　　I had colon cancer 3 years ago and had my sigmoid colon removed surgically. One year ago, liver metastasis occurred, with 7 or 8 large and small metastases. Professor Xu, can I use combined immunotherapy?

　　Xu Kecheng:

　　If you haven't had chemotherapy, you should have chemotherapy first. I'll introduce you to a 73-year-old man who also had sigmoid colon cancer with liver metastasis. In March 2010, my nephew came to me and said that his boss's father had colon cancer and had undergone surgery, but multiple liver metastases were found during the operation. He received chemotherapy, but the old man couldn't stand the side effects of chemotherapy. After 3 cycles of treatment, he resolutely refused to continue chemotherapy. At that time, he was weak, vomited every day, and couldn't walk by himself. My nephew hoped that the treatment would be effective, but the old man wouldn't "suffer too much". He could only be given combined immunotherapy. Two weeks later, the old man could eat and walk freely. Six months later, CT follow-up showed that the original liver metastasis had disappeared. If he hadn’t had a sudden heart attack six years later, the old man might have enjoyed a happy life for a longer time.
