- چکیده:
- چکیده انگلیسی: The objective of this study was to clarify how distance from place of residence to the nearest specialist cancer hospital affects the survival rates of lung cancer patients and the treatment provided by hospitals. All patients diagnosed with lung cancer in the Aomori cancer registry database for the period from 2009 to 2011 (n=3,986). The distance to hospital was measured as the straight line distance from a person’s place of residence to his or her treating hospital, and we used the Ederer II method for calculating relative survival. The information of treatments given was obtained by data extraction. We defined the hospital having respiratory medicine as Specialist hospital. All private hospital and clinic were included in General hospital and clinic. Patients attending specialist hospital were 2,548 (67.0%), and general hospital and clinic were 1,255 (33.0%). The patient who had the lowest relative survival in localized group lived

- چکیده:
- چکیده انگلیسی: Background: Together with such high-quality approaches as randomized controlled trials and large-scale cohort
studies, simulation models are often employed to evaluate the effect of cancer screening methods and decide on
their appropriateness. This study aimed to evaluate all effects of gastric cancer screening that have been assessed
using simulation models, including cost-effectiveness, mortality reduction, and early-stage detection. Methods: We
performed a systematic review using PubMed and Web of Science. We evaluated the effect of screening related to
cost, such as incremental cost-effectiveness and incremental cost-effectiveness ratios; we also separately assessed
effects other than cost, such as quality-adjusted life-years, number of deaths prevented, life-years saved, relative risk
of mortality from gastric cancer, life expectancy, and incidence reduction. The methods targeted for evaluation were
Helicobacter pylori testing or endoscopy. Results: We identified 19 studies dealing with simulation models in gastric
cancer screenings: 14 examined H. pylori screening and 7 focused on endoscopy. Among those studies, two assessed
both H. pylori and endoscopy screening. Most of the studies adopted a Markov model, and all the studies evaluated
cost-effectiveness. Of the 14 H. pylori screening studies, 13 demonstrated cost-effectiveness and 11 also showed good
results other than cost-effectiveness, such as extension of life-years and increase in early-stage detection. In three of the
five endoscopy studies, the target population was patients; all five studies obtained good results for cost-effectiveness
and four observed good results other than for cost-effectiveness. Conclusions: In this study, we showed that the H.
pylori screening test was cost-effective in terms of simulation model investigations. However, the H. pylori screening
test should not ordinarily be recommended since there is insufficient evidence that it reduces gastric cancer mortality.
In Japan, simulation modeling should be employed to plan for cancer control, and the appropriate use of simulation
models should be examined for future use.- انتشار مقاله: 22-06-1396

- چکیده انگلیسی: Background: Aomori Prefecture has experienced the highest cancer-related mortality rates since the 2000s in Japan.
In addition, income of residents in Aomori Prefecture is lower than that of a countrywide average. Aims of this study
were to examine the relationships of the incidence and mortality rates of common cancers (stomach, colorectal, liver,
lung, breast, cervical, and prostate) with the income levels of residential income area and clarify the factors contributing
to the high mortality rates in Aomori prefecture.Methods: We included data on all patients diagnosed with stomach,
colorectal, liver, lung, breast, cervical, or prostate cancer in the Aomori cancer registry database between 2010 and
2012. Age-standardized incidence rates and incidence rate ratios were calculated. Risk of cancer mortality related to
economic disparities was determined via multivariable Cox regression analysis and adjusted for age, sex, and stage at
diagnosis in the multivariable model. Results: We identified 21,240 eligible cancer patients. There were no differences
in AIRs and IRRs among patients with stomach, colorectal, or lung cancer according to income. Contrarily, AIRs and
IRRs were higher in higher-income areas than in lower-income areas among patients with breast, cervical, or prostate
cancer. There were no significant differences in HRs according to income for any cancer type. Conclusions:Patients
with higher income were diagnosed with early-stage disease more frequently, and they had higher AIRs for breast,
cervical, and prostate cancers than those with middle and low incomes. However, there were no significant differences
in hazard ratios.- انتشار مقاله: 07-02-1397
