Gender effect

Dr. Hastings is establishing how parathyroid hormone-related protein (PTHrP) slows lung cancer growth, evaluating why lung cancers in men are less sensitive to PTHrP, and testing whether changes in hormone levels can affect the growth of lung cancer cells. His research may also determine whether changing the levels of male hormones makes it possible to improve the response to PTHrP.

Dr. Cote is examining the role of estrogen-related tumor characteristics in predicting differences in survival between men and women after a lung cancer diagnosis. The identification of molecular and genetic profiles associated with survival will help target treatment advances and customize treatment for male and female lung cancer patients.

The role of the hormone estrogen in the development of lung cancer has been established. Dr. Heymach is studying how estrogen affects signaling by the EGFR gene and secretion of proteins that fuel the development of new blood vessels necessary to sustain the growth of the cancer.

NNK is a powerful nicotine-derived carcinogen. Dr. Schuller is determining the exact role of estrogen in tumors caused by NNK. This understanding will provide new targets for the early diagnosis, prevention, and therapy of lung cancer in women.

Previously conducted clinical trials have suggested an increased risk of lung cancer from hormone replacement therapy (HRT). Dr. Slatore is studying women who have both undergone HRT and smoked  to determine whether there is a relationship between HRT, tobacco use, and lung cancer.
