Abstract

Despite its histological resemblance to colorectal adenocarcinoma, there is little information about the molecular events involved in the pathogenesis of intestinal‑type sinonasal adenocarcinoma (ITAC). The present study investigated the possible role and clinical value of microRNA (miR)‑let‑7a, a head and neck squamous cell carcinoma‑related miR, in a well‑characterized and homogeneous cohort of patients with ethmoidal ITAC associated with occupational exposure, treated by primary surgery. miR‑let‑7a expression levels were analyzed in 23 pairs of ethmoidal ITAC and adjacent normal formalin‑fixed paraffin‑embedded tissues by reverse transcription‑quantitative PCR. The expression was evaluated in tumor and healthy tissues according to: Tumor grade (G) of differentiation and extension, and pTNM stage, and presence/absence of recurrence. Comparisons within and between groups were performed using two‑tailed Student's paired t‑test and one‑way ANOVA with Tukey's post hoc test. P<0.05 was considered to indicate a statistically significant difference. miR‑let‑7a expression in ethmoidal ITAC tissues was significantly lower than that in adjacent normal tissues (P<0.05; mean expression level ± SD, 1.452707±1.4367189 vs. 4.094017±2.7465375). miR expression varied with pT stage. miR‑let‑7a was downregulated (P<0.05) in advanced stages (pT3‑pT4) compared with earlier stages (pT1‑pT2). Furthermore, downregulation of miR‑let‑7a in ITAC was associated with poorly‑differentiated (G3) cancer (P<0.05). No other associations were observed between miR‑let‑7a expression and the other clinicopathological parameters, including disease‑free survival. In conclusion, downregulation of miR‑let‑7a in ITAC was associated with advanced‑stage (pT3 and pT4) and poorly‑differentiated (G3) disease, suggesting that the mutation of this gene, combined with additional genetic events, could serve a role in ITAC pathogenesis.
