‘Classic’ symptoms Obstructive Jaundice –50% –Truly ‘painless’ in about 10%, most will have some pain, but not biliary colic Pain –70% –Back / epigastrium –Relieved by sitting forward Nausea / Vomiting Weight Loss Anorexia

Other symptoms New onset type 2 diabetes mellitus –underweight or normal weight patient, not associated with weight gain Resistant dyspepsia/persistent epigastric pain IBS like symptoms in those >45 years –very rare as a new onset symptom at this age Altered bowel habit –Increased bowel movement frequency and offensive smelling stools –Suggestive of exocrine insufficiency Venous Thromboembolism –may be a manifestation of an underlying abdominal malignancy

Blood tests Full blood count –anaemia rare except for ampullary tumours Liver function tests –Obstructive jaundice –Elevated gamma GT / Alk Phos may precede bilirubin Serum glucose –Diabetes or impaired glucose tolerance CA19-9 –Sensitivity of ~80% and a specificity of 83% –Normal levels do not exclude diagnosis –Better for treatment monitoring

Investigations U/S –Often first line for jaundice –May demonstrate pancreatic mass Contrast-enhanced CT –Gold standard –Essential for staging

Chemotherapy >80% now receive adjuvant chemotherapy after surgery (Gemcitabine +/- others) Minority of unresectable patients fit for palliative chemotherapy (Folfirinox) –50% if locally advanced –36% if metastatic Role of neo-adjuvant chemotherapy currently being explored –ESPAC-5

Long-term survival rates - post resection 1 year survival 61% >75% 5 year survival 6% >25% X 2 LR =12.70 P<0.001

Summary Pancreatic Cancer is the 9 th commonest cancer in the UK It is the 5 th commonest cause of cancer death Notoriously late presentation, early metastases and poor survival rates Vague symptoms If diagnosed early enough for surgical resection, then chances of surviving beyond five years increase ten-fold
