The sentinel node is the first lymph node that receives the lymph drainage from the primary tumour. The pathological status of the sentinel node should reflect the histopathology of the entire regional lymph drainage area--both vulvar and cervical cancer spread through the lymphatic system. In gynaecological oncology recent studies have confirmed the utility of the sentinel node concept in vulv...

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 ability to reliably detect sentinel lymph nodes for sentinel lymph node biopsy and lymphadenectomy is important in clinical management of patients with metastatic cancers. However, the traditional sentinel lymph node mapping with visible dyes is limited by the penetration depth of light and fast clearance of the dyes. On the other hand, sentinel lymph node mapping with radionucleotide techn...

OBJECTIVE Sentinel lymph node frozen section is used to obviate the need for a second operation in breast cancer patients with involved nodes. However, the overall sensitivity, specificity and accuracy of sentinel lymph node frozen section are debated, and the impact of sentinel lymph node frozen section positivity on the risk of additional nodal metastases is not known and was the focus of thi...

UNLABELLED The technique of sentinel lymph node identification and biopsy has become a new popular technique for surgeon to improve staging of malignant diseases. It may also reduce the risk of complication related to standard lymphadenectomy. The method is still in experimental phase in case of esophageal cancer. A possible complication for employment of the method in this tumor is neoadjuvant...

The axillary lymph node status is the most reliable prognostic indicator of recurrence and overall survival in patients with breast cancer. The current standard surgical procedure for the management of invasive breast cancer is the complete removal of the cancer with total axillary clearance. However, recently, selective sentinel lymph node mapping and biopsy is gaining acceptance as a useful a...

INTRODUCTION The feasibility and accuracy of the sentinel lymph node biopsy for patients who have received neoadjuvant chemotherapy for the treatment of breast cancer is still controversial. MATERIAL AND METHODS Thirty-one consecutive patients with the diagnosis of invasive breast cancer who received neoadjuvant chemotherapy underwent sentinel lymph node biopsy and complete axillary lymph nod...

introduction: in the current study, we evaluated the feasibility of body outlining using tc-99m filled flood source for lymphoscintigraphy imaging. methods: 80 patients were included in the study. sentinel node mapping was done using tc-99m antimony sulfide colloid. for outlining the body a tc-99m filled flood source was used which was placed behind or lateral to the patients for anterior and ...

AIM To assess the axillary recurrence rate in operable breast cancer patients with clinically negative axilla after negative sentinel lymph node in whom axillary lymph node dissection had not been performed. METHODS Fifty consecutive female operable breast cancer patients with negative sentinel lymph node biopsy in whom axillary lymph node dissection had not been performed were included in th...

Sentinel lymph node mapping can help to direct surgical oncologic staging and metastatic disease detection in patients with complex lymphatic pathways. We hypothesized that indirect computed tomographic lymphography (ICTL) with a water-soluble iodinated contrast agent would successfully map lymphatic pathways of the iliosacral lymphatic center in dogs with anal sac gland carcinoma, providing a ...
