Brief summary

The main purpose of this study is to assess the short term and the long term side effects of proton beam radiation for pediatric bone and non-rhabdomyosarcoma soft tissue sarcomas.

Detailed description

* Participants will receive radiation treatments once per day, 5 days a week for a total of 4 to 6 weeks, depending on how much total dose the tumor requires. The radiation doctor will see the participant once each week to monitor and record any side effects they may have from radiation treatment. * A special device will be made for each participant to help them hold still during the treatment. This may either be a mask or foam cradle, depending on the area to be treated.

Interventions

Once per day, 5 days a week for a total of 4 to 6 weeks.

Inclusion criteria

* Biopsy proven Non-Rhabdomyosarcoma Soft Tissue Sarcoma (NRSTS) or bone sarcoma * Less than or equal to 30 years of age * Patients must have been treated with a standardly accepted chemotherapy regimen if chemotherapy is indicated * Patients must be willing to receive follow-up care for a minimum of five years after treatment at MGH and annual visits unless it is too difficult to return to MGH for follow-up care. In that event, the patient or guardian must be willing to have their outside medical information released in order to track the results of treatment * They or their legal guardian must give their informed consent * Timing of radiation may be according to concurrent protocol

Exclusion criteria

* Co-morbidities that would make the use of radiation too toxic to deliver safely, such as serious local injury of collagen vascular disease * Patients who are pregnant * Previous treatment with radiation therapy * Concurrent adriamycin or gemcitabine chemotherapy is planned, unless on a concurrent protocol

MeasureTime frameDescription
Cumulative Incidence (Estimated Percentage of Participants) Who Developed Toxicities Following Radiation Treatment5 years from the completion of radiation treatmentCumulative incidence (percent of participants and 95% confidence intervals) who experienced a grade 3, 4, or 5 late toxicity. Late complications are defined as the delayed effects attributable to radiation which occur \> 90 days following completion of radiation.
Local Control5 years from the start of radiation treatmentRates of local control using proton radiotherapy. Local control is the lack of tumor recurrence in and or near the area where the primary tumor occurred.

Primary

Cumulative Incidence (Estimated Percentage of Participants) Who Developed Toxicities Following Radiation Treatment

Cumulative incidence (percent of participants and 95% confidence intervals) who experienced a grade 3, 4, or 5 late toxicity. Late complications are defined as the delayed effects attributable to radiation which occur \> 90 days following completion of radiation.

Time frame: 5 years from the completion of radiation treatment

Local Control

Rates of local control using proton radiotherapy. Local control is the lack of tumor recurrence in and or near the area where the primary tumor occurred.

Dosimetric Comparison

Comparison of Dose distribution to tumor and surrounding normal structures using Dose-Volume Histograms (DVH) generated from the proton plan used to treat the patient and the photon plan generated for comparison purposes.

Time frame: 5 years

Population: Data were not collected and this outcome was not analyzed. DVH's were not generated for these patients. Data will not be collected in the future. The decision not to generate photon/proton contours DVH's was at the discretion of the dosimetrist/treating physician.
