ABSTRACT Background Adipose tissue radiodensity may have prognostic importance for colorectal cancer (CRC) survival. Lower radiodensity is indicative of larger adipocytes, while higher radiodensity may represent adipocyte atrophy, inflammation, or edema. Objectives We investigated associations of adipose tissue radiodensity and longitudinal changes in adipose tissue radiodensity with mortality among patients with nonmetastatic CRC. Methods In 3023 patients with stage I–III CRC, radiodensities of visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) were quantified from diagnostic computed tomography (CT) images. There were 1775 patients with follow-up images available. Cox proportional hazards models and restricted cubic splines were used to examine associations of at-diagnosis values and of longitudinal changes in VAT and SAT radiodensities with risks of death after adjusting for potential confounders, including body size and comorbidities. Results VAT and SAT radiodensities were linearly associated with all-cause mortality: the HRs for death per SD increase were 1.21 (95% CI, 1.11–1.32) for VAT radiodensity and 1.18 (95% CI, 1.11–1.26) for SAT radiodensity. Changes in adipose tissue radiodensity had curvilinear associations with risks of death. The HR for an increase in VAT radiodensity of at least 1 SD was 1.53 (95% CI, 1.23–1.90), while the HR for a decrease of at least 1 SD was nonsignificant at 1.11 (95% CI, 0.84–1.47) compared with maintaining radiodensity within 1 SD of baseline. Similarly, increases (HR, 1.88; 95% CI, 1.48–2.40) but not decreases (HR, 1.20; 95% CI, 0.94–1.54) in SAT radiodensity significantly increased the risk of death compared with no change in radiodensity. Conclusions In patients with nonmetastatic CRC, adipose tissue radiodensity is a novel risk factor for total mortality that is independent of BMI and changes in body weight.

Background: HbA1c is the standard measure to monitor glucose control and is now used for diagnosis of diabetes. Fructosamine and glycated albumin are markers of short-term glycemic control that may add complementary information to HbA1c. However, the associations of fructosamine and glycated albumin with cardiovascular outcomes are uncharacterized. Methods: We measured glycated albumin and fructosamine in 11104 adult participants (792 with a history of diabetes) of the community-based ARIC Study without cardiovascular disease at baseline (1990-1992). We evaluated the associations of fructosamine and glycated albumin with incident coronary heart disease and total mortality. We compared these associations to those for HbA1c. Results: Baseline HbA1c was highly correlated with fructosamine (Pearson’s r =0.82) and glycated albumin (Pearson’s r=0.86). During over two decades of follow-up there were 1,032 new cases of coronary heart disease and 2,594 deaths. In Cox proportional hazards models adjusted for traditional cardiovascular risk factors, elevated baseline levels of fructosamine and glycated albumin were significantly associated with coronary heart disease and total mortality ( Figure ). After additional adjustment for HbA1c, the associations were attenuated but remained significant, particularly at diabetic levels of fructosamine and glycated albumin. The associations with death were J-shaped, with an elevation of risk also apparent at the lowest levels of each biomarker, as has been previously observed for HbA1c. Conclusions: The acceptance of new measures of hyperglycemia is partly dependent on establishing their association with long-term outcomes. We found that fructosamine and glycated albumin were associated with coronary heart disease and mortality and that these associations were similar to those observed for HbA1c. The elevated risk of death at very low levels of fructosamine, glycated albumin, and HbA1c deserves further examination.

Background and objectivesIncreased circulating galactose-deficient IgA1 and subsequently complement activation both play important roles in the pathophysiology of IgA nephropathy. However, their relationship to disease severity and progression remains unclear.Design, setting, participants, & measurementsWe assessed 1210 participants in a cohort study of biopsy-proven IgA nephropathy at Peking University First Hospital. Plasma concentrations of galactose-deficient IgA1 and complement component C3 were measured at the time of biopsy. We tested associations of galactose-deficient IgA1 and galactose-deficient IgA1/C3 ratio with CKD progression event, defined as ESKD or 50% decline in eGFR, using Cox proportional hazards models and restricted cubic splines.ResultsAfter a median follow-up of 43 months (interquartile range, 24–76 months), 172 (14%) participants reached the CKD progression event. The association of galactose-deficient IgA1 levels and CKD progression event showed a nonlinear relationship. The risk of CKD progression events was greater with higher plasma galactose-deficient IgA1 levels but reached a plateau when galactose-deficient IgA1>325 U/ml, whereas the risk of CKD progression events monotonically increased with higher galactose-deficient IgA1/C3 ratio. After adjustment for traditional risk factors (demographics, eGFR, proteinuria, hypertension, Oxford pathologic score, and corticosteroids/immunosuppressive therapy), higher levels of galactose-deficient IgA1/C3 ratio were independently associated with CKD progression event (per natural log-transformed [galactose-deficient IgA1/C3], hazard ratio, 2.03; 95% confidence interval [95% CI], 1.25 to 3.29; P=0.004). In reference to the first quartile of the galactose-deficient IgA1/C3 ratio, hazard ratios were 1.71 (95% CI, 1.01 to 2.89) for the second quartile, 1.55 (95% CI, 0.91 to 2.63) for the third quartile, and 2.17 (95% CI, 1.33 to 3.56) for the fourth quartile.ConclusionsIn IgA nephropathy, plasma galactose-deficient IgA1/C3 ratio was associated with CKD progression event independent of clinical and biopsy characteristics.

4048 Background: NCCN guidelines recommend assessment of =12 lymph nodes (LN) to improve accuracy in colorectal cancer (CRC) staging. Previous studies have used various cut-points to assess the relationship between the number of LN sampled and survival. The association between NCCN guideline-compliant nodal sampling and survival is assessed, while controlling for other risk factors. Methods: We selected 145,485 adult patients newly diagnosed with stage II or III from SEER during 1990–2003. Kaplan-Meier curves were compared using the log-rank test. Cox proportional hazards models were constructed to determine the effect of sampling ≥ 12 LN on survival. Results: Median patient follow-up was 5.7 years. The table shows overall survival rates in CRC patients with < 12 versus =12 LN assessed: After adjusting for age, sex, tumor size and grade, sampling ≥ 12 LN was independently associated with improved survival. For patients with =12 versus <12 LN assessed, survival increased by 13% for stage IIa [HR=0.75; 95%CI 0.72–0.78; p< .001], 16% for stage IIb [HR=0.69; 95%CI 0.67- 0.71; p< .001], 12% for stage IIIb [HR=0.75; 95%CI 0.72–0.77], and 10% for stage IIIc [HR=0.85, 95%CI 0.81–0.89]. The association was not statistically significant for stage IIIa patients. Conclusion: Consistent with previous reports, this analysis found that optimal nodal sampling increased survival across stage II and III, specifically when ≥ 12 LN are sampled and when controlling for other risk factors. Furthermore, the results underscore the need for adhering to the NCCN guidelines. The lack of a statistically significant association in stage IIIa patients may be due to small cohort size.

240 Background: In 15-30% of pts with metastatic PCa who progress on Maximal Androgen Blockade (MAB), withdrawal of the antiandrogen agent (AAWD) and continuing the LHRH agonist alone, leads to PSA decreases of ≥50% and prolonged progression free survival. Here we describe patient and disease characteristics, treatment history and outcomes of pts who have been managed with AAWD. Methods: Data were obtained from SA-PCCOC (a longitudinal, observational registry of biopsy-proven PCa cases, throughout the Australian state of South Australia since 1998). Proportions were compared using a Chi squared test. A multivariable model used competing risks (Fine and Gray) and Cox proportional Hazards models to assess overall survival and Prostate cancer specific mortality (PCSM). Survival was calculated from the date of rising PSA for patients on LHRH and AA. Results: 140 pts were found to have MAB. Of these, 31(22.1%) had AAWD. In the AAWD group, median age was 81y (51-95). Age at diagnosis, Gleason score at biopsy and diagnostic PSA were not significantly different amongst the two groups. Treatment PSA was significantly lower in the AAWD group (20.55 (range 0.6-9,995) vs 50.50 (range 0.95-4378) p= 0.02). There was a significant association of AAWD with PCSM (sHR 0.35, 95% CI 0.16-0.76; p = 0.008). Also significant in the model was prior time on hormones (sHR [per month increase] 0.96 95% CI 0.95-0.98, p<0.001). There was also a significant association of AAWD with overall survival (HR 0.22, 95% CI 0.10-0.46; p <0.001). Again, prior time on hormones was also significant (HR [per month increase] 0.96 95% CI 0.95-0.98, p<0.001). Multivariate analysis was performed on data from 80 pts (60 pts omitted due to missing data). Conclusions: Pts in whom AAWD was used were older and had lower treatment PSA. In this small cohort, AAWD was associated with both reduced PCSM and overall risk of death. The time spent on MAB also appeared to be significant. This retrospective observational study may be subject to confounding, however the observation warrants further investigation in larger cohorts and in a prospective setting.

Ctp Score

e16659 Background: Child-Turcotte-Pugh (CTP) score is widely used in the assessment of prognosis of HCC and CTP-A is the standard criterion for active therapy and clinical trials entry. Recently, ALBI and insulin-like growth factor-1 (IGF)-CTP scores have been reported to improve survival prediction over CTP score. However, comparative studies to compare both scores and to integrate IGF into Albi score are lacking. Methods: After institutional board approval, data and samples were prospectively collected. 299 HCC patients who had data to generate both IGF-CPG and Albi index were used. The ALBI index, and IGF score were calculated, Cox proportional hazards models were fitted to evaluation the association between overall survival (OS) and CTP, IGF-CTP, Albi and IGF, albumin, bilirubin. Harrell’s Concordance index (C-index) was calculated to evaluate the ability of the three score system to predict overall survival. And the U-statistics was used to compare the performance of prediction of OS between the score system. Results: OS association with CTP, IGF-CTP and Albi was performed (Table). IGF-CTP B was associated with a higher risk of death than A (HR = 1.6087, 95% CI: 1.2039, 2.1497, p = 0.0013), ALBI grade 2 was also associated with a higher risk of death than 1 (HR = 2.2817, 95% CI: 1.7255, 3.0172, p < 0.0001). IGF-1(analyzed as categorical variable) was independently associated with OS after adjusting for the effects of ALBI grade. Which showed IGF-1 ≤26 was significantly associated with poor OS, P = 0.001. Conclusions: Although ALBI grade and IGF-CTP score in this analysis had similar prognostic values in most cases, their benefits might be heterogenous in some specific conditions. We looked into corporation of IGF-1 into ALBI grade, IGF score with cutoff ≤26 which clearly refined OS prediction and better OS stratification of ALBI-grade.

e19114 Background: National cancer registries are valuable tools used to analyze patterns of care and clinical oncology outcomes; yet, patients with missing data may impact the accuracy and generalizability of these data. We sought to evaluate the association between missing data and overall survival (OS). Methods: Using the NCDB and SEER, we compared data missingness among patients diagnosed with invasive breast cancer from 2010-2014. Key variables included: demographic variables (age, race, ethnicity, insurance, education, income), tumor variables (grade, ER, PR, HER2, TNM stage), and treatment variables (surgery in both databases; chemotherapy and radiation in NCDB). OS was compared between those with and without missing data via Cox proportional hazards models. Results: Overall, 775,996 patients in the NCDB and 263,016 in SEER were identified; missingness of at least 1 key variable was 29% and 13%, respectively. Of those, the majority were missing a tumor variable (NCDB 80%; SEER 88%), while demographic and treatment variables were missing less often. When compared to patients with complete data, missingness was associated with a greater risk of death; NCDB 17% vs. 14% (HR 1.23, 99% CI 1.21-1.25) and SEER 27% vs 14% (HR 2.11, 99% CI 2.05-2.18). Rate of death was similar whether the patient was missing 1 or ≥2 variables. When stratified by the type of missing variable, differences in OS between those with and without missing data in the NCDB were small. In SEER, reductions in OS were largest for those missing tumor variables (HR 2.26, 99% CI 2.19-2.33) or surgery data (HR 3.84, 99% CI 3.32-4.45). Among the tumor variables specifically, few clinically meaningful differences in OS were noted in the NCDB, while the most significant differences in SEER were noted in T and N stage (table). Conclusions: Missingness of select variables is associated with a worse OS and is not uncommon within large national cancer registries. Therefore, researchers must use caution when choosing inclusion/exclusion criteria for outcomes studies. Future research is needed to elucidate which patients are most often missing data and why OS differences are observed. [Table: see text]

Purpose Previous studies have suggested that higher plasma 25-hydroxyvitamin D3 [25(OH)D] levels are associated with decreased colorectal cancer risk and improved survival, but the prevalence of vitamin D deficiency in advanced colorectal cancer and its influence on outcomes are unknown. Patients and Methods We prospectively measured plasma 25(OH)D levels in 515 patients with stage IV colorectal cancer participating in a randomized trial of chemotherapy. Vitamin D deficiency was defined as 25(OH)D lower than 20 ng/mL, insufficiency as 20 to 29 ng/mL, and sufficiency as ≥ 30 ng/mL. We examined the association between baseline 25(OH)D level and selected patient characteristics. Cox proportional hazards models were used to calculate hazard ratios (HR) for death, disease progression, and tumor response, adjusted for prognostic factors. Results Among 515 eligible patients, 50% of the study population was vitamin D deficient, and 82% were vitamin D insufficient. Plasma 25(OH)D levels were lower in black patients compared to white patients and patients of other race (median, 10.7 v 21.1 v 19.3 ng/mL, respectively; P < .001), and females compared to males (median, 18.3 v 21.7 ng/mL, respectively; P = .0005). Baseline plasma 25(OH)D levels were not associated with patient outcome, although given the distribution of plasma levels in this cohort, statistical power for survival analyses were limited. Conclusion Vitamin D deficiency is highly prevalent among patients with stage IV colorectal cancer receiving first-line chemotherapy, particularly in black and female patients.

Background: Survival is reduced in African–Americans (AAs) diagnosed with colorectal cancer (CRC), especially in those <50 years old, when compared with Caucasian Americans (CAs). Yet, the role of clinicopathologic features of CRCs on racial differences in survival needs further study. Materials & methods: Over 1000 individuals (CA 709, AA 320) diagnosed with CRC were studied for survival via the Cox proportional hazards regression analysis based on race and risk of death in two age groups (<50 or 50+). Results: Risk of death for younger AAs (<50) was elevated compared with younger CAs (hazard ratio [HR] 1.98 [1.26–3.09]). Yet no racial differences in survival was observed in older cohort (50+ years), HR 1.07 (0.88–1.31); p for interaction = 0.01. In younger AAs versus CAs only, colonic location attenuated the risk of death. Conclusion: The tumor location and histology influence the poorer survival observed in younger AAs suggesting these may also influence treatment responses.

Background: Policymakers need robust data to respond to the COVID-19 pandemic. We describe demographic features, treatments and clinical outcomes in the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) COVID-19 cohort, the world's largest international, standardised cohort of hospitalised patients. Methods: The dataset analysed includes COVID-19 patients hospitalised between January 2020 and May 2021. We investigated how symptoms on admission, comorbidities, risk factors, and treatments varied by age, sex, and other characteristics. We used Cox proportional hazards models to investigate associations between demographics, symptoms, comorbidities, and other factors with risk of death, admission to intensive care unit (ICU), and invasive mechanical ventilation (IMV). Findings: 439,922 patients with laboratory-confirmed (91.7%) or clinically-diagnosed (8.3%) SARS-CoV-2 infection from 49 countries were enrolled. Age (adjusted hazard ratio [HR] per 10 years 1.49 [95% CI 1.49-1.50]) and male sex (1.26 [1.24-1.28]) were associated with a higher risk of death. Rates of admission to ICU and use of IMV increased with age up to age 60, then dropped. Symptoms, comorbidities, and treatments varied by age and had varied associations with clinical outcomes. Tuberculosis was associated with an 86% higher risk of death, and HIV with an 87% higher risk of death. Case fatality ratio varied by country partly due to differences in the clinical characteristics of recruited patients. Interpretation: The size of our international database and the standardized data collection method makes this study a reliable and comprehensive international description of COVID-19 clinical features. This is a viable model to be applied to future epidemics.

Abstract ObjectivesWe expected to explore the associations of hearing loss and hearing thresholds at different frequencies with total and cause-specific mortality.Methods11,732 individuals derived from the National Health and Nutrition Examination Survey (NHANES) 1999-2012 were included in this study. Data of death was extracted from the NHANES Public-Use Linked Mortality File through December 31, 2015. Cox proportional hazards models were used to explore the associations between hearing loss, hearing thresholds at different frequencies and total or cause-specific mortality. ResultsA total of 1,253 deaths occurred with a median follow-up of 12.15 years. A significant positive dose-response relationship between hearing loss in speech frequency and total mortality was observed, and the HRs and 95% CIs were 1.16 (0.91, 1.47), 1.54 (1.19, 2.00) and 1.85 (1.36, 2.50), respectively for mild, moderate and severe speech-frequency hearing loss (SFHL) with a P trend of 0.0003. In addition, moderate (HR: 1.90, 95%CI: 1.20-3.00) and greater (3.50, 1.38-8.86) SFHL significantly elevated risk of heart disease mortality. Moreover, hearing thresholds of >25 dB at 500, 1000, or 2000 Hz were significantly associated with elevated mortality from all causes (1.40, 1.17-1.68; 1.44, 1.20-1.73; and 1.33, 1.10-1.62, respectively) and heart disease (1.89, 1.08-3.34; 1.95, 1.21-3.16; and 1.89, 1.16-3.09, respectively). ConclusionHearing loss is associated with increased risks of total mortality and heart disease mortality, especially for hearing loss at speech frequency. Preventing or inhibiting the pathogenic factors of hearing loss is important for reducing the risk of death.
