GLUT1: A Novel Tool Reflecting Proliferative Activity of Lung Neuroendocrine Tumors

Lung neuroendocrine tumor (LNT) represents approximately 20% of all lung cancers. The classification of LNT relies upon morphology. Recently, in the World Health Organization (WHO) classification, Ki-67 rate has been proposed for classi fication. It is, however, known that Ki-67 count has a poor interlaboratory reproducibly. For that reason, our team has looked for a new biomarker.

GLUT1 protein a facilitative glucose transporter protein which has ubiquitous expression in mammalian. GLUT1 is overexpressed in many human cancers. But, no study has evaluated the GLUT1 staining as an aid diagnosis in LNT.

The team have assessed the GLUT1 immunohistochemical staining in 36 LNT and to assess its diagnostic value.

Study Population

Between 2009 and 2014, 36 consecutive patients underwent a surgical resection or biopsy of pulmonary neuroendocrine tumor at University Hospital of Amiens: 5 cases of atypical carcinoid tumor; 13 cases of typical carcinoid tumor; 8 cases of small cell neuroendocrine carcinoma; and 10 cases of large cell neuroendocrine carcinoma. Clinical data were obtained from retrospective review of medical records: population characteristics (age, gender) and tumor size

Description

Inclusion Criteria:

  • Patients with neuroendocrine tumors
