So I have obtained the differentially expressed genes from Series GSE65626 using geo2r. However, I'm not able to use https://kmplot.com/analysis/ for survival analysis. It was mentioned that I needed to have columns such as "survival time" and "survival event" but, I those details were not available in the dataset. Is there any alternative for me to perform survival analysis for this dataset?

I am afraid that performing a survival analysis without having survival information in hand will be tricky. Do you have other kind clinical data? You need some "time to event" column, and an "event" column in order to perform a survival analysis. For example, the event (in addition to survival), could be a relapse. If you have a column with information regarding whether it has been a relapse or not, and the time to relapse, you could run a survival analysis based on the Progression-Free Survival (PFS).
