Purpose:The current study aims to explore the effect of myocardial infarction associated transcript (MIAT) level on the long-term prognosis of hand-assisted laparoscopic colectomy (HALC) or laparoscopic-assisted colectomy (LAC) for colorectal cancer (CC).Materials and Methods:A total of 320 CC patients were included. Patients were randomized into HALC and LAC group.Results:MIAT level in CC tissue was upregulated, and had a significant positive association with its level in serum. MIAT levels in both CC tissue and serum were correlated with lymph node metastasis and histologic grading. Survival analysis showed that the overall survival rate in 3 years after operation was significantly lower in HALC-High MIAT group (P<0.05). When MIAT level is <10.9 in CC tissue or 8.7 in serum, 100% of patients who underwent HALC will be alive for >3 years.Conclusions:For patients with low MIAT level, both HALC and LAC are available, otherwise, LAC is more recommended.
