- Karnofsky Performance Status of ≥ 70 within 28 days prior to study entry
- No systemic chemotherapy given prior to pre-operative radiotherapy
- Able to provide written, informed consent
- Women of childbearing potential and men who are sexually active must practice adequate contraception.
Exclusion Criteria:
- Tumor pathology of GIST, Ewing's sarcoma or rhabdomyosarcoma
- Metastatic disease to the retroperitoneum from a primary sarcoma not originating from the retroperitoneum
- Systemic chemotherapy given prior to pre-operative radiotherapy.
- Intent on giving chemotherapy ≤ 12 months from the completion of radiotherapy
- Inability to undergo a 4D-CT simulation
- KPS < 70
- Unable to provide informed consent
- Pregnant women

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
To determine the extent of inter-fractional and intra-fractional movement of the GTV during radiotherapy treatments.
Tidsramme: 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.
|
3 years
|
|
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.
Tidsramme: 10 years
|
To describe the effect of radiotherapy to the patient by measuring the acute and long-term side-effects of radiation therapy.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Describe variations in the volume and shape of the GTV over the course of the treatment and need for adaptive therapy.
Tidsramme: 3 years
|
To measure and better define the response of the tumor to radiotherapy during treatments.
|
3 years
|
|
Correlate the pattern of local recurrence with the dose of radiation delivered accounting for motions and volume changes of target structures.
Tidsramme: 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.
