Objective  To analyze the data of cancer inpatients in our hospital from 2012 to 2016, so as to help staff understanding the distribution characteristics of cancers and allocating medical resources.

  Methods  Using ICD-10 code and SQL statement, the data of cancer inpatient were extracted from HIS (Hospital Information System) and analyzed.

  Results  In the past 5 years, there were 243 200 cancer inpatient admitted to our hospital, accounting for 32.54% of the total inpatient volume. Among them, male accounted for 57.99% and female accounted for 42.01%. Ten most common cancer in male were lung cancer (18.50%), liver cancer (13.21%), gastric cancer (11.50%), colorectal cancer (11.40%), lymphoma (5.43%), otolaryngologic cancer (4.56%), leukemia (4.52%), esophageal cancer (3.84%), renal cancer (2.63%) and pancreatic cancer (2.54%), while ten most common cancer in female were breast cancer (20.08%), lung cancer (12.63%), colorectal cancer (8.79%), ovarian cancer (7.06%), cervical cancer (5.56%), gastric cancer (4.99%), lymphoma (4.53%), thyroid cancer (4.35%), leukemia (3.84%) and liver cancer (3.76%). The relationship between age and cancer incidence demonstrated an inverted U-shape, with patient number peaked in 50-69 years, and declined in both 0-39 years and > 70 years groups. Currently, chemotherapy (57.66%) and surgery (24.49%) were still the main treatment for cancer.

  Conclusion  The number of cancer inpatients in our hospital is increasing year by year, and the incidence of cancer is higher in male than that in female. The most common cancer types vary by gender and age. Similarities and differences in data sources and statistical results lead to the differences when compared with relevant cancer data reports at home and abroad.
