    Summary
    This summary is machine-generated.

    Early diagnosis and surgical intervention are crucial for primary duodenal tumors. Lymph node status significantly impacts survival, with resection recommended only in select cases to improve outcomes.

    Area of Science:

    • Gastroenterology
    • Surgical Oncology
    • Oncology

    Background:

    • Primary malignant duodenal tumors are rare, presenting diagnostic and therapeutic challenges.
    • Adenocarcinomas and malignant lymphomas represent the main histological types.

    Purpose of the Study:

    • To evaluate diagnostic procedures, surgical resectability, and survival rates for primary malignant duodenal tumors.
    • To determine the impact of lymph node involvement on patient outcomes.

    Main Methods:

    • Retrospective analysis of 14 patients with primary malignant duodenal tumors.
    • Review of preoperative diagnostic methods including imaging, duodenoscopy, and arteriography.
    • Assessment of surgical outcomes (resectability, mortality) and survival rates.

    Main Results:

    • Resectability rate for duodenal carcinoma was 66.7%, with a 14.2% five-year survival rate.
    • Positive lymph node involvement significantly reduced survival time after Whipple resection.
    • Malignant duodenal lymphoma showed a 50% tumor-free rate at two years with combined therapy.

    Conclusions:

    • Early diagnosis is key for curative surgery in duodenal tumors.
    • Positive lymph node status should generally preclude resective surgery due to higher mortality.
    • Combined surgical and chemotherapeutic approaches offer promising results for malignant duodenal lymphoma.
