171 Background: The increased incidence of gastro-esophageal junction adenocarcinoma has been well-described, but how the proportion of early versus older onset cancer has changed over time remains incompletely understood. This study characterized the socioeconomic and pathologic characteristics of early-onset gastro-esophageal malignancies. Methods: All patients with gastric cancer (GC) and esophageal cancer (EC) from 2004-2015 in the National Cancer Database were included and categorized by age under or over 60 years. Differences in demographics, disease stage, treatment characteristics and socioeconomic factors between young and older patients were assessed by Chi-square test. The effect of age, race, insurance status, community median income and community educational attainment on overall survival (OS) were assessed using uni- and multivariable Cox models with Bonferonni correction when indicated. Results: The study population comprised 158,599 patients with GC and 139,210 patients with EC. For GC, 43,146 patients (27.2%) were under age 60. The proportion of patients diagnosed under 60 increased over time: 26.7% in 2004-2006, 26.9% in 2007-2009, 27.6% in 2010-2012 and 27.5% in 2013-2015. Compared to older patients, young patients were more likely to be Black (16.7% vs. 13.2%), Asian (7.6% vs. 6.1%) or Hispanic (15.5% vs. 7.7%), diagnosed with stage 4 disease (43.5% vs. 31.3%) and to have poorly differentiated grade (61% vs. 51.7%), p value < 0.0001 for all. For EC, 38,801 patients (27.8%) were under age 60. The proportion of patients diagnosed under 60, decreased over time: 29.6% in 2004-2006, 28.3% in 2007-2009, 27.6% in 2010-2012 and 26.2 % in 2013-2015. Compared to older patients, young patients were more likely to be Black (12.6% vs. 8.2%) or Hispanic (4.2% vs. 3.1%), diagnosed with stage 4 disease (34.3% vs. 26.1%), p value < 0.0001 for all. There was no difference in histologic grade between younger and older patients (41.1% vs. 40.3%, p = 0.85). Age < 60 years was associated with improved OS in both GC and EC. After adjusting for other demographic, socioeconomic, disease stage and treatment-related factors, Black patients had the worst median OS compared to other races in both malignancies as shown in the Table. Conclusions: Early-onset GC has increased over time while early-onset EC has decreased. Patients with early-onset gastric and esophageal cancer are more likely to be Black or Hispanic and to present with stage 4 cancer. Younger patients with GC are also more likely to have poorly differentiated histology. Most concerning, Black patients have the worst OS compared to other races for both GC and EC. [Table: see text]

20 Background: The incidence of colorectal cancer (CRC) in patients under age 50 is rising for reasons that are incompletely understood. We examined the effects of health disparities and socioeconomic factors on outcomes for patients with early-onset CRC compared to older-onset CRC. Methods: Patients with CRC from 2004-2015 in the National Cancer Database were included and categorized by age under or over 50 years. Differences in demographic, disease and treatment characteristics and socioeconomic factors between younger and older patients were assessed by Chi-square test. The effect of age, race, ethnicity, insurance status, community median income and community educational attainment on overall survival (OS) were assessed using Cox models. Subgroup analyses were carried out by factors with significant interactions with race. Bonferonni correction was used when indicated. Results: The study population comprised 1,061,204 patients, 108,058 (10.2%) of whom were under age 50. The proportion of patients diagnosed under age 50 increased over time: 9.4% in 2004-2006, 10.1% in 2007-2009, 10.5% in 2010-2012 and 10.7% in 2013-2015. Compared to older patients, young patients were more likely to be Black (15.1% vs. 11.3%) or Hispanic (8.6% vs. 4.6%) and to be diagnosed with stage 4 disease (24.9% vs. 17.0%), p < 0.0001 for all. Age < 50 years was associated with improved median OS (157.4 vs. 64.2 months, p < 0.0001). ). Black patients had the worst median OS (58.3 months) compared to White (67.0 months), Hispanic (91.6 months) or Asian (104.9 months) patients, p < 0.0001. Within the subgroup of early-onset CRC patients with private insurance, Blacks had worse OS compared to White patients at multiple community income and education levels. Older CRC patients did not demonstrate the same disparities. Asian and Hispanic patients had equivalent or better OS compared to White patients regardless of insurance type, income or education level. These data are shown in the Table. Conclusions: Early-onset CRC continues to increase. Patients with early-onset CRC are more likely to be Black or Hispanic and to present with stage 4 cancer compared to older patients. Alarmingly, Black patients showed worse OS compared to White patients in all income subgroups, even with private insurance. Much more work is needed to address the environmental factors and health disparities that lead to these outcomes. [Table: see text]

Abstract I ntroduction: Mycosis Fungoides (MF) is the most common subtype of cutaneous T-cell lymphomas. Prior Studies have identified Black race as a risk factor for earlier age at diagnosis, more advanced stages at time of diagnosis and poor prognosis in patients with MF. Data examining differences in racial disparities outcomes over time are limited. Objective: This retrospective analysis aims to examine if the racial disparities in survival outcomes of MF patients have improved over time. Subjects and Methods: Using the United States Surveillance, Epidemiology and End Results (SEER) 1988-2011 public use database, we examined survival patterns for patients with MF (with the code of 9700) between 1988 and 2011. Cases were divided into three cohorts based on the year of diagnosis; "1988 - 1995", "1996 - 2003", and "2004 - 2011". Univariable and multivariable analysis were conducted to assess for factors significantly associated with the overall survival. The nonparametric estimates of the survival distribution function, Kaplan and Meier survival curves, and Cox proportional hazards model were used to investigate the factors affecting the survival time. Results: From 1988 to 2011, a total of 2896 cases of MF were identified with a median follow-up of 60 months. The difference in the survival time between the years of diagnosis 1988-1995 and 2004-2011 is significant (p-value=0.05). The parameter estimate of the Cox proportional hazards model for the "1988-1995" and the "2004-2011" period as a reference is also significant (p-value = 0.024) and the hazard ratio (HR) is 1.407, which means that patients diagnosed in 1988-1995 were 1.4 times likely to die from the disease compared to the patients diagnosed in 2004-2011 (i.e. patients in 1988-1995 were more likely to not survive than in 2004-2011) (Table 1 and 2). There is no significant difference in the survival of the patients between "1996-2003" and "2004-2011" (p-value 0.998), Cox model estimate is not significant (p-value = 0.178), and the HR is 0.94 (Table 1 and 2). For the time period 1988-1995, the survival of Black patients was inferior to White (p= 0.0339), Asians (p=0.001), and other races (p=0.0011); Figure 2 and Table 3. For the time period 1996-2003, there was no difference in survival across races (p-value=0.7599); Figure 3 and Table 3. For the time period of 2004-2011, survival of Black patients was similar to White (p-value=1) but again inferior to Asian (p-value=0.05) and other races (p-value=0.09); Figure 4 and Table 3. Across the entire time period of 1998-2011, the survival of Black patients was inferior to White (Chi-square=6.59 and p-value=0.0084); Figure 5. The survival gap between Black and White patients seems to be obliterated in subsequent; "1996 - 2003" and "2004 - 2011" vs 1988-1995 (Figures 3 and 4) due to improvements in survival of Black patients over time (Figure 6) while the survival of White patients remained rather steady over time (Figure 7). Conclusions: Our study demonstrated that Black race was significantly correlated with poorer survival in patients with MF. The etiology of this poorer prognosis can be related to access to medical care, socioeconomic disparities, or possibly difference in disease biology and immune response. Despite the persistent pattern of lower survival across all time periods, the gap in survival between White and Black races seems to be narrowing overtime. Figure 1 Figure 1.

This study aimed to build up nomogram models to evaluate overall survival (OS) and cancer-specific survival (CSS) in early-onset esophageal cancer (EOEC). Patients diagnosed with esophageal cancer (EC) from 2004 to 2015 were extracted from the Surveillance Epidemiology and End Results (SEER) database. Clinicopathological characteristics of younger versus older patients were compared, and survival analysis was performed in both groups. Independent related factors influencing the prognosis of EOEC were identified by univariate and multivariate Cox analysis, which were incorporated to construct a nomogram. The predictive capability of the nomogram was estimated by the concordance index (C-index), calibration plot, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA). A total of 534 younger and 17,243 older patients were available from the SEER database. Younger patients were randomly segmented into a training set (n=266) and a validation set (n=268). In terms of the training set, the C-index of the OS nomogram was 0.740 (95% CI: 0.707-0.773), and that of the CSS nomogram was 0.752 (95% CI: 0.719-0.785). In view of the validation set, the C-index of OS and CSS were 0.706 (95% CI: 0.671-0.741) and 0.723 (95%CI: 0.690-0.756), respectively. Calibration curves demonstrated the consistent degree of fit between actual and predicted values in nomogram models. From the perspective of DCA, the nomogram models were more beneficial than the tumor-node-metastasis (TNM) and the SEER stage for EOEC. In brief, the nomogram model can be considered as an individualized quantitative tool to predict the prognosis of EOEC patients to assist clinicians in making treatment decisions.

e20019 Background: Multiple myeloma (MM) is a malignancy that affects Black Americans (BA) more often and at earlier age than White Americans (WA). BAs still frequently receive suboptimal care and are underrepresented in clinical trials or retrospective analyses. However, recent studies have shown that BA MM patients treated with standard-of-care regimens have similar if not superior outcomes than WA patients. The median age of MM diagnosis is 69 years; but ten percent of individuals develop MM before age of 50 years. Limited data are available regarding the outcomes and characteristics of this younger patient population. Herein, we specifically investigate the outcome of young MM patients. Methods: We retrospectively analyzed young MM patients (age < 50) diagnosed between 1992 and 2016 at The Ohio State University Comprehensive Cancer Center. After informed consent, data pertaining to patient demographics and MM characteristics were collected in a coded database. Descriptive statistics was used to summarize disease characteristics; chi-square or Wilcoxon rank-sum tests were used to compare outcomes between BA and WA patients. Overall Survival (OS) was estimated by Kaplan-Meier method, with log-rank test applied to test the statistical differences between survival curves. Two-sided p-values <0.05 were considered statistically significant. Results: In our institutional database, we identified 264 individuals who developed MM before age of 50 years (median age=46; range: 17-50 years). 211 of them had matched cytogenetic studies and were included in the final analysis. The majority of these patients were male (66%), had IgG disease (47%), and stage II-III at presentation (52%). 196 of patients (93%) underwent at least one autologous stem cell transplant-ASCT, with 23 of them receiving more than one ASCT (15%) and 9 of them undergoing allogeneic stem cell transplant (4%). In all, median OS was 9.84 years (95% CI, 6.75-12.92 years), which is higher than in unselected older MM patients. 24% of the patients (n=51) were BA while the remaining (n=160) were WA. We observed no statistical differences in terms of patient characteristics, disease stage, or cytogenetics between BA or WA, except for a statistically significant prevalence of del(13q) in WA patients (39% vs. 30%; p= 0.012). In our cohort, BA and WA patients received transplant at similar rates (94% vs. 88%, p-value=0.137). Finally, we observed an inferior median OS of 8.59 years (95% CI, 6.40-10.78 years) in WA compared with BA patients (median OS: not reached; p-value= 0.038), with 5-year OS of 86% in BA compared with 65% in WA patients. Conclusions: We report a retrospective cohort of young MM patients. In our cohort, we observed less prevalence of del(13q) and superior OS of BA compared with age-matched WA patients. This suggests that young BA MM patients benefit from standard-of-care approaches and strategies should continue to be pursued to improve access to care and optimize treatments.

Node Ratio

Background: Colorectal cancer is being diagnosed more frequently in the young and it presents in an advanced stage. In TNM staging, stage depends on tumor size and number of positive nodes, which depend on location of tumor as well as the extent of dissection.The lymph node ratio is regarded as a more reliable marker for prognosis. In this study, we compare epidemiology of colorectal cancer in the young (<40 years) and older patients as well as the LNR.Methods: Patients with colorectal cancer operated at the Tribhuvan University Teaching Hospital, Kathmandu, Nepal for a period of 4 years (2012 – 2016) were included in the study. Patients were grouped into young (≤ 40 years) and older (> 40 years) and clinic-pathological data such as site of lesion, clinical stage, and lymph node ratio were compared.Results: Of the 95 patients of colorectal cancer, 25 patients were of age ≤ 40 years (26%) and they had a higher median stage at diagnosis. In patients above 40 years, it was diagnosed at a relatively earlier stage. The mean number of positive nodes was 11.64 in younger patients whereas it was 18.34in those more than 40 years of age,but younger patients had higher lymph node ratio than elderly (0.31 vs 0.13) (P-value ≤ 0.005).Conclusions: Young patients with colorectal cancer tend to have more advanced disease. The lymph node metastasis and lymph node ratio tend to be higher in young patients.

Dietary Phosphate

Impaired phosphate excretion by the kidney leads to Hyperphosphatemia. It is an independent predictor of cardiovascular disease and mortality in patients with advanced chronic kidney disease (stage 4 and 5) particularly in case of dialysis. Phosphate retention develops early in chronic kidney disease (CKD) due to the reduction in the filtered phosphate load. Overt hyperphosphatemia develops when the estimated glomerular filtration rate (eGFR) falls below 25 to 40 mL/min/1.73 m2. Hyperphosphatemia is typically managed with oral phosphate binders in conjunction with dietary phosphate restriction. These drugs aim to decrease serum phosphate by binding ingested phosphorus in the gastrointestinal tract and its transformation to non-absorbable complexes [1].

Background: The incidence of pancreatic neuroendocrine tumors (PNETs) has increased significantly. The purpose of this study was to analyze the clinical characteristics and prognosis of patients under 50 years old. Methods: Patients with PNETs recorded in the Surveillance, Epidemiology, and End Results (SEER) database from 2004 to 2015 were analyzed. The clinical characteristics were analyzed by Chi-square test. The Kaplan-Meier method was used to estimate overall survival (OS). Multivariate Cox proportional risk regression analysis was used to determine independent prognostic factors. Results: 2,303 patients included, of which 547 (23.8%) patients were younger than 50 years old. The number of younger patients has increased steadily, while the proportion in total PNETs decreased recently. Compared with older group, the proportion of the Black, grade I/II, and surgery were higher in early-onset PNETs. Liver was the most frequent metastatic site. There was no significant difference in the incidence of different metastatic sites between younger and older PNETs patients, while younger patients had better OS (P < 0.05). Grade, N stage, M stage, and surgery were independent prognostic factors for OS in early-onset PNETs. Conclusions: Younger patients have unique clinicopathological characteristics compared with older patients in PNETs. Better OS was observed in younger patients which might due to the higher proportion of well-differentiated tumor and surgery than older patients.

AbstractOsteoporosis is a skeletal disorder with enhanced bone fragility, usually affecting the elderly. It is very rare in children and young adults and the definition is not only based on a low BMD (a Z-score < − 2.0 in growing children and a Z-score ≤ − 2.0 or a T-score ≤ − 2.5 in young adults) but also on the occurrence of fragility fractures and/or the existence of underlying chronic diseases or secondary factors such as use of glucocorticoids. In the absence of a known chronic disease, fragility fractures and low BMD should prompt extensive screening for secondary causes, which can be found in up to 90% of cases. When fragility fractures occur in childhood or young adulthood without an evident secondary cause, investigations should explore the possibility of an underlying monogenetic bone disease, where bone fragility is caused by a single variant in a gene that has a major role in the skeleton. Several monogenic forms relate to type I collagen, but other forms also exist. Loss-of-function variants in LRP5 and WNT1 may lead to early-onset osteoporosis. The X-chromosomal osteoporosis caused by PLS3 gene mutations affects especially males. Another recently discovered form relates to disturbed sphingolipid metabolism due to SGMS2 mutations, underscoring the complexity of molecular pathology in monogenic early-onset osteoporosis. Management of young patients consists of treatment of secondary factors, optimizing lifestyle factors including calcium and vitamin D and physical exercise. Treatment with bone-active medication should be discussed on a personalized basis, considering the severity of osteoporosis and underlying disease versus the absence of evidence on anti-fracture efficacy and potential harmful effects in pregnancy.

Background:The availability of biosimilars as non-proprietary versions of established biologic disease-modifying anti-rheumatic drugs (bDMARDs) is enabling greater access for patients with rheumatic diseases to effective medications at a lower cost. Since April 2017 both the originator and a biosimilar for etanercept (trade names Enbrel and Brenzys, respectively) have been available for use in Australia.Objectives:[1]To model effectiveness of etanercept originator or biosimilar in reducing Disease Activity Score 28-joint count C reactive protein (DAS28CRP) in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) or ankylosing spondylitis (AS) treated with either drug as first-line bDMARD[2]To describe persistence on etanercept originator or biosimilar as first-line bDMARD in patients with RA, PsA or ASMethods:Clinical data were obtained from the Optimising Patient outcomes in Australian rheumatoLogy (OPAL) dataset, derived from electronic medical records. Eligible patients with RA, PsA or AS who initiated etanercept originator (n=856) or biosimilar (n=477) as first-line bDMARD between 1 April 2017 and 31 December 2020 were identified. Propensity score matching was performed to select patients on originator (n=230) or biosimilar (n=136) with similar characteristics in terms of diagnosis, disease duration, joint count, age, sex and concomitant medications. Data on clinical outcomes were recorded at 3 months after baseline, and then at 6-monthly intervals. Outcomes data that were missing at a recorded visit were imputed.Effectiveness of the originator, relative to the biosimilar, for reducing DAS28CRP over time was modelled in the matched population using linear mixed models with both random intercepts and slopes to allow for individual heterogeneity, and weighting of individuals by inverse probability of treatment weights to ensure comparability between treatment groups. Time was modelled as a combination of linear, quadratic and cubic continuous variables.Persistence on the originator or biosimilar was analysed using survival analysis (log-rank test).Results:Reduction in DAS28CRP was associated with both time and etanercept originator treatment (Table 1). The conditional R-squared for the model was 0.31. The average predicted DAS28CRP at baseline, 3 months, 6 months, 9 months and 12 months were 4.0 and 4.4, 3.1 and 3.4, 2.6 and 2.8, 2.3 and 2.6, and 2.2 and 2.4 for the originator and biosimilar, respectively, indicating a clinically meaningful effect of time for patients on either drug and an additional modest improvement for patients on the originator.Median time to 50% of patients stopping treatment was 25.5 months for the originator and 24.1 months for the biosimilar (p=0.53). An adverse event was the reason for discontinuing treatment in 33 patients (14.5%) on the originator and 18 patients (12.9%) on the biosimilar.Conclusion:Analysis using a large national real-world dataset showed treatment with either the etanercept originator or the biosimilar was associated with a reduction in DAS28CRP over time, with the originator being associated with a further modest reduction in DAS28CRP that was not clinically significant. Persistence on treatment was not different between the two drugs.Table 1.Respondent characteristics.Fixed EffectEstimate95% Confidence Intervalp-valueTime (linear)0.900.89, 0.911.5e-63Time (quadratic)1.011.00, 1.011.3e-33Time (cubic)1.001.00, 1.007.1e-23Originator0.910.86, 0.960.0013Acknowledgements:The authors acknowledge the members of OPAL Rheumatology Ltd and their patients for providing clinical data for this study, and Software4Specialists Pty Ltd for providing the Audit4 platform.Supported in part by a research grant from Investigator-Initiated Studies Program of Merck & Co Inc, Kenilworth, NJ, USA.

Abstract Introduction Esophageal cancer (EC) is an aggressive malignancy with poor prognosis. Mortality and disease stage at diagnosis are important indicators of improvements in cancer prevention and control. We examined United States trends in esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC) mortality and stage at diagnosis by race and ethnicity. Methods We used Surveillance, Epidemiology, and End Results (SEER) data to identify individuals with histologically confirmed EAC and ESCC between 1 January 1992 and 31 December 2016. For both EAC and ESCC, we calculated age-adjusted mortality and the proportion presenting at each stage by race/ethnicity, sex, and year. We then calculated the annual percent change (APC) in each indicator by race/ethnicity and examined changes over time. Results The study included 19,257 EAC cases and 15,162 ESCC cases. EAC mortality increased significantly overall and in non-Hispanic Whites from 1993 to 2012 and from 1993 to 2010, respectively. EAC mortality continued to rise among non-Hispanic Blacks (NHB) (APC = 1.60, p = 0.01). NHB experienced the fastest decline in ESCC mortality (APC = − 4.53, p < 0.001) yet maintained the highest mortality at the end of the study period. Proportions of late stage disease increased overall by 18.5 and 24.5 percentage points for EAC and ESCC respectively; trends varied by race/ethnicity. Conclusion We found notable differences in trends in EAC and ESCC mortality and stage at diagnosis by race/ethnicity. Stage migration resulting from improvements in diagnosis and treatment may partially explain recent trends in disease stage at diagnosis. Future efforts should identify factors driving current esophageal cancer disparities.
