Study of Blood and Tumor Samples From Men With an Inherited Risk of Prostate Cancer

2014-08-27 03:20:02 | BioPortfolio

Summary

RATIONALE: Studying samples of blood and tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify genes related to cancer.

PURPOSE: This clinical trial is studying blood and tumor samples from men with an inherited risk of prostate cancer.

Description

OBJECTIVES:

- To find genes that predispose to prostate cancer (using genetic linkage and other molecular biology techniques).

- To determine if genes that predispose to prostate cancer are associated with disease and treatment parameters.

- To determine if genes that predispose to prostate cancer are associated with environmental factors.

- To estimate the percentage of prostate cancer patients who have a positive family history of the disease.

- To estimate the relative risk of developing prostate cancer in a currently unaffected member of a prostate cancer family.

- To ascertain whether relatives of prostate cancer patients are at increased risk of developing cancers other than prostate cancer.

- To build up a large blood and tumor (both fresh and preserved) bank from patients with prostate cancer to identify prostate cancer predisposition gene(s), determine the prevalence and penetrance of prostate cancer predisposition genes in prostate cancer patients, correlate changes in prostate cancer predisposition gene(s) with disease and treatment parameters by matching with clinical data from clinical databases already held as part of the medical record on these patients, and correlate changes in prostate cancer predisposition gene(s) with environmental factors collected by questionnaire from these patients.

- To use the blood and tumor bank for marker studies (DNA, RNA, serum, plasma, protein, and other molecules) to define the role of these markers in disease prediction and progression.

- To develop microarrays from prostate cancers to determine their genetic profile and correlate this with prostate cancer genetic predisposition genes.

- To collect tissue from other unaffected and affected members of the family in cases where a genetic alteration is found, in order to ascertain whether this alteration is associated with disease risk.

- To collect tissue samples from unaffected family members who show an interest in taking part in the study.

OUTLINE: Patients are assessed by a family history and epidemiology questionnaire and undergo a medical record review.

Patients and relatives with prostate cancer may undergo blood sample collection for genetic analysis of prostate cancer predisposition genes and measurement of markers of associations with genetic changes associated with prostate cancer. Blood and tumor samples are stored for future studies.

Medical and Biotech [MESH] Definitions

Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment.

Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.

Organizations representing designated geographic areas which have contracts under the PRO program to review the medical necessity, appropriateness, quality, and cost-effectiveness of care received by Medicare beneficiaries. Peer Review Improvement Act, PL 97-248, 1982.

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.

An organized procedure carried out through committees to review admissions, duration of stay, professional services furnished, and to evaluate the medical necessity of those services and promote their most efficient use.
