1. We will evaluate and compare predictors of health-related quality of life (QOL) among colorectal cancer (CRC) survivors who have Lynch syndrome (LS) with those patients who have sporadic CRC using both quantitative and qualitative methodology.
a. In both CRC groups, we will evaluate cancer preventive and health behaviors, including lifestyle factors and screening, psychosocial factors, including mood, family functioning, coping style, anxiety, depression, and social resources, and health care system factors, including interactions with health care providers and service utilization.
2. We will compare the experience of first-degree relatives (FDRs) of patients who have LS with that of FDRs of patients who have sporadic CRC using both quantitative and qualitative methodology.
a. We will evaluate all of the domains listed above, as well as anticipatory grief, assessment of caregiving responsibilities, and fear of cancer in FDRs of patients with LS-related and sporadic CRC.
3. We will examine CRC patients from both groups and their FDRs using dyadic analyses in order to evaluate the similarities and differences in their survivorship experience.
4. We will evaluate the preventive and health behavior of patients who are non-conclusive for Lynch syndrome and their family members. We will examine their screening behavior and will explore how the interaction between the patients and their relatives affects the relatives' screening behavior. We also will examine how these non conclusive LS patients and their family members perceive their risk for LS-related cancers.
Data will be collected primarily using a mailed self-administered questionnaire. A subset of the participants who complete the mailed questionnaire will be recontacted and invited to participate in an in-depth, semi-structured telephone interview.
Qualitative Mailed Questionnaires:
Participants will complete a questionnaire that contains questions about your experiences living with colorectal cancer. The questionnaire should take 45-60 minutes to complete.
Up to 200 colorectal cancer survivors and up to 200 close relatives of colorectal cancer survivors will take part in this portion of the study.
In the phone interview, you will be asked some questions about your experiences living with colorectal cancer. The phone interview should take 30-45 minutes to complete.
Up to 30 colorectal cancer survivors and up to 30 close relatives of colorectal cancer survivors will take part in this portion of the study.

Digoxin has been shown to be impact on a number of pathways that are of relevance to cancer and its use has been associated with increased risks of breast and uterus cancer and, more recently, a 40% i...
Cyclin B1, a mitotic cyclin, has been implicated in malignances. However, its contribution to colorectal cancer invasion and metastasis are still not well understood. Here, we demonstrated that the in...
Treatment options for colorectal cancer patients create the need to assess the quality of life (QoL) of colorectal cancer patients in the early postoperative period when changes are potentially greate...
Self-rated health (SRH) is a consistent predictor of mortality and other health outcomes. One of the mechanisms hypothesized to explain its validity as a predictor is that SRH affects the adoption of ...
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).
Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
Self-administered health questionnaire developed to obtain details of the medical history as an adjunct to the medical interview. It consists of 195 questions divided into eighteen sections; the first twelve deal with somatic complaints and the last six with mood and feeling patterns. The Index is used also as a personality inventory or in epidemiologic studies.
