Tel Aviv University Nanoprobes Light Up Stray Cancer Cells

New Cancer Research Is Improving Cancer Treatment
New Cancer Research Is Improving Cancer Treatment

While cancer treatment often includes surgery, even a few missed cells can lead to recurrence and metastasis. Recent development of a “smart probe” that pinpoints cancer cells may greatly improve the effectiveness of surgical options.

Challenges of Surgery as Cancer Treatment

Removal of solid tumors can still leave behind stray cells that evade detection by MRI or CT. In some cases, surgeons end up damaging otherwise healthy tissue in an effort to excise all diseased cells.

Extensive studies by an interdisciplinary team at Tel Aviv University culminated in development of a nanoprobe that literally shines a light on cancer cells. When injected into a patient a few hours before surgery begins, the probe can alert the surgeon to the presence of cancer cells that might have been missed.

“Shedding a Light” on Cancer Cells

The probe is activated by the presence of an enzyme known as cysteine cathepsins, which occurs in higher numbers in tumor cells than in healthy cells. When the probe identifies cancerous cells, it triggers a fluorescent signal in those areas, while healthy tissue remains dark.

In tests conducted on mice with melanoma and breast cancer, the survival rate of mice that underwent probe-assisted surgery was double that of the mice who received regular surgery. Now that the team has registered patents for the technology, the next step is to start clinical trials with hopes of commercially marketing the probe.

Lymph Node Metastasis Uses Blood Vessel Pathways to Spread Cancer

Lymph node metastasis can have major implications for immuno oncology treatment. In a recent study, scientists examined the progression of metastatic tumor cells to learn more about how they are disseminated throughout the body.

Is Treatment of Lymph Node Metastases a Priority?

When cancer metastasizes in the lymph nodes, it’s generally a sign of an exceptionally aggressive tumor and a poor prognosis. Scientists differ on the treatment of lymph node metastases, with some experts believing it’s “clinically inconsequential” while others think they should be treated promptly to prevent distant metastases.

Results of clinical testing further complicate the issue. In one trial, removal of anything beyond the first lymph node had no benefit for patients who had received radiation and systemic therapies, while in another, lymph node treatment was found to help a subgroup of patients with breast cancer.

Tracing the Journey of Metastatic Cancer Cells

A team of researchers implanted a group of mice with cancer cells that expressed a photoconvertible protein known as Dendra2. This feature allowed scientists to photoactivate selected metastatic cells in the lymph nodes and follow their path.

Originally, metastatic cells were thought to travel by either blood vessels or the lymphatic system. In studying the affected mice, scientists determined that the metastatic cells followed a hybrid route by invading blood vessels within a lymph node, using it as a means of exit by which the cells could travel to the lungs and other organs.

Tips for Coping with a New Cancer Diagnosis

Do you Have or Know Someone Who is Currently Experiencing a Hard to Treat Cancer? There is Hope!
Do you Have or Know Someone Who is Currently Experiencing a Hard to Treat Cancer? There is Hope!

When you receive a diagnosis of cancer, your mental and emotional adjustment can make a difference during your course of immuno oncology treatment. Unfortunately, most people have no frame of reference for coping with such news.

The American Cancer Society offers helpful tips for coming to terms with a cancer diagnosis and continuing to live life to the fullest.

Follow Your Own Path

Your situation is unique. Others may offer ideas of what has worked for them, but don’t feel obligated to follow them to the letter. View these tips as suggestions and try out different methods to find your own best solution.

Learn About Your Cancer

Knowledge is power. The unknown is often more frightening than the reality, so take time to educate yourself about your type of cancer and the various treatment options that are available.

Stay Active

The link between exercise and mood is well-documented. Physical activity stimulates production of endorphins, which are natural mood elevators. Consult with your doctor to make sure you’re not overdoing it.

Let Your Feelings Out

Many people believe that fear, anger and other negative emotions must remain hidden, but that can make your situation even harder to bear. Talk to friends and family, join a support group or try an artistic outlet such as writing or painting.

Be Kind to Yourself

Make a point each day of doing something that makes you happy, whether it’s meeting a friend for lunch or simply meditating for 15 minutes.

Immunotherapy and Gastric Cancers – What to Know

Immunotherapy and Gastric Cancers
Immunotherapy and Gastric Cancers

Immunotherapy and other targeted methods have shown promise in effectively fighting gastric and gastroesophageal junction (GSJ) cancers. At a recent summit meeting, Dr. Andrew Ko, professor of medicine at the University of California, San Francisco, discussed cancer treatment for gastric and GSJ cancers as well as current challenges.

Checkpoint Inhibitors and Gastric Cancers

In terms of recent developments, Ko pointed to last year’s FDA approval of pembrolizumab as a turning point in the treatment of advanced cancers. Pembrolizumab (trade name Keytruda) is a checkpoint inhibitor used on cancers with positive expression of PD-L1, a protein that enables cancer cells to avoid attack by the immune system.

Ko also mentioned nivolumab (trade name Opdivo), another checkpoint inhibitor. Nivolumab is used for melanoma and lung cancers, but clinical trials have shown that it has potential as a secondary treatment following chemo-radiation and surgery for patients with certain GEJ cancers.

Unfortunately, cases of upper gastrointestinal cancers continue to rise in Western countries. Ko explained that, despite improvements in immunotherapy cancer treatment, many patients are still non-responders, creating continued urgency in finding additional methods.

The Future of Gastric Cancer Treatment

According to Ko, immunotherapy still holds the greatest interest for cancer researchers.

– Studies are exploring combinations of drugs, such as nivolumab plus ipilimumab (trade name Yervoy).

– Other studies are focused on moving targeted agents from secondary to first-line treatments.

No two cases of cancer are the same, so scientists are finding that cookie-cutter cancer treatment is not always the best solution. According to a recently published study, a personalized vaccine has shown promise for boosting ovarian cancer survival rates.

Ovarian Cancer: The “Silent Killer”

An international team of researchers conducted the study of ovarian cancer, often referred to as a “silent killer” because it’s usually in an advanced stage by the time of diagnosis. Chemotherapy plus surgery is the conventional course of treatment, but team member Dr. Lana Kandalaft notes that 85 percent of patients experience recurrence.

Matching Cancer Treatment to Patient

Immunotherapy is a form of treatment that uses a patient’s own immune system to attack and kill cancer cells. In this case, researchers created a vaccine by harvesting a patient’s immune cells, then exposed them to cells from the tumor so they could be identified.

All patients in the study were treated with a combination of immunotherapy drugs, while a certain number also received the vaccine. After one year, the vaccinated group had a survival rate of 100 percent compared to 60 percent of the control group.

Results continued to be encouraging after two years. The vaccinated group showed a survival rate of 78 percent, while the rate dropped to 44 percent with patients receiving drugs alone.

Bone Cancer or Sarcoma is in the focus in July

What are the types of bone cancer? Can it be treated with immunotherapy for cancer programs? July is Bone Cancer Awareness Month, making it a good time to share some facts about the disease from the National Cancer Institute.

Basics of Bone Cancer

As the name implies, bone cancer is a malignant tumor that forms in bone tissue. The majority of bone tumors are benign, which means they’re non-fatal and don’t spread.

On the other hand, bone cancer CAN spread to other parts of the body. Regardless of the location of the metastasis, or spread, the disease is still referred to as bone cancer based on its original site.

Types of Bone Cancer

– Osteosarcoma, usually found in the knee or upper arm, develops in hard bone tissue.

– Chondrosarcoma forms in cartilage, which is the tough but resilient tissue that cushions joints.

– The Ewing Sarcoma Family of Tumors, or ESFTs, are thought to arise from primitive nerve tissue in bone or soft tissues.

Bone Cancer Symptoms

Chronic pain or swelling in or near a bone are the most common symptoms of bone cancer, but they could also be indicative of other conditions, so it’s important to be tested.

Treatments for Bone Cancer

Traditional treatments such as surgery and chemotherapy are often used with bone cancer patients. The NCI and other organizations also sponsor frequent clinical trials to investigate immunotherapy for cancer treatments.
