Diagnostic test for accuracy 

研究目的:

1. 主要研究目的:以术后病理分期(pTNM,重点为pT与pN)为金标准,比较AI模型与临床医生术前分期在pT分期及pN分期预测的总体准确率(Accuracy)差异。 2. 次要研究目的: (1)分别计算并比较AI模型与医生在关键临床任务中的诊断效能指标:敏感度(Sensitivity)、特异度(Specificity)、阳性预测值(PPV)、阴性预测值(NPV)、F1值及ROC曲线下面积(AUC),重点包括T1/T2与T3/T4的区分、N0与N+的区分。 (2)评估AI cTNM分期、医生cTNM与金标准pTNM之间的一致性(加权Kappa)。 (3)探索不同亚组(如肿瘤部位:贲门/胃体/胃窦;分化程度:高/中/低分化等)中AI模型性能的稳定性与差异。 (4)评估AI模型输出的可用性指标(如推理时间、失败率/不可评估率及其原因)。  

Objectives of Study:

1. Main research objective: Using postoperative pathological staging (pTNM, with a focus on pT and pN) as the gold standard, compare the overall accuracy (Accuracy) differences between the AI model and the clinicians' preoperative staging in predicting pT stage and pN stage. 2. Secondary research objectives: (1) Calculate and compare the diagnostic efficacy indicators of the AI model and the doctors in key clinical tasks: sensitivity (Sensitivity), specificity (Specificity), positive predictive value (PPV), negative predictive value (NPV), F1 value, and the area under the ROC curve (AUC), with a focus on the distinction between T1/T2 and T3/T4, and between N0 and N+. (2) Evaluate the consistency (weighted Kappa) between the AI cTNM staging, the doctors' cTNM, and the gold standard pTNM. (3) Explore the stability and differences in the performance of the AI model in different subgroups (such as tumor location: cardia/gastric body/gastric antrum; differentiation degree: high/middle/low differentiation, etc.). (4) Evaluate the usability indicators of the AI model output (such as inference time, failure rate/undetectable rate, and the reasons for it).

纳入标准:

1. 年龄/性别:18-80岁,性别不限。 2. 诊断:经胃镜活检病理确诊为胃腺癌。 3. 治疗计划:经多学科讨论(MDT)评估,拟行根治性胃切除术并计划行D2淋巴结清扫(拟定手术方式由临床团队按常规决定)。 4. 检查与时间窗:在根治手术前完成本中心常规流程的增强CT与胃镜检查,且满足以下要求: (1)影像检查至手术时间窗:≤14天(如因临床原因超过时间窗,须记录原因,可纳入描述性/敏感性分析); (2)CT包含至少门静脉期(如本中心常规含动脉期/平衡期则按常规记录相位); (3)胃镜图像/视频在院内系统可追溯、可导出用于研究分析。 5. 图像可用性(最低质量要求): (1)CT无严重运动伪影、对比剂注射失败或关键相位缺失; (2)胃镜图像无严重模糊/过度出血遮挡导致病灶不可判读; (3)影像质量由研究预设的质控标准判定“可评估”: (4)合格CT与胃镜影像; (5)AI成功输出并锁定; (6)医生完成cTNM记录; (7)完成根治切除且获得完整病理pT/pN。 6. 伦理要求:受试者本人或法定代理人签署知情同意书,愿意配合研究流程及数据使用。

Inclusion criteria

1. Age/Gender: 18 - 80 years old, gender not restricted. 2. Diagnosis: Confirmed as gastric adenocarcinoma through gastroscopy biopsy and pathological examination. 3. Treatment plan: After multidisciplinary discussion (MDT), a radical gastrectomy is planned, and D2 lymph node dissection is scheduled (the specific surgical method will be determined by the clinical team according to routine procedures). 4. Examination and time window: Before the radical surgery, complete the routine procedures of enhanced CT and gastroscopy at this center, and meet the following requirements: (1) Time window from imaging examination to surgery: <= 14 days (if the time window is exceeded due to clinical reasons, the reason must be recorded and can be included in descriptive/sensitivity analysis); (2) CT includes at least the portal venous phase (if the center's routine includes arterial phase/balanced phase, record the phase as usual); (3) Gastroscopy images/videos can be traced and exported in the hospital system for research analysis. 5. Image availability (minimum quality requirements): (1) CT has no severe motion artifacts, contrast agent injection failure, or missing key phases; (2) Gastroscopy images have no severe blurriness/overly bleeding that obscures the lesion and makes it impossible to interpret; (3) Image quality is judged as "assessable" by the research-predefined quality control standards: (4) Qualified CT and gastroscopy images; (5) AI successfully outputs and locks; (6) Doctors complete cTNM records; (7) Radical resection is completed and complete pathological pT/pN are obtained. 6. Ethical requirements: The subject or their legal representative signs the informed consent form and is willing to cooperate with the research process and data usage.

排除标准:

1. 既往抗肿瘤治疗:术前接受过针对本次胃癌的新辅助化疗、放疗、免疫治疗或靶向治疗者。 2. 既往胃部手术史:既往行胃切除、胃旁路或其他显著改变胃部解剖结构的手术(可能影响影像解剖与AI识别)。 3. 合并其他恶性肿瘤:同时合并其他活动性恶性肿瘤,或既往恶性肿瘤在近5年内复发/转移。 4. 无法完成根治性切除:术中发现远处转移或腹膜广泛播散等原因导致无法行根治性切除者(此类病例一般无法获得可比的“根治术后pTNM”,将作为筛除/不可评估处理)。 5. 关键数据缺失或参考标准不可判定:术后病理资料不完整,无法明确pT或pN(或无法按预设标准形成pTNM);或关键淋巴结信息缺失导致分期无法判定。 6. 影像资料不可用/不可评估: (1)术前CT或胃镜影像无法获取、丢失或去标识化失败; (2)影像质量严重不合格,按预设质控标准判定为“不可评估”。 7. 其他研究者认为不适宜入组情况:如存在影响依从性或数据完整性的情况。

Exclusion criteria:

1. Previous anti-tumor treatment: Those who received neoadjuvant chemotherapy, radiotherapy, immunotherapy or targeted therapy for this gastric cancer before the surgery. 2. Previous history of gastric surgery: Those who had undergone gastric resection, gastric bypass or other surgeries that significantly altered the anatomical structure of the stomach (which may affect imaging anatomy and AI recognition). 3. Coexisting other malignant tumors: Those who had concurrent active malignant tumors, or whose previous malignant tumors had recurred or metastasized within the past 5 years. 4. Unable to undergo radical resection: Those who were unable to undergo radical resection due to distant metastasis or extensive peritoneal dissemination discovered during the surgery (such cases generally cannot obtain comparable "post-radical resection pTNM" and will be treated as screening exclusion or unassessable). 5. Missing key data or unidentifiable reference standards: Postoperative pathological data is incomplete, making it impossible to determine pT or pN (or unable to form pTNM according to the preset standards); or key lymph node information is missing, resulting in the inability to determine the stage. 6. Unavailable or unassessable imaging data: (1) Preoperative CT or gastroscopy images cannot be obtained, lost, or failed to be de-identified; (2) The imaging quality is severely substandard, and is judged as "unassessable" according to the preset quality control standards. 7. Other situations considered inappropriate for inclusion by the researchers: Such as situations that affect compliance or data integrity.
