Pembrolizumab Utilization and Clinical Outcomes Among Patients With Advanced Melanoma in the US Community Oncology Setting: An Updated Analysis

Favorable outcomes have been observed with pembrolizumab among patients with advanced melanoma in clinical trials; however, limited evidence exists on the long-term efficacy in the real-world setting. This was an updated, retrospective observational study of adult patients with advanced (unresectable or metastatic) melanoma who initiated pembrolizumab (in any line of therapy) between January 1, 2014, and December 31, 2016, in The US Oncology Network and were followed through December 31, 2019 [median follow-up: 18.2 mo (range: 0.1–63.1 mo)]. Study data were sourced from electronic health records. Patient demographic, clinical, and treatment characteristics were assessed descriptively. Kaplan-Meier methods were used to evaluate overall survival (OS), time to treatment discontinuation, time to next treatment, physician-assessed time to tumor progression, and physician-assessed progression-free survival (rwPFS). Independent risk factors for OS and rwPFS were identified with multivariable Cox regression models. Of the 303 study-eligible patients, 119, 131, and 53 received pembrolizumab in the first-line, second-line, and third-line or beyond setting, respectively. Median OS across the study population was 29.3 months [95% confidence interval (CI): 20.3–49.7] and was the longest among those who received first-line pembrolizumab [42.8 mo (95% CI: 24.8–not reached)]. Median rwPFS across the study population was 5.1 months (95% CI: 4.0–7.6...

Purpose of review Immunotherapies such as immune checkpoint blockade have revolutionized cancer treatment, but current approaches have failed to improve outcomes in glioblastoma and other brain tumours. T cell dysfunction has emerged as one of the major barriers for the development of central nervous system (CNS)-directed immunotherapy. Here, we explore the unique requirements that T cells must fulfil to ensure immune surveillance in the CNS, and we analyse T cell dysfunction in glioblastoma (GBM) through the prism of CNS-resident immune responses. Recent findings Using comprehensive and unbiased techniques such...

Online ahead of print.ABSTRACTBACKGROUND: Advances in systemic treatment and in brain imaging have led to a higher incidence of diagnosed brain metastases. In the treatment of brain metastases, stereotactic radiotherapy and radiosurgery, systemic immunotherapy, and targeted drug therapy are important evidence-based options. In this review, we summarize the available evidence on the treatment of brain metastases of the three main types of cancer that give rise to them: non-small-cell lung cancer, breast cancer, and malignant me...

We sought to clarify if this same concern translated to linear accelerator-based SRT for BM.MATERIALS/METHODS: We retrospectively reviewed cases of SRT delivered at a single institution for BM (2004-2019). In total, 251 patients and 723 courses of treatment were analyzed on a per-treatment basis for any grade RN. R...

Bovenschen Medulloblastoma (MB), a primary tumor of the central nervous system, is among the most prevalent pediatric neoplasms. The median age of diagnosis is six. Conventional therapies include surgical resection of the tumor with subsequent radiation and chemotherapy. However, these therapies often cause severe brain damage, and still, approximately 75% of pediatric patients relapse within a few years. Because the conventional therapies cause such severe damage, especially in the pediatric developing brain, there is an urgent need for better treatment strategies such as immunotherapy, which over the years has gaine...

Radiotherapy is a mainstay of efficient treatment of brain metastases from solid tumors. Immunotherapy has improved the survival of metastatic cancer patients across many tumor types. However, targeted therapy is a feasible alternative for patients unable to continue immunotherapy or with poor outcomes of immunotherapy. The combination of radiotherapy and targeted therapy for the treatment of brain metastases has a strong theoretical underpinning, but data on the efficacy and safety of this combination is still limited. A systematic search of PubMed, Embase, Web of Science and the Cochrane library database was conducted. E...

rzeff Nicolas Meyer Anouchka Modesto Metastatic melanoma patients are at high risk of brain metastases (BM). Although intracranial control is a prognostic factor for survival, impact of local (intracranial) treatment (LT), surgery and/or radiotherapy (stereotactic or whole brain) in the era of novel therapies remains unknown. We evaluated BM incidence in melanoma patients receiving immune checkpoint inhibitors (ICI) or anti-BRAF therapy and identified prognostic factors for overall survival (OS). Clinical data and treatment patterns were retrospectively collected from all patients treated for newly diagnosed locall...

In this study, we used the UK Biobank (n = 440,185) to resolve previous ambiguities in the relationship between serum IGF-1 levels and clinical disease. We examined prospective associations of serum IGF-1 with mortality, dementia, vascular disease, diabetes, osteoporosis, and cancer, finding two generalized patterns. First, IGF-1 interacts with age to modify risk in a manner consistent with antagonistic pleiotropy; younger individuals with high IGF-1 are protected from disease, while older individuals with high IGF-1 are at increased risk for incident disease or death. Second, the association between IGF-1 and risk ...

AbstractIntroduction The study aimed to describe the brain metastases (BM) incidence, at diagnosis and follow-up, in patients initially presenting with stage III or IV melanoma and characterize their metastatic brain lesions. We also sought to describe the association of common genetic mutations and immunotherapy with BM development in advanced melanoma.MethodsUsing our institution ’s tumor registry, we identified patients with initial diagnoses of stage III and stage IV melanoma. In this cohort, we obtained BM incidence at diagnosis and follow-up, characterized the metastatic brain lesions and primary tumor’s ...

This study aimed to determine the association between: (i) cognitive decline and bone loss; and (ii) clinically significant cognitive decline on Mini Mental State Examination (MMSE) over the first 5 years and subsequent fracture risk over the following 10 years. A total of 1741 women and 620 men aged ≥65 years from the population-based Canadian Multicentre Osteoporosis Study were followed from 1997 to 2013. Over 95% of participants had normal cognition at baseline. After multivariable adjustment, cognitive decline was associated with bone loss in women but not men. Approximately 13% of participants ...
