RESUMO
PURPOSE: Oral metronomic cyclophosphamide (OMC) implicates the daily administration of low doses of chemotherapy. Its antitumor activity combined with an oral administration route and a good toxicity profile makes OMC an attractive option for heavily pretreated patients. We retrospectively evaluated OMC's clinical benefit and objective response in recurrent ovarian cancer patients. METHODS: This is a retrospective observational study involving patients treated with OMC (50 mg daily) from 2017 to 2022 at the Academic Division Gynaecology, Mauriziano Hospital, Torino, Italy. Clinical benefit assessment included CA125 response, radiological response, and reported symptomatic improvement. Toxicities were reported using Common Terminology Criteria for Adverse Events version 5.0. RESULTS: Thirty-eight patients (average age 72, range 49-88) were included. 90% had FIGO stage III/IV at diagnosis and 64% underwent ≥ 3 previous lines of chemotherapy. Before OMC, 79% had ECOG 1 or 2. 8.6% of patients had a partial response (PR), and 40% a stable disease (SD). Median duration of response was 7.4 months. After 3 months on OMC, 51% experienced symptom improvement, and 53.3% experienced Ca125 reduction or stabilization. 66.7% of patients older than 75 responded to treatment; in 40% of cases, responses lasted ≥ 6 months (p = 0.08). No G3-4 hematological toxicities occurred. Nausea and fatigue G1-G2 were reported in 5 (13%) and 13 (34%) cases, respectively. CONCLUSION: OMC is a feasible therapeutic option for recurrent ovarian cancer, providing satisfying clinical responses with a good toxicity profile, even in elderly and heavily pretreated patients with a suboptimal performance status.
RESUMO
Background: No consensus has been reached regarding the efficacy of indirect decompression through oblique lumbar interbody fusion (OLIF) in severe lumbar spinal stenosis (LSS). This study investigated the impact of preoperative magnetic resonance imaging (MRI)-based grading of central and foraminal stenosis on OLIF outcomes in LSS patients and identified risk factors for postoperative clinical dissatisfaction. Methods: We retrospectively reviewed LSS patients who underwent OLIF with a minimum 1-year follow-up. Clinical scores obtained preoperatively and at 3, 6, 12, and 24 months postoperatively were analyzed using the substantial clinical benefit (SCB) framework. The severity of central and foraminal stenosis in the initial MRI was assessed through qualitative grading systems. Results: Among the 145 patients, with a mean follow-up of 33.7 months, those with severe central stenosis showed a significantly higher proportion of patients achieving SCB in the visual analog scale for leg pain (94.5% versus 83.1%; p = 0.044) at one year postoperatively than those without. However, those with severe foraminal stenosis showed significantly higher Oswestry Disability Index (ODI) scores (p = 0.024), and lower walking ability scores in the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ) (p = 0.004) at one year postoperatively than those without. The presence of a foraminal osteophyte of the superior articular process (SAP) was a significant risk factor responsible for not achieving SCB in ODI and walking ability in JOABPEQ at one year postoperatively (odds ratio: 0.20 and 0.22, respectively). Conclusions: After OLIF, patients with severe central stenosis showed clinical outcomes comparable to those without. The improvement in ODI and walking ability in JOABPEQ was limited in patients with severe foraminal stenosis. Surgeons should consider direct decompression in cases with the presence of foraminal osteophytes of SAP.
RESUMO
BACKGROUND: Amivantamab, an EGFR-MET bispecific antibody, is the first approved targeted therapy for patients with EGFR Ex20ins NSCLC after prior platinum-based chemotherapy-a population with historically poor outcomes before amivantamab approval. As antitumor activity in single-arm studies typically focuses on responders, the evaluation of outcomes in patients with stable disease (SD) as best response is of clinical interest. PATIENTS AND METHODS: Among 114 patients with post-platinum EGFR Ex20ins NSCLC in CHRYSALIS (NCT02609776; data cutoff: March 30, 2021), response was assessed by blinded independent central review via RECIST v1.1. Patients alive and receiving therapy at 12 weeks were grouped by response at this landmark: partial or complete response (PR+), SD, or progressive disease (PD). Progression-free survival (PFS) and overall survival (OS) by response cohort were determined using the Kaplan-Meier method; hazard ratios (HRs) and 95% confidence intervals (CIs) between response cohorts were calculated using Cox proportional hazards regression. RESULTS: Among patients alive and receiving therapy at 12 weeks (n=107), 42 (39%) had PR+, 52 (49%) had SD, and 13 (12%) had PD. Among patients with PR+ and SD, median PFS was 12.2 and 7.0 months, respectively. A corresponding improvement in OS was observed in patients achieving PR+ (median: not reached; HR vs PD=0.21 [95% CI: 0.08-0.54]) and SD (median: 23.0 months; HR vs PD=0.33 [95% CI: 0.14-0.77]), relative to those with PD (median: 14.0 months). CONCLUSION: SD was observed in 49% of patients receiving amivantamab, with corresponding increases in OS that dramatically improved the prognoses of this patient population.
RESUMO
BACKGROUND: Bone and soft tissue sarcomas are rare malignancies, and their heterogeneity has limited the development of novel drugs. This study aimed to apply two validated tools to evaluate the clinical benefits of novel drug therapies for sarcoma developed over the last decade. METHODS: The PubMed and Embase databases were searched for randomized controlled trials (RCTs) of systemic therapies for sarcomas published between 2013 and 2023. Each trial was scored according to the European Society of Medical Oncology-Magnitude of Clinical Benefit Scale version 1.1 (ESMO-MCBS) and the American Society of Clinical Oncology-Value Framework version 2 (ASCO-VF). RESULTS: We included 52 RCTs in this study, of which 17 (32.7%) reported positive results that favored the experimental arm. The ESMO-MCBS grades were determined in 14/17 positive trials, and three of them (21.4%) met the threshold for meaningful clinical benefit. Likewise, ASCO-VF scores were calculated for 11/17 positive trials, and three of them (27.3%) met the threshold for meaningful clinical benefit. Weak correlation (r = 0.38, P = 0.277) and agreement (κ = 0.211, P = 0.490) were observed between the two frameworks. CONCLUSION: Only a few RCTs with positive results have demonstrated substantial patient benefits for bone and soft tissue sarcomas over the past decade.
RESUMO
INTRODUCTION: Deucravacitinib demonstrated superior efficacy to apremilast in patients with moderate to severe plaque psoriasis in the POETYK PSO-1 and PSO-2 clinical trials. In the study reported here, we aimed to determine the overall 52-week cumulative clinical benefit of treatment initiated with deucravacitinib versus apremilast and to compare the 52-week cumulative benefit of initiating and staying on deucravacitinib versus initiating apremilast and continuing or switching to deucravacitinib at week 24 of treatment. METHODS: This post hoc analysis of POETYK PSO-1 data (ClinicalTrials.gov identifier: NCT03624127) determined the cumulative clinical benefit of deucravacitinib 6 mg once daily and apremilast 30 mg twice daily in adults with moderate to severe plaque psoriasis. Patients treated with apremilast who did not achieve a 50% reduction in the Psoriasis Area and Severity Index (PASI 50) at week 24 were switched to deucravacitinib. The cumulative clinical benefit of deucravacitinib versus apremilast over 52 weeks was based on cumulative measures of ≥ 75% improvement from baseline in PASI score (PASI 75) and the proportion of patients with a static Physician Global Assessment score of 0 or 1 (sPGA 0/1). Ratios of area under the curve estimates between treatments were calculated and compared based on analysis of covariance regression models. RESULTS: Patients initiating deucravacitinib (N = 332) had a greater cumulative benefit as measured by the PASI 75 and sPGA 0/1 than those initiating apremilast (N = 168). Over 52 weeks, those initiating deucravacitinib experienced 50% more benefit as measured by PASI 75 and 58% more benefit as measured by sPGA 0/1 than those initiating apremilast. Results were consistent with the primary analysis when patients were classified by prior systemic and prior biologic therapy exposure. CONCLUSION: Results from this analysis corroborate the primary efficacy analysis supporting the use of deucravacitinib compared with apremilast for moderate to severe plaque psoriasis, regardless of prior systemic or biologic use.
RESUMO
BACKGROUND: Plain radiographs remain the standard for diagnosing osteoarthritis (OA). Total hip arthroplasty (THA) is generally offered only for advanced OA by plain radiographs. Advanced imaging is used as an adjunct to assess OA severity in cases of progressive symptoms with less advanced OA by plain radiographs. The objective of this study was to compare outcomes following THA in patients who have advanced OA visualized by plain radiographs to patients who have less severe OA visualized by plain radiographs. METHODS: From February 2016 to February 2020, 93 patients who had Kellgren-Lawrence (KL) grade 0 to 2 OA and underwent THA were identified. The median age was 65 years, and 55% were women. They were matched 1:3 to patients who underwent THA for KL 4 OA based on age, sex, body mass index, and Charlson Comorbidity Index. The primary outcome was achievement of the Hip Injury and Osteoarthritis Outcome Score for Joint Replacement (HOOS JR) minimum clinically important difference, substantial clinical benefit, and patient-acceptable symptom state at 1 year postoperatively. RESULTS: There was no difference between the KL 0 to 2 and KL 4 cohorts in the achievement of HOOS JR minimum clinically important difference (86 versus 85.6%, P = .922), substantial clinical benefit (81.7 versus 80.2%, P = .751), or patient-acceptable symptom state (89.2 versus 85.6%, P = .374). The KL 0 to 2 cohort had a similar improvement in their 2-year HOOS JR (42.5 versus 38.6, P = .019). CONCLUSIONS: In this series, there was no difference in outcomes following primary THA between patients who have severe OA on plain radiographs (KL 4) compared to those who have less severe OA (KL 0 to 2). In the setting of severe symptoms and the absence of advanced OA on radiographs, advanced imaging can be used to guide treatment and select patients who could benefit from THA.
RESUMO
Children deserve to be treated with appropriate medicines based on robust assessments. Despite the introduction of new regulations, the availability of medicines for children is suboptimal because of the frequent lack of relevant clinical trials due to the difficulty of conducting such trials. Thus, the Transparency Committee (TC) of the French National Authority for Health, who oversees the assessment of medicinal products in France, set up a pediatric working group with two aims: (1) The first aim was to review all opinions on medicines for pediatric use. Out of 536 opinions delivered between 2020 and 2022, 181 (34 %) concerned medicines for pediatric use. Whereas oncology largely dominated the medicines for adults, medicines for infectious diseases, endocrinology/metabolism, neurology, and hematology mostly prevailed for children. (2) The second aim was to clarify the evaluation criteria assessed by the TC, namely, the clinical benefit (CB), the clinical added value (CAV), and the public health impact (PHI) for pediatric medicinal products. An important CB was given to 113 out of 161 (71 %) opinions on medicines for pediatric use when it concerned pathologies with a severe prognosis. The quality of the demonstration (e.g., double-blind randomized trial vs. placebo or another active medicine) played a major role in the CB level. Clinical pediatric studies were also consistently associated with higher CAV levels: levels I (major) to III (moderate) in 26 out of 42 (62 %) opinions, level IV (minor) and level V (no therapeutic progress) in 43 out of 84 (51 %) and 30 out of 43 (70 %) opinions granting a sufficient CB, respectively. Conversely, 22 out of 30 (73 %) dossiers based only on literature reviews were given a level V. The main criteria leading to the qualification of a medicine for pediatric use as providing a PHI included a significant change in the morbidity and mortality of the disease and an improvement in the care pathway. Assessments were mostly aligned on the adults in the case of subsequent extensions of indications to children. Lastly, new measures were taken aimed at shortening median delays in the assessment process in order to reduce off-label use of medicines in France.

Introduction Abdominal angiography procedures such as transarterial chemoembolization (TACE) are essential for hepatocellular carcinoma treatment. One method commonly used is transfemoral access (TFA). However, issues associated with this method, which include postoperative compression of the puncture site and long periods of bed rest, can affect patient satisfaction. Thus, transradial access (TRA), a minimally invasive treatment method that improves treatment quality, was developed for TACE. This retrospective, multicenter study aimed to investigate the efficacy and safety of abdominal angiography using the radial artery approach. Methods In total, 1,601 patients underwent abdominal angiography using TRA and received treatment (radial access for visceral intervention (RAVI)) at 14 institutions in Japan. The treatment time, procedure completion rate, patient satisfaction, and complications were investigated. Results The success rate of RAVI was 99.4%, and the complication rate was 1.2%. Approximately 98.2% of the patients requested the radial artery approach again. There were no significant differences in the success rate of RAVI and the incidence of complications based on the operator's years of experience or the patient's age. Some patients developed minor complications such as puncture site bleeding, hematoma, vascular pain, and vasospasm. Further, serious complications (cerebral infarction (n = 1), cerebellar infarction (n = 1), and aortic dissection (n = 1)) were observed. Conclusion Similar to the conventional TFA, RAVI helped in facilitating peritoneal angiography safely. In abdominal angiography, this method can reduce patient burden and can be widely used in the future from the perspective of clinical benefit.
RESUMO
Background: Predictive biomarkers for immune checkpoint blockade in the second-line treatment of metastatic renal cell carcinoma (mRCC) are lacking. Materials and methods: Patients with histologically confirmed RCC who started nivolumab after at least 4 months of tyrosine kinase inhibitors (TKIs) were recruited for this study. Serial tissue and blood samples were collected for immune biomarker evaluation. The primary endpoint was to determine the association of specific T-cell subsets with clinical outcomes tested using Wilcoxon rank sum for clinical benefit rate (CBR) and log-rank test for progression-free survival (PFS). Results: Twenty patients were included in this trial with a median age of 64 years and followed-up for a median of 12 months. The median PFS for patients who received TKI was 13.8 months, while for those subsequently treated with nivolumab following TKI therapy, the median PFS was 2.6 months. CBR of nivolumab was 20% with two partial responses. Functionally active programmed cell death protein 1+ CD4+ T cells were enriched in non-responders (q = 0.003) and associated with worse PFS on nivolumab (P = 0.04). Responders showed a significant reduction in the effector CD4+T-cell (TEF) fraction compared to non-responders at 3 months on nivolumab (0.40 versus 0.80, P = 0.0005). CD127+CD4+ T cells were enriched in patients who developed immune-related adverse effects (q = 0.003). Using in-house validated multiplex immunohistochemistry for six markers, we measured tumour-associated immune cell densities in tissue samples. Responders to nivolumab showed a significantly higher mean of immune cell densities in tissue samples compared to non-responders (346 versus 87 cells/mm2, P = 0.04). Conclusions: In this small study, analysis of tissue-based and peripheral blood immune cell subsets predicted clinical outcomes of nivolumab. Further studies are warranted with larger populations to validate these observations.
RESUMO
INTRODUCTION: The study evaluates the first-line application of pembrolizumab in metastatic non-small-cell lung cancer (mNSCLC), head and neck squamous cell cancer (HNSCC), gastric cancer, and renal cell carcinoma. Utilizing the European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS) and the American Society of Clinical Oncology Value Framework (ASCO-VF), the analysis incorporates data from pivotal KEYNOTE trials. METHODS: The study systematically assessed the clinical benefit of pembrolizumab in advanced solid malignancies through nine randomized controlled trials, one of which comprised two experimental arms. Data extraction from primary sources was conducted from PubMed, ASCO, and ESMO publications. Utilizing ESMO-MCBS and ASCO-VF forms, the evaluation focused on clinical benefit, toxicity, and bonus points, with discrepancies resolved through consensus discussions. RESULTS: Nine first-line indications for pembrolizumab received Food and Drug Administration approval for metastatic solid tumors between 2018 and 2023. Notable distinctions in ESMO-MCBS grades revealed seven trials with substantial clinical benefit (grades 5 to 4) and three with moderate to negligible benefit (grades 3 to 1). Bonus points, primarily based on the tail of the curve, were allocated to three trials for overall survival, one for progression-free survival, and one for a significant improvement in quality of life. CONCLUSIONS: Our evaluation of pembrolizumab across diverse cancers, especially in mNSCLC and HNSCC, revealed varied outcomes and challenges in clinical benefit interpretation. The assessment of clinical benefit, incorporating quantitative and qualitative endpoints, underscores the need to consider survivorship outcomes and patient perspectives for a comprehensive understanding.
RESUMO
Head and neck squamous cell carcinomas (HNSCC) have proven to be inherently resistant to systemic treatments as a result of histological, molecular, and etiological heterogeneity, with limited responses seen after second-line therapy and beyond. With limited treatment options after progression on systemic chemotherapy in HNSCCs, immunotherapy has a role to play with improved results. In this prospective, observational, non-randomized, open-label study, a total of 12 patients with advanced, relapsed, or metastatic HNSCC received Inj. Nivolumab weight-based dose of 3 mg per kg, intravenously every 2 weeks along with low-dose capecitabine 500 mg twice a day, was prospectively assessed. The patient's clinical, hematological, and staging characteristics were described and the clinical benefit rate (CBR) was calculated. A total of 12 patients received the combined metronomic chemo-immunotherapy (CMCI). The majority of patients were belonging to ECOG-PS 1(66%), with all patients being in stage IV disease. Six, four, and two patients received immunotherapy as the 5th, 3rd, and 4th line of therapy, respectively. Nivolumab and low-dose capecitabine were used in all 12 patients. CBR was seen in 66% (8/12) of patients, one patient died due to hepatitis and hepatic encephalopathy, another patient died due to pneumonia and respiratory complications, two patients had progressive disease, and two patients with stable disease discontinued treatment because of financial constraints and kept on capecitabine alone. The majority tolerated therapy well with no grade 3/4 immune-related adverse events (IRAEs). Two patients required supportive therapy with packed red cell transfusion and albumin infusions. Six-month overall survival (OS) and progression-free survival (PFS) in the study population were 83.3% and 66.6%, respectively. In conclusion, nivolumab along with metronomic chemotherapy with low-dose capecitabine was very well tolerated and exhibited anti-tumor activity with a CBR of 66%, 6-month OS of 83.3%, and 6-month PFS of 66.6%, in extensively pretreated patients with HNSCCs. Additional studies of nivolumab and metronomic chemotherapy and immuno-immuno combination therapy in these diseases are ongoing.
RESUMO
Background: In the COMPASS trial, the combination of acetylsalicylic acid (ASA) plus 2.5 mg rivaroxaban twice daily (dual-pathway inhibition, DPI) has been shown to be superior to ASA monotherapy for the reduction in ischemic major adverse cardiovascular events (MACEs, i.e., cardiovascular death, stroke, or myocardial infarction). Methods: The international XATOA registry (Xarelto plus Acetylsalicylic acid: Treatment patterns and Outcomes in patients with Atherosclerosis) is a prospective post-approval registry that investigates the cardiovascular outcomes of patients taking ASA plus 2.5 mg rivaroxaban. The aim of this pre-specified analysis was to determine the net clinical outcome (NCO), i.e., a combination of MACEs and bleeding events, of DPI in patients from daily clinical practice. Results: Among the 5615 patients, the presence of multiple risk factors resulted in an increase in the total risk of experiencing an NCO event, e.g., from 1.27% (one risk factor) to 2.18% (two risk factors) and 4.07% (three or more risk factors), respectively, with ischemic MACE representing the primary driver of bleeding complications. Conclusions: In the real-world XATOA registry, the annual rate of NCO events was low and numerically similar to those seen in the treatment group in the randomized COMPASS trial.
RESUMO
OBJECTIVE: The purpose of this study was to investigate the efficacy and safety of lenvatinib in various types of solid tumors. METHOD: By searching PubMed, Web of Science, Cochrane, CNKI, Wanfang and other databases, all the literatures about the comparison of clinical efficacy of lenvatinib in the treatment of various solid tumors. According to the criteria of inclusion and exclusion of literature, two participants screened the literature, collated the data and evaluated the literature. RevMan 5.4 software was used for meta-analysis of the included literatures. RESULTS: A total of 12 studies were included, including 5213 patients. Meta-analysis showed that, in terms of efficacy, the risk (HR) of prolonging PFS in the treatment of various solid tumors in the lenvatinib group was 1.91 times that in the control group (HR = 1.91, 95% CI: 1.58-2.31, p < 0.00001), and the risk (HR) of prolonging OS was 1.27 times that in the single targeted drug group (HR = 1.27, 95% CI: 1.15-1.40, p < 0.00001). In terms of safety, the risk of adverse events in the treatment of various solid tumors in the lenvatinib group was higher than that in the control group, especially in Endocrine Toxicities, Renal/Urinary Toxicities, Vascular Toxicities, Musculoskeletal/a Connective Tissue Toxicities and Metabolism/Nutrition Toxicities. CONCLUSIONS: Lenvatinib in various solid tumors can prolong OS and disease PFS of patients, improve the clinical benefit rate and improve the quality of life of patients. At the same time, there is a certain incidence of adverse events, and symptomatic intervention should be given in clinical medication.

PURPOSE: This study aims to estimate changes in the value of oncology drugs over time from initial data of the reimbursement decisions to subsequent publications in Korea, using two value frameworks. METHODS: We retrieved primary publications assessed for reimbursement between 2007 and July 2021 from the decision documents of Health Insurance Review and Assessment and subsequent publications made available following reimbursement decision from ClinicalTrials.Gov and PubMed databases. Changes in the clinical benefit scores were assessed using the American Society of Clinical Oncology Value Framework (ASCO-VF) and the European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS). A paired t test was performed to test whether there was a difference in the scores between primary and subsequent publications. RESULTS: Of 73 anticancer product/indication pairs, 45 (61.6%) had subsequent publications, of which 62.5% were released within 1 year of reimbursement decision. The mean ESMO-MCBS and ASCO-VF Net Health Benefit scores increased from primary to subsequent publications, although the differences were not significant. The mean ASCO-VF bonus score significantly increased from 15.91 to 19.09 (p = 0.05). The ESMO-MCBS and bonus scores increased by 0.25 and 0.21, respectively, and the bonus score had a greater impact on the ESMO-MCBS score than the preliminary score did. CONCLUSION: The value of drugs demonstrated in subsequent publications varies considerably among oncology drugs, depending on uncertainty associated with the initial evidence and the availability of updated evidence. As decision-making in the face of uncertainty becomes more prevalent, the value frameworks can serve as simple screening tools for re-evaluation in these cases.

OBJECTIVE: To compare substantial clinical benefit (SCB) of a hydrogel-based, matrix-associated autologous chondrocyte implantation (M-ACI) method versus microfracture (MFx) in the treatment of knee cartilage defects. DESIGN: Propensity score matched-pair analysis, using the MFx control group of a phase III study as comparator for M-ACI treatment in a single-arm phase III study, resulting in 144 patients in the matched-pair set. RESULTS: Groups were comparable regarding baseline Knee Injury and Osteoarthritis Outcome Score (KOOS), sex, age, body mass index, symptom duration, smoking status, and previous knee surgeries. Defect sizes in the M-ACI group were significantly larger than in the MFx group (6.4 cm2 vs. 3.7 cm2). Other differences concerned location, number, and etiology of defects that were not considered to influence the interpretation of results. At 24 months, significantly more patients in the M-ACI group achieved SCB in KOOS pain (72.2% vs. 48.6%; P = 0.0108), symptoms (84.7% vs. 61.1%, P = 0.0039), sports/recreation (84.7% vs. 56.9%, P = 0.0008), and quality of life (QoL; 72.2% vs. 44.4%, P = 0.0014). The SCBs for KOOS activities in daily living and International Knee Documentation Committee score were higher for M-ACI but not significantly different from MFx. The SCB rates consistently favored M-ACI from 3 months onward. The highest improvements from baseline at 24 months in patients with SCB were observed for KOOS sports/rec. (M-ACI: 60.8 points, MFx: 55.9 points) and QoL (M-ACI: 58.1, MFx: 57.4). CONCLUSION: Hydrogel-based M-ACI demonstrated superior SCB in KOOS pain, symptoms, sports/rec., and QoL compared with MFx in patients with knee cartilage defects through 2 years follow-up.
RESUMO
Paclitaxel, one of the most frequently used anticancer drugs, is dosed by body surface area, which leads to substantial inter-individual variability in systemic drug exposure. We evaluated clinical evidence regarding the scientific rationale and clinical benefit of individualized paclitaxel dosing based on measured systemic concentrations, known as therapeutic drug monitoring (TDM). In retrospective studies, higher systemic exposure is associated with greater toxicity and efficacy of paclitaxel treatment across several disease types and dosing regimens. In prospective trials, TDM reduces variability in systemic exposure, and has been demonstrated to reduce toxicity while retaining treatment efficacy for 3-weekly dosing in patients with advanced non-small cell lung cancer. Despite the demonstrated benefits of paclitaxel TDM, clinical adoption has been limited due to the challenges with sample collection and analysis. Based on our review, we strongly recommend TDM for patients receiving every 3-week paclitaxel in combination with a platinum agent for advanced NSCLC, due to the prospectively demonstrated clinical benefits, and find moderate evidence to recommend TDM for paclitaxel 3-hour infusions for other tumor types and preliminary evidence suggesting potential usefulness for paclitaxel administered by 1-hour infusions.

BACKGROUND: In post-stroke atrial fibrillation (AF) patients who have indications for both oral anticoagulant (OAC) and antiplatelet agent (AP), e.g., those with carotid artery stenosis, there is debate over the best antithrombotic strategy. We aimed to compare the risks of ischemic stroke, composite of ischemic stroke/major bleeding and composite of ischemic stroke/intracranial hemorrhage (ICH) between different antithrombotic strategies. METHODS: This study included post-stroke AF patients with and without extracranial artery stenosis (ECAS) (n = 6390 and 28,093, respectively) identified from the Taiwan National Health Insurance Research Database. Risks of clinical outcomes and net clinical benefit (NCB) with different antithrombotic strategies were compared to AP alone. RESULTS: The risk of recurrent ischemic stroke was higher for patients with ECAS than those without (12.72%/yr versus 10.60/yr; adjusted hazard ratio [aHR] 1.104, 95% confidence interval [CI] 1.052-1.158, p < 0.001). For patients with ECAS, when compared to AP only, non-vitamin K antagonist oral anticoagulant (NOAC) monotherapy was associated with lower risks for ischaemic stroke (aHR 0.551, 95% CI 0.454-0.669), the composite of ischaemic stroke/major bleeding (aHR 0.626, 95% CI 0.529-0.741) and the composite of ischaemic stroke/ICH (aHR 0.577, 95% CI 0.478-0.697), with non-significant difference for major bleeding and ICH. When compared to AP only, warfarin monotherapy was associated with higher risks of major bleeding (aHR 1.521, 95% CI 1.231-1.880), ICH (aHR 2.045, 95% CI 1.329-3.148), and the composite of ischaemic stroke and major bleeding. With combination of AP plus warfarin, there was an increase in ischaemic stroke, major bleeding, and the composite outcomes, when compared to AP only. NOAC monotherapy was the only approach associated with a positive NCB, while all other options (warfarin, combination of AP-OAC) were associated with negative NCB. CONCLUSIONS: For post-stroke AF patients with ECAS, NOAC monotherapy was associated with lower risks of adverse outcomes and a positive NCB. Combination of AP with NOAC or warfarin did not offer any benefit, but more bleeding especially with AP-warfarin combination therapy.

BACKGROUND: In the Netherlands, the clinical benefit of systemic anti-cancer treatments (SACTs) is assessed by the Committee for the Evaluation of Oncological Agents (cieBOM). For non-curative SACTs, the assessment is based on the hazard ratio (HR) for progression-free survival and/or overall survival (OS), and the difference in median survival. We evaluated the impact of different thresholds for effectiveness by reassessing the clinical benefit of SACTs. METHODS: We reassessed SACTs that were initially assessed by cieBOM between 2015 and 2017. Four scenarios were formulated: replacing an "OR" approach (initial assessment) by an "AND" approach (used in all scenarios), changing the HR threshold from < 0.70 (initial assessment) to < 0.60, changing the threshold for the difference in median survival from > 12 weeks (initial assessment) to > 16 weeks, and including thresholds for OS rates. The outcomes of these scenarios were compared to the outcomes of the initial assessment. RESULTS: Reassessments were conducted for 41 treatments. Replacing the "OR" approach by an "AND" approach substantially decreased the number of positive assessments (from 33 to 22), predominantly affecting immunotherapies. This number further decreased (to 21 and 19, respectively) in case more restrictive thresholds for the HR and difference in median survival were used. Including thresholds for OS rates slightly mitigated the impact of applying an "AND" approach. CONCLUSIONS: The scenario-specific thresholds had a substantial impact; the number of negative assessments more than doubled. Since this was not limited to treatments with marginal survival benefits, understanding the potential challenges that may arise from applying more restrictive thresholds is essential.

Background: Recent clinical trials demonstrated longer survival in extended small cell lung cancer (SCLC) patients treated with immunotherapy in addition to chemotherapy. However, the magnitude of benefit is modest and the impact in real-world setting has to be fully established. Methods: We collected clinical data and radiological imaging of patients affected by extended or relapsing SCLC and consecutively treated according to clinical practice between 2016 and 2023. As primary end-point, we compared pre-defined outcome indicators before and after the introduction of chemo-immunotherapy (May 2020): 6-month and 12-month progression free survival (PFS) rate, 12-month and 18-month overall survival (OS). Among those who were treated after May 2020, patients who did not receive immunotherapy according to treating physician's choice were included in the analysis to minimize clinical selection bias. Results: The analysis included 214 patients: 132 (61.7%) were treated in an Academic cancer center and 82 (38.3%) in two community hospitals; 104 were treated before May 2020. Median PFS of the overall study population was 4.8 months (95% confidence interval [95% CI]: 4.4-5.4), median OS was 7.1 months (95% CI: 6.3-7.7). Estimated PFS and OS were significantly longer in patients treated after May 2020 with hazard ratio (HR) for PFS and OS of 0.61 (95% CI: 0.46-0.81, p < 0.001) and 0.70 (95% CI: 0.52-0.93, p = 0.015), respectively. 6-month PFS rate increased from 27% to 40% (p = 0.04) while 12-months PFS raised from 1% to 11% (p = 0.003). 12-month and 18-month OS rate increased from 15% to 28% (p = 0.03) and from 2.1% to 12% (p = 0.009), respectively. After May 2020 the median number of hospitalization days per patient decreased significantly and the incidence of severe AEs was similar. Among patients treated with chemo-immunotherapy, the onset of immune-related AEs was associated with improved PFS and OS (HR 0.55, 95% CI: 0.35-0.89, p = 0.012 and HR 0.47, 95%CI 0.28-0.77, p = 0.002, respectively). Conclusions: The real-world analysis shows a meaningful improvement of outcome indicators after the introduction of chemo-immunotherapy, with reduction of the duration of hospitalization, thus supporting the use of chemo-immunotherapy and the need for further biomarker research.

BACKGROUND: In France, the potential benefit of new treatments is initially evaluated by the Haute Autorité de Santé to determine reimbursement and pricing, but rarely afterwards. Although immunotherapies (ITs) have considerably improved the survival of patients, few data are available on their long-term benefit at a population-treated level. The present retrospective study aimed to assess the clinical benefit of ITs compared to the previous standards of care (SoCs) in France from 2014 to 2021. MATERIALS AND METHODS: To do this, we analyzed all ITs from the anti-programmed cell death protein 1/programmed death-ligand 1 [anti-PD-(L)1] class used in monotherapy or in association with another treatment available in early access or reimbursed in France between 2014 and 2021, regardless of indication. The number of patients initiating an IT was retrieved by year, drug and indication. Using extrapolated Kaplan-Meier curves, utility scores and the population treated, the clinical benefit was expressed as the number of deaths prevented (DP), life-years (LYs) and quality-adjusted life years (QALYs) gained compared to previous SoC. RESULTS: Across the period, five ITs were marketed in 21 indications related to eight primary tumor sites. Between 2014 and 2021, 132 924 patients initiated an IT. By December 2021, 16 173 (13 804-17 141) deaths were delayed compared to previous SoC, mainly in lung cancer. Compared to their SoC, ITs provided a gain of 37 316 (33 581-41 048) additional LYs and 27 709 (23 784-30 450) additional QALYs. Lung cancer was the driver indication with 70.6% of LYs and 68.4% of QALYs gained followed by melanoma with 18.7% and 20.4% of the gain, respectively. CONCLUSIONS: Significant gains in DP, LYs and QALYs have been observed in France following the introduction of ITs.
