Detailed Description

The Presence of lymph node metastases in cancer is a key factor for determining prognosis and forming an adequate treatment plan. Determining lymph node status, however, is a challenge. Ferumoxtran-10, an ultrasmall superparamagnetic iron oxide (USPIO) particle has proven to be a valuable contrast agent for detecting lymph node metastases using magnetic resonance imaging (MRI) in various types of cancer (also called nano-MRI). For small lymph node metastases (<5mm) the diagnostic accuracy of this technique does, however, drop substantially. Most of the studies that have been performed with these particles used a 1.5 Tesla or 3 Tesla MRI scanner. The investigators would like to increase the resolution of nano-MRI by using a 7 Tesla scanner, such that the investigators can increase the sensitivity of this technique for small lymph nodes. With this study the investigators would like to validate the results of this technique with pathology in rectal and breast cancer. In these cancer types many patients undergo a surgical lymph node dissection by bulk excision of tissue including the nodes, enabling a node-to-node comparison between MRI and pathology to validate our nano-MRI results . If successful this technique would form a non-invasive alternative to the current lymph node staging techniques such as surgery. Additionally (if metastatic nodes are present), it could complement image guided focal therapies on lymph node metastases such as radiotherapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Breast and rectal cancer
Subjects will receive intravenous dose of ferumoxtran-10. 24-36 hours later a 7 Tesla MRI scan will be performed, to detect lymph node metastases. In rectal cancer patients the mesorectum will be imaged and for breast cancer patients this will be performed in the ipsilateral axilla. Subjects will also undergo a 3 Tesla MRI scan as a comparison to the 7 Tesla MRI scan.
Drug: ferumoxtran-10
ferumoxtran-10 will be administered intravenously one day prior to the MRI scan
Device: 7 Tesla MRI
Subjects undergo a 7 Tesla MRI scan
Device: 3 Tesla MRI
Subjects undergo a 3 Tesla MRI scan

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Sensitivity and specificity of 7 Tesla MRI in combination with ferumoxtran-10 on nodal level.
Time Frame: within 2 weeks prior to the patients surgery
The images of the 7 Tesla MRI scan will be evaluated by a radiologist and every lymph node that is found will be scored as positive or negative. This will be compared to the pathological results to determine the sensitivity and specificity of ferumoxtran enhanced MRI on 7 Tesla for diagnosing whether a lymph node is metastatic or not.
within 2 weeks prior to the patients surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Comparison of 7 Tesla and 3 Tesla MRI
Time Frame: within 2 weeks prior to the patients surgery
The diagnostic accuracy (sensitivity and specificity as described in outcome 1) of 3 Tesla and 7 Tesla will be compared
within 2 weeks prior to the patients surgery
