background: sentinel node biopsy (slnb) is the standard of care for breast cancer treatment and it is getting wide acceptance in iran. the radiation safety of the procedure has been investigated under controlled conditions, but the standard dose of radiotracer and techniques are not always observed in the community setting. the aim of this study was to assess the magnitude of the absorbed doses...
BACKGROUND We investigated the presence and distribution of the sentinel and the non-sentinel node micrometastases using complete serial sectioning and immunohistochemical staining (IHC), to inspect whether lymph node micrometastases spread to the sentinel lymph nodes first. METHODS A total of 35 patients, who underwent gastrectomy with a sentinel lymph node biopsy for gastric cancer, were en...
BACKGROUND In patients with clinically node-negative breast cancer, diagnosed with palpation and several types of imaging examination, sentinel lymph nodes accurately predict the status of the other axillary nodes, which determine the nature of subsequent adjuvant treatment. In addition, compared with axillary lymph node dissection, sentinel-node biopsy results in less postoperative morbidity, ...
OBJECTIVE To establish the prognostic value of knowledge of sentinel node status in melanoma. DESIGN Single centre prospective observational study, with sentinel nodes identified by lymphoscintigraphy, gamma probe, and intraoperative blue dye and examined by both conventional histopathology and immunopathology. SETTING Specialist surgical service in west of Scotland. PARTICIPANTS 482 pati...
UNLABELLED Laparoscopic evaluation of sentinel nodes is useful for staging prostate cancer, but preoperative localization of deep abdominal sentinel nodes with planar lymphoscintigraphy is difficult. We evaluated the value of SPECT/CT for detecting and localizing sentinel nodes in prostate cancer. METHODS (99m)Tc-nanocolloid was injected peri- and intratumorally, guided by transrectal ultraso...
OBJECTIVE Sentinel lymph node biopsy is the recommended approach in the evaluation of axilla during breast cancer surgery. In this study, results of patients who underwent methylene blue sentinel lymph node biopsy were evaluated. MATERIALS AND METHODS The study included 32 female patients with T1 and T2 tumors. 5 ml of 1% methylene blue was injected into the peritumoral area or around the cav...
AIMS To compare the performance of the Sentinel blood culture system with two other systems for the recovery of streptococci and anaerobes. METHODS Blood cultures were taken from 55 patients one to two minutes after dental extraction. The samples were tested by the radiometric Bactec 460; the Isolator 10, which works by lysis centrifugation; and Sentinel, a fully automated system, which detec...
Herein, we report a case of sentinel lymph node mapping in a uterine cervix cancer patient, referring to the nuclear medicine department of our institute. Lymphoscintigraphy images showed inappropriate intra-cervical injection of radiotracer. Blue dye technique was applied for sentinel lymph node mapping, using intra-cervical injection of methylene blue. Two blue/cold sentinel lymph nodes, with...
AIMS AND BACKGROUND Sentinel lymph node biopsy has been accepted as a standard procedure for early stage breast cancer. In this retrospective analysis, the results obtained with different methodological approaches using radiocolloid with or without blue dye were examined. METHODS A total of 158 sentinel lymph node biopsies were performed in 152 patients. Group A (85 patients) underwent lympha...
BACKGROUND We reviewed the available literature on the accuracy of sentinel node mapping in the lymph nodal staging of uterine cervical cancers. METHODS MEDLINE and Scopus were searched by using "sentinel AND (cervix OR cervical)" as key words. Studies evaluating the accuracy of sentinel node mapping in the lymph nodal staging of uterine cervical cancers were included if enough data could be ...
