| Summary | 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).

| Who can participate | Inclusion Criteria: 1.Histologically confirmed, previously untreated LSRCC; 2. Adequate FFPE tumor tissue and paired adjacent non-tumor tissue available; 3. Expected survival ≥ 12 weeks; 4. Patients (or their legal guardians) willing and able to provide written informed consent; 5.Availability of complete pathology and imaging data. Exclusion Criteria: 1\. Prior systemic anticancer therapy; 2. Secondary LSRCC (i.e., metastatic signet ring cell carcinoma originating from a non-lung primary site); 3. Concurrent other malignancies; 4. Incomplete pathology results, missing imaging data, or unreliable follow-up information; 5. Pregnancy or lactation |
