In most cases, if I understand your question correctly, most of the side effects will be list on the " package insert" of the drug. And it will give you some ideas of what symptoms that you will encounter. You can look it up via Internet.Package insert is the official statement from the drug company about the specific drug it manufactured.
But if you are talking about symptoms predictability of the disease state of CCA,it really depends on an individual basis.(ie: jaundice is not for everyone until the bile flow is impeded;itching is relate to the accumulation of the bile salt under your skin,the more bile accumulated, the more and frequent you will be itching. ) I am a patient for three years and I did not have any of the above symptoms. But I do experience fatigue during my capecitabine adjuvant chemotherapy which is stated in the Xeloda " package insert".
