Gastrointestinal stromal tumors (GIST) are diagnosed by C-Kit expression. While diagnosis is straightforward, prognosis is difficult. Targeted therapy with STI 571 shows promising results for C-Kit expressing tumors.

Area of Science:

  • Oncology
  • Molecular Pharmacology

Context:

  • Gastrointestinal stromal tumors (GIST) are a distinct anatomical concept.
  • GIST are characterized by the expression of the protooncogene C-Kit.

Purpose:

  • To elucidate the diagnostic and prognostic challenges of GIST.
  • To highlight the therapeutic implications of C-Kit expression in GIST.

Summary:

  • Diagnosis of GIST is generally straightforward.
  • Prognosis evaluation for GIST is often challenging.
  • Surgical resection is the primary treatment modality for GIST.
  • Tumors expressing C-Kit show a notable clinical response to the tyrosine kinase inhibitor STI 571.

Impact:

  • The response of C-Kit expressing GIST to STI 571 represents a significant advancement in molecular pharmacology.
