II Conclusion Surgical Resection, Including En Block Resection Of Locally Advanced Tumors, Remains The Only Curative Treatment. Overall Survival And Disease Free Survival Were Significantly Affected By Size Of The Tumor, Grade Of The Tumor And The Resection Status. Key Wards Gastrointestinal Stromal Tumor- GIST – Sarcoma – CDII7 –CD34 – Therapy – Surgery.
