Survival analysis indicated that higher expression levels of JUN and CXCL8 were negatively correlated with prognosis in lung cancer patients, with the negative correlation being particularly significant between JUN and lung squamous cell carcinoma patients, and between CXCL8 and lung adenocarcinoma patients (Figure 5L-5M). Here, CXCL8 is linked to squamous cell lung carcinoma.
