Analysis of Death Causes of In-patients with Malignant Tumors in Sichuan Cancer Hospital of China from 2002 to 2012

Objectives: To analyze underlying disease, fatality rate and the major causes of death of in-patients withmalignant tumors in Sichuan Cancer Hospital.
Methods: Clinical data of in-patients from 2002 to 2012 wereretrospectively analyzed.
Results: The top 10 tumors (82.0%of the total) of the malignant tumors of the inpatientswere lung, cervical, esophagus, breast, colorectal, nasopharynx, liver and gastric cancers, lymphomasand ovarian cancers. The overall fatality rate was 2.7% during these eleven years, 3.4% and 2.0% for maleand females, respectively with statistical significance for the difference (χ2=164.737, P<0.001). The top 10 deathcauses were lung cancer, liver cancer, colorectal cancer, esophagus cancer, gastric cancer, lymphoma, breastcancer, pancreatic cancer, ovarian cancer and nasopharynx cancer. In-patients with pancreatic cancer had thehighest fatality rate (9.6%). There were different ranks of death causes in different sex groups and age groups.
Conclusion: Prevention and control work of cancer should be enhanced not only for cancers with high incidencesuch as lung cancer, esophageal cancer but also for the cancers which have low incidence but high fatality rate,such as pancreatic cancer and gallbladder cancer, which would help to improve the survival rate and quality oflife of cancer patients in the future.
