What are the side effects of immunotherapy for Lymphoma

Side Effects of Immunotherapy for Lymphoma

Immunotherapy has become an important treatment option for lymphoma, but like all cancer treatments, it can cause side effects. Let me explain what you might experience and what's important to know.

Common Side Effects

Flu-like symptoms are among the most frequent side effects:

• Fever, chills, and body aches
• Fatigue (feeling very tired)
• Headaches
• These often occur within hours to days after treatment and typically improve within a few days

Infusion-related reactions can happen during or shortly after the immunotherapy is given:

• Chills and fever
• Shortness of breath
• Chest pain or pressure
• Rapid heartbeat
• Your care team monitors you closely during infusions and can slow or stop the infusion if needed

Skin reactions are common:

• Rash or itching
• Redness at the injection site
• Usually mild to moderate

More Serious Side Effects (Less Common)

Immune-related side effects occur because immunotherapy activates your immune system. In some cases, your immune system can become overactive and attack healthy cells:

• Inflammation of organs - Your lungs, heart, liver, or kidneys can become inflamed
• Autoimmune reactions - Your immune system may attack your own tissues
• Severe infections - Because immunotherapy affects immune function, serious infections can develop
• Low blood cell counts - Affecting your ability to fight infection or clot blood

Important Monitoring

According to NCCN Guidelines for Lymphoma, your care team will:

• Monitor you closely during and after each treatment
• Check your blood counts regularly
• Watch for signs of infection or organ inflammation
• Adjust your treatment if serious side effects develop

Managing Side Effects

Many side effects can be managed with:

• Medications to reduce fever or pain
• Anti-nausea medications if needed
• Rest and hydration
• Skin care products for rashes
• Close communication with your care team about any new symptoms

Key Questions to Ask Your Oncologist

1. Which specific immunotherapy am I receiving, and what side effects are most common with this drug?
2. What symptoms should I report immediately versus those I can monitor at home?
3. How will you monitor me for serious immune-related side effects?
4. What medications or supportive care can help manage side effects?
5. If I develop serious side effects, how will that affect my treatment schedule?

Important Note About CAR T-Cell Therapy

If your treatment includes CAR T-cell therapy (a specialized immunotherapy), there are specific side effects to know about:

• Cytokine release syndrome (CRS) - A reaction from the immune system being activated, causing fever, chills, and sometimes more serious symptoms
• Neurotoxicity - Confusion, difficulty speaking, or seizures (rare but important to monitor)

According to recent FDA-approved CAR T-cell therapies for lymphoma, these side effects require specialized monitoring in a hospital setting, and your care team will have protocols to manage them.

The Balance

It's important to remember that while immunotherapy can cause side effects, it has also shown remarkable effectiveness for many lymphoma patients. The NCCN Guidelines emphasize that the benefits often outweigh the risks, especially for patients with relapsed or refractory disease (lymphoma that has returned or didn't respond to prior treatment).
