Pancreatic Cancer: Chemotherapy
What is chemotherapy?
Chemotherapy (chemo) uses anticancer medicines to kill cancer cells. The medicines are made to attack and kill cancer cells, which grow quickly. Some normal cells also grow quickly. Because of this, chemotherapy can also harm those cells. This can cause side effects.
When might chemo be used for pancreatic cancer?
Chemo is part of the treatment for most people with pancreatic cancer. Your healthcare provider may recommend chemo to treat pancreatic cancer in any of the following situations:
If you have pancreatic cancer that has not yet spread to distant parts of your body, but it’s not clear that all of the cancer can be removed. You may get chemo (often with radiation) as the first treatment to try to shrink the tumor and make surgery possible. Treatment before surgery is called neoadjuvant therapy.
If you have surgery to remove the cancer as your first treatment, you may get chemo (often with radiation) to try to make sure all the cancer cells are killed. This is known as adjuvant chemotherapy.
Chemo is often part of treatment if you have cancer that cannot be removed with surgery, or if you are not healthy enough for surgery.
How is chemo given for pancreatic cancer?
Before treatment starts, you’ll meet with a medical oncologist. This is a doctor who specializes in treating cancer with medicines such as chemo. The doctor will discuss your treatment options with you and explain what you might expect.
Depending on the specific chemo medicine you’re taking, you may get them in one of these ways:
Intravenous (IV). The medicine is given through a small needle that has been put into a vein. The medicine may drip in slowly over several hours or even days, or it may be given more quickly over a few minutes. When chemo is given over days, people often go home with a small infusion pump (a bag that looks like a waist pack) that’s disconnected later.
Oral. You swallow these medicines as pills.
Chemo is usually given in an outpatient setting. That means that you get it at a hospital, clinic, or healthcare provider's office, and you can go home after the treatment. Less often, you may need to stay in the hospital during treatment. Your healthcare provider will watch you for reactions during your treatments. Since each of your chemo treatments may last for a while, you may want to take along something that is comforting to you, such as music to listen to. You may also want to bring something to keep you busy, such as a book or mobile device.
To reduce the damage to healthy cells and to give them a chance to recover, chemo is given in cycles. Each cycle consists of one or more days of treatment, followed by some time to rest. Cycles normally last three or four weeks. Most people get four to six cycles as part of their initial treatment, which usually lasts for several months. Your healthcare provider will talk about your schedule with you.
What chemo medicines are used to treat pancreatic cancer?
These are some common chemo medicines used to treat pancreatic cancer:
Albumin-bound paclitaxel (nab-paclitaxel)
Two or more of these medicines are often combined as the first treatment. Sometimes the chemo medicine gemcitabine is combined with the targeted therapy medicine erlotinib. People who are not healthy enough to get two medicines or people who have already gotten chemo may only receive one medicine.
What are common side effects of chemo?
Side effects of chemo are different for everyone. They vary based on the medicines you receive. Below is a list of the some of the most common side effects from chemo. Ask your healthcare provider what side effects to watch for.
If you have hair loss, the hair will often grow back after the treatment stops.
Nausea and vomiting
This side effect can often be controlled with medicines. Ask your healthcare provider about it.
Chemo can sometimes cause mouth sores. This might make it hard for you to eat or swallow. It's important to keep your mouth very clean and avoid foods and substances that could irritate your mouth.
If you have diarrhea, take antidiarrheal medicines as prescribed by your healthcare provider. You may also need to make changes in your diet.
Loss of appetite or changes in the way things taste
Talk to your healthcare provider if you find you’re having trouble eating or are losing weight. There are often ways to help.
Increased risk of infection
During your chemo treatments, your white blood cell count may become low. This means your immune system won’t be working as well as it normally does. It’s a good idea for you to avoid people who have illnesses that you could catch. It’s also a good idea to take extra safety measures against cuts and scrapes that could become infected. Your healthcare provider will check your blood counts regularly during your treatment. Let your healthcare provider know if you have any signs of an infection. Symptoms include fever, sore throat, a new cough, or burning during urination.
Bleeding and bruising more easily
Chemo can also lower your blood platelet counts. Platelets are needed to help the blood clot well.
You may feel tired while getting chemo. This normally goes away once treatment ends.
Some other side effects can also be seen with certain chemo medicines. For example, cisplatin, carboplatin, and some other medicines can cause nerve damage (neuropathy). This can lead to pain, tingling, and numbness in your hands and feet.
Working with your healthcare provider
It's important to know which medicines you're taking. Write your medicines down, and ask your healthcare team how they work and what side effects they might have.
Talk with your healthcare providers about what signs to look for and when to call them. For example, chemo can make you more likely to get infections. Make sure you know what number to call with questions. Is there a different number for evenings and weekends?
It may be helpful to keep a diary of your side effects. A written list will make it easier for you to remember your questions when you go to your appointments. It will also make it easier for you to work with your healthcare team to make a plan to manage your side effects.
Pancreatic Cancer: Treatment Choices
Various types of treatment can be used for pancreatic cancer. Which may work best for you? It depends on a number of factors. These include the size, location, and stage of your cancer. Factors also include your age, overall health, and what side effects you’ll find acceptable.
Learning about your treatment options
You may have questions and concerns about your treatment options. You may also want to know how you’ll feel and function after treatment, and if you’ll have to change your normal activities.
Your healthcare provider is the best person to answer your questions. He or she can tell you what your treatment choices are, how successful they’re expected to be, and what the risks and side effects are. Your healthcare provider may suggest a specific treatment. Or he or she may offer more than one, and ask you to decide which one you’d like to use. It can be hard to make this decision. It is important to take the time you need to make the best decision.
Deciding on the best plan may take some time. Talk with your healthcare provider about how much time you can take to explore your options. You may want to get another opinion before deciding on your treatment plan. In fact, some insurance companies may require a second opinion. In addition, you may want to involve your family and friends in this process.
Understanding the goals of treatment for pancreatic cancer
For some pancreatic cancers, the goal of treatment is to cure the cancer. If cure isn’t possible, treatment may be used to shrink the cancer or keep it under control for as long as possible. Treatment can also improve your quality of life by helping to control the symptoms of the disease. The goals of treatment can include one or more of these things:
Remove or destroy the cancer in your pancreas
Remove or destroy tumors in other parts of your body
Stop or slow the growth or spread of pancreatic cancer cells
Prevent or delay the cancer from coming back
Ease symptoms from the cancer. These can include pain or pressure on your organs.
Types of treatment for pancreatic cancer
Several types of treatment can be used for pancreatic cancer. Different combinations of treatment may be used. These depend on a number of factors, such as:
The size and location of the cancer
The stage (extent) of the cancer
Your age and overall health
Your personal concerns and preferences
Each treatment has its own goals.
This is often the preferred treatment for early stage pancreatic cancer if it can be done. This is because it may cure the cancer if it’s caught early enough. Unfortunately, pancreatic cancer has usually spread too far to be removed completely. If the cancer can’t be removed, your healthcare provider might still suggest a less extensive surgery to ease symptoms.
This treatment is often used with chemotherapy, either before or after surgery. Radiation and chemotherapy (chemo) before surgery can help shrink a tumor and make it easier to take out. After surgery, radiation and chemo can be used to try to kill any cancer cells that are left. Radiation may also be used as part of the main treatment in people who can't have surgery. Or it may be used to help relieve symptoms in people with advanced cancer.
Chemo and targeted therapy
For pancreatic cancer, chemo may be used before or after surgery (often with radiation). Or it may be the main treatment for people who can't have surgery. Targeted therapy medicines work differently from standard chemo medicines. They may be used along with chemo in some situations.
Your healthcare provider may suggest treatments that help ease your symptoms, but don’t treat the cancer. These can sometimes be used along with other treatments. Or your healthcare provider may suggest supportive care if he or she believes that available treatments are more likely to do you more harm than good.
Clinical trials for new treatments
Researchers are always looking for new ways to treat pancreatic cancer. These new methods are tested in clinical trials. Talk with your healthcare provider to find out if there are any clinical trials you should consider.
Talking with your healthcare provider
At first, thinking about treatment options may seem overwhelming. Talk with your healthcare team and loved ones. Make a list of questions. Consider the benefits and possible side effects of each option. Discuss your concerns with your healthcare provider before making a decision.
