Comparing Carbon Ion Therapy, Surgery, and Proton Therapy for Management of Pelvic Sarcomas Involving the Bone

September 18, 2023 updated by: Mayo Clinic

Prospective Comparative Effectiveness Trial of Carbon Ion Therapy, Surgery, and Proton Therapy for the Management of Pelvic Sarcomas (Soft Tissue/Bone) Involving the Bone

This study compares carbon ion therapy, surgery, and proton therapy to determine if one has better disease control and fewer side effects. There are three types of radiation treatment used for pelvic bone sarcomas: surgery with or without photon/proton therapy, proton therapy alone, and carbon ion therapy alone. The purpose of this study is to compare quality of life among patients treated for pelvic bone sarcomas across the world, and to determine if carbon ion therapy improves quality of life compared to surgery and disease control compared with proton therapy.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. Demonstrate whether carbon ion therapy provides improved patient reported health related quality of life (PRO-HRQOL) outcomes and less significant toxicities compared with surgery.

II. Demonstrate whether carbon ion therapy provides improved local control versus proton therapy.

OUTLINE:

Patients complete quality of life questionnaires over 20 minutes at baseline (before any therapy), 2-4 and 5-9 months after completion of therapy, and then annually for up to 5 years. Patients' medical records are also reviewed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

15 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with newly diagnosed, histologic confirmation of pelvic chordoma, chondrosarcoma, osteosarcoma, Ewing sarcoma with bone involvement, rhabdomyosarcoma (RMS) with bone involvement or non-RMS soft tissue sarcoma with bone involvement treated with curative intent carbon ion radiation therapy (CIRT) at one of the carbon ion facilities in Europe or Asia or deemed appropriate to undergo definitive treatment with surgery or radiation therapy at Mayo Clinic (Minnesota, Florida, Arizona)

Description

Inclusion Criteria:

  • Males and females >= 15 years of age
  • Newly diagnosed, histologic confirmation of pelvic chordoma, chondrosarcoma, osteosarcoma, Ewing sarcoma with bone involvement, rhabdomyosarcoma (RMS) with bone involvement or non-RMS soft tissue sarcoma with bone involvement
  • No evidence of distant sarcoma metastases as determined by clinical examination and any form of imaging
  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) =< 2
  • Patients capable of childbearing must agree to use adequate contraception
  • Ability to complete questionnaire(s) by themselves or with assistance
  • Ability to provide written informed consent
  • Chemotherapy per institutional guidelines is allowed

Exclusion Criteria:

  • Patients receiving palliative treatment
  • Recurrent disease
  • Males and females < 15 years of age
  • Previous radiation therapy to the site of the sarcoma or area surrounding it such that it would be partially or completely encompassed by the radiation volume needed to treat the current sarcoma. In other words, treatment on this study would require re-irradiation of tissues
  • Patients with distant sarcoma metastases
  • Benign pelvic bone histologies
  • Any of the following:

    • Pregnant women
    • Nursing women
    • Men or women of childbearing potential who are unwilling to employ adequate contraception

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Average difference in change of functional quality of life (QOL)
Time Frame: Baseline (pre-treatment) to 1 year after completion of treatment
Will be compared between patients who received carbon ion radiation therapy (CIRT) and surgery utilizing a one-sided test for a two sample t-test for independent means. The Patient Reported Outcomes Measurement Information System (PROMIS)-29 functional score will be calculated and median, mean, and 95% confidence interval will be computed for each arm, with one-sided two-sample t-tests conducted between the surgery +/- radiation therapy (RT) and CIRT arm.
Baseline (pre-treatment) to 1 year after completion of treatment
Proportion of patients experiencing local control
Time Frame: Up to 5 years after completion of treatment
Will be calculated along with 95% confidence intervals with a one-sided test for non-inferiority to be conducted between the PT and CIRT arms.
Up to 5 years after completion of treatment
Progression-free survival - local control
Time Frame: Up to 5 years after completion of treatment
The Kaplan-Meier method with likelihood ratio tests will be used to calculate clinical outcomes including local control as well as progression-free survival for each arm and stratified by arm.
Up to 5 years after completion of treatment
Progression-free survival - regional control
Time Frame: Up to 5 years after completion of treatment
The Kaplan-Meier method with likelihood ratio tests will be used to calculate clinical outcomes including regional control as well as progression-free survival for each arm and stratified by arm.
