About this trial

This is an interventional treatment trial for Colorectal Neoplasms focused on measuring Microwave ablation, Ablation techniques, Operative surgical procedures, Hepatic resection, Surgery, Outcomes assessment

Eligibility Criteria

18 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Diagnosis of adenocarcinoma of the colon or rectum (diagnosed at the time of colon or rectal resection or on endoscopic biopsy) with liver metastases (by liver biopsy or by history of biopsy-proven colon/rectal cancer with characteristic imaging findings):
  • Imaging showing typical features of colorectal cancer liver metastasis;
  • Cytologic/histologic diagnosis of colorectal cancer or colorectal cancer liver metastasis.
  • No more than 3 hepatic metastatic lesions noted on preoperative imaging
  • No lesion greater than 5 cm in maximal dimension
  • Adequate clinical condition to undergo laparoscopic or robot-assisted laparoscopic liver resection or microwave ablation as treatment for colorectal cancer liver metastases
  • Willing and able to give informed consent

Exclusion Criteria:

  • Radiologic (computed tomography or magnetic resonance imaging) evidence of invasion into major portal/hepatic venous branches and no extrahepatic metastases
  • Evidence of recurrent disease adjacent to a previous ablation or resection site
  • Severe renal dysfunction (creatinine clearance of <40 mL/min)
  • Pregnant or nursing women

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

Microwave ablation

Hepatic resection

Arm Description

Patients will be given general anesthesia. A laparoscopic trocar and additional ports will be placed under direct visualization and pneumoperitoneum will be established. Once the operating surgeon determines that the lesions as evaluated on intraoperative ultrasound remain amenable to MWA, ablations will be performed with a 2.45-gigahertz (GHz) generator with a 1.8-mm-diameter transcutaneous antenna (Acculis pMTA Accu2i; AngioDynamics Inc., Denmead, Hampshire, UK). Additional ablations will be performed sequentially. Laparoscopic core needle biopsy of lesions will be performed and submitted for permanent pathologic sectioning per current treatment standards. At the conclusion of the ablation, a collapsed titanium clip will be inserted into the microwave antenna tract as a radiographic fiducial marker. Hemostasis of the ablation track will be ensured using a combination of microwave energy, monopolar electrocautery, and/or topical hemostatics.

General anesthesia will be induced. A laparoscopic trocar and additional ports will be placed under direct visualization and pneumoperitoneum will be established. The liver will be evaluated with intraoperative ultrasound (BK Medical A/S, Herlev, Denmark). Laparoscopic core needle biopsy of lesions will be performed. Partial hepatectomy may be carried out with parenchymal precoagulation with radiofrequency electrosurgical devices such as the LigaSure™ (Covidien, Medtronic; Minneapolis, MN), Harmonic® (Ethicon Endosurgery; Cincinnati, OH), or saline-coupled radiofrequency ablation device (Aquamantys™; Covidien/Medtronic; Minneapolis, MN); hepatic parenchymal transection can be performed as above or with the use of stapling devices to ligate and divide parenchyma. Hepatic vascular inflow occlusion will be performed at the surgeon's discretion. A topical hemostatic may be used along the transected hepatic parenchyma. Resected specimens will be preserved in formalin for pathology.

Outcomes

Primary Outcome Measures

Local disease control at the site of intervention
Local disease control is measured from time of randomization and is defined as the absence of local recurrence of metastatic adenocarcinoma of the colon or rectum as determined by diagnostic imaging.

Secondary Outcome Measures

Overall survival
Intrahepatic disease-free survival
Postoperative morbidity
Postoperative mortality

5. Study Description

Brief Summary
This single-center, prospective, randomized clinical trial is designed to compare the clinical characteristics and outcomes of hepatic resection and microwave ablation (MWA) to determine the optimal operative intervention for the local treatment of resectable colorectal cancer liver metastases. The primary aim of this study is to test the following hypothesis: 2-year local disease control is equivalent between patients receiving the experimental therapy (MWA) and patients receiving the standard therapy (hepatic resection) as treatment for colorectal cancer liver metastases determined to be resectable by radiographic imaging. Secondarily, the investigators expect that 2-year intrahepatic (regional) and metastatic disease recurrence rates are equivalent between the two treatment arms in this study.
