Purpose: Guidelines recommend a structured symptom screening (SC) for especially advanced cancer patients (CPs). The aim of this multicenter German prospective quality assurance project KeSBa (Kennzahl Symptom- und Belastungserfassung) was to gain knowledge on SC procedures in Oncology Centers (OCs) for advanced cancer patients and a first impression on the consequences of SC. Methods: The KeSBa project consisted of three phases: pilot, 3 months screening and feedback phase. Participating OCs decided to use either the Minimal Documentation System (MIDOS) or the Integrated Palliative care Outcome Scale (IPOS) and defined the cutoff values for positive screening results. Results: Out of 172 certified German OCs, 40 (23%) participated in the KeSBa pilot phase, 29 (16.8%) in the 3 months screening phase using MIDOS (n = 18, 58.6%) or IPOS (n = 11, 41.3%) and in the feedback round. 25/29 performed paper-based screening (86.2%). 2.963 CPs were screened. Results were documented for 1255 (42.2%, SC +) positive and 874 (29.5%, SC–) negative screenings depending on the center´s schedules: 452 SC + CPs (28.4%) and 42 SC– CPs (2.6%) had contact to specialized palliative care or other supportive specialist teams afterwards, 458 SC + CPs (28.8%) and 605 SC– CPs (38.1%) remained in standard oncology care. In the feedback round missing resources (personal and IT) and improved communication were mentioned most often. Conclusion: Routine SC is feasible in advanced CPs treated in OCs but associated with considerable workload. In 42.2% of CPs SC was classified as positive, indicating the need of further diagnostics or professional judgment. SC requires staff and IT resources. [ABSTRACT FROM AUTHOR]

Background: Analysis of circulating free DNA (cfDNA) is a promising tool for personalized management of colorectal cancer (CRC) patients. Untargeted cfDNA analysis using whole-genome sequencing (WGS) does not need a priori knowledge of the patient´s mutation profile. Methods: Here we established LIquid biopsy Fragmentation, Epigenetic signature and Copy Number Alteration analysis (LIFE-CNA) using WGS with ~ 6× coverage for detection of circulating tumor DNA (ctDNA) in CRC patients as a marker for CRC detection and monitoring. Results: We describe the analytical validity and a clinical proof-of-concept of LIFE-CNA using a total of 259 plasma samples collected from 50 patients with stage I-IV CRC and 61 healthy controls. To reliably distinguish CRC patients from healthy controls, we determined cutoffs for the detection of ctDNA based on global and regional cfDNA fragmentation patterns, transcriptionally active chromatin sites, and somatic copy number alterations. We further combined global and regional fragmentation pattern into a machine learning (ML) classifier to accurately predict ctDNA for cancer detection. By following individual patients throughout their course of disease, we show that LIFE-CNA enables the reliable prediction of response or resistance to treatment up to 3.5 months before commonly used CEA. Conclusion: In summary, we developed and validated a sensitive and cost-effective method for untargeted ctDNA detection at diagnosis as well as for treatment monitoring of all CRC patients based on genetic as well as non-genetic tumor-specific cfDNA features. Thus, once sensitivity and specificity have been externally validated, LIFE-CNA has the potential to be implemented into clinical practice. To the best of our knowledge, this is the first study to consider multiple genetic and non-genetic cfDNA features in combination with ML classifiers and to evaluate their potential in both cancer detection and treatment monitoring.

Background: Vaccinations have the potential to significantly lower the burden of disease for many major infections in the high-risk population of hematological and oncological patients. In this regard Shingrix
® , an inactivated Varicella Zoster Virus vaccine, received market approval in the European Union in March 2018, after prior US approval in October 2017, and recommendations specifically state immunocompromised, including oncological, patients. As vaccination rates are considered to be poor in oncological patients, determining the current vaccination rates for Shingrix® two years after market approval is important in defining the need for intervention to bring this potentially high-impact vaccine to the patients. Methods: We analyzed data of the EVO Study to provide data for Herpes zoster vaccination rates in oncological patients. The EVO Study was an interventional study evaluating the potential of increasing vaccination rates of specified must-have vaccinations by an instructional card in the oncological setting. Numbers presented in this publication merged baseline data and follow-up data of the control group; hence data not affected by the intervention. Results: Data of 370 patients were analyzed; 21.1% with hematological malignancies and 78.9% with solid cancer. Only 3.0% were vaccinated with Shingrix® . Patients with hematological malignancy were more likely to be vaccinated than those with solid cancer (7.7 vs. 1.7%). Conclusion: Despite clear recommendations and a pressing need in the high-risk population of hematological and oncological patients, the vast majority of patients are still left without vaccine protection against Herpes zoster by Shingrix® .

Purpose: Cancer and its treatment-related side effects induce loss of physical performance. This study evaluated the effects of multimodal aerobic and strength exercises on physical performance in hospitalized cancer patients while receiving myeloablative chemotherapy. Methods: In this prospective pilot study, 48 evaluable patients were randomly assigned to a training (TG, n = 24) or control (CG, n = 24) group. The TG performed an individually supervised exercise program five times a week with ergometer training and strength exercises for 20 min each during the hospitalization period for chemotherapy. The CG received standard physiotherapy. Physical performance was evaluated using spiroergometry, lung function, and muscle strength testing. Treatment-related side effects were assessed by daily interviews, quality of life by EORTC-QLQ-C30, and fatigue using the Modified Fatigue Impact Scale (MFIS) questionnaire. Results: Physical performance significantly increased in the TG (8.96 ± 24 W) and decreased in the CG (−7.24 ± 20 W, p = 0.02). At 2-mmol/ml blood lactate concentration, the TG achieved significantly increased oxygen consumption ( p = 0.03) and expiratory minute ventilation ( p = 0.04) compared to the CG. Furthermore, physical functioning increased significantly in the TG ( p = 0.04). Patients in the TG required less antiemetics ( p = 0.01) and experienced significantly less fatigue ( p = 0.04), although MFIS analysis was not able to detect this beneficial effect. Patients of the CG displayed higher impairments of cognitive ( p = 0.02) and psychosocial function ( p = 0.03) after chemotherapy. No adverse events due to the study intervention were observed. Conclusions: Multimodal exercise has beneficial effects on physical performance, physical functioning, and treatment-related symptoms even during myeloablative chemotherapy. We suggest an enhanced physical activity intervention program during hospitalization of cancer patients. [ABSTRACT FROM AUTHOR]

Purpose: Leptomeningeal metastases (LM) are associated with very poor prognosis and data on outcome are limited. We evaluated prognostic factors and treatment options in patients (pts) with LM of different malignancies in a single center experience. Methods: Single center data on characteristics, treatment and outcome of 135 consecutive pts (73 solid tumors and 62 hematologic malignancies) with LM between 1989 and 2005 were retrospectively analyzed. Results: Treatment consisted of systemic chemotherapy (SC) plus intrathecal chemotherapy (ITC) in 28%, ITC alone in 22%, radiotherapy (RT) plus ITC in 12% and other modalities (SC, RT, SC + RT) in 7%. Thirteen percent of pts received supportive care only (4% not evaluable on treatment). Median survival from diagnosis of LM was 2.5 months. Univariate analysis revealed age >50, interval between diagnosis of primary tumor and LM ≤12 months, lung cancer and malignant melanoma, and Karnofsky performance status ≤70 as significant negative predictors for overall survival. Positive predictive factors were response in cerebrospinal fluid and application of SC. In multivariate analysis, only SC was significantly associated with longer median survival (5.6 vs. 1.7 months). Conclusions: In patients with LM an age >50, performance status ≤70%, interval between diagnosis of primary tumor and LM ≤12 months, primary tumor (lung cancer, malignant melanoma) and lack of cytologic response present negative prognostic factors. Systemic chemotherapy is significantly associated with longer survival time than local treatment modalities. [ABSTRACT FROM AUTHOR]
