Immunotherapy and Chemotherapy Versus Sleep Disturbances for NSCLC Patients.

INTRODUCTION

Cancer patients are known to experience sleep disturbances that differ between disease stages and treatments. Regarding lung cancer patients and immunotherapy, information on their sleep disturbances has been recently acquired, but no comparison has been made between different treatment modalities.

PATIENTS AND

METHODS

We recruited 98 non-small cell lung cancer patients; 49 had programmed death-ligand 1 expression of ≥50% and received immunotherapy as first-line treatment and 49 had programmed death-ligand 1 expression in the range from 0-49 and received chemotherapy as first-line treatment. All patients were stage IV, but with no bone metastasis. Sleep disturbances were recorded through polysomnography and sleep questionnaires.

RESULTS

For immunotherapy patients with PD-L1 expression ≥ 50%, the disease response was rapid and the sleep disturbances decreased rapidly. On the other hand, for chemotherapy patients, the sleep disturbances remained for all those patients that had partial response and stable disease. It was noticed that chemotherapy drugs induce severe adverse effects.

DISCUSSION: In our study, it was observed that patients with complete response had reduced sleep disturbances in the case of immunotherapy patients. However, sleep disturbances continued for several patients in the chemotherapy group due to the adverse effects of chemotherapy drugs.

IN

CONCLUSION

Immunotherapy drugs on their own do not induce sleep disturbances and, through treatment response, alleviate sleep disturbances in lung cancer patients.
