A combined model of circulating tumor DNA methylated SHOX2/SCT/HOXA7 and clinical features facilitates the discrimination of malignant from benign pulmonary nodules.

Background: Despite the advancements in early lung cancer detection attributed to the widespread use of low-dose computed tomography (LDCT), this technology has also led to an increasing number of pulmonary nodules (PNs) of indeterminate significance being identified. Therefore, this study was aimed to develop a model that leverages plasma methylation biomarkers and clinical characteristics to distinguish between malignant and benign PNs.

Methods: In a training cohort of 210 patients with PNs, we evaluated plasma circulating tumor DNA (ctDNA) for the presence of three lung cancer-specific methylation markers: SHOX2, SCT, and HOXA7.

Anlotinib is effective, tolerable, and convenient in administration as a third-line treatment for NSCLC. This study aimed to evaluate the efficacy and safety of maintenance therapy with anlotinib after platinum-based induction chemotherapy for patients with advanced NSCLC.

Novel cell states arise in embryonic cells devoid of key reprogramming factors.

The capacity for embryonic cells to differentiate relies on a large-scale reprogramming of the oocyte and sperm nucleus into a transient totipotent state. In zebrafish, this reprogramming step is achieved by the pioneer factors Nanog, Pou5f3, and Sox19b (NPS). Yet, it remains unclear whether cells lacking this reprogramming step are directed towards wild type states or towards novel developmental canals in the Waddington landscape of embryonic development.

and encode micropeptides that regulate chromatin accessibility in vertebrate-specific neural cells.

Thousands of long intergenic non-coding RNAs (lincRNAs) are transcribed throughout the vertebrate genome. A subset of lincRNAs enriched in developing brains have recently been found to contain cryptic open-reading frames and are speculated to encode micropeptides. However, systematic identification and functional assessment of these transcripts have been hindered by technical challenges caused by their small size.

Sintilimab plus chemotherapy for patients with EGFR-mutated non-squamous non-small-cell lung cancer with disease progression after EGFR tyrosine-kinase inhibitor therapy (ORIENT-31): second interim analysis from a double-blind, randomised, placebo-controlled, phase 3 trial.

Background: In the first interim analysis of the ORIENT-31 trial, compared with chemotherapy alone, sintilimab plus bevacizumab biosimilar IBI305 plus chemotherapy (pemetrexed and cisplatin) significantly improved progression-free survival in patients with EGFR-mutated non-squamous non-small-cell lung cancer (NSCLC) who progressed on EGFR tyrosine-kinase inhibitor treatment. However, the benefit of anti-PD-1 or PD-L1 antibody added to chemotherapy in this patient population remains unclear, with no prospective evidence from phase 3 trials globally. We report the results from the prespecified second interim analysis of progression-free survival between sintilimab plus chemotherapy and chemotherapy alone, the updated results of sintilimab plus IBI305 plus chemotherapy, and preliminary overall survival results.
