Answer

Pancreatic carcinoma is unfortunately usually a fatal disease. The collective median survival time for all patients is 4-6 months.

The relative 1-year survival rate for patients with pancreatic cancer is only 28%, and the overall 5-year survival rate is 9%, having increased from the 3% rate as calculated between 1975 and 1977. [11] (However, patients with neuroendocrine and cystic neoplasms of the pancreas, such as mucinous cystadenocarcinomas or intraductal papillary mucinous neoplasms [IPMN], have much better survival rates than do patients with pancreatic adenocarcinoma.)

A 5-year survival in pancreatic cancer is no guarantee of cure; patients who survive for 5 years after successful surgery may still die of recurrent disease years after the 5-year survival point. The occasional patient with metastatic disease or locally advanced disease who survives beyond 2-3 years may die of complications of local spread, such as bleeding esophageal varices.

In patients able to undergo a successful curative resection (about 20% of patients), median survival time ranges from 12-19 months, and the 5-year survival rate is 15-20%. The best predictors of long-term survival after surgery are a tumor diameter of less than 3 cm, no nodal involvement, negative resection margins, and diploid tumor deoxyribonucleic acid (DNA) content.

The median survival for patients who undergo successful resection (only 20% of patients) is approximately 12-19 months, with a 5-year survival rate of 15-20%.

Tingle et al reported that in patients with unresectable pancreatic ductal adenocarcinoma, the combination of the neutrophil-albumin ratio (NAR) and the Ca19-9 level allows stratification into three groups with significantly different overall survival, as follows [42] :

  • NAR ≤ 0.13 and Ca19-9 ≤ 770 U/mL - Median survival 20.5 months
  • NAR > 0.13 or Ca19-9 >770 - Median survival 9.7 months
  • NAR > 0.13 and Ca19-9 > 770 - Median survival 4.1 months
