Brief Summary
This study with Chair-Based, Gantry-less Proton System (CBGS) (aka P-CURE Proton Beam Therapy System or Fixed Beam Chair-based Delivery System) is composed of 3 arms, as following: ARM1: Patients with locally recurrent, previously irradiated thoracic cancer indicated for re- irradiation. ARM2: Patients with recurrent Head and Neck, Brain and Spinal Cord tumors, indicated for re- irradiation. ARM3: Patients with unresectable pancreatic cancer. The primary objectives of the study for all arms are: 1. to describe the efficacy (local control after 3 month) and acute toxicity for patients treated with a fully-integrated CBGS and (2) to compare treatment plans between the fully-integrated CBGS and Photon therapy defined for each patient, based upon OAR sparing for comparable target coverage.

Outcome Measures
Primary Outcomes (3)
Local Control
The duration of local control will be measured from the start date of protocol radiation until the date of progressive disease. Local control will be determined based on RECIST Criteria Version 1.1.
3 months
Acute Toxicity
Incidence of treatment-related grade 3-5 adverse events, graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0
3 months
Treatment Plan Comparison between Chair Based Proton System and Photon therapy
Analysis and comparison of dose volume histograms (DVHs) and isodoses for each modality
3 months

Study Arms (3)
Patients with locally recurrent, previously irradiated thoracic cancer
EXPERIMENTALProspective study shall evaluate treatment efficacy, toxicity, QOL and plan parity in patients with recurrent thoracic cancer previously irradiated, undergoing proton radiation therapy
Patients with recurrent Head and Neck, Brain and Spinal Cord tumors, indicated for re- irradiation
EXPERIMENTALThe prospective study shall evaluate treatment Efficacy, Toxicity, Quality of Life (QOL), and plan parity in adult patients with recurrent Head and Neck and Brain cancer undergoing proton radiation therapy
Patients with unresectable pancreatic cancer
EXPERIMENTALThis prospective study shall evaluate treatment feasibility utilizing the CBGS for unresectable pancreatic cancer with concurrent chemotherapy
Interventions
Proton beam radiotherapy, first proposed by Robert Wilson at Harvard University in 1946, utilizes an energetic beam of ionized hydrogen nuclei (protons) directed at the tumor volume to effect DNA damage of the targeted cells. Today, there are hundreds of proton treatment centers worldwide and it is considered standard treatment for certain malignancies and/or clinical scenarios
Eligibility Criteria
You may qualify if:
- Pathologically (histologically or cytologically) proven malignancy
- Treatment planning analysis shows advantage to proton over photon treatments
- both malignancies (such as thoracic tumors) as well as metastatic lesions (such as metastatic breast cancer or colorectal cancer to the lungs) are allowed
- Patient must have CT confirmation of the tumor
- Patients must have a life expectancy of \> 6 months
- Patients must have measurable disease to be treated with proton radiation (minimum tumor dimension at least 10 mm on CT imaging).
- Patients must be a candidate for definitive radiation dose
- There are no limits on prior therapy. Patients are allowed to have prior chemotherapy and surgery. Patients are allowed to have concurrent chemotherapy with radiation treatment. Patients are allowed to have chemotherapy or surgery after radiation treatment
You may not qualify if:
- Severe, active co-morbidity, defined as follows:
- Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months
- Transmural myocardial infarction within the last 6 months
- Chronic obstructive pulmonary disease exacerbation or other respiratory illness other than the diagnosed lung cancer requiring hospitalization or precluding study therapy within 30 days before registration
- Acquired immune deficiency syndrome (AIDS) based upon current CDC definition (protocol may be significantly immunosuppressive endangering AIDS patients)
- Pregnancy or women of childbearing potential and men who are sexually active and not willing/able to use medically acceptable forms of contraception
- Patients with life expectancy \< 6 months
- Patients that participate in another, active clinical trial carried out concurrently with this protocol
