Other Immunotherapies For Metastatic Melanoma

Immunotherapy – the new treatment for cancer.

In looking forward for approaches to improve therapeutic outcomes, reviewing past development efforts of other immune modulators is instructive. Because of its presumed immunogenicity, most immune modulators were tested initially in metastatic melanoma. Using objective response as the measure of clinical activity, most agents were either inactive or at best demonstrated low response rates. Immune modulators tested in clinical trials included cancer vaccines, cytokines, costimulatory receptor agonists, and multiple types of cell therapies.

Many types of cancer vaccines progressed to clinical development, immunizing against shared melanosomal proteins or cancer-testes antigens, or against antigens contained in autologous tumor or allogeneic tumor cells. Multiple antigen delivery approaches and immunologic adjuvants were employed in the vaccine trials, including gene-modified cells, peptides or proteins with adjuvant, antigen loaded onto autologous dendritic cells, and delivery of defined antigens by viral vectors or DNA plasmids . Rare responses of small-volume distant metastatic disease were observed in some of these trials. Vaccine development is currently focused on immunization against autologous neoantigens defined by whole-exome sequencing or RNAseq combined with bioinformatics analyses to predict binding of peptide sequences containing the mutation to the patient’s HLA molecules . All older vaccine trials in the adjuvant setting have failed to improve RFS or OS.

When You Might Have Targeted Cancer Drugs Or Immunotherapy

You might have targeted cancer drugs or immunotherapy for some stage 3 melanomas to help reduce the risk of the cancer coming back.

Stage 3 generally means that the melanoma has only spread to the nearby lymph nodes or to an area between the primary melanoma and the nearby lymph nodes. You might have targeted cancer drugs or immunotherapy:

  • if melanoma cells are found in your lymph nodes after a sentinel lymph node biopsy
  • after surgery to remove your lymph nodes or in-transit metastases

In-transit metastases are areas of cancer that have spread more than 2cm from where the melanoma started but not as far as the nearby lymph nodes.

Or you might have targeted cancer drugs or immunotherapy for melanoma that cant be removed with surgery . Or if it has spread to another part of the body .

When Should I Call The Doctor

Everyoneâs different, so thereâs no rule for when side effects will show up. Skin problems can appear 2 to 3 weeks after the first dose of the drug, gastrointestinal problems may take 6 to 7 weeks, and endocrine problems may not affect you for more than 2 months. Some people donât have side effects until months after treatment ends.

The good news: Most side effects go away when youâre done. But even during treatment, there are ways to manage them. Let your doctor know so they can help.

Tell them how the symptoms are affecting your daily life. Donât feel like youâre complaining. You arenât. Youâre sharing vital information they need to do their job well and to improve your quality of life.

Heat Shock Peptide Vaccines In Melanoma Immunotherapy

A recent approach consists of using heat shock protein-peptide complexes as vaccines. Heat shock proteins are stress proteins that “chaperone” antigenic proteins, alerting the immune system to eliminate the disease.

Peptide complexes extracted from melanoma cells can stimulate antigen-specific CD8+ T cells in the peripheral blood of melanoma patients. Preliminary data have indicated feasibility, minimal toxicity, and clinical responses in 18% of patients along with tumour-specific T-cell responses in 50% to 60% of subjects.

Currently, a phase III study is comparing a heat shock peptide vaccine derived from autologous tumour to standard therapies in stage IV melanoma patients.

Surgery for a primary melanoma Stages 0-I-II

For patients in stage 0, I or II, surgery of a primary melanoma includes, but may not be limited to, the removal of the primary tumour with a margin of normal skin.

Excision margins involve the removal of normal skin and flesh from around the primary tumour with the aim of ensuring any residual cancer cells have been removed. The margin of skin and fat relates to the thickness of the tumour. For a Level 1, in situ melanoma the margin should be 0.51.0cm. For stage III melanoma the margin should be between 1-2cm. Sentinel lymph node biopsy is considered in patients with Stage Ib IIc primary melanoma.

A skin graft or a skin flap may be required after the removal of the melanoma. After the surgery, a pathologist determines whether margins are clear by examining the entire specimen and the excised tumour edges.

Genetic Testing Of Your Melanoma

If you are diagnosed with stage 3 or 4 melanoma, your doctor sends a sample of the melanoma for genetic testing. This is to look for changes in genes including the BRAF gene. This genetic change makes the melanoma cells produce too much BRAF protein, which can make melanoma cells grow.

About 40 to 50 out of every 100 people with skin melanoma have a change in the BRAF gene.

If you have changes in the BRAF gene, doctors describe your melanoma as BRAF positive. If you dont have changes, then your melanoma is BRAF negative. Knowing this can help your doctor make decisions about whether it would be helpful to give you targeted cancer drugs.

The Future Of Immunotherapy

Terry’s story shows the powerful effects, as well as the challenges, associated with immunotherapy. It is a relatively new treatment, and we continue to refine it and use it in new ways. Weve seen how it works against melanoma, as well as kidney cancer and lung cancer.

And while immunotoxicities are not what we want, there is some data to suggest that patients who get them are more likely to respond to the treatment. We dont know exactly why, and through clinical trials we are working to prevent side effects while continuing to reap the benefits of immunotherapy.

Clinical trials offer gold standard of care plus the newest available treatments, often at little to no cost to patients. These studies help us advance treatment options for more patients.

If you or a loved one is diagnosed with metastatic melanoma, ask your doctor about immunotherapy. Find an academic medical center that has teams of experts in place not only to manage your care, but also the potential side effects of treatment.

Weve only scratched the surface of what immunotherapy can offer cancer patients. But at UT Southwestern and Simmons Cancer Center we are determined to continue improving it to help more patients like Terry beat this disease and lead longer, healthier lives.

How Does Immunotherapy Treat Mesothelioma

Immunotherapy treatments work by enhancing the immune system response to mesothelioma cancer cells. However, it is not used to cure the cancer. Mesothelioma has no cure, but therapeutic options like immunotherapy may help patients extend life expectancy.

Mesothelioma immunotherapy treatments may have a few main goals, including:

  • To reduce the possibility of cancer recurrence
  • To maximize the efficacy of first-line treatments, such as chemotherapy and radiation
  • To extend patient life expectancy after first-line treatments

Researchers continue to test immunotherapy treatments for mesothelioma and other cancers. As medical research for immunotherapy continues, the success and limitations of the treatment could become more clear.

Treating Stage 3 Melanoma


If the melanoma has spread to nearby lymph nodes , further surgery may be needed to remove them.

Stage 3 melanoma may be diagnosed by a sentinel node biopsy, or you or a member of your treatment team may have felt a lump in your lymph nodes.

The diagnosis of melanoma is usually confirmed using a needle biopsy .

Removing the affected lymph nodes is done under general anaesthetic.

The procedure, called a lymph node dissection, can disrupt the lymphatic system, leading to a build-up of fluids in your limbs. This is known as lymphoedema.

Cancer Research UK has more information about surgery to remove lymph nodes.

Treating Stage 1 To 2 Melanoma

Treating stage 1 melanoma involves surgery to remove the melanoma and a small area of skin around it. This is known as surgical excision.

Surgical excision is usually done using local anaesthetic, which means you’ll be awake, but the area around the melanoma will be numbed, so you will not feel pain. In some cases, general anaesthetic is used, which means you’ll be unconscious during the procedure.

If a surgical excision is likely to leave a significant scar, it may be done in combination with a skin graft. However, skin flaps are now more commonly used because the scars are usually less noticeable than those resulting from a skin graft.

Read more about flap surgery.

In most cases, once the melanoma has been removed there’s little possibility of it returning and no further treatment should be needed. Most people are monitored for 1 to 5 years and are then discharged with no further problems.

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.

Immunotherapy: What You Need To Know

Not all that long ago, chemotherapy was the only option to treat most advanced cancers. Because these drugs work by destroying rapidly dividing cells, they harm some healthy cells such as hair follicles as well as cancer cells. In the past two decades, cancer treatment has been transformed by targeted drugs and the emergence of immunotherapy. Targeted drugs are designed to home in on specific genes or proteins that are altered or overexpressed on cancer cells. Immunotherapy has been very successful for certain types of advanced cancers, such as lung, bladder, and skin cancers.

One form of immunotherapy is called an immune checkpoint inhibitor. It takes the brakes off immune cells, unlocking their ability to detect altered proteins on cancer cells in order to attack and kill these cells. These drugs include programmed death -inhibitors and PD-L1-inhibitors , and cytotoxic T-lymphocyte antigen -4 inhibitors .

The speed of FDA approvals for these drugs has outstripped the general understanding of their effects, and side effects, raising many questions for people who have cancer and even for many physicians. If youre receiving immune checkpoint inhibitors, or wondering about them as part of cancer therapy, here are some facts you should know.

Is Immunotherapy A Last

How Cancer Immunotherapy Is Getting Even Better

Not necessarily. Different cancer treatment guidelines suggest that immunotherapy medications can be used in a variety of situations. They might be preferred options, last-choice options, or somewhere in between. It depends on your cancer.

For example, immunotherapy medications like pembrolizumab and atezolizumab are often first-choice options for metastatic nonsmall cell lung cancers that have a high amount of PD-L1. PD-L1 is a protein that can be found on cancer cells. A biomarker test determines if you have high, low, or no PD-L1. They can be used alone or in combination with chemotherapy medications like carboplatin and pemetrexed .

But this isnt always the case. There are times when immunotherapy medications are used if a first- or second-choice treatment didnt work as well as intended.

For example, surgery is often an ideal way to treat certain types of melanoma, a form of skin cancer. But if cancer cells are still around after surgery, immunotherapy medications like pembrolizumab or nivolumab might be given to you.

There are countless other situations where immunotherapy medications could be used. They could be used in situations like the ones described above, or they could be used only after other medications are unsuccessful.

Depending on your cancer, medical history, and potential results of tests like biomarker tests, your cancer specialist can decide if immunotherapy is a viable option for you.

An Exception: Autoimmune Disorders

If you have an autoimmune disorder, you may be unable to tolerate immunotherapy even if you would otherwise qualify for treatment. With an autoimmune disease, such as lupus, rheumatoid arthritis, Crohns disease or ulcerative colitis, your immune system mistakenly attacks healthy cells. Autoimmune diseases are treated with drugs that suppress the immune system. Immunotherapy, on the other hand, revs up the immune system and stimulates T-cells. So, immunotherapy may cause your autoimmune disease to flare up, or it may produce other toxic side effects. A potent immune response may even cause your T-cells to start attacking your organs.

Symptoms of an autoimmune response to immunotherapy may include diarrhea, inflammation of the liver, a skin rash or inflammation of the lung. Sometimes, we may be able to successfully treat the flare-up and continue immunotherapy. For example, if you develop symptoms of hypothyroidism, but you respond to treatment for the condition, we may be able to continue immunotherapy.

A new clinical trial, sponsored by the National Cancer Institute , is testing the use of an immunotherapy drug on cancer patients who have a preexisting autoimmune disease when the risks of cancer outweigh the potential harms of an autoimmune response. So, while having a known autoimmune disease may disqualify you from receiving immunotherapy, advances in treatment research may eventually change that.

Which Cancers Are Treated With Immunotherapy

Immunotherapy drugs have been approved to treat many types of cancer. However, immunotherapy is not yet as widely used as surgery, chemotherapy, or radiation therapy. To learn about whether immunotherapy may be used to treat your cancer, see the PDQ® adult cancer treatment summaries and childhood cancer treatment summaries.

What Is Stage 4 Melanoma

Melanoma is a type of skin cancer that develops in the pigment cells of skin. It often starts out as a dark spot or mole.

In stage 4 melanoma, the cancer has spread from skin to other organs, such as the liver, lungs, brain, or gastrointestinal tract. It may also mean that the cancer has spread from the spot where it started to distant parts of your skin.

Stage 4 melanoma is harder to treat than less advanced stages of the cancer. However, treatment may still help improve your quality of life, your chances of survival, or both.

Treatment options for melanoma include:

  • immunotherapy
  • radiation
  • chemotherapy

Your doctors recommended treatment plan will depend on several factors, such as your overall health and where the cancer has spread in your body.

Immunotherapy involves the use of medications to stimulate your immune system. This may help it attack cancer cells.

Several types of immunotherapy are used to treat stage 4 melanoma, including:

Your doctor might prescribe one type of immunotherapy or a combination of immunotherapy drugs. For example, they might prescribe Yervoy and Opdivo together.

Immunotherapy has helped improve survival rates for people with stage 4 melanoma. However, this treatment can cause potentially serious side effects.

If you think you might be experiencing side effects, contact your doctor right away.

How Often Do You Receive Immunotherapy

Immunotherapy and melanoma

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 types of immunotherapy 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 immunotherapy, and build new healthy cells.

Combination Treatment Yervoy And Opdivo

Opdivo and Yervoy target different checkpoint pathways to boost the immune systems response to cancer.

When used together, they have a complementary effect. In summary, Yervoy builds the T-cell army and Opdivo unleashes the T-cell army against the tumour.

Sometimes, in this process, the T-cells may cause inflammation of healthy cells and may result in serious side effects. More people experience serious side effects when treated with the combination of Opdivo and Yervoy than single agent treatment. Side effects are generally manageable, if appropriately identified and treated. Healthcare professionals use established guidelines to treat these side effects and the earlier the side effect is identified and treated, the better. It is important that patients tell their healthcare professionals about any side effects, even if they seem minor, as inflammation may cause serious damage to your body and some inflammatory conditions may be life-threatening.

When used in combination:

  • Opdivo and Yervoy are administered together for the first four treatments, every 3 weeks
  • Opdivo is then administered on its own every 2 or 4 weeks
  • Treatment is stopped if the cancer progresses or there are unacceptable side effects.

The combination Yervoy and Opdivo is listed on the Pharmaceutical Benefits Scheme as a first-line treatment for melanoma patients with advanced disease who are BRAF positive.

Ganglioside Vaccines In Melanoma Immunotherapy

Defined tumour antigens may be created synthetically. Several cell-surface molecules on melanoma cells may be targeted by antibodies, and antibodies to some of these molecules are induced in patients with melanoma.

A series of clinical studies have been performed with vaccines intended to induce humoral or B-cell responses to the melanoma antigen, GM2, a cell-surface ganglioside. In a pilot study, Livingston and colleagues showed a trend toward improved survival for patients with stage III disease who received GM2 ganglioside/BCG and low-dose chemotherapy, and they demonstrated that patients developed antibodies to the GM2 ganglioside. This led to a larger randomised phase III ECOG study comparing GM2/KLH in saponin-derived adjuvant QS-21 vaccine to high-dose interferon -2b. This study was recently closed due to higher survival rates in those treated with adjuvant IFN -2b.
