Study design:

Cohort study 

研究目的:

评估手术切缘宽度(宽切缘>1cm 对比 窄切缘≤1cm)对复发性肝细胞癌(HCC)患者再次肝切除术后总生存时间(OS)和术后再复发的影响,并进一步探讨基于术前微血管侵犯(MVI)预测风险下切缘对预后的影响。  

Objectives of Study:

To evaluate the impact of surgical margin (wide margin >1 cm vs. narrow margin ≤1 cm) on overall survival (OS) and postoperative recurrence in patients with recurrent hepatocellular carcinoma (HCC) undergoing repeat hepatectomy, and to further investigate the prognostic effect of surgical margin under the risk stratification based on preoperative microvascular invasion (MVI).

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. 年龄 18-75 岁; 2. 首次 HCC 行根治性切除术后复发,接受再次肝切除术,病理确诊为 HCC; 3. 病历资料能够使用术前使用 nomogram 模型评估 MVI 风险; 4. 手术切缘宽度有明确病理记录; 5. 病历资料完整(包括基线特征、手术记录、随访数据)。

Inclusion criteria

1. Aged 18–75 years; 2. Recurrence after radical resection for primary hepatocellular carcinoma (HCC), underwent repeat hepatectomy with a pathological confirmation of HCC; 3. Medical records available to allow preoperative assessment of MVI risk using a nomogram model; 4. The width of the surgical margin was clearly documented in the pathological report; 5. Complete medical records were available (including baseline characteristics, operative records, and follow-up data).

排除标准:

1. 首次手术为非根治性切除; 2. 首发手术后在 1 年内确诊肿瘤复发; 3. 复发肿瘤为多发、肿瘤直径>5cm,肿瘤位置邻近重要解剖结构导致手术困难; 4. 首发及复发肿瘤存在肝外转移及主要门静脉、肝静脉、胆管癌栓; 5. 复发手术前提示肝功能差于 Child A 级; 6. 再次手术前接受过系统抗肿瘤治疗(如 TACE 或其他介入治疗、靶向治疗、免疫治疗); 7. 合并其他恶性肿瘤; 8. 病历缺失关键信息(如切缘宽度、MVI 风险评分、随访数据)。

Exclusion criteria:

1. The first hepatectomy was non?radical resection. 2. Tumor recurrence was diagnosed within 1 year after primary surgery. 3. Recurrent tumors were multiple, with a diameter > 5 cm, or located adjacent to vital anatomical structures, resulting in surgical difficulty. 4. Extrahepatic metastasis and tumor thrombus in the main portal vein, hepatic vein, or bile duct were present in both primary and recurrent tumors. 5. Liver function was worse than Child?Pugh Class A before repeat hepatectomy. 6. Received systemic anti?tumor therapy prior to re-hepatectomy (e.g., TACE or other interventional therapy, targeted therapy, immunotherapy). 7. Complicated with other malignant tumors. 8. Missing key information in medical records (e.g., surgical margin width, MVI risk score, follow?up data).
