To further explore prognosis-related lncRNAs for HNSCC, intersection was taken between the survival-related brown co-expression module and the constructed ceRNA network, yielding a set of 5 survival-related DELs: MIR4435-2HG, CASC9, LINC01980, STARD4-AS1 and MIR99AHG. Here, STARD4 is linked to head and neck squamous cell carcinoma.
