Introduction: KEYNOTE-361 evaluated first-line pembrolizumab with and without platinum-based chemotherapy versus chemotherapy alone in advanced or metastatic urothelial carcinoma. The primary end points of progression-free survival (PFS) or overall survival (OS) were not met. Exploratory analysis of efficacy by platinum agent (cisplatin or carboplatin) is reported.

Clinical variables associated with immune checkpoint inhibitor outcomes in patients with metastatic urothelial carcinoma: a multicentre retrospective cohort study.

Objectives: Immune checkpoint inhibitors (ICIs) are indicated for metastatic urothelial cancer (mUC), but predictive and prognostic factors are lacking. We investigated clinical variables associated with ICI outcomes.

Methods: We performed a multicentre retrospective cohort study of 135 patients who received ICI for mUC, 2016-2021, at three Canadian centres.

Enhancing Nutrition Support for Esophageal Cancer Patients: Understanding Factors Influencing Feeding Tube Utilization.

We sought to identify factors that can predict esophageal cancer (EC) patients at high risk of requiring feeding tube insertion. A retrospective cohort review was conducted, including all patients diagnosed with EC at our cancer center from 2013 to 2018. Multivariate logistic regression was performed comparing the group that required a reactive feeding tube insertion to those who did not require any feeding tube insertion to identify risk factors.

Amivantamab plus Chemotherapy in NSCLC with Exon 20 Insertions.

Background: Amivantamab has been approved for the treatment of patients with advanced non-small-cell lung cancer (NSCLC) with epidermal growth factor receptor () exon 20 insertions who have had disease progression during or after platinum-based chemotherapy. Phase 1 data showed the safety and antitumor activity of amivantamab plus carboplatin-pemetrexed (chemotherapy). Additional data on this combination therapy are needed.

Phase I Dose-Escalation Study of the Safety and Pharmacokinetics of AGS15E Monotherapy in Patients with Metastatic Urothelial Carcinoma.

Purpose: Effective treatment of locally advanced or metastatic urothelial carcinoma (mUC) remains an unmet need.

AGS15E is an investigational ADC that delivers the cytotoxic drug monomethyl auristatin E to cells expressing SLITRK6, a UC-associated antigen.

Programmed Cell Death Protein 1 Inhibitors and MET Targeted Therapies in NSCLC With Exon 14 Skipping Mutations: Efficacy and Toxicity as Sequential Therapies.

Introduction: NSCLC with exon 14 skipping mutation (ex14) is associated with poor outcomes. Integration of novel targeted therapies is challenging because of barriers in testing and drug access. We, therefore, sought to characterize the treatment patterns, outcomes, and emerging issues of treatment sequencing in patients with ex14-mutant NSCLC.

EGFR Targeting TKI-Related Skin Toxicities in a Patient with Darker Skin: A Case Report.

Epidermal growth factor receptor (EGFR) targeting tyrosine kinase inhibitors (TKIs) can result in significant skin toxicities that may impact patients' quality of life. While these skin reactions are well documented in patients with lighter skin, there is a paucity of literature and images to guide clinicians in their assessment in patients with darker skin tones. Given that dermatological reactions in patients with darker skin are not well represented, this can result in the undertreatment or mistreatment of these otherwise common toxicities.

Safety Related to the Timing of Radiotherapy and Immune Checkpoint Inhibitors in Patients with Advanced Non-Small Cell Lung Cancer: A Single Institutional Experience.

Background: The safety impact of radiotherapy (RT) timing relative to immune checkpoint inhibitors (ICIs) for advanced non-small-cell lung cancer (NSCLC) is unclear. We investigated if RT within 14 days (Interval 1) and 90 days (Interval 2) of ICI use is associated with toxicities compared to RT outside these intervals.

Methods: Advanced NSCLC patients treated with both RT and ICIs were reviewed.

Pembrolizumab alone or combined with chemotherapy versus chemotherapy as first-line therapy for advanced urothelial carcinoma (KEYNOTE-361): a randomised, open-label, phase 3 trial.

Background: PD-1 and PD-L1 inhibitors are active in metastatic urothelial carcinoma, but positive randomised data supporting their use as a first-line treatment are lacking. In this study we assessed outcomes with first-line pembrolizumab alone or combined with chemotherapy versus chemotherapy for patients with previously untreated advanced urothelial carcinoma.

Methods: KEYNOTE-361 is a randomised, open-label, phase 3 trial of patients aged at least 18 years, with untreated, locally advanced, unresectable, or metastatic urothelial carcinoma, with an Eastern Cooperative Oncology Group performance status of up to 2.

Updated Analysis From KEYNOTE-189: Pembrolizumab or Placebo Plus Pemetrexed and Platinum for Previously Untreated Metastatic Nonsquamous Non-Small-Cell Lung Cancer.

Purpose: In KEYNOTE-189, first-line pembrolizumab plus pemetrexed-platinum significantly improved overall survival (OS) and progression-free survival (PFS) compared with placebo plus pemetrexed-platinum in patients with metastatic nonsquamous non‒small-cell lung cancer (NSCLC), irrespective of tumor programmed death-ligand 1 (PD-L1) expression. We report an updated analysis from KEYNOTE-189 (ClinicalTrials.gov: NCT02578680).

Patient-reported outcomes following pembrolizumab or placebo plus pemetrexed and platinum in patients with previously untreated, metastatic, non-squamous non-small-cell lung cancer (KEYNOTE-189): a multicentre, double-blind, randomised, placebo-controlled, phase 3 trial.

Background: Pembrolizumab plus pemetrexed-platinum led to superior overall survival and progression-free survival, and a higher proportion of patients with a confirmed complete or partial response over placebo plus pemetrexed-platinum in the KEYNOTE-189 study. We aimed to evaluate prespecified exploratory patient-reported outcomes (PROs) in patients in KEYNOTE-189.

Methods: In the multicentre, double-blind, randomised, placebo-controlled, phase 3 KEYNOTE-189 study done at 126 cancer centres in 16 countries, eligible patients aged 18 years or older with histologically or cytologically confirmed metastatic non-squamous non-small-cell lung cancer without sensitising EGFR or ALK alterations, measurable disease as per Response Evaluation Criteria in Solid Tumors (version 1.

Multisite stereotactic body radiotherapy for metastatic non-small-cell lung cancer: Delaying the need to start or change systemic therapy?

Objectives: The purpose of this study was to review the clinical outcomes following the use of stereotactic body radiotherapy (SBRT) in patients with metastatic non-small-cell lung cancer (NSCLC) from a large academic institution.

Materials And Methods: Metastatic NSCLC patients treated with extracranial SBRT were identified from an institutional database. Treatment indications were: (1) oligometastases, (2) oligoprogression, and (3) local control of dominant tumors.

Multi-disciplinary proactive follow-up algorithm for patients with advanced NSCLC receiving afatinib.

Purpose: Afatinib is a standard first-line therapy for advanced EGFR-positive NSCLC. We implemented a pharmacist-led proactive follow-up algorithm to identify and manage early afatinib-related adverse events (AEs).

Methods: We conducted a retrospective chart review of all patients treated with afatinib after implementation of the algorithm at the Sunnybrook Odette Cancer Centre (Toronto, ON, Canada) from April 1, 2015 to July 31, 2016.

Pembrolizumab plus Chemotherapy in Metastatic Non-Small-Cell Lung Cancer.

Background: First-line therapy for advanced non-small-cell lung cancer (NSCLC) that lacks targetable mutations is platinum-based chemotherapy. Among patients with a tumor proportion score for programmed death ligand 1 (PD-L1) of 50% or greater, pembrolizumab has replaced cytotoxic chemotherapy as the first-line treatment of choice. The addition of pembrolizumab to chemotherapy resulted in significantly higher rates of response and longer progression-free survival than chemotherapy alone in a phase 2 trial.

Impact of Reflex EGFR/ ALK Testing on Time to Treatment of Patients With Advanced Nonsquamous Non-Small-Cell Lung Cancer.

Purpose: Optimal first-line systemic therapy for patients with advanced nonsquamous (nonsq) non-small-cell lung cancer (NSCLC) requires confirmation of EGFR/ ALK status, which can delay treatment. We evaluated the impact of reflex testing, defined as pathologists initiating EGFR/ ALK testing at the time of diagnosis of nonsq NSCLC, on time to treatment (TTT).

Methods: We conducted a retrospective review of patients with nonsq NSCLC with medical oncology consultation at Sunnybrook Odette Cancer Centre between March 18, 2010 and April 30, 2014.

The Use of Systemic Treatment in the Maintenance of Patients with Non-Small Cell Lung Cancer: A Systematic Review.

Introduction: Non-small cell lung cancer (NSCLC) is often diagnosed at later stages when treatment options are limited. Maintenance therapy may prolong the time to disease progression and potentially increase overall survival. Secondarily, it may increase the proportion of patients eligible for second-line therapy at the time of progression.

Clinical impact of mutation fraction in epidermal growth factor receptor mutation positive NSCLC patients.

Background: We examined clinical outcomes in a population-based cohort of EGFR mutant advanced NSCLC patients, exploring the potential role of factors including tumour EGFR mutation fraction and cellularity in predicting outcomes.

Methods: A cohort of patients with EGFR mutant advanced NSCLC was identified (N =2 93); clinical outcomes, pathologic and treatment details were collected. Tumour response was determined from radiology and clinical notes.

Retrospective review of the incidence of monitoring blood glucose levels in patients receiving corticosteroids with systemic anticancer therapy.

Background: Corticosteroids are used adjuvant to certain chemotherapy regimens, either as an antiemetic, to reduce other side effects, or to enhance cancer treatment. Additionally, they are frequently used for symptom control in cancer patients with end stage disease. Corticosteroid use may induce hyperglycemia in approximately 20-50% of patients, which may negatively affect patient outcomes.
