Outline of Final Research Achievements

We developed a practical method for predicting radiosensitivity to realize individualized radiotherapy according to the biological characteristics of cancer cells.
In uterine cervical cancer and prostate cancer, the correlation between expression proteins involved in repair of DNA double-strand breaks of tumor cells by biopsy specimens and radiotherapy results is analyzed, which is a predictive factor of therapeutic effect.
In uterine cervical cancer, the expression rates of Ku 86 and XRCC 4 were predictors of the radiotherapeutic effect on cervical cancer. In prostate cancer, the expression of Ku70 in prostate cancer cells is a prognostic factor independent of clinical factors, and it has been shown that in addition to the prognostic factors presently used in clinical practice, recurrence after radiation treatment can be predicted with high accuracy.
