Non-Small Cell Lung Cancers in Women and Men: Differences in Biology, Behavior, and Outcomes.
Lung cancer is the leading cause of cancer deaths in men and women, both because of its high incidence rates and poor prognosis without effective therapies. Environmental carcinogens, most predominantly tobacco smoke, play a significant role. There are continuously emerging data to suggest the biological process differs between lung cancers in men and women. Differences are seen in a variety of cellular pathways and responses to carcinogens and therapies. Particular note in this article is made of carcinogen processing by cytochrome P450s, estrogen receptor pathways, epidermal growth factor receptor mutations, and how these are not necessarily independent cellular processes. These topics are only very briefly summarized here and it was not possible to include many important references. The heterogeneity of lung cancers in men and women, as well as smokers and nonsmokers, are likely to become more apparent with further studies. Work previously done in our laboratory (EDRN, PIs David Chia & Lee Goodglick) served to further emphasize these differences. This report is dedicated to the memory of Lee Goodglick with whom I had the privilege to work for many years prior to his untimely death.
