Comparing Carbon Ion Therapy, Surgery, and Proton Therapy for Management of Pelvic Sarcomas Involving the Bone
Prospective Comparative Effectiveness Trial of Carbon Ion Therapy, Surgery, and Proton Therapy for the Management of Pelvic Sarcomas (Soft Tissue/Bone) Involving the Bone
Study Overview
Status
Intervention / Treatment
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.

Sampling Method
Study Population
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

Any of the following:
- Pregnant women
- Nursing women
- Men or women of childbearing potential who are unwilling to employ adequate contraception

Observational (questionnaires, medical record review)
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.

What is the study measuring?
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.
|
Up to 5 years after completion of treatment
|
Progression-free survival - distant 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 distant control as well as progression-free survival for each arm and stratified by arm.
|
Up to 5 years after completion of treatment
|
Overall 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 overall survival for each arm and stratified by arm.
|
Up to 5 years after completion of treatment
|
Overall 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 overall survival for each arm and stratified by arm.
|
Up to 5 years after completion of treatment
|
Overall survival - distant 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 distant control as well as overall survival for each arm and stratified by arm.
|

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Secondary and exploratory analyses on toxicity data
Time Frame: Up to 5 years after completion of treatment
|
Secondary and exploratory analyses on data will be conducted utilizing standard logistic regression analysis for acute (< 6 months) and late (> 6 months) toxicity.
|
Up to 5 years after completion of treatment
|
Secondary and exploratory analyses on dose volume histogram (DVH) data
Time Frame: Up to 5 years after completion of treatment
|
Secondary and exploratory analyses on data will be conducted utilizing standard logistic regression analysis for acute (< 6 months) and late (> 6 months) toxicity.
|
Up to 5 years after completion of treatment
|
Dose volume histogram
Time Frame: Up to 5 years after completion of treatment
|
Secondary and exploratory analyses on toxicity and DVH data will be conducted utilizing standard logistic regression analysis for acute (< 6 months) and late (> 6 months) toxicity.
Receiver-operator curves and area-under-the curve will be computed separately for each DVH metric to determine the effect on toxicity, QOL, local control and survival.
|
Up to 5 years after completion of treatment
