Nano Drills Destroy Cancer Cells

By Jay Goth

Researchers have long sought alternative treatments capable of killing cancer cells while leaving healthy cells alone. Now, a team of scientists from Rice, Durham, and North Carolina State Universities may have uncovered one: A new innovation uses light to activate microscopic “nanomachines” that can drill into individual cancer cells.

In one test, it took just 60 seconds for a nanomachine to pierce the outer shell of a prostate cancer cell with dozens of tiny holes; overall, it took 1-3 minutes to destroy the cell by necrosis.

“Once developed, this approach could provide a potential step change in non-invasive cancer treatment and greatly improve survival rates and patient welfare globally.”

– Dr. Robert Pal of Durham University

Surfing with DAVE

By Jay Goth

The growth in cancer genomics has been one of the most exciting scientific and technological developments in cancer research, spurring significant advances in patient care and laying the groundwork for many future advances.

In the year since it was launched, the National Cancer Institute’s Genomic Data Commons (GDC) has collected and harmonized a vast quantity of cancer genomics data—more than 4.5 petabytes—which has been fundamental in the recent progress against cancer and holds the promise for continued improvement in our ability to diagnose, treat, and care for patients.

Now, as a data-analysis system, the GDC is taking major steps toward engaging the broader research community and encouraging further collaboration and data sharing. They recently introduced a new program – Data Analysis, Visualization, and Exploration Tools, an online, open-access cancer research resource called DAVE.

DAVE is a new web interface for exploring and analyzing cancer genomic data, in real time, online, without the need to download or process the data.

DAVE provides an unprecedented level of flexibility in exploring the data. Researchers can create custom cohorts for analysis by selecting patients with particular altered genes or other relevant biological and clinical features. And researchers are no longer bound to analyzing patients only in the context of their original project cohorts—a powerful innovation given the recent evidence that a tumor’s molecular features are far more accurate and informative for cancer subtyping than tissue of origin or histology.

Another step forward for precision medicine! For the details, visit the National Cancer Institute.

Finding the Source of Cancers

By Jay Goth

Investigators at the University of California San Diego School of Medicine and at Xijing Hospital and Sun Yat-sen Cancer Center in China say that DNA methylation can provide effective markers for at least four major cancers.

The biomarkers are able to differentiate malignant tissues from normal tissues and also provide information on prognosis and survival, according to the researchers.

“This new simple method will be of great value to pinpoint the primary source of the tumor.”

–Michael Karin, Ph.D., Professor of Pharmacology, UC San Diego School of Medicine.

“Choosing the proper cancer treatment with the best chance of recovery and survival depends greatly upon accurately diagnosing the specific type or subtype of cancer,” said Kang Zhang, M.D., Ph.D., founding director of the Institute for Genomic Medicine and co-director of biomaterials and tissue engineering at the Institute of Engineering in Medicine, both at UC San Diego School of Medicine.

Breakthrough FDA Ruling

By Jay Goth

The Food and Drug Administration (FDA) granted accelerated approval to the immunotherapy pembrolizumab for patients with solid tumors that have one of two specific genetic features known as mismatch repair deficiency and high microsatellite instability. The approval covers adult and pediatric patients whose cancer has progressed despite prior treatment and who have no alternative treatment options.

This is the first time that FDA has approved a cancer treatment based solely on the presence of a genetic feature in a tumor, rather than the patient’s cancer type.

“I think this is a step forward for precision medicine.”

–James Gulley, M.D., Ph.D., head of the immunotherapy section of NCI’s Center for Cancer Research

Having a biomarker to identify patients who are most likely to respond is “an area we have widely anticipated as being the next step in understanding how to better use immunotherapies,” said Dr. Gulley. “It’s a welcome first step, and there’s much more yet to be done.”

Key to Metastasis?

By Jay Goth

A team at Johns Hopkins has discovered the biochemical mechanism that tells cancer cells to break off from the primary tumor and spread throughout the body, a process called metastasis. Some 90 percent of cancer deaths are caused when cancer metastasizes.

“…what we came up with through our studies was this drug cocktail that could potentially inhibit the spread of cancer.”

— Hasini Jayatilaka, post-doctoral fellow at Johns Hopkins

Typically, cancer research and treatment has focused on shrinking the primary tumor through chemotherapy or other methods. But, the team said, by attacking the deadly process of metastasis, more patients could survive.

Finding Brain Cancer 5 Years Early

New research from academia


Interactions among proteins that relay information from one immune cell to another are weakened in the blood of brain cancer patients within five years before the cancer is diagnosed, said lead researcher Judith Schwartzbaum of The Ohio State University.

“this research could pave the way for techniques to identify brain cancer earlier and allow for more-effective treatment”

The Cancer Ecosystem

By Jay Goth

Cancer is increasingly being viewed as an ecosystem, a community in which tumor cells cooperate with other tumor cells and host cells in their microenvironment. As conditions change, the ecosystem evolves and adapts to ensure the survival and growth of cancer.

Successful treatment and prevention of cancer require an ecosystem, too—a coordinated unit of researchers, patients, health care professionals, health care systems, regulatory agencies, government, and industry. How can these partners work together as one interconnected community?

Sandra J. Horning, the Chief Medical Officer and Global Head of Product Development at Genentech and Roche has some ideas. Check them out here.

“Importantly, basic scientific research that unlocks the mysteries of cancer and discovers targets for therapy, early detection, and prevention is the core of a healthy ecosystem to tame the disease.”

GRAIL Raises $900M to Develop Early Blood Tests for Cancer

By Jay Goth

GRAIL is combining what it calls high-intensity (ultrabroad and ultradeep) sequencing and population-based clinical trials to characterize circulating tumor DNA (ctDNA) in healthy individuals and cancer patients. The ultimate aim is to develop cancer diagnostics that can detect tumors early enough to cure the disease. See the full story at Genetic Engineering and Biotechnology News.

New Article in GEN


This is a core focus for all precision medicine oncology approaches, including ours. We believe that a multi-omic focus that goes beyond circulating tumor cells can have major advantages.

The Importance of microRNAs

By Jay Goth

New Article in GEN Explores miRNA

After advances to genomics and transcriptomics technology, scientists have realized that about 98% of the genome contains sequences that perform key regulatory functions. Some of these sequences give rise to microRNAs (miRNAs), small noncoding RNA molecules that have emerged as one of the most complex, multilayered, and intriguing constituents of gene-regulatory networks.

“The future is bright for the diagnostic use of microRNAs”

– Christos Argyropoulos, M.D., Ph.D.

“The goal in biomarker development is to use microRNA expression-based biomarkers to better manage the clinical treatment of cancer,” declares Dr. Jingfang Ju,Ph.D., professor of pathology at the State University of New York at Stony Brook. Historically, mRNA expression, DNA mutations, and proteins have been used as the most common biomarkers.

Expanding the biomarker universe to create new diagnostic and treatment solutions is critical to improving the human condition and a main focus of Forentis Fund. To read the whole article in GEN, click here.

CAR-T Advances in Cancer Fight

By Jay Goth

Doctors in London say they have cured two babies of leukemia in the world’s first attempt to treat cancer with genetically engineered immune cells from a donor.

Treatments using engineered T-cells, commonly known as CAR-T, are new and not yet sold commercially. But they have shown stunning success against blood cancers. In studies so far by Novartis and Juno, about half of patients are permanently cured after receiving altered versions of their own blood cells.
