Treatment-free Survival After First-line Therapies for Metastatic Renal Cell Carcinoma: An International Metastatic Renal Cell Carcinoma Database Consortium Analysis.

Background And Objective: Patients receiving immune checkpoint blockade (ICB) therapy may experience periods of prolonged disease control without a need for systemic therapy. Treatment-free survival (TFS) is an important measure for this period, but no data are available for patients with metastatic renal cell carcinoma (mRCC) starting first-line agents. Our aim was to analyze TFS outcomes for patients with mRCC starting first-line therapy.

Is HER2 the New NECTIN4 in Advanced Urothelial Cancer?

Antibody-drug conjugates have transformed treatment for urothelial cancer (UC). Enfortumab vedotin is the new standard of care in the first-line setting for advanced UC. A personalised approach targeting HER2 in UC is currently being explored.

Upper Tract Urothelial Carcinoma (UTUC): Prevalence, Impact and Management Challenge.

Upper tract urothelial carcinoma (UTUC) is an aggressive and difficult malignancy to treat. Owing to its rarity and the lack of specific high-level data, management mirrors that of urothelial cancer of the bladder (UCB). Over the past decade, UTUC has shown minimal improvement in survival rates.

Layered rare-earth hydroxides as multi-modal medical imaging probes: particle size optimisation and compositional exploration.

Recently, layered rare-earth hydroxides (LRHs) have received growing attention in the field of theranostics. We have previously reported the hydrothermal synthesis of layered terbium hydroxide (LTbH), which exhibited high biocompatibility, reversible uptake of a range of model drugs, and release-sensitive phosphorescence. Despite these favourable properties, LTbH particles produced by the reported method suffered from poor size-uniformity (670 ± 564 nm), and are thus not suitable for therapeutic applications.

Impact of smoking status on clinical outcomes in patients with metastatic renal cell carcinoma treated with first-line immune checkpoint inhibitor-based regimens.

Background: Current tobacco smoking is independently associated with decreased overall survival (OS) among patients with metastatic renal cell carcinoma (mRCC) treated with targeted monotherapy (VEGF-TKI). Herein, we assess the influence of smoking status on the outcomes of patients with mRCC treated with the current first-line standard of care of immune checkpoint inhibitor (ICI)-based regimens.

Materials And Methods: Real-world data from the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) were collected retrospectively.

Outcomes of patients with advanced epithelial growth factor receptor mutant lung cancer treated with first-line osimertinib who would not have met the eligibility criteria for the FLAURA clinical trial.

Objectives: Osimertinib is largely used as first-line therapy for metastatic epithelial growth factor receptor (EGFR) mutant lung cancers based on the FLAURA clinical trial. Real-world patient outcomes often differ from clinical trial outcomes. This study evaluated the efficacy of first-line osimertinib in patients treated in British Columbia (BC), Canada.

Outcomes of Patients with Brain Metastases from Renal Cell Carcinoma Receiving First-line Therapies: Results from the International Metastatic Renal Cell Carcinoma Database Consortium.

Patients with brain metastases (BrM) from renal cell carcinoma and their outcomes are not well characterized owing to frequent exclusion of this population from clinical trials. We analyzed data for patients with or without BrM using the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC). A total of 389/4799 patients (8.

Magnetically driven preparation of 1-D nano-necklaces capable of MRI relaxation enhancement.

We report a novel magnetically-facilitated approach to produce 1-D 'nano-necklace' arrays composed of 0-D magnetic nanoparticles, which are assembled and coated with an oxide layer to produce semi-flexible core@shell type structures. These 'nano-necklaces' demonstrate good MRI relaxation properties despite their coating and permanent alignment, with low field enhancement due to structural and magnetocrystalline anisotropy.

Outcomes for International Metastatic Renal Cell Carcinoma Database Consortium Prognostic Groups in Contemporary First-line Combination Therapies for Metastatic Renal Cell Carcinoma.

Background: The combination of immuno-oncology (IO) agents ipilimumab and nivolumab (IPI-NIVO) and vascular endothelial growth factor targeted therapies (VEGF-TT) combined with IO (IO-VEGF) are current standard of care first-line treatments for metastatic renal cell carcinoma (mRCC).

Objective: To establish real-world clinical benchmarks for IO combination therapies based on the International mRCC Database Consortium (IMDC) criteria.

Design, Setting, And Participants: Patients with mRCC who received first-line IPI-NIVO, IO-VEGF, or VEGF-TT from 2002 to 2021 were identified using the IMDC database and stratified according to IMDC risk groups.

Background: The role of upfront cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC) in the era of immune checkpoint inhibitors is unclear.

Objective: To evaluate the relationship between upfront CN and clinical outcomes in the setting of mRCC treated with immune checkpoint inhibitors or targeted therapy.

Design, Setting, And Participants: Using the International Metastatic RCC Database Consortium, we retrospectively identified patients diagnosed with de novo mRCC treated with immune checkpoint inhibitors or targeted therapy.

CABOSEQ: The Effectiveness of Cabozantinib in Patients With Treatment Refractory Advanced Renal Cell Carcinoma: Results From the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC).

Background: There are limited data evaluating the activity of cabozantinib (CABO) as second line (2L) therapy post standard of care ipilimumab-nivolumab (IPI-NIVO) or immuno-oncology(IO)/vascular endothelial growth factor inhibitor (VEGFi) combinations (IOVE).

Materials And Methods: Using the IMDC database, we sought to identify the objective response rate, time to treatment failure (TTF) and overall survival (OS) of 2L CABO after IPI-NIVO, IOVE combinations, pazopanib or sunitinib (PAZ/SUN) or other first line (1L) therapies. Multivariable Cox regression, adjusted for underlying differences in IMDC groups, was used to compare differences in OS for 2L CABO based on preceding therapy.

Imaging Response to Contemporary Immuno-oncology Combination Therapies in Patients With Metastatic Renal Cell Carcinoma.

Importance: The association between treatment with first-line immuno-oncology (IO) combination therapies and physician-assessed objective imaging response among patients with metastatic renal cell carcinoma (mRCC) remains uncharacterized.

Objective: To compare the likelihood of objective imaging response (ie, complete or partial response) to first-line IO combination ipilimumab-nivolumab (IOIO) therapy vs approved IO with vascular endothelial growth factor inhibitor (IOVE) combination therapies among patients with mRCC.

Design, Setting, And Participants: This multicenter international cohort study was nested in routine clinical practice.

Thermo-responsive nano-in-micro particles for MRI-guided chemotherapy.

In this work, we develop nano-in-micro thermo-responsive microspheres as theranostic systems for anti-cancer hyperthermia. Firstly, layered double hydroxide (LDH) nanoparticles were synthesized and subsequently loaded with the chemotherapeutic agents methotrexate (MTX) or 5-fluorouracil (5FU). The drug-loaded LDH particles were then co-encapsulated with superparamagnetic iron oxide nanoparticles (SPIONs) into poly(acrylamide-co-acrylonitrile) microparticles via spray drying.

Randomized Controlled Trials in Lung, Gastrointestinal, and Breast Cancers: An Overview of Global Research Activity.

Background: In this study, we compared and contrasted design characteristics, results, and publications of randomized controlled trials (RCTs) in gastrointestinal (GI), lung, and breast cancer. Methods: A PUBMED search identified phase III RCTs of anticancer therapy in GI, lung, and breast cancer published globally during the period 2014−2017. Descriptive statistics, chi-square tests, and the Kruskal−Wallis test were used to compare RCT design, results, and output across the cancer sites.

Complementary Medicine Use Amongst Patients with Metastatic Cancer Enrolled in Phase III Clinical Trials.

Background: Complementary medicines (CM) are frequently used by patients with cancer. Controversy exists over the effectiveness and risk that CM may add to conventional cancer therapy. The incidence of CM use among patients enrolled in phase III clinical trials is unknown.

The effect of formulation morphology on stimuli-triggered co-delivery of chemotherapeutic and MRI contrast agents.

Most conventional chemotherapeutics have narrow therapeutic windows, and thus their delivery remains challenging and often raises safety and efficacy concerns. Theranostic platforms, with simultaneous encapsulation of therapeutic and diagnostic agents, have been proposed as next-generation formulations which can overcome this issue. In this work, we used electrohydrodynamic approaches to fabricate core@shell formulations comprising a pH responsive Eudragit L100 shell embedded with superparamagnetic iron oxide nanoparticles (SPIONs), and a thermo-responsive poly(N-isopropylacrylamide) (PNIPAM)/ethyl cellulose core loaded with the model drug carmofur.

Interactive Data Visualization Tool for Patient-Centered Decision Making in Kidney Cancer.

Purpose: Patients and providers often lack clinical decision tools to enable effective shared decision making. This is especially true in the rapidly changing therapeutic landscape of metastatic kidney cancer. Using the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) criteria, a validated risk prediction tool for patients with metastatic renal cell carcinoma, we created and user-tested a novel interactive visualization for clinical use.

Outcomes of patients with solid tumour malignancies treated with first-line immuno-oncology agents who do not meet eligibility criteria for clinical trials.

Background: Immuno-oncology (IO)-based therapies have been approved based on randomised clinical trials, yet a significant proportion of real-world patients are not represented in these trials. We sought to compare the outcomes of trial-ineligible vs. -eligible patients with advanced solid tumours treated with first-line (1L) IO therapy.

Cancer, Clinical Trials, and Canada: Our Contribution to Worldwide Randomized Controlled Trials.

Canada has a long tradition of leading practice-changing clinical trials in oncology. Here, we describe methodology, results, and interpretation of oncology RCTs with Canadian involvement compared to RCTs from other high-income countries (HICs). A literature search identified all RCTs evaluating anti-cancer therapies published 2014-2017.
