Analysis on the survival situation of pancreatic cancer patients in Shanghai from 2002 to 2006

ObjectiveTo analyze survival situation of pancreatic cancer patients in Shanghai from 2002 to 2006.

MethodsBased on the cancer registration data collected by Shanghai Cancer Registry for the pancreatic cancer patients in Shanghai from 2002 to 2006 as well as the reports of the follow-up visits thereof, the Life Table and the Ederer Ⅱ method were used to calculate the observed survival (OS) and the relative survival (RS) thereof and to analyze the factors influencing survival rates thereof.

ResultsThe 5-year OS and RS of pancreatic cancer patients in Shanghai from 2002 to 2006 were 6.63% and 10.11%, respectively. The 5-year OS varied with each age group of pancreatic cancer patients. With the age increase of pancreatic cancer patients, the survival rate thereof gradually decreased. The survival rates of pancreatic cancer patients diagnosed to be at Phase Ⅰ and Phase Ⅱ were higher than those thereof diagnosed to be at Phase Ⅲ and Phase Ⅳ. The survival rate of the patients for whom pancreatic cancer was sited at body of pancreas was higher than that of the patients for whom pancreatic cancer was sited elsewhere. For the survival rate thereof, there were no significant differences between different genders, or between the urban and the suburbs/outskirts. In the past 30 years, the survival rates for both male and female patients with pancreatic cancer in the urban area of Shanghai increased to a certain extent.

ConclusionThe survival rate of pancreatic cancer patients in Shanghai increases on a yearly basis. Age(of patients), phasing(of pancreatic cancer), subsite(location)(of pancreatic cancer), etc. will all influence the survival rates of pancreatic cancer patients.
