Ferrotran® in a dose of 0.13 mL/kg body weight of the reconstituted freeze-dried preparation (i.e. 2.6 mgFe/kg body weight). The recommended dose should be diluted in 100 mL of NaCl 9 mg/mL (0.9%) solution for injection/infusion prior to administration via the infusion filter as a slow intravenous infusion over 30 minutes (at a maximum rate of 4 mL/min).

Ferrotran® will be administered once to each patient. Histologically confirmed diagnosis and pre-operative staging are performed prior to the study as part of standard care. Surgery (RP with ePLND) and sampling of tissue specimens is performed after the Ferrotran®-enhanced MRI as part of standard care.

This will be a confirmatory, prospective, open-label, single-arm, reader-blinded, multi-centre phase 3 study to assess the diagnostic accuracy and safety of Ferrotran®-enhanced MRI in comparison to unenhanced MRI in the detection of pelvic lymph node metastases in newly-diagnosed adult patients with prostate cancer and an intermediate to high risk for lymph node metastases, based on the D'Amico criteria.

Potential patients for this study will be recruited by up to 10 centres specialised in prostate cancer. Study sites will be interdisciplinary, consisting of a uro-oncology sub-site, and a radiology sub-site with high-quality MRI, surgery and pathology. Study visits will be typically conducted at the recruiting sub-site, or as institutionally appropriate. Treatment visits for patients will be performed in the collaborating sub-site. Patients will be invited for study participation by the investigators in the context of specialised clinics. Interested patients will be provided with an information sheet and will undergo a detailed informed consent procedure prior to any study procedures. Recruitment will be continued until a sufficient number of patients have undergone Ferrotran® imaging and histopathological evaluation.

To compensate for an expected drop-out rate of 15% to 20%, recruitment will only be stopped as soon as at least 69 evaluable positive (patients positive) and at least 104 evaluable negative (patients negative) patients are available for analysis.

True positive fraction and false positive fraction of identified tumour tissue in pelvic lymph nodes will be analysed by histopathology as established reference method.

Patients with melanoma of the extremities included in the protocol. Preoperative, patients will receive two MRI-scans and a magnetic tracer injection at the primary tumor site. During surgery, SLNs will be detected using two types of magnetometers (SentiMag® \& DiffMag) in combination with Magtrace®, in addition to the standard procedure.

The sentinel lymph nodes (SLNs) are the first lymph nodes (LNs) to drain the tumor site and therefore the first LNs to bare metastases. Hence the importance to investigate these LNs for the best treatment strategy. Current-standard-of-care for melanoma patients with a melanoma stage of pT1b or higher, involve a surgical procedure, referred to as SLN biopsy (SLNB). The SLNB procedure involves a combined detection procedure using a radio-active tracer and blue dye followed by surgical dissection and evaluation of the LNs at the histopathology department. Due to the use of radioisotopes, this procedure suffers from several disadvantages such as limited availability, strict rules and regulations, degradation time in patient and radioactive load for user and patient.

To overcome the limitations of a radioactive tracer, a magnetic SLNB was developed which is facilitated by super paramagnetic iron-oxide (SPIO) nanoparticles. This potentially offers numerous benefits making surgery planning more flexible: no exposure to radiation, easy accessibility of the tracer, long shelf life and long half time in the patient. However, the currently available magnetometer for intraoperative detection of SPIO-enhanced LNs is hampered by a relatively low detection depth, biological noise, and effects of surgical equipment. Therefore, surgeons need to switch to plastic or carbon equipment and the system needs to be balanced prior to each measurement, which increases the surgery time.

A new and effective way to localize SPIOs is differential magnetometry (DiffMag). This patented detection principle, developed by MD\&I group at University of Twente (UT), utilizes the nonlinear magnetic response of nanoparticles. An additional advantage of SPIOs is their visibility on MRI, which could provide mapping the SLNs preoperatively. Especially in patients with melanomas on the abdomen or back this would be very useful to see which lymph node stations are connected to the melanoma. In addition, studies have shown that SPIOs are absorbed into lymph nodes in different ways, depending on the presence of metastases. SPIO-enhanced MR lymphography could therefore provide an opportunity for a non-invasive preoperative assessment of nodal status.

In this pilot study the investigators want to evaluate the clinical use of the DiffMag handheld probe. Moreover, the investigators want to map the lymph nodes (metastases) preoperatively using MR lymphography.
