研究目的: |
评估不同维持治疗方案(包括单纯化疗、化疗联合靶向、单药靶向或联合免疫等)在pMMR/MSS型结直肠癌伴肝和/或肺转移患者中的无进展生存期(progression-free survival, PFS)。 |
||||||||||||||||||||||
|
Objectives of Study: |
To evaluate progression-free survival (PFS) among patients with proficient mismatch repair/microsatellite stable (pMMR/MSS) colorectal cancer and synchronous or metachronous liver and/or lung metastases, comparing the following maintenance treatment regimens: chemotherapy alone, chemotherapy combined with targeted therapy, single-agent targeted therapy, and immunotherapy-based combinations. |

纳入标准: |
1.年龄≥18岁,性别不限; 2.经组织病理学确诊的结直肠腺癌; 3.经免疫组化(immunohistochemistry, IHC)和/或PCR(polymerase chain reaction)检测确认为pMMR/MSS型; 4.影像学证实存在肝和/或肺转移(初始不可切除或转化治疗后); 5.已完成≥4个月的一线诱导治疗(化疗±靶向治疗)且达到疾病控制(stable disease, SD/partial response, PR/complete response, CR); 6.接受≥2个月的维持治疗(包括但不限于氟尿嘧啶类单药/联合靶向、免疫检查点抑制剂、抗血管生成药物等); 7.具有完整的基线资料和随访记录。 |

Inclusion criteria |
1. Age >= 18 years; no restrictions on sex or gender; 2. Histopathologically confirmed colorectal adenocarcinoma; 3. Proficient mismatch repair/microsatellite stable (pMMR/MSS) status confirmed by immunohistochemistry (IHC) and/or polymerase chain reaction (PCR); 4. Radiologically confirmed liver and/or lung metastases—either initially unresectable or rendered resectable following conversion therapy; 5. Completion of >= 4 months of first-line induction therapy (chemotherapy with or without targeted agents), achieving disease control defined as stable disease (SD), partial response (PR), or complete response (CR) per RECIST v1.1 criteria; 6. Receipt of >= 2 months of maintenance therapy, including fluoropyrimidine-based regimens (monotherapy or combined with targeted agents), immune checkpoint inhibitors, or anti-angiogenic agents; 7. Availability of complete baseline clinical, imaging, and laboratory data, as well as longitudinal follow-up records sufficient for progression-free survival (PFS) assessment. |
||||||||||||||||||||||
|
排除标准: |
1.MSI-H/dMMR型结直肠癌; 2.合并其他活动性恶性肿瘤(非黑色素瘤皮肤癌除外); 3.存在脑膜转移或活动性脑转移; 4.维持治疗期间接受局部治疗(如手术、射频消融、放疗等); 5.临床资料不完整或失访; 6.维持治疗期间因非疾病进展原因中断治疗>2个月。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Microsatellite instability–high (MSI-H) or mismatch repair–deficient (dMMR) colorectal cancer; 2. Concurrent active malignancy other than non-melanoma skin cancer; 3. Leptomeningeal carcinomatosis or radiologically confirmed active brain metastases; 4. Receipt of locoregional interventions—including surgery, radiofrequency ablation, or radiotherapy—during the maintenance therapy period; 5. Incomplete baseline clinical, imaging, or laboratory data, or loss to follow-up prior to primary endpoint assessment; 6. Treatment interruption exceeding two months during maintenance therapy for reasons unrelated to disease progression. |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data entry personnel familiar with the project background, input training. Data checkers focus on data value ranges, verification of outliers, logical relationships between variables, missing data, and key dates and times. Informed consent has been signed in the surgical informed consent of patients before radical surgical operation and is archived in the medical record room along with the medical record documents. |
