I really don't understand exactly what you are looking for, I put this "1/2 body radiation for a dog with Stage IV multi centric Lymphoma" in google and looked under "Scholar."
1/2 body radiation for a dog with Stage IV multicentric Lymphoma - Google Scholar
One study says:
Combination of CCNU and DTIC Chemotherapy for Treatment of Resistant Lymphoma in Dogs - Flory - 2008 - Journal of Veterinary Internal Medicine - Wiley Online Library
Conclusions and Clinical Importance:
A combination of CCNU and DTIC can be an effective option to rescue dogs with resistant lymphoma. Don't know if this is what you have in mind though. Maybe there are other studies that are more what you have in mind?
