The Impact

Introduction: The impact of obesity on survival outcomes in patients with glioblastoma (GBM) has not been well reported and the results for patients are currently unclear. We investigated the effect of obesity on survival outcomes in patients with newly diagnosed GBM. Methods: Using electronic medical records, all GBM patients that visited the Seoul St. Mary’s Hospital between 2008 and 2018 were reviewed. A total of 177 patients met our eligibility criteria. The cut-off point for BMI was 23.0 kg/m2 based on previous studies which focused on Asian populations. Results: A total of 177 patients met our eligibility criteria. The overall median BMI of patients was 24.5 kg/m2 (range 15.82-39.26). About 62 patients who had a BMI less than the cut-off value were assigned to the “lower BMI” group, while 115 patients who had a BMI greater than the cut-off value were assigned to the “higher BMI” group. In Kaplan-Meier survival analysis, the median OS of the higher BMI group was longer than that of the lower BMI group (21.3 months vs 15.3 months, P = .002). In multivariate Cox regression analysis for OS, lower BMI was associated with inferior OS (HR 1.48 CI 1.06-2.08, P = .002). Conclusion: Our findings suggest that elevated BMI may be associated with better survival in patients with newly diagnosed GBM. Additional larger prospective studies could help validate our findings to confirm the effect of body composition and survival outcomes in GBM patients.

Background: This study assessed the patterns of opioid use among patients with advanced gastrointestinal cancers who were included in 8 clinical trials and evaluated the impact of opioid use on survival outcomes of included patients. Methods: Deidentified datasets from 8 clinical trials evaluating first-line systemic treatment of advanced gastrointestinal cancers were accessed from the Project Data Sphere platform (ClinicalTrial.gov identifiers: NCT01124786, NCT00844649, NCT00290966, NCT00678535, NCT00699374, NCT00272051, NCT00305188, and NCT00384176). These trials evaluated patients with pancreatic carcinoma, gastric carcinoma, hepatocellular carcinoma (HCC), and colorectal carcinoma. Multivariable logistic regression analysis was used to evaluate factors predicting the use of opioids. Kaplan-Meier survival estimates were used to compare survival outcomes in each disease entity among patients who did or did not receive opioid treatment. Multivariable Cox regression analysis was then used to further assess the impact of opioid use on survival outcomes in each disease entity. Results: A total of 3,441 participants were included in the current analysis. The following factors predicted a higher probability of opioid use within logistic regression analysis: younger age at diagnosis (odds ratio [OR], 0.990; 95% CI, 0.984–0.997; P=.004), nonwhite race (OR for white vs nonwhite, 0.749; 95% CI, 0.600–0.933; P=.010), higher ECOG score (OR for 1 vs 0, 1.751; 95% CI, 1.490–2.058; P<.001), and pancreatic primary site (OR for colorectal vs pancreatic, 0.241; 95% CI, 0.198–0.295; P<.001). Use of opioids was consistently associated with worse overall survival (OS) in Kaplan-Meier survival estimates of each disease entity (P=.008 for pancreatic cancer; P<.001 for gastric cancer, HCC, and colorectal cancer). In multivariable Cox regression analysis, opioid use was associated with worse OS among patients with pancreatic cancer (hazard ratio [HR], 1.245; 95% CI, 1.063–1.459; P=.007), gastric cancer (HR, 1.725; 95% CI, 1.403–2.122; P<.001), HCC (HR, 1.841; 95% CI, 1.480–2.290; P<.001), and colorectal cancer (HR, 1.651; 95% CI, 1.380–1.975; P<.001). Conclusions: Study findings suggest that opioid use is consistently associated with worse OS among patients with different gastrointestinal cancers. Further studies are needed to understand the underlying mechanisms of this observation and its potential implications.

Objective: To assess the survival differences between cisplatin/etoposide versus carboplatin/etoposide chemotherapy regimens in the management of extra-pulmonary neuroendocrine carcinomas (NECs). Methods: Administrative cancer care databases in the province of Alberta, Canada were reviewed, and patients with extra-pulmonary NECs (including those with small cell and large cell neuroendocrine carcinomas) who were treated with either cisplatin/ etoposide or carboplatin/ etoposide, 2004-2019, were reviewed. Kaplan-Meier survival estimates were used to compare the survival outcomes according to the type of platinum agent, and multivariable Cox regression analysis was used to assess the impact of the type of platinum agent on overall survival outcomes. Results: A total of 263 eligible patients were included in this analysis. These include 176 patients who received cisplatin/ etoposide and 87 patients who received carboplatin/etoposide. Using Kaplan-Meier survival estimates, patients treated with cisplatin have better overall survival compared to patients treated with carboplatin (P=0.005). Multivariable Cox regression analysis suggested that the following factors were associated with worse overall survival: higher Charlson comorbidity index (HR: 1.17; 95% CI: 1.05-1.30), gastrointestinal primary site (HR: 1.55; 95% CI: 1.12-2.14), stage IV disease (HR: 1.75; 95% CI: 1.28-2.38) and use of carboplatin (HR: 1.40; 95% CI: 1.02-1.92). Conclusions: The current study suggested that cisplatin/etoposide might be associated with better overall survival compared to carboplatin/etoposide among patients with extra-pulmonary NECs. It is unclear if this is related to differences in inherent responsiveness to the two platinum agents, or due to differences in comorbidity burden between the two treatment groups.

Abstract Abstract 3600 Background: RBC transfusion dependency is a well known poor prognostic factor for patients with myelodysplastic syndromes, reflecting the underlying biology of disease and the impact of iron overload. To our knowledge, the impact of RBC transfusion (TX) on induction chemotherapy outcome in AML patients has not been investigated. Methods: Data were collected retrospectively in a cohort of newly diagnosed AML patients who received induction chemotherapy (3+ 7 regimen) at Moffitt Cancer Center. The primary objective of this study was to examine the relationship between number of RBC transfused units during first induction chemotherapy and outcome. Number of RBC units transfused only during the first cycle of induction were collected, and patients were divided into 2 groups, < 10 units RBC or ≥ 10 RBC units. All analyses were conducted using SPSS version 19.0. The Kaplan–Meier method was used to estimate median overall survival; chi-square test was used for comparison of categorical variables and t -test for continuous variables. Log rank test was used to compare Kaplan–Meier survival estimates between two groups and Cox regression for multivariable analysis. Results: 135 AML patients who received 3+7 induction chemotherapy were included in this analysis. The median number of RBC units transfused during first induction chemotherapy was 10.0. Fifty nine patients received less than 10 units and 76 patients received 10 or more RBC units. Baseline characteristics were similar between patients with RBC units < 10 and those who received ≥ 10 units with respect to age, sex, history of antecedent MDS, karyotype, double induction requirement, and remission rates. (Table-1) The median OS for patients who received < 10 units was 538 days (95%CI 199.3–876.7) compared to 296 days (95%CI 234–358) for patients who received ≥ 10 RBC (P=0.001). (Figure 1) The impact of RBC TX was greater in younger patients (< 60 years), for whom median OS was 798 days compared to 275 days in patients who had < 10 and ≥ 10 RBC units respectively, (p=0.013). In patients ≥ 60 years, the median OS was 275 days compared to 240 days for patients who had < 10 and ≥ 10 RBC units respectively, (p=0.06). Relapse rate was 52.5% (n=31) for patients who received < 10 units compared to 39.5% (n=30) in those who received ≥ 10 RBC units (p=0.09). In a multivariable Cox regression analysis including age ≥ 60 years, karyotype, achieving remission (CR/CRi), receiving double induction, and RBC transfusion ≥ 10 units; age≥ 60 years [HR 1.5 (95%CI 1.0–2.2), p=0.047], karyotype [HR 1.7 (95%CI 1.3–2.3), P<0.005], and CR/CRi [HR 3.7 (95%CI 2.3–6.0), p<0.005], RBC≥ 10 units [Hazard ratio 1.8 (95%CI 1.2–2.7,p=0.006) were independent prognostic variables for OS. Conclusion: To our knowledge, this is the first study to identify a relationship between induction outcome and number of RBC units transfused (≥ 10 units) in AML patients. We hypothesize that requirement for RBC transfusion may reflect underlying disease biology, relative resistance to intensive chemotherapy or may lead to iron overload. These findings warrant confirmation in a larger, prospective study. Disclosures: No relevant conflicts of interest to declare.

Abstract Background Whether anesthesia type is associate with the surgical outcome of Hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) remains to be determined. This study aims to investigate the impact of volatile inhalational anesthesia (INHA) versus total IV anesthesia (TIVA) on the survival outcomes in HCC patients with PVTT. Methods A cohort of in-patients whom were diagnosed of HCC with PVTT in Eastern Hepatobiliary Surgery Hospital, Shanghai, China, from January 1, 2008 to December 24, 2012 were identified. Surgical patients receiving the INHA and TIVA were screened out. The overall survival (OS), recurrence-free survival (RFS) and several postoperative adverse events were compared according to anesthesia types. Results A total of 1513 patients were included in this study. After exclusions are applied, 263 patients remain in the INHA group and 208 in the TIVA group. Patients receiving INHA have a lower 5-year overall survival rate than that of patients receiving TIVA [12.6% (95% CI, 9.0 to 17.3) vs. 17.7% (95% CI, 11.3 to 20.8), P=0.024]. Results of multivariable Cox-regression analysis also identify that INHA anesthesia is significantly associated with mortality and cancer recurrence after surgery compare to TIVA, with HR (95%CI) of 1.303 (1.065, 1.595) and 1.265 (1.040, 1.539), respectively. Subgroup analysis suggested that in more severe cancer patients, the worse outcome related to INHA might be more significant. Conclusion This retrospective analysis identifies that TIVA has better survival outcomes compare to INHA in HCC patients with PVTT. Future prospective researches are urgent to verify this difference and figure out underlying causes of it.

Abstract BackgroundTo evaluate the impact of postoperative radiotherapy (PORT) on survival in olfactory neuroblastoma (ONB) patients with different stages. MethodsPatients with ONB were selected in the Surveillance, Epidemiology, and End Results (SEER) database during 2004–2016. Survival analyses were performed using Kaplan Meier (K-M) method, Cox regression analysis, and competing risk model. ResultsA total of 513 patients were included in the study. Univariate and multivariate analysis results demonstrated that PORT was not an independent prognostic factor for overall survival (OS) of patients with modified Kadish stage A and B (p=0.699 and p=0.248, respectively). For C and D cases, patients who underwent PORT had significantly better OS than those who did not undergo PORT (p=0.03 and p< 0.0001, respectively). K-M curves illustrated that the 5- and 10-year OS rates according to radiotherapy (PORT vs. non-PORT) were 70.4% vs. 85.3% and 56.8% vs. 68.2% in stage C, respectively. For stage D patients, the 5-year OS rates were 42.6% and 70.7%, and 10-year OS rates were 29.5% and 53.4% in the PORT and non-PORT groups, respectively. The competitive risk model revealed that the 5-year cancer-specific cumulative mortality incidence decreased by 26.6% and the 10-year mortality incidence by 41.4% in patients with stage C who were treated using PORT; meanwhile, for patients with stage D who were treated with PORT, the 5- and 10-year mortality incidence reduced by 35.3% and 42.6%, respectively. Chemotherapy was not related to the prognosis of ONB (all p> 0.05).ConclusionsOur results indicate that PORT improved survival outcomes in ONB patients with modified Kadish stage C and D. However, for modified Kadish stage A and B cases, PORT may not affect survival. Chemotherapy was not recommended for ONB patients until more studies determine the role of chemotherapy.

Abstract Abstract 3973 Introduction: Cereblon (CRBN) expression has been described to be essential for the activity of Thalidomide and Lenalidomide. This suggests that presence and possibly increased level of CRBN expression would be associated with better outcome in Thalidomide/Lenalidomide treated patients. The aim of this study was to evaluate CRBN expression in relation to outcome in patients receiving Thalidomide maintenance. Patients and methods: The HOVON-65/GMMG-HD4 trial is a multi-center, phase III trial, comparing Bortezomib in induction and post-intensification vs. conventional chemotherapy and daily Thalidomide 50 mg for 2 years post-intensification in newly diagnosed MM patients. This trial demonstrated that Bortezomib during induction and maintenance improved CR and achieved superior PFS and OS (Sonneveld et al., JCO, July 16, 2012). Gene expression profiling was performed at the start of the trial by Affymetrix U133 Plus 2.0 GeneChip, and was available for 96 patients which started Thalidomide maintenance. CRBN expression levels were based on a combined value of probe sets 218142_s_at and 222533_at. CRBN expression was validated using real-time PCR. All survival analyses were performed in SPSS, with survival time taken from the start of maintenance. Results: In patients receiving Thalidomide maintenance, increased CRBN expression was significantly associated with longer progression free survival (p=0.005, hazard ratio = 0.7) and longer overall survival (p=0.04, hazard ratio= 0.7). Using Kaplan-Meier analysis for visualization and using the median expression to define high and low expression, a significant separation was found for PFS (Log rank p=0.009) but not for OS (Log rank p=0.13). No association was observed between CRBN expression and PFS/OS after Bortezomib maintenance (PFS, p=0.4, hazard ratio=1.1; OS, p=0.7, hazard ratio=1.1). Multivariate Cox regression analysis was performed using the covariates ISS, CRBN and high-risk cytogenetics, defined as having del(17p) and/or 1q gain and/or t(4;14). Higher CRBN levels remained significantly related to longer PFS (hazard ratio 0.7, p=0.03), but not OS (hazard ratio of 0.8, p=0.3). High-risk cytogenetics and ISS were both significant in both PFS and OS multivariate models, with hazard ratios of 2.8 and 3.6, for high-risk cytogenetics and 2.5 and 5.5, for ISS stage 3, respectively (p=0.0004, p=0.003, high-risk cytogenetics and p=0.01 and p=0.005, ISS stage 3, respectively). Conclusion: These data suggest use of CRBN as a biomarker for thalidomide outcome, but further analysis in other Thalidomide trials is required to validate this finding.

Abstract Abstract 931 Background: Cereblon (CRBN), an adaptor protein of the Cul4A-DDB1-ROC1 ubiquitin E3 ligase complex was recently identified as a primary target of thalidomide teratogenicity and as essential requirement for IMiDs mediated cytotoxicity in multiple myeloma (MM) cells in vitro (Zhu YX et al, 2011). We have undertaken the current study to confirm the association between cereblon protein expression and the clinical response to lenalidomide. Methods: We constructed tissue microarrays (TMA) using bone marrow biopsies collected immediately prior to initiating therapy with lenalidomide. Fluorescence immunohistochemistry was performed using a polyclonal anti-CRBN antibody (HDA045910, Sigma-Aldrich) at a dilution of 1:4000, with 3 minutes of antigen retrieval at 121°C in a decloaking chamber in a pH=9 Tris/EDTA-based buffer (S2367, Dako). Tissue microarray slides were scanned on a HistoRx PM-2000 and digital images where analyzed with AQUA analysis software to determine the CRBN AQUA scores (protein expression = AQUA scores defined as the average CRBN pixel intensity within CD138 positive cells). CRBN AQUA scores where standardized on the Z-distribution (Z= X-μ/σ). The clinical parameters, response criteria and survival outcomes (PFS and OS) of these patients were defined according to the international uniform response criteria. The Kaplan-Meier method was used to estimate OS and PFS. Multivariate analysis was performed using the Cox regression method. Results: 42 patients with newly diagnosed (71.4%) or relapsed / refractory (28.6%) MM patients treated with lenalidomide and dexamethasone (MM009, MM016 or MM020 trials) and available pre-treatment bone marrow biopsies were included in this analysis. In this cohort, median age was 68 (range 46–88), median Hb 114 g/L (range 77–145), median Calcium 2.35 mmol/L (range 1.62–2.82), median creatinine 91.5 μmoles/L (range 44–500), high LDH in 21.4%, median albumin 35.5 g/L (range 23–47), β2 microglobulin 4.66 mg/L (range 1.2–35.19), ISS I 19%, II 35.7% and III 45.3% and high-risk cytogenetics (del17p13, t(4;14) by FISH) in 26.6%. Response CR/nCR was observed in 13/42 (31 %), PR in 21/42 (50%), MR in 4/42 (9.5%) and PD in 4/42 (9.5%). With a median follow-up of 22.4 months (range 0.72–65.6), 28/42 (67%) progressed with mPFS 19.53 months (95% CI 8.57–30.496) and mOS 28.733 months (95% CI 24.061–33.406). Cereblon expression or AQUA normalized Z scores ranged from -1.419 to 3.895. Kaplan Meier log-rank survival analysis were generated based on CRBN normalized AQUA Z scores with the bottom (Q4) and top quartiles (Q1-3) defined as CRBN-low or CRBN-high groups respectively. PFS was significantly shorter in CRBN-low (5.633 months) versus CRBN-high (19.733 months; p= 0.008). Similarly, OS was also reduced in CRBN-low patients (11.4 versus 30.467 months; p=0.033). In univariate Cox regression analysis, cereblon protein expression was significantly associated with PFS (HR 0.322; 95% CI 0.133–0.780; p=0.012) and OS (HR 0.323; 95% CI 0.108–0.970; p=0.044). Cereblon expression remained an independent predictor of PFS (HR 0.161; p=0.01) but not for OS when ISS and cytogenetics were included in multivariate regression analysis. In the CRBN-high group only 5/31 patients (16.1%), compared to 54.5% (6/11) in the CRBN-low group, failed to respond (≤MR) to lenalidomide. Similar to the protein tissue array analysis, low CRBN mRNA was also significantly associated with shorter PFS (p=0.008) in a chip microarray analysis of CRBN expression (Affymetrix probe 222533_at) in a cohort of 32 MM patients treated with lenalidomide and dexamethasone. Cereblon protein expression (AQUA normalized Z score) significantly correlated with CRBN mRNA microarray values (Affymetrix probe 222533_at) in 17 patients with matching protein and mRNA samples (Spearman's rho 0.417; p= 0.048). In contrast, and confirming the specificity of cereblon for response to IMiDs, no association between cereblon protein expression and response to therapy or survival outcomes (PFS/OS) was observed in a independent cohort of newly diagnosed MM patients (n=37) treated with bortezomib induction therapy and ASCT. Conclusion: Using an automated, observer-independent and fully quantitative approach, our studies confirm the association between cereblon protein expression and response to lenalidomide in MM.

THE OBJECTIVEof the study was to assess the impact of the count of interstitial CD3+, CD68+ and CD20+ cells on long-term prognosis of renal allograft (RA).PATIENTS AND METHODS.86 RA recipients with biopsy-proven according to the Banff 2013- 2017 criteria glomerulitis were enrolled in this retrospective study. The patients were subdivided into the following groups: 1) isolated glomerulitis with negative donor-specific antibodies (DSA) at the biopsy (n=53); 2) glomerulitis with positive DSA (n=22); 3) glomerulitis with undetermined DSA (n=11). Quantitative assay of interstitial positive cells was performed after immunohistochemical staining for CD68+, CD3+, CD20+. The Kaplan-Meier method and Cox proportional hazards regression model were used for the analysis of the relationship between interstitial CD3+, CD68+, CD20+ cells and risk of RA loss.RESULTS.CD68+ and CD3+ cells prevailed in interstitium in RA glomerulitis. CD20+ infiltrates were found in 60% of cases. CD20+ cells tended to form infiltrates, in 9 cases these infiltrates reached large sizes (≥ 50 CD20+ lymphocytes) and formed nodular structures. There was no difference in the count of interstitial CD3+ and CD68+ cells and in the presence of CD20+ infiltrates between DSA subgroups. Interstitial CD68+ ≥ 5 cells per field of view (FOV) (x400) and CD3+ ≥ 8 cells per FOV (x400), as well as the presence of large CD20+ infiltrates were associated with a lower RA survival (plog-rank < 0,05). Interstitial CD68+ (≥ 5 cells/FOV), CD3 + (≥ 8 cells/FOV) and the presence of large CD20+ interstitial infiltrates were independently associated with the risk of RA loss in the multivariable Cox regression analysis adjusted for DSA, cold and warm ischemia time (p < 0.05). CONCLUSION. Grade of interstitial infiltration by CD68+, CD3+ and CD20+ cells in RA glomerulitis could be independent predictor of RA loss.

Background WD repeat domain 76 (WDR76) is a predicted member of the WD40-repeat-containing domain superfamily and possibly involves in various biological processes, but its function in cancers is poorly characterized. This study aimed to evaluate the role of WDR76 in the prognosis and immune infiltrates of lung adenocarcinoma (LUAD). Methods WDR76 expressions in LUAD tissues and normal tissues were primarily compared by The Cancer Genome Atlas (TCGA) database, and were validated in cohorts from Gene Expression Omnibus (GEO) database. The associations between WDR76 expression and clinicopathologic characteristics were analyzed. Kaplan–Meier and Cox regression analyses were performed to determine the impact of WDR76 expression on survival outcomes. The protein interaction network of WDR76 was built using STRING website. TIMER and GEPIA databases were used to investigate the correlation between WDR76 expression and immune infiltrates. Results WDR76 expression was elevated in LUAD (P < 0.001) and high WDR76 expression was associated with advanced N stage, M stage and pathologic stage. Expectedly, high WDR76 expression significantly correlated with poor survival outcomes and was the independent risk factor for overall survival (OS) (HR 1.468, 95% CI [1.031–2.089], P = 0.033) and disease specific survival (DSS) (HR 1.764, 95% CI [1.095–2.842], P = 0.020). DDB1 and LSH were the important proteins interacting with WDR76. WDR76 expression correlated with CD8+ T cells presence and was also positively associated with levels of inhibitory receptors. Conclusion WDR76 expression was involved in the regulation of immune infiltrates and had predictive value for prognosis in LUAD.

The Impact

BACKGROUND: CA125 level normalization at different chemotherapy cycles has been reported to be a prognosticator in advanced epithelial ovarian cancer. OBJECTIVE: In the present study, we investigated whether the time (in days) to CA125 normalization or nadir during treatment could be used as markers to predict survival. METHODS: Patients with FIGO stage III–IV epithelial ovarian cancer treated with cytoreductive surgery followed by adjuvant chemotherapy between 2008 and 2016 were enrolled in this retrospective study. Clinicopathological characteristics, changes in CA125 level during treatment, and survival outcomes were analyzed. Time-dependent receiver operating characteristic curve analysis was used to determine the optimal cut-off values of the time to normalization and time to nadir of CA125 levels to predict survival. Univariate and multivariate Cox regression analysis were used to examine the impact of each variable on survival. RESULTS: A total of 106 patients were included in the analysis. The optimal cut-off values for the time to normalization and nadir for predicting survival were 60 and 194 days, respectively. In Kaplan-Meier survival analysis, CA125 level normalization ⩽ 60 days and CA125 ⩽ 35 u/mL after the third cycle, and CA125 level ⩽ 10 u/mL after the sixth cycle of chemotherapy were associated with significantly better 5-year progression-free survival (PFS) and overall survival (OS). In multivariate analysis, only CA125 level normalization > 60 days was significantly associated with poor survival outcomes (PFS, HR 2.62 [95% CI: 1.54, 4.45], p= 0.004; OS, HR 2.40 [95% CI: 1.19, 4.81], p= 0.014). CONCLUSIONS: Normalization of CA125 level within 60 days after cytoreductive surgery followed by adjuvant chemotherapy in patients with advanced ovarian epithelial cancer could be used as a marker to predict survival.
