The phase III ASTRUM-005 study (NCT04063163) has demonstrated promising antitumor efficacy and well tolerability of first-line serplulimab combined with chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). However, due to the strict eligibility criteria of randomized controlled trials (RCTs), real-world data on patients with more complex and varied conditions are currently lacking. This highlights the urgent need for real-world evidence to better understand the practical effectiveness and safety of treatments. ASTRUM-005R is a multicenter real-world study conducted in China, designed to evaluate the efficacy and safety of the first-line treatment serplulimab-based immunochemotherapy for ES-SCLC in real-world clinical practice. Additionally, it aims to compare its findings with the data of the randomized controlled phase III ASTRUM-005 trial (descriptive), providing insights into optimal treatment strategies for this patient population.

2. No prior systemic therapy for the diagnosis of ES-SCLC;
3. Patients previously treated with chemoradiation for limited-stage SCLC: must be treatment with curative intent and have a treatment-free interval of at least 6 months between the last dose of chemotherapy/last course, end of thoracic radiotherapy or chemoradiation and confirmation of ES-SCLC;
4. At least two cycles of treatment with Serplulimab in combination with chemotherapy with one or more documented efficacy assessments ;
5. Local radiotherapy is allowed for patients indicated for radiotherapy, including but not limited to thoracic radiotherapy, brain radiotherapy.
Exclusion Criteria:
1. Incomplete clinical information, such as no disease course, pathological diagnosis, treatment and observation of outcome data;
2. Patients with SCLC and other malignancies.
Primary outcome measure(s)
Progression-free survival (PFS) — 1yaer defined as the time from the start of chemotherapy to the first occurrence of disease progression or death due to any cause, assessed by the physician according to RECIST 1.1, with the response assessment record as the determination standard
