PURPOSE To provide additional clinical data about the re-irradiation tolerance of the spinal cord. METHODS This was a retrospective bi-institutional study of patients re-irradiated to the cervical or thoracic spinal cord with minimum follow-up of 6 months. The maximum dose (Dmax) and dose to 0.1cc (D0.1cc) were determined (magnetic resonance imaging [MRI]-defined cord) and expressed as equivalent dose in 2‑Gy fractions (EQD2) with an α/β value of 2 Gy. RESULTS All 32 patients remained free from ...

BACKGROUND/AIM The aim of this study was to analyze the survival predictions obtained from a recent graded prognostic model developed and validated in Japan. PATIENTS AND METHODS This was a retrospective single-institution analysis of 249 patients, managed with whole-brain radiotherapy for brain metastases. The sum of scores was calculated as in the Japanese study. The following parameters were included: number of brain metastases, volume of the largest lesion, sex, Karnofsky performance status,...

Background/aim Oncological care has faced several challenges during the COVID-19 pandemic, e.g. treatment delay and worsening symptoms. Patient-reported anxiety, depression and sleep quality might have changed due to these special circumstances. Therefore, we analyzed the symptom burden of patients treated with palliative radiotherapy at our center. Patients and methods A retrospective study was performed of 50 consecutive patients and the results were compared to those obtained in a previous pr...

Background: The aims of the study were to examine the rates of and reasons for unplanned hospitalization after start of palliative radiotherapy or chemoradiation (CRT), and to study whether unplanned hospitalization deteriorates patients’ prognosis. In addition, risk factors were identified. Methods: A retrospective review of 136 patients treated with palliative radiotherapy or CRT was performed. Inclusion criteria were prescribed total dose at least 30 Gy and outpatient at the start of treatmen...

Abstract Survival prediction models may serve as decision-support tools for clinicians who have to assign the right treatment to each patient, in a manner whereby harmful over- or undertreatment is avoided as much as possible. Current models differ regarding their components, the overall number of components and the weighting of individual components. Some of the components are easy to assess, such as age or primary tumor type. Others carry the risk of inter-assessor inconsistency and time-depen...

BACKGROUND/AIM The aim of this study was to analyze the survival predictions obtained from a web platform allowing for computation of the so-called Bone Metastases Ensemble Trees for Survival (BMETS). This prediction model is based on a machine learning approach and considers 27 prognostic covariates. PATIENTS AND METHODS This was a retrospective single-institution analysis of 326 patients, managed with palliative radiotherapy for bone metastases. Deviations between model-predicted survival and ...

BACKGROUND/AIM Recent studies suggested that high unintended radiation doses to the heart may reduce survival of patients with non-small-cell lung cancer (NSCLC) irradiated with curative intent. In the palliative setting, limited information is available. Therefore, we analyzed a single-institution cohort of 165 patients. PATIENTS AND METHODS Patients in this retrospective study received palliative (chemo)radiotherapy (at least 30 Gy). Typical radiation doses were 10-13 fractions of 3 Gy and 15 ...

Objectives The objective of this study were to improve the 3-tiered, purely biomarker-based LabBM score, which predicts the survival of patients with brain metastases, by adding the well-established prognostic factor performance status (PS), and to define its role in comparison with the recently proposed Extracranial-Graded Prognostic Assessment score, which is based on the well-known Diagnosis-specific Graded Prognostic Assessment and 2 of the same biomarkers. Materials and methods This was a r...
