研究目的: |
加强局部和全身治疗,以提高完全缓解率(病理完全缓解或持续临床完全缓解≥2年),从而提高器官保存的机会,减少局部复发,为需要行腹会阴切除的低位直肠癌患者提供生存益处。 |

Objectives of Study: |
The purpose of this study is to intensify local and systemic treatment to increase the rate of complete response (CR; pCR or sustained cCR≥2 years), leading to improve the chance of organ preservation and reduce local regrowth, and provide potential survival benefit for distal LARC patients who are amenable to abdominoperineal resection. |

药物成份或治疗方案详述: |
1、动脉灌注化疗: 使用Seldinger方法进行股动脉穿刺和导管插入术。根据血管造影,对直肠上动脉和双侧髂内动脉进行超选择性插管,并通过导管给予化疗药物。伊立替康130 mg/m2,雷替曲塞2mg/m2,奥沙利铂70 mg/m2注射到直肠上动脉和双侧髂内动脉(比例约为4:3:3),然后将溶于2-3ml超液体碘油的0.5mg雷替曲赛通过直肠上动脉输注到肿瘤的主要供血血管。碘油被用作抗癌药物的载体,而不是栓塞。 2、放化疗: 完成动脉灌注化疗2周后,患者开始放化疗。放化疗包括5周行25次每次2Gy总共50Gy放疗,同时在放疗日每天两次口服卡培他滨825mg/m2。 3、巩固化疗: 在完成放化疗3周后,使用6个周期改良FOLFIRINOX巩固化疗(奥沙利铂85 mg/m2,2小时静脉输注,随后伊立替康160 mg/m2, 90分钟静脉输注,然后亚叶酸400 mg/m2静脉输注2小时,氟尿嘧啶2600 mg/m2连续静脉输注48小时,一个化疗周期为2周)。 4、评估: 完成放化疗和四个巩固化疗周期后进行两次中期评估(包括盆腔MRI及胸腹部CT)。出现远处转移或肿瘤进展的患者将被不再进行原研究方案治疗,并根据病情接受适当的治疗。巩固化疗完成后4周进行最终评估,包括直肠指检、癌胚抗原(CEA)、骨盆MRI、胸部和腹部CT、内镜(活检)。根据Maas设定的标准,肿瘤反应分为完全缓解或不完全缓解。建议对完全缓解的患者进行选择性等待观察,并进行密切监测。他们也可以自行决定接受手术。不完全缓解患者必须接受手术,对于具有不良病理特征(阳性切除边缘,神经/淋巴/血管侵犯、肿瘤沉积、或淋巴结转移)的患者,建议使用六个周期的mFOLFOX6术后辅助化疗。 5、随访: 对完全缓解行等待观察的患者,前2年每3个月进行一次直肠指检、CEA和乙状结肠镜检查,后3年每6个月进行1次。直肠MRI前2年每6个月进行一次,后3年每年进行一次。每年至少对胸部和腹部进行一次CT扫描。如有必要,将更频繁地对患者进行评估。放射学、内镜和体格检查中发现的任何肿瘤再生迹象都是挽救手术的指征。如果患者拒绝直肠全系膜切除术,也可进行局部切除术。手术患者将根据现行指南进行随访。 |

Description for medicine or protocol of treatment in detail: |
1 Intra-arterial chemotherapy: Irinotecan 130 mg/m2, followed by raltitrexed 2mg/ m2 then oxaliplatin 70 mg/m2 is administered to superior rectal artery and bilateral internal iliac arteries (the ratio is approximately 4:3:3), then 0.5 mg raltitrexed dissolved in 2-3ml lipiodol ultra-fluid is infused to the main feeding vessels to the neoplastic lesion through superior rectal artery. In this setting, lipiodol ultra-fluid is used as a carrier of anticancer drugs, not for embolization. Femoral artery puncture and catheterization is performed using the Seldinger approach. According to the angiogram, super selective catheterization of superior rectal artery and bilateral internal iliac arteries is performed and chemotherapy drugs are administered via the catheter. 2 Chemoradiotherapy: On completion of 2 weeks of intra-arterial chemotherapy, patients begin chemoradiotherapy. chemoradiotherapy consisted of 50 Gy in 25 fractions over 5 weeks, concurrently with capecitabine 825mg/m2 twice daily on radiotherapy days. 3 Consolidation chemotherapy: On completion of 3 weeks of chemoradiotherapy, six cycles of modified FOLFIRINOX consolidation chemotherapy (oxaliplatin 85 mg/m2 delivered as a 2-h intravenous infusion, followed by irinotecan160 mg/m2 as a 90-min intravenous infusion, then leucovorin 400 mg/m2 delivered as a 2-h intravenous infusion, and fluorouracil 2600 mg/m2 by continuous intravenous infusion over 48 h every 2 weeks) is used. 4 Response assessment: Twice interim evaluations will be performed with a pelvic MRI and a chest and abdomen CT after chemoradiotherapy and four cycles of consolidation chemotherapy.Patients who develop distant metastasis or tumor progression will be removed from the study protocol and receive proper treatment. Final evaluation will be performed 4 weeks after completion of consolidation chemotherapy, including digital rectal examination, carcinoembryonic antigen (CEA), pelvis MRI, chest and abdomen CT, endoscopy (with biopsy). Tumor response is graded as clinical complete response or noncomplete response, and clinical complete response is defined according to the criteria set by Maas et al.Patients with clinical complete response will be recommended for Watch and Wait observation with close surveillance. They could also undergo surgery at their own discretion. Patients with noncomplete response will be referred for immediate surgery. Adjuvant chemotherapy with six cycles of mFOLFOX6 will be used for patients with adverse pathological features (positive circumferential resection margin, tumors deposits, perineural/lymphatic/vascular invasion, and lymph node metastases). 5 Post-treatment surveillance: For patients with initial cCR, digital rectal examination, CEA and sigmoidoscopy are to be performed every 3 months for the first 2 years, and every 6 months for the following 3 years. Rectal MRI is to be performed every 6 months for the first 2 years and yearly for the following 3 years. CT scans of the chest and abdomen at least once a year. Patients will be evaluated more frequently if necessary. Any evidence of tumor regrowth on radiologic, endoscopic and physical examination are indication for salvage TME surgery. If patients refuse TME, local resection will also be acceptable. Patients undertaken TME will be surveyed according to current guidelines. |
