Chemotherapy (cont.)
What Can Chemotherapy Do?
Depending on the type of cancer and how advanced it is, chemotherapy can be
used for different goals:
- To cure the cancer. Cancer is considered cured when the patient
remains free of evidence of cancer cells.
- To control the cancer. This is done by keeping the cancer from
spreading; slowing the cancer's growth; and killing cancer cells that may
have spread to other parts of the body from the original tumor.
- To relieve symptoms that the cancer may cause. Relieving symptoms
such as pain can help patients live more comfortably.
Is Chemotherapy Used With Other Treatments?
Sometimes chemotherapy is the only treatment a patient receives. More often,
however, chemotherapy is used in addition to surgery, radiation therapy, and/or
biological therapy to:
- Shrink a tumor before surgery or radiation therapy. This is called
neo-adjuvant therapy.
- Help destroy any cancer cells that may remain after surgery and/or
radiation therapy. This is called adjuvant chemotherapy.
- Make radiation therapy and biological therapy work better.
- Help destroy cancer if it recurs or has spread to other parts of the
body from the original tumor.
Which Drugs Are Given?
Some chemotherapy drugs are used for many different types of cancer, while
others might be used for just one or two types of cancer. Your doctor recommends
a treatment plan based on:
- What kind of cancer you have.
- What part of the body the cancer is found.
- The effect of cancer on your normal body functions.
- Your general health.
What About Clinical Trials?
Clinical trials, also called cancer treatment studies or research studies,
test new treatments in people with cancer. Clinical trials test many types of
treatments such as new drugs, new approaches to surgery or radiation therapy,
new combinations of treatments, or new methods such as gene therapy. The goal of
this research is to find better ways to treat cancer and help cancer patients.
There are different types of clinical trials, called Phase I, Phase II, and
Phase III trials. Each is one of the final stages of a long and careful cancer
research process. If your doctor does not suggest you take part in a clinical
trial, you may want to ask about clinical trials as a treatment choice for you.
Possible benefits of clinical trials include:
- Clinical trials offer high-quality cancer care.
- If a new treatment approach is proven to work and you are taking it, you
may be among the first to benefit.
- By looking at the pros and cons of clinical trials and other treatment
choices, you are taking an active role in a decision that affects your life.
- You have the chance to help others and improve cancer treatment.
Possible drawbacks:
- New treatments under study are not always better than, or even as good
as, standard treatment.
- Even if a new treatment has benefits, it may not work for you.
- In a study, if you are randomly assigned to have standard treatment
instead of the new treatment being tested, it may not be as effective as the
new approach.
- Health insurance and managed care providers do not always cover all
patient care costs in a study.
Before deciding to join a clinical trial you will want to ask important
questions such as: What are the possible short- and long-term risks, side
effects, and benefits to me? How could the study affect my daily life? Will I
have to pay for any treatment, tests, or other charges?
The National Cancer Institute's (NCI) booklet
Taking Part in Clinical Trials: What Cancer Patients Need to Know lists
questions you may want to ask your doctor and helps answers many of the
questions you may have about clinical trials. It also informs you about your
rights and protections. For example, you are free to leave a study at any time.
You may order the booklet by calling NCI's Cancer Information Service at
