PURPOSE: The study aimed to discern the intent to treat with the therapeutic agents prescribed first or second line in the following eye conditions: neovascular age-related macular Degeneration (nAMD), diabetic macular edema (DME), retinal vein occlusion (RVO), and myopic maculopathy with choroidal neovascularization (MMNV). The study also aimed to distinguish the ophthalmologists' intended treatment for their patients from those that they would prescribe for themselves if they were affected by the above macular conditions...

Angiogenesis is an indispensable mechanism in cancer progression, as cancer cells need to establish blood vessels to supply oxygen and nutrients. Extracellular vesicles (EVs) derived from cancer cells act as messengers in the tumor microenvironment and induce resistance to anti-angiogenic cancer treatment. EVs can be classified into two categories: exosomes and microvesicles (MVs). Although exosomes are involved in angiogenesis, the role of MVs in angiogenesis and cancer progression remains unclear. CD133 plays a key role in MV formation and oncoprotein trafficking...

BACKGROUND: Outcomes for children with high-grade gliomas (HGG) remain poor. This multicenter phase II trial evaluated whether concurrent use of vorinostat or bevacizumab with focal radiotherapy (RT) improved 1-year event-free survival (EFS) compared to temozolomide in children with newly diagnosed HGG who received maintenance temozolomide and bevacizumab. METHODS: Patients ≥ 3 and < 22 years with localized, non-brainstem HGG were randomized to receive RT (dose 54-59...

BACKGROUND: Despite the lack of proven therapies for recurrent high-grade glioma (HGG), only 8%-11% of patients with glioblastoma participate in clinical trials, partly due to stringent eligibility criteria. Prior bevacizumab treatment is a frequent exclusion criterion, due to difficulty with response assessment and concerns for rebound edema following antiangiogenic discontinuation. There are no standardized trial eligibility rules related to prior antiangiogenic use. METHODS: We reviewed ClinicalTrials...

Hepatocellular carcinoma (HCC) is a common malignancy with a poor prognosis, particularly in patients with advanced-stage disease, elderly individuals and/or in those with poor liver function. Immune checkpoint inhibitor-containing therapies, such as atezolizumab, an anti-programmed death ligand-1 monoclonal antibody, plus bevacizumab, an anti-vascular endothelial growth factor monoclonal antibody, may be effective and safe therapeutic options for elderly patients with advanced-stage HCC. The present study reports the case of a male patient his 80s who consumed alcohol with unresectable advanced-stage HCC who received combination therapy comprising atezolizumab plus bevacizumab for 6 months...

BACKGROUND: Bevacizumab with platinum doublet therapy including paclitaxel + carboplatin improves the survival of patients with non-squamous non-small cell lung cancer. However, in a previous trial (CA031), paclitaxel + carboplatin led to Grade > 3 neutropenia in a Japanese population. Nanoparticle albumin-bound paclitaxel exhibits an improved toxicity profile. We evaluated the safety, dosage and response rate of the nanoparticle albumin-bound paclitaxel + carboplatin + bevacizumab combination in a Japanese population...

BACKGROUND: Triple-negative breast cancer (TNBC) is a life-threatening subtype of breast cancer with limited treatment options. Therefore, this network meta-analysis (NMA) aimed to evaluate and compare the effect of various neoadjuvant chemotherapy (NCT) options on the long-term survival of patients with TNBC. METHODS: PubMed, Embase, Medline, Cochrane Library, Web of Science, and major international conference databases were systematically searched for randomized controlled trials (RCTs) on the efficacy of various NCT options in patients with TNBC...

IMPORTANCE: Testing for homologous recombination deficiency is required for the optimal treatment of high-grade epithelial ovarian cancer. The search for accurate biomarkers is ongoing. OBJECTIVE: To investigate whether progression-free survival (PFS) and overall survival (OS) of patients with high-grade epithelial ovarian cancer treated with maintenance olaparib or placebo differed between patients with a tumor BRCA-like genomic profile and patients without a tumor BRCA-like profile...

Objective: This study aimed to assess the potential of PARP inhibitors to prevent cardiotoxicity. Methods: First, a re-analysis and update of a previously published study was conducted. Additional searches were conducted of the PubMed and Cochrane Central Register of Controlled Trials databases on 2 June 2023. After the selection process, the pooled odds ratio (OR) for cardiac adverse events (AEs) was calculated. Second, the FAERS database was examined for 10 frequently co-administered anticancer agents. The reporting odds ratio (ROR) was calculated based on the occurrence of cardiac AEs depending on the co-administration of PARP inhibitors...

(1) Background: The coronavirus disease 2019 (COVID-19) pandemic has proven challenging to the management of patients with cancer, particularly those receiving systemic therapy. This study aimed to evaluate the impact of COVID-19 on patients with unresectable hepatocellular carcinoma (HCC) treated with atezolizumab/bevacizumab. (2) Methods: Patients with unresectable HCC who started atezolizumab/bevacizumab treatment between June 2020 and December 2021 at a tertiary cancer center in Korea were included ( n = 241) and classified according to their COVID-19 status and severity...

BACKGROUND: Long-term anti-EGFR antibody treatment increases the risk of severe dermatologic toxicities. This single-arm, phase II trial aimed to investigate the strategy of switching from cetuximab to bevacizumab in combination with FOLFIRI based on early tumor shrinkage (ETS) in patients with RAS wild-type metastatic colorectal cancer (mCRC). METHODS: Radiologic assessment was performed to evaluate ETS, defined as ≥20% reduction in the sum of the largest diameters of target lesions 8 weeks after the introduction of FOLFIRI plus cetuximab...

Given the increasing use of bevacizumab in combinatorial drug therapy for a multitude of different cancer types, there is a need for therapeutic drug monitoring to analyze the possible correlation between drug trough concentration, and therapeutic effect and adverse reactions. An ultra-performance liquid chromatography tandem-mass spectrometry method was then developed and validated to determine bevacizumab levels in human plasma samples. Chromatographic separation was achieved on a Shimadzu InertSustainBio C18 HP column, whereas subsequent mass spectrometric analysis was performed using a Shimadzu 8050CL triple quadrupole mass spectrometer equipped with an electro-spray ionization source in the positive ion mode...
