PURPOSE: To develop a fully automated procedure for multicriterial volumetric modulated arc therapy (VMAT) treatment planning (autoVMAT) for stage III/IV non-small cell lung cancer (NSCLC) patients treated with curative intent. MATERIALS AND METHODS: After configuring the developed autoVMAT system for NSCLC, autoVMAT plans were compared with manually generated clinically delivered intensity-modulated radiotherapy (IMRT) plans for 41 patients. AutoVMAT plans were also compared to manually generated VMAT plans in the absence of time pressure...

PURPOSE: Early inflammation is a major factor of mucosal reactions to radiotherapy. Pentoxifylline administration resulted in a significant amelioration of radiation-induced oral mucositis in the mouse tongue model. The underlying mechanisms may be related to the immunomodulatory properties of the drug. The present study hence focuses on the manifestation of early inflammatory changes in mouse tongue during daily fractionated irradiation and their potential modulation by pentoxifylline...

PURPOSE: To design and apply a framework for predicting symptomatic radiation pneumonitis in patients undergoing thoracic radiation, using both pretreatment anatomic and perfused lung dose-volume parameters. MATERIALS AND METHODS: Radiation treatment planning CT scans were coregistered with pretreatment [(99m)Tc]MAA perfusion SPECT/CT scans of 20 patients who underwent definitive thoracic radiation. Clinical radiation pneumonitis was defined as grade ≥ 2 (CTCAE v4 grading system)...

Quality assurance (QA) guidelines are essential to provide uniform execution of clinical trials with uniform quality hyperthermia treatments. This document outlines the requirements for appropriate QA of all current superficial heating equipment including electromagnetic (radiative and capacitive), ultrasound, and infrared heating techniques. Detailed instructions are provided how to characterize and document the performance of these hyperthermia applicators in order to apply reproducible hyperthermia treatments of uniform high quality...

OBJECTIVE: The TNM 8 lung cancer staging system reclassifies patients with a solitary extrathoracic metastasis as M1b and two or more extrathoracic metastases as M1c. This study investigates the clinical relevance of this change. METHODS: Advanced lung cancer patients were retrospectively restaged according to the TNM8 M1b and M1c classifiers. Overall survival was compared in M1b and M1c patients staged with and without PET-CT. We then summarized the TNM 8 staging classification and the relevant literature on the treatment of oligometastatic lung cancer...

BACKGROUND: Radiation therapy (RT) comprises a key component in the treatment of breast cancer. Radiation-induced skin toxicity is the major adverse event experienced by patients; however, radiodermatitis (RD) prevention and management remains trivial. It is proven that photobiomodulation (PBM) therapy using light-emitting diode (LED) increases wound healing and depicts an anti-inflammatory effect. This single-institute study evaluates the beneficial role of PBM-LED in preventing/reducing RD during breast cancer RT...

BACKGROUND: In this randomized multicenter trial, we compared the effect of a lower single dose of 0.5 Gy vs. a standard single dose of 1 Gy concerning pain relief and quality of life, while maintaining a uniform total dose of 6 Gy. On the basis of laboratory observations, the lower single dose would be expected to be more effective. PATIENTS AND METHODS: A total of 127 patients suffering from painful heel spur were randomized: Patients in the standard group were treated with single fractions of 6 × 1 Gy twice a week, while the experimental group was treated with single fractions of 12 × 0...

BACKGROUND: The aim of the study was to identify factors significantly associated with the occurrence of unintended treatment interruptions in adjuvant breast cancer radiotherapy. PATIENTS AND METHODS: Patients treated with postoperative radiotherapy of the breast or chest wall between March 2014 and August 2016 were evaluated. The radiotherapy regimens and techniques applied were either conventional fractionation (CF; 28 daily fractions of 1.8 Gy or 25 fractions of 2...

PURPOSE: To report our experience with EBRT combined with limb-sparing surgery in elderly patients (>70 years) with primary extremity soft tissue sarcomas (STS). METHODS: Retrospectively analyzed were 35 patients (m:f 18:17, median 78 years) who all presented in primary situation without nodal/distant metastases (Charlson score 0/1 in 18 patients; ≥2 in 17 patients). Median tumor size was 10 cm, mainly located in lower limb (83%). Stage at presentation (UICC7th) was Ib:3%, 2a:20%, 2b:20%, and 3:57%...

BACKGROUND: This treatment planning study analyzes dose coverage and dose to organs at risk (OAR) in intensity-modulated radiotherapy (IMRT) of rectal cancer and compares prone vs. supine positioning as well as the effect of dose optimization for the small bowel (SB) by additional dose constraints in the inverse planning process. PATIENTS AND METHODS: Based on the CT datasets of ten male patients in both prone and supine position, a total of four different IMRT plans were created for each patient...

OBJECTIVE: In image-guided EBRT of the prostate, transperineal ultrasound (US) probes exert pressure on the perineum both during planning and treatment. Through tissue deformation and relaxation, this causes target and risk organ displacement and drift. In this study, prefraction shift and intrafraction drift of the prostate are quantified during robotic transperineal 4DUS. METHODS: The position of the prostate was recorded for different positions of the probe before treatment in 10 patients (16 series of measurements)...

BACKGROUND: Temozolomide-(TMZ)-based chemoradiotherapy defines the current gold standard for the treatment of newly diagnosed glioblastoma. Data regarding the influence of TMZ dose density during chemoradiotherapy are currently not available. We retrospectively compared outcomes in patients receiving no TMZ, TMZ during radiotherapy on radiotherapy days only, and TMZ constantly 7 days a week. PATIENTS AND METHODS: From 2002-2012, a total of 432 patients with newly diagnosed glioblastoma received radiotherapy in our department: 118 patients had radiotherapy alone, 210 had chemoradiotherapy with TMZ (75 mg/m(2)) daily (7/7), and 104 with TMZ only on radiotherapy days (5/7)...

BACKGROUND: This study aimed to analyse the feasibility and acute toxicity of radical hypo-fractionated radiotherapy (RT) for elderly patients with non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: We conducted a retrospective evaluation of treatment with volumetric modulated arc therapy (VMAT) of elderly patients affected by stage III inoperable NSCLC. The dose prescription was 56 Gy in 20 fractions, 55 Gy in 22 fractions, or 50 Gy in 20 fractions...

PURPOSE: To present the feasibility and complications of transperineal fiducial marker implantation in prostate cancer patients undergoing image-guided radiotherapy (IGRT) METHODS AND MATERIALS: Between November 2011 and April 2016, three radiopaque, gold-plated markers were transperineally implanted into the prostate of 300 patients under transrectal ultrasound guidance and with local anaesthesia. A week after the procedure patients filled in a questionnaire regarding pain, dysuria, urinary frequency, nocturia, rectal bleeding, hematuria, hematospermia or fever symptoms caused by the implantation...

BACKGROUND: Stereotactic body radiotherapy (SBRT) in pancreatic cancer can be limited by its proximity to organs at risk (OAR). In this analysis, we evaluated the toxicity and efficacy of two different treatment approaches in patients with locally recurrent or oligometastatic pancreatic cancer. MATERIALS AND METHODS: According to the prescription method, patients were divided in two cohorts (C1 and C2). The planning target volume (PTV) was created through a 4 mm expansion of the internal target volume...

BACKGROUND: Complementary and alternative medicine (CAM) are gaining in importance, but objective data are mostly missing. However, in previous trials, methods such as acupuncture showed significant advantages compared to standard therapies. Thus, the aim was to evaluate most frequently used methods, their significance and the general acceptance amongst cancer patients undergoing radiotherapy (RT). METHODS: A questionnaire of 18 questions based on the categorical classification released by the National Centre for Complementary and Integrative Health was developed...
