Purpose: The purpose of this study was to provide risk estimations for vaginal morbidity with regard to vaginal dilation (summarizing the use of dilators and/or sexual activity) in patients with locally advanced cervical cancer treated with definitive radiochemotherapy and image guided adaptive brachytherapy within the prospective, multi-institutional EMBRACE-I study.

Methods And Materials: Physician-assessed vaginal morbidity (National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0), use of vaginal dilators, and patient-reported sexual activity (EORTC-CX24) were prospectively assessed at baseline and during regular follow-ups.

Background And Purpose: Tools for auto-segmentation in radiotherapy are widely available, but guidelines for clinical implementation are missing. The goal was to develop a workflow for performance evaluation of three commercial auto-segmentation tools to select one candidate for clinical implementation.

Materials And Methods: One hundred patients with six treatment sites (brain, head-and-neck, thorax, abdomen, and pelvis) were included.

Background: Evidence regarding the effects of fiducials in image-guided radiotherapy (IGRT) for tumor control and acute and late toxicity is sparse.

Patients And Methods: Patients with primary low- and intermediate-risk prostate cancer, 40 with and 21 without gold fiducial markers (GFM), and treated between 2010 and 2015 were retrospectively included. The decision for or against GFM implantation took anaesthetic evaluation and patient choice into account.

Purpose: To describe a local radio-oncological treatment for patients with prostate cancer that metastasized to either the lymph nodes or distant regions.

Methods And Materials: We included 133 patients with prostate cancer that displayed either distant metastases (DM) or lymph node metastases alone (NM) and were treated between 2004 and 2019. All patients underwent computed tomography and a bone scan or 18F- or prostate-specific membrane antigen-targeted positron emission tomography.

Background: The aim of the study was to evaluate the development of treatment of primary high-risk prostate cancer in regards to biochemical no evidence of disease (bNED), acute and late gastrointestinal (GI) and genitourinary (GU) side effects.

Patients And Methods: Primary high-risk prostate cancer patients treated between 1994 and 2016 were included. Applied doses ranged from 60 to 80 Gy, with a dose of 1.

Purpose: Hypofractionated radiotherapy for prostate cancer is well established for definitive treatment, but not well defined in the postoperative setting. The purpose of this analysis was to assess oncologic outcomes and toxicity in a large cohort of patients treated with conventionally fractionated three-dimensional (3D) conformal radiotherapy (CF) and hypofractionated volumetric modulated arc therapy (HF) after radical prostatectomy.

Methods: Between 1994 and 2019, a total of 855 patients with prostate carcinoma were treated by postoperative radiotherapy using CF (total dose 65-72 Gy, single fraction 1.

Fetal inflammatory response syndrome is associated with increased neonatal morbidity and mortality. The aim of the present study was to evaluate the dynamics of the plasmatic value of pro-inflammatory cytokines: tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and neutrophil activating peptide 78 (ENA-78) and the anti-inflammatory cytokine IL-10 in the first and third day of life and the correlation with neonatal morbidities and mortality. The current research was designed as a prospective case control study included 80 neonates hospitalized at the 3rd level Neonatal Intensive Care Unit (NICU), 1st Gynecology Clinic, County Emergency Hospital, Cluj-Napoca, Romania.

Purpose: This study's objective was the comparison of external beam radiotherapy (EBRT) and I‑125 seed brachytherapy regarding clinical outcome and development of side effects.

Patients And Methods: In all, 462 localized intermediate-risk prostate cancer patients treated between 2000 and 2019 at our department using either I‑125 seed brachytherapy or EBRT with a dose of 74 or 78 Gy were included: 297 patients were treated with EBRT and 165 with seeds. Biochemical no evidence of disease (bNED) rates according to Phoenix definition as well as late gastrointestinal and urogenital side effects (EORTC/RTOG) were assessed.

Purpose: The goal of our study was comparison of external beam radiotherapy (EBRT) and I‑125 seeds brachytherapy in terms of biochemical control and development of late gastrointestinal and genitourinary side effects.

Patients And Methods: 477 low-risk prostate cancer patients treated between 2000 and 2019 at our department using either I‑125 seeds brachytherapy or EBRT with a dose of 74 or 78 Gy were reviewed for our analysis. 213 patients were treated with EBRT and 264 with seeds.

Thymoma and thymic carcinoma are thymic epithelial tumors (TETs). We performed a molecular profiling to investigate the pathogenesis of TETs and identify novel targets for therapy. We analyzed 37 thymomas (18 type A, 19 type B3) and 35 thymic carcinomas.
