RATIONALE: Genetic studies may help in understanding the genetic processes involved in the development of some types of cancer.

PURPOSE: Clinical trial to study the cancer-related genes in patients who have colon cancer or adenomatous polyps.

Condition Intervention
Colorectal Cancer
Genetic: cytogenetic analysis
Genetic: gene mapping
Genetic: microarray analysis

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Familial Factors in the Development of Colon Cancer

Further study details as provided by Alliance for Clinical Trials in Oncology:

Enrollment: 600
Study Start Date: December 2001
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Group 1

Patients donate blood samples for analysis of colorectal susceptibility genes. Patients also complete a questionnaire regarding family cancer history.

A certificate of confidentiality protecting the identity of research participants in this project has been issued by the National Cancer Institute.

Participants do not receive the results of the genetic testing, and the results do not influence the type or duration of treatment.

Detailed Description:


  • Identify human colon neoplasia susceptibility genes in patients with colon cancer or adenomatous polyps.
  • Correlate the inheritance of novel susceptibility alleles for adenomatous polyposis of the colon with colon neoplasia in these patients.
  • Correlate colon neoplasia susceptibility with the presence of COX-2, sPLA2, and DNMT genes in these patients.
  • Identify a novel gene that governs increased susceptibility to colon adenoma and cancer in the genome of these patients.

Ages Eligible for Study:   up to 70 Years   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients diagnosed with colon cancer or polyps age 70 or under. Specifically, patients previously enrolled on CLB-9581, CLB-89803 and CLB-80001.


  • Diagnosis of colon cancer or polyps at age 70 or under
  • Has a living full sibling with diagnosis of colon cancer or polyps at age 70 or under
  • No history of familial adenomatous polyposis syndrome
  • No hereditary nonpolyposis colon cancer, according to Amsterdam criteria
  • No known I1370K adenomatous polyposis of the colon susceptibility variant
  • Enrolled on 1 of the following clinical trials:

    • CLB-9581
    • CLB-89803
    • CLB-80001 NOTE: Patients do not need to be receiving protocol therapy. Patients who are outside the treatment protocol's follow-up range are eligible. Patients who discontinued therapy for any reason, including toxic effects, are eligible.



  • 70 and under at diagnosis


  • No significant psychiatric illness that would preclude giving informed consent
  • No inflammatory bowel disease (in patient or sibling)
