Skipping or delaying a dose of Temodar? I have a Glioblastoma stage 4, discovered 10 months ago Dr. operated 1 week later. Did standard 33 day radiation treatment with temodar for 45. am currently 49, on the 5/28 day plan, month 7 of 12. I have a once in a lifetime opportunity to work with a ministry school in Manila, Philippines for 4-5 weeks. What would be the ramifications of skipping a dose or delaying it for a week or two.
