Inferior OS Research Articles

Body composition as a prognostic factor in cholangiocarcinoma: a meta-analysis

This investigation seeks to scrutinize the relationships between body composition metrics and the clinical outcomes observed in patients with cholangiocarcinoma (CCA). A comprehensive exploration was conducted across three prominent online databases: Embase, PubMed, and the Cochrane Library. This endeavor spanned the entirety of each database up to the cutoff date of September 29, 2023. To evaluate the quality of the included studies, the Newcastle-Ottawa scale was employed. This comprehensive analysis included a total of 26 articles with a combined patient cohort of 4398 individuals. The results demonstrated that CCA patients with low skeletal muscle index (SMI) had significantly inferior OS (HR: 1.93, p < 0.001) and RFS (HR: 2.02, p < 0.001), as well as a higher incidence of postoperative complications (OR: 1.69, 95% CI: 1.20–2.38, p < 0.001) compared to those with high SMI. The presence of sarcopenia in CCA patients was significantly related to poorer OS (HR: 1.96, p < 0.001) and RFS (HR: 2.05, p < 0.001), and a higher rate of postoperative complications (OR: 1.39, p = 0.049) in comparison to those without sarcopenia. Moreover, lower psoas muscle index (PMI) and myosteatosis were associated with shorter OS (PMI, HR: 1.56, p < 0.001; myosteatosis, HR: 1.49, p = 0.001) and RFS (PMI, HR: 2.16, p < 0.001; myosteatosis, HR: 1.35, p = 0.023). Our findings highlight incorporating body composition screening into clinical practice can help develop treatment strategies and optimize perioperative care, potentially improving patient outcomes.

Prognostic Value of Triglyceride-Glucose Index in Acute Myeloid Leukemia: A Retrospective Study

Background: Acute myeloid leukemia (AML) is an incurable hematological malignancy. The triglyceride-glucose (TYG) index is a surrogate marker for insulin resistance, but its relationship with AML prognosis remains unclear. This study aimed to investigate the prognostic value of the TYG index in AML. Methods: We retrospectively analyzed laboratory test data of 158 initially diagnosed AML patients and calculated the TYG index. The association between TYG index and patient prognosis was evaluated by survival curve. We constructed a prognostic nomogram through multivariate Cox regression analyses, and its performance was evaluated using calibration curves, the C-index, and the area under the curve (AUC). Results: A total of 158 AML patients, aged between 18 and 83 years (mean age 50.48 years), were included in this study from January 2017 to June 2023. Of these, 131 patients (82.9%) achieved CR after one or two courses of induction chemotherapy. 81 patients (51.27%) were male, 71 patients (44.94%) relapsed and 89 patients (56.32%) died at the end of follow-up. The median follow-up time was 27 months. According to the 2017 European Leukemia Network (ELN2017) genetic risk stratification, 44 (27.85%), 59 (37.34%), and 55 (34.81%) of patients were classified into favorable, intermediate, and adverse risk groups, respectively. Fasting glucose and fasting triglycerides were measured at diagnosis, with a median TYG index level of 1.28. Patients were divided into high and low TYG index groups based on median value. We investigated the impact of TYG index on RFS and OS. Patients with high TYG index had significantly inferior RFS and OS compared to those with low TYG index (5-year RFS: 52.9% vs. 16.2%, log-rank P&amp;lt;0.001; 5-year OS: 42.6% vs. 20.8%, log-rank P&amp;lt;0.01). We further investigated whether the TYG index could stratify patients within each ELN risk group. In the intermediate risk group, patients with high TYG index also had significantly inferior RFS and OS compared to those with low TYG index patients (5-year RFS: 53.6% vs. 14.4%, log-rank P&amp;lt;0.01; 5-year OS: 43.9% vs. 23.2%, log-rank P&amp;lt;0.05). Similar results were observed in the adverse risk groups for RFS (2-year RFS: 51.5% vs. 9.3%, log-rank P&amp;lt;0.05) but not for OS. Although there was no statistically significant difference in the favorable risk group, there was a trend toward worse RFS and OS for patients with high TYG index. In particular, among the 22 patients with AML-ETO positivity in the favorable risk group, those with high TYG index had significantly inferior RFS and OS compared to those with low TYG index (3-year RFS: 91.7% vs. 14.6%, log-rank P&amp;lt;0.01; 5-year OS: 85.1% vs. 28.6%, log-rank P&amp;lt;0.05). Multivariate analysis showed that TYG index was an independent prognostic factor for both OS (HR 1.502, 95%CI 1.139-1.981) and RFS (HR 1.526, 95%CI 1.110-2.099) in AML patients. A new prognostic nomogram was developed, incorporating the TYG index, age, and ELN2017. This nomogram demonstrated high predictive accuracy for 1-year, 3-year, and 5-year OS in AML patients, with AUCs of 0.789, 0.764, and 0.798, respectively. Conclusions: The TYG index is an independent prognostic factor for AML. The new nomogram, which combines TYG index, age, and ELN2017 genetic risk stratification, provides a quick and simple method with high clinical value for predicting the prognosis of AML patients.

Meta-Analysis of Age, Sex, and Race Disparities in the Era of Contemporary Urothelial Carcinoma Treatment

Background: Urothelial carcinoma (UC) is one of the most common cancers diagnosed worldwide. However, minority populations, such as female, elder, and Black patients, may have disparate outcomes and are commonly neglected in randomized prospective trials. This review aims to study the relationship between age, sex, and race on urothelial cancer prognosis, particularly focusing on contemporary therapy and its effect on overall survival. Methods: Phase III prospective trials since 2016 of immune checkpoint inhibitors, antibody-drug conjugates, or targeted therapies in urothelial carcinoma were identified from PubMed. Trials that did not report on survival by race, sex, or age distribution were excluded, and remaining trials (n = 17) were compared by subgroup. Results: Women were reported to have inferior OS on investigational agents compared to men in 9/17 trials. In a meta-analysis, women had inferior OS to men (OR 0.89 [95% CI: 0.78–0.99]; p = 0.04). Asian/Pacific Islander patients had inferior outcomes to White patients on investigational agents in 3/5 trials. In a meta-analysis, OS was not significant by race (OR 1.18 [0.90–1.46], p = 0.38). Black patients composed &lt;2% of all trial patients, and no subgroup data were reported. Both 65 (n = 7) and 75 (n = 2) were reported as age cut-offs in trial subgroups, and survival data were mixed. Conclusions: Women in UC trials may have inferior survival outcomes to men. Racial diversity was poor and thus limited any conclusions on survival disparities.

Response to induction chemotherapy modifies the effect of conventional prognostic factors in high-risk neuroblastoma: A report from the Children’s Oncology Group

BackgroundResponse to induction chemotherapy has been shown to predict outcome in patients with high-risk neuroblastoma (HR-NB), with those achieving a complete response (CR) having superior outcomes. MethodsWe evaluated whether conventional prognostic factors remain prognostic in subsets of patients defined by response to induction. 1244 Patients from four COG high-risk trials were included. End-induction response was coded as CR, partial response (PR) or better, less than PR without progressive disease (PD), and PD. Cox regression models were performed to calculate event-free and overall survival (EFS, OS) hazard ratios, including interaction terms between induction response and prognostic factors including sex, age, stage, primary tumor location, LDH, ferritin, ploidy, MYCN status, ALK status, histology, MKI, grade, and study era. ResultsAmong patients who achieved a CR after induction, INSS stage 4 disease and trial era were the only factors that remained significantly associated with inferior OS. For those who achieved less than a PR, adrenal primary site, MYCN amplification, and 1p LOH were associated with inferior outcomes. Multivariable models showed that end-induction response remained prognostic of EFS and OS even after controlling for other factors. Multiple significant statistical interactions were observed between end-induction response and other prognostic factors. ConclusionThe impact of conventional prognostic factors is not static in patients with HR-NB. Instead, response to induction chemotherapy modifies the effect of conventional prognostic factors. These data can help to further refine prognosis for patients with variable responses to induction and help to identify candidates who might benefit from treatment other than standard post-induction therapy.

Metabolic tumor volume from baseline [18F]FDG PET/CT at diagnosis improves the IPI stratification in patients with diffuse large B-cell lymphoma.

Although several different parameters of PET/CT were reported to be predictive of survival in DLBCL, the best parameter remains to be elucidated and whether it could improve the risk stratification of IPI in patients with DLBCL. 262 DLBCL patients including in the training and validation cohort were retrospectively analyzed in this study. Among different parameters, MTV was identified as the optimal prognostic parameter with a maximum area under the curve (AUC) of 0.652 ± 0.112 than TLG and SDmax (0.645 ± 0.113 and 0.600 ± 0.117, respectively). Patients with high MTV were associated with inferior PFS (p < 0.001 and p = 0.021, respectively) and OS (p < 0.001 and p < 0.001, respectively) in both the training and validation cohort. The multivariate analysis revealed that high MTV was an unfavorable factor for PFS (relative ratio [RR], 2.295; 95% confidence interval [CI], 1.457-3.615; p < 0.01) and OS (RR, 2.929; 95% CI 1.679-5.109; p < 0.01) independent of IPI. Further analysis showed MTV could improve the risk stratification of IPI for both PFS and OS (p < 0.01 and p < 0.01, respectively). In conclusion, our study suggests that MTV was an optimal prognostic parameter of PET/CT for survival and it could improve the risk stratification of IPI in DLBCL, which may help to guide treatment in clinical trial.

Prognostic impact of body composition in hepatocellular carcinoma patients with immunotherapy

Objective This study aims to examine the possible relationship between body composition parameters, sarcopenia, and clinical outcomes in hepatocellular carcinoma (HCC) patients who received immune checkpoint inhibitor (ICI) treatment. Methods Three online databases, including Embase, PubMed, and the Cochrane Library, were thoroughly searched for literature describing the relationship between body composition parameters, sarcopenia, and outcomes of ICI-treated HCC patients from the start of each database to 21 January 2024. The Newcastle-Ottawa Scale was used to rate the quality of the studies. The assessed outcomes included hazard ratio (HR) for OS and PFS, as well as odds ratio (OR) for ORR and DCR. Results This analysis included a total of 15 articles with a combined patient cohort of 1543 individuals. The results demonstrated that HCC patients with low skeletal muscle index (SMI) had significantly inferior OS (HR: 1.68, p < 0.001), PFS (HR: 1.45, p < 0.001), ORR (OR: 0.64, p = 0.044), and DCR (OR: 0.58, p = 0.009) compared to those with high SMI. The presence of sarcopenia in HCC patients was significantly related to poorer OS (HR: 1.63, p < 0.001) and PFS (HR: 1.48, p < 0.001), as well as a lower ORR (OR: 0.64, p = 0.020) and DCR (OR: 0.58, p = 0.007) in comparison to those without sarcopenia. Subgroup analysis demonstrated that these findings were consistent with the multivariate analysis. Moreover, high subcutaneous adipose index (SAI) levels were associated with better OS (HR: 0.46, p = 0.001) and PFS (HR: 0.68, p = 0.021) than those with low SAI levels. Conclusion The presence of sarcopenia and low SMI in HCC patients undergoing treatment with ICIs was found to be related to inferior treatment response and reduced long-term effectiveness.

Fludarabine, busulfan, and melphalan conditioning regimen in allogeneic hematopoietic stem cell transplantation for adult patients with myeloid malignancies: A multicenter retrospective study.

Relapse remains the main cause of treatment failure in patients with myeloid malignancies even after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We observed a particularly low incidence of relapse in patients prepared with fludarabine, busulfan and melphalan in our previous study and this multicenter retrospective analysis aimed to confirm the feasibility of the regimen and to identify the potential prognostic factors. This study was performed using registry data from adults patients with myeloid malignancies who underwent their first allo-HSCT following fludarabine(≥100mg/m2), busulfan (≥3.2mg/kg) and melphalan (≥100mg/m2) based conditioning at nine transplantation centers in China between Jan. 2020 and Mar. 2022. A total of 221 consecutive patients (AML n=171, MDS-IB-1 or 2 n=44, CMML n=6) with median age of 46 were enrolled in this study. The median follow-up was 507 days for survivors. The 2-year NRM, CIR, OS and DFS were 10.6%±2.2%, 14.8%±3.3%, 79.4%±3.7% and 74.6%±3.7%, respectively. In multivariate analyses, high HCT-CI (≥3) was the only independent factor for higher NRM [hazard ratio (HR), 2.96; 95% confidence interval (CI), 1.11 to 7.90; p=0.030] and ECOG score ≥2 was the only independent factor for inferior OS (HR, 2.43; 95%CI, 1.15 to 5.16; p=0.020) and DFS (HR, 2.12; 95%CI, 1.13 to 4.02; p=0.020). AML diagnosis and positive measurable residual disease (MRD) at transplantation were predictors for higher CIR (HR=7.92, 95%CI 1.05-60.03, p=0.045; HR=3.64, 95%CI 1.40-9.44, p=0.008; respectively), while post-transplantation cyclophosphamide based graft-versus-host disease prophylaxis was associated with lower CIR (HR=0.24 95%CI 0.11-0.54, p=0.001). The intensity of conditioning regimen did not impact CIR, NRM, DFS and OS. These results supported that double alkylating agents of busulfan and melphalan based conditioning regimens were associated with low relapse rate and acceptable NRM in adult patients with myeloid malignancies. The optimal dose remained to be confirmed by further prospective studies.

Adjuvant therapy may improve overall survival in high-risk periampullary adenocarcinomas patients – A match-pair analysis from a multi-institutional cohort study (The MIPPAP study)

BackgroundThe role of adjuvant therapy in resected periampullary adenocarcinomas is equivocal due to contrasting data and limited prospective trials. MethodsThe Multicentre Indian Pancreatic & Periampullary Adenocarcinoma Project (MIPPAP), included data from 8 institutions across India. Of the 1679 pancreatic resections, 736 patients with T3/T4 and/or Node positive adenocarcinomas (considered as high risk for recurrence) were included for analysis. Three (adjuvant): one (observation) matching, using T3/T4 T staging, nodal positivity and ampullary subtype was performed by using the nearest neighbour matching method. ResultsOf 736 patients eligible for inclusion, 621 patients were matched of which 458 patients received adjuvant therapy (AT) (predominantly gemcitabine-based) and 163 patients were observed (O). With a median follow-up of 42 months, there was a statistical difference in overall survival in favour of patients receiving AT as compared to those on observation [68.7 months vs. 61.1 months, Hazard ratio: 0.73 (95% CI: 0.54–0.97); p = 0.03]. Besides AT, presence of nodal involvement (median OS: 65.4 months vs not reached; p = 0.04) predicted for inferior OS. ConclusionsThe results of the match-pair analysis suggest that adjuvant therapy improves overall survival in periampullary adenocarcinomas at high risk of recurrence with a greater benefit in T3/T4, node-positive and ampullary subtypes.

Influence of body fat tissue on outcomes in patients undergoing hepatectomy or liver transplantation.

The purpose of this study is to investigate potential associations between body fat composition and postoperative outcomes in patients with hepatectomy or liver transplantation. Three online databases, including Embase, PubMed, and the Cochrane Library, were thoroughly searched for literature describing the relationship between body fat composition and outcomes of patients with liver surgery from the start of each database to October 29, 2023. The Newcastle-Ottawa Scale was used to rate the quality of the studies. This analysis included a total of 29 articles with a combined patient cohort of 6,435 individuals. The results demonstrated that patients with high intramuscular fat content (IMFC) had significantly inferior OS (HR: 2.07, 95% CI: 1.69-2.53, P < 0.001) and RFS (HR: 1.61, 95% CI: 1.20-2.16, P = 0.002) and a higher risk of major complications (HR: 2.20, 95% CI: 1.59-3.05, P < 0.001). We also found that the presence of high visceral-to-subcutaneous fat tissue ratio (VSR) in patients with liver surgery was significantly related to poorer OS (HR: 1.70, 95% CI: 1.44-2.00, P < 0.001) and PFS (HR: 1.29, 95% CI: 1.11-1.50, P = 0.001) and a higher major complication rate (HR: 2.31, 95% CI: 1.17-4.56, P = 0.016). Besides, the synthesized findings indicated there is no significant correlation between visceral fat tissue and survival outcomes or postoperative complications. In summary, preoperative IMFC and VSR have the potential to forecast poorer OS and RFS and a higher risk of complications for patients undergoing hepatectomy or liver transplantation.

Impact of late immune effector cell associated hematotoxicity (ICAHT) and prolonged neutropenia after CAR-T therapy on infection and survival outcomes.

7041 Background: Prolonged hematologic toxicity is a common side effect of chimeric antigen receptor T-cell (CART) therapy. The EHA/EBMT panel developed the late ICAHT grading which incorporates depth of neutropenia after Day 30. Recently, the early ICAHT grade (D 0-30) was associated with infection (infx) and survival outcomes. Here, we evaluate the impact of late ICAHT and neutropenia on survival and infx outcomes after CD19 CART. Methods: We included two cohorts of adult patients (pts) with large B cell lymphoma (LBCL), mantle cell lymphoma (MCL), and follicular lymphoma (FL) who received commercial CD19 CART. Late was graded based on depth of neutropenia after D30 (G1 ≤ 1.5; G2 ≤ 1.0; G3 ≤ 0.5; G4 ≤ 0.1 G/L) and pts were censored for relapse, progression, or loss of follow up. Infxs after D30 were graded per CTCAE as mild G ≤ 2 or severe G ≥ 3. Cohort 1 included pts from 8 US medical centers for survival outcomes. Only data for severe infx was collected from D30-D100 and longer term infx data was not available. Landmark survival analysis at D+100 was performed using the Kaplan-Meier method and multivariate cox proportional hazards. To assess long term late infx outcomes, cohort 2 included pts at Vanderbilt with granular cytopenia and infx data (D30-365). Results: Cohort 1 included 277 pts with LBCL of whom 143 received axi-cel, 61 tisa-cel, and 72 liso-cel with median follow up 395 days (range 30-1763). By D100, there were 111 (40%) without, 89 (41%) with mild to moderate (G1-G2), and 53 (19%) with severe (G3-G4) late ICAHT. There were 13 pts (6%) with severe infx which was not associated with severe ICAHT (p=0.68). In multivariate landmark survival analysis using previously published covariates, severe late ICAHT was not associated with PFS (HR 1.64, p=0.11) or OS (HR 1.54, p=0.17); however, D100 neutropenia (ANC ≤ 1000) was associated with inferior PFS (HR 2.00, p=0.002) and OS (HR 1.95, p=0.003). NRM was 11% and associated with D100 neutropenia (p=0.015) but not late ICAHT (p=0.15). Cohort 2 had 43 pts (35 LBCL, 7 MCL, 1 FL) with median follow up 483 days (range 233-2133). 34 pts received axi-cel, 2 tisa-cel, and 7 brexu-cel. By 1 yr, there were 10 (23%) without, 27 (63%) with mild to moderate, and 6 (14%) with severe late ICAHT. There were 52 infxs by 1 yr and 16 pts (37%) had no infx. Median time to first infx after D30 was 165 days (range 31-365). There were 31 (60%) mild and 21 (40%) severe infx. IVIG was used in 28 (65%) and G-CSF in 27 (62%). Only 1 pt with severe ICAHT had severe infx. Late ICAHT and neutropenia were not associated with severe infection in logistic regression. Conclusions: These data did not show an association between EHA/EBMT late ICAHT grading and infx after D30 or survival. A detailed reporting of T and B cell reconstitution data may provide clues to better predict late infx. Persistent neutropenia at D100 was associated with inferior PFS and OS which needs validation in future studies.

Bi-institutional spline curve analysis of lymph node mapping in gallbladder cancer operated over 12 years: Impact of location and number of lymph nodal stations.

e16274 Background: Current staging system for gallbladder cancers (GBC) takes into account only the number of metastatic lymph nodes without addressing their location. The current study evaluates the prognostic impact of lymph node mapping (number and location) in node positive GBCs. Methods: Prospectively maintained operative database of GBC patients with positive lymph nodes were analysed from two tertiary cancer care centers in a retrospective cohort study design between April 2010 till March 2022. Nodal burden was assessed including both, the number of metastatic nodes and the lymph node station. Impact of lymph node ratio (LNR) and log odds of positive lymph nodes (LODDS) was evaluated using regression and spline curve analysis. Results: Amongst 1312 operated GBC patients, 272 patients with node positive disease were included. The median nodal yield was 8. The median LNR and LODDS was 0.222 and -0.48 respectively. The 5-year DFS and OS for patients with only cystic node metastases was 52.3% and 50.8% respectively (median: not reached), as compared to 24.6% and 35.2% for involvement of regional nodal stations beyond cystic nodes. Higher LODDS was associated with inferior DFS and OS when compared to the LNR. On multivariate analysis, multi-station involvement was the only factor associated with inferior DFS (p &lt; 0.001) and OS (p = 0.007). Conclusions: Station wise pathological assessment of lymph nodal involvement could potentially provide superior prognostic information, in addition to number of involved nodes. Involvement of cystic lymph node alone has relatively superior prognosis as compared to multi-station involvement.

Impact of JAK2 allele burden on MF outcome in the era of ruxolitinib.

6514 Background: Myelodepleted myelofibrosis (MF), characterized bycytopenias, lower JAK2V617F allele burden (JAK2%) and shorter benefit from JAKi ruxolitinib (RUX), has worse survival (OS) compared to myeloproliferative MF. Lower JAK2% and inferior OS is more typical for primary MF (PMF) vs MF from essential thrombocythemia or polycythemia vera (PPV/PET-MF). We sought to investigate the impact of JAK2% (&lt;/≥ 50%), cytopenias and the use of RUX in outcome of PMF/PPV-PET-MF patients from our center. Methods: 601 medical charts of JAK2 mutated patients with MF (known JAK2%) were retrospectively reviewed. We divided patients based on the absence (-) or presence (+) of cytopenias (hemoglobin &lt; 10 g/dL or platelets &lt; 100 x10^9/L) and leukocytosis (WBC ≥ 25 x10^9/L) into: Gr1 = (-)/(-) [absence of both]; Gr2 = (-)/(+) [proliferative]; Gr3 = (+)/(-) [cytopenic]; Gr4 = (+)/(+) [cytopenic and proliferative]) and evaluated OS per JAK2 &lt;/≥ 50% and PMF vs PPV/PET-MF. We assessed the tolerance of RUX ≥3 years. We used descriptive statistics, Kaplan-Meier curve with log-rank test and regression analysis for demographics, estimation of OS and its comparison. OS was censored at the time of stem cell transplantation. Results: Median age of the entire cohort was 75 years (64% males). Patients with JAK2 &lt;50%, more likely PMF, had more anemia and thrombocytopenia, higher blasts, less leukocytosis, and smaller splenomegaly. JAK2 &lt;/≥ 50% did not discriminate OS of the entire group, PMF or PPV/PET-MF (median OS of ~ 45 months for each; only PPV/PET-MF with 64 months). OS of Gr1-4 according to JAK2 &lt;/≥ 50% and PMF/ PPV/PET-MF and combined OS of patients with comparable outcome (A-D) are shown in the table. The final groups with distinct outcomes included: A+B) non-cytopenic PET/PPV-MF and PMF irrespectively of proliferation and JAK2% - with one exception of non-cytopenic, proliferative PMF with JAK2 ≥50% - had median OS of 70 months (range, 54-86); D) cytopenic and proliferative PMF with any JAK2% and PPV/PET-MF with JAK2 &lt; 50% of median OS 19 months (range, 13-25), and C) the rest of the cytopenic patients and non-cytopenic, proliferative PMF with JAK2 ≥50% with a median OS of 36 months (range, 32-42). Among the 3 final groups, similar proportion of patients were exposed to RUX during their follow-up: 36% (A+B), 31% (B) and 28% (C), respectively (p =0.13). The most patients in (A+B) group were able to tolerate RUX for ≥3 years (p =0.036). All patients had improved OS with RUX (data to be presented). Conclusions: Cytopenias and/or proliferation, rather than JAK2 &lt;/≥50%, define the outcome of PMF and PPV/PET-MF patients. [Table: see text]

Association of Fried’s frailty phenotype, but not the clinical frailty scale, with overall survival in older adults with acute myeloid leukemia.

e23222 Background: Frailty is a geriatric syndrome marked by increased vulnerability to stressors. “Fitness,” is utilized to guide treatment in acute myeloid leukemia (AML) where the intensity of initial induction may be high (anthracycline and cytarabine-based), intermediate (venetoclax combinations), or low (single hypomethylating agent or targeting therapy). Fried’s Frailty Phenotype (FP) combines subjective (self-reported exhaustion, weight loss &gt; 5%, activity level) and objective (4-meter walk speed and grip strength) measures to categorize patients into fit, pre-frail, and frail. In prior work, we demonstrated an association of FP with survival for newly diagnosed older adults with AML. Clinical Frailty Scale (CFS) is a purely subjective score that utilizes chart data to stratify the degree of fitness. The incorporation of objective measures into clinical practice is limited due to time constraints, we sought to determine if CFS could similarly identify frailty and risk-stratify older adults with AML. Methods: Eighty-three patients 60 years or older with a new diagnosis of AML were enrolled on an IRB approved study from September, 2018 to May, 2023 at the Hospital of the University of Pennsylvania. FP was performed prior to initiation of therapy. A CFS certified trainee blinded to FP scores retrospectively reviewed electronic medical records to assign a CFS score. CFS was collapsed into variations defined as CFS fit (1-3), pre-frail (4), and frail (5 or greater); CFS Collapse 1 fit (1-2), pre-frail (3-4), and frail (5 or greater), and CFS Collapse 2 fit (1-4) and mild to moderately frail (5-6). Variations were based on the scale’s descriptions and literature. Results: Median patient age was 71 (range 60-91) years. By European LeukemiaNet 2017, 64% of patients had adverse-risk AML. 39% of patients received IC, 52% received HMA/ven, 6% received HMA alone or targeted therapy, and 2% received supportive care. By FP, 18% were fit, 38% were pre-frail, and 45% were frail. FP was significantly associated with OS (p = 0.047): 2-year OS was 57%, 42%, and 21% in fit, pre-frail, and frail. By CFS, 43% were fit, 32% pre-frail, and 24% frail. CSF was not significantly associated with OS (p = 0.495); 2-year OS was 24%, 35%, and 19% for fit, pre-frail, and frail patients, respectively. CSF collapse 1 (p = 0.249) and 2 (p = 0.070) were not significant. Conclusions: FP identified more patients as frail and was associated with a doubling of early mortality and inferior 2-year OS. CFS identified more patients as fit and was not associated with 2-yr OS. The discrepancy emphasizes the importance of objective measurements to capture frailty and the difficulty in determining frailty based on chart reviews in an acutely ill population. Future work to streamline objective measurements in frailty assessments to increase utilization in clinics given its likely importance for accurate risk-stratification.

Prognostic Factors of Pediatric Acute Myeloid Leukemia Patients with t(8;21) (q22;q22): A Single-Center Retrospective Study.

This retrospective study aimed to analyze the treatment effect and prognostic factors of pediatric acute myeloid leukemia (AML) patients with t(8;21). A total of 268 newly diagnosed pediatric AML (pAML) enrolled from 1 January 2005 to 31 December 2022 were retrospectively reviewed, and 50 (18.7%) patients harbored t(8;21) translocation. CR rate, OS, EFS, and RFS were assessed by multivariate Logistic and Cox regression models in these patients. Of the 50 patients, 2 patients abandoned treatment during the first induction course. Of the remaining 48 patients who received double-induction therapy and were included in the final analyses, CR1 and CR2 were 75.0% (36/48) and 95.8% (46/48), respectively. The overall three-year OS, EFS, and RFS were 68.4% (95% CI, 55.0-85.1), 64.2% (95% CI, 50.7-81.4), and 65.5% (95% CI, 51.9-82.8), respectively. The presence of loss of sex chromosome (LOS) at diagnosis (n = 21) was associated with a better 3-year OS [87.5% (95% CI, 72.7-100) vs. 52.7% (95% CI, 35.1-79.3), p = 0.0089], 3-year EFS [81.6% (95% CI, 64.7-100) vs. 49.7% (95% CI, 32.4-76.4), p = 0.023], and 3-year RFS [81.6% (95% CI, 64.7-100) vs. 51.7% (95% CI, 33.9-78.9), p = 0.036] than those without LOS (n = 27), and it was also an independent good prognostic factor of OS (HR, 0.08 [95% CI, 0.01-0.48], p = 0.005), EFS (HR, 0.22 [95% CI, 0.05-0.85], p = 0.029), and RFS (HR, 0.21 [95% CI, 0.05-0.90], p = 0.035). However, extramedullary leukemia (EML) featured the independent risk factors of inferior OS (HR, 10.99 [95% CI, 2.08-58.12], p = 0.005), EFS (HR, 4.75 [95% CI, 1.10-20.61], p = 0.037), and RFS (HR, 6.55 [95% CI, 1.40-30.63], p = 0.017) in pediatric individuals with t(8;21) AML. Further analysis of combining LOS with EML indicated that the EML+LOS- subgroup had significantly inferior OS (92.9%, [95% CI, 80.3-100]), EFS (86.2%, [95% CI, 70.0-100]), and RFS (86.2%, [95% CI, 80.3-100]) compared to the other three subgroups (all p < 0.001). LOS and EML are independent prognostic factors of OS, EFS, and RFS with t(8;21) pAML patients. LOS combined with EML may help improve risk stratification.

Continuously improving outcome over time after second allogeneic stem cell transplantation in relapsed acute myeloid leukemia: an EBMT registry analysis of 1540 patients

Second allogeneic stem cell transplantation (alloSCT2) is among the most effective treatments for acute myeloid leukemia (AML) relapse after first alloSCT (alloSCT1). Long-term EBMT registry data were used to provide large scale, up-to-date outcome results and to identify factors for improved outcome. Among 1540 recipients of alloSCT2, increasing age, better disease control and performance status before alloSCT2, more use of alternative donors and higher conditioning intensity represented important trends over time. Between the first (2000–2004) and last (2015–2019) period, two-year overall and leukemia-free survival (OS/LFS) increased considerably (OS: 22.5–35%, LFS: 14.5–24.5%). Cumulative relapse incidence (RI) decreased from 64% to 50.7%, whereas graft-versus-host disease and non-relapse mortality (NRM) remained unchanged. In multivariable analysis, later period of alloSCT2 was associated with improved OS/LFS (HR = 0.47/0.53) and reduced RI (HR = 0.44). Beyond, remission duration, disease stage and patient performance score were factors for OS, LFS, RI, and NRM. Myeloablative conditioning for alloSCT2 decreased RI without increasing NRM, leading to improved OS/LFS. Haploidentical or unrelated donors and older age were associated with higher NRM and inferior OS. In summary, outcome after alloSCT2 has continuously improved over the last two decades despite increasing patient age. The identified factors provide clues for the optimized implementation of alloSCT2.

Role of plasma EBV-DNA load and EBER status on newly diagnosed peripheral T-cell lymphoma.

To explore the prognostic and therapeutic role of Epstein-Barr Virus (EBV) on peripheral T-cell lymphoma (PTCL). Totally 262 newly diagnosed PTCL patients who were hospitalized from January 2014 to December 2022 were retrospectively enrolled. Molecular analysis included 31 eligible patients. EBV-encoded RNA (EBER) presence in tumor tissue and EBV DNA levels in patients at baseline (DNA1) and after 4 cycles of chemotherapy (DNA4) were assessed. Our findings revealed that the EBER-positive cohort exhibited significant differences compared to counterparts in overall survival (OS, P = 0.047) and progression-free survival (PFS, P = 0.009). Both DNA1 and DNA4 were significantly associated with inferior OS. Multivariate analysis demonstrated that DNA4 independently affected PTCL prognosis for OS (hazard ratio = 5.1617; 95% confidence interval 1.1017-24.1831; P = 0.037). Treatment with the cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) plus azacytidine regimen showed a better OS compared to CHOP or CHOP plus etoposide for patients with partially positive EBER and EBER positive statuses (P = 0.192), although the improvement was not statistically significant. This study delineated the genetic paradigm of PTCL, comparing genetic differences by EBV status and found that EBER partially positive plus positive patients were more likely to have DNMT3A (P = 0.002), RHOAG17V (P = 0.023), and TET2 mutations (P = 0.032). EBER, DNA1, and DNA4 emerged as sensitive markers for prognosis. CHOP plus azacytidine might present a preferable option for PTCL patients with DNA methylation due to EBV infection.

The impact of cytotoxic therapy on the risk of progression and death in clonal cytopenia(s) of undetermined significance

AbstractClonal cytopenia of undetermined significance (CCUS) is defined by a myeloid driver mutation in the context of otherwise unexplained cytopenia. CCUS has an inherent risk of progressing to myeloid neoplasm. However, it is unknown how exposure to previous cytotoxic therapy may impact the risk of progression and survival. We stratified patients with CCUS by prior exposure to DNA-damaging therapy. Of 151 patients, 46 (30%) had received cytotoxic therapy and were classified as therapy-related CCUS (t-CCUS), whereas 105 (70%) had de novo CCUS. A lower proportion of t-CCUS had hypercellular marrows (17.8% vs 44.8%, P = .002) but had higher median bone marrow blast percentages. After a median follow-up of 2.2 years, t-CCUS had significantly shorter progression-free survival (PFS, 1.8 vs 6.3 years; hazard ratio [HR], 2.1; P = .007) and median overall survival (OS; 3.6 years vs not reached; HR, 2.3; P = .007) compared with CCUS. Univariable and multivariable time-to-event analyses showed that exposure to cytotoxic therapy independently accounted for inferior PFS and OS. Despite the similarities in clinical presentation between CCUS and t-CCUS, we show that exposure to prior cytotoxic therapies was an independent risk factor for inferior outcomes. This suggests that t-CCUS represents a unique clinical entity that needs more stringent monitoring or earlier intervention strategies.

Impact of revised International Staging System 2 risk stratification on outcomes of patients with multiple myeloma receiving autologous haematopoietic stem cell transplantation.

The second revision of the International Staging System (R2-ISS) is a simple tool to risk-stratify newly diagnosed multiple myeloma (NDMM) patients. Here, we completed a retrospective analysis to evaluate the utility of R2-ISS in NDMM patients who underwent up-front autologous haematopoietic stem cell transplantation (auto-HCT). A total of 1291 patients were included, with a median age of 62 years (range 29-83). The distribution of R2-ISS stages was: 123 (10%) stage I, 471 (36%) stage II, 566 (44%) stage III and 131 (10%) stage IV. With a median follow-up of 42.2 months (range 0.3-181.0), the median PFS was 73.0, 65.2, 44.0 and 24.8 months, (p < 0.001) and the median OS was 130.8, 128.5, 94.2 and 61.4 months (p < 0.001) for patients with R2-ISS stages I, II, III and IV respectively. On multivariable analysis (MVA) for PFS, using R2-ISS stage I as reference, R2-ISS stages III (hazard ratio [95% confidence interval], 1.55 [1.05-2.29]; p = 0.028) and IV (2.04 [1.24-3.36]; p = 0.005) were associated with significantly inferior PFS. In the MVA of OS, using R2-ISS stage I as reference, only R2-ISS stage IV was associated with significantly inferior OS (2.43 [1.18-5.01]; p = 0.017). Overall, we found that R2-ISS is a reliable prognostic tool for NDMM patients undergoing up-front auto-HCT.

In the era of Bortezomib-based Induction, intensification of Melphalan-based conditioning with Bortezomib does not improve Survival Outcomes in newly diagnosed Multiple Myeloma: a study from the Chronic Malignancies Working Party of the EBMT

Bortezomib (Vel)- Melphalan 200 mg/m2 (Mel200) (Vel-Mel) has been utilised to intensify conditioning in autologous hematopoietic stem cell transplantation (AHCT) for multiple myeloma (MM). This EBMT registry-based study compared Vel-Mel with Mel200 during upfront AHCT. Between 2010 and 2017, MM patients who received Vel-Mel (n = 292) conditioning were compared with 4,096 Mel200 patients in the same 58 centres. Pre-AHCT, compared to Mel200 patients, Vel-Mel patients had similar International Staging System (ISS) scores and cytogenetic risk profiles; a similar proportion had received bortezomib-based induction (85% and 87.3%, respectively) though they were younger with a better performance status. Vel-Mel patients were more likely to achieve CR post-induction (40.6% vs 20.3%, p < 0.001) and by day 100 of AHCT (CR/VGPR: 70.2 % vs. 57.2%, p < 0.001). There was no difference in 3-year PFS (49% vs 46%, p = 0.06) or early post-AHCT mortality. In multivariable analysis, Vel-Mel associated with inferior PFS (HR: 1.69 (1.27–2.25, p < 0.001) and OS (HR:1.46 (1.14–1.86,p = 0.002), similar to negative effects on PFS of advanced ISS (HR:1.56 (1.33–1.83, p < 0.001), high-risk cytogenetics (HR:1.43(1.18–1.74, p < 0.001) and poor post-induction response(<=PR)(HR: 1.43(1.25–1.62, p < 0.001) Overall, despite superior pre- and post-AHCT responses, there was no improvement in PFS or OS following Vel-Mel. This data supports the findings of the smaller prospective IFM study.

Integrated analysis and validation reveal CYTH4 as a potential prognostic biomarker in acute myeloid leukemia.

Acute myeloid leukemia (AML) is a clonal hematological malignancy with high mortality rates. The identification of novel markers is urgent for AML. Cytohesins are a subfamily of guanine nucleotide exchange factors activating the ADP-ribosylation factor family GTPases. While the important roles of cytohesins have been reported in various cancers, their function in AML remains unclear. The present study aimed to explore the prognostic impact of cytohesin-4 (CYTH4) and the underlying molecular functions. RNA sequencing and AML clinical data were obtained from The Cancer Genome Atlas and Gene Expression Omnibus databases to investigate gene expression and survival. Using the R software, differentially expressed genes were identified between the high- and the low-CYTH4 group. Functional enrichment analysis was conducted by Gene Ontology, Kyoto Encyclopedia of Genes and Genomes, and Gene Set Enrichment Analyses. The CIBERSORTx tool was used to explore the proportions of different immune cell types. The molecular function of CYTH4 was also validated in vitro by examining cell growth, cell cycle, apoptosis and colony-forming ability. CYTH4 was significantly upregulated in AML compared with other cancers and normal tissues. High CYTH4 expression was associated with high white blood count (P=0.004) and higher risk status (P<0.001). Patients with high CYTH4 expression had poor overall survival (OS; HR=2.19; 95% CI, 1.40-3.44; P=0.0006; high vs. low) and event-free survival (EFS; HR=2.32; 95% CI, 1.43-3.75; P=0.0006; high vs. low), and these patients could benefit from transplantation (HR=0.29; 95% CI, 0.18-0.47; P<0.0001; transplantation vs. chemotherapy). Multivariate analysis showed that high CYTH4 expression was independently associated with inferior OS (HR=2.49; 95% CI, 1.28-4.83; P=0.007) and EFS (HR=2.56; 95% CI, 1.48-4.42; P=0.001). Functional analysis showed that CYTH4 was involved in immunoregulation. In vitro validation showed knockdown of CYTH4 adversely affected cell growth and induced cell apoptosis, while overexpression of CYTH4 enhanced cell growth. Taken together, CYTH4 is expressed at high levels in AML and can potentially function as a prognostic biomarker.
