When adjusted for other factors, the presence of neural invasion (<span class="elsevierStyleItalic">p</span> = 0.013) and KRAS mutations (<span class="elsevierStyleItalic">p</span> = 0.042) increased the mortality rate. In line with clinical predictions, the factors that most determined overall survival in the current model were Akt, the presence of recurrence, and miR-99b-CRC. Independent of other factors, the death rate increased as Akt levels (<span class="elsevierStyleItalic">p</span> = 0.006) and miR-99b expression levels increased in the main tumor (<span class="elsevierStyleItalic">p</span> = 0.045), and as recurrence occurred (<span class="elsevierStyleItalic">p</span> = 0.012).</p><p id="para0048" class="elsevierStylePara elsevierViewall">Although the expression level of miR-99b was the highest in the main tissue, the expression level of miR-135b was the lowest. In addition, although the expression level of miR-99b was decreased in PC and LMV compared with that in primary tumor tissue, the expression level of miR-135b was higher than that in CRC tissue. The reduction in miR-99b expression in PC and LVM tissues compared with that in CRC tissues suggests that it has a protective effect on invasion and metastasis. In contrast, the increased expression of miR-135b in PC and LVM compared to that in the parent tissue suggests that it increases invasion and metastasis. We believe that due to the small sample size in our study, there was no correlation between Akt levels, KRAS mutations, and miR-99b and miR-135b expression levels. Therefore, further experiments should be performed to evaluate the association between the PI3K/Akt/mTOR signaling pathway and changes in miR-99b and miR-135b expression levels.</p><p id="para0049" class="elsevierStylePara elsevierViewall">Although the results of the current study are similar to those reported in the literature, they reveal important new information. The following studies support our results: Li et al.<a class="elsevierStyleCrossRef" href="#bib0013"><span class="elsevierStyleSup">13</span></a> showed that miR-99b is down-regulated in the liver metastasis of CRC; Fujino et al.<a class="elsevierStyleCrossRef" href="#bib0014"><span class="elsevierStyleSup">14</span></a> reported that downregulation of microRNA-100/microRNA-125b is related to lymph node metastasis in early CRC; and Zheng et al.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">15</span></a> reported that the long noncoding RNA HAGLROS adjusts apoptosis and autophagy in CRC cells by sponging miR-100 to target ATG5 expression.

First, the most important limiting factor of our study was its small sample size. Second, although KRAS mutations were detected in most patients, they were not detected in all patients.

This indicates that they play an important role in PC and LVM. While miR-99b expression was highest in the primary tumor, its decrease in LVM suggests that miR-99b may have a protective effect against liver metastasis. In contrast, the detection of miR-135 in the PC and LVM compared with the main tissue suggests that it promotes progression to PC and LVM.
