol decision is here. The hope is to shrink and kill. I'm hoping surgery will become an option to remove the lung mets.

(18) May 22, 2006. Due to low white blood cell count and intestinal pain, probably from the chemo iritating them, my doctor postponed round three of chemo for one week.

(19) Nov 11, 2006. I finished my last round of chemotherapy. All these years of chemo is really beating me down. I requested a consult with a lung surgeon. To my surprise, he told me I was a good candidate for surgery. (details) Lung surgery to remove the mets in my left lung is scheduled for Jan 5, 2006.

(20) Jan 5, 2007. Successful lung surgery, left lung. I had thoracotomy with two wedge resections to take out two mets in my left lung. The surgeon expects to do a similar operation on my right lung in a couple months. You can follow my surgery by looking at blog entries from January 2007.

(21) March 23, 2007. Successful lung surgery, right lung. I had another thoracotomy, this time with four wedge resections to take out mets. Surgery details are in blog entries from March 2007.

(22) April 19, 2007. Met with my surgeon, and my clinical oncologist, Dr. Eng, at MD Anderson. No evidence of disease, no treatment planned. Return July 24 for CT scans. This feels like the first remission, although it actually is the third. The first was tentative where there was something on the CT scan, but the biopsy was negative for cancer, but was done "blindly". The second remission was with the knowledge that there were (likely) lung mets that had shrunk to not be visible on scans. This time - no trouble spots.

All of this is done under the care of a team of doctors at MD Anderson Cancer Center (MDACC) in Houston, TX.
