Summary

This study plans to enroll limited-stage small cell lung cancer (LS-SCLC) patients who have achieved disease control after concurrent chemoradiotherapy (cCRT). Tissue samples collected at initial diagnosis and serial peripheral blood samples obtained at multiple post-cCRT timepoints will be analyzed using targeted next-generation sequencing to investigate the correlation between molecular residual disease (MRD) status and tumor recurrence/metastasis. For patients with MRD-positive results, a therapeutic strategy combining immunotherapy with anti-angiogenic agents will be implemented with the aim of improving clinical outcomes.

Conditions

  • Small Cell Lung Carcinoma

Interventions

DRUG

Adebrelimab Injection

Patients with MRD Positive will receive adebrelimab (1200 mg, D1, Q3W) , followed by ctDNA monitoring every 2 months (Year 1) and every 3 months (Year 2).The above treatment regimen will be maintained until disease progression, intolerable toxicity, completion of two years of treatment, subject-initiated withdrawal, or investigator-determined discontinuation.

DRUG

Apatinib Mesylate Tablets

Apatinib Mesylate Tablets (250 mg, QD) , followed by ctDNA monitoring every 2 months (Year 1) and every 3 months (Year 2).The above treatment regimen will be maintained until disease progression, intolerable toxicity, completion of two years of treatment, subject-initiated withdrawal, or investigator-determined discontinuation.
