Researchers found that women who took the breast cancer drugs were 30 percent less likely to have their cancer return over the next nine years. The drugs essentially starve potential cancers of estrogen, which can cause menopause-like symptoms in the women who take them. While the side effects may be discouraging, they may also be showing how well the treatment is working.

Researchers looked at 4,000 post-menopausal women who took AstraZeneca’s Arimidex, also known as anastrozole, or tamoxifen. Arimidex can only be taken by women who already have gone through menopause. The study showed that women who reported the menopause-like side effects within three months of treatment were more likely to remain cancer free.

Breast cancer is one of the most common forms of cancer among women, and the second most common cause of cancer death among women. According to Breast Cancer: Network of Strength, female breast cancer incidence rates continuously increased for two decades, but have leveled off since 2001. The organization theorizes that one possible explanation for the decrease is that millions of women stopped taking hormone replacement therapy (HRT) following the Women’s Health Initiative of 2002, which indicates a positive link between taking HRT and developing breast cancer.

Premarin is a low-dose mixture of estrogen hormones and is already available in pill form to treat symptoms of menopause such as hot flashes and vaginal dryness, burning and itching. Premarin and another Wyeth drug prescribed for menopausal symptoms, Prempro, dominated the hormone replacement therapy market until the Women’s Health Initiative of 2002 linked long-term use of HRT to an increased risk of breast cancer and other serious health problems. Wyeth has since been faced with numerous lawsuits concerning the drugs.

Dyspareunia is a disorder that follows the atrophy or thinning of the vagina and vulva, a condition that can occur in menopause.

The .5-gram cream has two dosing regiments – 21 days on followed by 7 days off, or twice weekly. FDA approval of the cream and its dosing regime was granted based on results from a multi-center clinical study that included a 12-week, randomized, double blind placebo phase followed by a 40-week open-label phase, according to the story.

Wyeth advises women considering the cream to review possible side effects with their physician, and to avoid the product if they fall into a high-risk category.

According to the report, Kings College London researchers tracked 442 female breast cancer survivors for more than four years, half of which had been given HRT. The women who were taking HRT had a 14 percent higher recurrence rate than those who did not take HRT.

All women tracked participated in the 2002 U.S. government-sponsored Women’s Health Initiative, which studied the effects of HRT on women. That study was halted after researchers found that HRT led to an increased risk of dangerous medical conditions such as breast cancer, heart attack, stroke and blood clots.

In a related commentary in the Journal of the National Cancer Institute, Dr. Kathy Prichard of Canada’s Sunnybrook Odette Cancer Center, indicated that the data is convincing. “It seems that the harmful side effects of HRT (in breast cancer survivors) have finally been clearly demonstrated in what is, by today’s standards, a small randomized trial, carried out in a few relatively small countries,” Dr. Pritchard wrote.

Researchers analyzed data from 38 observational studies involving more than 2.7 million women to see whether taking non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen, reduced risk of breast cancer. Inflammation may be a risk factor in cancer, the report says.

Earlier studies on NSAIDS in reducing breast cancer risk have shown conflicting results. Reviewers hope that by combining results they may identify trends that individual studies may miss.

NSAIDs work through the suppression of estrogen, which has researchers speculating that the use of NSAIDs may reduce the risk of hormone-positive breast cancer. Hormone-positive breast cancer, also referred to as estrogen receptor (ER)-positive breast cancer, is the most common type of breast cancer and is stimulated to grow from exposure to the female hormones estrogen and/or progesterone, according to the Daily Cancer News –CancerConsultants.com.

According to the report, women who regularly took any type of NSAIDs had a 12 percent reduction of breast cancer risk. While the news is promising, the report urges that women should first consult their healthcare provider before using any NSAIDs, as these medications can have side effects that carry risks that outweigh the benefits against breast cancer.

For years, HRT was considered the cure-all for menopausal symptoms that range from hot flashes and riding the emotional roller coaster to bone loss and osteoporosis. But a 2002 study by the Women’s Health Initiative (WHI) and funded by the National Institutes of Health stopped women and their doctors in their tracks when the research revealed that the risks of HRT far outweighed and outnumbered the benefits. The WHI report stated that long-term use of estrogen/progestin therapy led to a 26 percent increase in breast cancer, not to mention a laundry list of other serious side effects.

The American Cancer Society suggests women talk with their own doctors before deciding whether HRT is right for them. The organization also suggested women heed the advice of the WHI, which includes not continuing or starting HRT to prevent heart disease; to discuss their risk of heart attack, stroke, blood clots and breast cancer before taking HRT for osteoporosis prevention; and to perform regular breast self-exams and schedule annual mammograms.

Using HRT for the short-term may be a safer alternative, the report states, however, “Given these results, we recommend that clinicians stop prescribing this combination for long term use. ‘Primum non nocere’ [First, do no harm] applies especially to preventive health care.”

Prempro and Premarin , along with Provera, which is made by Pfizer, have come under attack in recent years as mounting evidence revealed that the drugs can increase the risk of developing breast cancer. Plaintiffs lodging claims against the drug makers argue that the manufacturers failed to voice sufficient warning about the increased risk of developing breast cancer that the drugs present. Approximately 5,000 women have filed lawsuits against Wyeth, contending that the company’s HRTs (hormone replacement therapies) caused them to develop breast cancer.

A study monitoring 3,400 recipients of Aprela indicated no evidence of increased breast cancer rates, compared with women who received Evista or placebo. Aprela recipients also showed the same relatively lower rates of breast tenderness and pain as Evista and placebo recipients – a significant benefit considering that breast discomfort is the main reason why stop using menopause drugs

Other studies revealed that Aprela recipients experienced better sleep and diminished hot flashes compared to women who were treated with placebo. Increased bone density, improved sexual function, and less vaginal dryness were also evident in late-stage tests of Aprela.

Wyeth will submit Aprela to the FDA for approved use in the second half of 2009. If approved, the drug may provide a better line of treatment for postmenopausal women. Its marketing would also help the company offset continual losses resulting from its Prempro suits.

Scharlotte Fitzgerald says she began taking hormone replacement drugs in 1994. In 2001 she was diagnosed with breast cancer.

Fitzgerald and her husband Larry filed a personal injury suit against the drug companies in the Beaumont Division of the Eastern District of Texas on Nov. 2. They are seeking in excess of $75,000 in damages.

“This lawsuit asserts claims for negligence; strict product liability for failure to warn, strict product liability for design defect; and breach of implied warranty against the defendants responsible for the design, manufacture, production, testing, study, inspection, mixture, labeling, marketing, advertising, sales, promotion and/or distribution of those hormone therapy products that caused her breast cancer,” the plaintiffs’ original complaint states.

The plaintiffs’ claim that the defendants had an obligation to provide warnings about risks and side effects of their hormone therapy drugs as soon as it was aware of them. The suit alleges that the drug companies failed to disclose “an increased incidence and risk of strokes, blood clots, heart attacks, breast cancers and ovarian cancer from these drugs.”

Plaintiffs also assert that the defendants made claims regarding health benefits of the drugs and should have known “that these claims were false and misleading.”

The defendants also gave a false impression that adequate pre-marketing clinical testing and research and post-marketing surveillance had been done, the plaintiffs claim.

“Plaintiff would not have ingested the hormone therapy drugs … or would have discontinued their use, or would have used safer alternative methods, had defendants disclosed the true health consequences, risks, and adverse effects, including the increased incidence and risk of breast cancer and other illnesses, caused by their hormone drugs,” the complaint states.

In the first claim against defendants, the plaintiff alleges that the companies were negligent by failing to exercise reasonable care in designing, manufacturing, testing and distributing the hormone replacement drugs.

“Defendants knew or should have known that their hormone therapy drugs caused unreasonable harm and dangerous side effects that many users would be unable to remedy by any means,” the petition states. “Despite this, defendants continued to promote and market their hormone therapy drugs for use by consumers, including plaintiff, when safer and more effective methods of countering the negative health effects of menopause were available.”

The petition also includes claims for strict liability through failure to warn and design defect.

“These hormone therapy drugs were each dangerous to an extent beyond that which would be contemplated by the ordinary consumer who purchased them,” the suit says. “They were more dangerous than plaintiff contemplated. The risk of each of these hormone therapy drugs outweighs its utility.”

The companies also breached implied warranty, the suit said, because the sold the drugs as being of “merchantable quality and safe and fit for their intended use.”

Scharlette Fitzgerald is seeking damages to exceed $75,000, attorney fees, costs of suit and other relief that the court may deem just and proper.

Her husband, Larry Fitzgerald is also seeking monetary damages for his loss of spousal services, society and companionship.
