My dad has has a similar story as your mom's. He was Diagnosed with Stage IV colon cancer in September 2010 with mets to the liver, abdomen and lymph nodes.
His oncologist at MSKCC put him on 12 weeks of FOLFOX + an experimental drug, CT011. After 12 weeks, we found the liver mets grew and he now has less than 50 percent function in his liver.
The oncologist switched from this treatment to FOLFIRI + AVASTIN. After 2 weeks, my dad ended up in the hospital with a blockage in his liver.. they had to put a stent in (his bilirubin levels were 6 (.5-1 is normal!). The following week, the oncologist took him off IRINITECAN because she believed it contributed to the blockage. He is now getting a low does of 5FU, leucovorin + avastin. The doctors are not optimistic and say things are getting worse. I am totally devastated over this.
The one piece of advice I can give you is to find out if your mom has a KRAS mutation in the cancer. It took my oncologist nearly 3 months for the liver biopsy to come back to reveal he had a KRAS mutation. This means the cancer is rare and will NOT respond to most systemic therapies (i.e., FOLFOX, FOLFIRI, etc.). If we had known this, he would have never been on FOLFOX for 12 weeks.
Do you know if your mom's cancer has a KRAS mutation?
I am praying for your mom. And never give up hope. No matter what the doctors say, you have to be strong for your family. And sometimes, chemotherapy is not always the answer. I would definitely look into alternative treatments as well.
I am here if you ever want to talk. I have done a lot of research about this. I will do anything to save my dad.
Prayerfully,
Laura
