What is adjuvant chemotherapy?
So, adjuvant chemotherapy takes place after you’ve had first-line treatment, such as surgery to remove a cancerous tumor. The main goal of adjuvant chemotherapy is to lower the chance that the cancer will return, and to improve the outcome of first-line treatment. Sometimes cancer cells can be left behind after surgery.
How long does adjuvant chemotherapy take to work?
Adjuvant chemotherapy typically begins within three to five weeks of the surgical removal of the cancer and has different treatment lengths depending on the cancer. For breast cancer, the adjuvant chemotherapy is administered for three to nine months. In the case of colon cancer, treatment rarely last more than six months.
What is included in adjuvant treatment for breast cancer?
Adjuvant treatment may include local irradiation after mastectomy, systemic therapy with cytotoxic chemotherapy, or endocrine therapy. For the first time, a decrease was noted in breast cancer mortality in the United States and the United Kingdom, a welcome trend likely due to the use of adjuvant treatments.
What are the different types of adjuvant treatments?
Many different treatments may be administered as adjuvants. They may include adjuvant chemotherapy, radiation, immunotherapy, or targeted therapies. Adjuvant therapies are a common part of treatment plans for breast cancer, colon cancer, and lung cancer. 1
When is adjuvant chemotherapy used?
Adjuvant chemotherapy is administered after surgery to kill any remaining cancer cells with the goal of reducing the chances of recurrence.
When did chemotherapy start to be used as treatment?
The era of chemotherapy had begun. Metastatic cancer was first cured in 1956 when methotrexate was used to treat a rare tumor called choriocarcinoma. Over the years, chemotherapy drugs (chemo) have successfully treated many people with cancer.

Types of Adjuvant Therapy
Even after the successful removal of a cancerous tumor, cancer cells can remain either at that site or in other areas of the body where they’ve spread. Adjuvant therapy is any additional therapy you may undergo to reduce the risk of cancer returning after successful surgery or initial treatment.
Adjuvant Therapy Treatments
Many different treatments are used as adjuvant therapies. Depending on the type of cancer, these may be used as primary therapies.
Adjuvant Therapy Side Effects
Just like primary treatments, adjuvant cancer therapies come with side effects. The side effects of adjuvant therapy will vary based on the types of treatment and the doses being used.
Summary
Adjuvant therapy for cancer is a treatment done in addition to the treatment given to the primary tumor (such as surgery). It aims to kill any cancer cells remaining at the site or that have spread to other places in the body. Adjuvant therapy may be chemotherapy, immunotherapy, hormone therapy, targeted therapy, or radiation therapy.
A Word From Verywell
A cancer diagnosis is hard enough on its own, but there are additional challenges when faced with a whole new vocabulary and multiple treatment options. Adjuvant therapies can cause side effects, cost you more, and require additional visits to the doctor or clinic. But they can also reduce the risk of cancer returning or prolong your life.
Frequently Asked Questions
Adjunct therapies are used alongside the primary treatment method to make the primary treatment (such as surgery or radiation) work better. 5
What is neoadjuvant chemotherapy?
Neoadjuvant chemotherapy offers the potential to assess the response of the primary lesion and for tumor downstaging, though it may lead to a discordance between clinical and pathologic staging and delayed definitive local therapy.
Can bladder cancer be cured with surgery?
High-risk patients who might benefit the most could then be selected to receive adjuvant chemotherapy. Although the majority of patients with pT2N0 bladder cancer may be cured by surgery alone, only a minority of patients with pT3 or higher remain cancer free.
Is adjuvant chemotherapy better than neoadjuvant?
Adjuvant chemotherapy allows for pathologic staging and avoids delay in potentially curative local therapy. No randomized trials have compared neoadjuvant to adjuvant chemotherapy in patients undergoing definitive local therapy. Although some trials have suggested a survival advantage for neoadjuvant chemotherapy, there have been no contemporary studies supporting such a benefit with adjuvant chemotherapy.
Does neoadjuvant chemotherapy improve survival?
Although neoadjuvant chemotherapy seems to improve survival rates only marginally, it certainly has a significant impact in terms of tumor downstaging. Major responses (defined as transition from invasive disease to T0, CIS, Ta, or T1) occurred in approximately 40% of patients.
Is doxorubicin a monotherapy?
Though doxorubicin is the most common chemotherapeutic for thy roid cancer, monotherapy results are poor, and only 17% of cases achieve partial remission. However, when doxorubicin is combined with cisplatin, there is higher therapeutic activity and more complete responses, with 30% of patients responding successfully.
Is doxorubicin a radiation sensitizer?
Chemotherapy. Adjuvant chemotherapy is not useful to manage differentiated thyroid cancer. Doxorubicin may be a radiation sensitizer in some thyroid tumors and has been considered for locally advanced disease while EBRT is being administered.
What is adjuvant treatment?
Adjuvant treatment is the administration of additional therapy after primary surgery to kill or inhibit micrometastases. Primary surgery for breast cancer is accomplished by lumpectomy followed by whole-breast irradiation or by mastectomy.

The incidence of breast cancer increases with age, and primary care physicians can expect to see more women ...
What is the most common form of endocrine therapy?
The antiestrogen tamoxifen citrate is the most common form of endocrine therapy in the United States. However, endocrine therapy also includes ovarian ablation in premenopausal women—either surgically, through irradiation to the ovaries, or by the use of a luteinizing hormone-releasing hormone agonist.
How long does adjuvant treatment last?

How long does it take for chemo to cure?
Adjuvant chemotherapy typically begins within three to five weeks of the surgical removal of the cancer and has different treatment lengths depending on the cancer.
Why do cancers develop resistance to chemotherapy?
Goldie and Coleman’s somatic mutation theory of why cancers develop resistance to chemotherapy (published in 1984) postulated tumors become more heterogeneous when they become bigger. They develop different kinds of cells (in proportion to the whole tumor) and some of these cells can resist the chemo agent.
