SPECT-CT Guided Lymphatic Mapping and Sentinel Lymphadenectomy (LM/SL) in Prostate Cancer
A study testing SPECT/CT guided LM/SL in people with Prostate Cancer, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 1 site in Canada.
Trial summary
Nodal staging is a key-step in pre-treatment assessment of prostate cancer. In patients with a low probability of nodal metastasis, bilateral pelvic lymphadenectomy is controversial. The large majority of them (> 80%) are free of nodal disease in obturator and external iliac stations. Read more about this study

About this study
Nodal staging is a key-step in pre-treatment assessment of prostate cancer. In patients with a low probability of nodal metastasis, bilateral pelvic lymphadenectomy is controversial. The large majority of them (> 80%) are free of nodal disease in obturator and external iliac stations. On the other hand, skip metastases located outside the standard lymphadenectomy may be missed, particularly in more proximal nodal stations (i.e. common iliac nodes and pre-sacral nodes).
In prostate cancer, growing data indicate the potential utility of LM/SL, particularly in patients with a low pre-test probability of nodal disease. However, very few data have been reported on the feasibility and the utility of SPECT/CT following LM/SL. In a pilot study including 11 patients with prostate cancer, Kizu and colleagues used a software image fusion from separate SPECT and CT studies. These authors concluded to the utility of image fusion to localize anatomically the SLNs. They also suggested the use of hardware fusion from a single gantry SPECT/CT device for accurate detection of SLNs. Accordingly, Corvin and colleagues recently reported the suitability of sentinel node detection in a series of 28 patients with prostate cancer; in this study, an integrated single slice SPECT/CT device was used to localize the SLNs.
In the light of the encouraging data from literature and our own preliminary clinical experience, we hypothesized that the use of integrated SPECT/low-dose multislice CT guided LM/SL may be of clinical interest in patients with prostate cancer.
Read the detailed description
A multidisciplinary team (urologist, oncologist, radiologist, pathologist, and nuclear medicine) will assess the technical feasibility of LM/SL with SPECT/CT as well as its clinical potential for the staging of regional lymph nodes in 30 consecutive patients with AJCC stages I-II-III prostate cancer scheduled for prostatectomy and pelvic lymph node dissection according to the standards of care.
This is a 2-day protocol with a single isotopic tracer (Tc99m-cysteine rhenium colloids, 10-15 nm). The tracer injections will be performed under trans-rectal ultra-sound guidance (1 inj/lobe, 74MBq, 0.2 cc).
The first day or injection day (D0), an early imaging session with planar acquisitions (anterior and posterior views) will be performed within 30 min post-tracer injection. A delayed imaging session with planar and SPECT/CT acquisitions will be also performed 1 to 3 hours after tracer injection. The SPECT/CT device to be used in this research protocol is the Infinia Hawkeye 4-slice from GE Healthcare. This hybrid camera incorporates a low-dose CT with a 2.5 mA current (eff.dose < 2mSv) on a dual-head gamma camera. SPECT/CT data will be analysed on the Xeleris 2.05v (Volumetrix for Hawkeye Oncology).
The second day (D+1 post-tracer injection), all prostate cancer patients will undergo a radical prostatectomy with complete pelvic lymph node dissection (CLND). Sentinel lymph nodes (SLNs) will be detected intra-operatively by using a gamma probe (Navigator, Tyco Healthcare). In this single tracer study, SLNs are defined as hot nodes only including the hottest node and any hot node ≥ 10% of the hottest node. In this SPECT/CT protocol, additional non-radioactive nodes eventually detected on the CT component and suspicious of tumor involvement (lymphadenopathies > 1cm) will be also removed, especially lymph nodes located in unpredictable lymphatic basins. Surgery will be performed by the same surgeons.
SLNs and non-SLNs will be analyzed by the same pathologist. For SLNs, a Hematoxylin \& Eosin staining (H-E) will be firstly performed. If negative, 3 more H-E stains levels will be performed and immuno-peroxidase stains for Cytokeratins AE1/AE3, PSA, and PAP. Non-SLNs will be analyzed according to the routine protocol with 3 H-E stained levels only. The SLN features will be noted: number, anatomical localization in vivo, counting rates ex vivo. The pathological characteristics of metastatic SLNs and non-SLNs will be precisely recorded: size, involvement (micro-metastases ≤ 2mm; macro-metastases; isolated tumor cells), % of nodes involved (small < 25%; moderate = 25-75%; massive > 75%).

Questions about this trial
What is this clinical trial studying?
A study testing SPECT/CT guided LM/SL in people with Prostate Cancer, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 5 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was stopped early (reason given: 1 patient has been enrolled. No complications reported. The research team decided to terminate the clinical trial due to insufficient patients' accrual.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Technical feasibility and clinical utility of LM/SL with SPECT/CT in patients with early stage prostate cancer versus CLND. (time frame: 1 year - 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00773318, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
