Hawaii Chemotherapy Treatment

Chemotherapy can be given:

• • Intravenously (IV),
  • By mouth in the form of a pill,
  • With a shot (injection), or
  • By intrathecal and intraventricular injection (meaning into the spinal fluid surrounding the spinal cord or brain).

Many types of chemotherapy can be given at home. Through instruction, you and your family members can learn how to administer chemotherapy in pill form or by injection with small syringes and needles similar to those that people with diabetes use to administer insulin.  In some cases, a nurse will administer chemotherapy in an outpatient clinic. In other cases, it may be necessary to go to the hospital to receive treatment.

Chemotherapy is typically given in cycles, which is a treatment followed by a period of rest. A cycle can last one or more days, but is usually one, two, three, or four weeks long. A course of chemotherapy is comprised of multiple cycles. Each course is different, but generally consists of four to six cycles.

Generally, treatments are given daily, weekly, or monthly. How often you receive chemotherapy depends on the type of cancer and which drug or combination of drugs you receive. If you have been newly diagnosed with cancer, your doctor will help you determine the most effective treatment schedule for you. Chemotherapy is usually given in cycles with rest periods between each administration.

Chemotherapy may be used in combination with surgery.  When chemotherapy is given before surgery it is referred to as neoadjuvant chemotherapy.  The goal of neoadjuvant chemotherapy is to shrink the cancer before it is surgically removed.  If the chemotherapy is given after surgery, it is referred to as adjuvant chemotherapy. The goal of adjuvant chemotherapy is to kill any cancer cells left in the body after surgery. Regardless of whether it is given before or after surgery, chemotherapy will still be administered in cycles that depend on the type of cancer and which drug or combination of drugs.

You will receive chemotherapy that is best suited to achieve your goals of therapy.  When selecting a treatment or treatments, your doctor will consider:

• Your diagnosis
• How far along your cancer is in its development
• The expected behavior of the cancer
• Where the cancer originated
• Your age
• Other medical problems you may have
• Any potential side effects from the treatment.

Chemotherapy is typically given in cycles, which is a treatment followed by a period of rest.  A cycle can last one or more days, but is usually one, two, three or four weeks long. A course of chemotherapy is comprised of multiple cycles. Each course is different, but generally consists of four to six cycles.  The actual administration of the chemotherapy drugs may take minutes to several hours, depending on the drug or drugs given.

If your chemotherapy is given through an IV, your doctor may suggest an implanted venous access device (VAD) or Port-a-Cath.  VADs are surgically placed in a large vein near the heart and can stay in place for long periods of time.  By using a VAD you will not have to have smaller catheters repeatedly placed in arm veins.

Chemotherapy works by destroying cancer cells; unfortunately, it cannot tell the difference between a cancer cell and a healthy cell.  The delivery of cancer therapy often affects the body’s normal tissues or organs that are not affected by cancer. Side effects, or complications of treatment are the undesired consequence of affecting normal cells.

Side effects of treatment may cause inconvenience, discomfort, and occasionally even fatality to patients. The most common side effects of chemotherapy are low blood counts, nausea, vomiting, hair loss, and fatigue.  Some side effects may be temporary and merely annoying.  Others, such as infection or a low white blood count, can be life-threatening.  For example, one of the most serious potential side effects of chemotherapy is a low white blood cell count – a condition called neutropenia (new-truh-pee-nee-ah) – which can put you at risk for severe infections or treatment interruptions.

Many new patients who receive chemotherapy experience fatigue.  Fatigue has many causes but frequently occurs because of anemia caused by the chemotherapy.  Your daily activities should be planned according to how you feel, and you should take rest periods throughout the day as often as you feel necessary. Anemia can be effectively treated.

Without receiving special anti-nausea medications, most patients will experience some nausea after treatment with chemotherapy.  Nausea and vomiting may last 24-48 hours.  The severity of nausea and vomiting mainly depends on which chemotherapy drugs were used.  A number of very effective medications called anti-emetics or anti-nausea drugs are now available to help lessen or prevent nausea and vomiting. These medications may be given to you intravenously during your chemotherapy, or you may be given a prescription medication to take at home.

Your doctor determines what kinds of tests are needed. If you are receiving chemotherapy, you may have blood work done anywhere from the day of or up to 7 days before your scheduled treatment. This blood work will include a complete blood count (CBC), chemistry profile, and any necessary cancer markers. A blood sample for a complete blood count (CBC) will also be collected seven to fourteen days following your chemotherapy. It is important to be aware of possible symptoms of reduced red blood cell (RBC), white blood cell (WBC), or platelet (PLT) production. Be sure to report any of the following:

• Fever (over 101º F), congestion, or a cold.
• A rash, blister, easily bruised skin, signs of bleeding, an infected cut, itching or burning in the genital area.
• Weakness, fatigue, or shortness of breath.

Chemotherapy destroys rapidly dividing cells, a characteristic of cancer cells. However, red blood cells, white blood cells, and platelets also divide rapidly and are frequently damaged by chemotherapy. Your red blood cell count, white blood cell count, and platelet count may all go down. Your doctor monitors these counts to determine the toxicity of treatment and to predict your risk for complications, as well as to plan future therapy.  For more information, see section on Understanding and Monitoring Your Blood Counts.

Hair loss occurs with some, but not all, chemotherapy drugs. The amount of hair loss varies from a slight thinning to complete baldness and affects the scalp, eyelashes and eyebrows, legs, armpits, and pubic area.

Hair loss will typically begin two or three weeks after your first treatment. The amount of hair that you lose will depend on the type of chemotherapy drug you are taking. Hair typically begins to grow back approximately 2-3 weeks after treatment is finished. The hair may grow back differently than it was before treatment. For example color or texture (curly or straight) may be different. Remember that hair loss associated with chemotherapy is temporary and the hair will grow back.
