- Further demonstrates the test's ability to change clinical chemotherapy treatment decisions by more precisely identifying patients who will or will not benefit from chemotherapy hence targeting treatment more effectively
- Underscores the value of the test in both node negative (N0) and node positive (N+) disease
GENEVA, Oct. 22, 2018 /PRNewswire/ -- Results from two prospective decision impact studies1,2, presented at the ESMO 2018 Congress, October 19-23 in Munich, Germany, further support the utility of the Oncotype DX Breast Recurrence Score® test to optimise chemotherapy recommendations in patients with early-stage, hormone-receptor positive, HER-2 negative breast cancer with or without lymph node involvement. These new results add to the body of data supporting the Oncotype DX test, which includes multiple validation studies demonstrating its unique ability to predict chemotherapy benefit along with prospective evidence in more than 70,000 patients both with N0 and N+ disease3-8, showing that the test accurately predicts clinical outcomes.
The first study1 presented at ESMO is research from Ireland assessing the impact of the Oncotype DX test on treatment decisions in routine clinical practice for early breast cancer patients whose disease has spread to the lymph nodes (one to three positive nodes). Overall, access to the test's results led to a reduction in physician perception of tumour chemo-sensitivity. From the 74 patients with Recurrence Score® results included in the analysis, the study found that in 64% of cases oncologists thought the test's result substantially changed treatment recommendations. In particular, testing with Oncotype DX led to a 27% reduction in chemotherapy recommendations.
"These new results strengthen published findings from our PlanB study and show the unique value of adding genomic information provided by the Oncotype DX test to better target chemotherapy. Oncotype DX identifies patients who can safely be spared chemotherapy toxicity and side effects. Furthermore, we have to be concerned about a relevant proportion of patients who seem to be undertreated if the risk of recurrence is evaluated using only traditional clinical parameters," said Prof. Ulrike Nitz, head of the breast cancer/senology unit at the Bethesda Hospital, Moenchengladbach, Germany. "The use of the Oncotype DX test allows us to tailor treatment plans more accurately to suit the needs of individuals, and to use resources more effectively."
Also presented at ESMO, results of another real-life, decision-impact study2 from France and Italy including both N0 and N+, early-stage breast cancer patients showed that treatment recommendations changed for 35% of patients included in the study based on Recurrence Score results, and that using the test to guide treatment decisions resulted in a relative net reduction in chemotherapy recommendations of 43%. These changes in treatment recommendations would be even greater in patients with N0 disease applying decision-making criteria (Recurrence Score groups) based on results from the recently published landmark TAILORx study.3
TAILORx - the largest randomised adjuvant breast cancer treatment trial ever conducted - definitively confirmed the value of the Oncotype DX test for precisely guiding adjuvant chemotherapy decisions in patients with early-stage, node-negative breast cancer. In particular, results demonstrate that the test provides definitive evidence about the magnitude of chemotherapy benefit based on prospective long-term patient follow up, identifying the vast majority of women who receive no substantial benefit from chemotherapy, as well as the important minority of women for whom chemotherapy can be life-saving. Thus, the test can greatly reduce both over- and undertreatment with chemotherapy.
This was recently acknowledged by Germany's health technology assessment body - the Institute for Quality and Efficiency in Health Care (IQWiG) - which concluded that only the Oncotype DX test has sufficient evidence to guide breast cancer adjuvant chemotherapy decisions based on the TAILORx study results.
Separately, the National Comprehensive Cancer Network (NCCN) recently updated their guidelines for invasive breast cancer chemotherapy treatment and categorised Oncotype DX as the only "preferred" test for chemotherapy treatment decision-making for patients with node-negative, early-stage breast cancer. In the updated NCCN guidelines, Oncotype DX continues to be distinguished as the only genomic test predictive of chemotherapy benefit.
"The momentum for genomic testing is building as healthcare systems across the world recognise its value to patients and society," said Torsten Hoof, Senior Vice President International, Genomic Health. "There is evidently a clear need for a personalised approach as part of routine decision-making – not just in Europe but globally, and we look forward to continuing to work with the relevant authorities to make the Oncotype DX test available to patients on a wider scale."
About early-stage breast cancer and the Oncotype DX test
Oncotype DX is the only genomic test validated for its ability to predict the likelihood of chemotherapy benefit as well as risk of recurrence in early-stage breast cancer. Breast cancer is the most common cancer in European women9 and affects many of them during their years dedicated to working and raising a family. While chemotherapy is routinely offered, research shows that only a minority of patients with early-stage breast cancer actually benefit from it.10,11
The Oncotype DX test is designed to facilitate personalised clinical decisions by providing information about the biology of an individual breast cancer, with the potential to deliver financial benefits for healthcare systems.
Healthcare systems across Europe are recognising the value of the test, which is incorporated in all major international clinical guidelines. Following assessment and recommendation by NICE, the Oncotype DX test is widely available to patients across the UK. In France, Oncotype DX is available through a funding mechanism for genomic tests. Other European countries where the test is reimbursed include Switzerland, Ireland, Greece and Spain.
