Estimation Of Variance

Purpose The study sought to determine if mammography quality is associated with the false positive (FP) rate in the Quebec breast cancer screening program in 2004 and 2005. Methods Mammography quality of a random sample of screen-film mammograms was evaluated by an expert radiologist following the criteria of the Canadian Association of Radiologists. For each screening examination, scores ranging from 1 (poor quality) to 5 (excellent quality) were attributed for positioning, compression, contrast, exposure level, sharpness, and artifacts. A final overall quality score (lower or higher) was also given. Poisson regression models with robust estimation of variance and adjusted for potential confounding factors were used to assess associations of mammography quality with the FP rate. Results Among 1,209 women without cancer, there were 104 (8.6%) FPs. Lower overall mammography quality is associated with an increase in the FP rate (risk ratio [RR], 1.4; 95% confidence interval [CI], 1.0-2.1; P = .07) but this increase was not statistically significant. Artifacts were associated with an increase in the FP rate (RR, 2.1; 95% CI, 1.3-3.3; P = .01) whereas lower quality of exposure level was related to a reduction of the FP rate (RR, 0.4; 95% CI, 0.1-1.0; P = .01). Lower quality scores for all other quality attributes were related to a nonstatistically significant increase in the FP rate of 10%-30%. Conclusions Artifacts can have a substantial effect on the FP rate. The effect of overall mammography quality on the FP rate may also be substantial and needs to be clarified.

Célkitűzés: Az országos kiterjedésű, szervezett emlőszűrési program 2002 januárjában indult el Magyarországon a 45–65 év közötti nők számára 2 éves szűrési intervallummal. A dolgozat célja a szervezett emlőszűrési program részvételi mutatóinak meghatározása, beleértve a szűrési és diagnosztikus célú képalkotó emlőfelvételek gyakoriságának elemzését. Adatok és módszerek: Az elemzésben szereplő adatok az Országos Egészségbiztosítási Pénztár finanszírozási adatbázisából származnak, és a 2000–2005 közötti 6 évet ölelik fel. A 45–65 éves nők körében meghatározták azok arányát, akik a szervezett szűrést megelőző két évben (2000–2001), illetve a program első két ciklusában (2002–2003, 2004–2005) akár szűrési, akár diagnosztikai célú képalkotó emlővizsgálaton vettek részt. Eredmények: A szűrési célú képalkotó emlőfelvételen részt vettek aránya (átszűrtség) a 2000–2001-es 7,4%-ról a 2002–2003-as, illetve 2004–2005-ös szervezett emlőszűrési ciklusban 34,0, illetve 29,5%-ra emelkedett. A diagnosztikus célú képalkotó emlőfelvételen részt vettek aránya (átvizsgáltság) pedig ugyanezen időszakokban 19,8%-ról 22,1 (2002–2003), illetve 23,2%-ra (2004–2005) emelkedett. Az országos lefedettség (átszűrtség + átvizsgáltság) ennek megfelelően a szervezett szűrés hatására 26,2%-ról (2000–2001) 53,5%-ra (2002–2003), illetve 50,8%-ra (2004–2005) nőtt a vizsgált kétéves ciklusban a 45–65 év közötti nők esetében. Következtetés: A magyar emlőszűrési program kezdeti részvételi arányai 2004–2005-ben kissé csökkentek; az emlőrák miatti halálozás érdemi csökkentéséhez ennek emelése szükséges.

Abstract Background Breast cancer remains one of the leading causes of death in women over the age of 40 years. Breast cancer screening is used to identify women with asymptomatic cancer with the goal of enabling women to undergo less invasive treatments that lead to better outcomes, ideally at earlier stages and before the cancer progresses. Mammography is the best-studied breast cancer screening modality and the only recommended imaging tool for screening the general population of women. Objective to correlate the relation between ACR density of breast and breast cancer in screening program. Patients and Methods Our study included 40 women of breast cancer were depicted radiologically and histo-pathologically diagnosed after outreaching for screening by Digital Mammography by the Egyptian National Breast Cancer Screening Program in Ain Shams University Hospitals at period from January 2018 to October 2019.Their data were collected from the medical records of the program. Their age ranged between 40 and 65 years. Results According to the BI-RADS 5th edition 2013, cases were classified into four classes as follows: 6 were ACR-A (15.0%), 21 were ACR-B (52.5%), 12 were ACR-C (30.0%) and 1 were ACR-D (2.5%), So according to our study results dense breast shouldn’t be considered as a risk factor for breast cancer as we observed that the percentage of breast cancer in our study increases the most with average breast density ACR class B then increases with ACR class C and A respectively. Conclusion dense breast is not a risk factor for breast cancer, so further researches are needed to study the relationship between breast density and breast cancer in Egyptian population, to elucidate the role of breast density estimation in prediction of breast cancer considering the genotypical and phenotypical differences of the Egyptian population.
