I was on a clinical trial but it did not work. I have a rare type of mutation KRAS Q61. I have had 4 liver biopsy since the beginning of the year. My last one he sent 9 samples in house for studies. Also he has sent them for genetic testing and different mutations. I have a meeting with him on Wednesday I found another place that does genetic testing so I am going to see what he says about this place. Thanks again for the information.
