Summary
This case study highlights a rare malignant gastrointestinal stromal tumor (GIST) successfully treated with surgery. Lifelong follow-up is recommended for GIST patients post-resection due to uncertain tumor behavior.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Pathology
Background:
- Gastrointestinal Stromal Tumors (GIST) are rare mesenchymal neoplasms with variable prognosis.
- Malignant GIST constitutes approximately 2.0% of all malignant gastroenteric tumors.
- Surgical resection is often the primary curative treatment for GIST.
Observation:
- A 69-year-old female presented with asthenia and fever.
- Imaging revealed an exophytic gastric tumor and a 5.5 cm duodenojejunal tumor.
- Surgical resection of both tumors was performed.
Findings:
- Histopathology confirmed spindle cell GIST with a high mitotic rate (>20/10 HPF).
- Immunohistochemistry indicated an uncommitted origin of tumor cells.
- Despite refusing chemotherapy and high malignancy, the patient showed no recurrence or metastasis at 47 months post-surgery.
Implications:
- This case underscores the potential for favorable outcomes following surgical management of malignant GIST.
- The uncertain behavior of GIST, even benign forms, necessitates long-term patient surveillance.
- Lifelong follow-up is proposed for patients treated with potentially curative surgical resection of GIST.
