Аннотация
BACKGROUND: Gastrointestinal stromal tumors (GISTs) are usually refractory to standard chemotherapeutic agents. We successfully treated a patient with a tyrosine kinase inhibitor (STI571) for GIST with peritoneal dissemination and liver metastases.
METHODS: In a 32-year-old man presenting with abdominal pain from diffuse peritonitis, a GIST and associated perforated small intestine were resected. Multiple liver metastases were present. After therapies with microwave coagulation, ethanol injection, and local and systemic antineoplastic drugs (fluorouracil, cisplatin, tegafur-uracil, and tegafur) failed, investigational treatment with a tyrosine kinase inhibitor was initiated (STI571, 300 mg, p.o. daily).
RESULTS: Anorexia and abdominal fullness resolved within a few days. At 24 days after initiation, positron emission tomography showed a remarkable decrease in the abdominal uptake of [18F] fluorodeoxyglucose. Adverse effects of STI571, including mild alopecia and anemia, were minimal.
CONCLUSIONS: The tyrosine kinase inhibitor STI571 may be effective against GISTs.
