A 55 year old man presents to a physician with jaundice. Ultrasonography demonstrates a 5 cm mass in the head of the pancreas. Endoscopic retrograde cholangiopancreatography with cytologic sampling demonstrates cells with large hyperchromatic nuclei and a high nuclear/cytoplasmic ratio. A few small glands composed of these cells are also seen in the cytologic preparation. The overall prognosis for this man will be most similar to that of a patient with which of the following malignancies?
The patient probably has pancreatic adenocarcinoma. This cancer carries one of the worst prognoses, with a 3.5% overall 5 year survival rate despite all attempts at aggressive management. The prognosis is also bleak with adenocarcinoma of the esophagus, with a 10% overall 5 year survival rate. Adenocarcinoma of the breast now has an overall 5 year survival rate of 60-70%. Adenocarcinoma of the colon now has an overall 5 year survival rate of 50-60%. Adenocarcinoma of the prostate now has an overall 5 year survival rate of 50-70%.
