Cancer Risk in Individuals Who Have a Xeroderma Pigmentosum Gene Alteration Compared With Those Who Don't - Full Text View

Purpose

RATIONALE: Screening individuals who have a xeroderma pigmentosum gene alteration may help doctors identify persons at risk of developing cancer and identify other cancer genes.

PURPOSE: This clinical trial is comparing cancer risk in individuals who have a xeroderma pigmentosum gene alteration to those who don't.

Further study details as provided by National Cancer Institute (NCI):

Estimated Enrollment:	800
Study Start Date:	August 2002

Detailed Description:

OBJECTIVES:

Compare risk of developing any type of cancer in participants who are heterozygous carriers of xeroderma pigmentosum (XP) disease gene mutations vs non-carrier blood relatives or spouses.
Compare risk of developing skin cancers or cancers of the nervous system in these participants.
Compare cancer risk in different groups among heterozygous carriers of XP disease gene mutations.
Compare cancer risk in carriers of different XP disease gene mutations with heterozygous carriers of these gene mutations.

OUTLINE: Participants undergo general cancer screening comprising a medical history and physical examination, including a skin and neurologic examination. Laboratory samples are collected for review.

Participants are followed annually by telephone or mail to determine clinical status.

PROJECTED ACCRUAL: Approximately 800 participants (400 heterozygous carriers and 400 non-carrier blood relatives or spouses) will be accrued for this study.
