LDH-L

Elevated LDH levels before starting the Stupp protocol are clinically significant as they predict poorer overall survival and progression-free survival in glioblastoma patients and worse RR. Incorporating LDH measurements into treatment planning can help identify patients at higher risk of poor outcomes, allowing for more tailored and potentially aggressive treatment strategies to improve management and therapeutic responses in glioblastoma.

PV-E and TF-E priming effectively enabled hASCs to combat thermal injury by significantly promoting cell survival than untreated cells. Hence, these findings suggest that PV-E and TF-E priming could be used to attain improved cellular responses and enhanced therapeutic efficacy in burnt tissue.

Collectively, our findings emphasize the pivotal role of ALDH-LDHA-mTORC1 cascade in the proliferation of endometrial cancer. Targeting the interaction between mTORC1 and ALDH-influenced glycolysis holds promise for developing novel strategies to combat this aggressive cancer.

In summary, our study revealed diverse tumour cell profiles in OSCC tissues, with varying CSC and E-cadherin marker patterns across primary tumours and metastatic sites. Given the pivotal role of reduced survival rates as an indicator of unfavourable prognosis, the immunohistochemistry profile identified as CSChighE-cadherinlow at the ITF of primary tumours, emerges as a preferred prognostic marker closely linked to adverse outcomes in OSCC.

Our study provided a comprehensive analysis of the LDHs and illustrated low LDHB expression could inhibit tumor cell proliferation and ATP production by influencing metabolism, with improved immune cell infiltration and better response to immunotherapy.

High-36 cells and Low-8 cells represent novel gastric CSCs/CICs and non-CSCs/CICs, respectively. ALDHhigh CSCs/CICs evade T cells due to lower expression of HLA class 1.

TN-MF is invariably associated with significantly decreased survival and more aggressive clinical behavior with higher rates of leukemic transformation and shorter duration of response to ruxolitinib. Mutations impacting RNA splicing, epigenetic modification and signaling (SRSF2, SETBP1, IDH2, CBL, and GNAS) are more common in TN-MF, which likely drive its aggressive course and may account for suboptimal responses to JAK inhibition.

Combined treatment with pirfenidone and PD-L1 inhibitor significantly inhibits the progression of bladder cancer in mice possibly by regulating tumor immune microenvironment and inhibiting epithelial-mesenchymal transition of the tumor cells.

In our meta-analysis, different immune checkpoint factors were associated with different prognoses in HNSCC patients receiving immunotherapy. HPV, PD-L1, BMI, Alb, HPD, PS, GPS/mGPS, LDH, NLR, and PLR predicted the ICI outcome in HNSCC patients.

A total of 25 patients were evaluated. The median age at diagnosis was 66 years and 40% were female (10). 17 patients had low-grade FL (68%), six had WHO 3a high-grade FL (24%), and two had transformed high-grade FL (8%).

The median OS for LDH-4 dominant at the time of metastasis was 10.9 months, significantly shorter than other isozyme types (P=0.0134). Conclusions LDH-4 dominant isozyme pattern at time of recurrence has a short OS, proposing as a prognostic predictor in mRCC.

Patients received lymphodepletion with fludarabine (90 mg/m2) and cyclophosphamide (900 mg/m2) followed by 0.1-1 (CLL) and 0.5-5 (RT) x10e6 CART19 cells/kg in single or fractionated administration (10%, 30% and 60%) in a single institution...At screening patients had a median age of 58 years (44-74), 47% were females, with a median of 4 prior lines of therapy (2-9) including ibrutinib (89%), venetoclax (53%), R-CHOP (58%) and allo-HCT (21%)...Tocilizumab and corticosteroids were administered in 44% and 17% of patients, respectively... Administration of the CART19 var-cel (ARI-0001) was feasible in 95% of CLL/RT patients, with robust and durable var-cel engraftment in 89% of treated patients, and durable complete responses observed in 61% of patients. These initial outcomes or var-cel in this population contrasts with the overall findings of CART19 therapy in CLL/RT and encourages to further develop var-cel on this high-risk population.

Within pts with a CKT receiving HSCT, we identified additional prognostic factors including the presence of ≥5 cytogenetic aberrations. These pts are in urgent need for novel post HSCT approaches.

Particularly, we identified the molecular subgroup with unfavorable prognosis (A53) for which different clinical approach should be warranted. This classification will refine the patient prognostication and stratification in nTFHL.

Higher PD-L2 signature might be associated with a better response to Lu-PSMA therapy and warrants further studies investigating additional immunotherapy. In contrast, PD-L1 was not associated with outcome. The protective effect of PD-L2 signature might be present only in men with lower LDH levels.

Median OS for LDH-4 dominant at the time of metastasis was 10.9 months, significantly shorter than other isozyme types (P=0.0134). Conclusions LDH-4 dominant isozyme pattern at time of recurrence has a short OS, proposing as a prognostic predictor in mRCC.

Our findings indicated that a high level of serum LDH was associated with inferior OS in patients with BC. However, caution must be taken before recommendations are given because this interpretation is based upon very few clinical studies and a small sample.

In conclusion, our study revealed that LDHD might be an effective predictor of prognosis and immune filtration, possibly leading to better choices for immunotherapy.

Further TIMER2 and TISIDB analyses demonstrated that LDHA and LDHB expression was significantly related to multiple immune cells and immune inhibitors in over 500 ccRCC patients. These findings revealed that LDHB was an independent favorable predictor, and LDHA and LDHB correlated with tumor immune infiltrates in ccRCC patients, which indicated LDHA/LDHB could be implicated in the tumorigenesis of ccRCC and might be potential therapeutic targets for patients with ccRCC.

Increased fat reserves assessed by BMI, CRP, LDH, and interval between initial diagnosis and RLT, but not CT-derived body composition parameters, were relevant predictors for OS. As BMI can be altered, future research should investigate whether a high-calorie diet before or during PSMA RLT may improve OS.

Importantly, despite similar clinical profile, prolonged post-progression survival characterized oligoAR vs sysAR (median OS not reached vs 11.3 mos.; HR: 0.21, 95% CI: 0.08-0.59; P = 0.001). Conclusions The longitudinal analysis of blood immune hallmarks intersected with clinicopathological features may decipher the distinct patterns of AR in ICI-treated NSCLC patients.

Table: 1121P Conclusions Our results suggest that the IFNg-signature could become a biomarker for treatment decisions in LDH low patients directing towards anti-PD1 monotherapy (in IFNg high patients) versus combination therapy, with either anti-LAG3 or anti-CTLA-4 in IFNg low patients. However, confirmation in larger cohorts and in other combination therapies is needed.

In vitro, low ALDH2 levels showed reduced response to 5-fluorouracil in HNSC-derived cell lines...We also found ALDH2 is involved in regulating the immune response of the tumor microenvironment, and high levels of ALDH2 in bulk HNSC may enhance antitumor immunity, which could improve prognosis. These findings suggest that ALDH2 could be a potential biomarker in improving risk stratification and tailoring treatment strategies in HNSC patients, especially in the HPV-unrelated subgroup.

RNA sequencing confirmed and validated that ALDHHigh cells have a progenitor cell phenotype and provided evidence that the main isoform in this fraction is ALDH1A1, which was confirmed by immunohistochemistry. This demonstrates that ALDH activity, which marks hematopoietic progenitors and stem cells in diverse malignant tumors, also typifies native, blood vessel resident mesenchymal stem cells.

Pretreatment serum LDH level may be a reliable factor in predicting the therapeutic effect of chemoradiotherapy in ESCC. Further validation is needed before this model can be widely used in clinical practice.

In addition, we evaluated the combination of CRP and LDH, and univariate analyses showed that patients with high CRP and low LDH exhibited significantly better PFS than those in the other groups. Baseline levels of serum CRP and LDH have the potential to become a convenient clinical tool to predict response to immunotherapy in advanced non-small cell lung cancer.

LncRNA MALAT1 is up-regulated in CLL. However, high MALAT1 expression is associated with several favorable prognostic markers (high hemoglobin, low LDH, early clinical stages, negative CD38 status), as well as longer OS. The exact mechanisms of MALAT1 function in CLL pathogenesis and/or progression remain to be determined.

BRT produced significant cytoreduction in diameter, SUV, MTV, and LDH, all predictors of poor post-CAR T outcomes. Similar progression-free and overall survival in patients with initially low MTV and those who newly achieved low MTV after BRT suggest BRT may "convert" poor-risk patients to better risk. In the future, response to BRT may allow for risk stratification and individualization of bridging strategies.

We report age, sex, alcohol consumption, UV exposure, and the frequency of ALDH2 rs671 polymorphism in melanoma patients and therapeutic response to ICI. We are further analyzing the data and comparing them to other cohorts.

Six patients were identified with biopsy-confirmed false-positive [18F]FDG-PET/CT scans after CAR T-cell infusion (axicabtagene ciloleucel)... These findings highlight that inflammatory reactions such as SLR and HR can occur after CAR T-cell therapy and should be considered as potential causes of enhanced [18F]FDG-uptake, to prevent misclassification of response and unnecessary treatment. More insight into these inflammatory reactions is needed to distinguish them from recurrent or residual disease and to further optimize treatment.

In addition, we showed the relationship between ALDH2 expression and chemotherapeutic drug sensitivity. In conclusion, this study identified ALDH2 as a prognostic marker, associated with CD8+ T cell infiltration in HNSC.

Ingenuity pathway analysis of the proteomic datasets indicated that DEPs were associated with mitochondrial dysfunction, sirtuin signaling, oxidative phosphorylation and nucleotide excision repair. Our proteomics study predicts that high ALDH1A1 activity may be involved in these cellular pathways to promote a metabolic switch and cellular survival of CSCs.

Bulky disease post-CAR T is the most significant prognostic factor that can independently predict survival outcomes among HGBCL patients treated with CAR T-cell therapy.

Materials/ A retrospective study was conducted for consecutive HGBCL patients who received either tisagenlecleucel (tisa-cel) or axicabtagene ciloleucel (axi-cel) CAR T-cell therapy between 2017 and 2021 at a single institution. Bulky disease post-CAR T is the most signifi cant prognostic factor that can independently predict survival outcomes among HGBCL patients treated with CAR T-cell therapy.

In conclusion, the 3 hub genes (ALDH1A2, CLDN4 and GPR37) identified through bioinformatics analyses in the present study may serve as OC prognosis biomarkers. The study findings offer valuable insights into OC progression and mechanisms.

Low activity of acetaldehyde dehydrogenases in livers correlates with poor prognosis and clinical progression in hepatocel- lular carcinoma patients, and both gene polymorphisms and content influence its metabolic activity.

In our study, LDH levels at diagnosis were strongly correlated with the prognosis, and they might be considered a prognostic factor in Ewing sarcoma. The LDH value, along with its very low cost and its reproducibility in almost all centers, make it suitable as a potential prognostic biomarker in clinical practice.

The results of this study indicated that a comprehensive evaluation of BM features, clinical phenotypes, haematologic parameters, and molecular profiles is needed for the accurate diagnosis and treatment of ET, pre-PMF, and overt PMF patients.

Overexpression of LDH5, an event directly related to HIF1α overexpression, characterizes a third of breast tumors, which is more frequent in TNBC. Both HIF1α and LDH5 define cold breast cancer microenvironment and poor prognosis. A rational is provided to study further whether metabolic manipulations targeting HIF and LDH5 may enhance the antitumor immune response in breast cancer.

When the patients were classified into ALDH7A1-high and -low-expression groups, the high-ALDH7A1 group had superior outcomes in progression-free survival than the low-ALDH7A1 group (5-year survival of 58.7% vs. 48.0%, P = 0.048) did. In conclusion, patients with high ALDH7A1 expression might, however, have more favorable prognoses than those with low ALDH7A1 expression have.

In mCRPC patients treated with [Lu]Lu-PSMA I&T, baseline CRP, LDH, AST, and time interval until RLT initiation (thereby reflecting a possible indicator for tumor aggressiveness) are independently associated with survival. Our findings are in line with previous findings on [Lu]Lu-PSMA-617, and we believe that these clinical baseline characteristics may support the nuclear medicine specialist to identify long-term survivors.
