Neoadjuvant Accelerated Short Course Radiation Therapy With Proton Beam and Capecitabine for Resectable Pancreatic Cancer

A standard treatment for pancreatic cancer is radiation therapy plus chemotherapy after surgery. Radiation therapy and chemotherapy are commonly given for up to six weeks. Previous research has suggested that giving the radiation and chemotherapy for a shorter amount of time (accelerated schedule) before surgery may be better tolerated. In this research study, different schedules of proton radiation therapy will be used. Each schedule will give about the same total dose of radiation. However, the total dose will be spread out over different time periods and different numbers of sessions. The purpose is to find the shortest schedule of radiation therapy that can be given without unacceptable side effects. Proton beam radiation is being used because of its unique ability to deposit its energy directly in the tumor, resulting in less radiation to normal tissue. A new type of PET scan is also being studied to see if it can help predict the response to pre-surgery treatment.

About this study

  • Not everyone who participates in this research study will receive the same schedule of radiation therapy. The schedule of radiation therapy will depend on the number of participants enrolled on the study and how well they have tolerated their radiation schedule. All patients will receive proton beam therapy.
  • Here are the proposed schedules of radiation therapy. If at any point too many subjects experience too many unacceptable side effects, no subject will be enrolled to the next level. Dose Level 1: 10 radiation sessions given Monday-Friday for two weeks. Dose Level 2: 5 radiation sessions given Monday, Wednesday and Friday in Week 1 and Tuesday and Thursday in Week 2. Dose Level 3: 5 radiation sessions given Monday, Tuesday, Thursday and Friday in Week 1 and Monday in Week 2. Dose Level 4: 5 Radiation sessions given Monday through Friday in Week 1.
  • In Dose Levels 2, 3 and 4, there are fewer radiation sessions, but the radiation dose given at each session is slightly higher than the dose given in each of the 10 sessions of Dose Level 1.
  • Capecitabine will be given orally (pill form) starting on the first day of radiation therapy and will be taken for the two weeks that the participant receives radiation therapy.
  • On days 1, 8 and 15 of each study cycle, the participant will be seen at the clinic for: physical examination, questions about side effects; and routine blood tests.
  • After the last day of study treatment there will be up to a six-week rest period before surgery is performed.
  • About three to six weeks after the participant has finished study treatment, the following procedures will be done: CT or MRI, physical examination; questions about side effects and blood tests.

Treatment and study plan

Proton Beam Radiation

Procedure

Given over different schedules and duration

Capecitabine

Drug

Given orally starting on day one of radiation therapy for 2 weeks

Primary outcomes

  1. Number of Participants With Dose Limiting Toxicities in the 5 Radiation Sessions in One Week Arm

    Time frame: 3 Weeks

    The number of participants that experienced a dose limiting toxicity in the arm where radiation was administered over 5 consecutive for a total dose of 25 Gray Equivalents (GyE) (Group 4). Participants were monitored for potential Dose Limiting Toxicities (DLT) for three weeks after the start of radiation. DLTs included:

    • Any grade 3 non-hematologic or hematologic toxicity requiring a greater than 7 day interruption in therapy (excluding alopecia and nausea/vomiting not controlled by optimal supportive care or
    • Any grade 4 non-hematologic toxicity or
    • Any grade 4 neutropenia or thrombocytopenia as defined by Common Terminology Criteria for Adverse Events (CTCAE v3.0)

  2. Number of Participants With Grade 3 or Greater Toxicity in Phase II

    Time frame: 30 days after the end of treatment, up to approximately 6 months total

    Adverse events were assessed using Common Terminology Criteria for Adverse Events (CTCAE 3). The regimen was considered to be tolerated if less than 20% of participants experienced a grade 3 or greater toxicity.

Secondary outcomes

  1. Number of Participants With a Pathological Complete Response

    Time frame: at the time of surgery (28-42 days after start of treatment)

    All patients that received surgery underwent a full pathological review of their pancreaticoduodenectomy specimen according to the American Joint Committee on Cancer (AJCC) Staging Classification, 6th. Initial gross evaluation and identification of resection margins was performed jointly by the surgeon and the pathologist. Pathological complete response will be defined as the absence of any viable tumor cells within the pathologic specimen.

  2. Median Progression Free Survival

    Time frame: from the start of treatment until death or progression, median duration of 10.4 months

    The median amount of time from the start of treatment until death or disease progression, whichever occurs first.

    Progressive Disease (PD): A 20% or greater increase in the sum of Longest Diameter (LD) of all target lesions, taking as reference the smallest sum LD recorded since baseline.

  3. Number of Participants With Surgical Morbidity

    Time frame: 30 days post surgery (surgery was 28-42 days after the start of treatment)

    Number of participants with pancreatic or any other anastomotic leakage within 30 days of surgery

  4. 30-Day Post Operative Mortality

    Time frame: 30 days after the time of surgery (Surgery is 28-42 days after start of treatment)

    The number of participants that died within 30 days of undergoing a pancreaticoduodenectomy.

  5. Number of Participants With Treatment Related Serious Adverse Events

    Time frame: From the start of treatment until 30 days after the end of treatment, up to approximately 5 months

    The number of participants that had treatment related serious adverse events. Adverse events were assessed using Common Terminology Criteria for Adverse Events (CTCAE 3). Adverse events were considered to be serious adverse events if they were grade 3 or greater and were considered to be possibly, probably, or definitely related to treatment.
