Group/Cohort Intervention/treatment
Bevacizumab
Participants with metastatic colorectal cancer (mCRC) with exclusively liver or liver and lung metastases, who were receiving bevacizumab as part of first line treatment for potentially resectable liver metastases will be observed.
 Drug: Bevacizumab
Participants with mCRC and having exclusively liver or liver and lung metastases who were receiving bevacizumab as part of first line treatment for potentially resectable liver metastases as per treating physician's discretion will be observed. All concomitant medications as used in routine clinical practice are allowed.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Percentage of Participants Without Detectable Metastatic Disease After Secondary Resection Post Surgery [ Time Frame: Baseline up to 36 months ]
    Secondary resection involves removal of all detectable metastases at surgery including participants with missing metastases left in place. Percentage of participants without detectable metastatic disease after secondary resection removing all detectable metastases at surgery (including participants with disappeared metastases left in place [missing metastases]) was reported. Metastases was detected using computed tomography (CT) scan or magnetic resonance imaging (MRI).

  2. Percentage of Participants Without Detectable Metastatic Disease After a Complete Response Without Surgery [ Time Frame: Baseline up to 36 months ]
    The percentage of participants with no detectable metastatic disease after a complete response without surgery (missing metastasis) was reported.


Secondary Outcome Measures :
  1. Percentage of Participants With at Least One Disease and Comorbidity at Day 0 [ Time Frame: Day 0 ]
    Percentage of participants who had any concurrent disease (comorbidity) at Day 0 was reported. Comorbidities included gastrointestinal disease, hypertension, other cardiovascular disease, and other medical history and comorbidities (other than those specified above). Same participant may be counted in more than one category.

  2. Percentage of Participants With Different Previous Therapies at Day 0 [ Time Frame: Day 0 ]
    Previous therapies included neoadjuvant treatment (chemotherapy or chemotherapy + radiotherapy) and adjuvant treatment (FOLFOX [folinic acid+5-fluorouracil+oxaliplatin], LV5FU2 [leucovorin+5-Fluorouracil], capecitabine, or any other adjuvant treatment). Only participants who received neoadjuvant treatment and adjuvant treatment was reported.

  3. Mean Number of Cumulated Cycles of Bevacizumab Over the Study Period [ Time Frame: Baseline up to 36 months ]
  4. Percentage of Participants Who Received at Least One Chemotherapy Over the Study Period [ Time Frame: Baseline up to 36 months ]
  5. Percentage of Participants With at Least One Comorbidity Post Bevacizumab Treatment [ Time Frame: Baseline up to 36 months ]
    Percentage of participants who had any concurrent disease (comorbidity) was reported. Comorbidities included gastrointestinal disease, other cardiovascular disease, and other medical history and comorbidities (other than those which are specified above). Same participant may be counted in more than one category.

  6. Percentage of Participants With Disease Progression or Death [ Time Frame: Baseline until disease progression or death, whichever occurred first, assessed up to 36 months ]
    Disease progression is defined at least a 20 percent (%) increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 millimeter (mm) or persistence of non-target lesions, or appearance of one or more new lesions.

  7. Progression-free Survival (PFS) [ Time Frame: Baseline until disease progression or death, whichever occurred first, assessed up to 36 months ]
    Progression-free survival defined as the time elapsed between the Avastin start date and the date of first progressive disease (PD) or death. Kaplan-Meier estimate was used for evaluation. PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or persistence of non-target lesions or appearance of one or more new lesions.

  8. Percentage of Participants With Disease Relapse [ Time Frame: Baseline until disease progression or death, whichever occurred first, assessed up to 36 months ]
    Relapse was defined as the presence of metastases post last surgery removing all detectable metastases (A1 criterion [participants without detectable metastatic disease {DMD} after secondary resection removing all detectable metastases at surgery {including participants with missing metastases}]) and the date of first PD or death. PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or persistence of non-target lesions, or appearance of one or more new lesions.

  9. Relapse-free Survival (RFS) [ Time Frame: Baseline until disease progression or death, whichever occurred first, assessed up to 36 months ]
    RFS was defined as the time elapsed between the last surgery removing all detectable metastases (A1 criterion [participants without DMD after secondary resection removing all detectable metastases at surgery {including participants with missing metastases}]) and the date of first PD or death. PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or persistence of non-target lesions, or appearance of one or more new lesions.

  10. Percentage of Participants Who Died [ Time Frame: Baseline until death; assessed up to 36 months ]
  11. Overall Survival (OS) [ Time Frame: Baseline until death, assessed up to 36 months ]
    OS time is defined as time between start of therapy and date of death. Kaplan-Meier estimate was used for evaluation.

  12. Percentage of Participants With Histologically Viable Tumor Cells With Resected Non Detectable Hepatic and Pulmonary Metastases Post Surgery [ Time Frame: Baseline up to 36 months ]
    For the non-detectable liver and lung metastases the categorization based on rate of viable cells were as follows (no viable cells =0%, minimum =1 to 49%, maximum =50 to 100%).

  13. Number of Cumulated Cycles of First Line Bevacizumab at Day 0 [ Time Frame: Day 0 ]
  14. Percentage of Participants With Different Doses of First Line Bevacizumab at Day 0 [ Time Frame: Day 0 ]
  15. Total Duration of First Line Bevacizumab Treatment at Day 0 [ Time Frame: Day 0 ]
  16. Percentage of Participants With Unresectability Criteria [ Time Frame: Day 0 ]
