Cost-effectiveness analysis of benmelstobart, anlotinib, and chemotherapy in extensive-stage small-cell lung cancer.

Background: The ETER701 trial assessed the efficacy and safety of benmelstobart combined with anlotinib plus etoposide/cisplatin (BEN-AL-EC) as a first-line therapy for extensive-stage small-cell lung cancer (ES-SCLC). Results indicated that BEN-AL-EC, when compared with placebo in combination with etoposide/cisplatin (PLB-EC), significantly enhanced both progression-free and overall survival rates, while demonstrating an acceptable safety profile among patients with ES-SCLC. However, BEN-AL-EC is expensive, necessitating its cost-effectiveness analysis.

Advances in Noninvasive Molecular Imaging Probes for Liver Fibrosis Diagnosis.

Liver fibrosis is a wound-healing response to chronic liver injury, which may lead to cirrhosis and cancer. Early-stage fibrosis is reversible, and it is difficult to precisely diagnose with conventional imaging modalities such as magnetic resonance imaging, positron emission tomography, single-photon emission computed tomography, and ultrasound imaging. In contrast, probe-assisted molecular imaging offers a promising noninvasive approach to visualize early fibrosis changes in vivo, thus facilitating early diagnosis and staging liver fibrosis, and even monitoring of the treatment response.
