Introduction: CDK4/6 inhibitors (ribociclib, palbociclib and abemaciclib) are 1st line therapy in metastatic breast cancer (MBC). No comparative data exists between agents regarding toxicity or efficacy.
Methods: A retrospective study was performed at our tertiary referral centre evaluating patients on a CDK4/6 inhibitor for MBC between July 2017 and December 2021.
Anti-programmed cell death protein 1 (PD1) antibodies, pembrolizumab and nivolumab, alone or in combination with ipilimumab, have become standard treatment for melanoma and multiple other malignancies. Neurological adverse effects are rare and have not been well characterized to date. Patients who developed neurological adverse effects while being treated with PD1, alone or in combination with ipilimumab, were retrospectively identified from 10 cancer centers.

The study aims to analyze the outcome of patients with ITM treated with ICI based on data from a large cohort of patients treated at international referral clinics.
Methods: A multicenter retrospective cohort study of patients treated between January 2015 and December 2020 from Australia, Europe, and the USA, evaluating treatment with ICI for ITM with or without nodal involvement (AJCC8 N1c, N2c, and N3c) and without distant disease (M0).
Introduction: Immune-related hepatitis is an adverse effect following treatment with immune-checkpoint inhibitors, such as ipilimumab, nivolumab and pembrolizumab. International guidelines advise on the use of corticosteroids as first-line treatment, although guidance on how to treat cases resistant to corticosteroids is limited. We aimed to evaluate the presentation and management of patients with grade 3-4 immune-related hepatitis, following treatment with immune-checkpoint inhibitors for stage 4 or unresectable or stage 3 melanoma, with a particular focus on steroid-refractory cases.

However, the immune related toxicity associated with these agents can be serious, and the long-term implications are yet to be defined especially in the adjuvant setting. We report, to our knowledge, the first case of anti-PD-1-induced eosinophilic asthma in a melanoma patient treated with adjuvant pembrolizumab.

Objectives: To determine the efficacy and toxicity of PD-1 monotherapy in different ethnic groups.
Methods: Clinical data for patients with unresectable or advanced melanoma treated with anti-PD-1 monotherapy between 2009 and 2019 were collected retrospectively from five independent institutions in the USA, Australia and China.
Purpose: Programmed cell death receptor-1 (PD-1) inhibitors are frontline therapy in advanced melanoma. Severe immune-related adverse effects (irAEs) often require immunosuppressive treatment with glucocorticoids (GCCs), but GCC use and its correlation with patient survival outcomes during anti-PD-1 monotherapy remains unclear.
Experimental Design: In this multicenter retrospective analysis, patients treated with anti-PD-1 monotherapy between 2009 and 2019 and detailed GCC use, data were identified from five independent cohorts, with median follow-up time of 206 weeks.
Purpose: Combination immunotherapy with nivolumab and ipilimumab has a high initial response rate in advanced melanoma; however, up to 55% of patients later progress. The efficacy and safety of ipilimumab re-induction in the setting of acquired resistance (AR) to combination immunotherapy is unknown.
Methods: Patients with advanced melanoma who initially achieved a complete response, partial response or sustained stable disease to induction combination immunotherapy then progressed and were reinduced with ipilimumab (alone or in combination with anti-PD-1) and were analysed retrospectively.
Background: Adjuvant targeted therapy (TT) improves relapse free survival in patients with resected BRAF mutant stage III melanoma. The outcomes and optimal management of patients who relapse after adjuvant TT is unknown.
Methods: Patients from twenty-one centres with recurrent melanoma after adjuvant TT were included.
Rapid production of neutralizing antibody can be critical for limiting the spread of infection. Such early antibody results when B-cell blasts mature directly to plasmablasts without forming germinal centers. These extrafollicular responses can involve Ig class switch recombination (CSR), producing antibody that can readily disseminate through infected tissues.

Current immunosuppressive regimens based on cyclophosphamide have significantly improved survival in patients with these conditions. However, such treatments are toxic, increase the risk of infection and do not cure the disease; fresh approaches are, therefore, required.

We have therefore examined whether imatinib mesylate can delay relapse and postpone the requirement for DLI in 22 patients with chronic myeloid leukemia (CML) allografted using a reduced-intensity regimen. Imatinib was commenced on day + 35 and continued until 1 year after transplantation.
