For example, in tongue squamous cell carcinoma (TSCC), the higher level of caveolin‐1 (CAV1) in exosomes is negatively correlated with recurrence and survival.159 In nasopharyngeal carcinoma (NPC), the level of miR‐24‐3p was higher in exosomes from patients compared with healthy people and was correlated with lower disease‐free survival.154. Here, CAV1 is linked to nasopharyngeal carcinoma.
