February 4 is World Cancer Day, a time to mark international efforts to prevent, detect, and treat cancer. Immunotherapy, one of the most significant advances in treating cancer, was pioneered here at NIH more than 30 years ago. Today, IRP senior investigator Claudia M. Palena, Ph.D., is pushing cancer immunotherapy forward with the discovery of a novel target for cancer vaccines.

IRP’s Bruce Tromberg Elected to National Academy of Medicine

Advances in Bioengineering Drive Life-Saving Medicine

Dr. Bruce Tromberg

“To discover new things, you need new ways to see them,” says Bruce J. Tromberg, Ph.D., Director of the National Institute of Biomedical Imaging and Bioengineering (NIBIB). That’s why he has spent the past 30 years of his career improving and inventing tools to help doctors and scientists conduct cutting-edge biomedical research and apply their findings to the task of saving lives. This past October, Dr. Tromberg was elected to the National Academy of Medicine (NAM) for his contributions to the fields of biophotonics and biomedical optics, as well as his leadership in the biomedical engineering and imaging community.

Combination Therapy Shows Increased Effectiveness Against Brain Cancer

Additional Treatment Cuts off Tumor Cells’ Escape Route From Anti-Cancer Drug

Despite the many therapies that scientists have created to fight cancer, treating the disease is often still a frustrating game of cat and mouse. Just when doctors think they have managed to defeat their wily opponent, it comes roaring back as strong as ever. A new IRP study suggests a two-pronged approach that relies in part on an existing anti-cancer drug could more effectively thwart a particularly deadly form of brain cancer.

NIH Mourns the Passing of Ji Ming Wang

The IRP community is profoundly saddened by the recent passing of Ji Ming Wang, M.D., Ph.D., Senior Investigator and Head of the Chemoattractant Receptor and Signal Section in the Cancer Innovation Laboratory at NIH's National Cancer Institute (NCI). He died unexpectedly on December 24, 2022.

Dr. Wang studied the role of chemoattractant receptors in infection, inflammation, immune responses and cancer progression for over 30 years. In 1998, Ji Ming was the first to identify a critical role for the receptors in mediating cancer cell metastasis to distant organs. His later work focused on leukocyte infiltration, a hallmark of inflammation and cancer progression.

Predicting Risks and Benefits for Lung Cancer Screening

IRP Researchers Refine Tools to Maximize the Benefit from Life-Saving Tests

Eleven years ago, IRP senior investigator Hormuzd Katki, Ph.D., had a bit of an eureka moment during a press event announcing the results of the National Lung Cancer Screening Trial, which demonstrated that annual screenings cut the risks of dying from lung cancer in heavy smokers by 20 percent.

“It struck me as I read the trial results that not only was this a very important trial, but that it was possible that different people will have different benefits from lung cancer screening,” Dr. Katki remembers. “Even within this group of very high-risk smokers who were part of the trial, you can identify some people who get much more benefit than other people, and that has implications for who should be offered this kind of screening.”

Michael Gottesman Reflects on Tenure Leading Intramural Research Program

Renowned Cancer Scientist Stepped Down After 29 Years in Position

Dr. Michael Gottesman

Dr. Michael Gottesman has been a member of the NIH community since 1976. He has held many positions throughout his tenure, including spending 29 years as the Deputy Director of Intramural Research (DDIR). He stepped down as DDIR this past year and has returned to focusing solely on being Chief of the Lab of Cell Biology at the National Cancer Institute (NCI). Dr. Gottesman recently participated in an interview with the NIH Office of Technology Transfer, excerpts of which we are re-posting here on the "I Am Intramural" blog. 

Simple Blood Test May Thwart a Complicated Cancer

Signs of Past Viral Exposure Predict Liver Cancer Risk

The liver has a difficult but important job. It serves as the central processing plant for all the food, drinks, and drugs we take in, separating and breaking them down into usable nutrients and toxic wastes that need to be removed from the body. It’s no surprise, then, that diseases affecting the liver can have life-threatening consequences. In particular, infections like hepatitis B and C and liver damage caused by alcohol, drugs, or fatty liver disease can all lead to liver cancer. Unfortunately, even though the presence of these conditions are harbingers of possible liver cancer, the disease often passes unnoticed until it is at an advanced, less treatable stage.

IRP senior investigator Xin Wei Wang, Ph.D., and his NIH research team are developing ways to detect liver cancers much earlier, when existing treatments are much more likely to stop their growth. In honor of Liver Cancer Awareness Month this October, I talked to Dr. Wang about his research and the novel blood test his lab has developed to predict liver cancer risk.

A Year of Honors for IRP Cancer Researchers

Four NIH Scientists Received Prestigious Recognition in 2022

The complexities of cancer, which is actually a collection of many diseases, has made conquering it an enormous challenge. Fortunately, researchers in the NIH Intramural Research Program are up to the task. This year, four IRP investigators in NIH’s National Cancer Institute (NCI) have been recognized for their groundbreaking contributions to answering fundamental questions about the disease and the immune system’s response to similar threats.

Bringing Out the Big Guns Against Blood Cancer

IRP Research Shows Benefits of More Intensive Treatments for Certain Patients

Fate can be cruel, especially when it comes to a rare, highly fatal blood cancer called acute myeloid leukemia (AML). Even when months of intensive chemotherapy appear to cause a complete remission of the disease — meaning doctors cannot detect any remaining cancer cells in a patient’s body — roughly half of those patients see the cancer return within two years, or even as soon as six months. Sadly, most of them don’t survive their second bout with the disease.

As a medical student, IRP senior investigator Christopher Hourigan, M.D., D.Phil., thought this outcome was unfair. More than that, he thought it indicated that the standard ways doctors determined if an AML patient was in remission were inadequate, and that remission might not even be the right goal. That’s why he has focused his career on finding ways to detect, prevent, and treat AML recurrence, known in his field as ‘relapse’.

“I was a scientist before I became a doctor, and it was really eye-opening to me, when I started to practice medicine, how difficult some of the treatment decisions were and how limited the information available was to inform those decisions,” Dr. Hourigan says.

Teaming Up to Tackle Engineering Challenges

Innovation Awards Accelerate Development of New Research Techniques

Scientists spend years, even decades, intensely studying a specific disease or biological system, an approach that yields unrivaled knowledge. However, many important scientific questions require a deep understanding of several subjects. As a result, the IRP has numerous programs dedicated to encouraging scientists with different areas of expertise to work together.

One such program is the NIH Director’s Challenge Innovation Awards, which funds innovative, high-impact projects that require the cooperation of researchers in more than one of NIH’s Institutes and Centers. This year, the program selected six promising proposals with one foot in the disciplines of biology and medicine and another in engineering or the physical sciences.
