Abstract

Although previous studies have demonstrated that Glut‑1 is the predominant glucose transporter, is significantly overexpressed in various types of tumor and is correlated with poor prognosis, the potential function and clinical value of Glut‑1 expression in osteosarcoma remains largely unclear. In particular, the prospective associations between Glut‑1 expression levels and clinicopathological factors remains to be elucidated. In the present study, immunohistochemistry was performed to detect Glut‑1 protein expression in 51 paired osteosarcoma specimens and adjacent non‑cancerous tissues, and reverse transcription‑quantitative polymerase chain reaction analysis was performed to examine Glut‑1 mRNA expression levels in 6 pairs of these tissues. Statistical analyses were conducted to determine the associations between Glut‑1 expression and various clinicopathological parameters. Glut‑1 protein was revealed to be overexpressed in 38 (74.5%) osteosarcoma tissues, but only in 6 (11.8%) adjacent non‑cancerous tissues. Glut‑1 mRNA levels were also upregulated in osteosarcoma tissues compared with adjacent non‑cancerous tissues. While there were no clear statistical relationships between Glut‑1 expression and patient sex, resection, tumor location, size, T stage and adjuvant treatment, Glut‑1 expression levels were significantly associated with age, tumor‑node‑metastasis stage, lymph node metastasis and survival. The median survival time in patients with low Glut‑1 expression levels was longer than in patients with a high expression level. Glut‑1 was significantly overexpressed in osteosarcoma tissues, and Glut‑1 expression was associated with clinicopathological factors which upregulate the invasion and metastasis of osteosarcoma, and may be a potential predictor of survival in patients with osteosarcoma.
