Chemotherapy and/or Metastasectomy in Treating Patients With Metastatic Colorectal Adenocarcinoma With Lung Metastases

Titre officiel

The Role of Multimodality Management in Risk-Stratified Patients With Lung-Limited Metastatic Colorectal Cancer

Sommaire:

This phase II trial studies how well chemotherapy and/or metastasectomy work in treating patients with colorectal adenocarcinoma that has spread to the lungs (metastases). Drugs used in chemotherapy work in different ways to stop the growth of tumour cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Metastasectomy is a surgical procedure that removes tumours formed from cells that have spread from other places in the body. It is not yet known if chemotherapy and metastasectomy together works better in treating patients with metastatic colorectal adenocarcinoma with lung metastases.

Description de l'essai

Primary Outcome:

  • Recurrence-free survival (Low risk)
  • Overall survival (High risk)
PRIMARY OBJECTIVES:
I. To compare recurrence-free survival in patients with "low risk" lung-limited metastatic colorectal cancer (mCRC) undergoing pulmonary metastasectomy with or without perioperative chemotherapy. II. To compare overall survival in patients with "high risk" lung-limited mCRC receiving systemic chemotherapy with or without surgical resection. SECONDARY OBJECTIVES:
I. To compare grade 3 and 4 adverse events in patients receiving surgical resection and/or chemotherapy in the management of lung-limited mCRC. EXPLORATORY OBJECTIVES:
I. To evaluate for changes in circulating tumour deoxyribonucleic acid (DNA) following surgical resection and/or systemic chemotherapy in patients with lung-limited mCRC. OUTLINE:

Patients are assigned to 1 of 2 risk groups (low or high). GROUP 1 (LOW RISK): Patients are randomized to 1 of 2 groups. GROUP 1A: Patients receive standard of care chemotherapy for 3 months prior to and 3 months after undergoing metastasectomy in the absence of disease progression or unacceptable toxicity. GROUP 1B: Patients undergo metastasectomy. GROUP 2 (HIGH RISK): All high risk patients receive standard of care chemotherapy for 3 months in the absence of disease progression or unacceptable toxicity. Patients without progressive disease after 3 months are then randomized to 1 of 2 groups. GROUP 2A: Patients undergo metastasectomy. GROUP 2B: Patients continue standard of care chemotherapy for 6 months in the absence of disease progression or unacceptable toxicity. Patients with stable disease or radiographic response after 6 months may then cross over to Group 2A. After completion of study treatment, patients are followed up periodically for up to 5 years.
