Chemotherapy Schedules
How often you will receive chemotherapy will be determined by your doctor, taking into consideration factors such as the stage of your cancer, the types of drugs you receive, the anticipated toxicities of the drugs and the time necessary for your body to recover from these toxicities. The doctor may also consider whether the goal of the chemotherapy is to control the growth of the cancer, or to ease symptoms associated with the disease.
In general, chemotherapy treatment is administered in "cycles" — a "cycle" being defined as a period of treatment followed by a period of rest. This cycle allows the cancer cells to be attacked by the drugs, and then allows the body's normal cells time to recover. The combination of drugs used, the length of time to administer the drugs, how often they should be repeated and the number of cycles recommended have been analyzed throughly in clinical trials. For mesothelioma patients, the "standard" treatment is a combination of Alimta and cisplatin, administered IV, with a 10 minute infusion of Alimta followed by two hours of cisplatin, given in 21 day cycles. Modifications to this schedule may be made according to what your doctor feels is appropriate in your particular case.
The number of treatment cycles, or the length of time between the beginning and end of chemotherapy may vary, however in general, 3 to 4 cycles of treatment are given before response is evaluated; 2 to 3 cycles are considered a minimum to assess for effectiveness. After response to the treatment has been determined, the following criteria will be used to decide whether chemotherapy should continue:
• If there is shrinkage of the tumor, or the disease is kept stable, chemotherapy may be continued for as long as it can be tolerated and there is no disease progression.
• If there is continued disease progression, chemotherapy will be stopped, and the patient will be given alternative options.
The goal of setting a chemotherapy schedule is to make treatment as effective, timely and trouble-free as possible, but while the drugs are working to kill cancer cells, they may also affect healthy cells causing side effects. One of the most common side effects, and one your doctor will monitor carefully, is a chemotherapy-induced low white blood cell count (neutropenia) which means your immune system is weakened, therefore leaving you more prone to infection. While this side effect is anticipated when someone is undergoing chemotherapy, it can cause delays in your treatment schedule, or changes in the dosage of the drugs you will receive.

Note to Patients:
Chemotherapy treatment should be a cooperative effort between you and your doctor. The interaction that takes place is important to your health. It will not only help you feel better, but will also address any potential problems with miscommunication.
1. It is necessary for your doctor to be aware of any side effects which may result from your chemotherapy treatment.
These may include:
o Fever of, or greater than 101 degrees
o Nausea or vomiting
o Diarrhea or constipation
o Fatigue
o Tingling or numbness in the fingers or toes
o Ringing in the ears
o Bruises or rashes
o Sores in the mouth or throat
2. Taking other medication of any kind can alter the effects of chemotherapy or cause undesirable interactions.
Be sure you report all over-the-counter and prescribed medicines to your doctor. Don’t take aspirin unless it has been approved by your doctor. Ask your pharmacist if aspirin is contained in any drugs you plan to purchase.
3. Take extra care with your daily health.
Try to maintain a stable weight by eating a healthy diet and drinking plenty of fluids. If your stomach is upset, ask your doctor for helpful hints or work with a nutritionist who can tailor a program to your needs. Brush your teeth after every meal, or if you can’t brush, rinse your mouth thoroughly with water.
Stay away from people who have colds or the flu. Chemotherapy can compromise your immune system and lower your resistance to germs. Make sure you keep appointments for blood work – these tests help your doctor monitor your health.
4. Be open about your feelings regarding your treatment.
It is normal to feel sad, angry or afraid, however, letting these emotions get out of control can be detrimental to your overall well-being. Seek out the help of family, friends, your doctor, a counselor or a support group
