The aim of this study was to describe the incidence distribution of colorectal cancer in Fortaleza, Ceará State, and Porto Alegre, Rio Grande do Sul State, Brazil, and the time trend in the disease from 1990 to 1999. Mean annual age-adjusted incidence rates and estimated annual percent change were calculated by gender, using population-based cancer registries. EAPC showed an increase in the rates in Porto Alegre and Fortaleza for men, +4.2% (p = 0.14) and +9.3% (p < 0.001), and women, +4.6% (p = 0.11) and +5.3% (p = 0.15), respectively. The mean adjusted incidence rates were three times higher in Porto Alegre than in Fortaleza both for men (25.1 vs. 8.6/100 thousand) and women (19.9 vs. 7.1/100 thousand). This rise in incidence rates may be due to early cancer detection strategies, lifestyle changes, and alterations in the population age structure. A population profile similar to that of developed countries may explain the higher incidence rates in Porto Alegre. However, Fortaleza showed the largest increases during the period studied.

231 Background: Although multiple studies document a rise in gastroenteropancreatic neuroendocrine tumor (GEP-NET) incidence over the past several decades, there are limited national data regarding recent trends. Using a population-based registry, we evaluated GEP-NET incidence trends in the US population from 1975-2012 by age and calendar year at diagnosis and year of birth. Methods: GEP-NET cases between 1975-2012 were identified from the most recent version of the Surveillance, Epidemiology, and End Results (SEER) registry based on histologic and site codes. We calculated overall annual incidence, age-adjusted incidence (number of cases per 100,000), annual percent change (APC), and average APC by 5 year age intervals. We also evaluated the incidence rates by age, period, and birth year cohorts. Results: We identified 22,744 patients with GEP-NETs. In adults age 25-39 years, GEP-NET incidence rates declined from the mid 1970s to early 1980s, then increased until 2012 (Table 1). In adults age 40 and older and between ages 15-24 years, incidence rates generally increased continuously from 1975 to 2012. Adults age 40-69 years demonstrated the most rapid increases in average APC, approximately 4-6% per year. Overall incidence rates were highest in adults age 70-84 years. Since the late 1880s, GEP-NET incidence has increased in consecutive birth cohorts. Conclusions: Our study demonstrates that more recent generations have had higher incidence rates than more distant generations. In addition, GEP-NETs are more common among older adults and the number of GEP NETs has increased in past decades. [Table: see text]

Abstract Background : The exhaustive collection of new sarcoma cases and their second histologic review offer a unique opportunity to study their incidence and time trends in France according to the major subtypes. Methods : Data were collected from population-based cancer registries covering 22% of the French population. Crude and world age-standardized incidence rates (ASR) were estimated according to anatomic, histological and genetic groups, age and sex over the 2010-2013 period. Results: Time trends in incidence were calculated by the annual percent change over the 2000-2013 period. During the most recent period (2010-2013), 3,942 patients with sarcoma were included. The ASR of soft-tissue and bone sarcomas, and gastro-intestinal stromal tumors (GIST) were 2.1, 1.0 and 0.6, respectively. For the four most frequent histological subtypes (unclassified, leiomyosarcoma, GIST and liposarcoma), the ASR ranged from 0.4 to 0.7. ASRs were 1.9 for complex genomic and 1.3 for recurrent translocation sarcomas. The time-trend analysis showed a significant increase of sarcoma incidence rate between 2000 and 2005, which stabilized thereafter. Incidence rates increased for four histological subtypes (GIST, chondrosarcoma, myxofibrosarcoma, solitary fibrous tumors) and decreased for three (leiomyosarcomas, Kaposi sarcoma and fibrosarcoma). Conclusion : To our knowledge, this study is the first to investigate sarcoma incidence based on a systematic pathological review of these cancers and on the updated sarcoma classifications. Due to the paucity of literature on sarcomas, future studies using data from population-based cancer registries should consider a standardized inclusion criterion presented in our study to better describe and compare data between countries.

AbstractComprehensive population-based data on myeloid neoplasms (MNs) are limited, mainly because some subtypes were not recognized as hematological cancers prior to the WHO publication in 2001, and others are too rare to allow robust estimates within regional studies. Herein, we provide incidence data of the whole spectrum of MNs in Spain during 2002–2013 using harmonized data from 13 population-based cancer registries. Cases (n = 17,522) were grouped following the HAEMACARE groupings and 2013-European standardized incidence rates (ASRE), incidence trends, and estimates for 2021 were calculated. ASRE per 100,000 inhabitants was 5.14 (95% CI: 5.00–5.27) for myeloproliferative neoplasms (MPN), 4.71 (95% CI: 4.59–4.84) for myelodysplastic syndromes (MDS), 3.91 (95% CI: 3.79–4.02) for acute myeloid leukemia, 0.83 (95% CI: 0.78–0.88) for MDS/MPN, 0.35 (95% CI: 0.32–0.39) for acute leukemia of ambiguous lineage, and 0.58 (95% CI: 0.53–0.62) for not-otherwise specified (NOS) cases. This study highlights some useful points for public health authorities, such as the remarkable variability in incidence rates among Spanish provinces, the increasing incidence of MPN, MDS, and MDS/MPN during the period of study, in contrast to a drop in NOS cases, and the number of cases expected in 2021 based on these data (8446 new MNs).

e12528 Background: Colorectal cancer (CRC) incidence has decreased over the past three decades, due in part to screening for pre-malignant polyps. Relatively little is known about CRC incidence among adults under age 50 (when screening recommendations commence for average-risk individuals). We examined CRC incidence trends with a focus on adults under age 50, in order to identify high-risk subgroups. Methods: 231,544 incident CRC cases (including 21,220 adults <50) from the California Cancer Registry from 1988-2009 were analyzed. We assessed age-specific incidence rates by race/ethnic group, gender, and tumor location within the colorectum, and calculated annual percent change (APC) to monitor change in incidence over the 21-year study period. Results: We observed increased CRC incidence rates in the adult population under age 50 in all examined race/ethnic groups, especially in Hispanic males (APC=+7.5%/p=0.0001) and Caucasian females (APC=+6.5%/p<0.0001). Young individuals were also more likely to present with metastatic disease at diagnosis. Overall, African Americans had the highest overall incidence rates and were most likely to present with metastatic disease compared to other groups. Conclusions: Incidence of CRC in adults under 50 is increasing across all race/ethnic groups. The high frequency of metastatic disease at initial presentation in this age group is particularly concerning. However, a considerable limitation of this analysis is the lack of data on family history of CRC. Our observations highlight the importance of identifying at-risk adults under age 50, especially those in higher-risk race/ethnic groups, with the overarching goal of decreasing the burden of CRC through screening and early detection.

Aims and background The study aimed to validate model-based incidence estimates by means of observed incidence rates provided by Italian cancer registries, for five major cancer sites (stomach, colon and rectum, lung, breast and prostate cancers) and for all cancers together. Methods Recent incidence rates observed by Italian population-based cancer registries were extracted from the data base of the Italian Association of Cancer Registries. Regional estimates of incidence rates for the same cancers were obtained by the MIAMOD method. Observed and estimated crude incidence rates and incidence trends were compared for the period of diagnosis 1985-2000. Eight Italian cancer registries and seven regions were selected for the analysis since they had incidence data available during the entire selected period. Results and conclusions An excellent agreement between estimated and observed crude incidence rates was found for all single cancer sites, regarding absolute incidence levels and time trends. A partial exception was breast, where empirical data showed a sudden increase in the last three years of observation, perhaps due to organized screenings in some Italian regions, and not captured by statistical models. Substantial underestimation of model-based incidence rates was found for all cancers combined, where the difference tended to increase with calendar year, up to a maximum of 20% in recent years. The greatest part of the discrepancy can be attributed to multiple cancers, which were included in cancer registries statistics but were not accounted for in MIAMOD estimates.

Abstract Background The aim of this study is to identify the incidence trends of primary and secondary peritoneal surface malignancies in a representative Czech population. Methods Data were obtained from patients registered in the Czech National Cancer Registry between 1979 and 2016. The incidence rates were analyzed between 2012 and 2016. To observe the incidence trends, we analyzed the data from two time periods, 1979–2005 and 2006–2016. The analyzed data included age, sex, and the histological types and primary origins of the malignancies. The Cochrane-Armitage test for linear trends was used for verification of the null hypothesis. The significance level established for hypothesis testing was p = 0.05. Results Between 2012 and 2016, 230 patients with primary peritoneal tumors were identified and divided into the following groups according to their “International Statistical Classification of Diseases and Related Health Problems, 10th revision” codes: malignant neoplasm of specified parts of the peritoneum (C48.1); malignant neoplasm of the peritoneum, unspecified (C48.2); and malignant neoplasm of overlapping sites of the retroperitoneum and peritoneum (C48.8). Moreover, 549 primary tumors of the appendix (C18.1, encompassing all appendiceal malignancies) and 3137 secondary synchronous peritoneal carcinomatoses of other primary origins were documented. The age-adjusted incidence of primary peritoneal tumors in 2012–2016 was 4.36/year/1,000,000 inhabitants. The age-adjusted incidence of synchronous secondary peritoneal malignancies in 2014–2016 was 99.0/year/1,000,000 inhabitants. The diagnoses of primary peritoneal malignancies followed a stable trend between 1979 and 2016. However, the incidences of primary tumors of the appendix increased by 76.7%. Conclusions The data produced in our study ought to clarify the status of peritoneal surface malignancies in the Czech Republic, which can lead to improved planning and development of therapeutic interventions as well as physician training.

Objective: A comprehensive coordinated effort was undertaken by National Cancer Registry Programme (NCRP) and its coordinating unit in an Indian State – Haryana, to map cancer incidence, to provide regional overview of geographical patterns of Cancer within state of Haryana to serve as basis for informing public and policy makers. Methods: Information on new cases, residents of Haryana state, and diagnosed with cancer during years 2016 -17 was collected from several medical set-ups in 21 districts across Haryana and its neighboring states. Data received from Hospitals registered under NCRP was also included. Age-Adjusted incidence Rates (AARs) were calculated by gender and site for each district in State. All districts were used for comparison of AARs with rates to those from established population based cancer registries. Cumulative risk of developing cancer was calculated.Results: Data from 36736 cases was collated. Comparison of AARs revealed that there are high incidence rates of head and neck cancers in males, whereas cancer breast was leading site in females. Relative proportions of cancers of sites associated with use of tobacco, were found high in some semi-urban districts of state. Project has recognized and substantiated need of setting up of screening programmes and Population Based Cancer Registry in Haryana. The study was done using an electronic data-capture methodology which is remarkably cost-effective and provides a model for health informatics in setting of developing country.Conclusion: Contiguous areas of high incidence of cancer recorded in state have shown higher rates of tobacco related cancers (Head & Neck, Lung) necessitating rigorous control on tobacco usage. Higher incidence of certain cancers associated with reproductive system of both men (prostate) and women (cervix and breast) implicates factors such as lifestyle changes due to urbanization. Overall, the project is a step towards good cancer statistics availability in the country.

Colorectal Cancer Incidence

e16084 Background: Colorectal cancer (CRC) accounts for 10% of global cancer deaths yearly. It is postulated that the incidence rates are rising in developing countries like India. We present a comprehensive overview of colorectal cancer incidence in India from various regions from 2004 to 2014. Methods: We obtained data on CRC incidence from the Population Based Cancer Registries (PBCR) of the National Cancer Registry Program. We calculated age-standardized incidence rates (to WHO World Standard Population 2000) for five-year age groups for period of diagnosis (2004-05, 2006-08, 2009-11, and 2012-14). Results: From 2004 to 2014, CRC incidence rates in India increased by 20%. During 2004-2005, the incidence rate of CRC was 5.8 per 100,000 persons. It increased to 6.9 during 2012-2014. Conclusions: CRC rates are rising in India. Even though the absolute rates are low in the Indian population, the rising rates pose a problem in rising cancer morbidity in India. The rising rates can be attributed to changing lifestyles that include consumption of calorie-rich and low fibre diet, excessive use of red meat and processed foods, and physical inactivity. There is a need for cost-effective strategies to enable early diagnosis for colorectal cancer in India. Affordable and equitable treatment will help increase the 5-year survival rates of colorectal cancers. [Table: see text]

ObjectivesTo examine trends in the incidence of rheumatoid arthritis (RA) from 2005 to 2014 overall and by serological status as compared with 1995–2004 and 1985–1994.MethodsWe evaluated RA incidence trends in a population-based inception cohort of individuals aged ≥18 years who first fulfilled the 1987 American College of Rheumatology (ACR) criteria for RA between 1 January 1985 and 31 December 2014. Incidence rates were estimated and were age-adjusted and sex-adjusted to the white population in the USA in 2010. Trends in incidence were examined using Poisson regression methods.ResultsThe 2005–2014 incidence cohort comprised 427 patients: mean age 55.4 years, 68% female, 51% rheumatoid factor (RF) positive and 50% anti-cyclic citrullinated peptide antibody positive. The overall age-adjusted and sex-adjusted annual RA incidence in 2005–2014 was 41/100 000 population (age-adjusted incidence: 53/100 000 in women and 29/100 000 in men). While these estimates were similar to the 1995–2004 decade, there was a decline in the incidence of RF-positive RA in 2005–2014 compared with the previous two decades (p=0.004), with a corresponding increase in RF-negative cases (p<0.001). Smoking rates declined and obesity rates increased from earlier decades to more recent years.ConclusionsSignificant increase in incidence of RF-negative RA and decrease in RF-positive RA in 2005–2014 compared with previous decades was found using 1987 ACR criteria. The incidence of RA overall during this period remained similar to the previous decade. The changing prevalence of environmental factors, such as smoking, obesity and others, may have contributed to these trends. Whether these trends represent a changing serological profile of RA requires further investigation.

Background. We aimed to investigate age-specific and sex-specific incidence trends of melanoma in Lithuania from 1991 to 2015. Methods. Analysis was based on data from the population-based Lithuanian Cancer Registry database for 1991–2015, and 6024 cases of skin melanoma were identified. Age-adjusted rates (ASRs) by sex and age group were calculated. Adjustment for ASRs was done using the old European standard population, where a total of three age groups were considered: 0–39, 40–59 and 60+. Additionally, the annual percent change (APC) was calculated, and 95% confidence intervals for APC were calculated. Results. Between 1991 and 2015, the overall melanoma rates increased by an annual percent change (APC) of 3.9% in men (95% CI, 3.6–4.1%) and 2.3% in women (95% CI, 2.1–2.5%). The highest incidences of new cutaneous melanoma cases were observed between old adults (60+) of both sexes, while the lowest incidence rates were observed in the young adult group (up to 39 years old), with the lowest APC (1.6% in males and 0.4% in females). The overall number of melanoma deaths during 1991 and 2015 increased from 64 to 103 deaths per year, and the age-standardized rate (ASR) increased 1.3 times (from 1.8 to 2.4). Conclusions. The incidence and mortality of skin melanoma seem to be increased in all age groups. These trends indicate that skin protection behavior is not sufficient in our population and more efforts need to be taken in order to decrease incidence and mortality rates.
