Personalized Medicine and Genomics

An emerging model of health care delivery that uses genetic information to customize a patient’s treatment.

International Comparison of Frameworks for Valuing Drugs

Mar. 1, 2017

“Pay more for drugs that do more.” Although few would argue with the concept of paying for value, the mechanism for doing so has thus far eluded our multi-payer, market-based system. The Gant Precision Cancer Medicine Consortium at the University of Pennsylvania looked past US borders to learn about mechanisms in other countries, in its quest to recommend sustainable frameworks for valuing precision cancer drugs.

It Takes a Consortium: New Group Tackles Precision Cancer Medicine

Oct. 27, 2016

A new multidisciplinary consortium of more than 20 experts and stakeholders has come together at Penn to address the promise and challenges of precision cancer medicine. Through multiple conference calls culminating in a conference in May 2017, the group will tackle the hard questions that precision medicine raises for patients, providers, and payers. This is the first in a series of posts on the consortium’s work.

Adjuvant Chemotherapy Use and Health Care Costs After Introduction of Genomic Testing in Breast Cancer

Research Brief
Feb. 3, 2016

The promise of personalized genomic testing is that it can reduce unnecessary care and costs by predicting which patients are most likely to benefit from a treatment. In this study of actual treatment patterns, LDI Senior Fellows Andrew Epstein and Peter Groeneveld and colleagues investigate how genomic testing of women with early-stage breast cancer affects subsequent chemotherapy use and medical spending in the year after diagnosis. After surgery, women with early-stage breast cancer face the decision of whether to undergo expensive and potentially toxic chemotherapy to prevent recurrence, although most will not have a recurrence. The 21-gene recurrence score test (RS) was developed in 2004 to predict this risk, and its use in clinical medicine is increasing. Epstein and Groeneveld find that genomic testing is associated with decreased use of chemotherapy and lower costs in younger patients, and slightly increased use of chemotherapy and higher costs in older patients. Genomic testing in actual practice may “rule out” chemotherapy in younger women, and “rule in” chemotherapy in older women.

Using Genomic Information to Improve Public Health

Aug. 11, 2015
What exactly is precision medicine? When the human genome was sequenced more than a decade ago, it began a new era of medicine that is now known as precision medicine. Initially, it was called personalized medicine; however, the word “personalized” was replaced with “precision” because it caused confusion and was misinterpreted. The goal of precision medicine is not to develop preventions and treatments that are unique for each individual. The National Research Council defines precision medicine as a medical model that focuses on “identifying which approaches will be effective for which...

The FDA, 23andMe, And What We Really Want From Genetic Testing

Nov. 27, 2013

In a harshly worded letter released Monday, the Food and Drug Administration (FDA) ordered the company 23andMe to “immediately discontinue marketing” its saliva spit test (from which a consumer’s DNA is isolated) and personalized genome service until it provides the FDA with requested information on safety and effectiveness. I asked Reed Pyeritz, MD, PhD, a medical geneticist at Penn and former president of the American College of Medical Genetics, to comment on this development. He wrote:
