When is adjuvant chemotherapy used?
Adjuvant therapy is often used after primary treatments, such as surgery, to lessen the chance of your cancer coming back. Even if your surgery was successful at removing all visible cancer, microscopic bits of cancer sometimes remain and are undetectable with current methods.

Background. Tamoxifen is standard adjuvant treatment for postmenopausal women with hormone-receptor-positive breast cancer. We assessed the benefit of adding chemotherapy to adjuvant tamoxifen and whether tamoxifen should be given concurrently or after chemotherapy.Dec 11, 2009
When is targeted therapy used?
Targeted therapy is a cancer treatment that uses drugs to target specific genes and proteins that are involved in the growth and survival of cancer cells. Targeted therapy can affect the tissue environment that helps a cancer grow and survive or it can target cells related to cancer growth, like blood vessel cells.

Can cancer spread after surgery?
If the cancer is at a very early stage — before it has had time to spread — then the chance of cancer recurring after surgery may be very small . Adjuvant therapy may offer little benefit in this case. But if a cancer is at a later stage or it has spread to nearby lymph nodes, adjuvant therapy may be more beneficial.

What is the use of DNA microarrays in breast cancer?
The National Comprehensive Cancer Network (NCCN) clinical guidelines for breast cancer state that the use of DNA microarray technologies to characterize breast cancer has allowed for development of classifications of breast cancer by gene expression profile. Five major subtypes of breast cancer have been identified by DNA microarray gene expression profiling. In retrospective analyses, these gene expression subtypes are associated with differing relapse-free survival and overall survival (OS). The following tests are reviewed by NCCN as appropriate for use to provide prognostic and therapy predictive information for node negative breast cancer that complements tumor, node and metastasis staging. They note that these tests can provide additional prognostic information in patients with 1-3 positive nodes, but their ability to predict chemotherapy benefit is this group is still unknown. They based their opinion in part on the review of Sestak, et al. (2018) who provided a secondary analysis of data obtained from the Anastrozole or Tamoxifen Alone or Combined randomized clinical trial, comparing 5-year treatment with anastrozole vs tamoxifen with 10-year follow-up data. The objective was to compare the prognostic value of Oncotype Dx recurrence score, PAM50-based Prosigna risk of recurrence (ROR), Breast Cancer Index (BCI), EndoPredict (EPclin), Clinical Treatment Score, and 4-marker immunohistochemical score to the Clinical Treatment Score (nodal status, tumor size, grade, age, and endocrine treatment) for distant recurrence for 0 to 10 years and 5 to 10 years after diagnosis. The analysis included 774 post-menopausal women with estrogen positive, HER2 negative disease. Five hundred and ninety one had node-negative disease. All genomic signature tests provided significantly more information that the clinical treatment score, the recurrence score and the 4 marker immunohistochemical score alone. The most valuable tests were the PAM 50 and BCI. In the 183 patients with 1-3 positive nodes, there was limited information provided by the molecular tests, and BCI and Endopredict provided the most value. The authors concluded that the data provided by molecular testing could help oncologists and patients consider chemotherapy or extended endocrine testing (NCCN, Breast 2020b).
What is the ASCO clinical practice guideline update?
Andre et al. (2019) published the recent ASCO Clinical Practice Guideline Update for the use of biomarkers to guide adjuvant therapy for early-stage breast cancer. The update was created by an expert panel that reviewed the results of TAILORx trial along with other published literature on the Oncotype DX assay to assess for evidence of clinical utility. The updated recommendations only refer to patients with hormone receptor positive, HER2 not overexpressed, axillary node-negative early breast cancer and include the following:
What is CGH in genomics?
Comparative Genome Hybridization (CGH): CGH is a technology that can be used for the detection of genomic copy number variations (CNVs). Tests can use a variety of probes or single nucleotide polymorphisms (SNPS) to provide copy number and gene differentiating information. All platforms share in common that tumor (patient) and reference DNA are labelled with dyes or fluorescing probes and hybridized on the array, and a scanner measures differences in intensity between the probes, and the data is expressed as having greater or less intensity than the reference DNA (Cooley et al; 2013).
What is the DX test for breast cancer?
Oncotype Dx Breast (Oncotype DX; Genomic Health, Redwood City, CA) is a test that analyzes the expression of a panel of 21 genes within a tumor to determine a “Recurrence Score” which may correspond to a likelihood of breast cancer recurrence within 10 years. The test was initially developed for women with early-stage invasive breast cancer with ER+ cancers that are lymph node-negative, and subsequently evidence was gathered on individuals with up to 3 ipsilateral nodes positive. These individuals are typically treated with anti-hormonal therapy, such as tamoxifen or aromatase inhibitors, and Oncotype Dx® can help determine if chemotherapy should be added to the treatment regimen (Evaluation of Genomic Applications in Practice and Prevention (EGAPP) Working Group, 2016).
What is the PAM 50?
PAM- 50, also known as Prosigna® by (NanoString Technologies (Seattle, WA)is a breast cancer prognostic assay that provides a risk category and numerical score to assess an individual’s risk of distant recurrence of disease at 10 years in postmenopausal women with node-negative (Stage I or II) or node-positive (Stage II), hormone receptor-positive breast cancer . The Prosigna assay measures expression levels of 50 genes using formalin-fixed paraffin-embedded (FFPE) breast tumor tissue diagnosed as invasive breast carcinoma. The assay is not intended for individuals with 4 or more positive nodes (Gnant et al., 2013; Parker et al., 2009).
What is mammaprint test?
MammaPrint® (Agendia, Amsterdam, The Netherlands) is a 70-gene expression test to assess breast cancer distant recurrence risk. The assay analyzes tumor tissue (fresh, frozen or formalin-fixed paraffin-embedded) for expression of 70 genes assumed to be important in cancer metastasis. Based on the test results, Mammaprint may assist individuals considering adjuvant treatments. Individuals are assigned either a low risk or a high risk for a distant recurrence. The risk category may be taken into consideration for treatment options.
What is endopredict PCR?
EndoPredict (Sividon Diagnostics (acquired by Myriad [Salt Lake City, UT] in 2016) is a 12-gene real-time RT-PCR that includes eight disease-relevant genes BIRC5 , UBE2C, DHCR7, RBBP8, IL6ST, AZGP1, MGP and STC2 are compared to three RNA normalization genes (CALM2, OAZ1 and RPL37A) and to one DNA reference gene (HBB).
