Expression levels of miR‑338‑3p and TCF4 in thyroid cancer tissue and their relationship to the clinical pathological features and prognosis
To investigate the correlation between the expression levels of microRNA‑338‑3p (miR‑338‑3p) and T cell factor 4 (TCF4) in thyroid cancer (TC) tissue with clinical pathological features and prognosis.
Methods
2
From September 2018 to September 2020
148 TC patients admitted to The First Affiliated Hospital of Hebei North University were involved in this study
their intraoperative resections of TC samples and adjacent tissues were acquired. qRT‑PCR method was applied to detect the expression levels of miR‑338‑3p and TCF4 in tissues. The relationship between the expression levels of miR‑338‑3p and TCF4 in TC tissue and clinical pathological features and prognosis was analyzed. The factors affecting the prognosis of TC patients were analyzed using multivariate Cox regression.
Results
2
The expression levels of miR‑338‑3p in t
he TC samples were lower than those in the adjacent tissues
and the expression level of TCF4 was higher (both
P
<
0.05). The proportions of miR‑338‑3p low expression and TCF4 high expression in TC patients with stage Ⅲ‑Ⅳ
low differentiation
and lymph node metastasis
respectively
were higher than in stage Ⅰ‑Ⅱ
medium to high differentiation
and no lymph node metastasis
respectively (all
P
<
0.05). The 3‑year survival rate (45.95%) of patients with low expression of miR‑338‑3p in TC tissue was lower than that of patients with high expression of miR‑338‑3p (74.32%) (

and the 3‑year survival rate (41.89%) of patients with high expression of TCF4 in TC tissue was lower than that of patients with low expression of TCF4 (78.38%) (

TCF4

and lymph node metastasis were related factors that affected the prognosis of TC patients (

Conclusion
2
The expression level of miR‑338‑3p in TC tissue is obviously reduced
while the expression level of TCF4 is obviously increased. They are closely related to the clinical stage and lymph node metastasis in TC patients
and are related factors affecting the prognosis of TC patients.
