Brief Summary:

This is a prospective Phase II study.The purpose of this study is to monitor the side effects and treatment outcomes of delivering higher doses of radiation therapy to the tumour, while limiting the dose of radiation to the normal tissues. This will be done using a 5 day treatment schedule.

The characteristics of patients whose disease remains confined to limited areas in the long term, compared with those who do not will also be described.


Condition or disease Intervention/treatment Phase
Solid Tumors With Oligometastatic Spread Radiation: Radiation: 50Gy in 5 fr (max) to 25 Gy in 5 fr (min). Dose adapted to deliver the highest dose level while respecting normal tissue tolerance Phase 2

Detailed Description:
Endpoints are to describe: the proportion of patients with local control for the index site at 1 year; the number of index lesion(s) with local control at 1 year; acute and late AEs related to SBRT; time to local progression for the index site; time to distant disease progression; symptom and QoL profile; median survival.

Arm Intervention/treatment
Experimental: Stereotactic Body Radiation Therapy
All patients will be treated with SBRT 1-2 weeks after radiotherapy planning scans. Therapy will be given once daily, over 5 consecutive working days according to standard practice.
 Radiation: Radiation: 50Gy in 5 fr (max) to 25 Gy in 5 fr (min). Dose adapted to deliver the highest dose level while respecting normal tissue tolerance
All patients will be treated with SBRT 1-2 weeks after radiotherapy planning scans. Therapy will be given once daily, over 5 consecutive working days according to standard practice.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Proportion of patients with lack of progressive disease for the index site at 1 year [ Time Frame: 10 years ]
    CT will be used for evaluation of the status of the local disease at the index site.


Secondary Outcome Measures :
  1. Number of index lesion(s) with lack of progressive disease at 1 year. [ Time Frame: 10 years ]
    The Modified Response Evaluation Criteria for solid Tumors (RECIST) will be used. By measuring the longest diameter (LD) of the lesions, response of individual lesions and overall response will be documented.

  2. Acute toxicity within 90 days of first fraction of radiotherapy [ Time Frame: 10 years ]
    Acute toxicity will be graded according to the Common Toxicity Criteria, v4.0

  3. Time to local progression for the index site(s) [ Time Frame: 10 years ]
  4. Time to distant disease progression (beyond known sites of oligometastases at time of study entry) [ Time Frame: 10 years ]
  5. Late toxicity occuring beyond 90 days related to SBRT. [ Time Frame: 10 year ]
    Late toxicity will be graded according to the Radiation Therapy Oncology Group/ European Organization for Research and Treatment of Cancer score.

  6. Describe symptom profile [ Time Frame: 10 Years ]
  7. Examine radiotherapy parameters (outlined in Appendix J) for local control of index site(s) and toxicities [ Time Frame: 10 years ]

Other Outcome Measures:
  1. Explore pre-treatment prognostic factors derived from clinical data and correlative studies for disease free interval [ Time Frame: 10 years ]
  2. Explore pre-treatment prognostic factors derived from clinical data and correlative studies for local control of index site(s) at 1 year [ Time Frame: 10 years ]
