Background & objective: Breast cancer is the most common cancer in women. Lymph node involvement is the most important prognostic factor in this cancer. Since there is no consensus about the relationship between lymphocytic infiltration and breast cancer prognosis, this study was conducted to investigate the correlation between stromal lymphocytic reaction and lymph node involvement in grade 1 ...

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...

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 ...

Breast cancer is the most common site-specific cancer and is the second cause of mortality due to cancer in women. There are different prognostic factors including: axillary nodal status and tumor size(the most important factor), ER activity, PR, tumor grade and the type of histology. Other incompletely defined risk factors are: protease, catepstin, Her-2, etc. Her-2 is subtype 2 of E...

Introduction: HER-2 is a protein receptor of growth. Approximately 25% of breast cancers have overexpress HER-2. This study was designed to determine frequency of HER-2 overexpression in patients with breast cancer. Additionally, it intended to explore its relationship with some variables such as age, histopathologic diagnosis,tumor size, axillary lymph node involvement. Methods: This analyti...

background: sentinel lymph node biopsy (slnb) has replaced axillary lymph node dissection (alnd) in early breast cancer patients as the first line surgical approach to axillary nodes. further dissection is performed only when sln is involved by tumor cells. however, in a significant proportion of patients, non-sentinel nodes are still not involved and axillary dissection has no additional thera...
