Clinical outcomes for 61 cases of hypopharyngeal cancer with synchronous esophageal cancer.

abstract：:In this review, we would like to introduce a unique approach for the estimation of radioadaptation. Recently, we proposed a new methodology for evaluating the repair efficiency of DNA double-strand breaks (DSB) using a model system. The model system can trace the fate of a single DSB, which is introduced within intron...
