Hi!
Colon cancer survival rates for people who live in the U.S. (the five-year survival rate - the percentage of patients alive five years after their initial colon cancer diagnosis) are 83% for colon cancer stage 3a.
Chemotherapy can be used for many stages, but usually starting from stage 3.
Chemotherapy given before or after surgery can destroy microscopic areas of cancer and increases the chances of a cure.
A combination of drugs often works better than a single drug in treating colorectal cancer. The most commonly used drugs are:
Fluorouracil (5-FU) combined with leucovorin.
Fluorouracil (5-FU) combined with leucovorin and oxaliplatin.
Capecitabine, sometimes combined with irinotecan or oxaliplatin.
Oxaliplatin, sometimes combined with 5-FU.
Irinotecan, sometimes combined with 5-FU.
In some studies, people who had surgery and then were given the chemotherapy drugs fluorouracil (5-FU) and leucovorin lived longer.
I guess your mother will receive one of the combination of drugs, also, used in U.S.
Best wishes to you and your family!
Please, keep us updated about your mum's health!
Thinking of you!

Is your mother getting leucovorin with her fluorouracil? If you read up on leucovorin, you should see the reason why...to extend the brief time that the fluorouracil is potent.
