研究目的:

本项目为一项多中心的回顾性研究,旨在探讨和验证基于新辅助治疗前、后增强CT构建的两种影像组学模型对局部进展期胃癌患者的新辅助治疗反应性及治疗后能否达到病理完全缓解的预测价值。  

Objectives of Study:

This project is a multicenter retrospective study aimed at investigating and validating the predictive value of two imaging radiomics models constructed based on contrast-enhanced computed tomography (before and after neoadjuvant therapy) for predicting the treatment response and achieving pathological complete response in patients with locally advanced gastric cancer following neoadjuvant therapy.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.治疗前经组织病理学或细胞学证实的胃腺癌,并通过影像学检查(增强CT/超声造影)确定为可手术切除的无远处转移的局部晚期胃癌(cT3-4,N0/+,M0,分期标准参照第八版AJCC指南); 2.新辅助治疗前、新辅助治疗后(手术前),均接受腹部增强CT检查; 3.接受新辅助治疗(单纯化疗或化疗联合免疫治疗)后,行胃癌根治术,术后病理证实肿瘤反应; 4.临床、病理[必须含术后肿瘤退缩分级(TRG)]随访资料完整。

Inclusion criteria

1. Histologically or cytologically confirmed gastric adenocarcinoma prior to treatment, with imaging studies (contrast-enhanced CT/contrast-enhanced ultrasonography) confirming resectable locally advanced gastric cancer without distant metastasis (cT3-4, N0/+, M0; staging according to the 8th edition AJCC guidelines); 2. Abdominal contrast-enhanced CT scans performed both before neoadjuvant therapy and after neoadjuvant therapy (prior to surgery); 3. Underwent radical gastrectomy following neoadjuvant therapy (chemotherapy alone or chemotherapy combined with immunotherapy), with postoperative pathological confirmation of tumor response; 4. Complete clinical and pathological follow-up data [including essential postoperative tumor regression grade (TRG) assessment].

排除标准:

1.既往有胃部手术史; 2.新辅助治疗前有胃癌和其他肿瘤病史及相关治疗史; 3.多发性胃癌(含两处及两处以上的病灶); 4.增强CT图像上无法检出原发病灶; 5.CT图像质量欠佳(伪影严重、胃充盈差)。

Exclusion criteria:

1. Previous history of gastric surgery; 2. Prior to neoadjuvant therapy, the patient had a history of gastric cancer or other tumors with documented antitumor treatment; 3. Multiple gastric cancer (including two or more lesions); 4. The primary lesion could not be detected on enhanced CT images; 5. CT image quality is poor (serious artifact, poor gastric filling).
