Brief summary

The arm of this study is to explore the optimal dose of 12 fractions of carbon ion radiotherapy for prostate cancer in our center.

Detailed description

The radiation dose of 51.6GyE in 12 fractions is currently widely used in Japan, and clinical studies of 51.6GyE/12Fx have also been carried out for SBRT. There are some differences in equipment and carbon ion treatment planning system used between Japan and our center. Therefore, we designed this phase I clinical study to explore the optimal dose of 12 fractions of carbon ion radiotherapy for prostate cancer.

Interventions

dose escalation radiotherapy with five levels of dose from 54GyE/12Fx to 58.8GyE/12Fx
