Abstract Background Individual country- and cancer site-specific studies suggest that the age-adjusted incidence of many common cancers has increased in European populations over the past two ...decades. To quantify the extent of these trends and the recent burden of cancer, here we present a comprehensive overview of trends in population-based incidence of the five common cancers across Europe derived from a new web-based portal of the European cancer registries. Methods Data on incidence for cancers of the colon and rectum, prostate, breast, corpus uteri and stomach diagnosed from 1988 to 2008 were obtained from the European Cancer Observatory for cancer registries from 26 countries. Annual age-standardised incidence rates and average annual percentage changes were calculated. Results Incidence of four common cancers in eastern and central European countries (prostate, postmenopausal breast, corpus uteri and colorectum) started to approach levels in northern and western Europe, where rates were already high in the past but levelled off in some countries in recent years. Decreases in stomach cancer incidence were seen in all countries. Discussion Increasing trends in incidence of the most common cancers, except stomach cancer, are bad news to public health but can largely be explained by well-known changes in society in the past decades. Thus, current and future efforts in primary cancer prevention should not only remain focussed on the further reduction of smoking but engage in the long-term efforts to retain healthy lifestyles, especially avoiding excess weight through balanced diets and regular physical exercise.
Data curation for a hospital-based cancer registry heavily relies on the labor-intensive manual abstraction process by cancer registrars to identify cancer-related information from free-text ...electronic health records. To streamline this process, a natural language processing system incorporating a hybrid of deep learning-based and rule-based approaches for identifying lung cancer registry-related concepts, along with a symbolic expert system that generates registry coding based on weighted rules, was developed. The system is integrated with the hospital information system at a medical center to provide cancer registrars with a patient journey visualization platform. The embedded system offers a comprehensive view of patient reports annotated with significant registry concepts to facilitate the manual coding process and elevate overall quality. Extensive evaluations, including comparisons with state-of-the-art methods, were conducted using a lung cancer dataset comprising 1428 patients from the medical center. The experimental results illustrate the effectiveness of the developed system, consistently achieving F1-scores of 0.85 and 1.00 across 30 coding items. Registrar feedback highlights the system’s reliability as a tool for assisting and auditing the abstraction. By presenting key registry items along the timeline of a patient’s reports with accurate code predictions, the system improves the quality of registrar outcomes and reduces the labor resources and time required for data abstraction. Our study highlights advancements in cancer registry coding practices, demonstrating that the proposed hybrid weighted neural-symbolic cancer registry system is reliable and efficient for assisting cancer registrars in the coding workflow and contributing to clinical outcomes.

Purpose
To describe our experience upon developing and implementing a hospital-based cancer registry (HBCR) in a quaternary-level of care private non-profit academic medical center in Cali, Colombia.
...Methods
HBCRs capture, in a given institution, every single patient with a confirmed malignancy. In this study, all cases evaluated between 2014 and 2018 were included in the HBCR. In compliance with the International Agency for Research on Cancer recommendations, cases were classified as analytic or non-analytic. Data derived from an exhaustive selection of patients was stored in a computing platform owned by the institution, meeting the 2016 Facility Oncology Registry Data Standards recommendations. Quality control was performed by evaluating comparability, timeliness, validity, and completeness
.
Results
A total of 24,405 new cases were registered between 2014 and 2018, from which 4253 (17.4%) died. Among all cases, based on the anatomic location, most common malignancies were breast (
n
= 1554), thyroid (
n
= 1346), hematolymphoid (
n
= 1251), prostatic (
n
= 805), and colorectal (
n
= 624). The behavior of the new cases was consistent with an incremental trend.
Conclusion
Upon implementing the HBCR, major challenges were identified (i.e., a precise definition of cases, the development of processes for capturing new cases, a standardized data collection strategy, and carrying-out an appropriate patient follow-up). Based on our experience, the success of an HBCR largely relies on the interest from the institution, the engagement of stakeholders and financial support, that is, it depends on the adequate access over time to funding, technological, and staffing resources.
The Punjab Cancer Registry's catchment area includes the districts of Faisalabad and Nankana Sahib. It is an observational and descriptive study that covers the 3 years from 2017 to 2019, evaluating ...the distribution of cancer in these two districts.
Data on incident cancer cases diagnosed between 2017 and 2019 among residents of Faisalabad and Nankana Sahib in Pakistan, reported by the participating centres of the Registry, were reviewed retrospectively. Figures and proportions for adults, children and adolescents were computed.
During 2017 and 2019, 5678 cases were reported from Faisalabad and 390 from Nankana Sahib, with over 50% seen in females. In both districts combined, among adult females, cancers of the breast, reproductive system, and hepatobiliary system were commonly diagnosed, while cancer of the lip/oral cavity/pharynx, hepatobiliary system and non-Hodgkin lymphoma were the leading diagnoses among adult males. In children and young adults (0-19 years), acute lymphoblastic leukaemia, Hodgkin lymphoma and non-Hodgkin lymphoma were the most common diagnoses.
The cancer distribution reported from Faisalabad and Nankana Sahib is of utmost importance. However, the underreporting of cancer cases cannot be ruled out. More input from the collaborators is needed to ensure the completeness of cancer surveillance in the region.
Breast implant-associated anaplastic large cell lymphoma (ALCL) has been rapidly rising in the US and around the world, leading to a mandated “black-box” label on all silicone- and saline-filled ...implants by the Food and Drug Administration (FDA). Because regulatory decisions in the US and around the world have been influenced primarily by risk estimates derived from cancer registries, it is important to determine their validity in identifying cases of ALCL.
We reviewed all cases of ALCL submitted to the New York State Cancer Registry from a large comprehensive cancer center in New York City from 2007 to 2019. To determine the possibility of misdiagnosis or under-diagnosis of ALCL cases reported to cancer registries, we accessed the sensitivity and specificity of the ICD-O-3 codes 9714 (ALCL) and 9702 (Mature T-cell lymphoma, not otherwise specified T-NOS) to identify pathologically-proven ALCL.
We reviewed 2286,164 pathology reports from 47,466 unique patients with primary cancers. Twenty-eight cases of histologically-proven ALCL were identified. The sensitivity and specificity of the ICD-O-3 code 9714 (ALCL) were 82% and 100%, respectively. The sensitivity of the combined codes 9714/9702 (ALCL/T-NOS) was 96% and the specificity was 44%.
Previous epidemiological studies that influenced regulatory decisions by the FDA may have systematically underestimated the risk of ALCL by at least 20%. We encourage updated global risk estimates of breast ALCL using methods that ensure adequate case ascertainment.
Background
Breast cancer is the most commonly diagnosed cancer and leading cause of cancer death among women worldwide but has patterns and trends which vary in different countries. This study aimed ...to evaluate the global patterns of breast cancer incidence and mortality and analyze its temporal trends for breast cancer prevention and control.
Methods
Breast cancer incidence and mortality data in 2020 were obtained from the GLOBOCAN online database. Continued data from the Cancer Incidence in Five Continents Time Trends, the International Agency for Research on cancer mortality and China National Central Cancer Registry were used to analyze the time trends from 2000 to 2015 through Joinpoint regression, and annual average percent changes of breast cancer incidence and mortality were calculated. Association between Human Development Index and breast cancer incidence and mortality were estimated by linear regression.
Results
There were approximately 2.3 million new breast cancer cases and 685,000 breast cancer deaths worldwide in 2020. Its incidence and mortality varied among countries, with the age‐standardized incidence ranging from the highest of 112.3 per 100,000 population in Belgium to the lowest of 35.8 per 100,000 population in Iran, and the age‐standardized mortality from the highest of 41.0 per 100,000 population in Fiji to the lowest of 6.4 per 100,000 population in South Korea. The peak age of breast cancer in some Asian and African countries were over 10 years earlier than in European or American countries. As for the trends of breast cancer, the age‐standardized incidence rates significantly increased in China and South Korea but decreased in the United States of America (USA) during 2000‐2012. Meanwhile, the age‐standardized mortality rates significantly increased in China and South Korea but decreased in the United Kingdom, the USA, and Australia during 2000 and 2015.
Conclusions
The global burden of breast cancer is rising fast and varies greatly among countries. The incidence and mortality rates of breast cancer increased rapidly in China and South Korea but decreased in the USA. Increased health awareness, effective prevention strategies, and improved access to medical treatment are extremely important to curb the snowballing breast cancer burden, especially in the most affected countries.
The Japan Cancer Surveillance Research Group aimed to estimate the cancer incidence in Japan in 2009 based on data collected from 32 of 37 population-based cancer registries, as part of the ...Monitoring of Cancer Incidence in Japan (MCIJ) project. The incidence of only primary invasive cancer in Japan for 2009 was estimated to be 775 601. Stomach cancer and breast cancer were the leading types of cancer in males and females, respectively.
Background: The childhood cancer registry in Iran is a hospital-based system and there is not any unique and national registry system for pediatric malignancies in Iran. According to the limitations ...and requirements, this study was designed to clarify the aspect of childhood malignancies in Iran and promote establishing the Iranian national childhood cancer registry system.
Materials and Methods: This cross-sectional longitudinal study was implied on 1500 patients younger than 20-years old diagnosed with any malignancy and admitted at MAHAK Pediatric Cancer Treatment and Research Center (MPCTRC) from 2007 to 2014. Data collection was based on a validated questionnaire with three categories including demographic data, clinical data and type of malignancy, and outcomes. Collected data were analyzed using methods for qualitative and quantitative variables (P-Value < 0.05) by SPSS software version 22. The survival rate was calculated by the Kaplan-Meyer method.
Results: This study was implied on 1500 children with a mean age of 6.1 years old. The most common malignancy was acute leukemia (30.7%) followed by central nervous system tumors (27%). At the onset of starting treatment, the rate of conferring with relapse, metastasis, and secondary malignancies was 29%, 19.5%, and 1% respectively. In addition, 52 patients had bone marrow transplantation of whom, 14 cases died. Totally, 42% of patients died and the 3-years, 5-years, and 10-years overall survival rates were 67.7% ± 0.01, 60.3% ± 0.01, and 53.8% ± 0.01, respectively.
Conclusion: Establishing a population-based pediatric cancer registry in Iran is necessary and will be useful for improving the survival rate of mentioned patients.
Abstract Objective National Central Cancer Registry of China (NCCRC) updated nationwide statistics of cancer incidence and mortality in China using population-based cancer registration data in 2013 ...from all available cancer registries. Methods In 2016, 255 registries' data were qualified and included in this analysis. We estimated numbers of new cancer cases and deaths in China in 2013 using age-specific rates and corresponding national population stratified by area, sex, age group (0, 1–4, 5–9, 10–14…85+) and cancer type. The world Segi's population was applied for age-standardized rates. All rates were expressed per 100,000 person-year. Results A total of 3,682,000 new cancer cases and 2,229,300 cancer deaths were estimated in China in 2013. Cancers of lung, female breast, stomach, liver, colon-rectum and esophagus were the most common cancers, accounting for about half of all cancer new cases. Lung cancer, liver cancer, stomach cancer, esophageal cancer, colorectal cancer were the five leading causes of cancer death, accounting for about 60% of all cancer deaths. The cancer patterns showed differences not only between male and female, but also among different geographic regions in China. For overall cancers, the age-standardized incidence rates were stable during the past decades in male, but significantly increased by 2.2% per year in female. Conclusions Cancer poses a major threat to public health and the cancer burden keep raising in China. The annual updated cancer statistics can provide scientific basis for cancer prevention and control.
