The sarcoma, breast cancer, lung cancer, and adrenocortical carcinoma syndrome revisited. Childhood cancer
H. T. Lynch, D. A. Katz, P. J. Bogard and J. F. Lynch
We studied two children who had rhabdomyosarcoma and glioblastoma and who
were from a family with a hereditary cancer syndrome that was characterized
by sarcoma, breast cancer, brain tumors, lung cancer, laryngeal carcinoma,
leukemia, and adrenocortical carcinoma. The deleterious genotype has now
been expressed through the fourth generation of this large kindred. The
pedigree emphasizes the need for an extended history of several generations
to arrive at a hereditary-syndrome diagnosis. A limited pedigree may result
in nonappreciation of the genetic component. The pedigree illustrates that,
in certain circumstances, the highly specific varieties of cancer may occur
in children before it is expressed in the parent who carries the putative
gene. Pediatricians, in evaluating the causes of childhood cancer, must be
cognizant of cancer among adult relatives, since this recognition may aid
in the diagnosis of those hereditary cancer syndromes that are
characterized by cancer occurrence in children as well as adults.
