A Study on the Efficacy of Androgen Deprivation Therapy Combined With Anti-PD-1 Therapy in Advanced Lung Cancer

Summary

Androgen Deprivation Therapy (ADT) triggers thymic revitalization and increases thymic output, enhancing baseline anti-tumor immunity and responses to immunotherapies. Anti-tumor synergism has been identified by combining ADT with anti-PD-1 immunotherapy for androgen-independent tumors. This study is to investigate the combination of Leuprorelin ADT and Sintilimab (anti-PD-1) therapy in patients with advanced lung cancer.

Eligibility

3.Inclusion Criteria:

1. Male patients aged ≥60 years.
2. ECOG performance status score of 0 \~1.
3. Expected survival time of more than 3 months.
4. Histologically or cytologically diagnosed advanced lung cancer according to the TNM staging system established by AJCC.
5. Patients who have not previously received any anti-PD-1 treatment.
6. Patients with adequate bone marrow function, no significant hepatic, renal, or coagulation dysfunction as per laboratory test criteria.
7. At least one tumor lesion meeting the following criteria:

   * No prior local treatments such as radiotherapy
