Objective applying Excel software accompany with Visual Basic program tools to explore how does the expression level of miR-501 in tumor tissue affect the survival time of lung squamous cell carcinoma patients.
Methods Obtain the data of the survival time of lung Squamous cell carcinoma patients and the expression level of miR-501 in their tumor tissue from Kmplot databases. Import them into Excel software. Draw Graph User Interface and Write program to perform survival analysis of these lung Squamous cell carcinoma patients.
Result Lung Squamous cell carcinoma patients who have a higher expression level of miR-501 live longer than ones who have a lower expression level of miR-501. The log-rank test between higher miR-501 group and lower miR-501 group shows difference of survial time between two group was statistically significant(P<0.05).
Conclusion Excel with Visual Basic program tools contributes great in survival analysis and log-rank test of survival analysis data of cancer patients. The result is credible.
