Brief Summary:
The aim of this research project is to assess the feasibility and safety of carbon-ion radiotherapy (CIRT) for the treatment of in Chinese localized prostate cancer

Condition or disease Intervention/treatment Phase
Prostate Carcinoma Device: carbon-ion radiotherapy Not Applicable

Detailed Description:
The purpose of this study is to determine the maximal tolerated dose (MTD) of CIRT in the treatment of localized prostate cancer and to evaluate the efficacy of such treatment at the MTD. Participants will be treated with CIRT with escalating dose regimens to evaluate the maximal tolerated dose (MTD) in terms of acute and subacute toxicity observed during and within 6 months after the completion of CIRT. Once the MTD for localized prostate cancer is determined, the MTD will be used as the recommended dose to patients fulfilling the inclusion criteria in the Phase II part of the trial.

Arm Intervention/treatment
Experimental: carbon-ion radiotherapy
Four dose levels [59.2 GyE(Gray equivalent)/16Fx, 60.8 GyE/16Fx, 62.4 GyE/16Fx, 64.0 GyE/16Fx] are planned within the Phase I part. After the recommended dose (RD), i.e., MTD, is determined or if the treatments to 64 GyE/16Fx are safely delivered, the recommended dose (or 64 GyE/16Fx) will be the prescribed dose in the Phase II part of the study.
Device: carbon-ion radiotherapy

Primary Outcome Measures :
  1. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 [ Time Frame: From the date of CIRT to 6 months after the completion of CIRT, up to 6 months ]

Secondary Outcome Measures :
  1. Overall survival of all patients [ Time Frame: From the diagnosis of localized prostate, a median of 2 years ]
  2. biochemical failure-free survival,bFFS [ Time Frame: From the completion of CIRT, a median of 2 years ]
  3. Progression-free survival of all patients [ Time Frame: From the completion of CIRT, a median of 2 years ]
