PD-L1/PD-1 Inhibitors Plus Chemotherapy Versus Chemotherapy Alone for the Neoadjuvant Treatment of Limited-stage SCLC

Korábbi kezelés

• Patients who have received anti-tumor treatment for SCLC (including but not limited to chemotherapy and radiation therapy at the site of the lesion).
• Patients who have previously used immune checkpoint inhibitors such as PD-1/PD-L1 inhibitors for treatment.
• Patients deemed by the investigator to have concomitant diseases that pose a serious risk to patient safety or could affect the patient's ability to complete the study.
• Patients who have undergone major surgery within 4 weeks prior to treatment initiation, or those with significant trauma or fractures, or those with unhealed wounds at the time of treatment.
• Patients with comorbidities that make them unsuitable for surgery.
