The Real-World Clinical Outcomes of Heavily Pretreated HER2+ and HER2-Low Metastatic Breast Cancer Patients Treated with Trastuzumab Deruxtecan at a Single Centre.

Background: Trastuzumab deruxtecan (TDXd) is an antibody-drug conjugate that has demonstrated impressive activity in randomized controlled clinical trials in the context of patients with HER2-amplified and HER2-low metastatic breast cancer. We aimed to review the activity and adverse event profile of TDXd in heavily pretreated breast cancer patients in real practice.

Methods: We describe a single-center retrospective case series of metastatic breast cancer patients who were treated with TDXd.

Utilization and Safety of Ipilimumab Plus Nivolumab in a Real-World Cohort of Metastatic Renal Cell Carcinoma Patients.

Introduction: Ipilimumab plus nivolumab was associated with a survival benefit in a phase III clinical trial of first-line treatment for metastatic renal cell carcinoma (mRCC). In this study, mRCC patients from the Canadian Kidney Cancer Information System (CKCis) database who received first-line ipilimumab plus nivolumab were analyzed to determine the safety and outcomes in a real-world setting.

Patients And Methods: Patients who received ipilimumab plus nivolumab as first-line therapy for mRCC in CKCis, were identified, and the amount of treatment received, discontinuation rates, and reasons for discontinuing treatment were determined.

B-cell cytopenia and time to last B-cell-depleting therapy predict response to SARS-COV-2 vaccines in patients with lymphoproliferative disorders.

Patients with B-non-Hodgkin lymphoma (NHL) are at increased risk of morbidity and mortality from SARS-CoV-2. We investigated the relationship between B cell cytopenia and the SARS-CoV-2 vaccine response in B-NHL patients. We measured anti-RBD antibodies and the lymphocyte immunophenotype in 19 controls, 22 lymphoma patients on observation (cohort 1) and 55 lymphoma patients receiving their vaccines post B-cell depleting therapy (cohort 2).

Stereotactic Radiotherapy for Oligoprogression in Metastatic Renal Cell Cancer Patients Receiving Tyrosine Kinase Inhibitor Therapy: A Phase 2 Prospective Multicenter Study.

Background: Despite the paucity of prospective evidence, stereotactic radiotherapy (SRT) is increasingly being considered in the setting of oligoprogression to delay the need to change systemic therapy.

Objective: To determine the local control (LC), progression-free survival (PFS), cumulative incidence of changing systemic therapy, and overall survival (OS) after SRT to oligoprogressive metastatic renal cell carcinoma (mRCC) lesions in patients who are on tyrosine kinase inhibitor (TKI) therapy.

Design, Setting, And Participants: A prospective multicenter study was performed to evaluate the use of SRT in oligoprogressive mRCC patients.
