Purpose: To evaluate whether the addition of a poly (ADP-ribose) polymerase inhibitor (PARPi) talazoparib to maintenance immune checkpoint inhibitor (ICI) atezolizumab following frontline chemoimmunotherapy improved outcomes in patients with Schlafen 11 (SLFN11)-positive extensive stage small cell lung cancer (ES-SCLC).
Methods: Patients with newly diagnosed SLFN11 expressing (H-score ≥ 1, evaluated centrally) ES-SCLC were randomized to maintenance atezolizumab (A) versus atezolizumab plus talazoparib (AT) following frontline chemotherapy plus atezolizumab. The primary objective was to compare progression-free survival (PFS) using a 1-sided 10% level stratified log-rank test. Secondary endpoints included objective response rate (ORR), overall survival (OS), and toxicity. Target sample size was 84 eligible patients.
Results: From June 15, 2020 to December 15, 2022, 106 eligible patients were randomized (54 to AT and 52 to A). PFS was improved with AT versus A (hazard ratio [HR], 0.66; 80% confidence interval [CI]: 0.50-0.86; 1-sided P = 0.019) with a median PFS of 2.9 and 2.4 months; OS was not different between groups (HR, 0.98; 80% CI: 0.71-1.36; 1-sided P = 0.47). Grade ≥ 3 non-hematologic treatment-related adverse events (TRAEs) occurred in 17% of patients with AT and 14% of patients with A. Grade ≥ 3 hematological TRAEs were more common in AT (50%) than in A (4%) (P < 0.001).
Conclusion: Maintenance AT improved PFS in patients with SLFN11-positive ES-SCLC that did not progress following initial chemo-immunotherapy. Hematologic toxicity, primarily grade 3 anemia, was increased with AT, as expected. Prospective biomarker-selection was demonstrated, paving the way for future evaluation of novel therapies in molecularly defined SCLC populations.

Objectives
The use of tumor-informed circulating tumor DNA (ctDNA) testing in patients with early-stage disease before surgery is limited, mainly owing to restricted tissue access and extended turnaround times. This study aimed to evaluate the clinical value of a tumor-naïve, methylation-based cell-free DNA assay in a large cohort of patients with resected NSCLC.
Method
We analyzed presurgical plasma samples from 895 patients with EGFR and anaplastic lymphoma kinase-wild-type, clinical stage I or II NSCLC. The ctDNA status was evaluated for its prognostic significance in relation to tumor volume, metabolic activity, histologic diagnosis, histologic subtypes, and clinical-to-pathologic TNM upstaging.
Results
Presurgical ctDNA detection was observed in 55 of 414 patients (13%) with clinical stage I lung adenocarcinoma (LUAD) and was associated with poor recurrence-free survival (2-year recurrence-free survival 69% versus 91%; log-rank p < 0.001), approaching that of clinical stage II LUAD. Presurgical ctDNA detection was not prognostic in patients with clinical stage II LUAD or non-LUAD. Within LUAD, tumor volume and positron emission tomography avidity interacted to predict presurgical ctDNA detection. Moreover, presurgical ctDNA detection was predictive of the postsurgical discovery of International Association for the Study of Lung Cancer grade 3 tumors (p < 0.001) and pathologic TNM upstaging (p < 0.001). Notably, presurgical ctDNA detection strongly correlated with higher programmed death-ligand 1 expression in tumors (positive rates 28% versus 55%, p < 0.001), identifying a subgroup likely to benefit from anti–programmed death-ligand 1 therapies.
Conclusion
These findings support the integration of ctDNA testing into routine diagnostic workflows in early-stage NSCLC without the need for tumor tissue profiling. Furthermore, it is clinically useful in identifying patients at high risk who might benefit from innovative treatments, including neoadjuvant immune checkpoint inhibitors.

Introduction
Tyrosine kinase inhibitors (TKIs) are first-line treatment options for ALK-positive (ALK+) NSCLC. Factors such as variant allele frequencies (VAFs), EML4-ALK fusion variant, and concurrent TP53 mutations (TP53mt) in circulating tumor DNA (ctDNA) may affect treatment outcomes. We evaluated their effects on time to discontinuation (TTD) of first-line treatment with next-generation ALK TKIs in a real-world setting.
Methods
Adults with advanced or metastatic NSCLC and ctDNA-detected ALK fusion who received first-line next-generation ALK TKI monotherapy were identified in GuardantINFORM. Effects of ALK fusion VAF, EML4-ALK variants, and TP53mt detection on TTD were evaluated.
Results
A total of 307 patients with ALK fusion in baseline ctDNA received first-line alectinib (n = 280), brigatinib (n = 15), lorlatinib (n = 9), or ceritinib (n = 3); 150 patients (49%) had ALK-fusion VAF greater than or equal to 1%. Among 232 patients with EML4-ALK fusions (v1, 50%; v3, 36%), TP53mt co-occurred with v1 in 42 (18%) and v3 in 32 (14%). Patients with VAF less than 1% versus greater than or equal to 1% had a median TTD of 32.2 (95% confidence interval [CI]: 20.7–not estimable [NE]) versus 14.7 months (10.4–19.9; hazard ratio [HR] = 1.57 [95% CI: 1.09–2.26]; p = 0.0146). Median TTD was 13.1 (9.5–19.9) versus 27.6 months (17.3–NE) in patients with versus without TP53mt detected (HR = 1.53 [1.07–2.19]; p = 0.0202) and 20.3 (14.4–NE) versus 11.5 months (7.4–31.1) in patients with v1 versus v3 (HR = 1.29 [0.83–2.01]; p = 0.2641). Patients with TP53mt and v3 had a median TTD of 7.4 months (95% CI: 4.2–31.1).
Conclusion
High ctDNA VAF, EML4-ALK v3, and TP53mt were associated with early discontinuation of first-line ALK TKIs.

Introduction
Stereotactic body radiotherapy (SBRT) has firmly established its role in stage I NSCLC. Clinical trial results may not fully apply to real-world scenarios. This study aimed to uncover the real-world incidence of acute toxicity and 90-day mortality in patients with SBRT-treated stage I NSCLC and develop prediction models for these outcomes.
Methods
Prospective data from the Dutch Lung Cancer Audit for Radiotherapy (DLCA-R) were collected nationally. Patients with stage I NSCLC (cT1-2aN0M0) treated with SBRT in 2017 to 2021 were included. Acute toxicity was assessed, defined as grade greater than or equal to 2 radiation pneumonitis or grade greater than or equal to 3 non-hematologic toxicity less than or equal to 90 days after SBRT. Prediction models for acute toxicity and 90-day mortality were developed and internally validated.
Results
Among 7279 patients, the mean age was 72.5 years, with 21.6% being above 80 years. Most were male (50.7%), had WHO scores 0 to 1 (73.3%), and had cT1a-b tumors (64.6%), predominantly in the upper lobes (65.2%). Acute toxicity was observed in 280 (3.8%) of patients and 90-day mortality in 122 (1.7%). Predictors for acute toxicity included WHO greater than or equal to 2, lower forced expiratory volume in 1 second and diffusion capacity for carbon monoxide, no pathology confirmation, middle or lower lobe tumor location, cT1c-cT2a stage, and higher mean lung dose (c-statistic 0.68). Male sex, WHO greater than or equal to 2, and acute toxicity predicted higher 90-day mortality (c-statistic 0.73).
Conclusions
This nationwide study revealed a low rate of acute toxicity and an acceptable 90-day mortality rate in patients with SBRT-treated stage I NSCLC. Notably, advanced age did not increase acute toxicity or mortality risk. Our predictive models, with satisfactory performance, offer valuable tools for identifying high-risk patients.
简介：立体定向体放射治疗（SBRT立体定向体放射治疗（SBRT）已在 I 期非小细胞肺癌（NSCLC）中发挥了重要作用。临床试验结果可能并不完全适用于实际情况。本研究旨在揭示SBRT治疗的I期NSCLC患者在现实世界中的急性毒性和90天死亡率，并为这些结果建立预测模型：方法：从荷兰肺癌放疗审计（DLCA-R）中收集全国性的前瞻性数据。纳入了2017-2021年接受SBRT治疗的I期NSCLC（cT1-2aN0M0）患者。对急性毒性进行了评估，急性毒性定义为 SBRT 后≤90 天的≥2 级放射性肺炎或≥3 级非血液学毒性。建立了急性毒性和90天死亡率的预测模型，并进行了内部验证：在7279名患者中，平均年龄为72.5岁，21.6%的患者年龄大于80岁。大多数患者为女性（50.7%），WHO评分为0-1分（73.3%），cT1a-b肿瘤（64.6%），主要位于上叶（65.2%）。280名患者（3.8%）出现急性毒性，122名患者（1.7%）90天内死亡。急性毒性的预测因素包括 WHO ≥2、较低的 FEV1 和 DLCO、未经病理确认、中/下叶肿瘤位置、cT1c-cT2a 分期和较高的平均肺剂量（c 统计量为 0.68）。女性性别、WHO ≥2和急性毒性预示着较高的90天死亡率（c统计量为0.73）：这项全国性研究显示，SBRT 治疗的 I 期 NSCLC 患者急性毒性发生率低，90 天死亡率可接受。值得注意的是，高龄并未增加急性毒性或死亡率风险。我们的预测模型性能令人满意，为识别高危患者提供了有价值的工具。
