What is adjuvant or neoadjuvant therapy?
This type of adjuvant therapy can also decrease the chance of the cancer coming back, and it's often used to make the primary treatment — such as an operation or radiation treatment — easier or more effective. Adjuvant or neoadjuvant therapy can cause significant side effects, and these treatments don't benefit everyone.
Is adjuvant therapy the same as chemotherapy?
Additional cancer treatment given after the primary treatment to lower the risk that the cancer will come back. Adjuvant therapy may include chemotherapy, radiation therapy, hormone therapy, targeted therapy, or biological therapy.
What is adjuvant chemotherapy for breast cancer?
Adjuvant chemotherapy refers to the use of cytotoxic chemotherapy after breast cancer surgery, administered with the goal of eradicating microscopic foci of cancer cells that, if untreated, could grow and recur as metastatic cancer.

What is adjuvant endocrine therapy?
Adjuvant endocrine therapy is a standard treatment for hormone receptor (HR)-positive, early-stage breast cancer. Tamoxifen, a selective estrogen receptor modulator (SERM), has been used for several decades in this setting. The benefits of adjuvant tamoxifen were shown in the first Early Breast Cancer Trialists' Collaborative Group (EBCTCG) ...
How long should I take tamoxifen after breast cancer?
The 2010 ASCO guidelines recommend that postmenopausal women with HR-positive breast cancer consider the use of an AI during adjuvant treatment, either as primary (initial) therapy, as sequential therapy (after 2 to 3 years of tamoxifen), or in the extended adjuvant setting (after 5 years of tamoxifen). [2] These guidelines state that the “optimal timing and duration of endocrine treatment remain unresolved,” although they recommend 5 years of an AI in the primary and extended adjuvant settings, and 5 years total endocrine therapy in the sequential setting. In absolute terms, the reduction in the risk of recurrence from AI-based therapy compared with tamoxifen is modest, less than 5%, through multiple years of follow-up, and the overall survival (OS) is equivalent in the primary and extended adjuvant trials. In two of the six sequential trials, there was a significant improvement in OS, although the absolute difference was small. Available data have not yet defined the optimal time for switching from tamoxifen to an AI. The guidelines recommend switching after 2 to 3 years of tamoxifen instead of after 5 years, although they do state that switching at 5 years is also supported by the available data.
Why is the combination arm of Anastrozole closed?
The combination arm was closed due to inferiority. With a median follow-up of 120 months, the primary endpoint of DFS was significantly longer with anastrozole. Anastrozole was also associated with a longer time to recurrence, longer time to distant recurrence, and decreased contralateral breast cancers.
What is ovarian suppression?
Ovarian suppression (OvS)/ovarian ablation (OA) can be used in the adjuvant treatment of premenopausal breast cancer. OA can be accomplished via surgery (oophorectomy) or radiation; OvS is achieved via medications (luteinizing hormone–releasing hormone [LHRH] agonists). The EBCTCG meta-analysis included nearly 8000 women younger than 50 years of age with ER-positive or ER-unknown disease. [12] For women who received OvS/OA, there was a significant decrease in both the 15-year probability of breast cancer recurrence (2 P < .00001) and mortality (2 P = .004) compared with those who received no ovarian treatment. Ovarian treatment had a smaller effect in the trials in which both groups received chemotherapy. There was no indication that the effects of OA differed from those of OvS.
Does hormonal therapy reduce recurrence?
While studies have found that adjuvant hormonal therapy for hormone-sensitive breast cancer dramatically reduces recurrence and mortality, adherence to medications is suboptimal. In a study of 8769 patients with stage I-III breast cancer diagnosed from 1996 to 2007, only 49% of the patients took adjuvant hormonal therapy for the full duration on an optimal schedule. [53] A recent study analyzing medical and pharmaceutical claims data from three national longitudinal databases found that adherence to adjuvant anastrozole therapy decreased from between 69% and 78% at year 1 to between 50% and 68% at year 3. [54] The success of AI treatment depends on adherence to the regimen. Thus, it is important for the oncologist to ask a patient about adherence. One nonjudgmental way of doing this is to ask how many pills the patient has missed in the last month, rather than asking if she has been taking her medication. Switching to another AI may be an alternative for women who are nonadherent because they are unable to tolerate the side effects of a particular AI.
Is tamoxifen good for breast cancer?
For many decades, tamoxifen has been the standard adjuvant endocrine treatment for HR-positive, early-stage breast cancer. For premenopausal women, it remains so. In premenopausal women, the role of ovarian suppression or ovarian ablation is not clear, and the results of studies examining these strategies in combination with tamoxifen or AIs-the SOFT and TEXT trials-are eagerly awaited.
What is the best treatment for breast cancer?

The longer treatment improved 5-year disease-free survival ...
Does longer duration of breast cancer treatment improve survival?
There is no evidence yet that the longer duration of therapy improves overall survival, but in a press briefing at the ASCO meeting Dr. Goss called the reduced risk of contralateral breast cancer a “major benefit.”.
Does letrozole help with breast cancer?
The trial, called MA.17, also showed that extended letrozole therapy reduced the risk of developing contralateral breast cancer. However, even with successful initial treatment, women with HR-positive early-stage breast cancer continue to have a risk of their disease returning. Some women can have recurrences even two decades after their initial ...
