7. Where it is not possible to achieve the predetermined safety dose limit with the dose equivalent limit of the organ at risk such as the liver or digestive tract, etc.;

8. If the doctor determines that the heavy proton or carbon ion dosage radiotherapy will not bring any benefit to the patient;

9. Patients suffering from another illness or other factors that could affect the proton or carbon ion therapy;

10. Pregnant (verified by serum or urine ß-HCG test) or breastfeeding females;

11. Drug-abuse or alcohol dependency;

12. HIV positive, including those that have received antiretroviral therapy; replicative stage of chronic Hepatitis B virus; active stage of Hepatitis C; and active stage of syphilis;

13. HBV positive patients suffering from replicative stage of hepatitis virus, requiring antiretroviral therapy but cannot due to a concomitant disease;

14. Patients with a history of mental illness that may prevent their completion of treatment;

15. Patients with serious complications that could affect the course of treatment, including:

• Unstable angina, congestive heart failure, or myocardial infarction requiring hospital admittance over the last 6 months;

• Acute or systemic bacterial infection;

• Chronic exacerbated obstructive pulmonary disease or other respiratory system disease requiring inpatient treatment;

• Impaired liver function or impaired kidney function;

• Patients suffering from immunosuppression;

16. Patients with contraindications to receiving radiotherapy, such as a serious connective tissue disease (eg: scleroderma)

17. Patients that are unable to understand the objective of the treatment/cannot sign the informed consent form;

Intervention

Radiation:
• Carbon Ion
Study subjects will receive carbon ion radiotherapy (CIRT), with daily fraction sizes of 3 GyE. The total CIRT dose will increase with each dose level. Subjects in dose level 1 and 2 will receive photon radiotherapy as well.

Drug:
• Gemcitabine + Cisplatin
Combined chemotherapy regimen before/after radiotherapy: gemcitabine-based chemotherapy regimen. All patients will have received 2-4 cycles of gemcitabine-based chemotherapy prior to study registration, with post-chemotherapy imaging demonstrating locally-advanced disease without evidence of distant metastatic disease spread. Patients who received chemotherapy regimens other than those listed above may be considered for study enrollment at the discretion of the lead investigators, provided that all other eligibility criteria are satisfied. Gemcitabine-based chemotherapy will be continued starting 3-5 weeks after completion of radiotherapy until disease progression, intolerability, or the patient's decline of chemotherapy.
• Gemcitabine + Capecitabine
Combined chemotherapy regimen before/after radiotherapy: gemcitabine-based chemotherapy regimen. All patients will have received 2-4 cycles of gemcitabine-based chemotherapy prior to study registration, with post-chemotherapy imaging demonstrating locally-advanced disease without evidence of distant metastatic disease spread. Patients who received chemotherapy regimens other than those listed above may be considered for study enrollment at the discretion of the lead investigators, provided that all other eligibility criteria are satisfied. Gemcitabine-based chemotherapy will be continued starting 3-5 weeks after completion of radiotherapy until disease progression, intolerability, or the patient's decline of chemotherapy.
• Gemcitabine + Erlotinib
Combined chemotherapy regimen before/after radiotherapy: gemcitabine-based chemotherapy regimen. All patients will have received 2-4 cycles of gemcitabine-based chemotherapy prior to study registration, with post-chemotherapy imaging demonstrating locally-advanced disease without evidence of distant metastatic disease spread. Patients who received chemotherapy regimens other than those listed above may be considered for study enrollment at the discretion of the lead investigators, provided that all other eligibility criteria are satisfied. Gemcitabine-based chemotherapy will be continued starting 3-5 weeks after completion of radiotherapy until disease progression, intolerability, or the patient's decline of chemotherapy.
• Gemcitabine
Combined chemotherapy regimen before/after radiotherapy: gemcitabine-based chemotherapy regimen. All patients will have received 2-4 cycles of gemcitabine-based chemotherapy prior to study registration, with post-chemotherapy imaging demonstrating locally-advanced disease without evidence of distant metastatic disease spread. Patients who received chemotherapy regimens other than those listed above may be considered for study enrollment at the discretion of the lead investigators, provided that all other eligibility criteria are satisfied. Gemcitabine-based chemotherapy will be continued starting 3-5 weeks after completion of radiotherapy until disease progression, intolerability, or the patient's decline of chemotherapy.

Radiation:
• Photon
During this study, the prescribed dose shall be administered according to the dose escalation shown in the table, starting with dose level 1. The carbon ion dose shall be gradually escalated while gradually reducing the dose of photons until eventually administering a full dose of 56 GyE/14 Fx carbon ions (fractional dose of 4 GyE). Dose escalation will be performed in parallel for two patient groups: patients whose pancreatic tumors are greater than 5 mm from the duodenum (Group A) and those whose tumors are within 5 mm of the duodenum (Group B). Enrolled patients will be monitored for 90 days after radiotherapy starts for any acute toxic reaction and to explore the maximum tolerated dose, in addition to being observed for any related long-term toxic reactions in accordance with the protocol.
