Core Tip
Core Tip: The application of molecular targeted agents and immune checkpoint inhibitors have greatly improved the prognosis of advanced renal cell carcinoma (RCC). We report a patient with advanced RCC treated with multiple lines of molecular targeted agents, who developed a Pneumocystis jirovecii pneumonia after treatment with everolimus in combination with lenvatinib. The pathogenic organism was identified by next-generation sequencing (NGS) of bronchoscopic alveolar lavage fluid (BALF) and successfully treated with trimethoprim-sulfamethoxazole. Evaluating BALF with NGS technology might be used to detect pathogens and determine the correct treatment plan for patients with rare infections caused by the use of molecular targeted agents.
