Primary ImpressionObstructive jaundice secondary to Pancreatic head mass r/o pancreatic ductal adenocarcinoma
![Page 30: The Curious Case of John Dick](https://reader036.vdocuments.mx/reader036/viewer/2022081505/56816643550346895dd9b91e/html5/thumbnails/30.jpg)
• Incidence rate 37,700 cases in the US, leading to 34,300 deaths.• No predilection between genders• Incidence is more common within the elderly
population• No established early warning symptoms• Overall 5-year survival rate, <5%
Pancreatic Adenocarcinoma
![Page 31: The Curious Case of John Dick](https://reader036.vdocuments.mx/reader036/viewer/2022081505/56816643550346895dd9b91e/html5/thumbnails/31.jpg)
•Causes are still unknown although it is considered that environmental causes play a role:
• Cigarette smoking
• Obesity
• Chronic pancreatitis
• History of diabetes mellitus
• Diet (increased intake of red meat or dairy products)
Pancreatic Adenocarcinoma
![Page 32: The Curious Case of John Dick](https://reader036.vdocuments.mx/reader036/viewer/2022081505/56816643550346895dd9b91e/html5/thumbnails/32.jpg)
• Said to arise from a series of gene mutations• Early on its onset, the mass would originate
within the area of the ductal epithelium and would gradually spread to adjacent areas.• Pancreatic intraepithelial neoplasia
invasive carcinoma• Activation of the KRAS2 oncogene and
inactivation of the tumour suppressor genes CDKN2A and TP53
Pancreatic Adenocarcinoma
![Page 33: The Curious Case of John Dick](https://reader036.vdocuments.mx/reader036/viewer/2022081505/56816643550346895dd9b91e/html5/thumbnails/33.jpg)
•Presentation of the symptoms would greatly depend on the area where the tumour is located.
•In 80% of cases, the tumour would be located within the area of the pancreatic head and this would have a great likelihood to cause obstructive cholestasis.
•Abdominal pain or discomfort as well as nausea are common clinical presentations.
Diagnosis and staging
![Page 34: The Curious Case of John Dick](https://reader036.vdocuments.mx/reader036/viewer/2022081505/56816643550346895dd9b91e/html5/thumbnails/34.jpg)
• Systemic signs would include weakness, weight loss as well as anorexia.• Physical examination:
• Signs of jaundice• Wasting • Hepatomegaly• Ascites
• Routine laboratory tests might reveal anemia, abnormal liver function tests and hyperglycemia.
Pancreatic Adenocarcinoma

Pancreatic Adenocarcinoma•Common complaints would include
abdominal pain with the possibility of radiating to the back.
•Weight loss•Splenomegaly, varices in the stomach
and esophagus, GI bleeding•DM symptoms, glucose intolerance
