Rapid and Complete Response to Combination Anti-CTLA-4 and Anti-PD-1 Checkpoint Inhibitor Therapy in a Patient With Stage IV Refractory End-stage Epithelioid Sarcoma: A Case Report.

Epithelioid sarcoma, in the relapse-refractory setting, has limited expected survival. SMARCB1 inactivation, common in epithelioid sarcoma, causes loss of INI1 protein expression and overexpression of the cancer cell growth promoting methyltransferase enzyme, EZH2. We treated a 19-year-old male with stage IV SMARCB1 inactivated epithelioid sarcoma presenting with recurrent end stage (Eastern Cooperative Oncology Group Performance Status 4) rapidly progressing bulky disease with combination ipilimumab and nivolumab.

Interventional magnetic resonance imaging-guided subthalamic nucleus deep brain stimulation for Parkinson's disease: Patient selection.

Background: Interventional magnetic resonance imaging (iMRI) guided deep brain stimulation (DBS) for Parkinson's disease (PD) has been shown to be effective. The costs of a dedicated intraoperative MRI may be prohibitive. The procedure can also be performed in a diagnostic scanner, however this presents challenges for utilization of time when the scanner is used both as a diagnostic and an interventional unit.

Rituximab, cyclophosphamide-fractionated, vincristine, doxorubicin and dexamethasone alternating with rituximab, methotrexate and cytarabine overcomes risk features associated with inferior outcomes in treatment of newly diagnosed, high-risk diffuse large B-cell lymphoma.

Subtypes of diffuse large B-cell lymphoma (DLBCL) that have inferior outcomes after front-line therapy with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) have been identified. While it is agreed that R-CHOP is probably not adequate in these patients, there is no standard treatment approach for patients with DLBCL with high-risk features. We present results of a retrospective cohort study of high-risk DLBCL (defined as having at least one unfavorable risk factor: non-germinal center [GC] subtype by immunohistochemistry [IHC], Ki-67 ≥ 80%, high International Prognostic Index [IPI], c-MYC rearrangement) treated with R-HCVAD/R-MTX-AraC (rituximab, cyclophosphamide-fractionated, vincristine, doxorubicin and dexamethasone alternating with rituximab, methotrexate and cytarabine; R-HCVAD) as front-line therapy.

Post-treatment (not interim) positron emission tomography-computed tomography scan status is highly predictive of outcome in mantle cell lymphoma patients treated with R-HyperCVAD.

Background: Although convincing data exist regarding the prognostic utility of positron emission tomographic (PET)-computed tomographic (CT) imaging in Hodgkin lymphoma and diffuse large B-cell lymphoma, its prognostic utility both during treatment and immediately after treatment have not been systematically evaluated in a large mantle cell lymphoma (MCL) patient cohort to support its use in clinical practice.

Methods: The authors conducted a retrospective cohort study to examine the prognostic utility of PET-CT imaging in a uniform MCL patient cohort undergoing dose-intensive chemotherapy (R-HyCVAD) in the frontline setting. The primary study endpoints were progression-free survival (PFS) and overall survival (OS).
