The high mortality rate is due to a poor prognosis and is often diagnosed as having advanced stages. If it is known at the initial stage, the prognosis of lung cancer will be better. Prognosis can be predicted with a marker of prognostic biology, one of which is micro RNA(mi RNA). This study aims to prove that serum mi RNA can be predictive biological marker and prognosis in NSCLC patients in Indonesia.Methods This study was cohort retrospective among 52 subjects in "Dharmais" Hospital National Cancer Center. Sample was obtained from patients’ serum. Mi R-34, mi R-148, mi R-155 and mi R-222 serum are measured through Real-Time PCR(q PCR). Data were analyzed and interpreted with descriptive analysis, bivariate analysis(Mann Whitney-U for two type of variables or Kruskal-Wallis for more than two type of variables. Kaplan-Meier analysis was used to know association between characteristic which are sociodemographic, performance status, clinico-pathology, and survival rate in mi RNA expression. Results From this study, mi RNA expression: mi R-34(46.15%), mi R-148(23.08%), mi R-155(40.38%) and mi R-222(32.69%). Performance status score was statistically significant correlation with mi R-148(P=0.049) and mi R-222(P=0.018). High mi R-34 is associated with multiple M1 b metastatic type(P=0.020), cancer cell type(adenocarcinoma, P=0.009) and adenocarcinoma epidermal growth factor receptor(EGFR) mutation(negative, P=0.031). There was a significant correlation between the high mi R-222 as a poor prognosis in advanced stage NSCLC with M1 b metastasis(Median Survival/MS: 27 d, P=0.049) and positive EGFR mutations(MS: 74 d, P=0.049) and correlation of mi R-155 with adenocarcinoma(MS: 69 d, P=0.034) and positive EGFR gene mutations(MS: 58 d, P=0.023).Conclusion High mi R-34 expression in advanced stage NSCLC is the predictive factor for multiple metastatic, adenocarcinoma cell type and adenocarcinoma negative EGFR mutation. High expression of mi R-155 and mi R-222 are poor prognoses, especially high mi R-222 found in metastasis M1 b and positive EGFR mutation and mi R-155 found in adenocarcinoma and positive EGFR gene mutations. Further studies regarding correlation between mi RNA and survival rate are needed.展开更多
