When you or a loved one is diagnosed with cancer, it's normal to feel a little scared and nervous when your doctor talks about a treatment like R-CHOP. There are many questions that come to mind, such as what these words mean, what this treatment is like, and what will happen as a result. That's why, as if your friend were telling you about it in simple terms, we'll talk about everything about R-CHOP treatment today.
Simply put, what is R-CHOP?
R-CHOP is a cancer treatment. To be precise, it is a combination of five drugs. It is specifically used to treat a type of cancer called Non-Hodgkin Lymphoma . This combination of drugs includes three chemotherapy drugs, a targeted therapy drug, and a corticosteroid.
Each letter in this name represents a type of medicine. It's very simple, see.
| Letter | Name of the drug | What happens with this? |
|---|---|---|
| R | Rituximab | This is a targeted therapy. This means that the drug attaches to a specific protein on cancer cells. Our body's immune system can then easily find and destroy these cancer cells. |
| C | Cyclophosphamide | This is a chemotherapy drug. These drugs work by destroying rapidly dividing cells (like cancer cells). |
| H | Doxorubicin Hydrochloride | This is also a chemotherapy drug. |
| O | Vincristine Sulfate | This is another chemotherapy drug. |
| P | Prednisone | This is a type of steroid (corticosteroid). It helps kill cancer cells and also helps reduce allergic reactions that can occur with other medications. |
Because most of these drugs are chemotherapy drugs, some people also call this treatment "R-CHOP chemo." But because the drug Rituximab helps our immune system, your doctor may also call it "immuno-chemotherapy."
What types of diseases is R-CHOP treatment used for?
Doctors mainly use R-CHOP to treat a type of cancer called non-Hodgkin lymphoma . It is also a very effective treatment for one of the most common types of lymphoma, diffuse large B-cell lymphoma (DLBCL) .
In addition, R-CHOP is also used in the following situations:
- Advanced follicular lymphoma
- Mantle cell lymphoma
- Waldenstrom macroglobulinemia
How does the treatment happen? (Treatment Cycle)
You will receive R-CHOP treatment in cycles. Each cycle usually lasts three weeks (21 days). This cycle is divided into two parts:
1. Treatment days: The days you are given medication.
2. Rest days: Days to allow your body to recover, that is, to recover, before the next round.
How are the treatment days going?
You will need to take medicine for five days. The steroid called Prednisone (P) is taken as a pill. The other four medicines (R, C, H, O) are given to you by intravenous infusion (IV). This means they are given into a vein like saline. You will need to go to a hospital or clinic for this.
During this treatment, you will be seated in a chair. A machine will give you the medicine through a plastic tube into a vein in your arm, hand, or chest. Sometimes, to make it easier to continue receiving treatment, a small device called a chemo port is implanted under the skin of your chest.It is also called one.
The first round of treatment usually goes like this:
- Before the treatment begins, you will be given medication to stop vomiting and nausea .
- Also, medications are given to prevent allergies . It is common to have a minor reaction (e.g., feeling hot, dizzy) when you are given the drug Rituximab (R). However, the previous medication largely prevents severe reactions.
The importance of rest days
In a typical cycle of R-CHOP, you get 16 days of rest after five days of treatment. This time is very important. Because when R-CHOP destroys cancer cells, it is also very tiring for the body. So it is normal to feel very tired after treatment. During these rest days, it is a good idea to ask a family member or friend to help you with your daily tasks.
During your recovery, if you are physically able, your doctor may recommend that you do small activities, such as walking, drinking plenty of water, and eating nutritious foods.
How long should this treatment be done?
Most people receive six cycles of R-CHOP. Each cycle is three weeks long, so the total treatment time is about 18 weeks. However, the number of cycles you need depends on your condition. Some people may need eight cycles. Some doctors may recommend two-week cycles instead of three-week cycles.
Your doctor is the best person to make this decision . He or she will clearly explain the treatment plan you need.
What are the benefits of R-CHOP treatment?
The biggest advantage of this is that it's not a single drug, but a combination of five drugs. Each of these drugs kills cancer cells in different ways. So, instead of one soldier fighting, it's like an entire army coming together to fight cancer.
The success rate of R-CHOP treatment is very high . For example, up to 70% of people with a type of cancer called DLBCL achieve complete remission. This means that all symptoms disappear. If the disease does not recur for five years, the cancer is usually considered to be free of recurrence.
Of course, this treatment cannot guarantee that it will completely eliminate the cancer or stop it from coming back in everyone. However, R-CHOP is considered one of the safest and most effective treatments available for non-Hodgkin lymphoma.
Side Effects and Risks
Like any treatment, R-CHOP has side effects. But don't worry. Your doctor will give you medication to prevent these major side effects (like vomiting) and to control things like low white blood cells. It's important to talk openly about these risks with your doctor before starting treatment.
Infusion reactions
Many people may have a mild reaction to Rituximab during their first round of treatment. This is why doctors give the drug very sparingly at first. It's common to feel dizzy or hot, and it will go away after a while. However, if you have symptoms of a severe reaction, you should seek medical attention right away . These symptoms include:
- Skin rash
- Itching
- Swelling of the mouth or lips
- Feeling like your throat is constricted
The medical staff will monitor you while you are being given the medication. However, if you experience any of these symptoms after you go home, go to the hospital's Emergency Department (ETU) immediately.
Common side effects
All of the drugs in R-CHOP can cause side effects. But not everyone gets them. It varies from person to person. Let's look at the most common side effects and how to deal with them.
| Side effect | Simple explanation and management |
|---|---|
| Red/pink urine | Doxorubicin (H) is a red drug. So your urine may turn red/pink for about 48 hours after treatment. This is normal, don't worry. |
| Nausea and vomiting | Even if you are given medicine to prevent vomiting, sometimes you may feel nauseous. Take the medicine exactly as prescribed by your doctor. Also, avoid eating large meals and eating oily/spicy foods. |
| Hair loss | This is a common side effect of chemotherapy. Hair loss can begin about three weeks after the first dose of medication. ButHair will grow back after treatment is over. |
| Having a cold and getting a fever | Chemotherapy reduces the number of white blood cells. This increases the risk of infection. You will be given a shot called G-CSF, which helps produce white blood cells. However, if you develop a fever, tell your doctor immediately. |
| Hard work and effort | R-CHOP treatment can cause a decrease in red blood cells (anemia). This can make you feel very tired. Ask for help with daily tasks. Light exercise, such as walking for about 30 minutes a day, is good, but rest if you feel tired. |
| Easy bleeding and bruising | As the number of platelets decreases, even a small injury can cause bleeding and bruising. Be careful not to injure yourself. Tell your doctor if you have these symptoms. |
| Numbness in the limbs | You may experience numbness or tingling in your hands and feet. This is called peripheral neuropathy. If you experience these symptoms, tell your doctor. |
In addition, other side effects may occur:
- Mouth sores
- Headache
- Constipation or diarrhea
- Heartburn
- Muscle weakness
- Insomnia
- Mood changes
- Heart palpitations
Possible long-term effects after treatment
Most side effects go away over time after treatment ends.
However, depending on factors such as the strength of the medication you receive, R-CHOP treatment may slightly increase your risk of developing heart disease or other types of cancer in the future. It may also affect fertility . This means that if you are planning to have children in the future, talk to your doctor about this beforehand. You may be able to discuss options such as freezing your eggs or sperm.
What is the difference between R-CHOP and CHOP?
Simply put, R-CHOP is an improved version of the CHOP treatment. CHOP was introduced in the 1990s and was the best treatment for non-Hodgkin lymphoma at the time.
But in the early 2000s, researchers added the targeted therapy drug Rituximab (R) to the CHOP regimen. This addition increased the cure rate even further. Today, R-CHOP is the most effective treatment, replacing CHOP.
