Primary Outcome Measures:
  • Mutational status of KRAS: study of codons 12 and 13 in exon 1 of KRAS gene [ Time Frame: Initial visit (Day 1) and subsequent visit till the end of the study ]

Secondary Outcome Measures:
  • Subject and tumour characteristics and their association with KRAS mutational status [ Time Frame: Initial visit (Day 1) and subsequent visit till the end of the study ]

Enrollment: 1524
Study Start Date: June 2009
Study Completion Date: August 2013
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Detailed Description:

This is an observational, prospective, non-interventional, single arm, non-comparative, open label, multi-centric, multi-stage study to record the prevalence of KRAS mutations in the Argentine mCRC population. The study is planned to be conducted in 150 centres (50 in each of 3 stages of four months each, enrolling 500 subjects in each stage). Total of subjects: 1500. Demographic information, complete medical history and tumour history related data will be captured in the first visit and if any information is missing, then only another visit will be scheduled. Data captured will be analysed and presented using statistical tools.


Primary objective:

  • To record the prevalence of KRAS mutations in the Argentine mCRC population.

Secondary objective:

  • To record and evaluate certain subject and tumour characteristics for association with KRAS mutational status (country, gender, age, performance status, body mass index (BMI), ethnic origin, personal and family history of malignancy, personal and family history of familial polyposis coli, smoking status, exercise, diet, tumour characteristics/location, site of origin of the tissue sample sent for KRAS testing, first line therapy chosen).

Ages Eligible for Study:   22 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Subjects with histologicaly confirmed metastatic adenocarcinoma of the colon/rectum in Argentina

Inclusion Criteria:

  • Subjects willing to provide information required by protocol
  • No previous systemic treatment for mCRC

Exclusion Criteria:

  • Subjects with known pregnancy
