BACKGROUND: Managing malignant pleural effusion (MPE) with pleurodesis is essential for symptom relief and minimizing the need for repeated thoracentesis. Interstitial lung disease (ILD) is one of the most common complications associated with advanced lung cancer. However, the efficacy and safety of pleurodesis for MPE secondary to lung cancer with ILD remains unclear. This study aimed to evaluate the efficacy and safety of pleurodesis in this population.
METHODS: This study was a single-center retrospective analysis. The cases of pleurodesis in patients with MPE secondary to lung cancer complicated with ILD at Nippon Medical School Hospital (Tokyo, Japan) between January 2010 and December 2022 were included.
RESULTS: Of the 26 lung cancer patients with ILD who underwent pleurodesis were analyzed. Fourteen patients received talc and 12 patients received minocycline, respectively. Talc was used in 10 out of 14 patients with drug-induced ILD and radiation-induced lung injury (RILI). In contrast, minocycline was used in 10 out of 12 patients with idiopathic interstitial pneumonias (IIPs). One month after pleurodesis, the efficacy for pleural adhesions was 64.3% and 50.0% in the talc and minocycline groups. The presence of a partially expanded lung before pleurodesis was a predictive factor for failure [odds ratio: 7.00, 95% confidence interval (CI): 1.20-40.83, P=0.04]. When excluding the patients presenting partially expanded lung, the efficacy rate was 77.8% and 71.4% in the talc and minocycline groups. One case of grade 5 acute respiratory distress syndrome (ARDS) was observed in each group. All cases developing ARDS had been treated with systemic prednisolone against ILDs presenting ground glass opacity and consolidation within 6 months before pleurodesis.
CONCLUSIONS: Pleurodesis is considered to be one of the treatment options against MPE in patients with ILD. However, two cases of ARDS were observed; thus, clinicians should carefully consider the indication of pleurodesis in the patients who had the recent onset of ILD and were treated with systemic prednisolone.
