  Purpose

RATIONALE: Specialized radiation therapy, such as proton beam radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue in patients with retroperitoneal sarcoma. PURPOSE: This phase I trial is studying the side effects and and best dose of proton beam radiation therapy in treating patients with retroperitoneal sarcoma.

Primary Outcome Measures:
  • Feasibility [ Designated as safety issue: No ]
  • Acute toxicity as assessed by NCI CTC Version 3.0 [ Time Frame: Within 60 days of completion of radiotherapy ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Late toxicity as assessed by the RTOG/EORTC late morbidity scoring system [ Time Frame: After 60 days of therapy ] [ Designated as safety issue: Yes ]
  • Clinical efficacy (local recurrence-free survival, distant metastasis-free survival, and overall survival [ Designated as safety issue: No ]

Estimated Enrollment: 54
Study Start Date: November 2009
Study Completion Date: November 2012
Primary Completion Date: November 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I
Patients undergo proton beam radiotherapy 5 days a week for 6 (preoperative patients) or 8 (post-operative patients) weeks in the absence of disease progression or unacceptable toxicity.
Radiation: Proton Beam Radiation Therapy

Detailed Description:

Detailed DescriptionPRIMARY OBJECTIVES:

I. To determine the feasibility and toxicity of proton radiotherapy for retroperitoneal sarcomas.

II. To determine the maximum safe proton radiotherapy dose for retroperitoneal sarcomas.

III. To determine the maximally tolerated dose of proton radiotherapy for patients with potentially resectable retroperitoneal sarcoma. (Pre-operative cohort) IV. To assess acute side effects from irradiation using proton beam therapy and dose/volume constraints that are derived from conventional radiotherapy. (Postoperative cohort)

SECONDARY OBJECTIVES:

I. To assess the clinical effectiveness of proton radiotherapy for retroperitoneal sarcoma.

II. To determine the long-term toxicity of proton radiotherapy to the abdomen and pelvis region.

III. To monitor for effects of proton treatment on tumor and normal tissues using radiographic imaging (both cohorts) or ex-vivo analysis of tissue samples (preoperative cohort only).

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patients with a histologic diagnosis of sarcoma in the peritoneum/retroperitoneum/pelvis are eligible for this study
  • Patients must have either radiographic(pre-operative) or pathologic (post-operative) evidence of disease limited the peritoneum/retroperitoneum/pelvis without evidence of peritoneal sarcomatosis
  • For pre-operative cases, the patient must be considered operable/resectable as judged by the attending surgeon (this is determined by an extensive radiographic and medical evaluation that includes but is not limited to: CT Chest and Abdomen with contrast, MRI/CT Brain and Medical/Cardiac Clearance)
  • Patients should have an EGOC status of 0-2
  • Patients must sign a document that indicates that they are aware of the investigative nature of the treatment of this protocol, and the potential benefits and risks (patients unwilling or unable to sign informed consent are excluded from the study)
  • Women of child-bearing potential as long as she agrees to use a recognized method of birth control (e.g. oral contraceptive, IUD, condoms or other barrier methods etc.); hysterectomy or menopause must be clinically documented

Exclusion Criteria:

  • Prior or simultaneous malignancies within the past two years (other than cutaneous squamous or basal cell carcinoma, melanoma in situ or thyroid carcinoma)
  • Pregnant women, women planning to become pregnant and women that are nursing
  • Patients who experience surgical complications that prevent radiation from starting for 5 months or more, unless there is evidence of gross residual disease
