Minimally invasive intraoperative lymphatic mapping and sentinel node biopsy has become the standard approach for staging the regional lymph nodes for early-stage melanoma. The procedure requires close collaboration of surgeon, pathologist, and nuclear medicine physician. The strength of lymphatic mapping and sentinel node biopsy is its accuracy of detecting occult lymph node metastases. Revers...

OBJECTIVE In the previous report, to simplify the synthesis and labelling procedures and to improve the biological properties, we developed a novel mannose receptor-binding agent, technetium-99m human serum albumin (99mTc-MSA), for sentinel lymph node detection. This study is the first clinical trial designed to test the reliability and feasibility of sentinel node detection using this new radi...

Abstract Case Summary Melanoma of the abdominal wall is not uncommon, and sentinel lymph nodes are usually located in lymphatic drainage basins axilla or inguinal region. Less frequently, interval can be found along vessels between primary cancer nearest basin. We present case a 53-year-old female with silicone breast implants who underwent scar excision node biopsy for 1mm Breslow thickness su...

Introduction: Several radiotracers are being used for sentinel node mapping in patients with breast cancer. In the current study, we reported our experience with 99m-Tc Phytate for sentinel node mapping in Mashhad University of Medical Sciences. Methods: All breast cancer patients who underwent sentinel node mapping using 99m-Tc Phytate were included. All patients received intradermal peri-are...

BACKGROUND In oral squamous cell carcinoma (OSCC), cervical lymph node status is the most important prognostic factor. Compared to elective neck dissection, reduced morbidity and better quality of life was demonstrated for sentinel lymph node biopsy, which is controversial because of the reduced detection rate of sentinel lymph nodes in close proximity to the injection site (also known as the s...

BACKGROUND The concept of sentinel lymph node surgery is to determine whether the cancer has spread to the very first lymph node or sentinel node. If the sentinel node does not contain cancer, then there is a high likelihood that the cancer has not spread to other lymph nodes. The sentinel node technique has been proven to be effective in different types of cancer. In this study we want to dete...

UNLABELLED Preoperative injection of radiocolloid for axillary sentinel node biopsy in breast cancer is uncomfortable for patients. This study evaluated the reliability of radiocolloid injection as determined by sentinel node identification rate and positive sentinel node biopsy rate, after the patient has been anesthetized in the operating room as compared with preoperative injection. METHOD...

The presence of axillary nodal metastases has a significant impact on locoregional and systemic treatment decisions. Historically, all node-positive patients underwent complete axillary lymph node dissection; however, this paradigm has changed over the last 10 years. The use of sentinel lymph node dissection has expanded from its initial role as a surgical staging procedure in clinically node-n...

AIMS AND BACKGROUND We studied the potential use of sentinel lymph node identification using a near-infrared fluorescence imaging technique in the treatment of cervical cancer. METHODS AND STUDY DESIGN Directly before the start of the operation, 0.2 ml of 5 mg/ml indocyanine green was prepared and injected into 4 sites in the cervix using a 26-gauge standard needle, at 3, 6, 9 and 12 o'clock ...
