The purpose of this paper is to offer the most important epidemiological indicators of malignant neoplasms in Poland for the year 2019. In 2019, the Polish National Cancer Registry received information on almost 171.2 thousand new cancer cases and 100.3 thousand cancer deaths. The most common male cancers were prostate (20.6%), lung (16.1%), colon...

The aim of this study was to estimate the survival of Polish Burkitt lymphoma/leukemia (BL) patients diagnosed between 1999 and 2017, considering multiple covariates and periods, to reflect changes in BL treatment. We identified all BL patients registered in the Polish National Cancer Registry in 1999–2017. Observed survival (OS) was evaluated depl...
Article
Background The purpose of this study was to estimate the high incidence cancers survival in Poland between 2000 and 2018, with the following aim to monitor the national polish cancer control program 2020–2030 effectiveness. We calculated survival in cancer of lung, breast, prostate, colon, rectum, ovarian, cervical cancers, and skin melanoma. Meth...

Background & Aims The proportion of colonoscopies with at least one adenoma (adenoma detection rate, ADR) is inversely associated with colorectal cancer (CRC) risk and death. The aim of this study was to examine such associations exist for colonoscopy quality measures other than the ADR. Methods We used data from the Polish Colorectal Cancer Scree...

Background: A significant proportion of upper gastrointestinal cancers (UGICs) remain undetected during esophagogastroduodenoscopy (EGD). We investigated the characteristics and risk factors of UGICs missed during endoscopy. Methods: In this nationwide registry-based study, we analyzed two large Polish datasets (National Health Fund and National...

Risk factors of cervical cancer (CC) development are well investigated, however, those influencing the risk of a potential false negative cytology preceding diagnosis of an invasive CC are not. We have aimed to explore these factors according to the data from Organised Cervical Cancer Screening Programme (OCCSP) in Poland. A total of 2.36 million o...
Article
We have aimed to study reasons for reporting false-negative cytology results preceding diagnosis of interval cervical cancers (CC) in Poland. Data on all Pap smears collected in the organised screening in 2010-2015 were retrieved from the electronic database and linked with Polish National Cancer Registry (PNCR) data. False-negative results were de...

Available epidemiological reports on follicular lymphoma (FL) often highlight a significant discrepancy between its high and low incidence rates in Western and 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...
Article
Background: Current guidelines recommend a 10-year interval between screening colonoscopies, but evidence is limited. Objective: To assess the long-term risk for colorectal cancer (CRC) and death from CRC after a high- and low-quality single negative screening colonoscopy. Design: Observational study. Setting: Polish Colonoscopy Screening Pr...
Article
Full-text available
Background & aims: Recommendation of surveillance colonoscopy should be based on risk of colorectal cancer and death after adenoma removal. We aimed to develop risk classification system based on colorectal cancer incidence and mortality following adenoma removal. Methods: We performed a multicenter population-based cohort study of 236,089 indiv...
Article
Population screening programs should be efficient and cost-effective. Cervical cancer screening program was implemented in Poland in 2006 and so far it did not achieve the main goal of the screening, which is to reduce the mortality rate of cervical cancer in the entire female population. The main reason of this are: poor organization that causes l...
Article
Introduction The aim of this study is to assess the changes in lung cancer mortality in Poland, being one of the highest in Europe, in relation to changes in smoking prevalence by the level of education. Methods Data come from the Central Statistical Office. Data on education are collected during the census surveys and covers years 1994-2012. The...
Article
Introduction. Survival rates are a tool that allows evaluation of healthcare quality and cancer treatment efficiency. The main aim of this article is to present tendencies in curability of Polish patients diagnosed between 1999-2010 and followed up until the end of 2015. Materials and methods. Survival analysis was performed using data from the Pol...

In 2015, the second cycle of the CONCORD programme established global surveillance of cancer survival as a metric of the effectiveness of health systems and to inform global policy on cancer control. CONCORD-3 updates the worldwide surveillance of cancer survival to 2014. Methods CONCORD-3 includes individual records for 37·5 million patients diagn...

Gathering cancer staging data is an important task in many cancer registers. Cancer staging is crucial for epidemiological analyses involving effectiveness of primary prevention programs, screening methods, and oncological treatment outcomes. In the Greater Poland Cancer Registry, the main source of information on cancer staging is the cancer notif...
Article
Aside from existing opportunistic screening, an organised screening programme (OSP) for cervical cancer (CC) was implemented in 2006/2007 in Poland. We applied joinpoint regression and age-period-cohort model to look for the impact of the OSP on CC incidence/mortality trends. Decline of age-standardised incidence rates (ASIRs) in the screening-age...

Background Cancer is a major cause of death in children worldwide, and the recorded incidence tends to increase with time. Internationally comparable data on childhood cancer incidence in the past two decades are scarce. This study aimed to provide internationally comparable local data on the incidence of childhood cancer to promote research of cau...

Background: Global inequalities in access to health care are reflected in differences in cancer survival. The CONCORD programme was designed to assess worldwide differences and trends in population-based cancer survival. In this population-based study, we aimed to estimate survival inequalities globally for several subtypes of childhood leukaemia....

Przewlekła białaczka limfocytowa (CLL) jest nowotworem, który sprawia pewne trudności w opisie epidemiologicznym ze względu na statystyczne ujęcie nowotworów krwi w X Rewizji Międzynarodowej Klasyfikacji Chorób i Problemów Zdrowotnych. W Polsce w 2013 roku CLL stanowiła 1,3% wszystkich zachorowań na nowotwory w populacji mężczyzn i 1% u kobiet (odp...

Barrett's Oesophagus (BO) is a complication of chronic gastro-oesophageal reflux disease (GORD) and is a major risk factor for oesophageal adenocarcinoma. Current guidelines are based on data showing a 0.5% annual malignancy progression rate. The Polish Barrett's Oesophagus Registry (POBOR) was established to characterize Polish patients with BO an...

Over the last century, lung cancer from the rarest of diseases became the biggest cancer killer of men worldwide and in some parts of the world also of women (North America, East Asia, Northern Europe, Australia and New Zealand). In 2012 over 1.6 million of people died due to lung cancer. The cause-effect relationship between tobacco smoking and lu...

Worldwide data for cancer survival are scarce. We aimed to initiate worldwide surveillance of cancer survival by central analysis of population-based registry data, as a metric of the effectiveness of health systems, and to inform global policy on cancer control. Individual tumour records were submitted by 279 population-based cancer registries in...

The aging population and the increasing incidence of hematological malignancies is a challenge for the health care system in Poland. New medical technologies offer opportunities for patients above 65 years of age. Their use, however, requires careful research and confirm their usefulness in the context of current therapeutic guidelines. The require...

Although rates of detection of adenomatous lesions (tumors or polyps) and cecal intubation are recommended for use as quality indicators for screening colonoscopy, these measurements have not been validated, and their importance remains uncertain. We used a multivariate Cox proportional-hazards regression model to evaluate the influence of quality...
