研究目的:

1主要目的 系统描述女性甲状腺癌与乳腺癌双原发患者的临床病理特征及分子表型分布,并基于真实世界数据构建和验证一个可预测第二原发癌发生风险的预测模型。 2 次要目的 1) 比较双原发癌患者与单癌(仅甲状腺癌或仅乳腺癌)患者在人口学、肿瘤特征及治疗模式上的差异; 2) 探索与第二原发癌发生显著相关的独立危险因素,包括临床变量(如初诊年龄、放疗史)及分子标志物(如乳腺癌ER/PR/HER2状态、甲状腺癌BRAF/RAS突变状态); 3) 评估双原发癌状态对患者无病生存期(DFS)和总生存期(OS)的影响; 4) 通过敏感性分析,比较同时性(<=6个月)与异时性(>6个月)双原发癌患者的特征差异。  

Objectives of Study:

1 Primary Objective To describe the clinicopathological characteristics and molecular phenotype distribution of female patients with double primary cancers of thyroid cancer and breast cancer, and to construct and validate a predictive model based on real-world data for estimating the risk of developing a second primary cancer. 2 Secondary Objectives 1) To compare the differences in demographics, tumor characteristics, and treatment patterns between patients with double primary cancers and those with single cancers (thyroid cancer only or breast cancer only); 2) To explore independent risk factors significantly associated with the occurrence of a second primary cancer, including clinical variables (such as age at initial diagnosis, history of radiotherapy) and molecular markers (such as breast cancer ER/PR/HER2 status, thyroid cancer BRAF/RAS mutation status); 3) To assess the impact of double primary cancer status on patients' disease-free survival (DFS) and overall survival (OS); 4) To compare the characteristic differences between patients with synchronous (<=6 months) and metachronous (>6 months) double primary cancers through sensitivity analysis.

纳入标准:

Inclusion criteria

排除标准:

真实世界队列: 1. 诊断时已存在远处转移(M1 期) 2. 第二肿瘤为良性病变、原位癌(如 DCIS、甲状腺微小乳头状癌未达浸润标准)或转移性癌 3. 关键变量缺失率 >30%(如无病理类型、无随访记录) 4. 同时患有除甲状腺癌和乳腺癌外的第三原发恶性肿瘤(避免混杂) SEER队列: 1. 任一肿瘤被标记为“仅尸检发现”或“诊断来源不可靠” 2. 缺失关键协变量(如年龄、种族、分期、组织学类型)且无法通过 SEER 衍生变量合理填补 3. 第二原发癌发生在首癌诊断前(逻辑错误) 4. 数据来自非基于人群的注册子库(如仅限特定医院的子集),以保障代表性

Exclusion criteria:

Real-world cohort: 1. Distant metastasis (M1 stage) present at diagnosis 2. Second tumor is a benign lesion, carcinoma in situ (e.g., DCIS, thyroid micro-papillary carcinoma not meeting invasive criteria), or metastatic cancer 3. Missing rate of key variables >30% (e.g., no pathological type, no follow-up records) 4. Concurrent third primary malignancy other than thyroid cancer and breast cancer (to avoid confounding) SEER cohort: 1. Either tumor marked as "autopsy only" or "diagnosis source unreliable" 2. Missing key covariates (e.g., age, race, stage, histological type) that cannot be reasonably imputed via SEER derived variables 3. Second primary cancer occurred before index cancer diagnosis (logical error) 4. Data from non-population-based registry sub-collections (e.g., subset limited to specific hospitals) to ensure representativeness
