Each year, Science magazine announces one pivotal scientific achievement as the “Breakthrough of the Year.” Memorial Sloan Kettering researchers have played a leading role in pioneering this year’s winner: cancer immunotherapy.

“Immunotherapy marks an entirely different way of treating cancer — by targeting the immune system, not the tumor itself,” Science said in choosing this burgeoning field. Based on the idea that the immune system can be trained to attack tumors in the same way that it targets infectious agents, cancer immunotherapy exploits the ability to harness different types of immune cells circulating in the body.

A Rich History at Memorial Sloan Kettering

Although cancer immunotherapy is being touted as a recent breakthrough in cancer treatment, its origins at Memorial Sloan Kettering go back more than a century. In the 1890s, William Coley, a surgeon at New York Cancer Hospital (the predecessor to Memorial Sloan Kettering) discovered cancer patients who suffered from infections after surgery often fared better than those who did not. His finding led to the development of Coley’s toxins, a cocktail of inactive bacteria injected into tumors that occasionally resulted in complete remission. But eventually the use of this treatment fell out of favor.

In the 1960s, research by Memorial Sloan Kettering investigator Lloyd Old led to the discovery of antibody receptors on the surface of cancer cells, which enabled the development of the first cancer vaccines and led to the understanding of how certain white blood cells, known as T cells or T lymphocytes, can be trained to recognize cancer.

Helping Patients Today

One of the pivotal milestones cited in the Science article is the work of immunologist James Allison in identifying a protein receptor on the surface of T cells called CTLA-4, which puts the brakes on T cells and prevents them carrying out immune attacks. He later identified an antibody that blocks CTLA-4 and showed that turning off those brakes allows T cells to destroy cancer in mice. (Dr. Allison, who spent nearly a decade of his career at Memorial Sloan Kettering until last year, is now at MD Anderson Cancer Center in Houston.)

Anti-CTLA-4 eventually became ipilimumab (YervoyTM), a drug approved in 2011 for the treatment of metastatic melanoma, the most deadly form of skin cancer. Dr. Allison, together with Memorial Sloan Kettering physician-scientist Jedd Wolchok, helped guide the development of ipilimumab from the first laboratory studies through the late-stage clinical trials that led to the drug’s approval.

Dr. Wolchok’s research on immune therapies for melanoma continues, including a study earlier this year that found that more than half of patients with advanced skin melanoma experienced tumor shrinkage of more than 80 percent when given the combination of ipilimumab and the antibody drug nivolumab, another promising immunotherapy drug under investigation, suggesting that these two drugs may work better together than on their own.

The other major area of research highlighted in the Science story is the development of chimeric antigen receptor (CAR) therapy, based on the idea that a patient’s own immune cell type, called T cells, can be collected from blood, engineered to recognize cancer cells and acquire stronger antitumor properties, and reinfused to circulate through the bloodstream and attack those cancerous cells. Memorial Sloan Kettering has been a leading center in developing this technology.

The first successes in this field have come in the treatment of leukemia. In March, Memorial Sloan Kettering investigators reported that genetically modified T cells had been successful in rapidly inducing complete remissions in patients with relapsed B cell acute lymphoblastic leukemia (ALL), an aggressive form of blood cancer.

“This is a very exciting finding for patients with B cell ALL, directly borne out of our basic research on CARs for over a decade, and a landmark proof of concept in the field of targeted immunotherapy,” says Michel Sadelain, Director of Memorial Sloan Kettering’s Center for Cell Engineering, who led the study, along with medical oncologist Renier Brentjens.

Memorial Sloan Kettering continues to study this approach and now has clinical trials under way investigating it in other types of leukemia, lymphoma, and prostate cancer, with several more trials slated to begin soon.

Looking toward the Future

Today, investigators in Memorial Sloan Kettering’s Immunology Program in the Sloan Kettering Institute are conducting a diverse range of studies aimed at developing the next generation of immune-based cancer treatments.

For example, Immunology Program Chair Alexander Rudensky is focused on studying a subset of T lymphocytes called regulatory T cells, which are critical for keeping other white blood cells in check and therefore play an important role in controlling immune system reactions. Understanding how these cells function, and how to inhibit them will offer novel and effective ways to treat cancer.

The research also has implications for treating conditions characterized by an overactive immune system — including autoimmune disorders such as rheumatoid arthritis, psoriasis, and diabetes.

IS HERCEPTIN therapy for sensitive ductal carcinoma of the breast a form of immunotherapy ?

Dear K Okail, thank you for your question. Herceptin is not a form of immunotherapy because it does not work by harnessing a person’s immune system to fight the disease. Rather, Herceptin is a type of drug called a targeted therapy that works by targeting specific molecules involved in the development of breast cancer. You can learn more about targeted therapies for breast cancer here: Thank you for your comment.

My father had a diagnostic of lung cáncer with no posibility of surgiral intervention.
The type of cáncer is epitelial cell, no small cells.

Hello there,

I have recently heard about how immunotherapy can help to minimize the risk of recurrence.

My husband was diagnosed with malignant fibrous histocytoma in July 2011. He had a surgery to remove the tumor in Aug'11 followed by 36 times radiotherapy.

In Dec 2012, his cancer mets to his lungs; (1 huge in LULL, 1 tiny in RULL & 2 tiny in RLLL). He then went for 6 cycles of chemo (epirubicin & ifosfamide), 2 times of lobectomy to remove the remaining tumors and another 36 times of radiotherapy.

In May 2014, PET scan image showed tiny new lesion on his left thigh (new location). MRI done early of Aug 2014 showed the lesion has grown to more than 2cm. Biopsy was done early of Sept 2014 and it's positive for MFH.

After getting advices from several specialists between surgery & cryoablation, we have decided to go for surgery next week.

In order to prevent any other recurrence in the future; we are now looking into all treatment options that are available for MFH patients.

1) Is/was there any immunotherapy trial done on any MFH patient(s)? If yes, is there anyway that I can get in touch with the person in charge of the trial to know more about the results?

2) Is there any plan to do immunotherapy clinical trial on MFH patients at this moment or in the near future; whether at your hospital or else where?

Note: MFH is also known as metastatic pleomorphic undifferentiated sarcoma.

Intan Mansor

Intan, thank you for reaching out. We passed your question on to MSK physician Sandra D’Angelo, who responds:

“I’m focusing my efforts in developing immunotherapies for patients with metastatic sarcoma. Unfortunately, there are no trials currently planned in the adjuvant setting to prevent recurrence since there is limited data available that it works so far.

I am planning a phase II study of ipilimumab and nivolumab (a PD1 inhibitor which has proven to be quite efficacious in melanoma) this study is sponsored through CTEP and will be conducted through the Alliance for Clinical Trials in Oncology Cooperative group. It is due to open up in about 4-6 months.”

I would like to know if you have any upcoming immunotherapy t cell trials for solid tumors in the lungs and breast cancer

I am a patient at Sloan with follicular B cell lymphoma that has trans mutated in large B cell lymphoma. I was treated with bendermustine and rituximab My cancer returned and my dr wants to treat me with rchops. I will not do it. When will the trials start on lymphoma and what will the criteria be?

Steve, there is an open trial at MSK using engineered T cells for which you might qualify. The lead investigator is Craig Sauter. You should speak with your MSK treating physician about what the criteria are for the trial. Thank you for your comment.

Hi there
I've been reading with interest about the immuno drugs that you are using especially nivolumab. I see that you are now trailing it on patients with advance oesophageal cancer. Have you seen any positive results with it or is it too early in the trail status.
Thank you for your time

Is there any immune therapy clinical trial being conducted at MSKCC, with specific focus on (PSMA/ CAR T-cell for prostate cancer)? Had been treated with harmon & chemo therapies, but it continues to metastasis to bone and PSA continues to rise.

Dear Basharat, we reached out to investigator Michel Sadelain for comment. He says, “We are in the process of seeking funding to support and then open a trial in prostate cancer. We anticipate opening this trial in 8-10 months. The PI will be Dr Susan Slovin.” Thanks so much for your question!

Thank you for your reply. I am well aware of the trail you mention. We are waiting to see if my father is a suitable canidate for it at the Royal Marsden, London, England. My father has been fighting for the past 8 mths and I have been fighting hard to get him on an immuno trail as I work in medical research here in the UK and believe this is the path to follow. His consultant has put up a fight to try and stop us telling me to stop looking for a miracle cure. Its makes me laugh, why would I be in the job I do today if I didnt think there could be a cure for cancer? Anyway I would like to say thank you for bringing a possibility even if its ever so small, to a cancer that has no other treatments apart from standard chemo. My dad may be able to outlive his prognosis with your help.

Hello. My 74 year old mother was diagnosed July 2015 with pancreatic cancer stage 4 which has metastasized to the liver.

She has gone through three different rounds of chemo and one radiation treatment. Her c19-9 tests initially were at approximately 33,000. Throughout treatment they dropped to approximately 1500. About a month ago they started to increase and are now at 3200.

At her meeting today with her oncologist she was told chemotherapy was no longer a viable option and there was nothing else that could be done. I would like to know what or if any immunotherapy trials are available or if there are any other treatments you suggest.

Thank you,
Mariana Durand Giesler
