Recrudescence of Traumatic Cancer Claims

In 1991, Peter Huber, discussing traumatic cancer claims, wrote:

“After years of floundering in the junk science morass of traumatic cancer, judges slowly abandoned sequence-of-events logic, turned away from the sympathetic speculations of family doctors, and struggled on to the higher and firmer ground of epidemiology and medical science.  Eventually, the change of heart among appellate judges was communicated back down to trial judges and worker’s compensation boards, and traumatic cancer went into almost complete remission.”

Peter W. Huber, Galileo’s Revenge: Junk Science in the Courtroom 55-56 (1991).

With the advent of Daubert and meaningful gatekeeping of expert witness opinion testimony, the traumatic cancer claims did recede. For a while. Plaintiffs’ counsel, and stalwart opponent of epistemic standards for scientific claims in court, Kenneth Chesebro attacked Huber’s précis of the traumatic cancer law and science. Kenneth J. Chesebro, “Galileo’s Retort: Peter Huber’s Junk Scholarship,” 42 Am. Univ. L. Rev. 1637 (1993). Defenses of the dubious science continue to appear, although mostly in non-peer-reviewed publications.[1]

One of the more disturbing implications of the West Virginia Supreme Court’s decision in Harris v. CSX Transportation, Inc., 232 W.Va. 617, 753 S.E.2d 275 (2013), was the Court’s reliance upon its own, recent approval of traumatic cancer claims.  The Harris Court cited, with approval, a 2002 traumatic cancer case, State ex rel. Wiseman v. Henning, 212 W.Va. 128, 569 S.E.2d 204 (2002).  The Wiseman case involved a specious claim that a traumatic rib injury caused multiple myeloma, a claim at odds with scientific method and observation.  The West Virginia Supreme Court blinked at the challenge to the physician expert witness who advanced the causal claim in Wiseman; and in Harris, the Court made clear that blinking is what trial courts should do when confronted with methodological challenges to far-fetched causal opinions.

A couple of years ago, the New York Times ran an article about traumatic cancer. C. Claiborne Ray, “Injury and Insult” (Nov. 5, 2012), responding to the question “Is it possible for cancer to develop as a result of an injury?” Here is how Times science reporter responded:

A.It’s a common myth that injuries can cause cancer,” the American Cancer Society says on its Web site. Until the 1920s, some doctors believed trauma did cause cancer, “despite the failure of injury to cause cancer in experimental animals.” But most medical authorities, including the cancer society and the National Cancer Institute, see no such link. The more likely explanation, the society suggests, is that a visit to the doctor for an injury could lead to finding an existing cancer.

Other possibilities are that scar tissue from an old trauma could look like a cancerous lesion and that an injured breast or limb would be more closely watched for cancer to develop.

Ms. Ray went on to note a published study, in which would-be myth-busters presented observational data purportedly showing a relationship between physical injury and subsequent breast cancer.  The paper cited by Ms. Ray was a report on a small case-control study done by investigators at the Department of Geography, Lancaster University. See Jan Rigby, et al., “Can physical trauma cause breast cancer?” 11 Eur. J. Cancer. Prev. 307 (2002). The study consisted of 67 breast cancer cases and 134 controls, matched on age, family history, age of menarche, parity, age at first birth, and menopausal status.

Not surprisingly, considering its small size, the Rigby study reported no statistically significant differences for several factors known to be associated with breast cancer: social class, education, residence, smoking and alcohol consumption.  Although lacking power to detect differences of known risk factors, this study turned up a large, statistically significant association between physical trauma and breast cancer:

“Women with breast carcinoma were more likely to report physical trauma to the breast in the previous 5 years than were the controls (odds ratio (OR) 3.3, 95% confidence interval (CI) 1.3-10.8, P < 0.0001).”

* * * * *

“More likely to [self-]report” hardly implies causation, but the authors jumped not only to a causal explanation but to a causal conclusion:

* * * * *

“In conclusion, recall bias is an unlikely explanation for these results in view of the nature and severity of physical trauma. Models of epithelial cell generation indicate that a causal link between physical trauma and cancer is plausible. A latent interval between cancer onset and presentation of under 5 years is also plausible. The most likely explanation of the findings is that physical trauma can cause breast cancer.”

Rigby at 307.

The Rigby study is a valuable demonstration of how malleable researchers can be in discovering plausible explanations for their data.  The authors fail to discuss the natural history of breast carcinoma, such as tumor doubling time, which would make their five-year window decidedly implausible.  The Rigby paper also demonstrates how strident researchers can be in claiming that they have produced a study that has eliminated bias in observational research, when they have barely scratched the surface of bias or confounding. Magical thinking is not the exclusive domain of lawyers.

Until reading the Harris and Wiseman cases, I had thought that the legal system had graduated from the “mythology” of traumatic cancer cases.[2]  To be sure, in the past, any number of physicians have supported traumatic cancer claims, in print and in the courtroom.[3] Some authors attempted to put some rational limits on the extent of the traumatic cancer claims.[4] By 1947, at least, the trauma theory was criticized in leading texts.[5]  In 1974, the Mayo Clinic published a review that emphasized the lack of experimental evidence to support the claim that uncomplicated trauma causes cancer.[6] The law review literature attempted to make sense of the compensation-frenzied courts, without much success.[7]

Many cases from most jurisdictions have approved traumatic cancer claims.  Some are set out below. Some courts heroically resisted the pro-compensation Zeitgeist, usually on case-specific evidentiary issues.[8]

In New York, judges seem to be well aware that post hoc ergo propter hoc is a fallacy.  Cassano v. Hagstrom, 5 N.Y.2d 643, 159 N.E.2d 348, 187 N.Y.S.2d 1 (1959) (affirming dismissal of case based because of plaintiffs’ attempt to use fallacious reasoning in the form of  “post hoc ergo propter hoc”); Holzberg v. Flower & Fifth Ave. Hosps., 39 AD 2d 526 (N.Y. 1st Dep’t 1972). Still, the New York courts struggled with traumatic cancer claims, and appeared to oscillate wildly without clear guidance on whether or to what extent the courts could reject specious claiming supported by speculative or unreliable expert witness opinion testimony.[9] Given the current hostility to gatekeeping of expert witness opinion, a recrudescence of traumatic cancer claims is likely.
