Abstract
Large cell neuroendocrine carcinoma of the lung (LCNEC) is a high-grade, poorly differentiated tumor that typically does not express somatostatin receptors. Thus, it does not benefit from treatment with somatostatin analogs and peptide receptor radionuclide therapy (PRRT). The current study objective was to demonstrate that treatment with PRRT may be a valid option in neuroendocrine carcinomas with high expression of somatostatin receptors. This is a case report of a 58-year-old man who was diagnosed with LCNEC and received chemotherapy treatment with little benefit. Extensive hepatic and bone metastasis was detected on 111In-pentetreotide scintigraphy following high uptake of the radionuclide by the tumors. The patient benefitted from neuroendocrine treatment initially and from lutetium Lu 177 dotatate subsequently. A significant clinical and radiological response was observed, along with an improvement in quality of life. The use of PRRT is a valid alternative to chemotherapy in patients with LCNEC involving the expression of somatostin receptors.
期刊介绍:
Annals of Nuclear Medicine is an official journal of the Japanese Society of Nuclear Medicine. It develops the appropriate application of radioactive substances and stable nuclides in the field of medicine.
The journal promotes the exchange of ideas and information and research in nuclear medicine and includes the medical application of radionuclides and related subjects. It presents original articles, short communications, reviews and letters to the editor.
