A Study of Photon and Proton Chemoradiotherapy as Definitive or Neoadjuvant Therapy in Non-Metastatic Pancreatic Cancer


About this study

The purpose of this study is to observe adverse events and effectiveness of hypofractionated concurrent chemoradiotherapy for the treatment of pancreatic cancer.


Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Age ≥ 18 years.
  • Histological confirmation of adenocarcinoma of the pancreas (head, body, or tail of pancreas).
  • Imaging consistent with T1-4, N0-2,  M0 pancreas cancer, including potentially resectable, borderline resectable, or unresectable disease as per NCCN classification. When CT of the chest, abdomen, and pelvis are performed, this must be with contast per pancreas protocol. Imaging with a PET/MRI alone is acceptable on study. If a PET/CT is performed, a separate pancreas protocol CT is required for inclusion.
    • *Note: Imaging must be done prior to initiation of radiotherapy and does not need to be completed at time of enrollment.
  • Must have received neoadjuvant chemotherapy at the discretion of medical oncology.
  • Medical oncology consultation to confirm that patient is an appropriate candidate for concurrent chemotherapy, and surgical oncology consultation for confirmation of resection status.
    • Note: Consultation must be completed prior to initiation of radiotherapy and does not need to be completed at time of enrollment.
  • Patients who have received previous chemotherapy for pancreatic cancer are allowed to participate in this study, unless they experienced a previous allergic reaction to the drugs used in this study.
  • Planned to receive CRT, consisting of PBT or IMRT (45 Gy/15 fractions) with concurrent chemotherapy with 5 FU or Capecitabine.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1 or Karnofsky Performance Status 70-100. 
  • Willing to sign consent onto the Mayo Clinic Radiotherapy Patient Outcomes Registry and Biobanking study, IRB 15-000136*.
    • *Patients do not need to agree to Biobank blood draw. 
  • Able to complete standard of care clinical questionnaire(s) by themselves or with assistance.

Exclusion Criteria:

  • Presence of non-regional nodal involvement or distant metastatic disease (M1).
  • Prior radiotherapy resulting in overlap of radiation treatment fields.
  • History of prior malignancy < 2 years of enrollment, except non-melanotic skin cancer or carcinoma-in-situ of the cervix.
  • Immunocompromised patients and patients known to be HIV positive and not currently receiving antiretroviral therapy. 
    • Note: Patients known to be HIV positive, but without clinical evidence of an immunocompromised state, are eligible for this trial.
  • Receiving any investigational agent concurrent with CRT which would be considered as a treatment for the primary neoplasm.
  • Any of the following because this study involves an agent that has known genotoxic, mutagenic and teratogenic effects:
    • Pregnant women;
    • Nursing women;
    • Men or women of childbearing potential who are unwilling to employ adequate contraception.
  • Co-morbid systemic or psychiatric illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens.        
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
