How to optimize the CAR-T Cell therapy process? A group concept mapping analysis of preconditions for a frictionless process from a German multistakeholder perspective.

Introduction: Treatment with chimeric antigen receptor T (CAR-T) cells involves a large number of interdisciplinary stakeholders and is associated with complex processes ranging from patient-specific production to follow-up care. Due to the complexity, maximum process optimization is required in order to avoid efficiency losses. This study aimed at systematically determining the preconditions for a frictionless flow of the CAR-T process by surveying the stakeholders involved.

Factors influencing community acceptability of mass drug administration for the elimination of onchocerciasis in the Asante Akim South Municipal, Ghana.

Introduction: Onchocerciasis is one of the eleven neglected tropical diseases (NTDs) recently targeted by the World Health Organization (WHO) for elimination. Mass drug administration (MDA) of ivermectin has become the main intervention for reducing the burden of onchocerciasis and controlling its transmission. However, despite the considerable gains in the fight against onchocerciasis in Ghana, the infection remains endemic in some communities.

Microbial contamination and composition of oral samples subjected to clinical whole genome sequencing.

Biological material from the oral cavity is an excellent source of samples for genetic diagnostics. This is because collection is quick, easy-to-access, and non-invasive. We have set-up clinical whole genome sequence testing for patients with suspected hereditary disease.

Synthetic antibody-derived immunopeptide provides neuroprotection in glaucoma through molecular interaction with retinal protein histone H3.1.

Glaucoma is a group of optic neuropathies characterized by the progressive degeneration of retinal ganglion cells (RGCs) as well as their axons leading to irreversible loss of sight. Medical management of the intraocular pressure (IOP) still represents the gold standard in glaucoma therapy, which only manages a single risk factor and does not directly address the neurodegenerative component of this eye disease. Recently, our group showed that antibody-derived immunopeptides (encoding complementarity-determining regions, CDRs) provide attractive glaucoma medication candidates and directly interfere its pathogenic mechanisms by different modes of action.

Increased Prostaglandin E2 in Brainstem Respiratory Centers Is Associated With Inhibition of Breathing Movements in Fetal Sheep Exposed to Progressive Systemic Inflammation.

Background: Preterm newborns commonly experience apnoeas after birth and require respiratory stimulants and support. Antenatal inflammation is a common antecedent of preterm birth and inflammatory mediators, particularly prostaglandin E2 (PGE), are associated with inhibition of vital brainstem respiratory centers. In this study, we tested the hypothesis that exposure to antenatal inflammation inhibits fetal breathing movements (FBMs) and increases inflammation and PGE levels in brainstem respiratory centers, cerebrospinal fluid (CSF) and blood plasma.

Final Results of a Phase I/II Trial of the Combination Bendamustine and Rituximab With Temsirolimus (BeRT) in Relapsed Mantle Cell Lymphoma and Follicular Lymphoma.

In this phase I/II study, we explored the combination of Temsirolimus with Bendamustine and Rituximab (BeRT) in patients with relapsed or refractory (r/r) follicular lymphoma (FL) or mantle cell lymphoma (MCL). Patients with 1 to 3 previous therapies received Bendamustine (90 mg/m, day 1 + 2) and Rituximab (375 mg/m, day 1) with Temsirolimus in doses from 25 to 75 mg in phase I and 50 mg Temsirolimus in phase II, added on day 1, 8, 15 of a 28 days cycle. The primary endpoint of the phase II was ORR at the end of treatment.

Doxorubicin, vinblastine, dacarbazine and lenalidomide for older Hodgkin lymphoma patients: final results of a German Hodgkin Study Group (GHSG) phase-I trial.

About 30% of all Hodgkin lymphoma (HL) patients are ≥60 years old. As lenalidomide has promising single agent activity in multiple relapsed HL, we replaced bleomycin in ABVD with lenalidomide in this phase-I trial. Patients aged ≥60 years with early-unfavourable- or advanced-stage HL (Eastern Cooperative Oncology Group performance status ≤2, Cumulative Illness Rating Scale for Geriatrics score 0-7) received 4-8 cycles of AVD (doxorubicin, vinblastine, dacarbazine) and lenalidomide in escalation with overdose control.

Rigor prophylaxis in stage IV melanoma and renal cell carcinoma patients treated with high dose IL-2.

Background: Rigors are a significant adverse event during interleukin-2 (IL2) therapy for metastatic melanoma and renal cell carcinoma. Meperidine has been a mainstay for rigor prophylaxis but there is a paucity of data regarding possible alternatives.

Methods: Ninety one patients receiving IL2 therapy for metastatic renal cell carcinoma and melanoma at Huntsman Cancer institute (HCI), Utah from May 2009 to October 2016 were retrospectively evaluated for rigor prophylaxis.

[Myelodysplastic syndrome, acute leukemia and stem cell transplantation].

Myelodysplastic syndromes (MDS) represent a heterogeneous group of clonal hematopoietic stem cell disorders. They are characterized by inefficient hematopoiesis leading to peripheral cytopenia of one or more lineages and a variable risk of transformation into acute myeloid leukemia. They may either arise de novo as well as following exposition to environmental toxins, previous radiotherapy or chemotherapy or in the context of autoinflammatory diseases and related therapy.

Prostate cancer infiltrating the bladder sphincter successfully treated with Electrochemotherapy: a case report.

We demonstrate feasibility and safety of Electrochemotherapy for treatment of a prostate cancer (PCa) with infiltration of the urethral sphincter. The patient remained continent and potent, toxicity was low, and 6 months of follow-up showed no cancer activity. We conclude that Electrochemotherapy should be further evaluated as treatment strategy for locally advanced PCa.

Hematological alterations can often be observed during rheumatic diseases. The effects can be clinically severe, ranging from anemia of different grades of severity, through increased risk of hemorrhage due to thrombocytopenia up to severe infections as a result of high-grade leukocytopenia. The clinical sequelae for patients are predominantly determined by the extent of cytopenia.

Induced pluripotent stem cell modelling of HLHS underlines the contribution of dysfunctional NOTCH signalling to impaired cardiogenesis.

Hypoplastic left heart syndrome (HLHS) is among the most severe forms of congenital heart disease. Although the consensus view is that reduced flow through the left heart during development is a key factor in the development of the condition, the molecular mechanisms leading to hypoplasia of left heart structures are unknown. We have generated induced pluripotent stem cells (iPSC) from five HLHS patients and two unaffected controls, differentiated these to cardiomyocytes and identified reproducible in vitro cellular and functional correlates of the HLHS phenotype.

High-dose methotrexate-based immuno-chemotherapy for elderly primary CNS lymphoma patients (PRIMAIN study).

To investigate immuno-chemotherapy for elderly immuno-competent patients (⩾65 years) with newly diagnosed primary central nervous system lymphoma, we conducted a multicentre single-arm trial. One cycle consisted of rituximab (375 mg/m, days 1, 15, 29), high-dose methotrexate (3 g/m days 2, 16, 30), procarbazine (60 mg/m days 2-11) and lomustine (110 mg/m, day 2)-R-MPL protocol. Owing to infectious complications, we omitted lomustine during the study and consecutive patients were treated with the R-MP protocol.

Resection of central nervous system lymphoma: a paradigm shift?

Central nervous system lymphomas (CNSL) are traditionally regarded as non-surgically treated tumors with a poor prognosis. Usually, only stereotactic biopsy is performed to establish the diagnosis, and most patients show disease progression within half a year. A recent study questioned this view, since patients who had surgical resection of CNSL manifestations prior to adjuvant therapy reportedly had a better outcome than patients who had biopsy only.

Stabilizing an Embolized Pre-stent into the Right Ventricle During MELODY Valve Implantation.

Stent embolization is a complication that usually requires surgical extraction. We report a case where the covered stent used in MELODY valve trans-catheter pulmonary valve placement embolized to the right ventricle after being fully dilated on a 24-m-diameter balloon. After several unsuccessful attempts trying to capture it back or push it forward to the intended landing zone, we succeeded in deploying another stent straddling the embolized stent to anchor both of them in the main pulmonary artery.

Does the Implantation Technique for Totally Implantable Venous Access Ports (TIVAPs) Influence Long-Term Outcome?

Background: Totally implantable venous access ports (TIVAP) are eventually explanted for various reasons, related or unrelated to the implantation technique used. Having more information on long-term explantation would help improve placement techniques.

Methods: From a series of 1572 cancer patients who had TIVAPs implanted in our center with the cutdown technique or Seldinger technique, we studied the 542 patients who returned to us to have their TIVAP explanted after 70 days or more.

Safety and efficacy of Temsirolimus in combination with Bendamustine and Rituximab in relapsed mantle cell and follicular lymphoma.

In this phase I/II study, we explored the combination of Temsirolimus with Bendamustine and Rituximab (BeRT) in patients with r/r follicular lymphoma (FL) or mantle cell lymphoma (MCL). Patients with 1-3 prior therapies received Bendamustine (90 mg/m(2), day 1+2) and Rituximab (375 mg/m(2), day 1) with Temsirolimus in doses from 25 to 75 mg added on day 1, 8, 15 of a 28-day cycle. Fifteen (11 MCL, 4 FL) patients were included in the phase I.

Autologous stem cell transplantation in HIV-related lymphoma in the rituximab era - a feasibility study in a monocentric cohort.

Introduction: Since the introduction of highly active antiretroviral therapy (HAART) (1) and later on the availability of anti-CD20 monoclonal antibody treatment (2), the therapeutic options as well as the prognosis of AIDS related lymphoma (ARL) have been improved. There is however no uniform agreement on how to treat patients who do not achieve a partial remission, who experience a relapse or who have very aggressive subtypes. Autologous hematopoietic stem cell transplantation (ASCT) has become an option for those patients.

Long-term results after proactive management for locoregional control in patients with colonic cancer at high risk of peritoneal metastases.

Purpose: A major problem in treating patients with peritoneal spread from colorectal cancer is that at diagnosis wide peritoneal involvement often precludes all curative attempts. A possible solution is to identify those patients at risk for peritoneal metastases and intervene early to prevent locoregional disease spread before it develops and, thus, to improve outcome.

Methods: We analyzed long-term results from a previous study and compared outcomes in 25 patients with advanced colon cancer considered at high risk for peritoneal spread (pT3/pT4 and mucinous or signet ring cell histology) prospectively included and managed with a proactive surgical approach including target organ resection for peritoneal spread plus hyperthermic intraperitoneal chemotherapy (HIPEC) and in 50 retrospectively well-matched controls who underwent standard surgical resection during the same period and in the same hospital by different surgical teams.

Prophylactic use of pegfilgrastim in patients treated with a nitrosourea and teniposide for recurrent glioma.

Study Objective: As chemotherapy with teniposide and a nitrosourea is commonly used for the treatment of patients with recurrent glioma but can be associated with severe myelotoxicity, we sought to determine if prophylactic administration of pegfilgrastim could reduce leukopenia or infectious complications in patients receiving this chemotherapeutic regimen.

Design: Retrospective medical record review.

Setting: University-affiliated neurooncology hospital in Frankfurt, Germany.

Comparison of acute toxicity and mortality after two different dosing regimens of high-dose interleukin-2 for patients with metastatic melanoma.

We compared acute toxicity, drug exposure, in-hospital mortality, and inpatient length of stay between two currently recommended dosing protocols (from the National Comprehensive Cancer Network Guidelines) of high-dose interleukin-2 (IL-2) treatment for patients with metastatic melanoma. Patients with metastatic melanoma who received high-dose IL-2 treatment between 2003 and 2010 were identified. Chemotherapy orders, electronic medical records, paper medical charts, and patient discharge summaries were reviewed retrospectively.

Prognosis of patients with primary central nervous system lymphoma after high-dose chemotherapy followed by autologous stem cell transplantation.

High-dose chemotherapy followed by autologous stem cell transplantation has been shown to be feasible and highly effective in newly diagnosed primary central nervous system lymphoma. In this retrospective multicenter study, we investigated prognosis and baseline risk factors in patients with primary central nervous system lymphoma who underwent this treatment approach. We retrospectively analyzed 105 immunocompetent patients with primary central nervous system lymphoma who underwent high-dose chemotherapy followed by autologous stem cell transplantation with or without whole brain radiotherapy as first-line consolidation treated at 12 German centers between 1997 and 2011.
