November is Pancreatic Cancer Awareness Month and today, November 22, is "Purple With a Purpose" day. I am wearing my purple ribbon today for my mom who died of pancreatic cancer in 1987 at the age of 68.
This information about pancreatic cancer is from the WebMD.com site:
Pancreatic cancer is one of the most lethal tumor types because it's too often diagnosed in a later, advanced stage. But a new study suggests that a simple blood test might help spot the disease earlier.
The study is described as small and preliminary, and investigators cautioned that the initial findings will need to be confirmed in larger trials.
"Pancreas cancer is the fourth leading cause of cancer death in the United States," said study coauthor Dr. Nita Ahuja, an associate professor of surgery in the department of oncology and urology at the Johns Hopkins University School of Medicine, in Baltimore. "There have been minimal to no improvements in the survival from this disease in the last 40 years. There are over 40,000 people diagnosed every year and about that many deaths."
"One of the main reasons for the lethal nature of this cancer is that most cancers are diagnosed too late once they have spread to other organs," Ahuja said. "Around 8 percent have spread to distant organs such as the liver or lungs, while another 10 percent have locally spread to major blood vessels. However, in the patients where cancer can be detected early and has not spread, a long-term cure is possible with surgical removal of the cancer with the surrounding lymph."
Ahuja's team had previously identified mutations in two genes, called BNC1 and ADAMST1, that typically occurred in the presence of pancreatic cancer. Since both mutations are found in 97 percent of early stage pancreatic cancer tissues, the researchers developed tests to search for signs of the mutations in blood samples collected from 42 people already diagnosed with early stage pancreatic cancer.
Reporting in the current online edition of the journal Clinical Cancer Research, Ahuja's team said both genetic markers were found in 81 percent of the tested blood samples, but not in samples taken from patients who either did not have pancreatic cancer or had a history of pancreatitis (an inflamed pancreas).
And Ahuja stressed that the test is not designed as a screen for the population as a whole -- only for those already deemed to be at high risk for the disease.
"The eventual goal is to develop a cost-effective test to test patients who are at high risk," she said. "The beauty of this test is that it can be repeated every year as you go for your annual physical."
Dr. Smitha Krishnamurthi is an associate professor of medicine in the division of hematology and oncology with University Hospitals Case Medical Center & Case Western Reserve University School of Medicine, in Cleveland. She applauded the research, saying that "if pancreatic cancer could be detected at an early stage, more patients would be cured."
"This study presents an encouraging step in the right direction," Krishnamurthi said. "The authors have developed a blood test that detected the earliest stage of pancreatic cancer and correctly identified most of the healthy individuals tested. However, this was a very small study. The blood test must be studied in many more patients with early stage pancreatic cancer and healthy individuals to really know if it will be an accurate and reliable screening test for pancreatic cancer."
I am praying for the day when a lab test becomes available because I, with our family history, will get it done as soon as one is available. In fact, I'd love to be a part of a university study regarding pancreatic cancer for people at high risk due to family history. If I ever hear of one, I will readily sign up for it.
But for today, I wear my purple ribbon in remembrance of my mom and the 40,000 other people who will fall victim to the disease each year.
