Filter by:One-step Nucleic Acid Ampliļ¬cation assay (the OSNA assay) (Sysmex, Kobe, Japan) was an objective molecular technique that combines node tissue homogenization and subsequent reverse-transcription loop-mediated isothermal ampliļ¬cation of CK-19 mRNA in a single quick step. In the study, the performance of the OSNA assay was compared with the present standard histological evaluation, and a comparative analysis of OSNA assay with Touch Imprint Cytology (TIC) was also been made.
From May 2016 till May 2018 all breast cancer patients with operable disease submitted to surgery after neoadjuvant treatment would be divided in four groups considering initially clinical axillary stage, axillary procedure that was done, axillary response to preoperative systemic treatment and pathological axillary stage. In first postoperative year all patients will be monitored for appearance of locoregional and distant recurrence.
This clinical trial is designed as an observational study of 8-9 years of overall duration, but the first results and conclusions could be achieved in 3-4 years. In the first phase, which would last 3-4 years, the investigators will form three predetermined groups of breast cancer patients that would be monitored in the second phase for 5 postoperative years. All patients involved in this trial would undergo a defined protocol. All patients participating in this trial and all members of the investigation team would be completely introduced to the plan and aims of this trial. Two main hypotheses of this trial are that SLNB does not have a negative impact on clinical outcomes (locoregional recurrence and overall survival) in initially node-positive patients who achieved complete clinically axillary remission after neoadjuvant systemic treatment and that lymph node status after neoadjuvant treatment is a significantly more relevant prognostic factor than nodal status at the time of diagnosis. Therefore, the aim is to establish that sentinel lymph node biopsy, in node-positive breast cancer patients that achieve clinical remission after neoadjuvant treatment, is a reliable approach for surgical axillary management. Data would be collected individually for each patient and recorded on appropriate forms. After data completion, the principal investigator would import encoded data into the register. Data collected in this trial would be used for publications.
Evaluation of sensitivity of Sentinel lymph nodes for detecting nodal metastases in cervical cancer
Sentinel lymph node biopsy (SLNB) has become the standard procedure for staging of patients with clinically node-negative breast cancer. Breast-conserving surgery (BCS) has also been a standard treatment for patients with early breast cancer. However, approximately 10% of patients with BCS develop ipsilateral breast tumor recurrence (IBTR), and mastectomy or resection of the recurrent tumor is generally performed. There are no specific guidelines available regarding staging and treatment of the regional lymph nodes. However, the reported risk of axillary lymph node metastasis among patients with local recurrence after breast surgery and a previous negative sentinel node biopsy of 26 % is too high to be ignored. Moreover, evaluation of the regional lymph node basins might be helpful to decide on the indication for adjuvant radiotherapy and systemic treatment. For these reasons it seems sensible to perform a regional lymph node staging procedure in patients with locally recurrent breast cancer. In general practice, this would mean that patients with recurrent breast cancer and a previous negative sentinel node biopsy would receive an axillary lymph node dissection (ALND) and that patients with a previous ALND would receive no additional axillary staging. Lymphatic drainage after previous breast surgery and/or radiotherapy would be altered and it remains questionable whether SLNB at the time of surgery for IBTR (second SLNB) is technically feasible and ALND can safely be omitted. In this study, investigators propose for all patients the realization of SLNB procedure and systematically ALND whatever the results of SLNB analysis, only on patients previously treated with breast conservative surgery. The aim of this study is to evaluate on a homogeneous prospective multicentric cohort of patients the feasibility and the accuracy of a second SLNB procedure for IBTR.
This is a prospective, open label, multicenter, non-inferiority within-patient study to determine the effectiveness of IC2000 (Indocyanine Green (ICG) for Injection) and the SPY Portable Handheld Imaging System (SPY-PHI) as an intraoperative fluorescence visualization tool, in the visual identification of lymphatic vessels and lymph nodes (LNs) during lymphatic mapping and sentinel lymph node biopsy (SLNB) procedures as confirmed by Technitium99m (Tc99m) and Gamma Probe.
A randomized controlled double-blinded study comparing the intraoperative injection of lymphatic mapping agents Tc 99m tilmanocept to Tc 99m filtered sulfur colloid in breast cancer patients undergoing breast conservation and sentinel lymph node biopsy
The purpose of this study is to determine if there is a difference between the lymphatic drainage of the cervix and corpus of the uterus after injecting a radiocolloid in the cervix and blue dye in the corpus of the uterus and to investigate the identification rate of sentinel nodes using this technique in patients with cancer of the uterus.
The technique of sentinel lymph node mapping in patients with colon cancer varies among reports, and the optimal method remain to be established. The purpose of this study was to determine the optimal injection technique for sentinel lymph node mapping for colon cancer.
