Neoadjuvant chemotherapy, particularly chronomodulated oxaliplatin and 5-Fluorouracil/folinic acid, can improve outcomes for patients with initially unresectable colorectal liver metastases, potentially enabling curative surgery.

Area of Science:

  • Hepatobiliary Surgery
  • Medical Oncology
  • Gastrointestinal Oncology

Context:

  • Complete tumor resection is the only curative option for colorectal liver metastases.
  • Hepatic resection is often not feasible due to tumor size, multiplicity, or proximity to vessels.

Purpose:

  • To evaluate the efficacy of neoadjuvant chemotherapy in downstaging unresectable colorectal liver metastases.
  • To assess the potential for secondary curative resection after chemotherapy.

Summary:

  • Fluorouracil (5-Fu) alone shows poor response rates (10-20%).
  • Regional chemotherapy yields higher response rates (40-50%) but is invasive.
  • Newer combination chemotherapies (irinotecan or oxaliplatin with 5-Fu/FA) achieve 50% response rates.
  • Chronomodulated chemotherapy with oxaliplatin and 5-Fu/FA shows promise in neoadjuvant settings.

Impact:

  • Antitumor activity translates to long-term survival benefits.
  • Multidisciplinary approaches can potentially cure patients with initially unresectable disease.
  • Increased cure rates for metastatic colorectal cancer are anticipated with collaborative care.
