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…
The primary aim of the study is to assess whether DWI, DCE-MRI, T2*, and 18F-HX4-PET/CT predict overall survival in patients with pancreatic cancer treated with surgery and adjuvant chemotherapy or with neoadjuvant radiochemotherapy, surgery and…
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…
1. To determine the optimal acquisition technique for USPIO enhanced MRI (without contrast injection), DCE (without contrast injection) and DWI and T2* MRI of esophageal cancer in terms of signal-to-noise ratio, time resolution and spatial…
The aim of this study is to compare the image quality, diagnostic confidence and patient discomfort when using either positive (50 ml Télébrix Gastro + 950 ml water ) or negative 1000 ml water only in outpatients undergoing a contrast-enhanced…
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.
Predictive factors are needed to discriminate chemoradiotherapy responders from non-responders and to individualize the treatment regime. Various cytokines play a role in processes affecting tumour growth and metastasis. Furthermore, cytokines might…
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 purpose of this pilot study is twofold: - evaluation of the tumour movement and regression during and short after long course pre-operative therapy for locally advanced rectal cancer in order to develop an integrated or sequential dose…
The identify the health-related quality of life of elderly patients with resected stage III colon cancer and relate the outcomes to patient and treatment characteristics (surgery alone or surgery plus adjuvant chemotherapy). Furthermore, the impact…
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.
