Abstract
Background: Malignant pleural effusion (MPE) remains a negative prognostic factor in non-small cell lung cancer (NSCLC), even after the emergence of immune checkpoint inhibitors. Vascular endothelial growth factor (VEGF) plays a pivotal role in the pathogenesis of MPE. Bevacizumab, a humanized monoclonal antibody against VEGF, is a key agent for patients who develop MPE. However, it is unclear whether MPE is a poor prognostic factor in patients with advanced non-squamous NSCLC receiving treatment with the atezolizumab plus bevacizumab, carboplatin, and paclitaxel (ABCP) regimen. Moreover, the effect of ABCP on MPE control is unknown. This study aimed to elucidate the efficacy and safety of ABCP for non-squamous NSCLC patients with MPE.
Methods: We retrospectively analyzed consecutive patients with advanced non-squamous NSCLC who received treatment with ABCP (January 2019-September 2023). Patients were divided into two groups (non-MPE and MPE), and treatment outcomes were compared. In the MPE group, treatment efficacy for MPE control and toxicity were evaluated.
Results: Of the 46 patients enrolled, 17 and 29 were included in the non-MPE and MPE groups, respectively. The objective response and disease control rates were not significantly different between the non-MPE and MPE groups (76.5% vs. 51.7%, P=0.13; 88.2% vs. 82.8%, P>0.99; respectively). Similarly, the median progression-free survival and median overall survival were not significantly different (9.9 vs. 10.1 months, P=0.87; 16.0 vs. 19.9 months, P=0.87, respectively). In the MPE group, 25 patients (86.2%) achieved MPE control lasting >8 weeks from the initiation of treatment with ABCP; the median progression-free survival without an unequivocal increase in MPE was 15.0 months. The incidence rates of grade ≥3 non-immune- and immune-related adverse events were 83% and 17%, respectively. There was no treatment-related death.
Conclusions: The ABCP regimen may be a promising treatment option for non-squamous NSCLC patients with MPE.

Translational Lung Cancer Research(TLCR, Transl Lung Cancer Res, Print ISSN 2218-6751; Online ISSN 2226-4477) is an international, peer-reviewed, open-access journal, which was founded in March 2012. TLCR is indexed by PubMed/PubMed Central and the Chemical Abstracts Service (CAS) Databases. It is published quarterly the first year, and published bimonthly since February 2013. It provides practical up-to-date information on prevention, early detection, diagnosis, and treatment of lung cancer. Specific areas of its interest include, but not limited to, multimodality therapy, markers, imaging, tumor biology, pathology, chemoprevention, and technical advances related to lung cancer.
