Procarbazine is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. Procarbazine
is classified as an "alkylating agent." (For more detail, see "How Procarbazine
Works" section below).
What Procarbazine Is Used For:
- Treatment of Hodgkin's disease.
- Other uses include non-Hodgkin's lymphoma, brain tumors, melanoma, lung cancer,
and multiple myeloma.
Note: If a drug has been approved for one use, physicians sometimes elect
to use this same drug for other problems if they believe it might be helpful.
How Procarbazine Is Given:
- Procarbazine is taken in capsule form by mouth. It comes in 50 mg capsule
- The amount of Procarbazine you will receive depends on many factors, including your
height and weight, your general health or other health problems, and the type of
cancer you have. Your doctor will determine your exact dosage and schedule.
Side Effects of Procarbazine:
Important things to remember about the side effects of Procarbazine:
- Most people do not experience all of the side effects listed.
- Side effects are often predictable in terms of their onset and duration.
- Side effects are almost always reversible and will go away after treatment is complete.
- There are many options to help minimize or prevent side effects.
- There is no relationship between the presence or severity of side effects and the
effectiveness of the medication.
The following side effects are common (occurring in greater than 30%) for patients
Nadir: Meaning low point, nadir is the point in time between chemotherapy
cycles in which you experience low blood counts.
Onset: none noted
Nadir: 3 to 6 weeks after therapy.
Recovery: platelets 4-6 weeks
The following are less common side effects (occurring in 10 -29%) for
patients receiving Procarbazine:
- Hair loss.

be affected by Procarbazine. Discuss this issue with your health care provider.
Delayed Effects of Procarbazine:
- There is a slight risk of developing a blood cancer such as leukemia years after
taking Procarbazine. Talk to your doctor about this risk.
Not all side effects are listed above. Some that are rare (occurring in less than
10% of patients) are not listed here. However, you should always inform your

Monitoring and Testing While Taking Procarbazine:
You will be checked regularly by your health care professional while you are taking
Procarbazine, to monitor side effects and check your response to therapy.
Periodic blood work to monitor your complete blood count (CBC) as well as the function
of other organs (such as your kidneys and liver) will also be ordered by your doctor.
How Procarbazine Works:
Cancerous tumors are characterized by cell division, which is no longer controlled
as it is in normal tissue. "Normal" cells stop dividing when they come
into contact with like cells, a mechanism known as contact inhibition. Cancerous
cells lose this ability. Cancer cells no longer have the normal checks and
balances in place that control and limit cell division. The process of cell
division, whether normal or cancerous cells, is through the cell cycle. The
cell cycle goes from the resting phase, through active growing phases, and then
to mitosis (division).
The ability of chemotherapy to kill cancer cells depends on its ability to halt
cell division. Usually, the drugs work by damaging the RNA or DNA that tells
the cell how to copy itself in division. If the cells are unable to divide,
they die. The faster the cells are dividing, the more likely it is that chemotherapy
will kill the cells, causing the tumor to shrink. They also induce cell suicide
(self-death or apoptosis).
Chemotherapy drugs that affect cells only when they are dividing are called cell-cycle
specific. Chemotherapy drugs that affect cells when they are at rest are called
cell-cycle non-specific. The scheduling of chemotherapy is set based on the
type of cells, rate at which they divide, and the time at which a given drug is
likely to be effective. This is why chemotherapy is typically given in cycles.
Chemotherapy is most effective at killing cells that are rapidly dividing.
Unfortunately, chemotherapy does not know the difference between the cancerous cells
and the normal cells. The "normal" cells will grow back and be healthy but in the
meantime, side effects occur. The "normal" cells most commonly affected by
chemotherapy are the blood cells, the cells in the mouth, stomach and bowel, and
the hair follicles; resulting in low blood counts, mouth sores, nausea, diarrhea,
and/or hair loss. Different drugs may affect different parts of the body.
Chemotherapy (anti-neoplastic drugs) is divided into five classes based on how they
work to kill cancer. Although these drugs are divided into groups, there is
some overlap among some of the specific drugs. The following are the types
Procarbazine is classified as an alkylating agent. Alkylating agents are most
active in the resting phase of the cell. These drugs are cell-cycle non-specific.
There are several types of alkylating agents.
- Mustard gas derivatives: Mechlorethamine, Cyclophosphamide, Chlorambucil,
Melphalan, and Ifosfamide.
- Ethylenimines: Thiotepa and Hexamethylmelamine.
- Alkylsulfonates: Busulfan.
- Hydrazines and Triazines: Altretamine, Procarbazine, Dacarbazine and Temozolomide.
- Nitrosureas: Carmustine, Lomustine and Streptozocin. Nitrosureas are
unique because, unlike most chemotherapy, they can cross the blood-brain barrier.
They can be useful in treating brain tumors.
- Metal salts: Carboplatin, Cisplatin, and Oxaliplatin.
