Primary objective: To evaluate the in vivo biodistribution (measured in SUV) and quantitative radioactivity in organs of 89Zr-AMG211 in patients with relapse/refractory gastrointestinal adenocarcinoma as assessed by PET/CT. Secondary objectives: I)…
The aim of this present diagnostic study is to determine the accuracy by which we can detect residual disease after neoadjuvant chemoradiotherapy.
To evaluate the detection ctDNA in patients with PC of colorectal origin undergoing cytoreductive surgery and HIPEC at time of diagnosis in a feasibility trial This study is considered feasible:1. If in at least 70% of the patients ctDNA status…
Currently, only few publications exist which describe MRI for esophageal cancer. Therefore, the objective of the study is to develop a MRI protocol for imaging of this organ. The research will particularly be focussed on functional MRI. Those scans…
Part 1 1. Determine if accumulation of the fluorescent tracer bevacizumab-800CW can be detected for identification of pancreatic cancer tissue during surgery.2. Identify two doses of conjugate that provide the best visualization of tumor tissue…
To quantify motion based variation of the target volume of the primary tumor over the course of chemoradiotherapy in esophageal cancer patient, and to use this information to calculate appropriate PTV (planning target volume) margins according to…
To investigate the feasibility and utility of indocyanine green fluorescence imaging for intraoperative perfusion assessment in patients undergoing gastro-intestinal surgery, primarily measured by the number of intraoperative changes in operation…
1. Evaluate the feasibility of ESS for detection of field cancerization in BE patients. 2. Investigate the biological background of field cancerization by studying: a) (ultra)structural changes in the tissue and b) genetic abnormalities and clonal…
The primary objective of this study is to investigate the capability of diffusion weighted magnetic resonance imaging (DWI) to assess tumor resectability after FOLFIRINOX, compared to standard CT scan.
To investigate wether neo-adjuvant chemotherapy followed by cytoreductive syurgery and hyperthermic chemotherapy is feasible and reduces the number of irresectable patients with acceptable morbidity and mortality rates.
To compare the additional diagnostic yield obtained by using the PeerScope System* extended view vs. the diagnostic yield obtained by the Standard view colonoscopy.In addition, time measurements including time to cecum, time for withdrawal and…
The primary objectives are to determine the diagnostic performance of gadofosveset-enhanced T1-weighted MR imaging for the discrimination between pN0 and pN+ patients for both primary staging and restaging after chemoradiotherapy and to determine…
In patients undergoing surveillance endoscopy for Barrett's oesophagus or work-up and treatment for early neoplasia in Barrett's oesophagus we will evaluate the N-Vision pVLE system for the following items: 1) Correlating the VLE images…
To evaluate anatomical changes of tumor and organs at risk with MRI before and during radiation treatment.
The primary objective of this pilot intervention study is to determine the sensitivity of the fluorescent tracer bevacizumab-IRDye800CW using a flexible NIR fluorescence endoscope in identifying (pre)malignant esophageal lesions during endoscopy.…
To explore the role of 4D PET-CT in radiation treatment planning, relative to standard 3D PET-CT.
1. The primary aim of the proposed research is to compare the value of current best available imaging method (PET-CT) with recently evolved functional imaging with DWI-MRI alone or in combination with PET/CT in determining response to neo-adjuvant…
The objective of this explorative study is to assess the value of anatomical and functional magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography and computed tomography (PET-CT) in the evaluation of treatment…
The purpose of the study is to delineate the upstaging percentage of pN0 patients by detection of micrometastases (pN0micro+) and evaluate the benefits from adjuvant chemotherapy on disease recurrence in pN0micro+ CC patients.
1. to investigate the WavSTAT optical biopsy system by collecting fluorescence spectra of non-dysplastic and dysplastic Barrett mucosa and correlate these to the histology. The integrated optical/physical biopsy forceps will ensure spot-on…
