Brief Summary

For limited-stage small cell lung cancer (SCLC), surgical treatment is recommended for patients with T1-2N0M0 (I-IIA) by guidelines. However, whether perioperative immunotherapy extends radical surgery to stage IIB-IIIB patients with improved survival remains elusive.

This is a phase II, single-arm study to evaluate the efficacy and safety of neoadjuvant Tislelizumab + chemotherapy (Cisplatin/Carboplatin + Etoposide) followed by radical surgery and adjuvant Tislelizumab ± chemotherapy for patients with limited-stage SCLC.

Conditions

Perioperative Immunotherapy; Limited Stage Lung Small Cell Carcinoma; Resectable Small Cell Lung Cancer

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Perioperative Tislelizumab combined with Etoposide and Platinum-based Chemotherapy

Neoadjuvant therapy: Tislelizumab 200mg, i.v., q3w, 2-4 cycles; Cisplatin 75mg/m2, d1 or Carboplatin AUC5-6, d1 + Etoposide 100mg/m2, d1-3, q3w, 2-4 cycles.

Those resectable after neoadjuvant therapy will be treated with radical surgery.

Adjuvant therapy: Patients received radical surgery will be treated with Tislelizumab plus platinum-etoposide therapy (the total cycle of perioperative chemotherapy is four), followed by Tislelizumab monotherapy for one year.

Group Type: EXPERIMENTAL

Neoadjuvant therapy: Tislelizumab + Cisplatin or Carboplatin + Etoposide; Adjuvant therapy: Tislelizumab + Cisplatin or Carboplatin + Etoposide (the total cycle of perioperative chemotherapy is four), followed by Tislelizumab monotherapy for one year.
