Numerical, dimensional or mixed progression disease to imatinib as prognostic factor in patients with metastatic GIST.
2017
11040 Background: The majority of GIST patients with advanced disease initially achieves disease control from imatinib treatment. Approximately 10% of patients progresses within 6 months of starting therapy (primary resistance) and also 50-60% of the responding patients develops progression disease within two years (secondary resistance). Progression disease (PD) can be numerical, dimensional or mixed. The known prognostic factors of risk stratification in local disease are tumor size, mitotic activity and anatomic site. In this retrospective analysis we explore several clinical factors affecting survival in metastatic setting. Methods: The population included in this large database of 128…
Second-line treatment in exon 11-mutated GIST patients: Imatinib dose escalation or sunitinib? Retrospective analysis of a multi-institutional experi…

10515 Background: Data from metastatic GIST patients harbouring exon 11 mutation who received a second line treatment with sunitinib or imatinib dose escalation were retrospectively analysed to compare survival. Methods: 123 exon 11 mutated advanced GIST patients were included. All patients progressed on imatinib 400 mg/die and received, on discretion of physician, a second line treatment with either imatinib (800 mg/die) or sunitinib (50 mg/die 4 weeks on/2 weeks of or 37.5 mg/day continuous daily dose). The type of exon 11 mutation was recorded (deletion versus others) and correlated with survival and response according to RECIST or CHOI criteria Results: 79 patients (64%) received a seco…
