Phase I Study of Low Kilovoltage Intraoperative Radiation for Patients With Resectable Pancreatic Adenocarcinoma

Currently, for patients with pancreatic cancer the standard treatment is surgery followed by
chemotherapy and/or radiation therapy. An investigational approach is to perform the surgery
and treat the area of the tumor with intraoperative radiotherapy in one procedure.
Intraoperative radiation delivers low energy x-rays to a targeted area during the time of
tumor removal.

The purpose of this study is to learn about both the good and bad effects of adding
intraoperative radiation therapy. Another goal is to determine and compare the quality of
life before and after the procedure. We will also monitor the effect of the therapy on the
cancer lesion and any complications that may result.

The purpose of this study is to determine safety of low kilovoltage radiotherapy delivery of
a focused dose of radiation to the areas at high risk for locoregional recurrence following
pancreaticoduodenectomy. This surgery is currently the only potentially curative approach
for patients with pancreatic cancer. Unfortunately, following surgery alone >50% of patients
will have a local recurrence of disease [5]. Local control will become increasingly
important as chemotherapy regimens continue to improve the distant metastases-free survival.
Intraoperative radiation therapy allows direct access to the tumor bed and areas of concern
while allowing displacement and shielding of normal tissue and organs at risk of radiation

Study Objectives The primary objective is to determine the maximum tolerated dose (MTD) for
low kilovoltage (kV) intraoperative radiotherapy (IORT)

The secondary objectives are:

To develop acute and chronic toxicity profiles for this treatment modality

To determine the feasibility of including low-kV IORT in the treatment of pancreatic cancer

To evaluate the following physics and delivery parameters: treatment prescription dose,
depth of treatment, applicator type, and treatment time.

To measure patient's quality of life (QOL) before and after treatment, including change in
pain level and fatigue level.

To describe the disease specific outcomes of local regional control, progression
free-survival, distant metastasis free-survival, disease free-survival and overall survival
associated with low-kV IORT following pancreaticoduodenectomy.

Inclusion Criteria:

- Pathologically confirmed pancreatic adenocarcinoma.

- Age ≥ 18 years.

- Performance status ECOG 0-1.

- Patient must have resectable disease. In order to be resectable the following
criteria must be met:

- Absence of distant metastases.

- Clear fat planes around the celiac axis, hepatic artery, and superior mesenteric
artery .

- Absence of direct involvement of inferior vena cava or aorta.

- Stage I and stage II disease per AJCC 7th edition.

- Complete history and physical examination including weight and ECOG performance
status within 31 days of entry.

- Laboratory data obtained ≤ 14 days prior to registration on study, with adequate bone
marrow and organ function defined as follows:

Laboratory Test Result Leukocytes ≥3000/mm3 Absolute Neutrophil Count (ANC) ≥1500/mm3
Platelets ≥100,000/mm3 Total Bilirubin ≤1.4 mg/dL AST(SGOT),ALT(SPGT) ≤2.5 x institutional
upper limit of normal Serum creatinine ≤1.0 mg/dL INR ≤1.5 BUN < 20 mg/dL Albumin ≥3.5

- Negative serum pregnancy test for females of childbearing potential within 14 days of
study registration. Should a female participant become pregnant or suspect she is
pregnant while participating in this study, she should inform her treating physician

- A female of child-bearing potential is any woman (regardless of sexual orientation,
having undergone tubal ligation, or remaining celibate by choice) who meets the
following criteria:

- Has not undergone a hysterectomy or bilateral oophorectomy; or

- Has not been naturally postmenopausal for at least 12 consecutive months.

- Abdominal CT scan with contrast prior to performance of surgery. If patient is
allergic to contrast an abdominal MRI may substitute. Other imaging may be added or
substituted as deemed appropriate by the treatment team (surgeon, radiation
oncologist, medical oncologist).

- Ability to understand and the willingness to sign a written informed consent.

- Signed study specific informed consent.

- Patients with prior history of malignancy are permitted to register in the study as
long as they are not actively taking cytotoxic or biologic medication for treatment
of the prior malignancy. Patient must be disease-free from any malignancy for at
least the previous 6 months and must have no history of brain metastases.

- Consultation, agreement, and documentation by a radiation oncologist that the patient
is suitable to receive radiotherapy per this protocol.

- Consultation, agreement, and documentation by surgeon that the patient is a suitable
surgical candidate.

- Consultation, agreement, and documentation by an anesthesiologist that patient is
suitable to receive general anesthesia.

Exclusion Criteria:

- Defined treatment area which cannot be adequately covered by the radiation field as
defined by the radiation oncology treatment team.

- Patients who have received neoadjuvant chemotherapy are ineligible.

- Patients with Stage III-Stage IV disease.

- Patients who have been on an immunosuppressive agent (excluding corticosteroids)
within 4 weeks of the proposed operation.

- Patients receiving any other investigational agents.

- Current pregnancy or currently nursing.

- History of brain metastases.

- Severe, active comorbidity defined as follows

- Unstable angina and/or congestive heart failure requiring hospitalization within the
last 6 months. [23]

- Myocardial infarction within 3 months of study registration [23].

- Acute bacterial or fungal infection requiring intravenous antibiotics at the time of

- Chronic Obstructive Pulmonary Disease or other respiratory illness hospitalization or
precluding study therapy at time of registration [23].

- Uncontrolled diabetes which in the opinion of any of the patient's physicians
requires an immediate change in management. A patient may be considered eligible if
the patient's physician managing the diabetes deems the appropriate changes in
management have resulted in adequate control. [23].

- BMI >30.

- Patient with active diagnosis of a bleeding disorder. [23]

- Patients enrolled in another interventional clinical trial.
