Details and patient eligibility

About

HARVEST is an investigator-initiated prospective randomized controlled study comparing adjuvant intravenous systemic chemotherapy with or without HAI- floxuridine (FUDR) in CRC patients post-liver metastasectomy.

Full description

Numerous retrospective studies have indicated a positive synergistic effect of combining adjuvant oxaliplatin/irinotecan-based doublet systemic chemotherapy and hepatic arterial infusion (HAI) for colorectal cancer (CRC) patients following colorectal cancer liver metastases (CRLM) resection. However, this strategy has not been evaluated prospectively to date. HARVEST is an investigator-initiated prospective randomized controlled study comparing adjuvant intravenous systemic chemotherapy with or without HAI- floxuridine (FUDR) in CRC patients post-liver metastasectomy.

Enrollment: 92 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. The primary lesion has undergone or is capable of radical resection, and liver metastases can undergo R0/R1 resection (including intraoperative interventional ablation therapy), and postoperative achievement of no evidence of disease (NED).
2. Histologically confirmed colorectal adenocarcinoma
3. Radiologically or pathologically confirmed diagnosis of colorectal liver metastasis
4. No previous surgery, interventional ablation, hepatic arterial infusion (HAI), radiotherapy, or transarterial chemoembolization (TACE) for liver metastases.
5. CT, MRI, or PET/CT (if necessary) confirmed no extrahepatic metastasis.
6. Normal hematologic function (platelets > 90×10^9/L; white blood cells > 3×10^9/L; neutrophils > 1.5×10^9/L).
7. No ascites, normal coagulation function, albumin ≥ 35g/L.
8. Liver function graded as Child-Pugh class A.
9. Serum bilirubin ≤ 1.5 times the upper limit of normal (ULN), transaminases ≤ 5 times ULN, alkaline phosphatase ≤ 2.5 ULN.
10. Serum creatinine below the upper limit of normal (ULN), or calculated creatinine clearance > 50ml/min (using Cockcroft-Gault formula).
11. ECOG performance status of 0-2
12. Life expectancy ≥ 3 months
13. Patients have provided a signed Informed Consent Form
14. Willing and able to undergo follow-up until death or the end of the study or study termination.

Exclusion criteria

1. Have had any extrahepatic metastasis after being diagnosed with colorectal cancer.
2. Previous surgery, interventional ablation, hepatic arterial infusion (HAI), radiotherapy, or transarterial chemoembolization (TACE) for liver metastases.
3. Liver metastases intended for interventional ablation treatment only.
4. Presence of hepatic artery vascular variation identified by CTA examination, making HAI implantation unsuitable.
5. Severe arterial embolism or ascites.
6. Bleeding tendency or coagulation disorders.
7. Hypertensive crisis or hypertensive encephalopathy.
8. Severe uncontrollable systemic complications such as infection or diabetes.
9. Clinically significant cardiovascular diseases such as cerebrovascular accidents (in the last 6 months before enrollment), myocardial infarction (in the last 6 months before enrollment), uncontrolled hypertension despite appropriate drug treatment, unstable angina, congestive heart failure (NYHA 2-4), and arrhythmias requiring medication.
10. History of or physical examination indicating central nervous system diseases (such as primary brain tumors, uncontrollable epilepsy, any brain metastasis, or history of stroke).
11. Had any other malignant tumors in the past 5 years (excluding basal cell carcinoma and/or cervical carcinoma in situ after radical surgery).
12. Received any investigational drug treatment in the last 28 days before the study.
13. Any residual toxicity from previous chemotherapy (excluding alopecia), such as peripheral neuropathy ≥ NCI CTC v3.0 grade 2, makes the use of a treatment regimen containing oxaliplatin not considered.
14. Allergic to any drugs in the study.
15. Pregnant or lactating women who are not using or refuse to use effective non-hormonal contraception (intrauterine device, barrier contraception combined with spermicidal gel, or sterilization) in women of childbearing age (last menstrual period < 2 years ago) or fertile men who cannot or do not wish to comply with the study protocol.
16. Presence of any other diseases, functional impairment due to metastatic lesions, or suspicious findings in the physical examination suggesting contraindications to the use of the investigational drug or placing the patient at a high risk of treatment-related complications.

92 participants in 2 patient groups

HAI group

Experimental group

Description:

Patients will receive systemic chemotherapy on days 1 and 15 using either of the following regimens: mFOLFOX6 (Oxaliplatin 85 mg/m2; Leucovorin 200mg/m2; followed by an infusion of 5-fluorouracil 2.4 g/m2 administered over 46 hours) or mFOLFIRI (Irinotecan 180mg/m2; Leucovorin 200mg/m2; followed by an infusion of 5-fluorouracil 2.4 g/m2 administered over 46 hours) For HAI, FUDR was administered as a continuous infusion of 0.12 mg/kg/day over 14 days via the HAI pump, along with dexamethasone 20 mg, and normal saline was used to fill up the 300ml pump reservoir.
