This article discusses the symptoms and latest treatments for pancreaticRelating to the pancreas. Pancreatic cancer is the fifth leading cause of cancer-related death in the United Kingdom with more than 8000 new cases diagnosed every year.
The reason for such a low operability rate is related to the very menacing nature of this cancer, which frequently only becomes obvious when it is too late for surgery. Several risk factors have been identified in cancer of the pancreas, and smoking remains the strongest link. Early diagnosis is vital as demonstrated by the correlation between stage of the tumour and survival in the table below. Tumour limited to the pancreas or spread beyond without involving bloodA fluid that transports oxygen and other substances through the body, made up of blood cells suspended in a liquid.
In general, those patients treated with surgery survived longer, while those not treated with surgery fared worse.
An abdominalRelating to the abdomen, which is the region of the body between the chest and the pelvis. In jaundiced patients, a special MRIAn abbreviation for magnetic resonance imaging, a technique for imaging the body that uses electromagnetic waves and a strong magnetic field. The pancreas is located behind the stomach and is attached to the duodenumThe first part of the small intestine., the first part of the intestineThe section of gut, or gastrointestinal tract, from the stomach to the anus. The continuity of the stomach and bile duct is restored by joining them with a loop of intestine. On the other hand, if the cancer is located in the body or tail of the pancreas, the standard operation is a distal pancreatectomySurgical removal of the pancreas. Resection of pancreatic cancer involves major surgery, especially for tumours in the head of the pancreas, as the Whipple’s operation is one of the most invasive and complex surgical procedures. Patients have to be generally fit to undergo major surgery and will routinely undergo a full pre-operative check-up to assess their cardiorespiratoryRelating to the heart and lungs., renalRelating to the kidney. If surgery is uncomplicated patients are expected to be discharged approximately one to two weeks later, although complete recovery can take as long as three months.
Results from the largest randomised controlled trialA study comparing the outcomes between one or more different treatments for a disease (or in some instances, preventive measures against that disease) and no active treatment at all (the placebo group). As surgical resection remains the gold standard treatment and the only one to confer potential long-term survival, all efforts should be made to make these patients operable, although several studies have suggested that the long-term survival of patients with residual tumour left behind microscopically (so called R1 resection) can be similar to patients who undergo a curative resection with clear margins (R0 resection), the intention is quite clearly to eradicate the tumour completely. In the absence of metastatic spread, the most common contraindication to operate is the encasement of the arterial vessels.
A therapy that gives relief from the symptoms of a disease rather than impacting on its course.
However, even with the most aggressive and sophisticated techniques, the majority of patients with locally advanced pancreatic cancer remain inoperable. Soon after surgery, patients are usually transferred to Intensive or High Dependency Care, where they can be closely monitored for the first 24 hours before they go back to the surgical ward.
Patients are mobilised a few hours after their operation and frequently sit on a chair on the first post-operative day.

When the pancreas and duodenum are flipped over and the pancreas dissected, you will be able to identify the ducts of the pancreatic system.
Note that the major pancreatic duct merges with the common bile duct to form a swelling in the duodenal wall called the ampulla (of Vater).
The Keck Division of Hepatobiliary and Pancreatic Surgery offer a comprehensive multi-disciplinary program in pancreas, bile duct and liver cancers. Our team also offers minimally invasive laparoscopic and robotic procedures for liver and pancreatic cancer and we have amongst the largest experience in the world for these procedures. The USC Hepatoma program provides comprehensive treatment for liver cancer with specialists from different specialty including liver surgeons, liver transplant surgeons, medical oncologists, hepatologists and radiologists offering comprehensive treatment options that includes liver transplant, laparoscopic and robotic surgery, percutaneous and surgical radiofrequency ablation, intra-arterial chemotherapy and clinical trials. The way men are treated for prostate cancer is set to change with the launch of the world’s largest national prostate cancer registry incorporating clinical data alongside patient feedback of their lived experiences. The Prostate Cancer Outcomes Registry – Australia and New Zealand (PCOR-ANZ) is housed in the School of Public Health and Preventive Medicine (SPHPM) at Monash University. Launched by the Movember Foundation, thanks to funds raised by the Movember community, the registry spans across all states and territories in Australia and New Zealand, equipping clinicians with the information they need to minimise the risk of life-changing side effects and redefine what treatment success looks like.
Associate Professor Sue Evans, Head of the Clinical Registry Unit at SPHPM, said the registry will bring urologists and oncologists together to redefine what success looks like for prostate cancer treatment and life beyond the disease. Men who have gone through treatment for prostate cancer are often left with adverse effects that seriously impact their ability to live a normal life, including incontinence, sexual and intimacy issues and psychological distress.


In Australia, prostate cancer is the most commonly diagnosed cancer in men, with around 120,000 men living with the disease and this is expected to rise to 267,000 by 2017. The expansion of the national registry to incorporate data from all states follows successful registries in Victoria and South Australia.

Being a physician administrator, Dr Wadhwa is a key liaison, coordinating quality control and regulatory procedure of a National Cancer Institute (NCI)-funded The Cancer Genome Atlas project. The prognosis of pancreatic cancer has historically been very poor with approximately 3% of patients alive five years after diagnosis. A recent study demonstrated that approximately one third of pancreatic cancers in the UK in 2010 were caused by smoking. Unfortunately screening is not a feasible option as the incidenceThe number of new episodes of a condition arising in a certain group of people over a specified period of time.
Lymph accumulates outside the blood vessels in the intercellular spaces of the body tiisues and is collected by the vessels of the lymphatic system.
The behaviour of neuroendocrine tumours can be aggressive but very often they are quite benignNot dangerous, usually applied to a tumour that is not malignant. In this procedure, known as the Whipple’s operation, the head of the pancreas is removed together with the duodenum, the bile duct, the gallbladderSmall pear-shaped organ that sits under the liver and that stores bile. The pancreatic stump can be joined to the intestine (pancreato-jejunostomy) or to the back of the stomach (pancreato-gastrostomy – Figure 5).
There is a clearly demonstrated correlation between large workload and good results at hospitals and clinics and is a convincing reason to choose high volume centres for this type of surgery.
Improvement in peri-operativeThe entire duration of a surgical procedure, from pre-operative steps to post-operative recovery. Standard downstaging or neo-adjuvant chemotherapy with gemcitabine can shrink the tumour in a relatively small number of cases.
In this case, the tumour is involved in, or even wraps around, the main arterial structures, precluding any surgical treatment, as arterial reconstruction is not a feasible option. In our Institution, we have extensive experience in treating patients with locally advanced disease and to date we have not recorded any post-operative death after vascular reconstruction of the portal vein in patients undergoing pancreatic surgery. Various treatment modalities have been described in patients with locally advanced and inoperable pancreatic cancer including Cyberknife®, radiofrequency ablation and photodynamic therapy. An epiduralOn or over the dura mater, the outermost of the three membranes covering the brain and spinal cord. Although they can usually have some sips of water, proper oral intake is not allowed for the first four or five days. Our team which includes medical oncologists, liver and pancreatic surgeons, radiologists and radiation oncologists offer state of the art treatment including neoadjuvant chemotherapy, Gamma knife radiation, minimally invasive surgical removal of liver and pancreas tumors, complex surgeries to remove tumors that are adherent to blood vessels and clinical protocols for patients with advance pancreas and liver cancers. Studies have shown that for good outcomes from the Whipple surgery, the experience of the center and the surgeon is important. Laparoscopic surgery offer much faster recovery and less complications compared to open surgery.
The registry gives doctors (and future patients) the most comprehensive insight into men’s quality of life after they are diagnosed and treated for prostate cancer. This will equip doctors with the data they need to minimise the risk of life-changing side effects and redefine what success looks like to transform the treatment and care of prostate cancer patients,” said Associate Professor Evans. In the future we will be able to compare clinical outcomes across the globe and, as a result, help minimise side effects of treatment,” Associate Professor Evans. For men living with prostate cancer, there are a variety of treatment options now available which vary according to the type of prostate cancer diagnosed but can include: active surveillance, hormone therapy, surgery, radiotherapy or a combination of therapies.
She has been actively involved in research focusing on molecular carcinogenesis of gastroesophageal cancer and upcoming targeted therapies for advanced gastric cancer. Surgical resection remains the only potentially curative option and is associated with a 5-year overall survival rate of between 10 and 15%, but can only be performed in less than 20% of cases.
Most of these patients will require a camera test, called Endoscopic Retrograde Cholangiopancreatography (ERCPAn abbreviation for endoscopic retrograde cholangiopancreaticogram.), to stentA tube placed inside a tubular structure in the body, to keep it patent, that is, open.
The pancreas sits on the two largest blood vessels in the body, the inferior vena cavaThe large vein that carries de-oxygenated blood from the lower half of the body to the heart. Again, there is good clinical evidence that neither of the two techniques is superior to the other and this is purely down to personal preference and experience of the operating surgeon.
Advanced age is not an absolute contraindicationA condition which may make a medical treatment or procedure inadvisable.
May be abbreviated to RCT., ESPAC-1, have demonstrated a clear benefit in adjuvant chemotherapyThe use of chemical substances to treat disease, particularly cancer. However, recently, a new chemotherapy regimen with 5-Fluorouracil, irinotecan and oxaliplatin (folfirinox) has been associated with a response rate as high as 30%. On the contrary, if the portal vein is involved, surgery is possible by removing the vein together with the cancer and joining the two ends of the vein together. These techniques utilise different forms of energy in the attempt to locally destroy the tumour but none of them has been proven to be curative and should be regarded as palliative therapies. The epidural space is used for anaesthetising spinal nerve roots, for example during pregnancy., a small anaestheticA medication that reduces sensation.


In the majority of the cases complications can be resolved with radiological or simple medical intervention, such as intravenous feeding and antibioticsMedication to treat infections caused by microbes (organisms that can't be seen with the naked eye), such as bacteria.. This ampulla then empties into the descending part of the duodenum at the major duodenal papilla. We presently offer laparoscopic Whipple operation, pancreatic resections, enucleation of tumors and liver removal. She has researched the incidence of brain metastases following trimodality therapy in patients with esophageal and gastroesophageal cancer. This is primarily because the cancer is either too advanced locally, or it has already spread to other organs, particularly to the liverA large abdominal organ that has many important roles including the production of bile and clotting factors, detoxification, and the metabolism of proteins, carbohydrates and fats.
A special blood tumour marker known as CA 19-9, is high in two thirds of patients with pancreatic cancer. A variant of this procedure adopted by many surgeons is the PPPD, or pylorus preserving pancreato-duodencetomy, where the whole stomach is preserved (Figure 4).
Laparoscopic or keyhole surgeryA type of minimally invasive surgery., sometimes performed for benign or neuroendocrine tumours in the tail of the pancreas, is very rarely considered for cancer, although a few laparoscopicA keyhole surgical procedure.
This improvement is also associated with a better management of the complications, which occur in approximately 30% of cases. In responsive patients a short course of chemoradiotherapyTreatment of cancer with both chemotherapy and radiation therapy. In cases where the gap is too large to approximate the two ends, the missing part of the portal vein is replaced with a graft, commonly taken from the jugular vein (Figure 6).
Cyberknife®, the most promising of these, has been used with some success in selected cases of localised recurrence after surgical resection. There may not be an accessory pancreatic duct but if there is, its opening is located a couple of centimeters above the major papilla at the minor duodenal papilla. We also specialize in complex operations required in patients with very large cancers of the liver and pancreas where the cancer is adjacent to or involving a major blood vessel. Screening would not be cost effective and it would also require invasive diagnostic modalities, which in themselves carry a risk. A contrast enhanced CTThe abbreviation for computed tomography, a scan that generates a series of cross-sectional x-ray images scan is the gold standard pancreatic screening test if a reasonable suspicion exists. Cellular material can also be obtained to confirm a cancer diagnosis (known as brushing cytologyThe study of cells, in medicine used to mean examination of cell samples under a microscope.).
Clinical trials have clearly demonstrated no difference in the short- or long-term outcome between the two techniques, though patients undergoing PPPD are more likely to have difficulty in emptying the stomach as the pyloric sphincterA ring of muscle around a natural opening or passage that acts as a valve, regulating inflow or outflow. The most serious side effects of pancreatic surgery include bleeding, infectionInvasion by organisms that may be harmful, for example bacteria or parasites. In patients with inoperable or recurrent disease, attention should be concentrated on the quality of life, pain relief and the nutritional status of these unfortunate patients, which can be improved with palliative chemotherapy.
She has extensive experience in gastrointestinal cancer biology, gene transcription and expression regulation, as well as molecular approaches to investigations of cellular mechanisms of oesophageal cancer initiation, transformation and progression. To date there is not a national screening programme for pancreatic cancer and prompt investigation of suspicious symptoms remains the best chance for an early diagnosis. There are cases, however, where the diagnosis is uncertain, either because a definite mass cannot be identified on a CT scan or because the features of the lesiona general term to cover any abnormality such as a wound, infection, abscess or tumour. The ongoing ESPAC-4 trial is currently recruiting and enrolling patients to compare adjuvant gemcitabine alone versus combination chemotherapy with gemcitabine and capecitabine. People with at least one first-degree relative diagnosed with pancreatic cancer have almost double the risk of someone without a family history of pancreatic cancer.
In some cases where a pancreatic fistula occurs or the gastric function is impaired, a period of intravenousWithin a vein.
He earned his PhD from the University of Texas at Dallas and worked as a basic research fellow at the Laboratory of Experimental Carcinogenesis, Center for Cancer Research, National Institutes of Health, Bethesda, MD, USA.
In these cases a biopsyThe removal of a small sample of cells or tissue so that it may be examined under a microscope. It is caused by a build up of bilirubin in the blood., with yellow discoloration of the skin, dark urine, pale stools and itching. In this procedure, an endoscopic probe is deployed in the stomach and the tumour is visualised and biopsied. AjaniDr Ajani is a medical oncologist with 30 years of experience with clinical and translational research on gastric and oesophageal cancers. He is particularly interested in overcoming resistance to systemic therapy and radiotherapy that is inherent in gastric and oesophageal cancers.
A Positron Emission Tomography (PET) scan, a nuclear medicine, can be used in selected cases, mainly to clarify metastatic disease such as dubious liver and lung lesions or enlarged lymph nodesSmall, rounded organs of the immune system that are distributed along the lymphatic system that filter lymph, a fluid derived from the blood, and produce antibodies and a type of white blood cells, lymphocytes..
