Pirarubicin Pasting for Radiotherapy of Inoperable Colorectal Cancers

Abstract

Three cases of inoperable primary or recurrent colorectal cancer were subjected to pirarubicin pasting during radiotherapy. The tumor masses dissolved or greatly regressed, and the patients resumed their activity. The technique is simple, safe, and effective, and it may also be applicable to other approachable cancers, with or without the concurrent radiotherapy. Other anticancer chemotherapeutics, which do not harm normal tissue, may also be used.
