through study completion, an average of 1 year
Study Arms (1)
Arm 1
EXPERIMENTALDose-escalation phase I clinical study. In the initial dose levels, 'dose-escalation' refers to an increase in the radiotherapy dose delivered using carbon ion radiotherapy along with a corresponding decrease in the dose delivered using photons.
Interventions
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.
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.

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.
Eligibility Criteria
You may qualify if:
- Signed the informed consent form;
- Age ≥ 18;
- Capable of following the protocol
- Cytologically or histologically proven diagnosis of adenocarcinoma of the pancreas;
- Unresectable adenocarcinoma of the pancreas by radiographic criteria according to the criteria of the NCCN Guidelines and based on post-chemotherapy imaging or due to medical contraindications to radical resection;
- No evidence of distant metastases based on imaging evaluation;
- Maximum tumor and positive lymph node diameter ≤ 6 cm;
- ECOG Performance Status 0-1;
- Life expectancy ≥ 12 weeks;
- Adequate blood function: absolute neutrophil count (ANC) ≥1.5 x 109/L, platelet count ≥100 x 109/L, and hemoglobin ≥9 g/dL (use of transfusion to achieve said levels or greater is acceptable);
- Adequate liver function: total bilirubin \<1.5 x ULN, and AST and ALT \<2.5 x ULN;
- Adequate kidney function: serum creatinine ≤1.25 x ULN or calculated creatinine clearance rate ≥50mL/min and urine protein \<2+.If the patient's baseline urine protein is at ≥2+, urine samples must be taken for 24 hours to verify that urine protein is ≤1g;
- Laboratory studies within 14 days prior to registration demonstrating that the internationalization standard ratio (INR) ≤1.5 and prothrombin time (PPT) ≤1.5 x ULN.
- Prior receipt of 2-4 cycles of Gemcitabine-based systemic chemotherapy.
You may not qualify if:
- Lack of pathologic confirmation of pancreatic malignancy prior to treatment initiation;
- ECOG Performance Status \>=2;
- Poor liver, kidney and bone marrow function that do not meet the requirements for treatment;
- Persistent grade ≥ 2 toxicity due to previous cancer treatment;
- Patient has previously received abdominal radiation therapy or abdominal radioactive seed implantation;
- Those wearing a cardiac pacemaker or another type of metal prosthetic implant whose normal functions may suffer interference from high energy radiation or that could affect the radiation target area;
- 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.;
- If the doctor determines that the heavy proton or carbon ion dosage radiotherapy will not bring any benefit to the patient;
- Patients suffering from another illness or other factors that could affect the proton or carbon ion therapy;
- Pregnant (verified by serum or urine β-HCG test) or breastfeeding females;
- Drug-abuse or alcohol dependency;
- 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;
- HBV positive patients suffering from replicative stage of hepatitis virus, requiring antiretroviral therapy but cannot due to a concomitant disease;
- Patients with a history of mental illness that may prevent their completion of treatment;
- Patients with serious complications that could affect the course of treatment, including:
