Disease burden of lung cancer in Jinchang cohort / 中华流行病学杂志

<p><b>OBJECTIVE</b>To understand the current status of lung cancer disease burden in Jinchang cohort.</p><p><b>METHODS</b>In this historical cohort study, the mortality data of the lung cancer from 2001 to 2013 and medical records of the lung cancer cases from 2001 to 2010 in Jinchang cohort were used, analyze mortality, direct economic burden, potential years of life lost (PYLL) and working PYLL (WPYLL) associated with lung cancer.</p><p><b>RESULTS</b>A total of 434 lung cancer deaths occurred in Jinchang cohort from 2001 to 2013. The crude mortality rate of lung cancer was 78.06 per 100,000 from 2001 to 2013, with the increasing rate of 4.77%. The mortality rate of lung cancer in males and females were about 108.90 per 100,000 and 26.08 per 100,000 with the increasing rate of 4.24% and 6.91%, respectively. During the thirteen years, the PYLL and average PYLL (APYLL) of lung cancer were 3 721.71 person-years and 8.58 years. The APYLL of lung cancer in females (15.94 years) was higher than that in males (7.87 years). The WPYLL and the average WPYLL (AWPYLL) of lung cancer were 1161.00 person-years and 2.68 years, respectively. The AWPYLL of lung cancer was also higher in females than in males. The direct economic burden of lung cancer from 2001 to 2010 in Jinchang cohort was 6309.39 Yuan per case with no increased trend.</p><p><b>CONCLUSION</b>Lung cancer is the main health problem in Jinchang cohort, causing heavy disease burden.</p>

Disease burden of liver cancer in Jinchang cohort / 中华流行病学杂志

<p><b>OBJECTIVE</b>To understand the current status of the disease burden of liver cancer in Jinchang cohort.</p><p><b>METHODS</b>All the liver cancer death data from 2001 to 2013 and medical records of liver cancer cases from 2001 to 2010 in Jinchang cohort were collected for the analyses of the mortality, standardized mortality, potential years of life lost (PYLL) and working PYLL (WPYLL) associated with liver cancer. Spearman correlation and the average growth rate were used to analyze the trends.</p><p><b>RESULTS</b>A total of 207 liver cancer deaths occurred in Jinchang cohort from 2001 to 2013, accounting for 16.68% of total cancer deaths. There were 259 liver cancer inpatients, accounting for 6.79% of the total cancer cases inpatients, in which 83 died (32.05%). Liver cancer death mainly occurred in males, accounting for 88.89%, and the liver cancer deaths in females accounted for 11.11%. The standardized mortality rate was 42.32/100,000 in males and 15.31/100,000 in females. The growth rate of liver cancer mortality was 5.62% from 2001 to 2013. Liver cancer deaths mainly occurred in age groups 60-69 years (26.57%) and 50-59 years (24.15%). The PYLL was 2906.76 person-years, the average PYLL was 14.04 years. The WPYLL was 1477.00 person-years and the average WPYLL was 7.14 years. The direct economic burden of liver cancer was 6270.78 Yuan per person, 301.75 Yuan per day. The average stay of hospitalization was 21.32 days.</p><p><b>CONCLUSION</b>The mortality rate of liver cancer is increasing and the disease burden is still heavy.</p>

Disease burden of colorectal cancer in Jinchang cohort / 中华流行病学杂志

<p><b>OBJECTIVE</b>To evaluate the disease burden of colorectal cancer in Jinchang cohort, and provide evidence for preventing colorectal cancer and reducing the disease burden of colorectal cancer in the cohort.</p><p><b>METHODS</b>The colorectal cancer mortality data from 2001 to 2013 and the medical records of colorectal cancer patients from 2001 to 2010 were collected for this retrospective cohort study. The colorectal cancer disease burden was described by using mortality rate, standardized mortality rate, medical expenditure, potential years of life lost (PYLL), average potential years of life lost (APYLL), working potential years of life lost (WPYLL), and average working potential years of life lost (AWPYLL). The development trend in disease burden of colorectal cancer was analyzed by using Spearman correlation and the average growth rate.</p><p><b>RESULTS</b>The crude mortality rate of colorectal cancer from 2001 to 2013 was 9.53/100,000 with the average annual growth rate of 12.89%. The PYLL, APYLL, WPYLL and AWPYLL of colorectal cancer were 485.00 person-years, 9.15 years, 253.00 person-years, and 4.77 years, respectively. The direct medical expenditure due to colorectal cancer was 7064.38 Yuan per case and 408.43 Yuan per day. There was no increasing trend in the direct medical expenditure due to colorectal cancer.</p><p><b>CONCLUSION</b>Colorectal cancer mortolity rate was on the rise and it caused heavy disease burden in Jinchang cohort.</p>
