The survival date from the samples of TCGA was also available. Overall survival (OS) and progression-free survival(PFS) were thought to be the indicators for the exploration of relevancy between LASTR expression and patient prognosis. With respect to survival analyses, the Kaplan-Meier method and log-rank test were adopted in each cancer type. The survival curves were drawn using R packages “survival” and “survminer”. Besides, the R packages “forestplot” was used to figure out the relationship between LASTR expression and survival in pan-cancer.
