Rapid Health Technology Assessment of Oncotype DX in Patients with Early-Stage Breast Cancer
Authors
Abstract:
Introduction: Breast cancer is the most common cancer in women. Patients are treated with chemotherapy initially, and if not chemically treated, the risk of recurrence of the disease increases yearly. Therefore, methods for identifying patients for whom chemotherapy would be most beneficial are very important. The Oncotype DX test is a prognostic assay that predicts the likelihood of breast cancer recurrence as well as the effectiveness of chemotherapy. Because of the novelty and the high cost of this test, the current study aims to determine its effectiveness and economic effects. Methods: This study, based on rapid health technology assessment, explored the effectiveness and economic consequences of Oncotype DX compared with alternative methods in breast cancer patients. PubMed, Scopus, Web of Science, and Cochrane databases were searched, and only studies about the use of the Oncotype DX test in breast cancer were included. Results: The results of the 32 relevant studies showed that the difference in outcomes was negligible across Oncotype DX and other gene expression profiling tests, but these differences were significant compared with standard treatment. Also, Oncotype DX testing would be cost-saving when used for patients under chemotherapy. However, using this test for all patients may not be cost-saving depending on the number of patients who switch from hormone therapy to chemotherapy and vice versa. Conclusion: Although the results of this study are helpful for policymakers and therapists, it is better to make decisions based on the results of effectiveness and cost in Iran.

Association Between Oncotype DX Recurrence Score and Clinicopathological Variables in Breast Cancer Patients
Introduction: Breast cancer is the most common cancer and the leading cause of cancer-related death in women. Clinicopathological variables are important factors in deciding on breast cancer treatment. This study evaluated the association between the recurrence score generated by the Oncotype DX® 21-gene assay and classic clinicopathological variables. Methods: A single-institution retrospect...
full textThe use of automated Ki67 analysis to predict Oncotype DX risk-of-recurrence categories in early-stage breast cancer
Ki67 is a commonly used marker of cancer cell proliferation, and has significant prognostic value in breast cancer. In spite of its clinical importance, assessment of Ki67 remains a challenge, as current manual scoring methods have high inter- and intra-user variability. A major reason for this variability is selection bias, in that different observers will score different regions of the same t...

This retrospective study evaluated the impact of intermediate Recurrence Score(®) results on adjuvant treatment decisions in estrogen receptor-positive (ER+) early invasive breast cancer, comparing treatment recommendations pre-testing with actual treatments received post-testing. Of the 111 patients included in the analysis, 78 (70.3%) had hormonal therapy (HT) and 33 (29.7%) had chemohormonal...
full textEffect of Oncotype DX colon cancer test results on treatment recommendations in patients with stage II colon cancer: Preliminary results.
398 Background: The Oncotype DX Colon Cancer Recurrence Score (RS) has been clinically validated as an independent predictor of individual recurrence risk in stage II colon cancer patients following surgery. As a result, physicians have been ordering the Oncotype DX assay for stage II colon cancer patients since January 2010, yet no data exist on the assay's impact on adjuvant treatment plannin...
full textUse of Oncotype DX in Women with Node-Positive Breast Cancer
Women with early stage breast cancer frequently receive adjuvant chemotherapy to prevent recurrence; however, not all patients benefit. Recently, gene expression marker panels, such as Oncotype DX, that may better predict risk of breast cancer recurrence have become commercially available and are being used to guide treatment decisions. Oncotype DX analyzes the expression of 21 genes within a t...
