Study Found Proteins in Urine Can Indicate Pancreatic Cancer 

According to a recent study, published in Clinical Cancer Research, a journal of the American Association for Cancer Research, researchers have found three proteins in urine that indicate early stage pancreatic cancer. 

For the study, researchers analyzed 488 urine samples, including 192 from patients with pancreatic cancer, 92 from patients with chronic pancreatitis, and 87 from healthy people.  In addition, they looked at 117 urine samples from patients with diseases of the liver and gall bladder.  Of the 1,500 proteins found in the urine samples, the research team focused on three: LYVE1, REG1A and TFF1.  The researchers found that patients with pancreatic cancer had elevated levels of all three proteins compared with healthy patients and patients with pancreatitis.  Using all three proteins, they were able to detect early stage pancreatic cancer more than 90 percent of the time. 

“For a cancer with no early stage symptoms, it’s a huge challenge to diagnose pancreatic cancer sooner, but if we can, then we can make a big difference to survival rates,” said Nick Lemoine, Director of Barts Cancer Institute at Queen Mary University in London.  “With pancreatic cancer, patients are usually diagnosed when the cancer is already at a terminal stage, but if diagnosed at stage 2, the survival rate is 20 percent, and at stage 1, the survival rate for patients with very small tumors can increase up to 60 percent.”

According to the Pancreatic Cancer Action Network, a nationwide network of people dedicated to working together to advance research, support patients and create hope for those affected by pancreatic cancer, pancreatic cancer has the highest mortality rate of all major cancers.  It is also one of the few cancers for which survival has not improved substantially over nearly 40 years. 

Pancreatic cancer is difficult to diagnose because patients usually don’t display symptoms until the cancer has progressed and spread to other parts of the body.  Common early symptoms include loss of appetite, mild weight loss and mild discomfort in the upper abdomen or occasionally in the middle-back.  Because these symptoms can be attributed to any number of conditions, early signs are often ignored or missed. 

Treatment for pancreatic cancer can be a curative or palliative approach involving surgery, radiation therapy, chemotherapy, stereotactic radiosurgery or a combination.  Due to side effects and complications associated with surgery for pancreatic cancer patients, stereotactic radiosurgery can be a safe, noninvasive option. 


When Cancer Comes Back 

My cancer came back. Four words that no one ever wants to say, or hear a loved one say. 

They fought the battle once and now their cancer is back and in a new location in their body. 

Metastatic cancer is a cancer that has spread from the place where it first started, to another place in the body. A tumor formed by metastatic cancer cells is called a metastatic tumor or a metastasis, and the process by which cancer cells spread to other parts of the body is also called metastasis. Metastatic cancer has the same name and the same type of cancer cells as the original, or primary, cancer. For example, breast cancer that spreads to the lung and forms a metastatic tumor is metastatic breast cancer, not lung cancer.

The most common sites of cancer metastases are the bone, liver, and lung. Although most cancers have the ability to spread to many different parts of the body, they usually spread to one site more often than others. The plan for treatment will depend on the type of primary cancer; the size, location, and number of metastatic tumors; age and general health; and previous treatments.


Patient Education: Cancer Recurrence Common Terms and What They Mean 

Once treatment is completed, many cancer survivors find they have still have issues and concerns that they did not expect. The one people fear the most is the news that the cancer has come back. Patients coping with a second cancer diagnosis may hear unfamiliar medical terms related to their disease and its treatment. We’ve highlighted some common cancer terms below and provided brief overviews of what each term means.

Cancer Recurrence: The return of cancer after treatment and after a period of time during which the cancer cannot be detected. These cancer cells may have been dormant for a period of time, but eventually they continued to multiply, resulting in the reappearance of the cancer. The same cancer may come back where it first started or somewhere else in the body.

Localized Recurrent Cancer: Cancer that has recurred at or near the same place as the original tumor, usually after a period of time during which the cancer could not be detected.

Metastatic Cancer: Metastatic cancer is cancer that has spread from the place where it first started to another place in the body. Cancer cells can travel through the lymph system to other organs or in the bloodstream to other parts of the body. Metastatic cancer has the same name and the same type of cancer cells as the original, or primary, cancer. For example, breast cancer that spreads to the lung and forms a metastatic tumor is metastatic breast cancer, not lung cancer.

Metastasis: The process by which cancer cells spread to other parts of the body. 

Metastatic Tumor: A tumor formed by metastatic cancer cells.

According to the American Lung Association, lung cancer is the leading cancer killer in both men and women in the United States and causes more deaths than colorectal, breast and prostate cancers combined.  An estimated 158,040 Americans are expected to die from lung cancer in 2015, accounting for approximately 27 percent of all cancer deaths.  

Lung cancer is the uncontrolled growth of abnormal cells in one or both lungs.  These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue.  As they grow, the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood.
