Neoadjuvant chemotherapy is a treatment option for breast cancer where chemotherapy is given before surgery. The goal of this approach is to shrink the tumor, making it easier to remove surgically and potentially increasing the chances of a successful outcome. This approach is most commonly used for larger tumors or when the cancer has spread to nearby lymph nodes. It also allows doctors to see how the tumor responds to chemotherapy, which can guide further treatment decisions.
When is neoadjuvant chemotherapy used to treat breast cancer?
Neoadjuvant chemotherapy is typically used when breast cancer is at an early stage, but the tumor is large or has spread to nearby lymph nodes. It can also be used when breast cancer is at a more advanced stage and the tumor is not considered to be operable or if the patient has a medical condition that makes surgery high-risk. Additionally, if the patient is not a surgical candidate, neoadjuvant chemotherapy can be used as a primary treatment to shrink the tumor and improve chances for breast preservation. The treatment plan and the decision of using neoadjuvant chemotherapy is based on the stage and the grade of the cancer, the patient’s overall health and the preference of the patient and the oncologist.
The benefits of neoadjuvant chemotherapy
There are several potential benefits to using neoadjuvant chemotherapy for breast cancer, including:
1. Tumor shrinkage
Neoadjuvant chemotherapy can shrink the tumor before surgery, making it easier to remove and potentially increasing the chances of successful surgical outcomes.
2. Improved surgical options
In some cases, neoadjuvant chemotherapy can make breast-conserving surgery (lumpectomy) an option for patients who would otherwise need a mastectomy.
3. Better assessment of response
The response of the tumor to neoadjuvant chemotherapy can be used to predict the patient’s prognosis and inform further treatment decisions.
4. Potential for breast preservation
Neoadjuvant chemotherapy may allow the patient to preserve their breast, if the tumor has shrunk enough.
5. Lower chance of recurrence
Some studies have shown that neoadjuvant chemotherapy may lower the chance of recurrence and improve overall survival.
6. Better quality of life
Neoadjuvant chemotherapy may allow patients to avoid some of the more extensive surgery and radiation, which can improve the overall quality of life.
The potential side effects of neoadjuvant chemotherapy
Neoadjuvant chemotherapy, like other forms of chemotherapy, can cause a variety of side effects. Some common side effects of neoadjuvant chemotherapy for breast cancer include:
Many patients experience fatigue and a general feeling of weakness during chemotherapy.
2. Nausea and vomiting
These symptoms may occur as a result of the drugs used in chemotherapy.
3. Hair loss
Chemotherapy drugs can cause hair loss, although this is usually temporary.
4. Risk of infection
Chemotherapy drugs can weaken the immune system, making it more difficult for the body to fight off infections.
Chemotherapy can cause anemia by reducing the number of red blood cells in the body.
Chemotherapy can also reduce the number of white blood cells in the body, making patients more susceptible to infections.
7. Diarrhea or Constipation
Chemotherapy can cause changes in bowel function.
Chemotherapy drugs can cause nerve damage, which can result in tingling, numbness, or pain in the hands and feet.
9. Cardiac toxicity
Certain chemotherapy drugs can cause heart problems, including heart damage.
10. Menopausal symptoms
Some chemotherapy drugs can cause menopausal symptoms such as hot flashes, vaginal dryness and night sweats.
Does neoadjuvant chemotherapy improve the outlook of people with breast cancer?
The use of neoadjuvant chemotherapy can improve the outlook for some people with breast cancer, but it depends on the stage and characteristics of cancer. In general, neoadjuvant chemotherapy has been shown to be beneficial for people with larger tumors or those who have cancer that has spread to nearby lymph nodes. Studies have shown that the use of neoadjuvant chemotherapy can lead to a higher rate of breast conservation, and can also lead to a lower rate of recurrence and improved overall survival.
However, the decision to use neoadjuvant chemotherapy should be based on the specific characteristics of the cancer, and the patient’s overall health and preferences. In some cases, neoadjuvant chemotherapy may not be recommended or may not be appropriate. The oncologist will discuss the benefits and risks of neoadjuvant chemotherapy with the patient and will help to determine if it is the best option for the individual case.

It is typically used when breast cancer is at an early stage, but the tumor is large or has spread to nearby lymph nodes or when the patient is not a surgical candidate. The benefits of neoadjuvant chemotherapy include tumor shrinkage, improved surgical options, better assessment of response, potential for breast preservation, lower chance of recurrence, and better quality of life. But it also comes with side effects such as fatigue, nausea, vomiting, hair loss, risk of infection, anemia, neutropenia, diarrhea, constipation, neuropathy, cardiac toxicity and menopausal symptoms. The decision to use neoadjuvant chemotherapy is tailored to each individual case, taking into consideration the stage and characteristics of the cancer, the patient’s overall health and preferences.
