No Intervention: Follow-up
Data from these patients will be added to retrospectively gathered data from the PMH radiotherapy data bank (approximately 50 patients). The data collected will be analyzed using descriptive statistics.
Radiation: Intensity-Modulated Radiotherapy
Radiotherapy for the treatment of retroperitoneal sarcoma. IMRT will be 50.4 Gy given in 28 fractions.
Other Name: Pre-operative IMRT
Radiation: Daily Cone Beam CT
Images and information from the daily CT will be used for the repositioning of the patient prior to their treatments as per standard procedures.
Other Name: daily cone-beam Computed Tomography (CT)
- To determine the extent of inter-fractional and intra-fractional movement of the GTV during radiotherapy treatments. [ Time Frame: 3 years ]To quantify and describe the movement of the tumor during and between radiotherapy treatments using imagings acquired during the course of radiotherapy planning and treatments.
- To assess the acute and long-term toxicity of pre-operative radiotherapy as a function of the dose given to normal tissues and its impact on patient quality of life. [ Time Frame: 10 years ]To describe the effect of radiotherapy to the patient by measuring the acute and long-term side-effects of radiation therapy.
- Describe variations in the volume and shape of the GTV over the course of the treatment and need for adaptive therapy. [ Time Frame: 3 years ]To measure and better define the response of the tumor to radiotherapy during treatments.
- Correlate the pattern of local recurrence with the dose of radiation delivered accounting for motions and volume changes of target structures. [ Time Frame: 10 years ]To determine whether there is a pattern of local relapse with the actual dose of radiation delivered to the tumor environment when tumor volumetric and positional changes are taken into account.
