Pancreatic cancer has the lowest survival rate among all major cancers, largely because physicians lack diagnostic tools to detect the disease in its early, treatable stages. Now, a team of investigators led by Lev T. Perelman, PhD, Director of the Center for Advanced Biomedical Imaging and Photonics at Beth Israel Deaconess Medical Center (BIDMC), has developed a promising new tool capable of distinguishing between harmless pancreatic cysts and those with malignant potential with an overall accuracy of 95 percent. The team’s preliminary data was published online in the journal Nature Biomedical Engineering.
The new device uses light scattering spectroscopy (LSS) to detect the structural changes that occur in cancerous or pre-cancerous cells by bouncing light off tissues and analyzing the reflected spectrum. The results could help guide physicians’ decision making when considering whether the presence of pancreatic cysts requires surgery, a high-risk procedure. Today, because of the lack of less-invasive diagnostic methods, more than half of these procedures turn out to have been unnecessary.
“About one-fifth of pancreatic cancers develop from cysts, but not all lesions are cancerous,” said Perelman, who is also Professor of Medicine and Professor of Obstetrics, Gynecology and Reproductive Biology at Harvard Medical School. “Considering the high risk of pancreatic surgeries and the even higher mortality from untreated pancreatic cancers, there’s an obvious need for new diagnostic methods to accurately identify the pancreatic cysts that need surgical intervention and those that do not.”
In Perelman and colleagues’ series of experiments, the LSS technique achieved 95 percent accuracy for identifying malignancy. Cytology — the only pre-operative test currently availably — is accurate only 58 percent of the time. While the new technique requires further testing, LSS could represent a major advance against pancreatic cancer.
“This tool is a technology that is transformative in the evaluation of pancreatic cysts,” said co-lead author Douglas K. Pleskow, MD, Clinical Chief of the Division of Gastroenterology and Director of the Colon and Rectal Cancer Program at the Cancer Center at BIDMC. “It provides a high level of precision in the detection of potential malignant transformation of these cysts.”
Pancreatic cysts are common, and today’s high-definition scanning technologies like MRI and CT imaging are detecting them with increasing frequency. Despite their high resolution, these scanners provide doctors with limited information about cysts’ malignant potential.
Currently, physicians rely on minimally-invasive fine needle aspiration (FNA) biopsies to test pancreatic cysts for malignancy. The biopsy removes fluid from the cysts, which is then analyzed for cancer cells and other telltale signs of the disease, a process called cytology. However, the test fails to detect cancer about half the time, leaving high-risk surgery as the current gold-standard means of diagnosing pancreatic cysts.
To test the accuracy of the LSS system, Perelman and colleagues collected and analyzed the reflected light from 13 cysts taken from recent surgeries. Next, they compared their findings with the results from pre-operative imaging, FNA biopsies and post-operative tissues analysis. In all cases, the LSS diagnosis agreed with the post-operative analysis.
In a second experiment, the LSS tool was tested in 14 patients with pancreatic cysts who were undergoing the standard FNA biopsy. Measuring less than half a millimeter in diameter, the miniature experimental LSS fiber-optic probe was inserted in the FNA needle. Physicians spent two minutes or less measuring optical spectra from the internal cyst surface before collecting fluid from the cysts as part of the traditional biopsy. Out of nine patients whose cysts had been definitely diagnosed as either cancerous or benign, all were correctly identified by LSS.
Next, the researchers will assess the LSS system’s accuracy by continuing to analyze post-operative tissues as they become available.

Acute pancreatitis may be an indicator for pancreatic cancer at an earlier stage, according to a study published in Medicine.
Shaojun Li, M Med, and Bole Tian, PhD, from the West China Hospital in Sichuan, China, identified 47 consecutive patients with pancreatic cancer who presented with acute pancreatitis between January 2009 and November 2016. Of the patients, 35 (74.5%) were men with a mean age of 52 years. Clinical features, clinicopathologic variables, postoperative complications, and follow-up evaluations of patients were recorded from the database.
Clinical features of acute pancreatitis include abdominal pain, jaundice, and weight loss. The timing of surgery was identified by receiver operating characteristic (ROC) curve. Preoperative, intraoperative, and postoperative parameters were collected to determine operative timing of surgical intervention. Survival curves were plotted using the Kaplan—Meier method, and survival data were analyzed using the log-rank test.
Of the 47 patients included, acute pancreatitis was clinically mild in 45 (95.7%) and severe in 2 (4.3%). Radical surgery was performed in 32 (68.1%) of cases, palliative surgery in 7 (14.9%), and biopsies in 8 (17.0%). A total of 2 (8.0%) patients were needed for vascular resection and reconstruction. The diagnosis of pancreatic cancer occurred at a median of 101 days, and 27 (57.4%) patients were diagnosed in less than 2 months after acute pancreatitis diagnosis.
The timing of surgery was calculated from the date of the first attack of acute pancreatitis to the surgery. The best cutoff point was 24.5 days according to the ROC curve. A total of 25 (64.1%) patients received surgery at or before 24.5 days from diagnosis of pancreatic cancer. Postoperative complications occurred in 12 (30.8%) patients. The median follow-up for patients was 24 months with a patient survival rate at 1 year of 23.4%. The median survival in patients with vascular resection and reconstruction was 18 months, compared with 10 months in patients without vascular resection.
According to the authors, “this retrospective study supports the assumption that acute pancreatitis is the early presenting clinical symptom of pancreatic cancer.”

Nutrition, though often overlooked, plays a key role in mitigating the symptom burden of patients with pancreatic cancer.
When diagnosed with pancreatic cancer, one of the last things on a patient’s mind may be diet and nutrition, yet these are two key components that medical experts say can affect the outcome of treatment.
Patients with pancreatic cancer often experience weight loss, loss of appetite, fatigue, nausea, as well as back and belly pain. The cancer itself plays a large role in preventing patients from having a normal diet and nutrition.
During a live broadcast of CURE Connections, held during the Seventh Annual Ruesch Center Symposium: Fighting a Smarter War on Cancer on Dec. 3 in Washington, D.C., a panel that included an oncologist, a nurse, an oncology dietitian and a patient advocate discussed the importance of nutrition when trying to manage a long list of symptoms.
“These cancers are well-known to release hormones that we don’t fully understand that rob a patient of their appetite,” said Michael Pishvaian, M.D., director, Phase 1 Clinical Trials Program, Division of Hematology/Oncology, Georgetown Lombardi Comprehensive Cancer Center. “It makes them feel like they don’t want to eat or drink anything. It robs them of their calories even if they are very conscientious about getting enough nutrition in. It can even cause changes to taste, so a patient with pancreatic cancer will often complain about an abnormal taste sensation long before they even start chemotherapy.”
Pishvaian explained that the pancreas creates digestive enzymes that help digest food properly. When the cancer invades the pancreas, this disrupts proper digestion. The lack of digestion also leads to bacterial overgrowth lower down into the gastrointestinal (GI) tract and can cause a lot of discomfort, gassiness, bloating and diarrhea, he added.
There are ways to try to manage these symptoms before, during and after the cancer journey. The panel recommended patients make it a priority to meet with a dietician one-on-one. Some cancer centers already have a dietician in place.
“Often pancreatic cancer patients will undergo a surgery called a Whipple Procedure (pancreaticoduodenectomy), which can impair a patient’s ability to digest certain foods like fats, carbohydrates and proteins – particularly in fats,” said Rachel Wong, R.D., oncology dietician, Georgetown Lombardi Comprehensive Cancer Center.
She added, that this is where digestive enzymes, which help break down fats, proteins and carbohydrates, should be consumed with meals and snacks.
Patients should consume energy-dense nutritious foods such as quinoa, oatmeal and avocado, which all have healthy fats. As far as sugars go, they should continue to eat fruits, but stay away from simple sugars like candy bars.
It is also recommended that patients with pancreatic cancer eat small, frequent meals, eat slowly and also keep a diary of everything they are eating and drinking each day.
Patricia Reilly, a holistic health counselor, nutrition expert and patient advocate, says the best way a caregiver can be there for a loved one with pancreatic cancer is to help with nutrition. She became that person for her husband, who had pancreatic cancer.
“We recognized that he wanted to feel good every day. As a caregiver, I looked at the foods,” Reilly said. “I want my doctor to know about those clinical trials. I want him to be on top of that and let me create a team to support my husband in terms of what he’s eating for breakfast, lunch and dinner, again looking for nutrient-dense foods that will support him to be stronger so he will get to that clinical trial.”
The panel also opened up the discussion on marijuana and if there is a benefit there for patients with pancreatic cancer, which they agreed there is.
“We are seeing that their appetite goes up, their sense of well-being is greater and their pain levels are reduced,” said Pishvaian. “It is not a treatment for their cancer, but universally makes them feel better. Try things, see what works and stick with it.”

Holidays are traditionally viewed as a time to celebrate. Many people enjoy reuniting with family and friends, giving and receiving gifts, and celebrating religious traditions during this time. However, sometimes people with cancer and their loved ones feel “out of step” from the rest of the world during the holidays. In fact, the holiday season can prompt new questions, such as: How do I take care of the holiday rush and myself at the same time? How can I celebrate when I have so many other things on my mind? What will my life be like next year? Sharing these concerns with the people you love and who love you can help you feel more connected.
Here are some additional tips for coping with cancer during the holidays:
Make plans to get together with friends, family or co-workers over the holidays. Trying to celebrate alone can be very difficult, so accept some invitations from others, or join an organized group activity through your local YMCA, YWCA, church or synagogue. Find the right balance between celebrating with family and friends and spending the time you may need on your own. Give yourself permission to pace your activities and to decline an invitation or two so that you have the energy to enjoy the gatherings that are most important to you.
Create a new holiday season tradition that makes the most of your energy.Change your usual holiday activities so you relieve yourself of some of the pressures of entertaining. Have a “pot luck,” with family members each bringing a dish for the meal, have someone else host the meal, or suggest eating out at a favorite restaurant.
Enjoy special moments. Try to focus on new traditions that have been established, rather than dwelling on how cancer has changed a holiday or special occasion.
Talk to your health care team about upcoming special events. They may be flexible about appointments in order to accommodate travel or other needs.
Be an innovative shopper or gift giver. Use mail order catalogues, shop over the telephone, or try online shopping this year. You can also make a gift of sharing your thoughts and feelings. Write a short note or make a phone call to let others know that you are thinking about them.
Express your feelings in ways that help you receive the support of the important people in your life. Tears can bring a sense of relief. Laughter can be relaxing. Sharing can be comforting. It is common to experience a mixture of anticipation, excitement and apprehension about the future. Let your feelings breathe, and talk them over with a loved one, friend or professional counselor.
Celebrate strengths you and your loved ones have developed. Many families who face the day-to-day challenges of cancer discover strengths and courage they didn’t know they had. Reflect on the strengths you have developed, and build on them during the holidays.

Symptoms of pancreatic cancer can be weight loss, abdominal or back pain, diabetes, or jaundice. Physical symptoms are not very specific to the disease and are often mistaken for something else. Patients can even be asymptomatic. The bottom line is pancreatic cancer is hard to diagnose and even harder to treat. Nikki Mitchell Foundation is working hard to prevent, detect and cure pancreatic cancer.
Jamie Thornton, a friend of NMF, shares the story of her father’s journey:
My father, James Drury, was a Vietnam veteran (a captain and platoon leader), a general manager, and a great leader and father. He loved life, outdoors, people and food. He was a heavy-set guy and we were excited at first when he started to lose weight, but when he started having severe pain in his stomach, he finally went to the doctor. The doctor was positive about his weight loss and encouraged him to keep cutting back on food.
Around November, a few months after the initial pain and losing 50 pounds, he started hurting a little more when he ate and I talked him into going back to the doctor twice. By the end of the week we had a diagnoses of a tumor in his pancreas. After a slew of hospital visits and tests, we found out he had two pancreatic tumors, with one on a lymph node, liver tumors, and spots in his lungs. The oncologist recommended he start chemotherapy and also participate in an additional clinical trial that might decrease the spread of the tumors from the lymph node.
Throughout all of this, Dad was very positive and strong in his faith and believed that with any outcome he was a winner because he either got to stay with us on earth or go to heaven.
We scheduled the chemo and he made it through only two treatments. After the second round was over, Dad could barely stand up. He had an adverse reaction to the drugs, wound up in the hospital twice, and then we were told he only had a few weeks to two months to live. We were sent home with hospice care.
We were blessed that Daddy came out of hospital feeling better this time and over the next month, as the chemo left his body, he was able to return to some fun activities that he enjoyed like fishing, shooting and visiting with friends he hadn’t seen in years. He actually had a full pain-free week once and felt like maybe he was cured. Then, at the end of May, and after watching my daughter graduate from middle school, he started declining rapidly. A week and half later he was gone. I believe he is a winner in that he is in heaven and he has left a wonderful legacy to his kids, grandkids, friends and family. He maintained a wonderful outlook throughout the whole experience.
We experienced some difficulties, like doctors not being clear about survival rates and honestly explaining to us what to expect. I also wish we had known earlier that weight loss is a major indication that something is wrong and that maybe he could have had a chance of beating the disease.
“They said I was too fat, too black, too short and too old,” powerhouse singer says. “And look at me now.”

The trailer for Miss Sharon Jones!, the documentary that traces soul singer Sharon Jones’ career and ongoing cancer battle over the course of a harrowing year, has been released. The Barbara Kopple-directed film will open in New York and Los Angeles this summer with plans to expand nationwide.
The inspiring clip opens with snippets of Jones’ career accomplishments, from concert footage to late night TV appearances. But before she received hard-won attention in the national spotlight, she worked odd jobs, including serving as a corrections officer, and had to combat ageism and more. “It was tough. They said I was too fat, too black, too short and too old,” she says in the trailer. “And look at me now. All this hard work is finally paying off.”
However, in 2013 as Sharon Jones & the Dap-Kings were about to release a new album and tour, Jones was diagnosed with pancreatic cancer. The trailer showcases her triumphant survival spirit as she returns to the stage. “The show must go on,” she says.
In September 2015, Jones revealed her cancer had returned. However, she and the band continued to tour while she underwent chemotherapy. “I’m going to do what I have to do. I’m going to sing,” the singer said at a documentary screening during the Toronto International Film Festival, adding that her diagnosis won’t keep her from “giving the people what they want.”
Miss Sharon Jones! opens on July 29th in New York and August 5th in Los Angeles.
