Abstract

Introduction

Extensive small cell lung cancer (ES-SCLC) are currently managed using first-line chemotherapy options, including atezolizumab (Atezo) plus etoposide and carboplatin (CE) or durvalumab (Durva) plus etoposide with either cisplatin (PE) or carboplatin (CE). However, a definitive distinction in therapeutic effects between Atezo and Durva in these regimens remains unestablished.

Methods

We analyzed data from 100 patients diagnosed with ES-SCLC who received immune checkpoint inhibitors (ICIs) as first-line chemotherapy. Among them, 70 were administered Atezo + CE, 12 received Durva + PE, and 18 received Durva + CE. We assessed the efficacy of the two ICIs across various factors.

Results

The progression-free survival (PFS) and overall survival (OS) did not significantly differ between Atezo + CE and Durva + CE/PE as first-line chemotherapy treatments for SCLC. We observed no significant differences in age, sex, performance status (PS), liver metastasis, bone metastasis, or platinum-based agent usage between the treatment cohorts. However, a marked improvement in PFS and OS was observed in the solitary patient with brain metastasis treated with Atezo + CE.

Conclusion

The primary distinction between these treatments was observed in the management of patients with brain metastasis. The literature lacks comparative studies on the effects of first-line ICI treatment on the central nervous system, rendering our findings significant in clinical practice. Despite the retrospective nature of this study and the potential for various biases, we recommend the preferential use of Atezo + CE in patients with brain metastasis to potentially enhance prognosis.

期刊介绍： Cancer Medicine is a peer-reviewed, open access, interdisciplinary journal providing rapid publication of research from global biomedical researchers across the cancer sciences. The journal will consider submissions from all oncologic specialties, including, but not limited to, the following areas: Clinical Cancer Research Translational research ∙ clinical trials ∙ chemotherapy ∙ radiation therapy ∙ surgical therapy ∙ clinical observations ∙ clinical guidelines ∙ genetic consultation ∙ ethical considerations Cancer Biology: Molecular biology ∙ cellular biology ∙ molecular genetics ∙ genomics ∙ immunology ∙ epigenetics ∙ metabolic studies ∙ proteomics ∙ cytopathology ∙ carcinogenesis ∙ drug discovery and delivery. Cancer Prevention: Behavioral science ∙ psychosocial studies ∙ screening ∙ nutrition ∙ epidemiology and prevention ∙ community outreach. Bioinformatics: Gene expressions profiles ∙ gene regulation networks ∙ genome bioinformatics ∙ pathwayanalysis ∙ prognostic biomarkers. Cancer Medicine publishes original research articles, systematic reviews, meta-analyses, and research methods papers, along with invited editorials and commentaries. Original research papers must report well-conducted research with conclusions supported by the data presented in the paper.
