Tislelizumab plus chemotherapy before and after surgery for resectable limited-stage small cell lung cancer

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-arm phase II trial gives neoadjuvant tislelizumab combined with cisplatin or carboplatin plus etoposide, followed by radical (R0) surgical resection and adjuvant tislelizumab with or without chemotherapy for patients with resectable limited-stage SCLC (AJCC 8th IIB–IIIB). Eligible patients will undergo staging with imaging and invasive sampling to confirm resectability and then receive combined immunochemotherapy prior to surgery. The study will track surgical feasibility, pathological response rates, safety and adverse events, and clinical outcomes such as progression-free and overall survival. Results will help clarify whether perioperative PD-1 blockade can safely extend curative surgical approaches to a broader group of limited-stage SCLC patients.

   TNM staging includes T3-4 (N0 only) or N1-2 (any T) and M0, where T4 is limited to tumors \>7 cm in diameter; Patients with tumors invading the diaphragm, mediastinum, heart, great vessels, trachea, recurrent laryngeal nerve, esophagus, vertebral body, carina or having separate tumor nodules in different ipsilateral lobes are excluded. N2 is limited to single station and non-bulky.
5. No prior radiotherapy, chemotherapy, immunotherapy, surgery or other systemic treatments;
6. ECOG PS score of 0-1;
7. Expected survival must be \>3 months;
8. Adequate bone marrow reserve and organ function within 30 days prior to enrollment meeting criteria for receiving platinum-based doublet chemotherapy;
9. No contraindications for immunotherapy.

Exclusion Criteria:

1. Tumor histopathology indicates non-small cell lung cancer (NSCLC);
2. Presence of clinically inactive or active brain metastases;
3. Any history of interstitial lung disease (ILD) (including pulmonary fibrosis or radiation pneumonitis), current ILD, or suspicion of such diseases based on imaging during screening;
4. Receiving systemic corticosteroid therapy within 14 days prior to the first dose of study drug;
5. Previous radiotherapy, chemotherapy, immunotherapy, surgery, or other systemic treatments;
6. Any active malignancy within 2 years prior to enrollment;
7. Women who are pregnant, breastfeeding, or planning to become pregnant during the study period;
8. Uncontrolled or significant cardiovascular disease at the time of enrollment;
