Brief summary (registry, in English)
This study aims to reveal the molecular characteristics and immune microenvironmental profile of signet ring cell carcinoma of the lung (LSRCC) in the Chinese population through integrated multi-omics analyses. The project plans to enroll formalin-fixed paraffin-embedded (FFPE) tissue samples and paired adjacent tissues from 39 patients with previously untreated LSRCC to establish a Chinese LSRCC molecular database. Whole-exome sequencing (WES) will be used to analyze gene mutations, such as single nucleotide variants (SNVs), copy number variants (CNVs), and fusion events. RNA-seq will be used to screen for differentially expressed genes (DEGs) and perform immunophenotyping, while multiplex immunohistochemistry will be employed to quantify the tumor immune microenvironment (TIME). The successful implementation of this project is expected to identify novel molecular biomarkers specific to the Chinese LSRCC population, enhance understanding of the unique immune phenotypes within this group, and-combined with clinical follow-up-establish correlations between molecular/immune signatures and therapeutic efficacy assessments, thereby providing evidence-based medical support for subsequent personalized precision diagnosis and treatment of LSRCC in this population.
