摘要
Mitomycin-C (MMC) induced Chromosomal aberration (CA) frequencies were studied in 48 h peripheral blood lymphocyte (PBL) cultures of untreated cancer patients of young age (maximum age 12 years, n = 77). Control population (n = 71) consisted of age-matched group (maximum age 12 years, n = 21); elder controls (minimum age 60 years, n = 19) and healthy first degree relatives, i.e., parents or siblings of the pediatric cancer patients (mean age 24.3 years, n = 31) as they share their genome and environment. Induced CA levels were found to be significantly higher among pediatric cancer patients as compared to control groups. The age-matched and elder control groups showed comparable CA levels. The first degree relatives controls showed higher induced CA levels as compared to pediatric and elder control groups. The present results indicate that there are different degrees of mutagen sensitivity prevailing in normal population. This may be responsible for differential cancer proneness. High degree of mutagen sensitivity in cancer patients may also be playing a major role in cancer onset at an early age. (C) 1998 Elsevier Science B.V. All rights reserved.
