Treatment Name: Paclitaxel (Taxol®)
How does Paclitaxel work?
It is designed to prevent cancer cells from dividing into more cancer cells, which often kills the cancer cell in the process.
Goals of therapy:
Paclitaxel is commonly given to kill any remaining cancer cells after surgery is performed. This reduces the risk of the cancer coming back in the same breast, or the other breast. Paclitaxel is commonly given with the goal of cure.
- Paclitaxel intravenous (I.V.) given over three hours on Day 1 of every 21-day cycle (four doses total)
- Paclitaxel I.V. given over one hour, once per week for 12 straight weeks
- Patients with hormone-receptor positive breast cancer cells may benefit from further treatment with oral anti-estrogen tablets such as tamoxifen, letrozole, or anastrozole to reduce the risk of the cancer coming back

Estimated total infusion time for this treatment:
- Up to four hours for the infusion given on the every 3-week schedule
- Up to two hours for the infusion given every week
- Infusion times are based on clinical studies, but may vary depending on doctor preference or patient tolerability. Pre-medications and intravenous (I.V.) fluids, such as hydration, may add more time
Paclitaxel is usually given in an outpatient infusion center, allowing the person to go home afterwards. Once all treatment with paclitaxel is complete, then oral anti-estrogen medications may be taken at home.
Duration of therapy may last up to four months, depending upon response, tolerability, and number of cycles prescribed.
In clinical studies, the most commonly reported paclitaxel side effects are shown here:
*Although hair loss was not reported in this dose-response study, it can occur in up to 50% of patients. See DailyMed package insert.
How often is monitoring needed?
Labs (blood tests) will likely be checked before every new cycle of chemotherapy treatment. Labs often include: Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), plus any others your doctor may order.
How often is imaging needed?
Imaging such as a chest x-ray, computerized tomography (CT) scan, or magnetic resonance imaging (MRI) scan may be checked before treatment, or after treatment if your doctor recommends based upon your specific situation.
How might blood test results/imaging affect treatment?
Depending upon the results, your doctor may advise to continue paclitaxel as planned, or delay or switch therapy. For example, if the CBC blood test shows that the neutrophil (infection-fighting white blood cells) count is below normal, your doctor may delay treatment.
- Paclitaxel may cause a reaction during the infusion known as hypersensitivity. The reaction is most often prevented using several medications, such as diphenhydramine (Benadryl®), either ranitidine or famotidine, and a steroid such as dexamethasone
- A pharmacist should ALWAYS review your medication list to ensure that drug interactions are prevented or managed appropriately
- Clinical trials may exist for early stage breast cancer. Ask your doctor if any studies are currently enrolling in your area. If not, go to clinicaltrials.gov to search for other centers offering study medications.

What is Emotional Wellness?
Emotional wellness is having a positive outlook balanced with a realistic understanding of current life events. This requires both an awareness and acceptance of your emotions. It is with this knowledge that you can develop a plan to take the necessary actions to positively impact your life.
Emotional wellness uses an ongoing process to continually reflect on the stressors of life in a constructive manner to move forward and create happiness.
Because emotional wellness is deeply connected with physical, social, and spiritual wellness, pursuing it often becomes particularly difficult in times of major illness. Despite this difficulty, working toward emotional wellness has been connected to improved treatment outcomes and a higher likelihood of achieving goals of therapy.

What is Breast Cancer - early stage?
What is Early Stage Breast Cancer?
A disease of either the milk-producing glands known as lobules, or milk ducts, or other cells found in the breast. Early stage breast cancer may also affect the lymph nodes, but has not usually spread to other areas of the body. Breast cancer is the most common type of cancer diagnosed in women, but may rarely affect men as well. Breast cancer cells may have increased expression of estrogen receptors (ER positive or negative), progestin receptors (PR positive or negative), and/or HER-2 receptors (HER-2 positive or negative). The presence or lack of these receptors will help determine the most effective chemotherapy medications to give.
Genetic causes, such as the BRCA (pronounced "Bracka") mutation, significantly increase the risk of developing breast cancer. Other risk factors for breast cancer include family history of breast cancer, high fat diet, and obesity. The stage of breast cancer can vary at diagnosis and throughout treatment. Stages of breast cancer include I, II, III, and IV. The effectiveness of the treatment may depend upon the stage at diagnosis.
Types of breast cancer:
1. Hormone-receptor positive or negative (60 - 65% of patients)
- Estrogen Receptor positive (ER)+ or negative (ER)-
- Progestin Receptor positive (PR)+ or negative (PR)-
2. Hormone Epidermal growth factor Receptor-2 (HER-2) positive or negative (20 - 25% of patients)
- HER-2 + (positive)
- HER-2 - (negative)
3. Triple Negative (15 - 18% of patients)

What is a CBC?
A Complete Blood Count (CBC) is a frequently ordered blood test that tells clinicians the status of your: 1) White blood cell count, 2) Hemoglobin, and 3) Platelet count at the time the test was taken.
1) White blood cell count (WBC): is used to determine infection risk, or response to chemotherapy. Certain chemotherapy agents may harm our good infection-fighting cells. Sometimes chemotherapy may need to be delayed to allow these cells to recover.
2) Hemoglobin: is used to determine if someone is anemic. Anytime the hemoglobin is below 12 g/dL, the person is said to be anemic. Red blood cell transfusions, and sometimes iron can be given to restore the hemoglobin level, but anemia treatment should always aim at treating the underlying cause or condition.
3) Platelet count: is used to determine if the risk of bleeding is increased or if a platelet transfusion is required to prevent bleeding. Certain medications that increase bleeding risk, such as: aspirin, certain chemotherapy agents, and blood thinners, may need to be stopped temporarily until the platelet count is within a safe range.
What is a CMP?
A Comprehensive Metabolic Panel (CMP) is a frequently ordered blood test that tells clinicians the status of your: 1) Electrolytes & Acid/Base status, 2) Kidney function, 3) Liver function, 4) Blood sugar, and 5) Calcium at the time the test was taken. It is commonly used to monitor liver and kidney function when beginning new medications such as chemotherapy. A total of 14 tests are run simultaneously and are shown below.
Electrolytes & Acid/Base status:
1) Sodium, 2) Potassium, 3) Carbon dioxide, 4) Chloride
5) BUN (blood urea nitrogen), 6) Serum creatinine (Scr)
7) AST, 8) ALT, 9) Total bilirubin, 10) Alk Phos, 11) Albumin, 12) Total protein
13) Serum glucose
14) Serum calcium
