Does Immunotherapy Have Serious Side Effects
Immunotherapy with PD1/PD-L1 inhibitors is generally well tolerated, but serious side effects may occur. This happens in about 20% of people given PD1/PD-L1-inhibitors. It occurs in 40% to 60% of people given a combination of PD1-inhibitor and CTLA4-inhibitor immunotherapies.
Most side effects appear around two to three months after therapy starts. However, close monitoring, early recognition, and prompt therapy can help control side effects. Because immunotherapy drugs unleash immune cells, inflammation may occur in organs such as the colon , lungs , skin , liver , thyroid gland , and other areas of the body.
How Chemotherapy Affects Your Immune System Depends On A Number Of Factors
Its important to note that how exactly chemotherapy affects your immune system can depend on a variety of factors, such as:
- the type of chemotherapy drug thats used
- the dose of chemotherapy thats used
- what type and stage of cancer you have
- your age and overall health
Many different types of vaccines are in use today. Some are safe for people whove had chemotherapy, while others are not. Lets explore each one in a little more detail now.
Cancer Treatments And Blood Counts
While destroying or damaging cancer cells, treatments may also damage healthy blood cells and the bone marrow the body uses to produce new immune cells. And when treatments like chemotherapy and radiation therapy are used together, the combination may lead to conditions that lower blood counts and increase the risk of infection, including:

Precuations To Be Taken By Patients To Cope Up With A Weak Immune System
During and even after cancer treatment, patients body might temporarily be unable to fight bacteria, viruses, fungi, and other germs. Hence, it is really important to take certain steps to protect oneself against infection when a patients immune system is weakened by the cancer treatments. In addition, these steps become absolutely critical if it is confirmed that the white blood cells count is low.
Below are some of the precautionary measures most often recommended for patients whose immune system is weakened by the ongoing cancer treatments. These measures cannot eliminate the infection completely but can help lower the risk of infection.
1. Sound Sleep
A 7 hours of sleep a night is really important for the patients after chemotherapy. It is not bad to get less sometimes, but getting not enough sleep most nights, it could strain the immune system. And as a result, patient is more likely to get sick from colds, flu, and more serious infections. Also, the recovery is slower as compared with a healthy person.
2. Balanced and healthy diet
For many patients with cancer, exercise is key for a healthy immune system. We advise to consult your treating doctor on the same. One should keep in mind when to skip exercises program, for example
- In case of extreme fatigue
- In case of anaemia /Low haemoglobin
- In case of poor muscle coordination
- In case of low white blood cells count
4. Stress management
5. Personal hygiene
6. Avoiding cuts or skin breaks
7. Avoiding germs
Will I Get Late Effects After My Treatment
Late effects are health conditions that can develop months or even years after treatment for lymphoma. Modern treatments are designed to treat lymphoma effectively while keeping the risk to your long-term health as low as possible. Your doctor will monitor you for late effects at your follow-up appointments.
Late effects from lymphoma treatment dont affect everyone. Attending your follow-up appointments means your medical team can closely monitor your health for late effects once treatment has ended.

Does Immunotherapy Benefit All Patients
Immunotherapy benefits some, but not all, cancer patients. It seems to work better for certain cancers for example, cancers with higher levels of PD-L1 protein or a massive number of gene mutations due to DNA repair defects. However, there are many exceptions, and we do not fully understand how best to select patients who will benefit.
Is It Safe For A Cancer Survivor To Receive A Covid
Yes, the , including the booster, is safe for cancer survivors. The National Comprehensive Cancer Network recommends that people with a history of cancer be vaccinated against COVID-19 as soon as possible.
The FDA also approved as a prophylactic for adults who are immunocompromised and who may not be able to mount an immune response to the COVID-19 vaccination.

Chemo Brain And Stress
Many people experience mental changes after chemotherapy treatment. This is sometimes called chemo brain. You may have problems such as poor memory, trouble finding words, difficulty focusing. This can affect parts of your life, including caring for your family and managing your job.
Some things that help with chemo brain include keeping a calendar, writing everything down, and exercising your brain with puzzles and reading. Try to focus on 1 task at a time instead of more than 1 task. You can also work with an occupational therapist for cognitive behavioral rehabilitation. This is a treatment to help you if you have cognitive issues. Occupational therapists work in the Department of Rehabilitation Medicine, Occupational and Physical Therapy. For more information about cognitive behavioral rehabilitation, talk with your healthcare provider for a referral.
Try to avoid having goals for yourself that are too high. This can add to your stress level and frustration. Most people say it takes 6 to 12 months after they finish chemotherapy before they truly feel like themselves again. Read the resource Managing Cognitive Changes for more information about managing chemo brain.
Keeping Well After Treatment
Its important to take guidance from your medical team. However, the general advice is to follow a healthy lifestyle. This includes eating well, doing exercise thats suitable for you, keeping a healthy weight, limiting your alcohol intake and not smoking. You can find more information about these and other healthy lifestyle factors on the NHS website.

Rules For Safe Cooking At Home
- ALWAYS your wash hands before preparing food.
- Never cool or defrost foods at room temperature, such as on the counter top.
- Cook foods until they reach the right temperature. Cook all beef, poultry and pork until it is well done, no pink juices. Cook eggs so that both the white and yolk are firm, nothing runny should be eaten. Reheat all foods until they are steaming hot.
- Hold foods at the right temperature. Do not let meats or gravies sit out at room temperature. If hot foods are going to be eaten later, either keep the food hot on the stove or cool them quickly in the refrigerator. If cold foods are going to be eaten later, keep them in the refrigerator or freezer.
- Wash all fruits and vegetables well before eating or cooking them.
- Only drink milk that is pasteurized, never drink “raw” or “fresh” milk.
- Always allow the patient to take the first helping of a family style dish such as a casserole.
- Do not allow the patient to eat left-overs that others have eaten from. Any leftover must be used within 24 hours.
- Get rid of all foods with expired dates.
- Purchase an antibacterial soap for hand and dish washing. Keep all food preparation surfaces clean with an anti-bacterial cleaning product.
How Are Side Effects Of Immunotherapy Managed
Severe side effects are controlled by stopping the immunotherapy and starting corticosteroids , which are tapered slowly over a period of weeks. If youve had immunotherapy at any time in the past, report any new symptom to your treating oncologist before self-medicating with drugs purchased over the counter. For example, if you have diarrhea, taking loperamide may arrest the symptom. But it won’t address the root cause, which is inflammation of the large intestine. Uncontrolled inflammation of the intestine may lead to rupture of the intestinal wall, which can be life-threatening. Similarly, if you have a cough, consuming cough suppressants allows lung inflammation to continue and become potentially life-threatening.

Different Treatments Different Impacts
Because cancer treatments attack the disease in different ways, they may also affect the immune system in different ways. For instance:
Chemotherapy drugs are designed to kill fast growing cells, which most cancer cells are. But chemotherapy may also attack fast-growing healthy cells, such as those found bone marrow, which produces immune cells, hampering their ability to protect you from illnesses, bacteria and other threats.
Surgery, especially major surgery, may put a burden on the immune system, exhausting its reserves to help prevent infection and heal wounds caused by the procedure. Surgery requires cutting through the skin and layers of tissue, which may expose the body to germs. Also, surgeons may need to remove lymph nodes, which help fight infection.
Radiation therapy works by exposing cancer cells to ionizing waves of energy that kill the cells or stunt their growth. While destroying or damaging cancer cells, the treatment may also damage healthy cells and contribute to conditions that may lead to an increased risk of infection.
Immunotherapy drugs called checkpoint inhibitors are designed to boost the immune system by helping them to better recognize and attack cancer cells. But, in some cases, an overactive immune system may attack healthy cells and cause flu-like symptoms or potentially serious autoimmune conditions, such as colitis.
Are Cancer Survivors Immunocompromised
Patients with a history of cancer who are not currently on therapy and dont have active cancer are probably not at significantly increased risk compared to other people in their age group, Moore said.
Hormonal therapies for breast cancer are also not going to increase the risk of severe disease, she added.
The higher risk is for people currently receiving immune-suppressive treatment, as well as those who have active cancer and are not in remission.
Chemotherapy is going to raise risk more than radiation or surgery, but anything that stresses the system has the potential for increasing ones risk of infection, Moore said.
Its not clear how immunotherapy might impact the risk, but patients receiving it may develop symptoms and side effects that can be very difficult to distinguish from infection, she noted.

New Discoveries And Honors In Cancer Research
Read the latest cancer research and recognition from the members of the Damon Runyon scientific circle.
For decades, a weakened immune system has been considered an unavoidable side effect of receiving radiation or chemotherapy. These treatments, while highly effective at killing cancer cells, also deplete the bodys store of blood stem cells and damage the area in the bone marrow where new ones are produced. Blood stem cells, also known as hematopoietic stem cells , are critical for a functioning immune system because they give rise to all other blood cells, including white blood cells.
The antibody anti-NRP1 disrupts the cell death pathwaytriggered by radiation
But a shortcut to immune system recovery may be in sight. Last month, former Damon Runyon Fellow Christina M. Termini, PhD, and her colleagues at University of California, Los Angeles, uncovered the signaling pathway that leads to HSC death following cancer treatmentand demonstrated how to block it. The researchers found that, in response to cancer treatment, the bone marrow secretes a protein called Sema3A, a cell death signal known for killing excess neurons in the development of the nervous system. In this case, Sema3A induces cell death by attaching to a receptor on the surface of bone marrow cells known as NRP1. The team found that blocking this receptor with an antibody, appropriately named anti-NRP1, resulted in bone marrow cell survival. This, in turn, accelerated regeneration of HSCs.
Discuss Vaccine Options With Your Oncology Team
Its important to discuss vaccines with your oncology team. They can help to determine the best approach to your individual situation as far as which vaccines you should get and when.
If youve had chemotherapy, youll need to wait a little bit of time for your immune system to recover. To see if your WBC levels have risen, your oncologist will order a complete blood count before vaccination.
This test uses a sample of blood thats taken from a vein in your arm. It measures the levels of different types of blood cells, including WBCs, and can give your team an idea of your level of immune function.

How Soon After Treatment Finishes Will I Feel Better
It takes time to recover after treatment for lymphoma and it might take a while for your energy levels to build back up. How quickly you feel stronger depends on factors that include:
- the type of treatment you had
- whether side effects go on once you finish your treatment
- your general health and fitness, including any other medical conditions, if you have any
- how you feel emotionally.
Some people have side effects that go on after treatment finishes. If this is the case for you, ask your CNS or GP for advice about how to manage these.

Activities Of Daily Living
Mouth care. It is very important to brush your child’s teeth with a soft toothbrush at least twice a day as bacteria and yeast like to grow in the mouth. Your doctor may have your child continue with the chlorhexidine or heme/onc mouthwash, but it is still important to have your child brush his/her teeth. Avoid dental work until approved by your doctor. When your childs platelet count is normal, a regular toothbrush should be used.
Sun/ultraviolet rays: The chemotherapy and radiation that your child received makes the skin very sensitive to the sun so that your child may be sunburned with very little exposure. Sunlight can also make GVHD worse. Your child should avoid excessive direct exposure to sun, especially between 10 am and 4 PM, when the sun’s rays are strongest. If your child has to be in the sun, he should wear a hat, a shirt with long sleeves and long pants. Apply a sunscreen with at least a sun protection factor of 30, thirty minutes to one hour before going outside. Sunscreen should be reapplied frequently while your child is in the sun.
School re-entry. It is very important for your child to continue with school however, infections are easily transmitted in school rooms. We recommend that schooling be continued at home with homebound schooling during the first several months after leaving the hospital. This will vary from patient to patient so discuss this issue with your doctor. Your social worker can help you arrange your child’s homebound schooling.
Eat A Nutritious Diet
Poor nutrition can weaken your immune system. In turn, this raises your chances of getting sick. Thats why its so important to eat a nutritious diet with enough calories and nutrients to meet your bodys needs.
That can sometimes be tricky to do, especially if cancer or cancer treatments have affected your digestive system or appetite.
To develop an eating plan that works for you, your doctor might encourage you to meet with a nutritionist. In some cases, they might recommend dietary supplements, tube feedings, or intravenous feedings to help meet your nutritional needs.
Some germs can be spread through foods and drinks. To protect yourself, wash raw fruits and vegetables before eating them. Thoroughly cook all animal products, including meat, eggs, and dairy products.
of becoming ill by washing your hands regularly with soap and warm water, especially:
- before eating, blowing your nose, or touching your face
- after spending time in public places or with people who are sick
- after using the washroom, touching garbage, or handling animal products or waste
Use an alcohol-based hand sanitizer to clean your hands when theres no soap or water available.
Its also important to shower or bathe on a regular basis and brush your teeth every day.
Try not to spend time with people who have a fever, the flu, or other infections. If someone in your home is sick:
You should also try to avoid large crowds. Some people in a crowd may have viral or other infections.

Cancer Itself Can Increase Infection Risk
Some types of cancer can change the way the immune system blood cells work. For instance, lymphomas , multiple myeloma, and most types of leukemia start in immune system blood cells. Other types of cancer can also affect the immune system and its cells. They can change the immune system cells so that cells that once protected your body begin to interfere with the normal way your immune system works. Cancer cells can get into the bone marrow cells where blood cells are made. The cancer cells then compete with the normal bone marrow cells for space and nutrients. If too many normal bone marrow cells are destroyed or pushed out of the bone marrow, the few cells that are left won’t be able to make enough white blood cells to help the body fight infection.
Cancer can also damage other parts of the immune system. A tumor that grows on the skin or in mucous membranes can break natural barriers and allow germs to get in. Tumors that are large might reduce blood flow to normal tissues by pressing on them or their blood supply. Tumors in the lungs may block normal mucus drainage, which can lead to infections. And, other types of tissues that have been damaged by cancer can be more prone to infections.
