Abstract BACKGROUND: Incidence rates for myelodysplastic syndromes (MDS) and chronic myeloproliferative disorders (CMD) in the United States were unavailable prior to the addition of these stem cell malignancies to the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program and other central cancer registries in 2001. Description of national incidence rates for 2001–2003 will provide an important baseline for future studies of secular trends and allow for the examination of rates by selected demographic factors to define risk profiles of these malignancies in the American population. METHODS: Incidence rates of MDS and CMD were calculated for 18 SEER areas between 2001–2003. These rates were stratified by disease subtype using the FAB classification (including chronic myelomonocytic leukemia [CMML]) with the addition of the WHO deletion 5q category, sex, age at diagnosis and race. Based on the observed SEER incidence rates, counts were estimated for the entire U.S. population. RESULTS: In 2003, 2,538 cases of MDS and 1,421 cases of CMD were observed for all 18 SEER areas combined. Similar numbers of cases were observed in 2001 and 2002. Age-adjusted incidence rates for 2001–2003 were significantly higher among males than females for MDS (4.5 per 100,000 in males vs. 2.7 per 100,000 in females, p <0.0001) and CMD (2.4 per 100,000 in males vs. 1.7 per 100,000 in females, p<0.0001). This gender rate difference was observed consistently across all disease subtypes, including refractory anemia (2.0 per 100,000 in males vs. 1.2 per 100,000 in females (p<0.0001). Incidence rates were significantly associated with age at diagnosis for both MDS (p=0.01) and CMD (p=0.001), and were highest among White, non-Hispanics (2.4 per 100,000 for CMD; 4.2 per 100,000 for MDS). An estimated national total of 14,648 cases of MDS (including CMML) and CMD were diagnosed in 2003, with overall incidence rates for MDS and CMD of 3.1 and 1.9 per 100,000, respectively. The MDS incidence rate for the U.S. is remarkably similar to those previously reported from European countries including England and Wales (3.6 per 100,000), Germany (4.1 per 100,000), Sweden (3.6 per 100,000) and France (3.2 per 100,000). Estimated incidence rates in the U.S. were greater among men than women for all diseases, including CMML (0.40 per 100,000 in males versus 0.3 per 100,000 in females, p< 0.0001). Disease incidence increased with age for MDS, CMD, and CMML, although the increase was greatest for MDS, with an approximate five-fold difference in estimated rates for those diagnosed at ages 60–69 years vs. 80 years and older (7.4 per 100,000 vs. 36.3 per 100,000). The increase in MDS incidence with age was greater for males than females, whereas the age-related increase in CMD and CMML incidence was similar across sexes. Rates of CMD, MDS and CMML were all estimated to be highest among White, non-Hispanics. CONCLUSION: Male sex and advanced age are important risk factors for the development of CMD and MDS. Diagnostic recording differences may underestimate the total annual U.S. MDS and CMD case burden. Future prevention intervention and disease causality studies of MDS and CMD should target high-risk groups.

Abstract Reporting of myelodysplastic syndromes (MDSs) and chronic myeloproliferative disorders (CMDs) to population-based cancer registries in the United States was initiated in 2001. In this first analysis of data from the North American Association of Central Cancer Registries (NAACCR), encompassing 82% of the US population, we evaluated trends in MDS and CMD incidence, estimated case numbers for the entire United States, and assessed trends in diagnostic recognition and reporting. Based on more than 40 000 observations, average annual age-adjusted incidence rates of MDS and CMD for 2001 through 2003 were 3.3 and 2.1 per 100 000, respectively. Incidence rates increased with age for both MDS and CMD (P < .05) and were highest among whites and non-Hispanics. Based on follow-up data through 2004 from the Surveillance, Epidemiology, and End Results (SEER) Program, overall relative 3-year survival rates for MDS and CMD were 45% and 80%, respectively, with males experiencing poorer survival than females. Applying the observed age-specific incidence rates to US Census population estimates, approximately 9700 patients with MDS and 6300 patients with CMD were estimated for the entire United States in 2004. MDS incidence rates significantly increased with calendar year in 2001 through 2004, and only 4% of patients were reported to registries by physicians' offices. Thus, MDS disease burden in the United States may be underestimated.

357 Background: Anal squamous cell carcinoma (SCC) is rare, but results in significant morbidity and mortality. The aim of this study was to characterize the trends of anal SCC in the U.S. between 1980-2009. Methods: Subjects were identified from records in the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program. The study included incident malignant squamous cell cancer of the anus, anal canal, and anorectum diagnosed among nine core areas of the SEER program from 1980-2009. Average annual age-adjusted incidence rates were calculated by the direct method with the U.S. 2000 standard population. 95% confidence intervals were calculated using the Tiwari adjustment. Temporal trends were assessed by joinpoint regression. Results: Incidence rates of anal cancer in the U.S. more than doubled during this period. A linear increase in anal cancer incidence rates was observed with an Annual Percent Change (APC) of 4.6 (p<0.01) for all races and both sexes-combined. Incidence rates were consistently greater for women than men, however, the increase in incidence rates was greater for men (APC=5.4, p<0.01) than for women (APC=4.3, p<0.01). Similar trends were seen for whites and blacks. Conclusions: Anal cancer is a relatively rare disease, yet incidence rates increased dramatically in the U.S. over the last three decades. Correlation of this increased incidence with HPV infection remains to be determined. [Table: see text]

Background. We sought to determine the prevalence of skin conditions traditionally associated with acute ischemic stroke (AIS) and transient ischemic attacks (TIA) in the U.S. Methods. This is a cross-sectional study of data derived from the National Inpatient Sample from 1988-2008. We searched for admissions of patients <18 years, with a primary diagnosis of AIS, TIA, and the following secondary diagnoses (dermatoses): Psoriasis, Behcet’s Disease (BD), Dermatomyositis (DM), Systemic Lupus Eythematosis (SLE), Pseudoxanthoma Elasticum (PXE), Progressive Systemic Sclerosis or Scleroderma (SCD), and Bullous Pemphigoid (BP). Definitions were based on ICD9CM codes, and adjusted incidence rates for the U.S census and prevalence proportions were then calculated. Results. Over the 20-year period, we identified 9,085,147 admissions that corresponded to a primary diagnosis of AIS and TIA of which 53,060 had a secondary diagnosis of dermatoses, for a total prevalence of 0.6%. The adjusted rate of AIS/TIA increased from 71/100,000 in 1988 to 200/100,000 in 2008. Among the secondary diagnosis, the most prevalent condition after AIS/TIA admissions was SLE (54%), psoriasis (34%), SCD (9%), BP (2%), DM (1%), PXE (0.5%), and BD (0.14%). The prevalence of these dermatoses increased from 0.2% in 1988 to 0.8% in 2008 ( Figure 1 ). Conclusion. Despite an overall increase in the prevalence of dermatoses, these skin conditions remain a rare occurrence in AIS/TIA. The over-representation of traditional risk factors for AIS/TIA in patients with these dermatoses, may explain the observed epidemiological phenomenon.

Abstract Background Because in the past Chronic Myeloproliferative Disorders (CMPD) were not considered to be malignant conditions, cancer registries rarely recorded data on these diseases. Thus, information on incidence and outcome of CMPD in the population is limited. The aim of the present study was to better define epidemiological data of CMPD by examining all cases identified by the Modena Cancer Registry (MCR). Materials and methods We considered all cases of CMPD diagnosed in the Province of Modena (population 633.993 at 2001 Census). Cases, except Chronic Myeloid Leukemia, diagnosed from 1997 to 2005, were identified using the MCR database and the archival files of the centralized hemolymphopathological laboratory at Modena Cancer Centre according to ICD-O-3 codes 9950, 9960–64. Death certificate, cytology and histology report, both local and national reports of hospital admission, ICD-9 code reported in medical records were used as sources for identifying new CMPD cases and their outcome. All cases were checked and validated by a hematologist (A.B.) and a pathologist (G.B.) by a review of the original pathology report. Uniform diagnostic criteria were adopted, because the large majority of bone marrow aspirate and biopsy were examined by the same pathologist (G.B.). Clinical and follow-up data were retrieved by active search of discharge letters, review of hospital records and interview of general practitioners. Information on vital status was achieved from official population registries. Age standardized rates (ASR) were calculated according to the World Standard population. The dates of diagnosis and death or the closing date of study (December 2006) were used to estimate survival. Observed survival and relative survival were calculated according to Kaplan-Meier method and the Hakulinen approach, respectively. Results According to the 2001 World Health Organization (WHO) classification, a total of 380 cases of CMPD were identified. There were 155 Essential Thrombocythemia (ET) (41% of all CMPD), 114 Policythemia Vera (PV) (30%), 75 Idiopathic Myelofibrosis (20%), 2 Hypereosinophilic Syndrome/Chronic Eosinophilic Leukaemia (0.5%), 1 Chronic Neutrophilic Leukemia (0.3%) and 31 CMPD not otherwise specified (8%). The ASR of CMPD was 3.2/100,000 varying slightly (from 2.5 to 4.1/100,000) during the study period (p = 0.11); the crude incidence rate was 6.6/100,000. Median age at diagnosis was 69 years. No statistically significant differences were observed between sex regarding incidence and age at diagnosis. Overall relative survival was 97%, 89% and 88% at 1, 3 and 5 years after diagnosis, respectively. Analyzing CMPD, we observed a better survival for ET and PV in comparison with other subtypes (p = 0.01). Conclusions To our knowledge, this study is the first in Italy providing information on the incidence and outcome of CMPD using population-based data. Our results confirm that the risk of developing CMPD increases with age. The incidence of CMPD was substantially stable during the study period. Overall survival patterns reflect the well known chronic course of these diseases. As expected, we observed important differences in overall survival by WHO subtypes. We believe that the availability of precise epidemiological data, in particular those regarding outcome could help clinicians in choosing the most appropriate cost-effective treatments.

Abstract Evolving data demonstrate the pathogenetic significance of chromosomal ends telomeres and telomerase activity in the molecular pathogenesis of many hematological disorders. Furthermore, the presence of eroded telomeres and enhanced telomerase activity in hematopoietic cells has been associated with poor prognosis both in myeloid and lymphoid malignancies. The aim of the present study was to evaluate telomere length and telomerase activity in patients with Ph1-negative Chronic Myeloproliferative Disorders (Ph−-CMPD) either at diagnosis or during the course of the disease and to assess their possible clinical utility. Sixty-six bone marrow and 60 peripheral blood samples were obtained from 80 Ph−-CMPD patients (aged 58.57±16.42 years) and 18 healthy age-matched controls (aged 53.94±15.16 years). Thirty-six patients diagnosed suffering from Polycythemia Vera, 36 from Essential Thombocythemia, 4 from Idiopathic Myelofibrosis and 4 from Unclassified CMPD. Twenty-six samples were studied at diagnosis, whereas 54 during the course of the disease. Telomere length analysis of individual chromosome ends was performed on bone marrow metaphases using Telomere/Centromere Quantitative-Fluorescence In Situ Hybridization (T/C Q-FISH) (Dako A/S, Denmark). Telomerase activity was determined in bone marrow purified CD34(+) and CD20(+) cells as well as in peripheral blood CD3(+) T-lymphocytes and granulocytes with the PCR-based Telomeric Repeat Amplification Protocol (TRAP) assay (Roche, Germany). Gene expression of telomerase-associated proteins (hTERT, hTER, TEP1, TRF-1 and TRF-2) was assayed by Real-Time Multiplex PCR (Maximbio, USA). Ph−-CMPD patients showed significantly more eroded telomeres (P=0.010) and increased telomerase activity in CD34(+) cells (P=0.005) compared to healthy age-matched individuals. However, there was no statistical difference in telomere length (P=0.451) and enzyme activity (P=0.538) among different groups of Ph−-CMPD. Telomerase activity was not detected in the remaining hematopoietic cells both in patients and healthy controls, which was closely correlated with downregulation in hTERT mRNA expression. hTER, TEP1, TRF-1 and TRF-2 showed no apparent differential expression of mRNA in all hematopoietic cell fractions. Chromosomal aberrations (+8, +9, del13q14, del20q12) were found by FISH in 37% Ph−-CMPD patients with reduced telomere lengths (P=0.001) and enhanced telomerase activity (P=0.014), especially during the course of the disease (P=0.028). The patients with shortened telomeres displayed a higher incidence of having thrombotic or hemorrhagic events during follow-up (P=0.011), treatment failure (P=0.024) and disease progression to myelofibrosis, myelodysplastic syndromes, secondary leukemia or death (P=0.137). Nevertheless, telomerase expression was not correlated with the above complications. The event free survival (survival without complications, e.g. myelofibrosis, myelodysplastic syndromes, secondary leukemia and death) was significantly shorter in patients with reduced telomere lengths (Log Rank P=0.033), who demonstrated a 7,71-fold higher probability of having complications within five years from the initial diagnosis (95% CI=2,04–31,49 P&lt;0.001). In conclusion, accelerated telomere shortening may not be prevented or restored by telomerase activity in most of the Ph−-CMPD myeloid cells. Loss of telomere stability seems to predispose to further genetic events such as chromosomal rearrangement and consequently to trigger off a multistage neoplastic transformation of these diseases. Moreover, the negative correlation between telomere length and survival probability of Ph−-CMPD patients is indicative that telomere dynamics may serve as a useful prognostic tool for these patients.

Abstract Background In Los Angeles County, the tuberculosis (TB) disease incidence rate is seven times higher among non-U.S.-born persons than U.S.-born persons and varies by country of birth. But translating these findings into public health action requires more granular information, especially considering that Los Angeles County is more than 4000 mile2. Local public health authorities may benefit from data on which areas of the county are most affected, yet these data remain largely unreported in part because of limitations of sparse data. We aimed to describe the spatial distribution of TB disease incidence in Los Angeles County while addressing challenges arising from sparse data and accounting for known cofactors. Methods Data on 5447 TB cases from Los Angeles County were combined with stratified population estimates available from the 2005–2011 Public Use Microdata Survey. TB disease incidence rates stratified by country of birth and Public Use Microdata Area were calculated and spatial smoothing was applied using a conditional autoregressive model. We used Bayesian Poisson models to investigate spatial patterns adjusting for age, sex, country of birth and years since initial arrival in the U.S. Results There were notable differences in the crude and spatially-smoothed maps of TB disease rates for high-risk subgroups, namely persons born in Mexico, Vietnam or the Philippines. Spatially-smoothed maps showed areas of high incidence in downtown Los Angeles and surrounding areas for persons born in the Philippines or Vietnam. Areas of high incidence were more dispersed for persons born in Mexico. Adjusted models suggested that the spatial distribution of TB disease could not be fully explained using age, sex, country of birth and years since initial arrival. Conclusions This study highlights areas of high TB incidence within Los Angeles County both for U.S.-born cases and for cases born in Mexico, Vietnam or the Philippines. It also highlights areas that had high incidence rates even when accounting for non-spatial error and country of birth, age, sex, and years since initial arrival in the U.S. Information on spatial distribution provided here complements other descriptions of local disease burden and may help focus ongoing efforts to scale up testing for TB infection and treatment among high-risk subgroups.

Prediction of the COVID-19 incidence rate is a matter of global importance, particularly in the United States. As of 4 June 2020, more than 1.8 million confirmed cases and over 108 thousand deaths have been reported in this country. Few studies have examined nationwide modeling of COVID-19 incidence in the United States particularly using machine-learning algorithms. Thus, we collected and prepared a database of 57 candidate explanatory variables to examine the performance of multilayer perceptron (MLP) neural network in predicting the cumulative COVID-19 incidence rates across the continental United States. Our results indicated that a single-hidden-layer MLP could explain almost 65% of the correlation with ground truth for the holdout samples. Sensitivity analysis conducted on this model showed that the age-adjusted mortality rates of ischemic heart disease, pancreatic cancer, and leukemia, together with two socioeconomic and environmental factors (median household income and total precipitation), are among the most substantial factors for predicting COVID-19 incidence rates. Moreover, results of the logistic regression model indicated that these variables could explain the presence/absence of the hotspots of disease incidence that were identified by Getis-Ord Gi* (p < 0.05) in a geographic information system environment. The findings may provide useful insights for public health decision makers regarding the influence of potential risk factors associated with the COVID-19 incidence at the county level.

22 Background: Esophagogastric junction cancer (EGJC) has recently been included within the esophageal cancer (EC) AJCC TNM staging criteria. Trends in clinical presentation, therapeutic approach and outcomes are of interest. Methods: We identified EGJCs from the U.S. population SEER database and examined incidence, demographic, therapeutic and outcomes information. Siewert classification-related EGJC subtype-associated findings were also examined. Results: EGJC age-adjusted incidence rates (x10-5) have increased from 3.3 in 1973 to 7.5 in 2009. While the incidence rate for females has remained around 2, rates in males have increased from 6 to 13. Among 30,710 EGJC patients diagnosed between 1992 and 2009, potentially curative resection increased from 31% to 36% and radiation increased from 32% to 41% (p<0.0001). For resected EGJCs, significant trends over time include: increased total LN count (mean: 15.5 vs. 12.3), fewer positive LNs (3.1 vs. 4), smaller tumor size (29% vs. 36% >5 cm), lower T category (39% vs. 29% T1/2), lower N category (42% vs. 35% N0), lower stage group (29% vs. 38% stage 3/4), increased preoperative radiation (26% vs. 3%), decreased 90-day mortality (6.5 vs. 14.1%), longer overall survival (OS, median: 2.9 vs. 1.7 years) and longer disease-specific survival (median: 3.9 vs. 2.0 years) (all at p<0.0001). Multivariate predictors of OS include TNM categories, age, ethnicity, radiation, and total LN count (all at p<0.0001). There were significant differences in stage-for-stage OS between EC subtypes based on histology and primary tumor location, and in DSS between EGJC subtypes (Siewert I, II or III) as well. Conclusions: EGJC incidence rates, diagnosis and treatment have undergone significant changes within the U.S. population. The regional dissection extent remains an area of importance as it is associated with OS. Comparisons of various survival outcomes do not support using the same staging criteria for EGJC as for EC.

The aim of this study was to associate lifestyle characteristics with COVID-19 infection and mortality rates at the U.S. county level and sequentially map the impact of COVID-19 on different lifestyle segments. We used analysis of variance (ANOVA) statistical testing to determine whether there is any correlation between COVID-19 infection and mortality rates and lifestyles. We used ESRI Tapestry LifeModes data that are collected at the U.S. household level through geodemographic segmentation typically used for marketing purposes to identify consumers’ lifestyles and preferences. According to the ANOVA analysis, a significant association between COVID-19 deaths and LifeModes emerged on 1 April 2020 and was sustained until 30 June 2020. Analysis of means (ANOM) was also performed to determine which LifeModes have incidence rates that are significantly above/below the overall mean incidence rate. We sequentially mapped and graphically illustrated when and where each LifeMode had above/below average risk for COVID-19 infection/death on specific dates. A strong northwest-to-south and northeast-to-south gradient of COVID-19 incidence was identified, facilitating an empirical classification of the United States into several epidemic subregions based on household lifestyle characteristics. Our approach correlating lifestyle characteristics to COVID-19 infection and mortality rate at the U.S. county level provided unique insights into where and when COVID-19 impacted different households. The results suggest that prevention and control policies can be implemented to those specific households exhibiting spatial and temporal pattern of high risk.
