Brief Summary:
This is a cross-sectional cohort study of metastatic GastroIntestinal Stromal Tumor (GIST) patients on imatinib for ≥ 10 years included in EORTC trial 62005-STBSG entitled "Phase 3 randomized, intergroup, international tiral assessing the clinical activity of STI-571 at two dose levels in patients with unresectable or metastatic gastrointestinal stromal tumor (GIST) expressing the KIT receptor tyrosine kinase (CD117) - NCT00685828". With this study, the aim is to identify patient characteristics, tumour characteristics, treatment factors and quality of life outcomes associated with prolonged treatment with imatinib and/or prolonged survival. This observational study will further help to put in place a questionnaire to evaluate patients quality of life with prolonged imatinib treatment, that will then be used in a prospective study.

Study 62005-STBSG patients treated with imatinib > 10 years Other: No intervention
No intervention

Primary Outcome Measures :
  1. Patient characteristics [ Time Frame: At time of registration ]
    Age at time of randomization, gender, medical history and previous treatment(s)

  2. Tumour characteristics [ Time Frame: At time of registration ]
    Stage of the disease, tumor grade, tumor location and molecular features of primary tumor

  3. Duration of imatinib treatment [ Time Frame: At time of registration ]
    Time on imatinib treatment from start untill definitive discontinuation of imatinib treatment

  4. Health releated quality of life [ Time Frame: At time of registration ]

  5. Overall survival [ Time Frame: At time of registration ]
    From time of randomization to the date of death, whatever the cause

Biospecimen Retention:   Samples With DNA
First, existing data on molecular characteristics of included patients will be collected from the treating centers. If more than 40% of the data is not available, archival tumor tissue from patients enrolled in the EORTC 62005-STBSG study will be collected and used to identify molecular characteristics of the tumor that may predict long-term response to imatinib. Archival tumor tissues will be retrieved from the central lab of the study 62005-STBSG (UZ Leuven, Belgium) or from the sites (if applicable).
