Guest guest Posted March 22, 2006 Report Share Posted March 22, 2006 Thanks to Patty, creator of the Saline Support Group .... www.BreastImplantAwareness.org/Patty.html EXCERPT: During the Stern trial an expert witness named Marc Lappe, called by the plaintiff to comment on the study, pointed out the discrepancies between the published study and the internal reports. Dow Corning lawyers tried unsuccessfully to have Lappe’s testimony excluded. The judge then asked to see the documents both Lappe and the Dow Corning lawyers brought into court, and noticed that the identifying numbers on the dogs had been altered on the documents Dow Corning had given the attorneys. It looked suspiciously like the company had altered the data to make it more difficult to get at the full two-year results of the study. http://66.102.7.104/search?q=cache:fLIvZlHnSjcJ:www.foodsafetynetwork... ------------------------------------------------------------------------------\ -- Page 1 173•5• Silicone Breasts: Dow Corning and the Implant Lawsuits by Conrad G. Brunk, with the assistance of Leiss The Litigation Against Dow Corning In May 1995 Dow Corning Corp. announced that it was seeking bankruptcy protection in response to rapidly escalating numbers of compensation claims for alleged harms suffered by women who had been surgically fitted with the silicone breast implants manufactured by the company. The company had been found liable for large awards by juries who were convinced by the testimony of ------------------------------------------------------------------------------\ -- Page 2 174 women and their physicians that a whole range of health problems they suffered were caused by the implants manufactured by Dow Corning and several of its competitors. One of the first of these lawsuits had been brought over ten years earlier, in 1984, when a California jury awarded Stern $1.7 million in damages for illnesses it was convinced had been caused by Dow Corning’s implants. The court found Dow Corning guilty of fraud in its handling of information the company possessed concerning the risks to women from its implants.1The flood of litigation against Dow Corning did not really begin until 1991, however, when a San Francisco jury awarded nn Hopkins $7.3 million because of its finding that Dow Corning implants were defective and that the company was guilty of fraud.2 After the Hopkins decision the U.S. Food and Drug Administration (FDA) announced a moratorium on the sale of the implants, reinforcing an avalanche of court suits filed against Dow Corning. By the end of 1992 the number of pending suits had increased from 137 to 3,558. By the end of 1993 the number had reached more than 12,0003and by 1994 19,092 cases had reportedly been filed against Dow Corning. After many of these suits had been consolidated into a class-action proceeding, an Alabama judge approved a tentative $4.5 billion (U.S.) settlement between several implant manufacturers and women who filed injury claims with the court, the largest class action settlement in history. Dow Corning, which manufactured nearly 30% of the over 2 million breast implants placed in ------------------------------------------------------------------------------\ -- Page 3 175 women’s bodies, agreed to pay nearly half of this $4.5 billion.4 The other half of the liability was shared among several other companies: Bristol-Meyers Squibb, 3-M Company, and Baxter International, among them. The Alabama settlement was not the end of Dow Corning’s liabilities, however, since the court left the door open for claims from additional women to be brought against the company. More claims were forthcoming, including actions on behalf of an estimated 50,000 Canadian women, most of whom had been excluded from the Alabama settlement.5Once Dow Corning’s pockets were emptied by these large settlements, plaintiffs turned to the deeper pockets of Dow Chemical, alleging that this parent company of Dow Corning shared liability because it had carried out some of the early studies on the potential affects of silicone on the immune system.6 By 1995 over 440,000 women had registered in the global settlement against Dow Corning. The Risk Communication Angle If a final class-action settlement confirms Dow Corning’s bankruptcy declaration, this will mean the loss of their company by existing shareholders as a result of litigation over a product which represented only one percent of the company’s total sales. The tentative class-action settlement entailed unprecedented court awards for alleged damages for which there was, and remains, little reliable scientific evidence. Despite the scarcity of scientific evidence for many of the alleged risks, juries had been accepting the contention ------------------------------------------------------------------------------\ -- Page 4 176 that silicone breast implants posed clearly unacceptable risks for a wide variety of autoimmune and connective tissue diseases, as well as many other severe disabilities suffered by women. This public perception of the risk supported the willingness of numerous juries and judges to be persuaded that Dow Corning was guilty of “injuring” many women and consequently ought to be liable for high levels of punitive damages. The Dow Corning case raises fundamental issues about the relationship between science and public regulatory policy, as well as between “expert” and “lay” perceptions of risk. Risk communication is, in part, the art of effective bridge-building across the often wide spaces that separate these domains; if this artistry is maladroit there can be disastrous repercussions on various levels, economic, political, and personal. In the case of Dow Corning, the early failure to assess the human health risks of silicone implants and to communicate effectively the nature of these risks — and the uncertainties associated with them — led to such a disaster. The story of Dow Corning’s handling of the risk issues associated with silicone breast implants illustrates how easily a company can become the victim of its own mismanagement of risk and risk information. Some prominent members of the medical-scientific hold that the implants pose little or no risk for the type of ailments ascribed to them by public opinion and the courts. We believe that Dow Corning’s management of the risk issues is in large part responsible for this discrepancy. It was the public revelation of Dow Corning’s apparent failure to conduct a fully sufficient risk assessment, and ------------------------------------------------------------------------------\ -- Page 5 177the damaging evidence within its own internal files suggesting suppression and misrepresentation of the risk information in its possession, that led to the erosion of public trust in the company. The Scientific Support for Dow Corning Dow Corning has steadfastly maintained that its silicone implant products did not pose risks of the kind which led judges and juries to award large settlements to the alleged victims. Despite claims brought by plaintiffs in these court cases that the company had clear scientific evidence of various systemic health risks such as cancer, autoimmune disease, and connective tissue disease which it suppressed or falsified in the regulatory process, Dow Corning argues that it did not have significant scientific evidence of any of these risks, and moreover that it had conducted sufficient research to warrant its conclusion that its products were safe. As time goes by, and additional studies of the systemic effects of silicone implants are reported, Dow Corning appears to be more and more vindicated in its claims that the risks of its product have been grossly overestimated and that the trial settlements were wrongly imposed upon the company. The scientific attack against the courts, lawyers, and plaintiffs’ groups has been led by the editor of the New England Journal of Medicine (NEJM), Dr Marcia Angell. Soon after the controversy broke in 1994, the NEJM published the first major epidemiological study of breast implant patients. This eight-year ------------------------------------------------------------------------------\ -- Page 6 178retrospective study of 749 women who had received breast implants at the Mayo Clinic found no significant differences in the incidence of connective tissue and other diseases among these women than among a non-implant control group twice the size.7In an editorial accompanying the publication of the study, Angell wrote that the study showed the decision of the FDA to remove silicone implants from the market in 1992 to be “overly paternalistic and unnecessarily alarming.” She also claimed that the FDA decision, which was based on the fact that the manufacturers “had not fulfilled their legal responsibility to collect data on the question” (not because implants were known to pose a risk), was construed by the public as an indictment of the implants. Frightening stories of autoimmune and connective-tissue diseases swept through the public and were, she said, “reified by repetition.... The accumulated weight of anecdotes was taken by judges and juries as tantamount to proof of causation.”8Angell pursued this argument in a 1996 book, Science on Trial,9in which she reported additional studies strongly corroborating the Mayo Clinic findings.10Angell argues that this story shows that the standard of scientific proof in the litigation of tort claims should be changed. In her view only scientific evidence based on a “factual standard” (i.e., published in peer-reviewed scientific journals) should be admitted as “expert testimony.” However, the U. S. Supreme Court earlier had considered and firmly rejected this demanding “factual standard” in a 1993 case, Daubert v. Merrell Dow Pharmaceuticals, Inc.11Instead, the court in Daubert empowered judges to make ------------------------------------------------------------------------------\ -- Page 7 179their own determinations about the scientific credibility of expert witnesses. Angell argues that such a legal standard permits the courts to base decisions upon scientifically unreliable foundations and this, in her opinion, was clearly what happened in the breast implant cases. Although some of the media commentary initially reinforced the allegations against Dow Corning and contributed to the public perception of the extensive risks associated with breast implants, in the wake of the evidence from the scientific studies the media interpretation also shifted dramatically. Stories with titles such as “The Great American Breast Implant Hoax,”12“A Confederacy of Boobs,”13and “Lawyers From Hell,”14appeared in major American magazines. Newspapers carried headlines such as “Dow Corning and the Courts: A Case of Justice or Total Travesty?”15“Why, to Science, the Law’s An Ass,” and “Can Science Free Women and Dow Corning?”16On 17 August 1995, the ABC show, Nightline, expressed a mea culpa for all the media with the comment that “it seemed we had it all wrong.”17As a result of the growing consensus among in the scientific and journalistic community, even the widespread view among business ethicists that Dow Corning had acted unethically has undergone revision.18The company has undertaken a vigorous public relations campaign to restore its image, which appears to be meeting with a great deal of success. The many groups who represent the alleged victims of silicone breast implants, led by the lawyers who so successfully managed the lawsuits, have responded with complaints about ------------------------------------------------------------------------------\ -- Page 8 180the way the company is spending “their” money to restore its image after a bankruptcy declaration, and have claimed that Dow Corning has in fact used millions of dollars to “buy” the scientific studies that fail to find significant systemic health risks. The company has admitted to having funded several of these studies, but points out that the funding of more research is precisely what its critics have demanded and adds that the research was carried out at respected, independent scientific research centres. The lawyers and victims’ groups have also pointed out that even these most recent studies have failed to rule out the possibility of significant risk for the systemic complications they believe are caused by breast implants. For example, the Mayo Clinic study involved too small a sample to rule out as much as a three-fold increase in the risk. One of the recent major studies did find a slight increase in reports of connective tissue disease among women with breast implants.19The most recent scientific review of all the epidemiological studies found that, while none has indicated a greatly increased rate of well-defined connective tissue disease or breast cancer in women with silicone breast implants, none has ruled out a moderately increased risk for these diseases either. This meta-analysis concluded: “Information is insufficient to adequately advise women who currently have or are seeking to obtain breast implants about the overall risk of these devices.”20Thus, the most salient aspect of the science for these non-scientific groups is not the fact that the risks appear low, but that this assessment itself if fraught with significant uncertainty. ------------------------------------------------------------------------------\ -- Page 9 181Dow Corning’s Assessment and Management of the Risks A. The Alleged Systemic Health Risks Dow Corning began producing silicone-filled breast implants in the early 1960s. The product was hailed as a major advance on the original method of direct silicone injection into the breast, since the silicone was contained in a protective pouch designed to isolate it from body tissue, dramatically decreasing the risk of adverse effects from silicone migration. The implants were introduced to the North American market years before the U.S. government enacted the Medical Devices Amendment to the Federal Food, Drug and Cosmetic Act in 1976, giving the FDA the authority to review and approve the safety and effectiveness data of new medical devices. Because silicone breast implants had been on the market for almost fifteen years by that time, they were " grandfathered.” This meant that no safety and effectiveness data on the implants were necessary unless and until the FDA requested them. Nevertheless, Dow Corning undertook to conduct and sponsor research on the potential health effects of both the silicone itself and breast implants. Included among these were toxicological studies of the effects of silicone and implants on laboratory animals, including whether silicone was “biologically inert.” Some of these studies suggested that the silicone might not be as biologically inert as first assumed, and that implants could produce inflammation and other responses that are consistent with immune response. Others suggested that silicone could enter the immune system of rats and mice ------------------------------------------------------------------------------\ -- Page 10 182and that these animals could develop sarcomas in response to injected silicone.21After the 1984 Stern lawsuit, Dow Corning had informed surgeons to whom they sold the implants of “reports of suspected immunological responses,” but the company also added the following evaluation: “A review of the published experimental findings and clinical experience shows that convincing evidence does not exist to support a causal relationship between exposure to silicone materials and ... rheumatic and connective tissue disorders.”22Clearly, Dow Corning scientists were convinced there was little, if any, risk of systemic health effects from their product. Because in their view the evidence of risk was meagre and public acceptance of the product during the first twenty years was high, and because the FDA did not (until 1988) request any safety studies from the industry, Dow Corning saw no need to conduct extensive risk research. Nor did the company think it necessary to make available the study results it did have to either the final consumers of the product or to the FDA. The company considered the initial studies it had conducted or sponsored to have failed to establish any scientifically significant evidence of systemic health effects. Even though some toxicological studies were consistent with that possibility, the observed effects were attributed to other factors. Thus the recognized uncertainties in the toxicological studies led to a decision to discount the potential risks rather than a decision to conduct further research. This decision was supported by existing, though minimal, ------------------------------------------------------------------------------\ -- Page 11 183epidemiological evidence, which gave no indication of systemic health risks associated with the silicone implant. Dow Corning faced a situation fairly typical for health risk assessments, where the toxicology indicates some risk (usually in animal studies) -- in the sense of potential harm to humans -- that is not confirmed by the available epidemiological evidence. Dow Corning also made the typical choice in these contexts — to prefer the indicators of low (or zero) risk to the other indicators of potentially significant risk. This choice underlay the decision not to conduct further studies and probably also the choice to withhold certain evidence from the regulators, the consumers, and the public. However, the failure to conduct more adequate risk research, especially given the growing allegations of systemic problems, is now seen even by some of the strongest defenders of breast implant safety as one of Dow Corning’s major failures. For example, even Marcia Angell admits that although the company “was right about the lack of evidence that the implants were dangerous... there was also little evidence that they were safe, because the manufacturers had not fulfilled their responsibility to look for it.”23This is a damning statement considering the source whence it comes. The decision not to conduct further research with silicone and implants became one of the major factors in persuading juries and the general public that Dow Corning had subjected women implant recipients to unacceptable risk. ------------------------------------------------------------------------------\ -- Page 12 184B. The Risks of “Local Complications” While the risks of systemic health effects from implants such as cancer or autoimmune and connective-tissue disease seemed to be remote during this period, there were other kinds of more immediate risks to women that were becoming clear to the company. Dow Corning knew in the early 1970s that the silicone could “bleed” or leak out of the envelopes in which it was enclosed. Although most leakage was thought to be contained in the capsule of scar tissue the body naturally formed around the foreign implant, there was evidence that it could migrate to surrounding tissue and to other areas of the body via the lymphatic system.24Most of the evidence of silicone bleed came not from the recipient women (who had no means of detecting the bleed itself), but from the surgeons who implanted them. The sales personnel who dealt directly with the plastic surgeons received a barrage of complaints from those surgeons that Dow Corning’s implants felt “oily” when they were removed from their packaging. This problem intensified in 1975 when, in response to pressure from other manufacturers whose product was considered to have a more “natural” shape and feel, Dow Corning developed an implant with a thinner envelope filled with silicone of thinner consistency, rushing the implants to market before adequate studies of their reliability could be carried out. Surgeons complained that the new implants were bleeding and even rupturing during implantation, and whole shipments were returned to the company.25Dow Corning’s response was not to ------------------------------------------------------------------------------\ -- Page 13 185remove the implants from the market, nor even to warn recipients of the risk, but to give misleading assurances about continuing safety studies.26Evidence of additional health risks with the implants emerged. Not only did the implants tend to rupture and spill during implantation, they were doing so after implantation as well. The result was that the breast would lose its shape and the contents would escape into the surrounding tissue, often producing high levels of trauma for the recipient, requiring surgical removal and sometimes re-implantation. The rate of rupture has been a matter of wide disagreement between the industry and its critics. For most of this period Dow Corning claimed it was in the vicinity of one to two per cent; early scientific estimates were over five per cent. Implant victims’ groups have claimed it to be higher than fifty percent, and have predicted that when enough time passes it will likely prove to be one hundred percent. In testimony before a congressional subcommittee in August 1995 FDA Commissioner Kessler stated: " Published studies to date suggest a rupture rate between 5 and 51 percent — an enormous range — and unfortunately, we do not know with any confidence where within that range the real rupture rate lies. " He also cited two studies indicating that the risk of rupture increases as the implants age. A published 1996 study by the FDA also reports that the rupture rate is still unknown, but clearly increases with age. The National Breast Implant Task Force claims that in a meeting in September, 1995 FDA officials informed them that its MedWatch reporting system indicated a fifty percent rupture rate. ------------------------------------------------------------------------------\ -- Page 14 186These high rupture rate estimates appear to be based upon studies done among women who report complications with their implants, and they may not accurately reflect the rupture rate among all implanted women. One of the problems in determining the exact rate was due to the fact that if the surrounding scar tissue capsule did not break, most of the silicone would be retained, and the rupture would not be noticed or reported. One study of women with implants who had mammograms showed that five percent had unnoticed ruptures.27Recent scientific studies lend support to the higher figures in the ranges. One study of 300 women treated for implant problems at the University of Alabama found that 214 (71.3%) of them had disruption (actual rupture or severe silicone bleed or both) of one or both implants.28Despite evidence of significant rupture rates, Dow Corning nevertheless continued to advise women in its product promotional literature during the 1970s and 80s that they could expect the implants to last a “natural lifetime.”29Further, Dow Corning learned early on that a normal body reaction to the insertion of the implant, as with any foreign object, was the formation of a fibrous capsule (a kind of scar tissue) around it, called “capsular contracture.” This produced a hardening of the breast which led to other complications, such as chronic soreness and reduced sensitivity of the nipples. Dow Corning recommended a procedure to surgeons for post-operative amelioration of this problem. This “closed capsulotomy” procedure involved a forceful squeezing of ------------------------------------------------------------------------------\ -- Page 15 187the breast by hand in order to break up the scar tissue and soften the breast — until the capsule formed again, which it usually did. Often the procedure was only partially successful, leaving the breast malformed. But more importantly, the procedure regularly produced an even worse result — the rupture of the implant itself, spilling its silicone contents into the surrounding tissue. By 1980 the company included in the package a warning to surgeons about this risk.30However, no similar warning was given to the women who received the implants. Between 1985 and 1995 the FDA received over 91,000 adverse reaction reports associated with silicone breast implants.31These reports included cases of leaking and rupturing as well as of the painful hardening, deformation, and desensitization of the breasts, which are now widely recognized and uncontested on all sides, including scientists and the industry. But they included as well claims of adverse effects still not proven to be linked to them. However, it was not the risks of these “local complications,” but rather those of the systemic diseases of the immune system and connective tissue, that courts used to justify the huge damages awarded to the plaintiffs who sued Dow Corning. Dow Corning’s Risk Communication Dow Corning argues that the storm of criticism the company received for not informing patients or the public about the known complications of breast implants is without merit. It has steadfastly maintained that it honestly and ------------------------------------------------------------------------------\ -- Page 16 188forthrightly communicated the risks of its implants to the appropriate stakeholders as it became aware of those risks. The appropriate stakeholders, according to Dow Corning managers, were primarily the surgeons who were the direct customers of the company’s product, and not the women who were the recipients of the implants and the bearers of the risks. The company argued that, like most medical device manufacturers, it relied on patient information being conveyed through physicians, and “physicians strongly maintained that direct communication by the company to patients was inappropriate and potentially interfered with the doctor/patient eelationship.”32Further, as the company’s health care business manager put it to a reporter who questioned the company’s view of disclosure: “We don’t know who the patients are.”33If patients agreed to be fitted with silicone breast implants without being fully informed of the known complications, it was Quote Link to comment Share on other sites More sharing options...
