Praveen, Radiation and chemo can be combined in many different ways. An individual's treatment plan will have little in common with the next person's plan - they are not comparable. I had a series of daily chemo treatments for several weeks. Then twice daily radiation with concurrent chemo mon-fri, week on, week off, for 12 weeks. Different clinics often have their own approach to combining these therapies. Ask the docs lots of questions and let him/her defend their treatment decisions, but avoid the temptation to compare your brother's treatment plan with others. It sounds like the docs have a rationale for their decisons about your brother's care. Thats what counts. Luck to you and your brother. Be strong. Tom J
