  Purpose

Is a perioperative chemotherapy based on FOLFOX and Cetuximab (K-RAS wild-type) associated with a higher rate of postoperative complications in patients with resectable colorectal liver metastases as compared to only adjuvant FOLFOX and chemotherapy? Are there any differences for disease free survival between periand postoperative treatment in patients with >3 liver metastases or at least one metastasis > or = 5 cm in diameter?

Primary Outcome Measures:
  • Clavien score (> grade 1) [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
    The first primary objective of the study is to compare the postoperative complication rate according to Clavien score (> grade 1) of a perioperative chemotherapy with a postoperative regimen

  • Disease free survival [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    A second primary objective of the study is to compare for the patient subgroup with >3 liver metastases or at least one metastasis > or = 5 cm in diameter the median disease free survival.


Secondary Outcome Measures:
  • Secondary objectives [ Time Frame: 5 years ] [ Designated as safety issue: Yes ]

    Secondary Objectives:

    • To compare the overall disease-free survival.
    • To compare the overall survival.
    • To compare operation, resection and R0 rates.
    • To compare the safety and chemotherapy-associated toxicity (NCI-CTC V4.0)
    • To compare the effect of a perioperative therapy on healthrelated quality of life (EORTC QLQ-C30 + QLQ-LMC21).
    • To compare the number of cycles, dose intensity and dose modifications applied.
    • To evaluate the response rate (RECIST V1.1 no confirmation of response needed) after preoperative chemotherapy.
    • Resected liver mass

Detailed Description:

In recent years chemotherapy based on FOLFOX and cetuximab has become a standard treatment in patients with colorectal liver metastases. Recently, the analysis of the CELIM trial reported response rates of 70% in patients with initially unresectable colorectal liver metastases treated with FOLFOX + Cetuximab. 46% of the patients had their metastases R0 or R1 resected or a ablation by radiofrequency with an overall 34% R0 resection rate. In recent studies, adjuvant chemotherapy with FOLFOX leads to a prolongation of disease free survival after successful resection of colorectal liver metastases, but there is not sufficient data concerning a perioperative regimen. In only one study of Nordlinger et al. a trend in progression-free survival could be reached in patients receiving a perioperative FOLFOX-therapy, but without reaching statistical significance. Furthermore those patients displayed a significantly higher rate of postoperative complications and morbidity. Although the advantages of perioperative treatment are not proven, this concept has become more and more popular in recent years, mainly because of a lack of guidelines. Thus the aim of our study is to compare the complication rate of both therapeutical concepts. Furthermore, secondary objectives (disease-free survival, overall survival, resection rates, response rates, toxicities and quality of life) will be used to estimate the efficacy, feasibility, and safety of both regimens. Perioperative treatment probably has a better efficacy in patients with high tumor burden (>3 liver metastases or one metastasis > or = 5 cm in diameter) with effect on disease free survival and will be investigated in a subgroup analysis.

Criteria

Inclusion Criteria:

  • Signed written informed consent obtained prior to any study-specific procedure.
  • Age > 18 years
  • Proven K-RAS wildtype in primary tumour or metastasis tissue
  • Diagnosis of resectable metachronous metastases after complete resection (R0) of primary tumour without gross or microscopic evidence of residual disease. or Diagnosis of resectable synchronous metastases after complete resection (R0) of primary tumour more than 1 month before study or Diagnosis of resectable synchronous metastases with sufficient evidence (i.e., CT scan or diagnostic laparoscopy) that both the primary tumour and liver metastases can be completely resected during the same procedure and resection of primary can be delayed 3-4 months.
  • Negative pregnancy test
  • Highly effective contraception during treatment and for at least 3 months thereafter in women (defined as pearl index < 1) and men, if the risk of conception exists
  • Planned start of study medication between 0 and 3 weeks post randomization
  • ECOG performance status 0 or 1 (Appendix 1)
  • Adequate hematology: neutrophils > 1,5 /nl, platelets > 100/nl, INR < 1,5, aPTT < 1,5 x UNL
  • Adequate biochemistry: total bilirubin < 1,5 x UNL, ASAT and ALAT < 5 x UNL, alkaline phosphatase < 5 x UNL, serum creatinine < 1,5, x UNL.

Exclusion Criteria:

  • Patients with any relationship of dependence to the sponsor or the investigator
  • Patients committed to an institution (court-ordered or by official orders)
  • Extrahepatic metastatic disease
  • Proven K-RAS mutation or unknown K-RAS mutational status in tumour tissue
