Intratumoral immunotherapy

4 Benefits of Intratumoral Immunotherapy for Cancer Patients

Intratumoral immunotherapy is one of the most recent scientific advances for cancer treatments. This discovery has had some amazing results, including eliminating traces of cancer cells within the patient’s body. 

This treatment is centered around the idea of using the tumor as the vaccine to fight against cancer. It entails directly injecting high concentrations of immunostimulatory products, coupled with a small amount of medication, into the tumor.

One study published in the journal The Oncologist has shown that the overall response rate of this treatment was 55 percent, in a treatment course done over 12 weeks. Those who underwent a second course had a 26% to 51% success rate. 

Here are five benefits to intratumoral immunotherapy:


1. It allows the tumor to work against itself

As the term suggests, intratumoral means inside the tumor. Experts believe that the most effective way to cure the disease is to use what’s already there — the tumor cells. 

Intratumoral immunotherapy works to optimize the cancer cells so that they can inhibit any tumor growth. At the same time, this therapy nudges the patient’s immune system so that it grows stronger to fight off cancer.  

The body’s immune system has the ability to kill cells or stop the spread of pathogens (disease-causing microorganisms) in the cells and organs. The goal of this revolutionary cancer treatment is to turn tumors into pathogen-infected tissues to become mediators and stop the spread of cancer cells. 


2. It has little side effects

Since this revolutionary cancer treatment makes use of what’s already there, there are potentially fewer side effects compared to other forms of cancer therapy. Treatment sessions become more bearable for cancer patients, most of whom develop an aversion to chemotherapy. 


3. It brings fewer financial burdens

Treatment sessions are also fewer than other types of cancer treatment, cutting the costs. For many patients burdened by the expense, this treatment is more practical while giving the patient a high chance of defeating the disease.


4. It works well with other therapies

Some patients may still prefer to undergo radiation and chemotherapy treatments. The good news is that they can combine these with intratumoral immunotherapy, giving the patient more chance of remission. 

In general, patients respond differently to different therapies. But a study has shown that combination treatments are safe, cost-efficient, and helpful to cancer patients, especially if they want a more targeted treatment plan. 

At Williams Cancer Institute, we offer intratumoral immunotherapy, cryoablation, and radiofrequency ablation for cancer to get the best results for our patients. If you’re considering a combination treatment, we strongly encourage you to talk to our doctors about your options.

radiofrequency ablation for cancer

Cancer is a leading cause of mortality around the world. It was responsible for the death of 9.6 million people in 2018 alone. In Thailand, around 70,000 to 100,000 people die from cancer every year, while in Qatar, it is the third-leading cause of death.

Research has shown that the five most common types of cancer in Thailand are liver, breast, cervical, lung, and colorectal cancer. In Doha, breast cancer has the bulk of the cases at 30.1%, but lymph node, thyroid, lung, and genital cancers are also occurring among men and women aged 65 and over, according to the Asian Pacific Journal of Cancer

Intratumoral Immunotherapy

Intratumoral Immunotherapy is considered to be a revolutionary cancer treatment. It triggers the local and systemic immunologic responses of the body against tumor cells. The word ‘intratumoral’ means that the antibodies are directly injected into the cancer tumors, rather than through the vein (intravenous immunotherapy). 

Experts believe that the way to beat cancer is to strengthen the body’s immune defenses. The therapy works to nudge the cancer patient’s immune system and target the cancer cells to be killed off before the condition worsens and cancer overruns the body. Simply put, intratumoral immunotherapy works like a vaccine that optimizes the cells in the body to inhibit malignant growth. 

Cryoablation with Immunotherapy

Cryoablation entails freezing the tumor tissues so that they can be easily destroyed by necrosis and osmosis. According to journal Insights to Imaging, cryoablation has to be combined with immunotherapy to enhance the effects of killing the tumors.

Freezing the tumor can help release antigens in the immune system that would pave the way for improving the anti-tumor immune responses of the cancer patients. Immunotherapy, on the other hand, nudges the immune responses to eradicate the tumors.

Intravenous Immunotherapy combined with Intratumoral Injection of Immunotherapy

Also regarded as more comprehensive immunotherapy, this treatment is an enhanced version of the intratumoral injection augmented by other off label medications for the immune system. This can be combined with chemotherapy or other cancer treatments, depending on the doctor’s recommendations and evaluation. 

advanced cancer treatment thailand & dohaAdvanced Cancer Treatment in Thailand

In Thailand, cancer treatments mainly follow the same regulations and directives as to the U.S. Food and Drug Administration (FDA) or European Medicines Agencies. But the country is also a leader in developing its advanced cancer treatments using immunotherapy.

A recent study from the experts at Chulalongkorn Hospital has shown that Thailand has made successful steps in this regard by curing certain blood cancers using “killer cells” during immunotherapies. However, the experts said they would need more studies on applying immunotherapy to solid cancerous tumors. 

The cost of immunotherapy in Thailand is about 300,000 baht per dose or up to 8 million baht. Experts are developing their own locally-produced biologic drugs so that everyone can afford alternative cancer treatments in Thailand

In Thailand, liver cancer is the number one cause of cancer-related deaths. In 2018 alone, there were 23,296 new cases of liver cancer in the country. Prostate cancer is the 12th leading cause of cancer-related deaths in Thailand, which recorded a total of 6,467 new cases in the same year.

Thailand has over 90,000 deaths due to cancer among a total population of 70 million. The country also has its own cancer strategy plan, but it only works at the national level. Therefore, many cancer patients and their families still need to shoulder the cost of advanced cancer treatments despite being widely available. 

Advanced Cancer Treatment in Doha 

Alternative cancer treatments in Doha, Qatar are actually free for all residents at the Hamad Medical Corporation. The state used to cover 80% of the oncology treatments, but this has now been 100% absorbed by the state.

The cases of cancer in Doha are low compared to global statistics, as Qatar only has less than two million people in the population. More male patients, however, are vulnerable to the deadly disease than females.

Cancer immunotherapy treatments are integrated into other treatment modalities like surgery, chemotherapy, or radiotherapy. In some cases, it can also be used as the first line of treatment or standalone management.

Every patient’s case is different. Explore your options by talking to our doctor at Williams Cancer Institute.

Advantages of Intratumoral Immunotherapy in Cancer Treatment

Intratumoral immunotherapy is a revolutionary cancer treatment that makes use of sophisticated antibodies, which are directly injected into the cancer tumors, instead of intravenously.

This new cancer treatment immunotherapy can dramatically improve a cancer patient’s response rate, along with many other advantages.

Tumor against itself

The word itself, intratumoral, means within a tumor. Experts think that the best way to cure cancer is to use what’s already in the patient’s body, which means using cancer against itself. 

A cancer patient’s immune system may target cancer cells and kill them before they overrun the body. However, the immune system sometimes needs a little nudge and this is where intratumoral immunotherapy could help. 

According to experts, intratumoral immunotherapy optimizes cancer cells to work like a vaccine. It also inhibits the growth of the tumor as the tumor cells are injected with antibodies.

This process allows the patient to have cancer treatments with few side effects, unlike other methods. This also cuts the cost of expensive cancer treatments, while giving patients higher chances of survival and longer life.

How Does Intratumoral Immunotherapy Work? 

After the ablation of the tumor deposits either by heating or freezing, any non-viable cells that remain in the patient’s body may be used to stimulate the immune system with intratumoral immunotherapy. Doctors will use an -OX40 agonist combined with other types of cancer medication or vaccine — such as CpG, ipilimumab, and ketorolac — for the therapy, as in the case of stage 4 breast cancer patient with two liver metastases. 

In this case, following the therapy, a CT scan was performed on the patient six weeks after the procedure, and a positron emission tomography (PET) scan with a CT scan was also done 12 weeks after the therapy. The results showed that the cancer tumors were no longer found in the body, and the liver metastases had rescinded. 

Can Intratumoral Immunotherapy Work With Other Therapies?

Patients who are undergoing intravenous immunotherapy may consider intratumoral immunotherapy to enhance their treatments or add this to their radiation treatments or chemotherapy. According to experts, combination treatments are actually helpful, cost-effective, and safer for cancer patients since the therapy is more targeted. Furthermore, the effects of immunotherapy and ablation, when combined, are synergistic.

Cancer treatments, in general, open different challenges both in the clinical and economic sense. Some patients also respond better to specific therapies than other patients. We strongly encourage patients to discuss their options thoroughly with our doctors at Williams Cancer Institute before proceeding with the treatments.

Antibiotic use before cancer treatment cuts survival time study

4 Oct 2019 Cancer, Immunotherapy

We have discussed this before. It is becoming standard in our patients to not only evaluate the microbiome with Microbiome Dx, but also patients with recent antibiotic use prior to immunotherapy probably will need a fecal microbiota transplant (FMT).

Taking antibiotics in the month before starting immunotherapy dramatically reduces a cancer patient’s chances of survival, according to a small but groundbreaking study.

Scientists at Imperial College London believe antibiotics strip out helpful bacteria from the gut, which weakens the immune system. This appears to make it less likely that immunotherapy drugs will boost the body’s cancer-fighting capability.

MDSC targeting with Gemtuzumab ozogamicin restores T cell immunity and immunotherapy against cancers

2 Sep 2019 Immunotherapy

There are numerous reasons for immunotherapy to fail or for cancer in general to be able to fight against your body and survive. One important mechanism is Myeloid Derived Suppressor Cells (MDSC). These are immune cells that can actually protect cancer. As described in this article, a new method to target these using a drug that is already FDA approved (Mylotarg) can enhance the success of immunotherapy such as immune check-point inhibitors (Keytruda, Opdivo, Yervoy) and also CAR-.

Is Immunotherapy for Cancer Safe?

Your immune system does more than simply fight colds and flu. Throughout your life, your natural defenses seek out and destroy anything that is not recognized as part of the self including all kinds of germs and cancer cells before they have a chance to cause disease. Your immune system manages to destroy most rogue cells before they form a full-fledged tumor, but some of them get by your defenses. If you already have cancer, your immune system will still be working hard to keep your disease in check, but it probably can’t do the job on its own.

In recent years, more and more cancer patients have received treatments designed to give the immune system the upper hand against cancer. This approach called immunotherapy or biological therapy isn’t as widely used as radiation or chemotherapy. For most types of cancer, immunotherapy hasn’t been shown to be more effective than these standard treatments. And like the others, it can cause its own unpleasant side effects.

But immunotherapy can still be a powerful tool, either on its own or combined with chemotherapy or radiation. For certain patients including some in the advanced stages of skin cancer or kidney cancer immunotherapy can offer more than the conventional options, even the possibility of a complete cure. For others, it’s an additional, less toxic method of controlling their disease or reducing side effects from other treatments. In the years to come, as scientists learn more about the immune system, immunotherapy promises to become even more common and more effective.

What does it involve?

Immunotherapy often involves adding more immune cells, immune signaling molecules, or other biochemicals to the body. Unlike chemotherapy, which affects all fast-growing cells, immune treatments target specific processes or types of cells and should have a low impact on healthy tissues. The side effects depend on the particular biological agent used. Some have very mild side effects, while others cause serious problems.

The delivery will also depend on the agent used as well as your treatment plan. Some immunotherapy treatments are in the form of pills or shots you can take at home, while others are delivered intravenously (IV) in the hospital or clinic. Immunotherapy may be administered a couple of times a day or as seldom as every month or two.

What are the different types of immunotherapy?

There are two major types of immunotherapy: Treatments that add new disease-fighting cells to your body (T cells) and treatments that add other elements to your own immune system (such as antibodies, cytokines, and others). Many immunotherapy agents are experimental or investigational and are only available by enrolling in clinical trials.

How will my doctor decide if immunotherapy is right for me?

Not all patients or all cancers are good candidates for immunotherapy. At this time, the approach isn’t used very often for patients with cancer of the prostate or ovaries. And if your cancer was caught at an early stage or is responding well to other treatments, immunotherapy may simply not be necessary.

In certain cases, however, immunotherapy does seem to be more effective when used for some smaller, earlier-stage cancers. If your doctor does recommend immunotherapy, you will be getting a cutting-edge treatment that could make a big difference.

Immunotherapy to Treat Cancer

Immunotherapy to Treat Cancer

Immunotherapy is a type of cancer treatment that helps your immune system fight cancer. The immune system helps your body fight infections and other diseases. It is made up of white blood cells and organs and tissues of the lymph system.

Immunotherapy is a type of biological therapy. Biological therapy is a type of treatment that uses substances made from living organisms to treat cancer.

How Immunotherapy Works against Cancer

One reason that cancer cells thrive is because they are able to hide from your immune system. Certain immunotherapies can mark cancer cells so it is easier for the immune system to find and destroy them. Other immunotherapies boost your immune system to work better against cancer.

Immunotherapy Can Cause Side Effects

Immunotherapy can cause side effects, which affect people in different ways. The side effects you may have and how they make you feel will depend on how healthy you are before treatment, your type of cancer, how advanced it is, the type of therapy you are getting, and the dose. Doctors and nurses cannot know for certain how you will feel during treatment.

The most common side effects are skin reactions at the needle site. These side effects include:

  • Pain
  • Swelling
  • Soreness
  • Redness
  • Itchiness
  • Rash

Immunotherapies may also cause severe or even fatal allergic reactions. However, these reactions are rare.

Where You Go for Your Immunotherapy Treatment

You may receive immunotherapy in a doctor’s office, clinic, or outpatient unit in a hospital. Outpatient means you do not spend the night in the hospital.

Contact Us to know more.

How Often You Will Receive Immunotherapy Treatment

How often and how long you receive immunotherapy depends on:

  • Your type of cancer and how advanced it is
  • The type of immunotherapy you get
  • How your body reacts to treatment

You may have treatment every day, week, or month. Some immunotherapies are given in cycles. A cycle is a period of treatment followed by a period of rest. The rest period gives your body a chance to recover, respond to the immunotherapy, and build new healthy cells.

How to Tell Whether Immunotherapy Is Working

You will see your doctor often. He or she will give you physical exams and ask you how you feel. You will have medical tests, such as blood tests and different types of scans. These tests will measure the size of your tumor and look for changes in your blood work.

Who Receives Immunotherapy

Immunotherapy is not yet as widely used as surgery, chemotherapy, and radiation therapy. However, immunotherapies have been approved to treat people with many types of cancer.

How Cancer Affects Your Immune System and What to Do About It

It’s perhaps your biggest ally in helping your body fight disease. And understanding how your immune system joins forces with cancer treatment can give you a positive advantage.

Basically, your immune system targets disease and infection. It detects and destroys anything it sees as a threat.

  • Bacteria
  • Viruses
  • Parasites


  • Unhealthy cells including cancer cells!

The question perhaps you and everyone asks

Having a strong immune system should reduce your body’s vulnerability to illness and disease, right? So why do you still get sick?

Or receive a cancer diagnosis?

Your body’s immune system “highway”

The lymphatic system is a network of vessels and tissues. It collects and transports excess fluids (including some fats) from other tissues throughout your body. It then provides them access to your bloodstream.

There’s a close connection between your lymphatic system and your immune system.

Many of the disease-fighting cells of the immune system: Begin in the bone marrow. Mature in the thymus. Are stored in strategic locations. Use the lymphatic “highway” system to travel through the body, and along with the lymph nodes and spleen filter out harmful materials and germs. An immune response occurs when the immune system is activated and responds. This can occur when a foreign invader is detected.1

How cancer takes advantage of your immune system

Theories abound. One is that your immune system attacks cells it views as foreign. And cancer cells start out as normal (looking) cells.

Any changes the cancer cell makes within can still appear normal to your immune system. The mutation can occur, the cells can grow and multiply, and no attack is launched to destroy them.

Cancer cells can turn off your body’s natural immune response and suppress the activity of local immune cells (which protect a specific organ or other part of the body). Within the tumor, the cancer cells can create an environment that interferes with the effectiveness of the immune response. 2

There are multiple layers to the somewhat covert attack of cancer cells on your body’s immune system. This makes it all the more necessary that you give yourself an advantage when receiving a cancer diagnosis.

A counter-attack on cancer

The ability of cancer to hide from your body’s natural, disease-fighting immune system calls for new strategies. Immunotherapy helps your immune system by strengthening or restoring its ability to fight cancer.


  • Stops cancer from spreading (metastasizing)
  • Increases your immune system’s cancer-killing efficiency
  • Reduces the speed or progress of cancer’s growth
  • Delivers therapies directly into cancer cells

Questions about immunotherapy and its unique relationship with your body’s immune system are important to your cancer fight. We’re experienced and prepared to provide you the answers you need about this unique and effective cancer treatment.

What to Know About Common Immune Checkpoint Inhibitors

Your body is a fascinating organism. Cell to cell your immune system is capable of identifying normal cells and those it considers foreign and potentially harmful.

Checkpoint inhibitors are vital to helping treat cancer.

The basics of how it works: Your immune system responds by attacking the foreign cells and protecting the normal cells.

A whole new level of cancer treatment

What happens on the molecular level in your body is equally fascinating. Checkpoints on certain cellular molecules can be activated or inactivated to compel an immune response.

On the other hand, cancer cells can innovate and use these same checkpoints to avoid an attack by your immune system. This is where strategic drug therapies can be aimed at those checkpoints to give your cancer treatment an advantage.

Like an “off-switch”

Without getting too technical, meet PD-1. This particular checkpoint protein resides on your body’s immune cells called T-cells.

Think of it like an “off-switch”. It helps prevent T-cells from attacking your body’s other cells.

PD-1 joins with the protein, PD-L1, that lives on some normal (and cancer) cells in your body. Their joint effort sends a clear message to the T-cell that it should not mess with the other cell.

Cancer cells can have large amounts of PD-L1. This helps them be evasive against an immune system attack.

Certain antibodies can effectively target PD-1 or PD-L1 and block their joint defensive effort. This boosts your immune response against cancer cells.

Meet the immune checkpoint inhibitors that work

Keytruda (Pembrolizumab)

A Behind-the-Scenes Look at Immunotherapy

Cancer can cause a fight-or-flight response. Fear is normal. After all, who isn’t afraid when they hear the diagnosis?

Even so you can still bring the fight to it.

Your Body’s Unique Ability to Fight Cancer

Immunotherapy is in your corner. Basically, the treatment stands alongside your immune system to help your body fight cancer.

It functions the same way as your immunity does helping your body fight infections and other diseases. Its special forces include your white blood cells, your organs, and the tissues that make up your lymph system.

Biological therapy is another way to describe immunotherapy. Think of it as treating and defeating cancer with living organisms.

Attack Strategy

Cancer’s strategy is to hide from your immune system. Specific immune strategies call-out cancer cells and mark them as a target for destruction.

Immunotherapy is a counter-attack that can be used in a variety of ways. Each have a specific impact on cancer.

Checkpoint inhibitors
These drugs join your immune system for the strong assault on a tumor. They release the brakes that hold white blood cells back from killing cancer cells. The drugs run interference on cancer cells to prevent them from avoiding the attack of your immune system.

Cell transfer
This treatment strategy brings-out-the-fight in your T-cells natural ability to battle cancer. Cells are directly removed from your tumor. The active ones are ultimately used in the fight against the cancer.

Treatment vaccines
These battle cancer as they energize your immune system’s response to cancer cells. Its a different brand of vaccine than is used to help prevent disease.

Collateral Impact

Immunotherapy is effective. But side-effects are also common.

  • Skin reactions at injection site can include some pain, swelling, soreness, or a rash that’s red or itches.
  • Flu-like symptoms might occur such as fever, chills, weakness, dizziness, nausea/vomiting, muscle aches, fatigue, and headache.
  • Other side-effects are low or high blood pressure, weight gain from fluid retention, sinus congestion, some allergic reactions (though rare), and heart palpitations.

Your initial health, the stage of cancer, and type of therapy are factors in the side-effects you experience.

Keep in mind that routine doctor visits will monitor your progress with immunotherapy. Medical tests (including blood tests) and a variety of scans will measure the tumor’s size and any changes in blood work.
