Prevention and Treatment of Glucocorticoid-Induced Osteoporosis in adults: Recommendations From the European Calcified Tissue Society

Abstract Introduction This report presents the recommendations of the European Calcified Tissue Society (ECTS) for the prevention and treatment of glucocorticoid-induced osteoporosis (GIOP) in adults. Our starting point was that the recommendations be evidence based, focused on non-bone specialists who treat patients with GC and broadly supported by ECTS. Methods The recommendations were developed by global experts. After a comprehensive review of the literature, twenty-five recommendations were formulated, based on quality evidence. For stratifying fracture risk and the most appropriate first line of treatment, we have classified patients into 3 categories: those at medium risk of fractures i.e. adults without a recent (in the last 2 years) history of fracture, those at high risk of fractures i.e. adults with recent history of fracture, and/or at least one vertebral fracture (grade ≥ 2 according to Genant classification), and those at very high risk of fractures i.e. adults aged ≥ 70 years with a recent hip fracture, pelvis fracture, and/or at least one vertebral fracture (grade ≥ 2 according to Genant classification) . The subtopics in the recommendations include Who to assess, How to assess, Who to treat, How to treat, and Follow-up and Monitoring. Results General measures are recommended for all patients who are being prescribed glucocorticoids (GCs) for > 3 months: i.e. calcium and protein intake should be normalized, a 25(OH) vitamin D concentration of 50-125 nmol/L should be attained, and the risk of falls be minimized. 1)Who to assess? (R1-2) A preliminary assessment of fracture risk should be routinely performed in patients likely to receive oral GCs for ≥ 3 months: (i) women and men ≥ 50 years and (ii) patients at increased risk of fracture (history of fragility fracture and/or have comorbidities or are on medications that are frequently associated with osteoporosis. 2)How to assess (fracture risk)? (R3-6) Clinical risk factors including history of fragility fracture, systematic vertebral imaging, and GCs dose-adjusted FRAX, measurement of BMD by DXA, fall risk, and biochemical testing. 3) Who to treat? (R7-12) Anti-osteoporosis treatment is indicated for women and men ≥ 50 years with (i) the presence of a recent history of vertebral and/or non-vertebral fracture (less than 2 years) (ii)and/or a GCs dosage ≥ 7.5 mg/day, (iii)and/or age ≥ 70 years (iv)and/or a T-score ≤ -1.5, (v)and/or 10-year probability risk above the country specific GC dose-adjusted FRAX® thresholds. In premenopausal women and men < 50 years with a Z-score ≤ -2 and/or a history of fragility fracture, it is recommended to refer the patient to a bone specialist. 4) How to treat? (R13-18) In women and men ≥ 50 years, (i) alendronate or risedronate is preferred as the first line of treatment in patients at medium risk of fractures, (ii) zoledronic acid or denosumab in patients at high risk of fractures, and (iii) teriparatide in patients at very high risk of fractures. It is imperative that sequential therapy be implemented in individuals receiving denosumab or teriparatide as their first-line treatment regimen. 5) Follow-up and Monitoring (R19-25): In patients receiving anti-osteoporosis treatment, monitoring of clinical risk factors (e.g., history of fragility fracture), systematic vertebral imaging, fall risk, BMD measurement using DXA, and biochemical testing should be performed regularly during follow-up. Conclusions The new, evidence-based recommendations by the ECTS for the prevention and treatment of GIOP provide clear and pragmatic advice to all health practitioners especially those who are not bone specialists.

Efficacy and safety of systemic treatment for progressive and refractory desmoid tumor: a systematic review and Bayesian network meta-analysis.

Desmoid tumors (DT) are rare, locally invasive tumors originating from connective tissue. Surgical intervention is no longer the standard treatment for DT, as systemic therapy gradually replaces it due to its superior efficacy. Despite the availability of various treatment modalities, there is a need for a first-line systemic treatment regimen that offers both effective disease control and acceptable safety profiles. To assess the efficacy and safety of different systemic treatment agents for DT, we conducted a systematic review and network meta-analysis. Eligible studies were identified through searches of PubMed, Embase, and the Cochrane Library databases, and data were extracted according to predefined inclusion criteria. Three articles and clinical data from 295 patients with progressive and refractory DT were included in this Bayesian network meta-analysis. When considered by objective response rate (ORR), the efficacy of γ-secretase inhibitor versus placebo (OR 0.12, 95%CI 0.01-1.68) is superior to that of TKI (OR 0.49, 95%CI 0.03-7.62) and chemotherapy (OR 0.90, 95%CI 0.02-40.00). Vascular endothelial growth factor (VEGF)-TKI (OR, 0.09; 95% CI, 0.01-1.79) seemed to have the highest improvement in terms of 1-yr PFS rate, while chemotherapy seemed to have the highest improvement across all therapies in terms of 2-yr PFS rate across all therapies (OR, 0.06; 95 percent CI, 0.01-2.98). In terms of safety, the incidence of AEs is highest for γ-secretase inhibitor versus placebo (OR 0.16, 95%CI 0.02-1.55), while TKI is associated with the least AEs (OR 0.62, 95%CI 0.06-6.97). γ-secretase inhibitor provides superior local control of tumors, while chemotherapy and TKI may offer better long-term survival benefits. Among the three regimens, TKI demonstrated better treatment-related safety. These findings have important implications for guiding clinical practice in systemic treatment of DT.

Efficacy of Bismuth Quadruple Therapy in the Treatment of Helicobacter pylori-Infected Peptic Ulcer Children in Vietnam.

The continuous increase in drug-resistant strains, the lack of novel antibiotics, and the fewer options available to combat antibiotic-resistant infections in pediatrics pose significant challenges to the eradication of Helicobacter pylori (H. pylori) in children. This study evaluated the efficacy of first-line therapy with bismuth quadruple therapy in H. pylori-positive pediatric patients with peptic ulcers. 136 patients (aged between 8 and 17 years) diagnosed with active peptic ulcers with H. pylori infection were enrolled in this study. Patients with H. pylori strain sensitive to tetracycline and metronidazole were assigned to bismuth quadruple therapy, including a proton pump inhibitor (PPI), bismuth, tetracycline, and metronidazole. Antibiotic resistance of H. pylori was analyzed by the Epsilometer test. Treatment efficacy was evaluated at 12 weeks based on H. pylori eradication and peptic ulcer healing rates. H. pylori infection status was evaluated by a 13C-urea breath test. Most isolates showed extremely high rates of resistance to commonly prescribed antibiotics used for children, including clarithromycin (97.0%) and amoxicillin (84.6%), while the low rate of resistance to levofloxacin (16.2%). The overall success rate of eradication therapy in the intention-to-treat and the per-protocol group were 86.0% and 89.3%, respectively. Peptic ulcer healing rates for total patients at 6 weeks and 12 weeks were 75.0% and 97.7%, respectively. There were no entail unpleasant adverse events, and peptic ulcer symptoms decreased steadily over time in all cases. The bismuth quadruple therapy with a 2-week PPI pretreatment and followed by prolonged PPI was highly successful in eradicating H. pylori infection and healing ulcers in pediatric patients with active peptic ulcer. This might be preferable as a first-line empiric treatment regimen for H. pylori-positive pediatric patients with peptic ulcers, especially in populations with high rates of resistance to amoxicillin and clarithromycin.

The progress of Mycobacterium tuberculosis drug targets.

Tuberculosis (TB) has been troubling humans for hundreds of years, is a highly infectious disease caused by Mycobacterium tuberculosis (Mtb) infection, Mtb can infect almost all organs of the body and is one of the deadly infectious diseases in the world. At present, the first-line treatment regimen has a long treatment cycle and is prone to multiple drug resistance. Anti-tuberculosis drugs and latent tuberculosis infection (LTBI) resistance are increasing year by year, and new targets and new bioactive compounds are urgently needed to treat this disease. This review focuses on the latest reported anti-TB drug targets and related compounds in recent years, reviews the current TB drug regimen and major defects, outlines the key drug targets developed to date in Mtb, and the current situation of newly discovered anti-TB resistant forms of drugs. To provide a reference for the research and development of new anti-TB drugs and bring new treatment strategies for TB patients.

Newer Therapies for Refractory Helicobacter pylori Infection in Adults: A Systematic Review.

Helicobacter pylori (H. pylori) infection is a global health concern, affecting approximately two-thirds of the world's population. Standard first-line treatment regimens often fail, necessitating alternative rescue therapies. This review aims to evaluate the efficacy and safety of newer treatment regimens in patients who have failed initial H. pylori eradication therapy. A comprehensive literature search was conducted in PubMed, the Cochrane Library, and Embase. Inclusion criteria were randomized controlled trials (RCTs) published after 2010, involving patients with previous H. pylori treatment failure and interventions with vonoprazan-based therapy, high-dose PPI-amoxicillin dual therapy (HDDT), or rifabutin-containing triple therapy. 10 RCTs were included. HDDT demonstrated high eradication rates (81.3% to 89.2%), particularly when combined with metronidazole (92.6%), although at an increased frequency of adverse events. Vonoprazan-based regimens achieved comparable or higher eradication rates (83.3% to 89.5%) compared to PPI-based therapies, with similar adverse events. Rifabutin-containing triple therapy showed high efficacy (80.7% to 100%), particularly in patients with a history of multiple treatment failures, and it was associated with lower adverse events compared to bismuth-containing regimens. HDDT, vonoprazan-based therapy, and rifabutin-based therapy have proven to be effective and safe rescue regimens for treating H. pylori infection. Additional large-scale randomized studies are needed to determine the optimal doses and durations of these regimens to achieve the highest eradication rate with the lowest incidence of adverse events among patients with refractory H. pylori infections globally.

Toxoplasma qPCR kinetics to guide pre-emptive treatment of toxoplasmosis after allogeneic hematopoietic stem cell transplantation.

Recent ECIL-guidelines recommend a quantitative PCR (qPCR) guided pre-emptive treatment approach to toxoplasmosis in seropositive recipients of allogeneic hematopoietic cell transplantation (allo-HCT). While qPCR might serve as a sensitive tool for early Toxoplasma detection, its role in treatment follow-up remains unknown. We analyzed the qPCR kinetics of allo-HCT recipients experiencing either Toxoplasma infection (TI, n=71) or disease (TD, n=14) in relation to different parameters. We included 85 patients with available qPCR values expressed as quantitative cycle (Cq) from four large hematological centers from 2009 to 2023, and kinetic analysis was performed in a selection of 74 patients screened at least weekly with blood qPCR. Day 0 (D0) was the day of anti-Toxoplasma treatment start or (when untreated) day of diagnosis. Time to qPCR negativity was inversely proportional to the Cq value at D0 (p=0.0063). Not reaching negativity at D10 was associated with a significantly higher mortality at D30 (p=0.023). Patients with a high D0-parasitic load and patients with TD showed slower clearance (p<0.001, p=0.032). Time to negativity was not significantly different for patients started on prophylactic vs curative doses as first-line treatment regimen (p=0.16). This study underscores the predictive value of qPCR kinetics monitoring in allo-HCT patients with toxoplasmosis. With the aforementioned risk factors, clinicians can identify patients at high-risk for worse outcome. Our results support to consider a therapeutic change or reinforcement if the parasitic load does not decrease after 10 days, supplementing existing clinical guidelines.

Comparative Efficacy and Safety of Potassium-Competitive Acid Blocker-Based Dual, Triple, and Quadruple Regimens for First-Line Helicobacter pylori Infection Treatment: A Systematic Review and Network Meta-Analysis.

In the last few years, numerous new potassium-competitive acid blocker (P-CAB)-based randomized controlled trials (RCTs) concerning the first-line regimens for Helicobacter pylori infection treatment from various countries have been published. However, no network meta-analysis (NWM) exists, which examines the comparative efficacy and safety of P-CAB-based dual, triple, and quadruple treatments, and, therefore, in this NWM, we examined this matter comparing efficacy and safety of these P-CAB-based regimens. Databases were searched for identification, screening, eligibility, and inclusion of relevant RCTs. Extracted data were entered into a Bayesian NWM, and the ranking order for each regimen was evaluated by means of the surface under the cumulative ranking area values. Twenty-five eligible RCTs were included with 7,605 patients randomized to 6 first-line regimens, i.e. P-CAB dual therapy, P-CAB triple therapy, P-CAB quadruple therapy, PPI dual therapy, PPI triple therapy, and PPI quadruple therapy. The surface under the cumulative ranking area values (%) for these 6 regimens were 92.7, 62.5, 33.9, 75.1, 19.4, and 16.3, respectively. The comparative effectiveness ranking showed that P-CAB dual therapy regimen ranked first for efficacy and last for adverse effects and had the best profile for integrated efficacy-safety. In this NWM concerning the comparative efficacy and safety of P-CAB-based dual, triple, and quadruple regimens for the first-line H. pylori infection treatment, the overall results showed that P-CAB-based dual treatment ranked first for efficacy with the best-integrated efficacy-safety profile. This is of importance, since the dual regimens overcome the crucial issue of clarithromycin resistance. Consequently, these findings are expected to be useful in helping clinical decision making and future guidelines.

Economic evaluation of NALIRIFOX vs. nab-paclitaxel and gemcitabine regimens for first-line treatment of metastatic pancreatic ductal adenocarcinoma from U.S. perspective

BackgroundThe cost-effectiveness of NALIRIFOX as a potential new standard of care for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) has yet to be established. Our objective was to evaluate the cost-effectiveness of NALIRIFOX vs. nab-paclitaxel and gemcitabine in this indication from the perspective of U.S. public payers.MethodsA partitioned survival model was constructed from the perspective of U.S. public payers, drawing on baseline patient characteristics and vital clinical data from the NAPOLI-3 trial. Costs and utilities were sourced from publicly accessible databases and literature. A lifetime horizon was applied, with an annual discount rate of 3%. We calculated and compared cumulative costs, life years, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICER). To evaluate the model’s robustness, sensitivity analyses, scenario analyses, and subgroup analyses were carried out. Additionally, a price simulation for the costly liposomal irinotecan was conducted to inform the pricing strategy at the given willingness to pay (WTP) threshold.ResultsIn the base-case analysis, NALIRIFOX provided an additional 0.29 QALYs with an ICER of $206,340.69 /QALY compared to nab-paclitaxel and gemcitabine, indicating it is not cost-effective at a $150,000/QALY threshold. Sensitivity analysis showed the model was most sensitive to the costs of liposomal irinotecan, capecitabine, and post-progression care. Probabilistic sensitivity analysis indicated a 17.66% probability of NALIRIFOX being cost-effective at $150,000/QALY, rising to 47.48% at $200,000/QALY. Pricing simulations suggested NALIRIFOX could become cost-effective at $150,000/QALY if the price of irinotecan liposome drops to $53.24/mg (a 14.8% reduction).ConclusionsNALIRIFOX may not be cost-effective at its current price as a first-line treatment for patients with mPDAC in the long term. The cost of liposomal irinotecan has the greatest impact. It may become cost-effective only if its cost is reduced by 14.8%, with a WTP threshold of $150,000 /QALY.

Efficacy and safety evaluation of first-line systemic treatments for unresectable esophageal squamous cell carcinoma: a network meta-analysis.

To evaluate the efficacy and safety of various first-line initial treatment systemic regimens for patients with unresectable esophageal squamous carcinoma(ESCC), utilizing a network meta-analysis approach. A comprehensive search for randomized controlled trials focusing on the primary treatment of esophageal cancer ESCC was conducted across multiple databases including PubMed, Embase, Cochrane Library, and Web of Science, up until November 17, 2023. The quality of the included studies was rigorously assessed using Review Manager software. Subsequently, data analysis was meticulously carried out employing R software. The first-line treatment regimens examined were: CD (Cisplatin + Docetaxel), CET-CF (Cetuximab + Cisplatin + Fluorouracil), CF (Cisplatin + Fluorouracil), N-CF (Nivolumab + Cisplatin + Fluorouracil), NI (Nivolumab + Ipilimumab), Nim-CF (Nimotuzumab + Cisplatin + Fluorouracil), P-CF (Pembrolizumab + Cisplatin + Fluorouracil), and Ser-CF (Serplulimab + Cisplatin + Fluorouracil). The Primary endpoints included the overall survival(OS),progression-free survival (PFS),objective response rate (ORR) and disease control rate (DCR).The secondary endpoint was adverse effects(AEs). The analysis encompassed eight studies, incorporating a total of 3,051 patients with untreated esophageal cancer. There are 45 people in the CD regimen,32 in the CET-CF regimen,1,212 in the CF regimen,447 in the N-CF regimen,456 in the NI regimen,53 in the Nim-CF regimen,447 in the P-CF regimen and 368 in the Ser-CF regimen. The network meta-analysis revealed that, in comparison to the CF regimen, the other regimens (CD, CET-CF, N-CF, NI, Nim-CF, P-CF, and Ser-CF) did not demonstrate a statistically significant impact on overall survival (OS) or progression-free survival (PFS). However, Ser-CF potentially offers superior outcomes in terms of OS and PFS when juxtaposed with other regimens. Notably, N-CF was associated with a substantial increase in the objective response rate (ORR), and CET-CF markedly improved the disease control rate (DCR). In terms of adverse effects, N-CF was more likely to cause anorexia, whereas CET-CF was significantly associated with nausea, vomiting, neutropenia, and skin disorders. The current evidence suggests that N-CF may provide the most favorable outcomes in terms of ORR, while CET-CF could be the optimal choice for enhancing DCR in patients with untreated esophageal cancer.

Real-world treatment costs of first-line treatment for metastatic colorectal cancer: a survey of the JCOG colorectal cancer study group.

Although treatment outcomes for metastatic colorectal cancer (mCRC) have dramatically improved over the past few decades, drug costs have also significantly increased. This study aimed to investigate which first-line treatment regimens for mCRC are actually used (frequency) in Japanese practice and at what cost. We collected data on patients with mCRC who received first-line treatment at 37 institutions of the Japan Clinical Oncology Group Colorectal Cancer Study Group from July 2021 to June 2022, and calculated the cost of regimens. The cost per month of each regimen was estimated based on standard usage, assuming a patient with a weight of 70kg and a body surface area of 1.8m2. We categorized the regimens into very high-cost (≥1 000 000 Japanese yen [JPY]/month), high-cost (≥500 000 JPY/month), and others (<500 000 JPY/month). The study included 1880 participants, 24% of whom were≥75years. Molecular targeted containing regimens were received by 78% of the patients. The most frequently used regimen was the doublet regimen (fluoropyrimidine with either oxaliplatin or irinotecan) plus bevacizumab (43%), followed by doublet plus cetuximab or panitumumab (21%). The cost of molecular targeted drugs-containing regimens (ranging from 85 406 to 843 602 JPY/month) is much higher than that of only cytotoxic drug regimens (ranging from 17 672 to 51 004 JPY/month). About 16% received high-cost treatments that included panitumumab-containing regimens and pembrolizumab (17% of patients aged ≤74years and 11% of patients aged ≥75years). About 16% of mCRC patients received first-line treatment with regimens costing >500 000JPY/month, and molecular targeted drugs being the main drivers of cost.

Trends and Patterns of HIV Transmitted Drug Resistance in China From 2018 to 2023.

National treatment guidelines of China evolving necessitates population-level surveillance of transmitted drug resistance (TDR) to inform or update HIV treatment strategies. We analyzed the demographic, clinical, and virologic data obtained from people with HIV (PWH) residing in 31 provinces of China who were newly diagnosed between 2018 and 2023. Evidence of TDR was defined by the World Health Organization list for surveillance of drug resistance mutations. Among the 22 124 PWH with protease and reverse transcriptase sequences, 965 (4.36%; 95% CI, 4.1-4.63) had at least 1 TDR mutation. The most frequent TDR mutations were nonnucleoside reverse transcriptase inhibitor (NNRTI) mutations (2.39%; 95% CI, 2.19%-2.59%), followed by nucleoside reverse transcriptase inhibitor mutations(1.35%; 95% CI, 1.2%-1.5%) and protease inhibitor mutations (1.12%; 95% CI, .98%-1.26%). The overall protease and reverse transcriptase TDR increased significantly from 4.05% (95% CI, 3.61%-4.52%) in 2018 to 5.39% (95% CI, 4.33%-6.57%) in 2023. A low level of integrase strand transfer inhibitor TDR was detected in 9 (0.21%; 95% CI, .1%-.38%) of 4205 PWH. Presently, the continued use of NNRTI-based first-line antiretroviral therapy regimen for HIV treatment has been justified.

Bayesian network analysis of drug treatment strategies for thyroid associated ophthalmopathy.

The first line treatment for moderate to severe active thyroid associated ophthalmopathy is glucocorticoid pulse therapy, but for patients with contraindications to hormone therapy or hormone resistance, it is urgent to find a suitable treatment plan. To find a reliable alternative to hormone pulse therapy for thyroid associated ophthalmopathy by comparing the efficacy with first-line treatment regimens. Search PubMed, Ovid, Web of science, Cochrane library, and Clinical Trials.gov for randomized controlled trials on the treatment of thyroid associated ophthalmopathy published as of July 7, 2024. Quality evaluation and Bayesian network analysis were conducted using RevMan 5.3 software, STATA15.0 software, and ADDIS 1.16.8 software. A total of 666 patients were included in 11 studies and 8 interventions. Network analysis showed that the three interventions of mycophenolate mofetil combined with glucocorticoids, Teprotumumab and 99Tc-MDP were superior to glucocorticoid pulse therapy in improving clinical activity scores and proptosis. The regimen of glucocorticoids combined with statins can improve the quality of life score and diplopia score of patients. Neither methotrexate combined with glucocorticoids nor rituximab alone showed additional advantages when compared with glucocorticoid pulse therapy. Mycophenolate mofetil combined with glucocorticoid therapy is very beneficial for moderate to severe active thyroid associated ophthalmopathy. Mycophenolate mofetil may be a good choice when patients have contraindications to hormone use or hormone resistance. Teprotumumab is very promising and may be able to avoid patients undergoing orbital decompression surgery. The durability and safety of its long-term efficacy need to be further observed.

Clinical Features and Prognosis of Secondary Intestinal Diffuse Large B-Cell Lymphoma

To explore and analyze the clinical features and prognostic factors of secondary intestinal diffuse large B-cell lymphoma (SI-DLBCL), in order to provide reference for the basic research and clinical diagnosis and treatment of secondary lymphoma of rare sites in the field of hematology. The clinical data of 138 patients with SI-DLBCL admitted to Fujian Medical University Union Hospital from June 2011 to June 2022 were collected and sorted, the clinical and pathological features, diagnosis, treatment and prognosis were analyzed. Cox regression risk model was used to conduct univariate and multivariate analysis on the prognostic risk factors. Among the 138 patients with SI-DLBCL included in this study, 85 (61.59%) were male, 53 (38.41%) were female, the median age of onset was 59.5 (16-84) years, the clinical manifestations lacked specificity, the first-line treatment regimen was mainly chemotherapy (67.39%), 94 cases (68.12%) received chemotherapy alone, 40 cases (28.98%) were treated with chemotherapy combined with surgery, and 4 cases (2.90%) were treated with surgery alone. The median follow-up time was 72 (1-148) months. Among the 138 patients with SI-DLBCL, 79 (57.25%) survived, 34 (24.64%) died, 25 cases (18.12%) lost to follow-up, the PFS rates of 1-year, 3-year and 5-year were 57.97%, 49.28% and 32.61%, and the OS rates of 1-year, 3-year and 5-year were 60.14%, 54.35% and 34.06%, respectively. The results of univariate Cox regression analysis showed that age, Lugano stage and IPI score were the influencing factors of OS in SI-DLBCL patients, and age, Lugano stage and IPI score were the influencing factors of PFS in SI-DLBCL patients. The results of multivariate Cox analysis showed that Lugano stage was an independent prognostic factor affecting OS and PFS in SI-DLBCL patients. Patients with SI-DLBCL are more common in middle-aged and elderly men, and the early clinical manifestations lack specificity, and the first-line treatment regimen is mainly R-CHOP chemotherapy, and Lugano stage is an independent prognostic factor affecting OS and PFS in SI-DLBCL patients.

Evaluation of Efficacy and Safety in First-Line Treatment Methods for Extensive-Stage Small Cell Lung Cancer: A Comprehensive Comparative Study of Chemotherapy, Targeted Therapy Combined With Chemotherapy, and Immunotherapy Combined With Chemotherapy.

Small cell lung cancer (SCLC) is a highly aggressive tumor with limited effectiveness in its standard chemotherapy treatment. Targeted antiangiogenic therapy and immune checkpoint inhibitors (ICIs) have demonstrated potential as alternative treatments for extensive-stage SCLC (ES-SCLC). However, there is insufficient comparative evidence available to determine the optimal first-line treatment option between ICIs plus chemotherapy and targeted antiangiogenic therapy plus chemotherapy. This study is aimed at analyzing clinical data from ES-SCLC patients treated at the First Affiliated Hospital of Bengbu Medical College between June 2021 and June 2023. The study compared the efficacy and safety of three first-line treatment regimens: standard chemotherapy, antiangiogenic therapy combined with chemotherapy, and immune combination therapy. Patients who met the inclusion criteria were divided into three groups: chemotherapy, immune combination therapy, and antiangiogenic therapy combined with chemotherapy. The study collected data on clinical characteristics, treatment regimens, and adverse reactions. The analysis included objective response rate (ORR), duration of response (DoR), disease control rate (DCR), progression-free survival (PFS), and treatment safety. A total of 101 patients were included in the study, with 49 receiving chemotherapy alone, 19 receiving antiangiogenic therapy, and 33 receiving immune combination therapy. The ORRs were 78.9% for antiangiogenic therapy, 72.7% for immune combination therapy, and 42.9% for chemotherapy alone. The median PFS was 8.0 months for antiangiogenic therapy, 7.8 months for immune combination therapy, and 5.2 months for chemotherapy alone. Both combination therapy groups demonstrated superior efficacy compared to chemotherapy alone. Targeted combined chemotherapy and immune combination chemotherapy showed superior efficacy as first-line treatments for ES-SCLC compared to chemotherapy alone, with manageable adverse reactions.

Navigating first-line therapies for extensive-stage small-cell lung cancer: a frequentist network meta-analysis and systematic review.

Aim: To identify the optimal first-line treatment for patients with extensive-stage small-cell lung cancer (ES-SCLC).Materials & methods: We conducted a network meta-analysis (CRD42023486863) to systematically evaluate the efficacy and safety of eight first-line treatment regimens for ES-SCLC, including 15 clinical trials.Results: Our analysis showed that the PD-1/PD-L1+ etoposide combined withplatinum (EP)and PD-L1+ vascular endothelial growth factor (VEGF) +EP regimens significantly enhanced overall survival and progression-free survival, with subgroup analysis revealing that serplulimab ranked as the most promising option for improving overall survival. Integrating anti-angiogenesis drugs into immunochemotherapy presents potential benefits, with an increased incidence of adverse events necessitating further investigation.Conclusion: Our findings offer valuable insights for future research and for developing more effective treatment strategies for ES-SCLC, underscoring the critical need for continued innovation in this therapeutic area.

Safety of first-line systemic therapy in patients with metastatic colorectal cancer: a network meta-analysis of randomized controlled trials

ObjectiveTo evaluate the safety of first-line systemic therapy for metastatic colorectal cancer through network meta-analysis.MethodsThe literature from PubMed, Embase, Web of Science, and Cochrane Library databases was searched from the inception of the databases to August 15, 2023, and strict inclusion and exclusion criteria were applied to screen studies. The Cochrane Bias Risk Assessment Tool (RoB 2.0) was used to evaluate the quality of the included literature. Network meta-analysis was conducted using Stata 15.0 and R4.3.1 software to compare the incidence of adverse events (AEs) among different treatment regimens.ResultsA total of 53 randomized controlled trials, involving 17,351 patients with metastatic colorectal cancer (mCRC), were ultimately included, encompassing 29 different therapeutic approaches. According to SUCRA rankings, the CAPOX regimen is most likely to rank first in terms of safety, while the FOLFOXIRI + panitumumab regimen is most likely to rank last. In terms of specific AEs, the CAPOX regimen, whether used alone or in combination with targeted drugs (bevacizumab and cetuximab), is associated with a reduced risk of neutropenia and febrile neutropenia, as well as an increased risk of thrombocytopenia and diarrhea. The FOLFOX regimen, with or without bevacizumab, is linked to an increased risk of neutropenia and peripheral sensory neuropathy. The FOLFIRI/CAPIRI + bevacizumab regimen is associated with a reduced risk of peripheral sensory neuropathy. S-1 and S-1 + oxaliplatin are well-tolerated in terms of gastrointestinal reactions. The FOLFOXIRI regimen, whether used alone or in combination with targeted drugs, is associated with various AEs.ConclusionIn summary, the CAPOX regimen may be the safest option among the first-line systemic treatment regimens for mCRC patients, while the FOLFOXIRI + panitumumab regimen may be associated with a higher incidence of grade 3 or higher AEs.

Feasibility of Indirect Treatment Comparisons Between Niraparib Plus Abiraterone Acetate and Other First-Line Poly ADP-Ribose Polymerase Inhibitor Treatment Regimens for Patients with BRCA1/2 Mutation-Positive Metastatic Castration-Resistant Prostate Cancer.

Poly(ADP-ribose) polymerase inhibitors (PARPi) are a novel option to treat patients with metastatic castration-resistant prostate cancer (mCRPC). Niraparib plusabiraterone acetate and prednisone (AAP) is indicated for BRCA1/2 mutation-positive mCRPC. Niraparib plus AAP demonstrated safety and efficacy in the phase 3 MAGNITUDE trial (NCT03748641). In the absence of head-to-head studies comparing PARPi regimens, the feasibility of conducting indirect treatment comparisons (ITC) to inform decisions for patients with first-line BRCA1/2 mutation-positive mCRPC has been explored. A systematic literature review was conducted to identify evidence from randomized controlled trials on relevant comparators to inform the feasibility of conducting ITCs via network meta-analysis (NMA) or population-adjusted indirect comparisons (PAIC). Feasibility was assessed based on network connectivity, data availability in the BRCA1/2 mutation-positive population, and degree of within- and between-study heterogeneity or bias. NMAs between niraparib plus AAP and other PARPi regimens (olaparib monotherapy, olaparib plus AAP, and talazoparib plus enzalutamide) were inappropriate due to the disconnected network, differences in trial populations related to effect modifiers, or imbalances within BRCA1/2 mutation-positive subgroups. The latter issue, coupled with the lack of a common comparator (except for olaparib plus AAP), also rendered anchored PAICs infeasible. Unanchored PAICs were either inappropriate due to lack of population overlap (vs. olaparib monotherapy) or were restricted by unmeasured confounders and small sample size (vs. olaparib plus AAP). PAIC versus talazoparib plus enzalutamide was not possible due to lack of published arm-level baseline characteristics and sufficient efficacy outcome data in the relevant population. The current randomized controlled trial evidence network does not permit robust comparisons between niraparib plus AAP and other PARPi regimens for patients with 1L BRCA-positive mCRPC. Decision-makers should scrutinize any ITC results in light of their limitations. Real-world evidence combined with clinical experience should inform treatment recommendations in this indication.

Advancements in First-Line Treatment of Metastatic Bladder Cancer: EV-302 and Checkmate-901 Insights and Future Directions.

Advanced bladder cancer patients have historically failed to achieve prolonged duration of response to conventional chemotherapy and needed better first-line treatment regimens. The approval of nivolumab in combination with gemcitabine and cisplatin and pembrolizumab with antibody-drug conjugate enfortumab vedotin has revolutionized the first-line treatment of advanced bladder cancer in many countries. In this review, we summarize the intricate differences between the two landmark clinical trials that led to their incorporation into the current standard of care for advanced bladder cancer. We further discuss newer novel treatment options in the second and subsequent lines of treatment on progression, like immunotherapy in combination with other agents, including fibroblast growth factors receptor inhibitors, human epidermal growth factor inhibitors, antibody-drug conjugates, tyrosine kinase inhibitors, and novel antibodies. Finally, we discuss the integration of these novel therapies into current clinical practice amidst the rapidly evolving landscape of advanced bladder cancer treatment, aiming to enhance patient outcomes.

Acquired haemophilia A in Finland: A nationwide study of incidence, treatment and outcomes.

Acquired haemophilia A (AHA) is a bleeding disorder caused by autoantibody development against factor VIII (FVIII). Studies on AHA have mainly focused on patients treated at specialist centres. To determine the incidence, clinical characteristics and outcomes of AHA in an unselected population-based patient cohort from Finland. This retrospective observational cohort comprised all cases diagnosed with AHA in Finland between 2006 and 2019. Patients were identified by the two central laboratories performing FVIII antibody testing in Finland, the Finnish Red Cross Blood Service and HUSLAB. Clinical details were collected from all hospitals and healthcare units where patients were treated. This study was performed in conjunction with the AHA in the Nordics study. The median incidence of AHA was 0.65 per million per year (range 0.19-1.27). Fifty-five patients were identified, with a median age of 76 years and an even sex ratio (51% women). When diagnosed, all had bleeding symptoms with severe bleeds in 92%. First-line immunosuppressive treatment regimens included steroid monotherapy in 31% of cases, steroids and a cytotoxic agent in 51% and a rituximab-based regimen in 16%. Clinical remission was achieved in 71% of cases, and 15% had relapses. Mortality was 13% for bleeds and 9% for treatment-related infections. Overall survival was 64% for 1 year and 56% for 2 years after diagnosis. In a nationwide population-based cohort study, we discovered a lower incidence of AHA than previously reported. Mortality among patients with AHA was high, calling for the consideration of updated treatment strategies.

Immunotherapy for endometrial cancer.

Advanced recurrent endometrial cancer (EC) has a poor prognosis and new treatment options are needed. In 2013, EC was classified by genomic analysis into four groups: the POLE ultra-mutated group, the MSI-high hypermutated group (MSI-H), the copy number low group, and the copy number high group. The prognosis differs based on the classification, which should enable the individualization of treatment. The MSI-H and POLE types can induce PD-L1 expression in cancer cells. Among the gynecological cancers, EC exhibits the highest levels of PD-1 and PD-L1 expression and has the highest proportion of MSI-H. Thus, an immune checkpoint inhibitor (ICI) is expected to be effective. The first ICI to show efficacy in recurrent EC was the anti-PD1 antibody pembrolizumab, which exhibited efficacy in MSI-H EC. The combination of pembrolizumab and the multi-kinase inhibitor lenvatinib significantly prolongs OS/PFS compared with single-agent chemotherapy in previously treated recurrent EC, regardless of MSI status. ICIs are now moving from second-line and beyond to first-line treatment regimens. The efficacy of paclitaxel plus carboplatin (TC) and ICI combinations compared with TC have been demonstrated, including an ongoing Phase III trial comparing chemotherapy with the combination of pembrolizumab and lenvatinib. Although ICIs are becoming the mainstay of EC, they cause systemic inflammatory side effects known as irAEs. The incidence of irAEs is higher for combination therapy with CT or lenvatinib compared with ICI therapy alone. Even though they are rarely fatal, irAEs should be addressed promptly.
