BACKGROUND: Widely used prognostic scores, e. g., for brain or bone metastases, are based on disease- and patient-related factors such as extent of metastases, age and performance status, which were available in the databases used to develop the scores. Few groups were able to include patient-reported symptoms. In our department, all patients were assessed with the Edmonton Symptom Assessment System (ESAS, a one-sheet questionnaire addressing 11 major symptoms and wellbeing on a numeric scale of 0-10) at the time of treatment planning since 2012...

BACKGROUND: The urokinase plasminogen activator system (uPA, uPAR, PAI‑1) is upregulated in cancer and high plasma levels are associated with poor prognosis. Their interaction with hypoxia-related osteopontin (OPN) which is also overexpressed in malignant tumors suggests potential clinical relevance. However, the prognostic role of the uPA system in the radiotherapy (RT) of non-small-cell lung cancer (NSCLC), particularly in combination with OPN, has not been investigated so far. METHODS: uPA, uPAR, PAI‑1 and OPN plasma levels of 81 patients with locally advanced or metastasized NSCLC were prospectively analyzed by ELISA before RT and were correlated to clinical patient/tumor data and prognosis after RT...

PURPOSE: We evaluated the prognostic accuracy of the albumin-bilirubin (ALBI) grade and the inflammation-based index (IBI) in estimating overall survival (OS) and toxicity in patients with hepatocellular carcinoma (HCC) treated with stereotactic body radiotherapy (SBRT). MATERIALS AND METHODS: Forty patients with 47 HCC lesions with a Barcelona Clinic Liver Cancer (BCLC) classification stage B or C were treated with SBRT in 3-12 fractions. The ALBI grade and the IBI were calculated at different time points (baseline, during, at the end of treatment and at follow-up) and compared with the Child-Pugh (CP) score as well as other patient- and treatment-related parameters, concerning OS and toxicity...

PURPOSE: This study was performed to compare the acute and late toxicities between sequential (SEQ) and simultaneous integrated boost (SIB) intensity-modulated radiotherapy (IMRT) in nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS: Stage I-IVB NPC patients were randomized to receive SEQ-IMRT or SIB-IMRT. SEQ-IMRT consisted of two plans: 2 Gy × 25 fractions to low-risk planning target volume (PTV) followed by a sequential boost (2 Gy × 10 fractions) to high-risk PTV, while SIB-IMRT treated low- and high-risk PTVs with doses of 56 and 70 Gy in 33 fractions...

BACKGROUND: For several tumor entities, automated treatment planning has improved plan quality and planning efficiency, and may enable adaptive treatment approaches. Whole-pelvic prostate radiotherapy (WPRT) involves large concave target volumes, which present a challenge for volumetric arc therapy (VMAT) optimization. This study evaluates automated VMAT planning for WPRT-VMAT and compares the results with manual expert planning. METHODS: A system for fully automated multi-criterial plan generation was configured for each step of sequential-boost WPRT-VMAT, with final "autoVMAT" plans being automatically calculated by the Monaco treatment planning system (TPS; Elekta AB, Stockholm, Sweden)...

BACKGROUND AND PURPOSE: Patients with irresectable locoregional recurrent breast cancer en cuirasse (BCEC) do not have effective curative treatment options. Hyperthermia, the elevation of tumor temperature to 40-45 °C, is a well-established radio- and chemotherapy sensitizer. A total of 196 patients were treated with reirradiation and hyperthermia (reRT+HT) at two Dutch institutes from 1982-2005. The palliative effect was evaluated in terms of clinical outcome and toxicity. PATIENTS AND METHODS: All patients received previous irradiation to a median dose of 50 Gy...

BACKGROUND: In patients with prostate cancer (PCa) and biochemical progression (BP) after radical prostatectomy (RP), salvage radiotherapy (sRT) improves prostate cancer-specific survival (PCSS), but this evidence is based only on retrospective data. PATIENTS AND METHODS: In addition to our previous study of 151 patients with PCa and BP after RP, we performed univariate analyses of prostate-specific antigen (PSA) kinetics during sRT. In 11 patients with BP or initiation of hormonal treatment (HT) within 180 days after sRT, risk factors were assessed using Mann-Whitney U tests...

PURPOSE: This study aimed to test the sensitivity of a transmission detector for online dose monitoring of intensity-modulated radiation therapy (IMRT) for detecting small delivery errors. Furthermore, the correlation of changes in detector output induced by small delivery errors with other metrics commonly employed to quantify the deviations between calculated and delivered dose distributions was investigated. METHODS: Transmission detector measurements were performed at three institutions...

BACKGROUND: A comprehensive evaluation of the current national and regional radiotherapy capacity in Austria with an estimation of demands for 2020 and 2030 was performed by the Austrian Society for Radiation Oncology, Radiobiology and Medical Radiophysics (ÖGRO). MATERIALS AND METHODS: All Austrian centers provided data on the number of megavoltage (MV) units, treatment series, fractions, percentage of retreatments and complex treatment techniques as well as the daily operating hours for the year 2014...

BACKGROUND: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMAPET/CT) is a new and evolving diagnostic method in prostate cancer with special impact on treatment planning in image-guided radiotherapy (IGRT). Initial results of metabolic response in repeated PSMA PET/CTs after hypofractionated IGRT for metastatic lesions are reported here. MATERIALS AND METHODS: Of 280 patients investigated with 68Ga-PSMA PET/CT in the period from 01/2014 through 12/2016 in the authors' department, patients were selected according to the following criteria: oligometastatic disease at initial PSMA PET/CT defined as not more than five metastatic lesions, hypofractionated IGRT to all lesions, no systemic therapy in the last 6 months and during follow-up, and at least one follow-up PSMA PET after radiotherapy...

PURPOSE: The purpose of the study was to report the outcomes and late toxicities in patients younger than 60 years of age with long-term follow-up treated with low dose rate (LDR) brachytherapy for localized prostate cancer. METHODS: Between January 2000 and December 2009, 270 consecutive patients were treated with favourable localized prostate cancer; the median follow-up was 111 months (range 21-206). All patients received one implant of LDR brachytherapy. Toxicity was reported according to the Common Toxicity Criteria for Adverse Events, Version 4...

PURPOSE: Extramedullary leukaemic disease (EMD, synonym chloroma) is a rare solid manifestation of myeloid leukaemia for which the value of radiotherapy (RT) as a treatment strategy remains controversial. The aim of this study is to analyse the effectiveness of various RT doses for EMD in the modern treatment era. MATERIALS AND METHODS: Between January 2000 and June 2016, 20 patients with total of 45 lesions underwent RT for EMD at our institution. RESULTS: With a median radiation dose of 26 Gy (range 4-42 Gy), local remission could be achieved in 91% of patients (complete remission rate: 71%)...

PURPOSE: Adult medulloblastoma is a rare disease treated according to the current pediatric treatment guidelines. This retrospective analysis investigated the clinical outcomes and prognostic factors of adult medulloblastoma patients, who received multimodal therapy at our institution. METHODS: Treatment charts of all patients over the age of 15 years of age with de novo medulloblastoma, who had been treated at our institution between 2001 and 2014, were retrospectively analyzed...
