[|Human|] I need information about the chemo drug 5-FU.  It is not listed on your list of drugs but is listed in treatment for stage IV rectal cancer.  This cancer has metastisized to liver - 5 lesions - and lungs - 2 lesions on 1 lobe; 1 leison on other lobe.  I want to know its side effects.  Chemo starts tomorrow for 5 days a week for 4 or 5 weeks with 5-FU and also leucovorin.  Simultaneously, radiation therapy will take place 5 days a week for 4-5 weeks.
[|AI|]  Hi, I have gone through your query. Since the rectal cancer has spread to liver, only chemotherapy and radiotherapy will be done.5-FU (Fluorouracil) is mixed with leucovorin in order to increase 5-FU activity. Most common side effects of 5-FU includes:DermatitisMyositisDiarrheaMyelosuppression (Bone Marrow Suppression)Do consider positive feedback as a credit to my work. Let me know if you have any further questions. You can contact me on my page http://bit.ly/1dYupT2
