Combination of anlotinib and second-line chemotherapy as surrogate to reduce immunosuppression in patients with advanced non-small cell lung cancer.

OBJECTIVE

To study the clinical effects of anlotinib combined with second-line chemotherapy (SLC) on immunosuppression in patients with advanced non-small cell lung cancer (NSCLC).

METHODS

In this retrospective study, the medical records of 106 patients with advanced NSCLC admitted to the Lianyungang First People's Hospital from November 2020 to March 2022 were retrospectively analyzed. Amongst 106 patients, 53 patients received second-line single-agent chemotherapy regimens (SLC group), and 53 patients received anlotinib combined with SLC (ASLC group). Prognosis, levels of immune cells and inflammatory cytokine, and adverse reactions were analyzed.

RESULTS

Clinical efficacy of the ASLC group was significantly higher than the SLC group (p<0.05). After treatment, patients in the ASLC group exhibited significantly higher levels of CD4+/CD8+ and CD4+ compared to those in the SLC group (p<0.05), while the difference in CD8+ level between the two groups was not statistically significant (p>0.05). After treatment, levels of tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), interleukin-8 (IL-8), interleukin-6 (IL-6) in the ASLC group were lower compared to the SLC group (p<0.05).

CONCLUSION

In patients with advanced NSCLC, anlotinib combined with SLC is associated with higher levels of immune cells and reduced inflammatory factors. This treatment regimen, thus, can reduce immunosuppression and improve the prognosis of NSCLC patients.
