radiotracer re-injection in case of sentinel node non-visualization in a breast cancer patient
نویسندگان
چکیده
we reported a 35 year old breast cancer patient who was referred to our nuclear medicine department for sentinel node mapping. she was planned to undergo mastectomy and lymphatic mapping. a dose of tc-99m phytate was injection in the peri-areolar region in an intra-dermal fashion. two hours post-injection no sentinel node was visible in the axilla. due to a high liver uptake, inadvertent intra-vascular injection was suspected and another dose of the radiotracer was injected in the breast. lymphoscintigraphy two minutes post-injection showed an axillary sentinel node. our case underscores the importance of second radiotracer injection in case of sentinel node non-visualization.

متن کاملInappropriate cervical injection of radiotracer for sentinel node mapping in a uterine cervix cancer patient: importance of lymphoscintigraphy and blue dye injection
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...
متن کاملSentinel Node Mapping in Non-small Cell Lung Cancer Using an Intraoperative Radiotracer Technique
Objective(s): Lymph node metastases are the most significant prognostic factor in localized non-small cell lung cancer (NSCLC). Identification of the first nodal drainage site (sentinel node) may improve detection of metastatic nodes. Extended surgeries, such as lobectomy or pneumonectomy with lymph node dissection, are among the therapeutic options of higher acceptab...
متن کاملFeasibility of sentinel lymph node mapping in renal cell carcinoma using intraoperative radiotracer injection
Introduction: The applicability of sentinel lymph node biopsy for early detection of metastasis in patients with renal cell carcinoma (RCC) is still in the validation phase and under investigation, which might be due to the unpredictability of the lymphatic pattern in RCC. In this study, we aimed to evaluate the feasibility and accuracy of sentinel node biopsy in patients with ...
متن کاملTime frame of sentinel node visualization in early breast cancer patients using intradermal injection of Tc-99m phytate: Imaging beyond 45 minutes does not yield more information
Introduction: One of the major problems of lymphoscintigraphy is the time of patient presence in the nuclear medicine wards. The operating room schedule can be compromised if the patients stay longer than usual in the nuclear medicine departments. However, too early imaging can be falsely negative for sentinel node visualization and delayed imaging may be required. The aim of t...
متن کاملSentinel lymph node in cervical cancer
Background: Cervical cancer is the second most common type of cancer among women. Effective screening programs can help cancer detection in early phases and reduce death. Metastasis to lymph nodes is one of the most prognostic factors in patients who underwent surgery. Also, a positive result from pathology report alert oncologist as a cause of death. Sentinel lymph node biopsy has been widely ...
