Gastrointestinal stromal tumors
Adenoid cystic carcinoma (ACC) of the salivary glands is the second most common type of salivary gland cancer, and is characterized by a poor prognosis and an unclear pathology.
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. While imatinib revolutionized first‑line therapy, resistance and specific mutation profiles necessitate subsequent generations of tyrosine kinase inhibitors (TKIs). Sunitinib, regorafenib, and avapritinib represent second‑line, third‑line, and mutation‑specific therapies, respectively, offering improved precision and disease control. This review summarizes clinical trial evidence, real‑world data, and translational studies evaluating the efficacy, safety, and mechanistic basis of second‑ and third‑generation TKIs in GIST.
ACC is a rare and aggressive salivary gland malignancy with limited effective systemic therapies; understanding its biology is essential for developing new treatments.
