PG - 244-7 LID - S1525-7304(13)00257-X [pii] LID - 10.1016/j.cllc.2013.06.012 [doi] AB - BACKGROUND: Small-cell lung cancer in young patients is very rare and has not been adequately described. In addition, malignancies associated with genetic rearrangements of nuclear protein of the testis (NUT) have been reported in young patients. PATIENTS AND METHODS: We reviewed the clinical records of patients younger than 40 years of age who had been diagnosed as having SCLC and had been treated for this condition. We also examined NUT rearrangements using immunohistochemistry (IHC) staining and fluorescence in situ hybridization (FISH) analysis. RESULTS: We evaluated the diagnoses and treatment outcomes of 8 young patients among 747 SCLC patients. Based on further analyses using IHC staining and FISH, NUT rearrangements were found in 2 of these cases. The range of the overall survival period was 3.6 to 49.7 months. The 2 patients with NUT rearrangements survived for less than 12 months. CONCLUSION: NUT rearrangements were identified in 2 patients who had been previously diagnosed as having SCLC. Further attention regarding the diagnosis of SCLC in young patients is needed. CI - Copyright (c) 2014 Elsevier Inc. All rights reserved.
