The know error® system for breast biopsies is being showcased at the Annual Meeting of the American Society of Breast Surgeons. The meeting will be held April 27- May 1, 2011 at the Marriott Wardman Park in Washington, DC. Look for us at Booth #429. For more information on this meeting, click here.

The know error® system for breast biopsies, introduced in the summer of 2010 by Diagnostic ID, LLC, provides an effective way to establish specimen provenance. Through the use of DNA Specimen Provenance Assignment (DSPA) and bar code technology, the know error® system brings new levels of safety and accuracy to the biopsy evaluation process.

This innovative system dramatically reduces the incidence of Specimen Provenance Complications (SPC) which may arise due to instances of specimen transposition, foreign cell contamination, and patient misidentification that occur in clinical or anatomical pathology. By performing DNA testing of biopsy tissue samples PRIOR to any treatment taking place, the know error® system virtually eliminates any adverse patient outcomes due to SPC.

On July 20, 2010, a story in The Vancouver Sun revealed a case where an accidental biopsy mix up resulted in an unnecessary lumpectomy for one woman and a 10 week delay in treatment for another.

As with similar cases documented in this blog, the mix up was discovered by a pathologist performing routine post-surgical tests that revealed no cancer in the patient's tissue samples.  The report states, "...DNA tests confirmed on July 16 that the woman's initial biopsy...was accidentally switched with a similar biopsy from another woman."  This type of mix up is just one of many types of Specimen Provenance Complications (SPC) that can lead to diagnostic mistakes.  Other examples of SPC are specimen transposition and foreign cell contamination. 

Launched in the summer of 2010, the know error® system for breast biopsies brings new levels of safety and accuracy to the biopsy evaluation process.  Through the use of DNA Specimen Provenance Assignment (DSPA) and bar code technology, this innovative system dramatically reduces the incidence of SPC so that diagnostic mistakes are minimized. 

While the DNA tests in this case confirmed the mix up, this was unfortunately AFTER the unnecessary surgery and delay in treatment.  The know error® system performs DSPA of biopsy tissue samples PRIOR to any treatment taking place and virtually eliminates diagnostic mistakes due to SPC.  This allows both patient and physician to proceed confidently with treatment options based on the patient's biopsy results.

Recent posts discussing the cases of Darrie Eason, Scott Aprile and "Kim," a woman from Korea, revealed three similar. Each involved some form of patient misidentification that resulted in a cancer-free patient undergoing unnecessary breast removal surgery. Media coverage of these types of cases tends to focus on the patient who received some form of unnecessary treatment. While tragic for these patients, the reports seem to overlook a second and possibly more tragic victim - the patient WITH cancer who received delayed treatment or worse, no treatment at all.

On August 12, 2009, an article published in The Korea Times revealed that two of Korea's top hospitals had been held liable in the case of a cancer-free woman, referred to as "Kim," who mistakenly had part of her right breast removed. In 2005, a tumor was found in Kim's right breast during a routine check-up. She had an ultrasound and biopsy to further examine the tumor; however, as the tests were being evaluated, the hospital mistakenly switched her chart with that of another patient. Based on the another patient's chart, she was diagnosed with cancer and it was recommended that she have part of her right breast removed. Upon seeking a second opinion, some simple tests were performed, but there was no second biopsy and the cancer diagnosis was confirmed based on the switched biopsy results.  

Recent posts have discussed several cases where medical mix-ups have resulted in unnecessary cancer removal surgeries. One case was that of Scott Aprile, a 28 year old personal trainer, who had his breast tissue and several lymph nodes removed after his lab results were switched with another patient's. Another case discussed a 32 year old woman from Melbourne, Australia, who underwent a radical hysterectomy after her biopsy sample had been contaminated with tissue from a patient who did have cancer. In each of these cases, both patients underwent unnecessary surgeries as well as the immeasurable pain and suffering that go along with a cancer diagnosis. But, they also had another thing in common - they both survived.

In early 2008, a similar lab mix up resulted in the death of a young New York woman.  She had been mistakenly diagnosed with breast cancer and decided to move ahead with treatment quickly since breast cancer ran in her family. She opted for a double mastectomy in conjunction with reconstructive surgery. The day after the surgery she died due to complications from the surgery. As with the two cases above, post surgical tests revealed there was no cancer in the first place. The hospital also made similar claims as those made in the other two cases, i.e., they had taken steps "to ensure that such an event [would] not occur in the future." 

While it is unknown what specific steps have been taken or will be taken by these hospitals, it is known that these types of Specimen Provenance Complications (SPC) cannot be prevented through procedural improvements alone.  (Read more on this here.)  One way to truly prevent SPCs is to utilize DNA matching technology to confirm the positive biopsy tissue belongs to the patient prior to beginning any treatment plans or surgery.

Through the use of DNA Specimen Provenance Assignment (DSPA) and bar code technology, the know error®  system brings new levels of safety and accuracy to the biopsy evaluation process. This innovative system dramatically reduces the incidence of SPCs enhancing patient safety and diagnostic accuracy. By performing DNA testing prior to treatment, the know error® system virtually eliminates diagnostic mistakes due to SPC.
