ABSTRACT
BACKGROUND:
Large cell neuroendocrine carcinoma(LCNEC)is a relatively rare disease classified as a subtype of neuroendocrine tumor. LCNEC has clinical and histological similarities to small cell lung cancer, both of which have a similarly poor prognosis. There are also unclear points regarding treatment. CASE 43-years-old, male. He had repeated intermittent fever from 1 month before the consultation. Cough appeared 4 days before the consultation, and the family doctor pointed out an abnormal shadow in the right lung field, and the patient was referred. Blood test showed increased CRP 1.34 mg/dL and mild inflammatory response. Chest CT showed an increased tumor with a major axis of 16 cm in the right thoracic cavity compared to 6 months ago. FDG-PET showed accumulation of SUVmax 11.83 in the same area. A CT-guided needle biopsy was performed, and although tumor cell hyperplasia of like a plasma cells was suspected, but most of them were coagulative necrotic images and could not be diagnosed. After hospitalization, fever continued and the general condition became poor, so surgery was performed for the purpose of diagnostic treatment. Preoperatively, Interventional Radiology was used to embolize the tumor-feeding blood vessels. Intrathoracic tumor resection and partial upper and lower lobe resection were performed under thoracotomy. Postoperative histopathological examination revealed that large round to polyhedron tumor cells proliferated in sheet-like or intercellular binding sparsely, and synaptophysin was positive, which was a diagnosis of large cell neuroendocrine cell carcinoma. The general condition improved promptly after the operation, and the patient was discharged 14 days after the operation without any complications. After discharge, 4 courses of adjuvant chemotherapy (CDDP plus CPT-11)were performed. Six months after the operation, the disseminated nodule recurred in the right thoracic cavity. Chemotherapy(CBDCA plus PTX plus BEV)and radiation therapy were performed and the patient was in remission. It has been 5 years since the operation and has not recurred.SUMMARY:
We report a case of rapidly increasing LCNEC with long-term remission by surgical treatment and chemoradiotherapy, with some review of the literature.
