The purpose of this study was to determine the detection rate distant metastasis and synchronous cancer, comparing clinically used imaging strategies based on chest x-ray + head neck MRI (CXR/MRI) CT (CHCT/MRI) with <sup>18</sup>F-FDG PET/CT upfront in diagnostic workup patients oral, pharyngeal, or laryngeal cancer. <b>Methods:</b> This a prospective cohort paired data. Consecutive histologically verified primary squamous cell carcinoma at Odense University Hospital from September 2013...

This study aimed to compare contrast-enhanced CT (CE-CT) and 18F-FDG PET/CT for response monitoring in metastatic breast cancer using the standardized evaluation criteria RECIST 1.1 PERCIST. The objective was examine whether progressive disease detected systematically earlier by one of modalities. Methods: Women with biopsy-verified were enrolled prospectively monitored combined CE-CT every 9-12 wk evaluate first-line treatment. scans used clinical decision-making without accessing scans. At...

Abstract This study aimed to compare CE-CT and 2-[ 18 F]FDG-PET/CT for response monitoring metastatic breast cancer (MBC). The primary objective was predict progression-free disease-specific survival responders vs. non-responders on F]FDG-PET/CT. secondary assess agreement between categorization the two modalities. Treatment in women with MBC monitored prospectively by simultaneous F]FDG-PET/CT, allowing participants serve as their own controls. standardized evaluation criteria solid tumors...

Delineation accuracy of the gross tumor volume (GTV) in radiotherapy planning for head and neck (H&N) cancer is affected by computed tomography (CT) artifacts from metal implants which obscure identification as well organs at risk (OAR). This study investigates impact artifact reduction (MAR) H&N patients terms delineation consistency dose calculation precision radiation treatment planning.Tumor OAR delineations were evaluated CT scans eleven oropharynx with streaking region preceding...

Peritoneal carcinomatosis (PC) is a common endpoint in both gastrointestinal and non-gastrointestinal cancers, PC treated as other systemic metastases - unfortunately with disappointing results considerable side-effects. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) new method of applying traditional chemotherapy, preliminary data indicate that PIPAC safe, able to stabilize or improve quality life, can induce an objectively measurable reduction disease burden PC.PIPAC-OPC2...

A significant part of patients with head and neck squamous cell carcinoma (HNSCC) develop recurrent disease after curative radiotherapy. We aimed to analyze loco-regional recurrence pattern by identifying possible points origin three different methods in relation treatment volumes.A total 455 completed IMRT-based for HNSCC from 2006 2012. 159 had remaining cancer IMRT, developed or distant during follow-up. Among those, 69 recurrences affirmative CT PET/CT scan. Possible (POs) the were...

Abstract Background [ 18 F]-fluorodeoxyglucose-positron emission tomography/computed tomography ([ F]FDG-PET/CT) has been implemented sporadically in hospital settings as the standard of care examination for recurrent breast cancer. We aimed to explore clinical impact implementing F]FDG-PET/CT patients with clinically suspected cancer and validate diagnostic accuracy.

The purpose of this study was to examine whether staging with 18F-FDG PET/CT better predicts survival in patients recurrent head and neck squamous cell carcinoma (HNSCC) than chest x-ray (CXR) plus MRI or CT (CCT) MRI. Methods: This a prospective cohort based on paired data. Consecutive histologically verified HNSCC recurrence were enrolled from September 2013 March 2016. All underwent CXR/MRI, CCT/MRI, the same day before biopsy. imaging studies masked interpretation by separate teams...

The aim of the study was to identify frequency asymptomatic brain metastases detected by computed tomography (CT) scans in patients with metastatic cutaneous melanoma referred first-line systemic treatment. Between 1995 and 2009, 697 Danish were screened a contrast-enhanced CT scan before start interleukin-2 (IL-2)-based immunotherapy. Among patients, 80 had (12%). Patients' characteristics did not differ significantly between groups without metastases. Patients received treatment...

Abstract We aimed to evaluate the etiologies of constipation in patients with anorectal malformations having a good prognosis for bowel control but high risk constipation. included twenty-five from Odense university hospital Denmark. Patients were subjected colon transit time examination and resolution manometry (HRAM). The median age was 18 (14–24) 48% (12/25) females. Fifty-two % (13/25) diagnosed Types malformation perineal fistula (9/25), rectovestibular (8/25), rectourethral bulbar...
