Efficacy and safety of combined anlotinib-oral etoposide treatment for patients with platinum-resistant ovarian cancer

Despite the availability of numerous treatment options, managing patients with platinum-resistant ovarian cancer (PROC) remains challenging, and the prognosis of PROC is notably unfavorable. This retrospective study aimed to assess the efficacy and safety of combined anlotinib-oral etoposide treatment for patients with PROC. Data of 23 patients who were diagnosed with PROC from January 2020 to November 2022 and treated with anlotinib combined with oral etoposide for at least 2 cycles were retrospectively analyzed. Among per-protocol patients, 9 (45.0%; 95% confidence interval [CI]=21.1-68.9) of 20 patients achieved partial response and 17 (85.0%, 95% CI=67.9-100.0) of 20 patients achieved disease control. The median progression-free survival was 8.7 months (95% CI=5.3-11.6). The incidence of adverse events (any grade) was 100%, and the incidence of grade 3-4 adverse events was 54.5%. Anlotinib combined with etoposide emerged effective for the treatment of PROC.

Integrative Analysis of Shared Pathogenic Genes and Potential Mechanisms in Gardnerella vaginalis and Persistent HPV16 Infection

Bacterial vaginosis, often accompanied by Gardnerella vaginalis (GV) overgrowth, is associated with persistent high‐risk human papillomavirus (HR‐HPV) infection, particularly HPV16. This study integrated transcriptomic data from in vitro GV infection experiments and a GEO dataset (GSE75132) of HPV16 persistence to elucidate shared pathogenic mechanisms. Differential expression analysis identified 4115 genes modulated by GV infection and 861 by HPV16 persistence, with 74 common differentially expressed genes (DEGs) displaying consistent trends. Enrichment analyses revealed that these DEGs participate in metabolic pathways, immune defense, host–pathogen interactions, and carcinogenesis. Protein–protein interaction networks and Random Forest (RF) feature selection pinpointed radical S‐adenosyl methionine domain containing 2 (RSAD2) and Interferon‐induced protein with tetratricopeptide repeats 1 (IFIT1) as central hub genes. Upstream transcription analysis identified the homer_AGTTTCAGTTTC_ISRE motif and established a ceRNA network involving hsa‐miR‐654‐5p, IFIT1/RSAD2, and lncRNAs. Mendelian randomization (MR) and colocalization analyses linked RSAD2 downregulation to an increased risk of cervical carcinoma in situ (rs2595163, PPH4 = 0.62), while ROC analysis demonstrated strong diagnostic potential for the combined hub gene expression. Notably, single‐cell transcriptomics revealed distinct RSAD2 and IFIT1 expression patterns in immune and epithelial cells during the progression from HPV infection to cervical cancer. Collectively, these findings support RSAD2 and IFIT1 as promising biomarkers and therapeutic targets for HPV‐related cervical lesions.
