Malignant neoplasms of the duodenum are rare, but can be caused by a variety of factors, including genetic predisposition, environmental exposure, smoking, and certain diseases such as chronic pancreatitis and Crohn’s disease.
Diagnosis is made through a combination of endoscopic examination, imaging tests such as CT scan or MRI, and biopsy.
Differential diagnosis includes benign tumors, inflammatory conditions, and other malignancies in the digestive tract.
Treatment for malignant neoplasms of the duodenum typically involves surgery, chemotherapy, and/or radiation therapy.
Prognosis depends on the size and location of the tumor, as well as the patient’s overall health. Generally, patients with small tumors and no metastasis have a better prognosis than those with larger tumors or metastatic disease.
