■在韩国,从2001年到2021年,癌症发病率增加了56.5%。然而,与2001年至2005年相比,2017年至2021年的5年癌症生存率增加了17.9%。癌症生存率随着社会经济地位的降低而下降,不同癌症类型之间的存活率存在差异。分析癌症患者生存的社会经济模式可以帮助识别高危人群,并确保他们从干预措施中受益。
■本研究的目的是分析被诊断为六种类型胃癌的患者的生存率差异,结直肠,肝脏,乳房,子宫颈,和肺癌-基于韩国全国数据的社会经济地位。
■这项研究使用与国家健康信息数据库链接的韩国中央癌症登记数据库,对2014年至2018年12月31日期间诊断为癌症的患者进行随访。生成了按收入状况分层的Kaplan-Meier曲线,并对每种癌症类型进行对数秩检验,以评估统计学显著性.使用Cox比例风险回归模型计算任何原因的总生存期的95%CI的风险比。
■六种不同类型癌症的存活率如下:胃癌,69.6%(96,404/138,462);结直肠癌,66.6%(83,406/125,156);肝癌,33.7%(23,860/70,712);肺癌,30.4%(33,203/109,116);乳腺癌,91.5%(90,730/99,159);和宫颈癌,78%(12,930/16,580)。在将医疗援助组与最高收入组进行比较时,胃癌的风险比为1.72(95%CI1.66-1.79),结直肠癌1.60(95%CI1.54-1.56),肝癌1.51(95%CI1.45-1.56),肺癌为1.56(95%CI1.51-1.59),2.19(95%CI2.01-2.38)用于乳腺癌,宫颈癌为1.65(95%CI1.46-1.87)。较高的剥夺指数和晚期诊断阶段与死亡风险增加相关。
■社会经济地位在几种癌症类型中显著调节癌症生存率的差异。这种效应在不太致命的癌症如乳腺癌中尤其明显。因此,考虑到癌症的类型和社会经济因素,社会和医疗干预措施,如早期癌症检测和适当的治疗对于弱势群体是必要的。
UNASSIGNED: In South Korea, the cancer incidence rate has increased by 56.5% from 2001 to 2021. Nevertheless, the 5-year cancer survival rate from 2017 to 2021 increased by 17.9% compared with that from 2001 to 2005. Cancer survival rates tend to decline with lower socioeconomic status, and variations exist in the survival rates among different cancer types. Analyzing socioeconomic patterns in the survival of patients with cancer can help identify high-risk groups and ensure that they benefit from interventions.
UNASSIGNED: The aim of this study was to analyze differences in survival rates among patients diagnosed with six types of cancer-stomach, colorectal, liver, breast, cervical, and lung cancers-based on socioeconomic status using Korean nationwide data.
UNASSIGNED: This study used the Korea Central Cancer Registry database linked to the National Health Information Database to follow up with patients diagnosed with cancer between 2014 and 2018 until December 31, 2021. Kaplan-Meier curves stratified by income status were generated, and log-rank tests were conducted for each cancer type to assess statistical significance. Hazard ratios with 95% CIs for any cause of overall survival were calculated using Cox proportional hazards regression models with the time since diagnosis.
UNASSIGNED: The survival rates for the six different types of cancer were as follows: stomach cancer, 69.6% (96,404/138,462); colorectal cancer, 66.6% (83,406/125,156); liver cancer, 33.7% (23,860/70,712); lung cancer, 30.4% (33,203/109,116); breast cancer, 91.5% (90,730/99,159); and cervical cancer, 78% (12,930/16,580). When comparing the medical aid group to the highest income group, the hazard ratios were 1.72 (95% CI 1.66-1.79) for stomach cancer, 1.60 (95% CI 1.54-1.56) for colorectal cancer, 1.51 (95% CI 1.45-1.56) for liver cancer, 1.56 (95% CI 1.51-1.59) for lung cancer, 2.19 (95% CI 2.01-2.38) for breast cancer, and 1.65 (95% CI 1.46-1.87) for cervical cancer. A higher deprivation index and advanced diagnostic stage were associated with an increased risk of mortality.
UNASSIGNED: Socioeconomic status significantly mediates disparities in cancer survival in several cancer types. This effect is particularly pronounced in less fatal cancers such as breast cancer. Therefore, considering the type of cancer and socioeconomic factors, social and medical interventions such as early cancer detection and appropriate treatment are necessary for vulnerable populations.
