Overview
Brief Summary
This study is a clinical trial of prospective, single-arm objective performance criteria. This trial will be conducted in clinical trial sites with a total of 47 subjects enrolled. All of subjects will be treated with radiation therapy using the medical device Varian ProBeam Proton Therapy System (ProBeam), aim to compare the data with objective performance criteria (OPC) to evaluate the effectiveness and safety of ProBeam radiotherapy system for oncology patients, providing a clinical basis for the medical device registration.
Detailed Description
Oncology patients, including tumors of the nervous system, head and neck, chest, abdomen, spine, pelvic cavity, limbs and other tumors. The screening period from informed consent to enrollment is expected to be 4 weeks, while the treatment period is 1 to 8 weeks. The period after the last treatment is divided into short-term follow-up and long-term follow-up, in which short-term follow-up will be 3 months after the end of the last treatment. Total expected participation for each subject from screening to the completion of short-term follow-up is a maximum duration of 12 weeks + 3 months. Long-term follow-up continues after the end of short-term follow-up until the 5th year after the end of the last radiotherapy session.

- •5.The subject or subject's guardian is able to understand the purpose of the study, demonstrate sufficient compliance with the protocol and sign informed consent form
Exclusion Criteria
- •The subject with radiotherapy contraindications, including the known genetic tendencies that increase the sensitivity of normal tissue radiotherapy or the accompanying diseases that lead to hypersensitivity to radiotherapy;

Outcomes
Primary Outcomes
tumor disease control rate reaches the objective performance criteria
Time Frame: 3 months ± 7 days after the last treatment
After treatment, CR, PR, SD is considered disease control; Percentage of subjects who developed disease control 3 months after the end of the last radiotherapy session.
CTCAE level 4 and 5 toxic reaction ratio is acceptable value
Time Frame: the entire clinical trial ( until 3 months after last treatment)
The proportion of subjects with toxic reactions of levels 4 and 5 during the clinical trial period.The researchers record AE that appeared during the clinical trial cycle and grade it according to CTCAE 5.0)
CTCAE level 3 toxic reaction ratio is lower than the acceptable value
Time Frame: started from subject enrollment to 3 months ± 7 days after the last treatment, up to 5 months
The proportion of subjects whose toxicity reaction is level 3 during the clinical trial period. The researchers record AE that appeared during the clinical trial cycle and grade it according to CTCAE 5.0
