Metastatic neuroendocrine carcinoma of right adrenal gland successfully treated with laparoscopic adrenalectomy after multimodal therapy

Introduction: We report a case of laparoscopic adrenalectomy in a salvage setting after multiple chemotherapies for neuroendocrine carcinoma. Case presentation: A 49-year-old man was diagnosed with unknown primary carcinoma with single brain metastasis, and right supraclavicular and mediastinal lymph node metastases. After stereotactic radiotherapy of the brain metastasis and systemic chemotherapy, lymphadanectomy was performed. The pathologic diagnosis was neuroendocrine carcinoma. At 11 months after surgery, computed tomography revealed right adrenal metastasis. Local radiotherapy initially resulted in complete remission. However, adrenal recurrence was noted 10 months later. Laparoscopic adrenalectomy was performed with curative intent. The patient is currently alive without recurrence at 20 months after the operation. Conclusion: Adrenalectomy can become a treatment option if other metastases are well-controlled with systemic therapy. Surgical elimination of oligometastases can offer long-term disease control in selected patients as part of a multimodal approach.
