Cancer is one of the diseases affecting the elderly and can lead to loss of life years. The skin, breast, gastric, colorectal, and lung cancers are five prevalent cancers in the elderly. The present study was conducted to evaluate the incidence and burden of these cancers in the elderly.
This secondary study was conducted on available extracted data from the population-based cancer registry in Markazi province in 2019. The data of all cases older than 60 years that lived more than six months in Markazi province were extracted. Collecting information involves gathering data on cancer incidence and death rates based on age and sex groups, as well as overall mortality rates. This also includes survival rates, recovery rates for cancer patients, and disability attributed to cancer using the global burden of disease (GBD) standard table from various sources. Various data, including the latest death registration report and the latest cancer registration report for 2019 and the Iran Statistics Center, were obtained. In order to check and analyze the data, Excel and DISMOD2 software were used. In order to analyze the data, formulas for calculating the burden of diseases (DALY=YLL+YLD) were used. For the validity and reliability of the data, the method of preventing the registration of impossible codes and useless codes was used.
The incidence rate of skin, breast, gastric, colorectal, and lung cancers in elderly women was 52.87, 59.02, 67.63, 47.95, and 20.90, respectively, per 100000. DALYs of these cancers in elderly women were 63.15, 423.86, 686.37, 366.49, and 385.18, respectively. The incidence rate of skin, gastric, colorectal, and lung cancers in elderly men was 100.84, 135.80, 49.74, and 68.57, respectively per 100000. DALYs of these cancers in elderly men were 342.31, 1117.01, 337.99, and 452.41, respectively. The highest YLL and YLD were related to gastric cancer (493.31/100,000) and breast cancer (220.84/100,000).
Based on the results of this study, the incidence, mortality, and DALY of skin, breast, stomach, colorectal and lung cancers were higher in the elderly. In this study, the burden of some cancers such as breast, was lower compared to provinces such as Yazd.
癌症是影响老年人的疾病之一，可导致生命年数的损失。皮肤癌、乳腺癌、胃癌、结直肠癌和肺癌是老年人中五种常见的癌症。本研究旨在评估这些癌症在老年人中的发病率和负担。
这项二次研究是基于2019年马尔卡齐省基于人群的癌症登记处的可用提取数据进行的。提取了所有60岁以上且在马尔卡齐省居住超过6个月的病例数据。收集信息包括基于年龄和性别组收集癌症发病率和死亡率数据，以及总体死亡率。这还包括生存率、癌症患者的康复率，以及使用来自各种来源的全球疾病负担（GBD）标准表归因于癌症的残疾情况。获取了各种数据，包括2019年最新的死亡登记报告、最新的癌症登记报告以及伊朗统计中心的数据。为了检查和分析数据，使用了Excel和DISMOD2软件。为了分析数据，使用了计算疾病负担的公式（伤残调整生命年=YLL+YLD）。为了确保数据的有效性和可靠性，采用了防止登记不可能代码和无用代码的方法。
老年女性皮肤癌、乳腺癌、胃癌、结直肠癌和肺癌的发病率分别为每10万例52.87、59.02、67.63、47.95和20.90例。这些癌症在老年女性中的伤残调整生命年分别为63.15、423.86、686.37、366.49和385.18。老年男性皮肤癌、胃癌、结直肠癌和肺癌的发病率分别为每10万例100.84、135.80、49.74和68.57例。这些癌症在老年男性中的伤残调整生命年分别为342.31、1117.01、337.99和452.41。最高的YLL和YLD与胃癌（493.31/100,000）和乳腺癌（220.84/100,000）有关。
基于本研究结果，老年人皮肤癌、乳腺癌、胃癌、结直肠癌和肺癌的发病率、死亡率和伤残调整生命年较高。在本研究中，与亚兹德等省份相比，某些癌症如乳腺癌的负担较低。
