e22108 Background: Acral Lentiginous melanoma (ALM) is a rare form of cutaneous melanoma with aggressive nature. This study investigates the incidence and survival patterns in patients diagnosed with ALM in USA from 1993-2013 using data from the Surveillance, Epidemiology, and End Results (SEER) Registry. Methods: The 18 cancer registries of SEER program were used to identify patients diagnosed with ALM according to international classification of diseases for oncology (ICDO-3) codes. Age adjusted incidence rates in addition to 5 and 10-year relative survival rates were calculated. Results: 2189 patients were included in this retrospective study.The age-adjusted incidence rate of ALM was 2.11 per million person-years.Hispanic whites had highest incidence rates of ALM among all racial subgroups ( 2.58, p = 0.005). Incidence of ALM was higher between 2003-2013 compared to 1993-2003 (2.3 vs 1.9).Median age at diagnosis was 61.68 years. 53.9 % were female. Our study population was dominated by Non-Hispanic Whites (69.2%) followed by Hispanic Whites (13.5%), Blacks (8.2%), Asians or Pacific Islanders (7.3%) and other races (1.8%). stage III was the most frequent (24.7%) followed by stage I (20.9%). In terms of tumor thickness, 43.2 % presented with T3 thickness at the time of diagnosis. The ALM 5 - and 10-year survival rates were highest in age < 40, females, T1, non ulcerated, lymph node negative lesions ( p < 0.05). Among racial subgroups, non Hispanic whites had highest survival rates (83 vs 74 % ). Asian/Pacific Islanders (75.1%vs 49.8%) had lowest survival rates followed Hispanic whites ( 76.4 % vs 63.9 ) and Blacks (74.7 vs 71.5 %) ( p = 0.19). Conclusions: ALM is rare subtype of cutaneous melanoma with increased incidence in people of color. Patients present with increased tumor thickness and advanced stage at the time of diagnosis. Poor survival rates are seen among Asian/Pacific Islanders and Hispanic whites.

Cancer Incidence Rates

PURPOSE Uterine corpus cancer incidence rates have been projected to increase, a prediction often attributed to the obesity epidemic. However, correct estimation of these rates requires accounting for hysterectomy prevalence, which varies by race, ethnicity, and region. Here, we evaluated recent trends in hysterectomy-corrected rates by race and ethnicity and histologic subtype and estimated differences in relative survival by race and ethnicity, subtype, and stage. METHODS We estimated hysterectomy prevalence from the Behavioral Risk Factor Surveillance System. Hysterectomy-corrected age-standardized uterine corpus cancer incidence rates from 2000 to 2015 were calculated from the SEER 18 registries. Incidence rates and trends were estimated separately by race and ethnicity, region, and histologic subtype. Five-year relative survival rates were estimated by race and ethnicity, histologic subtype, and stage. RESULTS Hysterectomy-corrected incidence rates of uterine corpus cancer were similar among non-Hispanic whites and blacks and lower among Hispanics and Asians/Pacific Islanders. Endometrioid carcinoma rates were highest in non-Hispanic whites, whereas nonendometrioid carcinoma and sarcoma rates were highest in non-Hispanic blacks. Hysterectomy-corrected uterine corpus cancer incidence increased among non-Hispanic whites from 2003 to 2015 and among non-Hispanic blacks, Hispanics, and Asians/Pacific Islanders from 2000 to 2015. Overall incidence rates among non-Hispanic blacks surpassed those of non-Hispanic whites in 2007. Endometrioid carcinoma rates rose among non-Hispanic blacks, Hispanics, and Asians/Pacific Islanders but were stable among non-Hispanic whites; however, nonendometrioid carcinoma rates rose significantly among all women. Non-Hispanic blacks had the lowest survival rates, irrespective of stage at diagnosis or histologic subtype. CONCLUSION Among all women, rates of nonendometrioid subtypes have been rising rapidly. Our analysis shows profound racial differences and disparities indicated by higher rates of nonendometrioid subtypes and poorer survival among non-Hispanic black women.

6003 Background: While smoking and alcohol are implicated in the majority of head and neck cancers, human papillomavirus (HPV) has been responsible for 15–35% of head and neck cancers worldwide. In head and neck sites such as the oropharynx, tonsil, and tongue, HPV is associated with 50–90% of squamous cell cancers. Recent recommendation of an HPV vaccine, protecting against infection with HPV types 16 and 18 have prompted this current assessment of the burden of squamous cell cancers (SCC) at these sites. Methods: Using data from CDC’s National Program of Cancer Registries and/or NCI’s SEER Program for cases diagnosed from 1998–2003, covering 83% of the U.S. population, we assessed the squamous cell cancers (SCC) of the base of tongue, oropharynx, and tonsil in the U.S. population on the basis of age group, gender, race/ethnicity, stage, US region, and year of diagnosis. Incidence rates were age- adjusted to the 2000 U.S. standard population and are expressed per 100,000 individuals. Results: The average annual incidence rates per 100,000 individuals during 1998–2003 are: base of tongue, 1.16 (95% confidence interval 1.14–1.18); oropharyngeal, 0.90 (95% CI 0.89–0.92); and tonsillar, 1.35 (95% CI 1.34–1.37). Blacks have the highest incidence of base of tongue, oropharyngeal, and tonsillar SCC (1.25, 1.61, and 1.47, respectively) while Asian/Pacific Islanders have the lowest incidence (0.37, 0.25, and 0.49, respectively). The South has the highest incidence of base of tongue, oropharyngeal, and tonsillar SCC (1.24, 1.06, and 1.52 respectively). Tonsillar cancer had the highest incidence rates for Whites, Asian/Pacific Islanders, American Indians/Alaska Natives, and Hispanics (1.37, 0.49, 0.85, and 0.89, respectively), but oropharyngeal cancer was the highest in Blacks (1.47). Both base of tongue and tonsillar SCC show a significant annual increase (2.68%, 2.96%, respectively). Conclusions: Increasing incidence rates among those head and neck cancers that are HPV- associated such as tonsillar and base of tongue suggest that the HPV vaccine may have a significant impact on these cancers. No significant financial relationships to disclose.

8Th Edition

Abstract Background. Previous studies have demonstrated racial and ethnic outcome disparities among differentiated thyroid cancer (DTC) patients. However, the impact of the 8th edition of the American Joint Committee on Cancer staging system (AJCC8) on these disparities is unknown. Methods. DTC patients with sufficient tumor and survival data were identified in the National Cancer Database from 2004-2013. The 7th edition of the staging system (AJCC7) and AJCC8 criteria were compared. Multivariable logistic regression was used to evaluate the association between AJCC7 to AJCC8 staging change and race and ethnicity. Cox-proportional hazards regression was then used to evaluate the association between AJCC7 to AJCC8 staging change and overall survival. Results. Of 33,323 DTC patients, 76.7% were White/Non-Hispanics, 7.6% Blacks, 6.7% Hispanics, 5.4% Asian/Pacific-Islanders, and 3.6% Native-American/Other. Most were female (77%) with papillary DTC (90%). After adjusting for demographic, tumor, and treatment characteristics, Hispanics and Asian/Pacific-Islanders were 27% and 12% less likely to be AJCC7 to AJCC8 downstaged than White/Non-Hispanics (OR=0.73, 95%CI: 0.66-0.81; and OR=0.88, 95%CI: 0.79-0.99, respectively); Blacks had no significant downstaging difference compared to White/Non-Hispanics (OR=0.99, 95% CI: 0.90-1.09, p=0.79). Although AJCC8 was a better survival prognosticator than AJCC7, Cox-proportional hazards regression showed that all AJCC7 to AJCC8 downstaged patients had an increased risk of death compared to patients with unchanged staging, regardless of race and ethnicity: White/Non-Hispanics (HR=2.64, 95%CI: 2.34-2.98), Blacks (HR=1.77, 95%CI: 1.23-2.54), Hispanic (HR=3.27, 95%CI: 2.05-5.22), Asian/Pacific-Islanders (HR=2.31, 95%CI: 1.35-3.98), and Native-American/Other (HR=5.26, 95%CI: 2.10-13.19). However, based on two way interaction, the magnitude of negative change in survival from downstaging was only different between White/Non-Hispanics and Blacks (HR=2.64 vs. HR=1.77, respectively; p=0.04). Conclusions. Racial and ethnic outcome disparities persist with AJCC8. The proportion of downstaged DTC patients with AJCC8 varies by race and ethnicity, with the least impact found in Hispanics and Asian/Pacific-Islanders. Downstaged patients across all racial and ethnic groups had a decreased survival than those with unchanged stage, with the least impact in Blacks. These disparities should be taken into account when counseling patients about their prognosis with the new AJCC8.

BACKGROUND: Esophageal adenocarcinoma has one of the fastest rising incidence rates and one of the lowest survival rates of any cancer type in the Western world. However, in many countries, trends in esophageal cancer differ according to tumour morphology and anatomical location. In Canada, incidence and survival trends for esophageal cancer subtypes are poorly known.METHODS: Cancer incidence and mortality rates were obtained from the Canadian Cancer Registry, the National Cancer Incidence Reporting System and the Canadian Vital Statistics Death databases for the period from 1986 to 2006. Observed trends (annual per cent change) and five-year relative survival ratios were estimated separately for esophageal adenocarcinoma and squamous cell carcinoma, and according to location (upper, middle, or lower one-third of the esophagus). Incidence rates were projected up to the year 2026.RESULTS: Annual age-standardized incidence rates for esophageal cancer in 2004 to 2006 were 6.1 and 1.7 per 100,000 for males and females, respectively. Esophageal adenocarcinoma incidence rose by 3.9% (males) and 3.6% (females) per year for the period 1986 to 2006, with the steepest increase in the lower one-third of the esophagus (4.8% and 5.0% per year among males and females, respectively). In contrast, squamous cell carcinoma incidence declined by 3.3% (males) and 3.2% (females) per year since the early 1990s. The five-year relative survival ratio for esophageal cancer was 13% between 2004 and 2006, approximately a 3% increase since the period from 1992 to 1994. Projected incidence rates showed increases of 40% to 50% for esophageal adenocarcinoma and decreases of 30% for squamous cell carcinoma by 2026.DISCUSSION: Although esophageal cancer is rare in Canada, the incidence of esophageal adenocarcinoma has doubled in the past 20 years, which may reflect the increasing prevalence of obesity and gastroesophageal reflux disease. Declines in squamous cell carcinoma may be the result of the decreases in the prevalence of smoking in Canada. Given the low survival rates and the potential for further increases in incidence, esophageal adenocarcinoma warrants close attention.

Objectives: Given the known high morbidity and mortality of hepatitis C virus (HCV) infection in Oregon, we sought to develop a practical method of estimating the severe sequelae of HCV infection among Medicaid beneficiaries in Oregon. Methods: We assembled a retrospective cohort that identified all Oregon Medicaid beneficiaries with HCV infection enrolled for at least 1 year during 2009-2013. We linked this cohort to 3 data sets to identify HCV-related deaths, cases of hepatocellular carcinoma (HCC), and first hospitalizations for advanced liver disease (ALD). We calculated incidence density rates and used multivariable Cox regression modeling to calculate adjusted hazard ratios (aHRs) to evaluate the association between demographic characteristics (birth year, sex, race, ethnicity) and these 3 outcomes. Results: Of 11 790 Oregon Medicaid beneficiaries with HCV infection, 474 (4.0%) had an HCV-related death, 156 (1.3%) had HCC, and 596 (5.1%) had a first hospitalization for ALD. Adjusted hazard ratios for deaths were 2.2 (95% confidence interval [CI], 1.6-2.8) among persons born in 1945 through 1965 (vs persons born after 1965), 2.1 (95% CI, 1.7-2.5) among males (vs females), and 1.9 (95% CI, 1.2-2.9) among Asian/Pacific Islanders and 2.2 (95% CI, 1.5-3.2) among American Indian/Alaska Natives (vs white persons). The same risk groups had significant aHRs for first hospitalizations for ALD. Persons born before 1945 (aHR = 17.0; 95% CI, 5.2-55.8) and in 1945 through 1965 (aHR = 12.8; 95% CI, 4.1-40.3) vs born after 1965, males (aHR = 3.3; 95% CI, 2.3-4.8) vs females, and Asian/Pacific Islanders (aHR = 3.9; 95% CI, 2.3-6.7) vs white persons had higher risks for HCC. Conclusions: Continued assessments using the methods piloted in this study will allow Oregon to monitor trends in severe sequelae of HCV infection over time.

Abstract INTRODUCTION: Metastases are oft-cited as comprising approximately half of all adult intracranial neoplasms, and their national composition remains unclear. METHODS: The patient demographics and histologic distribution of newly-diagnosed brain metastasis (BM) patients aged &gt; 18yo without a prior history of cancer (2010–2015) were evaluated using the National Cancer Database, which comprises &gt; 70% of all newly-diagnosed cancers in the U.S. RESULTS: 91,686 adults presented with a newly-diagnosed BM between 2010–2015. The most common sites of brain metastases overall were lung (82% of metastatic cases), breast (4.1%), melanoma (3.2%), kidney (2.9%), and colorectal (1.8%). The overall 1-year and 5-year OS rates for all BMs were 27.0% (95% CI [26.7%-27.3%]) and 5.3% (95% CI [5.1%-5.5%]), respectively. The distribution of primary sites for newly-diagnosed BMs varied by sex, age, and race. Compared to males, more females had BMs from breast (8.4% versus 0.8%) and fewer had BMs from kidney (1.9% versus 3.8%), melanoma (1.9% versus 4.5%), and esophagus (0.3% versus 2.0%). In young adults, particularly those 20-29yo, BMs were more likely from melanoma, genitourinary (in males), and soft tissue than adults in middle and advanced age. Lung carcinomas comprised fewer BMs in Hispanics (66%) compared to Whites (82%), Blacks (83%), and Asian/Pacific Islanders (85%). BMs from kidney and genitourinary primaries were higher in Hispanics (7.3% and 2.4% of BMs, respectively) than in Whites (2.8% and 0.3%, respectively), Blacks (1.8% and 0.1%, respectively), and Asian/Pacific Islanders (2.6% and 0.2%, respectively). Melanoma was more frequent in Whites (3.8% of BMs) and Hispanics (2.5%) compared to Blacks (0.3%) and Asian/Pacific Islanders (0.6%). CONCLUSION: Our results illustrate the national distribution of newly-diagnosed BMs and investigates how the distribution varies by patient demographics.

Abstract Background: Polycythemia vera (PV), essential thrombocythemia (ET) and myelofibrosis (MF) are clonal hematological disorders collectively named as myeloproliferative neoplasms (MPN). Discovery of JAK2 mutation in 2005, altered WHO classification for MPN diagnosis in 2008 and availability of new treatment of MPN may have substantial effect on epidemiology of MPN. Published data on epidemiology of MPN after the discovery of JAK2 mutation and the introduction of 2008 WHO classifications for MPN, in particular on the prevalence of MPN, are scarce. We aimed to study the epidemiology of MPN in Norway and to explore the impact of JAK-2 mutation and new guidelines on the incidence of MPN using data from the Norwegian cancer registry. Method: We identified 2344 persons diagnosed with MPN from the Norwegian Cancer Registry diagnosed between 1995 and 2012. Registration of cancer in the Norwegian Cancer Registry is mandatory according to the law. We report age-adjusted incidence, prevalence and relative survival of MPN. Age adjusted incidence was reported for 2 years periods from 1995 to 2012. The prevalence was calculated according to the Norwegian population per 31.12.2011. Results: A total of 945 cases of PV was identified with a median age at diagnosis of 70 years; 471 males (50%) and 474 females (50%). The overall age-adjusted incidence rate both genders was 0.4/10⁵ in 1995-1997, 0.5/10⁵ in 1998-2000, 0.7/10⁵ in 2001-2003, 0.8/10⁵ in 2004-2007, 2008-2009 and 0.7/10⁵ in 2010-12. We identified a total of 762 cases of ET with a median age at diagnosis of 65 years, 297 males (39%) and 465 females (61%). The overall age adjusted incidence rate both genders being 0.3/10⁵ in 1995-1997 and 1998-2000, 0.5/10⁵ in 2001-2003 and 2004-2006, 0.9/10⁵ in 2007-2009 and 2010-2012. A total of 418 cases of MF was identified with a median age at diagnosis of 71 years; 243 males (58%) and 175 females (42%). Age adjusted incidence rates of both genders were 0.2/10⁵ from 1995-2006, 0.3/10⁵ in 2007-2009 and 0.5/10⁵ in 2010-2012. There were a total of 219 persons with unclassified MPN both genders,119 males (54%) and 100 females (46%) and age adjusted incidence rate varied from 0.1-0.2 to 0.1/10⁵ 1995-2012. Per 31.12.2011 the prevalence of PV, ET and MF was 9.2, 8.6 and 3.0 per 10⁵ inhabitants respectively. The survival curves for males and females for the three conditions are shown in the figure. Conclusions: This population-based study shows that the incidence of ET and MF almost doubled during the years 2007-2012 as compared to 1995-2006 as shown in the table. This increment in the incidence may possibly be related to improved diagnostics including the JAK2 mutation and the introduction of 2008 WHO-guidelines for MPN. Surprisingly, the discovery of JAK2 does not seem to have had impact on the incidence of PV as indicated by steady incidence rates since 2001. The relative survival was only slightly reduced for PV and ET, but substantially reduced for MF. Only 50% of patients with MF survive for more than 5 years.

Abstract Background: The trends of incidence of solitary bone plasmacytoma (SBP) varied over time due to the changing definitions and the absence of clarity of the criteria. Prior studies have attempted to identify factors such as older age, gender, race as prognostic factors that influence survival of patients with SBP, but with changing paradigm of myeloma treatments, there is limited literature regarding the incidence, mortality and survival trends of SBP. Methods: We used the SEER registry from 1973-2009 to evaluate the incidence, mortality and survival trends in patients with SBP. The results were reported as crude incidence, mortality and survival rates. Two-sample t-tests, ANOVA as well regression analysis were used to examine correlation. Statistics were computed using the National Cancer Institute SEER*Stat software, version 8.2.0. and SAS software, version 9.4 (SAS Institute Inc, Cary, NC). Using the ICD-O-3 and morphologic codes of 9731/3 to identify cases, the final study cohort consisted of 2,734 cases. Trends were evaluated by the eras of diagnosis: 1973-1980, 1981-1985, 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2009. Age-adjusted incidence rates (IR), standard mortality rates (SMR), survival rate (SR) were expressed as new cases per 100,000 person-years, and age-adjusted to the 2000 US standard population. Results: The median age of diagnosis of SBP among blacks is 61 years (range, 21-91) compared to others: 60 years (range, 28-88) and whites: 66 years (20-97). The age adjusted incidence rates for black males is: 0.3 (95%CI 0.2, 0.3) followed by black females 0.2 (95%CI 0.1, 0.2) white males 0.2 (95%CI 0.2, 0.2) white females 0.1 (95%CI 0.1, 0.1). The trends in incidence and mortality rates are illustrated in table 1 with highest IR noted for black males during the era 2006-2009. The 5-year survival rates for both males (figure 1) and females (figure 2) seem to be trending down over the eras examined. Regression analysis suggests males and other race have increased odds of survival (HR = 0.829, p=0.0078; HR = 0.54 and p=0.0038, respectively). Conclusions: Similar to myeloma, black patients tend to be diagnosed with SBP younger and have increased incidence. The incidence rates seem to be increasing, highest among blacks males, more likely from increased awareness and diagnosis. The mortality and survival patterns are comparable to whites. Interestingly, while the 5-year survival for myeloma among all racial groups is improving this analysis shows a decreasing trend for SBP. This observation is more likely from including myeloma patients under the diagnosis of SBP over the period of study. Recently, the International Myeloma Working Group (IMWG) clarified the definition of SBP which will help in accurate diagnosis and ultimately can help in accurate representation of the survival trends.
