New Delhi, March 18, 2019:
Let us take a quick recap on pancreatic cancers.
- Cancer of the exocrine pancreas is a highly lethal malignancy.
- Surgical resection is the only potentially cure but because of the late presentation, only 15-20% of patients are candidates for pancreatectomy.
- The disease has a poor prognosis, even after a complete resection. Five-year survival after margin-negative (R0) pancreaticoduodenectomy is around 30% for node-negative and 10% for node-positive disease.
- Pancreatic cancer usually refers to a ductal adenocarcinoma of the pancreas (85% of all pancreatic neoplasms).
- More than 95% of malignant neoplasms of the pancreas arise from the exocrine elements.
- The most common presenting symptoms in patients with exocrine pancreatic cancer are pain, jaundice and weight loss.
- The initial presentation of pancreatic cancer varies according to tumor location. Around 60-70% of exocrine pancreatic cancers are localized to the head of the pancreas, while 20-25% of pancreatic cancers are located in the body/tail and the remainder involve the whole organ
- Compared with tumors in the body and tail of the pancreas, tumors located in the head present more often with jaundice, steatorrhea and weight loss.
- Pain is one of the most frequently reported symptoms, even with small (<2 cm) pancreatic cancers
- The pain associated with pancreatic cancer is usually insidious in onset, and has been present for 1 to 2 months at the time of presentation.
- Pain has a typical gnawing visceral quality, and is generally epigastric, radiating to the sides and/or straight through to the back.
- Pain may be intermittent and made worse by eating or lying supine.
- Pain is frequently worse at night. Lying in a curled or fetal position may improve the pain.
- Severe back pain should raise suspicion for a tumor arising in the body and tail of the pancreas.
- Rarely, pain develops very acutely, as a result of an episode of acute pancreatitis due to tumoral occlusion of the main pancreatic duct.
- Jaundice is a relatively early sign in tumors arising from the pancreatic head and pancreatic tumors that present with painless jaundice have been ascribed a relatively more favorable prognosis compared with those that present with pain and obstructive jaundice. Jaundice secondary to a tumor in the body or tail typically occurs later in the course of the disease, and may be secondary to liver metastases.
- A recent onset of diabetes mellitus may be noted.
- Unexplained superficial thrombophlebitis, which may be migratory (classic Trousseau’s syndrome) is sometimes present.
- Metastatic commonly affects the liver, peritoneum, lungs and less frequently, bone.
- A solid pancreatic lesion is uncommonly found as an incidental finding on CT scans.
