Patients with chronic lymphocytic leukemia (CLL) bearing TP53 mutations experience chemorefractory disease and are therefore candidates for targeted therapy. However, the significance of low-burden TP53 mutations with <10% variant allele frequency (VAF) remains a matter for debate. Herein, we describe clonal evolution scenarios of low-burden TP53 mutations, the clin. impact of which we analyzed in a “real-world” CLL cohort. TP53 status was assessed by targeted next-generation sequencing (NGS) in 511 patients entering first-line treatment with chemo- and/or immunotherapy and 159 patients in relapse before treatment with targeted agents. Within the pretherapy cohort, 16% of patients carried low-burden TP53 mutations (0.1% to 10% VAF). Although their presence did not significantly shorten event-free survival after first-line therapy, it affected overall survival (OS). In a subgroup with TP53 mutations of 1% to 10% VAF, the impact on OS was observed only in patients with unmutated IGHV who had not received targeted therapy, as patients benefited from switching to targeted agents, regardless of initial TP53 mutational status. Anal. of the clonal evolution of low-burden TP53 mutations showed that the highest expansion rates were associated with fludarabine, cyclophosphamide, and rituximab regimen in both first- and second-line treatments (median VAF increase, 14.8x and 11.8x, resp.) in contrast to treatment with less intense treatment regimens (1.6x) and no treatment (0.8x). In the relapse cohort, 33% of patients carried low-burden TP53 mutations, which did not expand significantly upon targeted treatment (median VAF change, 1x). Sporadic cases of TP53 mutations clonal shifts were connected with the development of resistance-associated mutations. Altogether, our data support the incorporation of low-burden TP53 variants in clin. decision making.

The potential efficacy and mechanism of bendamustine in entra-nodal NK/T cell lymphoma was written by Gao, Yuyang;Feng, Xiaoyan;Song, Wenting;Li, Hongwen;Shi, Cunzhen;Jin, Mengyuan;Li, Zhaoming;Zhang, Lei;Zhang, Mingzhi. And the article was included in Hematological Oncology in 2022.Reference of 16506-27-7 The following contents are mentioned in the article:

Bendamustine has been shown to have anti-tumor activities in hematol. malignancies, but the role of bendamustine in natural killer (NK)/T cell lymphoma (NKTCL) treatment is unclear. Our study has shown that bendamustine had potent growth-inhibitory and apoptosis-inducing effects on NKTCL cells. Interestingly, we noticed that the combination of either gemcitabine or etoposide results in additive or synergistic cytotoxicity. Bendamustine induced mitochondria-mediated apoptosis in concentration- and time-dependent manners in NKTCL cells, shown as down-regulation of Bcl-2 and activation of cleavage of caspases 3, 7, 9 and poly adenosinediphosphate-ribose polymerase (PARP). Bendamustine arrested NKTCL cells in G2/M phase, with downregulation of expression of cyclin B1 and upregulation of expression of p-cdc2, p-cdc25c and p-P53. Furthermore, we confirmed that bendamustine activated DNA damage response (DDR) directly or through Ataxia Telangiectasia Mutated Protein (ATM)/Chk2 and ATR/Chk1 pathway and increased the intracellular reactive oxygen species (ROS) level in NKTCL cells, which caused G2/M phase arrest and apoptosis. Bendamustine also inhibited phosphorylation of transcriptional factor STAT3, contributing to cell apoptosis and proliferation inhibition. Finally, we verified the effect of bendamustine on NKTCL cells in vivo. It showed that bendamustine dramatically inhibited the growth of the s.c. tumor, with no obvious impact on mice weight These findings demonstrate that bendamustine activates DDR pathway, induces the accumulation of intracellularROS level as well as inhibition of STAT3, leading to cell apoptosis and G2/M cell cycle arrest in NKTCL cells, which indicates that bendamustine dramatically suppressed NKTCL both in vitro and in vivo and provides a potential therapeutic strategy in the treatment of NK/T lymphoma.

Bendamustine is a standard treatment for low-grade B-cell lymphomas, and considered safe in clin. trials. Its safety in routine practice might be different. We retrospectively analyzed the infection complications in an unselected cohort of patients treated with bendamustine over a nine-year period. Patients were regularly monitored for blood counts and cytomegalovirus (CMV) reactivation by antigen assay and polymerase chain reaction. They received granulocyte colony stimulating factor for neutropenia, and routine anti-pneumocystis and optional anti-fungal prophylaxis. There were 179 men and 127 women at a median age of 61.5 (20-90) years, 52% receiving bendamustine for relapsed/refractory disease. Malignancies included low-grade B-cell lymphomas (54%), myeloma (10%), T-cell lymphomas (11%), Hodgkin lymphoma (2%) and other lymphoid neoplasms (23%). Most patients had good performance status (Eastern Cooperative Oncol. Group score: 0-1, 72%). CMV reactivation occurred in 58 patients (19%) at a median age of 68 (39-85) years. Univariate anal. showed CMV reactivation to be significantly associated with elevated lactate dehydrogenase (P = 0.045), decreased albumin (P = 0.003) and older age (reactivation vs. no reactivation: 66.3 ± 11.4 vs. 59.4 ± 14.5 years, P = 0.0016). Age remained the only significant risk on multivariate anal. CMV reactivation resulted in retinitis (N = 4), ependymitis/ventriculitis (N = 1) and duodenitis/colitis (N = 1). Invasive fungal disease occurred in five patients (candidemia, N = 2; aspergillosis N = 1; cryptococcemia, N = 1; scedosporiosis, N-1). Nineteen patients had culture pos. septicemia. Our observations showed that even with a vigorous anti-infective strategy, bendamustine treatment was still associated with significant risks of bacterial and opportunistic viral and fungal infections.

Chemotherapy for non-Hodgkin lymphoma in the hemodialysis patient: A comprehensive review was written by Yasuda, Hajime;Yasuda, Mutsuko;Komatsu, Norio. And the article was included in Cancer Science in 2021.Safety of 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid The following contents are mentioned in the article:

A review. Chemotherapy for non-Hodgkin lymphoma (NHL) in the hemodialysis (HD) patient is a challenging situation. Because many drugs are predominantly eliminated by the kidneys, chemotherapy in the HD patient requires special considerations concerning dose adjustments to avoid overdose and toxicities. Conversely, some drugs are removed by HD and may expose the patient to undertreatment, therefore the timing of drug administration in relation to HD sessions must be carefully planned. Also, the metabolites of some drugs show different toxicities and dialysability as compared with the parent drug, therefore this must also be catered for. However, the pharmacokinetics of many chemotherapeutics and their metabolites in HD patients are unknown, and the fact that NHL patients are often treated with distinct multiagent chemotherapy regimens makes the situation more complicated. In a realm where uncertainty prevails, case reports and case series reporting on actual treatment and outcomes are extremely valuable and can aid physicians in decision making from drug selection to dosing. We carried out an exhaustive review of the literature and adopted 48 manuscripts consisting of 66 HD patients undergoing 71 chemotherapy regimens for NHL, summarized the data, and provide recommendations concerning dose adjustments and timing of administration for individual chemotherapeutics where possible. The chemotherapy regimens studied in this review include, but are not limited to, rituximab, cyclophosphamide + vincristine + prednisolone, and cyclophosphamide + doxorubicin + vincristine + prednisolone-like regimens, chlorambucil, ibrutinib, bendamustine, methotrexate, platinum compounds, cytarabine, gemcitabine, etoposide, ifosfamide, melphalan, busulfan, fludarabine, mogamulizumab, brentuximab vedotin, and 90Y-ibritumomab tiuxetan.

Prognostic model of eleven genes based on the immune microenvironment in patients with thymoma was written by Yang, Ying;Xie, Liqing;Li, Chen;Liu, Liangle;Ye, Xiuzhi;Han, Jianbang. And the article was included in Frontiers in Genetics in 2022.Recommanded Product: 16506-27-7 The following contents are mentioned in the article:

The pathogenesis of thymoma (THYM) remains unclear, and there is no uniform measurement standard for the complexity of THYM derived from different thymic epithelial cells. Consequently, it is necessary to develop novel biomarkers of prognosis estimation for patients with THYM. Consensus clustering and single-sample gene-set enrichment anal. were used to divide THYM samples into different immunotypes. Differentially expressed genes (DEGs) between those immunotypes were used to do the Kyoto Encyclopedia of Genes and Genomes anal., Gene Ontol. annotations, and protein-protein interaction network. Furthermore, the survival-related DEGs were used to construct prognostic model with lasso regression. The model was verified by survival anal., receiver operating characteristic curve, and principal component anal. Furthermore, the correlation coefficients of stemness index and riskscore, tumor mutation burden (TMB) and riskscore, drug sensitivity and gene expression were calculated with Spearman method. THYM samples were divided into immunotype A and immunotype B. A total of 707 DEGs were enriched in various cancer-related or immune-related pathways. An 11-genes signature prognostic model (CELF5, ODZ1, CD1C, DRP2, PTCRA, TSHR, HKDC1, KCTD19, RFX8, UGT3A2, and PRKCG) was constructed from 177 survival-related DEGs. The prognostic model was significantly related to overall survival, clin. features, immune cells, TMB, and stemness index. The expression of some genes were significantly related to drug sensitivity. For the first time, a prognostic model of 11 genes was identified based on the immune microenvironment in patients with THYM, which may be helpful for diagnosis and prediction. The associated factors (immune microenvironment, mutation status, and stemness) may be useful for exploring the mechanisms of THYM.

Resistance to obinutuzumab-induced antibody-dependent cellular cytotoxicity caused by abnormal Fas signaling is overcome by combination therapies was written by Kawasaki, Natsumi;Yamashita-Kashima, Yoriko;Fujimura, Takaaki;Yoshiura, Shigeki;Harada, Naoki;Kondoh, Osamu;Yoshimura, Yasushi. And the article was included in Molecular Biology Reports in 2022.Formula: C16H21Cl2N3O2 The following contents are mentioned in the article:

Obinutuzumab, a Type II anti-CD20 antibody, is used to treat follicular lymphoma. A major mode of action of obinutuzumab is antibody-dependent cellular cytotoxicity (ADCC). Knowledge of the mechanisms of resistance to obinutuzumab is important for the development of next-line strategies to follow obinutuzumab-containing therapy, including obinutuzumab retreatment. Unfortunately, the mechanisms by which tumor cells acquire resistance to ADCC are still poorly understood. To address this, we examined the mechanisms of resistance to obinutuzumab-induced ADCC and the combination efficacy of obinutuzumab and clin. available agents in the established resistant cells. Methods and results: We established cells resistant to obinutuzumab-induced ADCC using the non-Hodgkin lymphoma cell line RL and examined their mechanisms of resistance and the combination efficacy of obinutuzumab and clin. available agents. Comprehensive anal. by RNA sequencing of resistance mechanisms revealed that abnormal Fas signaling decreased sensitivity to ADCC in resistant clones. Combination treatment with prednisolone, a component of CHOP and CVP, was found to enhance ADCC sensitivity of RL cells and resistant clones and to significantly suppress tumor growth in xenograft models. Treatment with prednisolone upregulated expression of CD20 and an apoptosis-inducing protein BIM, which might augment perforin/granzyme B-mediated cell death. Furthermore, pretreatment of the effector cells with bendamustine enhanced ADCC activity, and treatment with obinutuzumab plus bendamustine showed significant antitumor efficacy in xenograft models. It was speculated that bendamustine upregulates ADCC activity by potentiating granules-mediated cell killing. Our study revealed a novel mechanism underlying obinutuzumab-induced ADCC resistance and indicated that ADCC resistance could be overcome by combining obinutuzumab with prednisolone or bendamustine. This study provides a scientific rationale for obinutuzumab-retreatment in combination with clin. available chemotherapeutic agents for obinutuzumab resistant follicular lymphoma.

Chimeric antigen receptor T cell (CAR-T) therapy has emerged as highly effective in relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL), but only about 40% patients have achieved sustained responses. Here, we conducted a phase II clin. trial testing efficacy and toxicities of CAR-T therapy in R/R non-Hodgkin’s lymphoma patients (NCT03196830). Among enrolled patients, 33 R/R DLBCL patients pretreated with DFC (decitabine, fludarabine plus cyclophosphamide) lymphodepletion chemotherapy and infused with tandem CD19-CD22 based CAR-T cells were drawn out for efficacy and toxicities of CAR-T therapy evaluation. With a median follow-up of 10.9(0.6-29.0) months, the best overall response and complete remission (CR) rates were 90.9% and 63.6%, resp. The median progression-free survival (PFS) was 10.2 mo and overall survival (OS) was undefined. The 2- year OS and PFS rates were 54.3% and 47.2%, resp. No severe grade 4 cytokine release syndrome (CRS) was observed and grade 3 CRS was observed in only 7 patients; 3 patients developed mild immune effect or cell-associated neurotoxic syndrome. All toxicities were transient and reversible and no CART-related mortality. Further subgroup anal. showed that achieving CR was an independent prognostic factor associated with favorable PFS and OS. The 2- year OS and PFS for patients who achieved CR within 3 mo (undefined vs. undefined P = 0.021 and undefined vs. undefined P = 0.036) or during the follow-up period were significantly longer than those who did not (undefined vs. 4.6 mo P < 0.0001 and undefined vs. 2.0months P<0.001). While severe CRS was also an independent prognostic factor but associated with inferior PFS and OS. The 2-yr OS and PFS for patients with grade 3 CRS were significantly shorter than those with grade 0-2 CRS (4.1 mo vs. undefined P<0.0001 and 1.7 mo vs. undefined P = 0.0002). This study indicated that CD19/CD22 dual-targeted CAR-T therapy under a decitabine-containing lymphodepletion regimen may be a safe, potent effective approach to R/R DLBCL patients.

Amyotrophic lateral sclerosis is a fatal progressive disease with a still unclear multi-factorial etiol. This study focused on the potential relationship between drug exposure and the development of amyotrophic lateral sclerosis by performing a detailed anal. of events reported in the FDA Adverse Event Reporting System database. The FDA Adverse Event Reporting System quarterly data (Jan. 2004-June 2020) were downloaded and deduplicated. The reporting odds ratios and their 95% confidence intervals were calculated as a disproportionality measure. The robustness of the disproportion was assessed accounting for major confounders (i.e., using a broader query, restricting to suspect drugs, and excluding reports with amyotrophic lateral sclerosis as an indication). Disproportionality signals were prioritized based on their consistency across analyses (reporting odds ratio stability). We retained 1188 amyotrophic lateral sclerosis cases. Sixty-two drugs showed significant disproportionality for amyotrophic lateral sclerosis onset in at least one anal., and 31 had consistent reporting odds ratio stability, including tumor necrosis factor-alpha inhibitors and statins. Disproportionality signals from ustekinumab, an immunomodulator against interleukins 12-23 used in autoimmune diseases, and the anti-IgE omalizumab were consistent among analyses and unexpected. For each drug emerging as possibly associated with amyotrophic lateral sclerosis onset, biol. plausibility, underlying disease, and reverse causality could be argued. Our findings strengthened the plausibility of a precipitating role of drugs primarily through immunomodulation (e.g., tumor necrosis factor-alpha, ustekinumab, and omalizumab), but also by impacting metabolism and the musculoskeletal integrity (e.g., statins and bisphosphonates). Complement and NF-kB dysregulation could represent interesting topics for planning translational mechanistic studies on amyotrophic lateral sclerosis as an adverse drug effect.

Studies suggest that immune checkpoint inhibitors may represent a promising strategy for boosting immune responses and improving the antitumor activity of standard therapies in patients with relapsed/refractory hematol. malignancies. Phase 1/2 FUSION NHL 001 was designed to determine the safety and efficacy of durvalumab, an anti-programmed death ligand 1 (PD-L1) antibody, combined with standard-of-care therapies for lymphoma or chronic lymphocytic leukemia (CLL). The primary endpoints were to determine the recommended phase 2 dose of the drugs used in combination with durvalumab (durvalumab was administered at the previously recommended dose of 1500 mg every 4 wk) and to assess safety and tolerability. Patients were enrolled into one of four arms: durvalumab monotherapy (Arm D) or durvalumab in combination with lenalidomide ± rituximab (Arm A), ibrutinib (Arm B), or rituximab ± bendamustine (Arm C). A total of 106 patients with relapsed/refractory lymphoma were enrolled. All but two patients experienced at least one treatment-emergent adverse event (TEAE); those not experiencing a TEAE were in Arm C (diffuse large B-cell lymphoma [DLBCL]) and Arm D (DLBCL during the durvalumab monotherapy treatment period). No new safety signals were identified, and TEAEs were consistent with the resp. safety profiles for each study treatment. Across the study, patients with follicular lymphoma (FL; n = 23) had an overall response rate (ORR) of 59%; ORR among DLBCL patients (n = 37) was 18%. Exploratory biomarker anal. showed that response to durvalumab monotherapy or combination therapy was associated with higher interferon-γ signature scores in patients with FL (p = .02). Durvalumab as monotherapy or in combination is tolerable but requires close monitoring. The high rate of TEAEs during this study may reflect on the difficulty in combining durvalumab with full doses of other agents. Durvalumab alone or in combination appeared to add limited benefit to therapy.

Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is one of the most frequent types of leukemia/lymphoma in adults in Western countries. However, there are few studies regarding its epidemiol. and treatment patterns in Asian countries. To investigate CLL/SLL in Asian populations, we identified CLL/SLL patients diagnosed during 2006 to 2015 from the Taiwan Cancer Registry Database and estimated the incidence. Further, patients diagnosed during 2008 to 2015 were included for the anal. of treatment patterns and survivals. Treatments for CLL/SLL were retrieved from the Taiwan’s National Health Insurance Research Database and survival data from the National Death Registry. In total, 1497 patients who were older than 20 years and had newly diagnosed CLL/SLL during 2006-2015 were identified. The age-standardized incidence rates of CLL/SLL (0.36 per 100 000 persons in 2006, and 0.54 in 2015) increased during the 10-yr period. The sex ratio was ranged from 1.21 to 2.63 with male predominant during 2006 and 2015. For the anal. of treatment patterns (n = 1236), 72.8% patients received chemotherapies. The median duration between the diagnosis and start of treatments was 27 days, and monotherapy of chlorambucil, bendamustine or cyclophosphamide was the most common regimen in initial treatments. The median follow-up duration for the patients receiving therapies was 29.6 mo, and 45.0% patients experienced relapse or refractory. In patients with relapse/refractory CLL/SLL, 34.1% received rituximab-containing chemotherapies. Three hundred and ninety-nine (32.3%) patients received intensive treatments, and 175 (43.9%) of them received rituximab-containing chemotherapies. The 5-yr overall survival (OS) rate was 61%, and age was an important prognostic factor for CLL/SLL patients. This study is the first population-based study in Asia and provides comprehensive evidence of epidemiol., treatment patterns and survivals of CLL/SLL in an Asian population. This study involved multiple reactions and reactants, such as 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7Application In Synthesis of 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid).

4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7) belongs to imidazole derivatives. The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with a Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Application In Synthesis of 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid
