Abstract

Gestational breast cancer (BC) is generally associated with rapid growth and increased mortality. Because the presence of MMTV-like sequences in BC has been associated with laminin receptor expression, a marker of poor prognosis, gestational BCs were analyzed for MMTV env gene-like sequences to explore whether MMTV-like sequences were also associated with its adverse outcome. Whereas 30–38% of sporadic BC have the sequences, in gestational BC the prevalence is 62%. We suggest that hormonal response elements present in the MMTV-like LTR may play a role in promoting cell growth, as they do in the mouse system.
