Selected instances: Metastatic colon cancer when in multiple areas and non resectable reequires chemotherapy. Radiation can not be used systemically and is delivered to a single site. If mass is large, in preparation for resection, radiation has been employed. New monoclonals being developed thatt have alpha emmitters and can be delivered to colon Ca as a form of internal radiation.

Not often: Radiotherapy can be useful in certain select cases where the Cancer is localized to one or two spots only. This means 1 patient in 5 may be suitable candidate. But you need to seek consultation with a radiation oncologist before you can get a clear cut answer for your circumstances.

What do you mean?: my first question is what do you mean chemotherapy fail. what kind of symptoms the patient has to indicate failure. and to answer your question, if surgery is no longer an option to control the metastases. then it is wait and see.
