研究目的:

1. 主要目的: (1) 在手术切除联合影像引导消融治疗的MPLC患者中,基于多组学技术对同一患者的多个空间分离病灶进行DNA+RNA联测,系统刻画多病灶的分子异质性图谱。 (2) 判定多病灶之间的起源关系:区分“独立起源”与“克隆相关”的分子证据链,并形成影像病理对照。 2. 次要目的: (1) 关联临床表型与分子特征:探索多病灶异质性指标(如克隆多样性、共享突变比例、CNV负荷、表达程序差异)与影像学特征(纯GGN/部分实性、CT侵袭征象)、病理分型(AIS/MIA/IA)、以及淋巴结状态/浸润风险之间的关联。 (2) 构建潜在的风险分层指标:初步筛选可用于临床决策的候选生物标志物/特征组合,用于提示“需切除/可消融/可随访”的风险分层(作为探索性结果)。 (3) 比较不同处理方式获得病灶的分子差异:手术切除病灶vs消融/穿刺相关取材病灶在克隆构成与转录状态上的一致性与差异,为“联合策略下取材代表性”提供依据。  

Objectives of Study:

1. Primary Objectives: (1) In MPLC patients undergoing surgical resection combined with image-guided ablation therapy, perform combined DNA+RNA sequencing on multiple spatially separated lesions from the same patient using multi-omics technology to systematically characterize the molecular heterogeneity profile across lesions. (2) Determine the origin relationship between multiple lesions: distinguish molecular evidence chains indicating "independent origin" versus "clonally related," and establish imaging-pathology correlations. 2. Secondary Objectives: (1) Correlate clinical phenotypes with molecular features: Explore associations between multi-lesion heterogeneity metrics (e.g., clonal diversity, shared mutation ratio, CNV burden, expression program differences) and imaging characteristics (pure GGN/part-solid, CT invasive signs), pathological subtypes (AIS/MIA/IA), as well as lymph node status/invasion risk. (2) Develop potential risk stratification indicators: Preliminary screening of candidate biomarkers/feature combinations for clinical decision-making to suggest risk stratification ("requires resection/eligible for ablation/can be monitored," as exploratory findings). (3) Compare molecular differences between lesions obtained via different approaches: Assess consistency and divergence in clonal composition and transcriptional states between surgically resected lesions vs. ablation/biopsy-derived samples, providing evidence for "sample representativeness under combined strategies."
