Abstract Background The overall survival of patients with multiple myeloma has been improved greatly over the last two decades with the advances of treatment. Several studies reported that this improvement in survival has been ascribed to the broader use of novel drugs and autologous tandem transplantation. However, there were still a certain portion of myeloma patients died early after diagnosis. We therefore aim to investigate the risk factors of early mortality (death within 60 days after diagnosis) in patients with multiple myeloma. Patients and Methods We included in this study 451 consecutive patients with multiple myeloma, newly diagnosed at an Asian tertiary medical center between January 1, 2002 and April 30, 2015. A total 57 subjects who developed early mortality were identified. Risk factors for early mortality in myeloma patients were collected and analyzed. Results Compared with non-early mortality myeloma patients, early mortality patients had higher probability of being male, primary plasma cell leukemia, low platelet count, low serum albumin, high corrected serum calcium, high serum creatinine, high LDH, high serum β2-microglobulin, poor performance status, and high ISS stage. With multivariate analysis, we found that male (adjusted OR 2.93, 95% CI 1.17-7.31), serum albumin < 3.5g/dl (adjusted OR 2.76, 95% CI 1.17-6.52), corrected serum calcium ≥ 12mg/dl (adjusted OR 3.56, 95% CI 1.47-8.63) and LDH ≥ 250U/L (adjusted OR 3.30, 95% CI 1.62-6.74) were significant risk factors of early mortality. Pneumonia represented as the leading cause of early mortality in myeloma patients (n = 18, 31.5%), followed by renal failure (n = 7, 12.2%). Conclusion Early mortality rate is high (12.6%) in patients with multiple myeloma. Patients of male gender, low serum albumin, high corrected serum calcium and LDH are at risk of early mortality. More than one third myeloma patients (21 out of 57) who developed early mortality are died of infection. Identifying the risk group and providing prompt intervention, such as prophylaxis antibiotics, may reduce the incidence rate of early mortality and improve the life expectancy of myeloma patients.

ObjectiveTo determine the prognostic values of histopathologic classification of myeloperoxidase-anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis and other clinical and laboratory features at the time of presentation on renal and patient survival associated with myeloperoxidase-ANCA-associated glomerulonephritis (MPO-ANCA-GN).MethodsA total of 112 patients diagnosed with MPO-ANCA-GN from October 2005 to December 2018 were enrolled. The baseline clinical characteristics, renal histopathological data, and risk factors predictive of renal and patient survival were retrospectively analyzed.ResultsAll 112 patients underwent renal biopsy. Disease in 32 patients was classified as focal, 26 as mixed, 29 as crescentic, and 25 as sclerotic. Over a median follow-up period of 41.5 months, there were 44 patients dialysis-dependent. The renal survival rate was significantly higher in the focal group than the other groups (p &lt; 0.001) and significantly lower in the sclerotic group (p &lt; 0.05). In addition, disease histopathologically classified as sclerotic (p = 0.044), high serum creatinine level (≥320 μmol/L, p &lt; 0.001), low albumin (&lt;30 g/L, p = 0.024) and hemoglobin level (&lt;90 g/L, p = 0.044) were associated with a greater risk of ESRD. After follow-up, 70 (62.5%) of 112 patients survived. Old age (≥60 years, p = 0.018) and low serum albumin (&lt;30 g/L, p = 0.006) was significant risk factor for patient survival.ConclusionAmong patients with MPO-ANCA-GN, those with poor renal function, disease histopathologically classified as sclerotic, and lower albumin and hemoglobin levels were risk factors for ESRD, while older age and low serum albumin level were associated with a greater risk for all-cause mortality.

The Difference

Abstract Background Risk of arterial (ATE) and venous thromboembolic events (VTE) is increased in multiple myeloma (MM). Immunomodulator therapy (Imid) concurrent with steroids further increases this risk. Retrospective single arm studies suggest that Asian patients with MM may have a lower risk of TE than in other ethnicities. We performed a retrospective study comparing Chinese (C) and African American (AA) patients in two centers, the Department of Clinical Oncology, Prince of Wales Hospital, the Chinese University of Hong Kong (PWH) and the University hospitals, Case Medical Center, Cleveland, Ohio (CMC), for ethnic differences in incidence of TE in MM. Methods 120 Chinese patients from PWH and 100 AA patients from CMC fulfilling IMWG consensus criteria for MM diagnosis between Jan 1st 2000 and Dec 31st 2011 were identified and selected for analysis. Data regarding demographics, comorbidities, myeloma characteristics, therapy and thrombotic complications were collected by electronic and paper chart review. Data collection was censored as of Dec 31st 2012. Results The Chinese cohort comprised more men, lower baseline incidence of diabetes (DM), hypertension (HTN) and non-myeloma related renal failure (CRF), advanced myeloma at diagnosis and more IgA subtype than AA. Over 90% of patients of both groups received chemotherapy. 72% of Chinese and 80% of AA received Imid based treatment. Lenalidomide with steroids was used more often in AA (36.8% AA vs 3.6%C, p<0.0001), Chinese received more thalidomide with steroids. (62.2% C vs 42.1%, p:0.004) Use of thromboprophylaxis (TP) is not routine in PWH, less Chinese were on TP during the disease course (11.7% vs 68%, p<0.0001) or during Imid based treatment. (16% vs 85%, p: 0.0001) Relative rates of aspirin, low molecular weight heparin and warfarin usage for TP were similar across both groups. Despite lower TP rates, a significantly lower rate of symptomatic VTE was observed in the Chinese. (3.3% vs 22%, p:0.001) The difference in VTE detection persisted on correction for number of imaging studies performed, 24 imaging tests in Chinese and 145 in AA. (16.7% vs 48.3%, p:0.004). Amongst the Chinese, all 4 events (100%) occurred on thalidomide dexamethasone (TD), 3 events (75%) in the absence of TP. In the AA, 21 of 26 events (81%) occurred on Imid based treatment. 12 events (46%) occurred in the absence of TP. On binary logistic regression using race, gender, prior venous thrombosis, any TP, TD and lenalidomide dexamethasone therapy as covariates, AA race (OR: 5.022, 95% CI:1.3- 19.4) and TD therapy (OR: 4.07, 1.26- 3.13) emerged as significant risk factors for VTE. Overall incidence of VTE on TD treatment was 4.5% in Chinese versus 22% in AA. (p:0.002) An increased number of arterial events were seen in the Chinese (9.2% vs 3% in AA) but the difference did not reach statistical significance. Of the 11 arterial events in Chinese, 5 (46%) occurred on Imid based therapy, 9 events (82%) were in the absence of TP. 7 were cardiac and 4 cerebrovascular. Of the 3 arterial events in AA, 1 (33.3%) occurred on Imids and all patients were receiving TP. 1 was cardiac, 1 abdominal and 1 upper limb. Conclusion Our study suggests that the Chinese have a lower risk of VTE than AA in the setting of MM. However , despite lower prevalence of most vascular risk factors in Chinese, ATE rates in Chinese were higher than AA, while not statistically significant. Larger studies are necessary to further elucidate these differences in thrombosis risk and to develop specific guidelines for TP in Asian patients with MM Disclosures: No relevant conflicts of interest to declare.

Abstract Monoclonal gammopathy of undetermined significance (MGUS) is the most common form of plasma cell dyscrasia, with a prevalence of 3% in the general population above age of fifty. MGUS has a malignant evolution rate of 1% per year. Large longitudinal studies have suggested that virtually all patients diagnosed with multiple myeloma (MM) had a preceding MGUS, with 75 % having detectible Monoclonal (M) protein ≥8 years prior to diagnosis. It is important to identify the features at diagnosis that can predict neoplastic transformation to MM. Purpose We identified 239 patients at our institute in whom MGUS was diagnosed between 2000 and 2010. The presenting clinico-hematologic features were correlated with the frequency of evolution into MM to identify early predictors of evolution. The primary end point was progression to MM. Results The patients' mean age was 70.7 years. The Male/Female ratio was 0.7. The mean concentration of the M component (MC) was 0.7 g/dL. IgG was the most frequent MC (77%), followed by IgA (13%). The median ratio of MC protein to total protein was 0.5. Single or multiple background polyclonal (PC) suppression was noted in 36% of patients. PC suppression of 50% or more was noted in 20.1% of patients, 49.8% had < 50% and 30.1% had no suppression. Mean bone marrow plasma cell percentage was 4.5 percent and mean hemoglobin was 12.4 g/dL. Eighteen of the 239 patients with MGUS progressed into MM over ten years of follow up. Univariate comparisons of all variables between those who progressed and those who did not, showed that the initial concentration of the serum M protein, ratio of M protein to the total protein, number of PC gamma globulins suppressed, degree of PC suppression and IgM gamma globulin suppression were statistically significant risk factors that correlated with progression into MM. Fourteen out of eighteen patients with progressive disease had either PC suppression or background IgM suppression. Conclusions Monoclonal protein concentration, ratio of M protein to the total protein and abnormal serum free light chain ratio are simple variables that have been shown in multiple previous studies to predict the progression of MGUS into MM. In our study, we additionally found that number of PC suppressed, degree of suppression and IgM suppression are also key risk factors that can predict progression. We believe that these variables can be potentially applied into an approach that uses a detailed risk stratification system to predict which cases of MGUS will progress into MM and to provide more intensive monitoring for patients more likely to progress.

Abstract Abstract 4254 Background: Invasive fungal infections (IFI) are a significant cause of morbidity and mortality in patients with acute myelogenous leukemia (AML) undergoing chemotherapy treatment. However, the epidemiology, risk factors, and outcomes of IFI in these patients have been poorly described. Methods: A single-center retrospective analysis was performed to study the epidemiology, risk factors, clinical outcomes, and mortality predictors of IFIs in AML patients undergoing intensive, multi-agent induction timed sequential therapy (TST) between January 2005 and June 2010. Newly diagnosed AML patients, with exception of acute promyelocytic leukemia, were studied. IFIs were defined using the European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG) criteria. Results: 254 consecutive patients (57% male; median age 54, range 20–78) were analyzed. 123 (48%) of patients had an IFI; of which, 15 patients (12%) had a proven candidal infection, and 108 patients (88%) had a mould infection (5 proven/probable (5%) and 103 (95%) possible mould infections). 237 (93%) patients received antifungal therapy during their treatment course (median day 8, range day -15 to 30). Of those, 63 (27%) received monotherapy (46% liposomal amphotericin, 44% voriconazole) and the rest received multiple antifungal agents. Significant risk factors and trends for developing +IFI shown from univariate analyses are listed in Table 1. Prolonged neutropenia, duration of mucositis, and concurrent bacterial infections did not significantly affect the development of +IFI. Using multivariate analyses, mortality was impacted by patients’ baseline organ function (p=0.002 [1.3,3.1]), specifically, by bilirubin < 2 mg/dL (p=0.003 [1.38,4.57]) and creatinine < 1.5 mg/dL (p=0.01 [1.23,5.4]). Patients with +IFI did not significantly impact overall survival. However, patients with candidal IFIs had a significantly lower overall survival compared to patients with mould IFIs and no IFI (HR 2.01 [1.06, 3.8]) (Figure 1). Candida colonization prior to or during the first week of chemotherapy, and development of mucositis were associated with the development of candidal IFIs (p=0.07). Conclusion: IFIs, particularly mould infections, remain a significant problem in patients with AML. Although overall survival did not appear to be significantly affected by mould infections, patients with candidal infections were more likely to die. Identification of risk factors for each type of IFIs may help to develop effective targeted preventive antifungal strategies. Disclosures: No relevant conflicts of interest to declare.

Objective: To explore the significance of the ratio of neutrophils to lymphocytes (NLR), monocytes to lymphocytes (MLR), and platelets to lymphocytes (PLR) in the prognosis of patients with newly diagnosed multiple myeloma. Methods: We retrospectively reviewed the data for 60 multiple myeloma patients who were diagnosed in Jiangning Hospital Affiliated to Nanjing Medical University from August 2011 to March 2020. According to NLR、MLR、PLR, the patients were divided into the low NLR group (NLR&lt;3.61) or high NLR group (NLR≥3.61), low MLR group (MLR&lt;0.33) or high MLR group (MLR ≥0.33), low PLR group (PLR&lt; 129.78) and high PLR group (PLR ≥129.78). Overall survival time (OS) was used as the prognostic evaluation criteria, and Kaplan-Meier survival curve, Log-rank test and Cox regression model were used to carry out univariate and multivariate analysis on clinical and laboratory parameters. Results: Among the 60 patients, 33 were male and 27 were female, the median age of onset was 65 years old, 19 were in the high NLR group, 41 were in the low NLR group, 24 were in the high MLR group, 36 were in the low MLR group, 26 were in the high PLR group, and 34 were in the low PLR group. The univariate analysis showed the prognosis was influenced by factors including NLR, PLR, age, ISS stages, hemoglobin (HGB), albumin (ALT). MLR, type of immunoglobulin, white globulin ratio (A/G), gender, β2-microglobulin, lactate dehydrogenase (LDH) and creatinine were not correlated with the total survival time of patients. The multivariate analysis showed that ISS III stages, PLR≥129.78、HGB&lt;100g/L were independent risk factors influencing the prognosis of MM patients. Conclusion: ISS III stages, PLR≥129.78、HGB&lt;100g/L are independent prognostic risk factors in newly diagnosed multiple myeloma patients, which can be used as an economical and effective method for early evaluation of patient prognosis.

AbstractIdentification of risk factors for early mortality (EM) in multiple myeloma (MM) patients may contribute to different therapeutic approaches in patients at risk for EM. This population-based study aimed to assess trends in EM and risk factors for EM among MM patients diagnosed in the Netherlands. All MM patients, newly diagnosed between 1989 and 2018, were identified in the Netherlands Cancer Registry. Patients were categorized into three calendar periods (1989–1998, 1999–2008, 2009–2018) and into five age groups (≤65, 66–70, 71–75, 76–80, >80 years). EM was defined as death by any cause ≤180 days post-diagnosis. We included 28,328 MM patients (median age 70 years; 55% males). EM decreased from 22% for patients diagnosed in 1989–1998 to 13% for patients diagnosed in 2009–2018 (P < 0.01) and this decrease was observed among all age groups. Exact causes of death could not be elucidated. Besides patient’s age, we found that features related to a more aggressive disease presentation, and patient characteristics reflecting patients’ physical condition were predictive of EM. In summary, EM decreased from 1999 onwards. Nevertheless, EM remains high, especially for patients aged >70 years. Therefore, novel strategies should be explored to improve the outcome of patients at risk for EM.

Chromosome 1Q21

Abstract Bortezomib is an active agent for treatment of multiple myeloma (MM) and may even be effective in patients (pts) with adverse prognostic factors including unfavorable cytogenetic abnormalities. However, it is unknown whether or not bortezomib may overcome the negative prognostic impact of a CKS1B gene amplification at chromosome 1q21 (amp1q21), which has recently been reported as a negative prognostic factor even in the setting of a total therapy approach. We therefore evaluated chromosome 1q21 among other abnormalities in 46 pts with relapsed/refractory MM who were treated with single-agent bortezomib (1.3 mg/m2 on days 1, 4, 8, and 11 every 3 weeks). Median age of pts was 63 years (range, 40 – 82 ) and median time to bortezomib therapy was 40 months (median number of prior therapies: 3; 96% of pts had high-dose pulsed dexamethasone, 61% thalidomide, 85% alkylating agents, and 41% high-dose melphalan). A response to bortezomib was noted in 45% of pts, with 17% of pts achieving a CR/near CR. Amp1q21 as determined by interphase FISH was observed in 20 of the 46 pts (43.5%). Treatment outcome after bortezomib was negatively affected by presence of amp1q21: The overall response rate was 30% (versus 58% in pts with normal 1q21; P = .06) and the CR/near-CR rate was 10% (versus 23%). Moreover, amp1q21 was associated with shortened time to treatment failure (median, 2.4 versus 6.6 months; P = .043) and overall survival (OS) (median, 4.4 versus 19.8 months; P = .003) compared to pts with normal 1q21. Beta-2-microglobulin and 14q32 translocations were unrelated to treatment outcome with bortezomib. In contrast, median OS was short in the presence of low serum albumin (4.8 versus 17.8 months; P = .036) and deletion of 13q14 (6.7 months versus median not yet reached; P = .06). Using amp1q21, low serum albumin, and deletion of 13q14 as risk factors, patients with significantly different median OS after bortezomib treatment were discriminated: Pts with ≥ 2 risk factors had a median OS of only 4.9 months as opposed to pts with 1 risk factor (median OS 16.5 months) or without any risk factor (median OS not yet reached) (P = .004). In conclusion, FISH-defined amp1q21 is a strong adverse prognostic factor for pts with relapsed/refractory MM treated with single-agent bortezomib. We are currently investigating whether or not bortezomib combinations may be more effective in MM pts with amp1q21.

AbstractBackgroundHypertriglyceridemia has arisen as the third leading cause of acute pancreatitis. This study aimed at exploring the association between the severity of hypertriglyceridemia-induced pancreatitis (HTGP) and computed tomography (CT)-based body composition parameters and laboratory markers.MethodsLaboratory and clinical parameters were collected from 242 patients with HTGP between 2017 and 2020. Severity of HTGP was evaluated by original or modified CT severity index. Body composition parameters such as area and radiodensity of muscle, subcutaneous adipose tissue and visceral adipose tissue were calculated by CT at the level of third lumbar vertebra. Parameters were compared between mild and moderately severe to severe HTGP. Uni-variate and multi-variate Logistic regression analyses were employed to assess the risk factors of the severity of HTGP.ResultsSeventy patients (28.9%) presented with mild HTGP. Body mass index, waist circumference and all CT-based body composition parameters differed between male and female patients. None was associated with the severity of HTGP, neither in males nor in females. Receiver operating characteristic curves showed that areas under the curves of apolipoprotein A-I and albumin to predict the severity of HTGP were 0.786 and 0.759, respectively (allP < 0.001). Uni-variate and further multi-variate Logistic regression analysis confirmed that low serum albumin (< 35 g/L,P = 0.004, OR = 3.362, 95%CI = 1.492–8.823) and apolipoprotein A-I (< 1.1 g/L,P < 0.001, OR = 5.126, 95%CI = 2.348–11.195), as well as high C-reactive protein (> 90 mg/L,P = 0.005, OR = 3.061, 95%CI = 1.407–6.659) and lipase (P = 0.033, OR = 2.283, 95%CI = 1.070–4.873) were risk factors of moderately severe to severe HTGP. Levels of albumin, apolipoprotein A-I, C-reactive protein and lipase were also associated with the length of hospital stay (allP < 0.05). Besides, low serum albumin, low-density lipoprotein cholesterol and high radiodensity of subcutaneous adipose tissue were significant risk factors of pancreatic necrosis in patients with HTGP (allP < 0.05).ConclusionsLow serum albumin and apolipoprotein A-I, and high C-reactive protein and lipase upon admission were associated with a more severe type of HTGP and longer hospital stay for these patients. Albumin and apolipoprotein A-I may serve as novel biomarkers for the severity of HTGP. However, none of the body composition parameters was associated with the severity of HTGP.

Objectives: Differences in the mechanisms of subtrochanteric and diaphyseal atypical femoral fractures (AFFs) have been speculated in studies that have analyzed differences in the patients’ backgrounds. However, the etiologies of each type of AFF have not been investigated in detail. Therefore, this study aimed to investigate the nature and etiologies of the risk factors for diaphyseal AFFs. Materials and Methods: Eighty consecutive Japanese patients with 91 diaphyseal AFFs (the AFF group) and 110 age-matched female patients with osteoporosis (the non-AFF control group) were included. Their clinical data were compared and the factors affecting AFFs were investigated. Furthermore, the etiologies of the risk factors for diaphyseal AFFs were examined. Results: Multivariate analysis revealed that femoral serrated changes, bisphosphonate or denosumab usage, and lateral and anterior femoral curvatures were the risk factors for diaphyseal AFFs (p<0.0011, p=0.0137, and p<0.0001, respectively). Multivariate analyses also revealed that serrated changes and low serum 25(OH)D levels affected the lateral curvature (p=0.0088 and 0.0205, respectively), while serrated changes affected the anterior curvature (p=0.0006); each significantly affected the femoral curvature. In addition, a high serum calcium (Ca) level, lateral femoral curvature, and anterior femoral curvature were the predictors of serrated changes (p=0.0146, 0.0002, and 0.0098, respectively). Conclusion: The risk factors for diaphyseal AFFs were bone resorption inhibitor usage, a strong femoral curvature, and serrated changes. A low serum 25(OH)D level and serrated changes are the risk factors for lateral curvature, while a high serum Ca level is a risk factor for serrated changes.
