Gastrointestinal Stromal Tumors: A Review

Area of Science:

• Oncology
• Molecular Biology
• Translational Research

Background:

• Gastrointestinal stromal tumors (GISTs) arise from aberrant molecular pathways.
• GISTs are traditionally resistant to chemotherapy.

Purpose of the Study:

• To review the molecular biology and clinical presentation of GIST.
• To discuss the use of tyrosine kinase inhibitors (TKIs) in various stages of GIST.
• To highlight newer therapeutic advances in GIST management.

Main Methods:

• Review of molecular pathways in GIST development.
• Analysis of clinical presentation and management strategies.
• Discussion of adjuvant, neoadjuvant, and metastatic treatment with TKIs.

Main Results:

• Targeted molecular therapy has shown dramatic success in GIST treatment.
• TKIs have redefined the management of GIST, improving outcomes.
• Advances in GIST therapy continue to emerge.

Conclusions:

• Understanding GIST molecular pathways has led to effective targeted therapies.
• Tyrosine kinase inhibitors are crucial in managing GIST across different disease stages.
• The field of GIST therapeutics is rapidly evolving with new advancements.
