Abstract

T‑cell immunoglobulin and mucin domain‑­containing-3 (TIM‑3) performs a critical function in immune tolerance by suppressing the activation and proliferation of T cells. TIM‑3 serves an important role in tumor progression in a number of carcinomas, including non‑small cell lung cancer, hepatitis B virus‑associated hepatocellular carcinoma, Langerhans cell sarcoma, head and neck cancer and follicular B cell non‑Hodgkin lymphoma. The aim of the present study was to evaluate the possible association of TIM‑3 with the prognosis of osteosarcoma. TIM‑3 expression was assessed by immunohistochemical analysis in osteosarcoma tissues. The association between TIM‑3 expression and prognosis was examined. To assess the association between TIM‑3 expression levels and clinicopathological features, a Fisher's exact test was used. TIM‑3 overexpression was indicated to be associated with surgical treatment and survival. Kaplan‑Meier analysis indicated that TIM‑3 is an independent predictor of overall survival, and its overexpression was indicated to be associated with poor prognosis in patients with osteosarcoma. Additionally, reverse transcription‑quantitative polymerase chain reaction and western blot analysis were carried out to evaluate TIM‑3 expression levels in fresh tumor tissue samples, adjacent‑tissue samples, osteosarcoma cell lines, and in an osteoblastic cell line. TIM‑3 was indicated to be overexpressed in fresh osteosarcoma tissue samples and in osteosarcoma cell lines. In conclusion, TIM‑3 overexpression is associated with poor survival among patients with osteosarcoma and may be a possible therapeutic target in these types of tumors.
