PURPOSE The role of step section and immunohistochemistry for diagnosing sentinel node micrometastases and the sentinel node concept in patients with prostate cancer was investigated. In patients administered neoadjuvant hormone therapy its influence on the sentinel node concept and metastasis diagnosis was also investigated. MATERIALS AND METHODS Of 62 patients without metastasis enrolled in...
BACKGROUND The impact of sentinel lymph node biopsy on breast cancer mimicking ductal carcinoma in situ (DCIS) is a matter of debate. METHODS We studied the rate of occurrence of sentinel lymph node metastasis in 255 breast cancer patients with pure DCIS showing no invasive components on routine pathological examination. We compared this to the rate of occurrence in 177 patients with predomin...
BACKGROUND Metastasis in the axillary lymph nodes is the most important known prognostic factor for breast cancer. We aimed to investigate the contribution of the radioisotope tracer method to the dye-only method by performing sentinel lymph node biopsy on the same patient group during a single surgical session. METHODS Forty-two patients who underwent operations in our clinic from February 2...
Lymphonodular metastases remain an important predictive and prognostic factor in gastric cancer development. The precise determination of the lymphonodular invasion stage can be made only by extended intraoperative lymphadenectomy and histopathological examination. But the main controversy is the usefulness of extended lymph dissection in early gastric cancer. This increases the duration of the...
UNLABELLED Minimally invasive sentinel node biopsy is associated with significantly less morbidity and has been evaluated in several studies in patients with gynecologic malignancies. Accurate identification of the sentinel lymph nodes is possible in most of the patients. Hybrid SPECT/CT is a newer modality which has been shown to improve the localization of the suspicious lesions and also prov...
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 ...
BACKGROUND To study the value of periareolar intra-dermal injection of Tc-99m sestamibi (MIBI) for sentinel node mapping in breast carcinoma. MATERIAL AND METHODS Fifty patients with early-stage breast cancer were included in our study. 17.5 MBq Tc-99m-MIBI was injected intradermally to 25 patients and the remainders were injected with the same dose of Tc-99m-antimony sulphide colloid. Anteri...
IMPORTANCE Recent data from clinical trials have challenged traditional thinking about axillary surgery in patients with breast cancer. OBJECTIVES To summarize evidence regarding the role of axillary interventions (surgical and nonsurgical) in breast cancer treatment and to review the association of these axillary interventions with recurrence of axillary node metastases, mortality, and morbi...
Sentinel lymph node biopsy in penile cancer: a comparative study using modified inguinal dissection.
INTRODUCTION In the case of clinically negative inguinal regions in penile cancer, the treatments proposed might vary from careful observation to radical dissection for all patients. We evaluated the effectiveness of the sentinel lymph node biopsy using lymphoscintigraphy in patients with penile cancer and at least one negative inguinal region. MATERIALS AND METHODS In 18 patients, biopsy of ...
