Although rates of detection adenomatous lesions (tumors or polyps) and cecal intubation are recommended for use as quality indicators screening colonoscopy, these measurements have not been validated, their importance remains uncertain.We used a multivariate Cox proportional-hazards regression model to evaluate the influence colonoscopy on risk interval cancer. Data were collected from 186 endoscopists who involved in colonoscopy-based colorectal-cancer program involving 45,026 subjects....

The purpose of this paper is to offer the most important epidemiological indicators malignant neoplasms in Poland for year 2019. In 2019, Polish National Cancer Registry received information on almost 171.2 thousand new cancer cases and 100.3 deaths. common male cancers were prostate (20.6%), lung (16.1%), colon (6.8%), bladder (6.4%), rectal (4.2%) cancers. Age-standardized incidence rates at 118 per 100,000 prostate, 89 lung, 40 colon, 38 bladder, 23 rectum. prevalent female encompassed...

Importance Patients of physicians with higher adenoma detection rates (ADRs) during colonoscopy have lower colorectal cancer (CRC) risk after screening (ie, postcolonoscopy CRC). Among an ADR above the recommended threshold, it is unknown whether improving associated a incidence CRC in their patients. Objective To determine association improved range values at baseline among Design, Setting, and Participants A total 789 Polish Colonoscopy Screening Program were studied between 2000 2017,...

A significant proportion of upper gastrointestinal cancers (UGICs) remain undetected during esophagogastroduodenoscopy (EGD). We investigated the characteristics and risk factors UGICs missed endoscopy.In this nationwide registry-based study, we analyzed two large Polish datasets (National Health Fund National Cancer Registry) to identify individuals who underwent EGD were subsequently diagnosed with UGIC. Cancers < 6 months after defined as "prevalent" those within ≥ 6- 36 "missed."...

Introduction. Cancers are a real global health problem. Europe accounts for 1/10 of the world's population, but ¼ all cancer cases occurs in this region. Poland is group countries where mortality highest [1]. The aim article to present summary epidemiological indicators malignant neoplasms 2023. Material and methods. This report presents observed morbidity data 2010–2021 also estimated values two years ahead (2022–2023). Data aggregation was carried out according sex, age, site, or...

Abstract Risk factors of cervical cancer (CC) development are well investigated, however, those influencing the risk a potential false negative cytology preceding diagnosis an invasive CC not. We have aimed to explore these according data from Organised Cervical Cancer Screening Programme (OCCSP) in Poland. A total 2.36 million Pap tests sampled 2010–2012 within OCCSP were merged with Polish National Registry identify cases after abnormal and normal 3 years screening. Of 1460 CCs, 1025...

It is well established that older patients with cancer have a significantly higher risk of suicide. However, comprehensive understanding the factors lacking. In this study, we aimed to identify groups at an increased suicide among aged ≥75 years previous diagnosis.All Polish individuals diagnosed age between 1 January 2009 and 31 December 2019 were included in study. Standardized mortality ratios (SMRs) 95 % confidence intervals (CIs) calculated.A total 410,440 (211,730 men 198,710 women)...

Abstract Available epidemiological reports on follicular lymphoma (FL) often highlight a significant discrepancy between its high and low incidence rates in Western Eastern Europe, respectively. The reasons behind that difference are not fully understood, but underreporting is typically presumed as one of the main factors. This study aimed to assess FL epidemiology Poland based 2000–2014 data from Polish National Cancer Registry, which has 100% population coverage over 90% completeness...

Methods deployed cohort all cases primary neoplasms diagnosed between the 1st January 2009 31st December 2019 individuals aged 15–39 years registered in Polish National Cancer Registry. To assess comparison general AYA population, we calculated sex–age–year standardized mortality ratios (SMR) 95% confidence intervals...
