The news is just another blow to Prempro, a combination of estrogen and progestin that was widely prescribed to women as a treatment for menopausal symptoms. Prempro and other HRTs were once thought to improve a woman’s health as she entered postmenopausal years; however, results from a Women’s Health Initiative (WHI) shook that belief when the findings of that study revealed women on HRT were at an increased risk of breast cancer and cardiovascular disease. Since 2002, when the findings were released, sales of HRT medications like Prempro have plummeted and lawsuits against companies like Wyeth have escalated.

According to the new trial, which reviewed women from WHI age 50 to 79, after five years on Prempro 67 women died from non-small cell lung cancer compared with 39 on a placebo. The study group included both current and former smokers.

“This is a new finding that tells us women who smoke shouldn’t take estrogen and progestin for menopause symptoms,” said Rowan Chlebowski, the study author and a researcher at Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center.

According to the study, among the women classified as current or former smokers, there were 56 deaths among women taking hormones and 34 deaths among women on a placebo. Among the women classified as nonsmokers, there were 9 deaths for women on HRT and 5 deaths for those taking a placebo.
