Successful Salvage Chemotherapy with Streptozocin in a Patient with Mediastinal Atypical Carcinoid Tumor Who Had Relapsed after Various Prior Therapies

Abstract

Pulmonary neuroendocrine tumors are rare, and there have been very few reports regarding optimal chemotherapeutic regimens. Two molecular targeted agents, everolimus and sunitinib, have recently been shown to provide an additional treatment benefit for pulmonary neuroendocrine tumors. However, little information is available regarding the usefulness of streptozocin chemotherapy. Here, we encountered a case of relapsed and refractory mediastinal atypical carcinoid tumor associated with multiple endocrine neoplasia type 1 for various cytotoxic and molecular targeted agents. The patient showed a good response to streptozocin monotherapy. We describe the case and review streptozocin chemotherapy in patients with pulmonary neuroendocrine tumors.
