Cancer immunology research · Cancer wasting (cachexia)

Lingbing Zhang, PhD

Helping patients who have been told there is nothing more to be done — because for many of them, there is still hope.

Dr. Zhang studies a simple but overlooked idea. In advanced cancer, the tumor is not the only danger. The tumor can also break down the immune system — the body's defense system. He calls this breakdown tumor-induced immune disorder. His greatest contribution is the discovery that the disordered immune system does not just stop protecting the body — it directly harms it. The most visible sign of that harm is cachexia, along with the multi-organ damage commonly seen in patients with advanced cancer. The body loses muscle and fat together, and eating more cannot fix it. His work aims to repair the immune system at the root. For years, he has also shared what he learns directly with patients and families who are looking for answers.

“A patient can die while the tumor is not progressing.”

This line sits at the center of his work. A shrinking tumor is not the only sign of success. What also matters is whether the patient is getting stronger — eating, walking, and able to keep receiving treatment.

Why advanced cancer makes the whole body fail

This is how Dr. Zhang sees advanced cancer, in plain words. It is the idea behind his research, his book, and the medicines he is working on.

Point 1 · Advanced cancer

The tumor is not the only problem

Patients do not die only because a tumor grows. The tumor also breaks down the immune system — the body's defense system — and turns it against the body it should protect. Dr. Zhang calls this breakdown tumor-induced immune disorder.

“A scan describes the tumor. It does not necessarily describe the condition of the person carrying it.” Once the defense system fails, it becomes a force that destroys the body — and cachexia, organ failure, and other consequences follow. Treatment also becomes harder to bear.

Point 2 · Cachexia

Cachexia is not starvation

Cachexia (pronounced ka-KEK-see-a) is the severe wasting seen in many people with advanced cancer. It is not simply eating too little, and it is not a lack of effort or willpower.

The disordered immune system sends signals that break down the body's fat and muscle from the inside. He puts it this way: “Cancer cachexia, in essence, is an immunological syndrome manifested as a metabolic one.” In plain words: the wasting looks like a body-fuel problem, but the root is the immune system. That is why food alone — and medicines that only boost appetite — cannot reverse it, and why “just eat more” is not the answer families are usually given.

Point 3 · Treatment

Broken defenses can make good treatment stop working

Chemotherapy (drug treatment that kills cancer cells) and immunotherapy (treatment that helps the immune system fight cancer) both depend on a working immune system. Checkpoint inhibitors — drugs that release the brakes on immune cells — are no exception.

When the immune system is broken, even a good treatment may stop working. Repairing the disorder may open the door to treatment again.

Point 4 · New medicines

One target is not enough

This disorder affects the whole body. Many harmful signals act at the same time. Blocking just one molecule (one small target in the body) is usually not enough.

That is why single-target drugs keep failing. The real fix must restore balance to the immune system — upstream, at the source — not chase one signal at a time downstream.

So care has two jobs, not one

Control the cancer — and protect the systems that keep the patient alive and able to bear treatment. That means watching weight, muscle, strength, inflammation, and new complications — not just the scans.

“Every life lost to immune dysfunction is one we might have saved.”

01 · Patients first

For patients who were told to stop hoping

Many patients who find Dr. Zhang have been told that nothing more can be done. He believes many of them still have a chance. Over the years, some patients and families took his research-based ideas to their own doctors, and their problems were resolved; later, they shared their stories with permission. Two stories are told here — including one that did not end the way everyone hoped.

Patient story · Shared with permission

“Learning to live instead of waiting to die”

Mindy — stage IV breast cancer that has spread to other parts of the body

For Mindy, one of the hardest parts of stage IV breast cancer was constant joint and foot pain. Some days, just standing up or walking across a room was too much. Pain medicines dulled the pain, but they left her sleepy and cut off from her family. She began to prepare for the idea that she might not have much time left.

Looking for answers, she reached Dr. Zhang through X. He shared what his research had taught him and suggested an approach she could discuss with her cancer doctors. She took the ideas to her own team. Together, they decided what was right for her. Over time, the severe pain that had ruled her days eased a great deal — and she could focus on living, not just getting through the day.

Five years on, she treasures time with her family. She sews, quilts, and paints — and she hikes in Yosemite National Park. A line she added to her X profile sums up the change: “Learning to live instead of waiting to die.”

“Most importantly, keep living.”

Lee: the turnaround — and the loss

Written by Tracey, about her husband Lee — stage IV kidney cancer

When Lee's cancer became advanced, his wife Tracey watched cachexia — severe loss of weight, muscle, and strength — take hold day by day. His body seemed to disappear before her eyes, even with all the care he was getting. They had two young children who needed their father, so she refused to stop searching. Late-night reading in patient communities led her to Dr. Zhang's work on cachexia and the immune-system problems behind it.

Lee's doctor approved an approach based on those ideas. Within five days, Lee had gained two pounds. Over the next weeks he regained weight and strength, and began enjoying life again. Stronger, he was able to restart immunotherapy (treatment that helps the immune system fight cancer). His tumor responded. His scans improved. Real improvement began to feel possible.

“He is gaining weight. I am so thankful. It is nice to see his muscles returning! I didn't think it was ever possible.”

— Tracey, during Lee's recovery

Then, just as recovery seemed within reach, Lee developed a pericardial effusion — fluid building up around the heart. In Tracey's account, the problem was not found and treated as fast as it needed to be. By the time emergency steps were taken, it was too late. Lee died — not, as Tracey writes, because the cancer took him, but because a treatable problem was caught too late.

She is still grateful for what the turnaround gave them: real extra time, strength regained, and precious family memories. She asked for their story to be shared so other families keep searching.

“Do not stop searching for answers… Hope matters.”

— Tracey, closing her account of Lee's story

“You have information that oncologists don't yet have. I think all you can do is help those who want your help. I can tell you have a big heart.”

— a patient

“I'm so inspired by your obsession. The way you are constantly trying to solve things. It's so heartening for us… to know there are dedicated people out there solving real problems keeps my hope alive.”

— a patient

“You have a huge heart. I sense that. You should have been a clinical oncologist!”

— a patient

“Congratulations on your brilliant work. You have my full trust and admiration! I have no doubt you will succeed fully.”

— Gail

“Your mission moves me.”

02 · Talks

Speaking: from TEDx to the AACR

Dr. Zhang explains his idea — that the tumor breaks down the immune system — to public audiences and to cancer researchers alike.

TEDxCapeMay, 2019 — “A New Life-Saving Approach to Cancer Treatment.” In this talk, he argues that treating the immune disorder behind cachexia — not only the tumor — could prevent a large share of cancer deaths. In the talk, he puts that share at 30% or more. He is listed on the TEDxCapeMay 2019 speakers page.

Research papers & opinion

One idea runs through twenty years of work: how well treatment works depends on the state of the patient's immune system. When the tumor damages that system, the patient wastes away.

Research & reviews

Commentary & opinion

  • Targeting the Upstream Driver of Cancer Cachexia

    Journal of Clinical Trials and Case Studies · 2026 — Zhang L, Norton JA

    Commentary. The body's inflammatory signals back each other up, so blocking one at a time cannot work. Treatment should aim upstream — at the source — and restore balance to the immune system, early.

  • The Emperor's New Clothes? Rethinking Modern Cancer Care

    Digital Journal of Science · 2026 — Zhang L · DOI: 10.63592/DJS/172

    His argument for a wider view of care. Modern cancer care focuses too much on the tumor. But “a patient can die while the tumor is not progressing.” So, alongside the scans, care must watch weight, muscle, strength, inflammation, and new complications.

  • Immunology of Cancer Cachexia

    Archives of Clinical and Biomedical Research · 2025 — Zhang L

    Editorial: “Cancer cachexia, in essence, is an immunological syndrome manifested as a metabolic one.” In plain words: the wasting looks like a body-fuel problem, but its root is a disordered immune system.

  • A New Frontier in Cancer Treatment: Addressing Self-destroying Immune Dysfunction

    Archives of Clinical and Biomedical Research · 2025 — Zhang L

    Editorial. “Cancer doesn't kill by tumor alone. It hijacks our immune system, turning it against us.” It also explains why checkpoint inhibitors (drugs that release the brakes on immune cells) cannot work when the immune system itself is broken.

  • Treating Cancer Cachexia Should be Essential in Cancer Care

    Archives of Clinical and Biomedical Research · 2025 — Zhang L, Bonomi PD

    Treating cachexia should be a core part of cancer care, not an extra. Care should look for it early and treat the root cause — the immune disorder — not only ease symptoms.

Cover of 'When the Body Turns Against Itself: A Patient's Guide to Cancer Cachexia' — a lone figure walking through darkness toward the light

When the Body Turns Against Itself

A Patient's Guide to Cancer Cachexia · 2026

For years, Dr. Zhang wanted to write a book for patients, because so few people understand what cachexia is or why it happens. This guide uses plain language. It is the first book on cachexia written for patients and families, not for doctors. It explains why a person with cancer loses weight and muscle even when they eat, why willpower and food alone cannot stop it, and what families can do today.

The lone figure on the cover is the author himself: a researcher searching for the truth about cancer cachexia, walking alone in darkness toward the light.

05 · New drugs

New drugs in development

Building the treatments his research points to.

R-ketorolac — lead drug candidate

A drug candidate aimed at the immune disorder

R-ketorolac is one form (the “R” form) of a known drug, ketorolac. It is being developed to calm and rebalance the immune system — not simply to reduce inflammation. In a peer-reviewed mouse study (J Cachexia Sarcopenia Muscle, 2024), it reversed cancer cachexia in mice: it protected weight, muscle, and fat, lowered IL-6, and restored T cells. Survival in mice with tumors rose from 10% to 100%. These are animal results. Whether they hold in patients is what development is now testing.

Investigator-led Cedars-Sinai KetoROCX trial (NCT05336266) has completed its primary treatment phase; per the ASCO 2025 abstract, most patients showed weight-loss reversal and increased daily activity.

Investigational — not an approved treatment. R-ketorolac is still in development. It has not been proven safe or effective in humans, and it is not available as a treatment outside of research.
