SOFT- Stereotactic Ablative Radiotherapy of Infra-diaphragmatic Soft Tissue Metastases (SOFT)
April 27, 2022 updated by: Mette Felter, Herlev Hospital
SOFT - A Phase 2 Study of Stereotactic Ablative Radiotherapy of Infra-diaphragmatic Soft Tissue Metastases
The SOFT study will evaluate the feasibility and safety of MR-guided stereotactic ablative radiotherapy (SABR) for infra-diaphragmatic soft tissue metastases.

Detailed Description
The investigators wish to evaluate the safety and feasibility of MR-guided stereotactic radiation to patients with infra-diaphragmatic oligometastatic disease including quality of life assessments and patient-reported outcome measures.
Further, the investigators assess clinical response among patients with oligometastatic disease (OMD), defined as up to five metastases in up to three different organs.

Description
Inclusion Criteria:
- Histology or cytology proven non-haematological cancer.
- At least one metastasis should be localized in the infra-diaphragmatic soft tissue.
- Eastern Cooperative Oncology Group (ECOG) scale of performance status ≤ 2.
- ≥ 18 years old.
- Life expectancy > 6 months.
- Target diameter (GTV) ≤ 5 cm.
- Metastatic lesions must be visible, imaging defined targets and suitable for treatment with SABR.
- In case of de novo OMD and oligometastatic recurrence a maximum of 5 targets (including the primary tumour) in a maximum of 3 organ sites are allowed.
- In case of oligoprogressive disease (OPD) * and induced OMD ** only 3 metastases (including the primary tumour) are allowed.
- All metastatic sites are treated or planned for ablative therapy (including surgery). For OPD, only the sites in progression is required to fulfil this criterion.
- A baseline scan within 28 days of inclusion (PET-CT or CT and MR scanning).
- No curative intended treatment option available.
- An ablative strategy should be deemed clinically relevant and it is at the discretion of the treating physician to decide.
- Ability to understand and the willingness to sign a written informed consent document.
- If the target is in the liver, a Child-Pugh Score A is required.
Exclusion Criteria:
- Patient cannot tolerate physical set up required for SABR.
- Active bowel obstruction.
- Uncontrolled intercurrent illness.
- Medical contraindication to undergoing MR-imaging.
- Pregnancy.
- Patients with uncontrolled brain metastases.
- Uncontrolled disease in respect to malignant pleural effusion, ascites, lymphangitic carcinomatosis, pleural carcinomatosis or peritoneal carcinomatosis.
- If the patient has received previous radiotherapy, the combined dose at the radiation site must not exceed the dose constraints.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Cumulative CTCAE grade ≥ 4 SABR related toxicity (TRAE).
Time Frame: Assessed at 1 year.
|
Registration of toxicity will be assessed according to a prespecified selection of organ related adverse events defined by CTCAE version 5.0.
|
Assessed at 1 year.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Freedom from local progression.
Time Frame: Assessed at week 6, 12, 24, 36, and 52.
|
Defined as the time from inclusion to local progression as determined by investigator using RECIST 1.1 criteria.
|
Assessed at week 6, 12, 24, 36, and 52.
|
Progression free survival.
Time Frame: Assessed at week 6, 12, 24, 36, and 52.
|
The time from inclusion until disease progression determined by investigator assessment of objective disease assessment per RECIST 1.1 .
|
Assessed at week 6, 12, 24, 36, and 52.
|
Time to progression (TTP) outside the radiation field.
Time Frame: Assessed at week 6, 12, 24, 36, and 52.
|
Defined as the time from inclusion until progression outside the radiation field determined by a CT, MR, or PET-CT per RECIST 1.1.
Outside the radiation field is defined as outside and not adjacent to the PTV.
|
Assessed at week 6, 12, 24, 36, and 52.
