The Importance of Gut Bacteria in the Spread of Pancreatic Cancer

Gut bacteria, or microbiome, include organisms that manufacture vitamins and promote healthy digestion and other functions. A study recently published in Cancer Discovery found that pathogenic gut bacteria can have a negative impact on pancreatic cancer treatment.

When Gut Bacteria Fights the Immune System

A research team at NYU School of Medicine conducted tests on both mice and humans with pancreatic ductal adenocarcinoma (PDA), a particularly aggressive form of pancreatic cancer. The scientists discovered that pathogenic, or “bad,” gut bacteria migrated to the pancreas, increasing bacterial presence by a thousand times.

Problems arise when this unbalanced mix of bacteria triggers a shutdown of immune cells, allowing cancer cells to multiply unchecked. Checkpoint inhibitors are a type of immunotherapy cancer treatment that reactivates immune cells, but they’re ineffective against the overwhelming amount of bacteria in the pancreas.

Using Antibiotics to Supplement Immunotherapy

When the researchers treated the mice with antibiotics, the amount of bacteria decreased enough to “flip the switch” on immune cells, thereby slowing cancer growth. In addition, checkpoint inhibitors were approximately three times more effective when used in conjunction with antibiotics.

Checkpoint inhibitors had previously failed to treat pancreatic cancer in clinical trials, so scientists are encouraged by these results. The team is now recruiting PDA patients to test the antibiotic-checkpoint inhibitor combo.

New Research: Programming DNA to Deliver Targeted Cancer Treatment

DNA carries the genetic information that makes you who you are. While DNA directs protein production by cells, scientists have discovered a way to turn DNA into an on/off switch for applications in cancer treatment.

DNA: A Protein Computer

In essence, DNA operates like a computer. Just as all digital data relies on various configurations of a two-component code, DNA uses different arrangements of a four-component code to determine which proteins need to be manufactured.

This similarity has given rise to a field called DNA computing. A research team at the University of Delaware recently engineered DNA strands with a code to create circuits programmed to open and close based on a specific logic.

Leveraging DNA Code

The next step was to make and purify the proteins that the scientists wanted to use. Once the custom-made DNA strands were received from the manufacturer, the proteins were attached to form protein-DNA conjugates.

When the DNA circuits were tested on both E. coli bacteria and human cells, the target proteins went through a series of stages just as they had been programmed to do.

Applications for Cancer Treatment

Once the DNA circuits proved to be successful, the UD team tested them with cancer prodrugs, which are inert until they’re metabolized into therapeutic form. The scientist designed DNA circuits to control the protein that triggers metabolism of the prodrug. Professor Wilfred Chen, lead author of the study, anticipates a future of “plug-and-play” DNA circuits.

What if you could determine your need for bladder cancer treatment from a routine urine sample, just like many other medical conditions? Scientists have recently developed a test that could make this a reality.

Using Gene-Based Testing for Early Cancer Detection

A team of researchers at Johns Hopkins Kimmel Cancer Center has been studying cancer genes to find more effective methods of early detection. Earlier this year, they announced a new blood test called CancerSEEK, which screens for eight different types of cancer, and PapSEEK, which screens for endometrial and ovarian cancers via cervical fluid samples.

In a study published in March, the team revealed the addition of another test called UroSEEK. Urine samples are analyzed for the presence of gene mutations or abnormal numbers of chromosomes, both of which are associated with bladder cancer and upper tract urothelial cancer (UTUC).

Identifying New Cancer Cases and Recurrences

During clinical studies involving 570 at-risk patients, UroSEEK had an 83 percent success rate identifying those who did develop bladder cancer. When UroSEEK was used in conjunction with cytology, the standard test for bladder cancer, accuracy rose to 95 percent.

According to Dr. David McConkey of the Johns Hopkins Greenburg Bladder Cancer Institute, bladder cancer has a high rate of recurrence. Another benefit of UroSEEK is that it can be used to effectively monitor patients who have already undergone treatment for bladder cancer.

Individually Created Cancer Treatment for Each Patient

Not so long ago, a diagnosis of cancer was the worst news a patient could hear. Flash forward to today when, thanks to remarkable improvements in cancer treatment, patients are learning to live with the disease as their “new normal.”

Liz Burke: One Woman’s Story

In TheJournal.ie, an Irish news website, a woman named Liz Burke shared her experiences in honor of Daffodil Day, a fundraiser for the Irish Cancer Society. Liz was originally diagnosed with breast cancer in 2007.

After a lumpectomy, Liz underwent a course of chemotherapy followed by another of radiotherapy. She demonstrated her sense of humor by relating a story about purchasing a wig to cover her baldness and finding it one day in the mouth of her Jack Russell terrier.

Two years later, Liz’s doctor discovered that breast cancer cells had metastasized to her liver. This triggered another nine months of chemotherapy followed by two years of maintenance, but the good news is that the tumors became inactive.

Finally, one more blow. After five years, the breast cancer metastasized again, this time resulting in a brain tumor. Liz had surgery to remove the tumor and radiotherapy treatment afterwards.

“People Survive Cancer”

These days Liz follows a regular schedule of MRIs, CT scans and weekly infusions. Her message? “People can live quite happily alongside cancer.” Liz believes we’re lucky to live in a time when so much progress is being made with new and effective cancer treatment.

Robots May Soon be Performing Lung Laparoscopies for Cancer Detection

Robots are becoming increasingly entrenched in manufacturing, but do they have a place in cancer treatment? Earlier this year, the FDA approved a new robotic device for use in diagnosing lung cancer.

Robotics: Building Better Surgical Devices

As a surgical resident in the early 1908s, Fred Moll became convinced that there was a better way to perform procedures. After resigning his residency, Moll went to work creating high-tech medical devices.

Today Moll has become known for his invention of the $2 million da Vinci Surgical System, which is the top-selling surgical robot used in laparoscopic procedures. Surgeons operate the device using electronic hand controls and a video monitor.

But Moll is not content to rest on his laurels. He’s certain that medical robots will eventually be able to work autonomously, without relying on a surgeon’s control.

The Future of Robotic Surgery

On March 22, the FDA approved use of the Monarch Platform, which is the first step toward Moll’s ultimate vision. The new system includes a pair of arms as well as a long tube for doctors to steer a camera and other instruments inside the patient’s body.

At this point, FDA approval covers the Monarch Platform for use by a doctor to diagnose (and eventually treat) lung cancer. According to Moll, the Monarch will be able to drive itself in as few as 18 months from now.

Protein Biomarker Found for Liver Cancer That May Allow for Early Treatment

While some cancer rates have dropped, cases of liver cancer have actually tripled since the 1980s, with only 20 percent of patients surviving more than five years after diagnosis. Scientists are hoping to fight this trend with the discovery of a new protein biomarker that can lead to earlier cancer immunotherapy.

Dire Prognosis for Liver Cancer

The grim mortality rate for liver cancer is largely due to the fact that it’s usually diagnosed in late stages, by which point the liver has already sustained too much damage. A study recently published in the journal Nature describes findings that may enable earlier diagnosis.

Using Tumor Suppressors for More Accurate Diagnosis

Anti-cancer proteins known as tumor suppressors have the ability to check the rapid cell growth. Problems arise when the tumor suppressors in cancer cells fail to do their job.

A team at the University of Basel in Switzerland went in search of more effective tumor suppressors by testing a mouse model of liver cancer. The researchers examined more than 4,000 individual proteins in the diseased tissue and compared them to those in healthy tissue.

One protein called histidine phosphatase (LHPP) was found in healthy tissue but not in the tumor cells. Similar results were found when the team focused on LHPP in humans with liver cancer. Scientists are hopeful that LHPP can serve as a biomarker, allowing for earlier diagnosis and treatment.
