Hiroshima University Hospital has treated a significantly higher number of pancreas cancer patients and bile duct cancer patients compared to other high-volume medical institutions in the Western Japan.
Four faculty members maintain clinical practices and perform high volumes of complex operations using the latest technology and innovative procedures. Annually, our faculty members perform more than 100 pancreatic operations and more than 50 hepatobiliary operations. Hiroshima University Hospital resources include the latest in minimally invasive laparoscopic equipment and techniques (Figure 1).
This vast amount of experience treating hepatobiliary cancer and pancreas cancer allows patients to rely on Hiroshima University Hospital's Hepato-Biliary-Pancreatic cancer team for the highest quality of care
Figure 1. Volume of Pancreatic Operation and Major Hepatectomy Cases by Year
Hiroshima University Hospital is one of the premier medical centers for the treatment of pancreatic cancer. Our team of experts carefully create personalized care plans for every patient and are committed to using the latest, most innovative and advanced therapies to treat pancreas cancer. Multidisciplinary specialists focus on the diagnosis and treatment of pancreas cancer.
The prognosis for pancreatic carcinoma remains dismal. The chance of recovery (prognosis) and the treatment options depend on many things – whether the tumor can be removed by surgery, the stage of the cancer, the patient’s general health, and whether the cancer has just been diagnosed or has recurred.
Approximately 80% of the patients who diagnosed as pancreatic cancer are of unresectable and the overall 5-year survival rate is less than 10%. For the subpolulation of patients who have resectable tumors, the 5-year survival rate after complete tumor resection has been reported to be less than 20%.
Several multicenter randomized controlled studies (ESPAC-1 or -3, CONKO-001) presented that adjuvant chemotherapy using gemcitabine or fluorouracil plus folinic acid significantly improved overall survival of patients with pancreatic cancer after surgical resection, compared with surgical alone.
In 2002, our division implemented adjuvant chemotherapy using gemcitabine based chemotherapy for patients who underwent surgical resection of pancreatic cancer, and now expanded more patients initially diagnosed as “borderline” or “unresectable”.
In 2013, our faculty members reported the survival benefit of this adjuvant chemotherapy (Figure 2). Disease-free survival rates for over 100 patients who underwent adjuvant chemotherapy following surgery were 65 % at 1-year, 52 % at 2-years, and 39 % at 5-years with median disease-free survival time was 24.8 months (Murakami Y, Cancer Chemother Pharmacol 2013).
Our institutional policy is that adjuvant chemotherapy commences as soon as practical after patient recovery and our surgical team pursue prevention of postoperative complication to enable early initiation of adjuvant chemotherapy. The Hepato-Biliary-Pancreatic surgeons at Hiroshima University Hospital specialize in novel treatments for pancreatic cancer. They are attempting to improve outcomes with new treatment strategies incorporating results from our research program into the clinical realm. They are actively testing new agents in clinical trials to improve outcomes and patient survival.

Disease-free survival rates for over 100 patients who had postoperative adjuvant chemotherapy were 65 % at 1-year, 52 % at 2-years, and 39 % at 5-years with median disease-free survival time was 24.8 months.

Bile Duct Cancer (Cholangiocarcinoma)
Bile duct cancer, including carcinoma of the intrahepatic, hilar, distal and gallbladder, is a relatively uncommon malignancy in the United States and Europe, but in Japan, bile duct cancer is the sixth leading cause of all malignancies, and is responsible for more than 20,000 estimated deaths per year in Japan.
Prognosis depends on how early the cancer is caught, the patient’s overall health and how well the liver and ducts are functioning. Overall 5-year survival rates of patients with bilie duct cancer, including patients with resectable and unresectable tumors, have been reported to be 20% in Japan. Treatment varies depending on how far the cancer has advanced and the size of the tumor. It may include surgery, chemotherapy, radiation or other treatments
Ground breaking Research
Our faculty member have pioneered several advances in bile duct cancer, including:
・Adjuvant chemotherapy (given after surgery), gemcitabine, which now is standard treatment around the world
・Neoadjuvant chemotherapy (given before surgery) to shrink the tumor and allow it to be removed surgically with less damage to normal tissue.
・Treatment plan tailored to chemosensitivities
In 2002, our faculty members administrated adjuvant gemcitabine-based chemotherapy for patients with bile duct cancer after surgical resection and reported the promising survival benefit in the patients after postoperative adjuvant chemotherapy (Figure 3).
Survival rate for 98 patients who underwent postoperative adjuvant chemotherapy were 47 % at 5-year with median overall survival time was 49.6 months, which is significantly longer compared with patients who did not undergo postoperative adjuvant chemotherapy.
If surgery is possible, our approach to bile duct cancer as well as pancreatic cancer usually is to complete chemotherapy before surgery particularly in patients with advanced stage. This method increases chances the tumor can be removed completely, helps chemotherapy be more effective, and makes for better recovery.
Hiroshima University Hospital is leading research into ways to treat and prevent Hepato-Biliary-Pancreatic cancer. This means Hiroshima University Hospital is able to offer a wide range of clinical trials for new treatment

Lower gastrointestinal tract
Introduction of departments
The physicians in the Division of Colon and Rectal Surgery specialize in the surgical treatment of disorders involving the colon, rectum, anus, and small intestine. Furthermore, the Division physicians treat benign and malignant conditions and perform routine screening examinations. Additionally, we work closely with gastroenterology colleagues, as well as other specialists, to ensure that patients receive the most comprehensive, innovative, and supportive care.
The Division of Colon and Rectal Surgery performs more than 200 operations each year. Approximately one-half of the surgeries involve inflammatory bowel disease (IBD; ulcerative colitis and Crohn’s disease); thus our Division is one of the premier surgical centers for IBD in Japan.
The Division utilizes a multidisciplinary approach for colon and rectal cancers to achieve better clinical outcomes. For locally advanced rectal cancer, we offer neoadjuvant chemoradiotherapy, when indicated. Surgeries are most often performed using minimally invasive (laparoscopic) techniques, which have many benefits, including less blood loss and trauma, a shorter hospital stay, and a more rapid recovery, than conventional surgery.
Additionally, the Division offers a variety of physiologic tests and procedures, including anorectal manometry, defecography, and biofeedback to treat fecal incontinence, constipation, and a variety of pelvic floor disorders. Another innovative modality, sacral nerve modulation therapy, was approved in Japan in the spring of 2014 as a treatment for fecal incontinence.

Introduction of departments
Prof. Hideki Ohdan
Director, Gastroenterological Surgery
Our department has treated diseases of the digestive tract, chest, peripheral vessels, endocrine system, as well as a broad range of other diseases, which is consistent with the slogan "from head to toe." However, a recent medical complication requires the acquisition of advanced technology that may inhibit medical improvement if we try to cover all fields. Therefore, we will now specialize in treating various diseases of the abdominal organs such as the stomach, small intestine, large intestine, liver, biliary tract, and pancreas, as well as perform liver, kidney and pancreas transplant procedures. To provide the best medical treatment for patients, we have four groups of experts working on the upper and lower gastrointestinal tracts, hepato-biliary-pancreatic systems, and in transplantation. Each group works hard as a unit to promote medical examination, research, and education. Some common concepts that describe our department include "traditional succession," "changes that focuses on environmental adaptation," and "development of medical treatments for the next-generation."
All surgeons must aim for the most minimally invasive techniques available for all operations to minimize complications and prevent the relapse of the primary diseases. To perform the ideal surgical operation, it is important to receive the necessary training under the appropriate educational system that provides the organization’s basis for obtaining knowledge, discernment, ideas, and technology. We provide this kind of training system to support young and senior surgeons.
Occasionally, great ideas are born from a difficult clinical situation. Our department aims to train surgeon scientists/academic surgeons who can link new discoveries with ideas for developing new medical treatments while also sympathizing with their patient's pain.
We believe in research that takes patient treatments “from the bench to the bedside.”
