[Empirical findings concerning transfer of dying persons]. / Empirische Befunde zur Verlegungspraxis Sterbender.

BACKGROUND: Own studies from the years 2013 and 2014 had shown that patients in hospital or inhabitants of nursing home get transferred even in their last, terminal phase of life. METHOD: In order to describe such transfers, a 27-item questionnaire was developed in 2016. This was addressed to employees from hospitals and nursing homes. The questionnaire determines the frequency of the laying (a), preferred periods (b), location (c) and influencing factors (d). 101 hospitals and 65 nursing homes of different sizes, carriers and federal states were included. RESULTS: In about 20% of the cases in the hospitals and in about 25% of the cases in nursing homes, dying patients are transferred. This would account for a total of approximately 150,000 patients or residents. Nursing homes place dying patients in hospitals. In the hospitals the relocations take place within the facility. No preferences of weekday or daytime could be identified. Acute physical deterioration of the state is identified as the central cause of displacement. In contrast, mental-psychological reasons are less significant. If relatives and other care partners are well involved, fewer relocations occur. Written patient agreements have a medium to distinct influence. Continuously insufficient staff has a stronger impact than an acute lack of personnel. RECOMMENDATIONS: Physiological deterioration of the dying person must not result in an alarm and associated solution chain. A special risk management or case management for this group could prevent misallocation. The "Advance Care Planing" passed by the Hospiz- and Pallitativgesetz in 2015 should also reduce the relocation frequency.

Immune and Inflammatory Cell Composition of Human Lung Cancer Stroma.

Recent studies indicate that the abnormal microenvironment of tumors may play a critical role in carcinogenesis, including lung cancer. We comprehensively assessed the number of stromal cells, especially immune/inflammatory cells, in lung cancer and evaluated their infiltration in cancers of different stages, types and metastatic characteristics potential. Immunohistochemical analysis of lung cancer tissue arrays containing normal and lung cancer sections was performed. This analysis was combined with cyto-/histomorphological assessment and quantification of cells to classify/subclassify tumors accurately and to perform a high throughput analysis of stromal cell composition in different types of lung cancer. In human lung cancer sections we observed a significant elevation/infiltration of total-T lymphocytes (CD3+), cytotoxic-T cells (CD8+), T-helper cells (CD4+), B cells (CD20+), macrophages (CD68+), mast cells (CD117+), mononuclear cells (CD11c+), plasma cells, activated-T cells (MUM1+), B cells, myeloid cells (PD1+) and neutrophilic granulocytes (myeloperoxidase+) compared with healthy donor specimens. We observed all of these immune cell markers in different types of lung cancers including squamous cell carcinoma, adenocarcinoma, adenosquamous cell carcinoma, small cell carcinoma, papillary adenocarcinoma, metastatic adenocarcinoma, and bronchioloalveolar carcinoma. The numbers of all tumor-associated immune cells (except MUM1+ cells) in stage III cancer specimens was significantly greater than those in stage I samples. We observed substantial stage-dependent immune cell infiltration in human lung tumors suggesting that the tumor microenvironment plays a critical role during lung carcinogenesis. Strategies for therapeutic interference with lung cancer microenvironment should consider the complexity of its immune cell composition.

Bendamustine plus rituximab versus CHOP plus rituximab as first-line treatment for patients with indolent and mantle-cell lymphomas: an open-label, multicentre, randomised, phase 3 non-inferiority trial.

BACKGROUND: Rituximab plus chemotherapy, most often CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone), is the first-line standard of care for patients with advanced indolent lymphoma, and for elderly patients with mantle-cell lymphoma. Bendamustine plus rituximab is effective for relapsed or refractory disease. We compared bendamustine plus rituximab with CHOP plus rituximab (R-CHOP) as first-line treatment for patients with indolent and mantle-cell lymphomas. METHODS: We did a prospective, multicentre, randomised, open-label, non-inferiority trial at 81 centres in Germany between Sept 1, 2003, and Aug 31, 2008. Patients aged 18 years or older with a WHO performance status of 2 or less were eligible if they had newly diagnosed stage III or IV indolent or mantle-cell lymphoma. Patients were stratified by histological lymphoma subtype, then randomly assigned according to a prespecified randomisation list to receive either intravenous bendamustine (90 mg/m(2) on days 1 and 2 of a 4-week cycle) or CHOP (cycles every 3 weeks of cyclophosphamide 750 mg/m(2), doxorubicin 50 mg/m(2), and vincristine 1.4 mg/m(2) on day 1, and prednisone 100 mg/day for 5 days) for a maximum of six cycles. Patients in both groups received rituximab 375 mg/m(2) on day 1 of each cycle. Patients and treating physicians were not masked to treatment allocation. The primary endpoint was progression-free survival, with a non-inferiority margin of 10%. Analysis was per protocol. This study is registered with ClinicalTrials.gov, number NCT00991211, and the Federal Institute for Drugs and Medical Devices of Germany, BfArM 4021335. FINDINGS: 274 patients were assigned to bendamustine plus rituximab (261 assessed) and 275 to R-CHOP (253 assessed). At median follow-up of 45 months (IQR 25-57), median progression-free survival was significantly longer in the bendamustine plus rituximab group than in the R-CHOP group (69.5 months [26.1 to not yet reached] vs 31.2 months [15.2-65.7]; hazard ratio 0.58, 95% CI 0.44-0.74; p<0.0001). Bendamustine plus rituximab was better tolerated than R-CHOP, with lower rates of alopecia (0 patients vs 245 (100%) of 245 patients who recieved ≥3 cycles; p<0.0001), haematological toxicity (77 [30%] vs 173 [68%]; p<0.0001), infections (96 [37%] vs 127 [50%]); p=0.0025), peripheral neuropathy (18 [7%] vs 73 [29%]; p<0.0001), and stomatitis (16 [6%] vs 47 [19%]; p<0.0001). Erythematous skin reactions were more common in patients in the bendamustine plus rituximab group than in those in the R-CHOP group (42 [16%] vs 23 [9%]; p=0.024). INTERPRETATION: In patients with previously untreated indolent lymphoma, bendamustine plus rituximab can be considered as a preferred first-line treatment approach to R-CHOP because of increased progression-free survival and fewer toxic effects.

Dendritic cells fused with core binding factor-beta positive acute myeloid leukaemia blast cells induce activation of cytotoxic lymphocytes.

Several reports have described various strategies of dendritic cell (DC) vaccination to induce specific T-cell responses in patients with acute myeloid leukaemia (AML). About 50-60% of AML cases blasts have chromosomal abnormalities, such as inv(16) or t(8,21), which could encode for leukaemia-specific antigenic peptide sequences, possibly presented in the context of self-major histocompatibility complex (MHC) molecules. As the co-culture of AML blasts with T lymphocytes seldom resulted in T-cell stimulation, we fused AML blasts with autologous DC to enhance this effect. The fusion cells expressed MHC class I and II, CD40, B7-1, B7-2, CD209 and several adhesion molecules. In a mixed lymphocyte hybrid reaction, the fusion cells induced the proliferation of autologous T cells. Moreover, in the special case of fusion cells established from AML blasts with the chromosomal abnormality inv(16), the autologous T lymphocytes could be primed to induce cytotoxicity against up to 70% autologous AML blasts in a effector:target ratio of 20:1. Blocking assays demonstrated that the lysis was chiefly mediated by CD8(+), CCR7(-) T lymphocytes, which could be further expanded in the form of effector memory CD8(+) T cells by repeated co-cultures with the autologous fusion cells.
