ConclusionWe describe the first case of MG-LE overlap syndrome diagnosed after anti-PD1 immunotherapy for metastatic  melanoma, which appeared after radiation therapy and then relapsed after brain radiation necrosis. We hypothesized a role for brain inflammation as a trigger for MG-LE onset. Neuro-muscular junctions disease induced or revealed by checkpoint inhibitors can be challenging and requires long-term f ollow-up.

Clin Cancer Res. 2021 Jul 20:clincanres.1193.2021. doi: 10.1158/1078-0432.CCR-21-1193. Online ahead of print.ABSTRACTThe impact of liver metastases on immune checkpoint inhibitor effectiveness in patients with solid tumor malignancies has been the focus of several recent clinical and translational studies. We review the literature describing the immune functions of the liver and particularly the mechanistic observations in these studies. The initial clinical observation was that pembrolizumab appeared to be much less effective in melanoma and NSCLC patients with liver metastasis. Subsequently other clinical studies have ex...

CONCLUSIONS: This analysis suggests that treatment with SRS and immunotherapy is associated with improved OS compared to immunotherapy alone for patients with melanoma or NSCLC metastatic to the brain.PMID:34236616 | DOI:10.1007/s12094-021-02675-w

Malignant melanoma is the 5th most common cancer and stage IV melanoma accounts for approximately 4% of new melanoma diagnoses in the United States. The prognosis for regionally advanced disease is poor, but there have been numerous recent advances in the medical management of melanoma in-transit metastases. The goal of this paper is to review currently accepted treatment options for in-transit metastases and introduce emerging therapies. Therapies to be discussed include limb perfusion and infusion, immunotherapy, checkpoint inhibitors, and radiation therapy.

AbstractRadiotherapy for brain metastases has evolved tremendously over the past four decades, allowing for improved intracranial control of disease with reduced neurotoxicity. The main technological advance was provided by volumetric modulated arc therapy (VMAT), a computer-controlled delivery method that has opened the door for single-isocenter multi-metastases stereotactic radiosurgery (SRS) and hippocampal avoidance whole brain radiation therapy (HA-WBRT). Other notable advances have occurred in the combination of immune checkpoint inhibitors (ICI) and radiosurgery. When these two modalities are combined in the proper ...

This article will review background data establishing efficacy of angiogenesis inhibitors and immunotherapy in the treatment of cervical cancer as well as results of prospective studies combining targeted therapies with standard CRT with the aim of improving outcomes. In addition, the role of immunotherapy and radiation on the tumor microenvironment (TME) will be discussed.

This article reviews the mechanism of brain metastasis, challenges with treating the central nervous system, historical treatment of MBM, and outcomes in major clinical trials with targeted therapy and immunotherapy.Expert opinion: The MBM patient population now, more than ever, requires a multidisciplinary approach with indicated surgery, radiation therapy and the advancement of systemic therapies. MBM has been traditionally excluded from clinical trials for systemic therapy due to poor survival. However, recent data shows overall survival rates have significantly improved, supporting the need for more inclusion of MBM pa...

Neelu Puri Malignant melanoma is the most aggressive type of skin cancer with invasive growth patterns. In 2021, 106,110 patients are projected to be diagnosed with melanoma, out of which 7180 are expected to die. Traditional methods like surgery, radiation therapy, and chemotherapy are not effective in the treatment of metastatic and advanced melanoma. Recent approaches to treat melanoma have focused on biomarkers that play significant roles in cell growth, proliferation, migration, and survival. Several FDA-approved molecular targeted therapies such as tyrosine kinase inhibitors (TKIs) have been developed against ...

We examined the real ‐world survival impact of IT and RT combination and timing strategies.Materials and MethodsFrom the facility ‐based National Cancer Database (NCDB) data set, 3008 cases of MBM were identified between 2011 and 2015. Six treatment cohorts were identified: stereotactic radiosurgery (SRS) + IT, SRS alone, whole brain radiotherapy (WBRT) + IT, WBRT alone, IT alone, and none. Concurrent therapy was defined as IT given within 28 days before or after RT; nonconcurrent defined as IT administered within 28–90 days of RT. The co‐primary outcomes were propensity score‐adjusted overall survi...
