Background: The purpose of this study was to assess the dose distribution and coverage of level Ⅰ-Ⅱ axillary lymph nodes during whole breast tangential field radiotherapy (RT) after breast-conserving surgery in patients with breast cancer. Materials and Methods: The level Ⅰ-Ⅱ axillary lymph node volumes were retrospectively contoured by a single radiation oncologist based on computed tomography...

BACKGROUND Lymph node metastasis is commonly found in carcinoma of the thoracic oesophagus, even when the tumour invades only the submucosa. Although lymph node status greatly influences the outcome, the pattern of early lymphatic spread has not been investigated, and the role of lymph node dissection is still a matter of controversy. METHODS A series of 110 patients with superficial carcinom...

Background & Objective: The role of synchronized expression pattern of cytokeratin (CK) 7 and CK20 in the prognosis of colon adenocarcinoma is unclear. The current study aimed at determining the relationship between the expression of cytokeratins 7 and 20 and prognostic factors in colon adenocarcinoma. Methods: In the current cr...

Background:Lymph node metastasis is the most important prognostic factor in breast cancer patients. The present study was carried out to evaluate the association between ER, PR and HER-2/neu expression status, separately and in combinations with axillary lymph node involvement. Patients and methods: Two hundred and fifty eight breast cancer patients treated with modified radical mastectomy with...

BACKGROUND Lymph node involvement is one of the well-demonstrated prognostic factors in ampullary carcinoma. The aim of this study is to clarify the role of lymph nodes in predicting the survival outcome of ampullary carcinoma. METHODS A cohort of consecutive curative pancreaticoduodenectomies for ampullary carcinoma from 1999 to 2014 was retrospectively analyzed. The effect of node-associate...

AIM The study aimed to determine a prognostic value of primary tumor volume measured on the basis of integrated positron emission tomography-computerized tomography (PET-CT) in terms of mediastinal nodal metastases (N2) prediction in non-small-cell lung cancer (NSCLC) patients with PET-CT N2 negative lymph nodes. METHODS The records of 70 potentially operable NSCLC patients treated with surgi...

PURPOSE The chemokine receptors CCR7 and CXCR4 have been shown to play an important role in cancer metastasis. We therefore studied the differential expression of CCR7 and CXCR4, along with that of the biomarker HER2-neu, to evaluate whether these biomarkers could predict axillary lymph node metastasis in breast cancer. EXPERIMENTAL DESIGN Biomarker expression levels were evaluated using para...

background: molecular biomarkers are valuable in evaluation the course of malignancies. in this study, the relationship be­tween her2/neu, p53, steroid receptors and clinicopathological features of patients with breast cancer has been assessed. methods : three hundred thirty nine women with a primary diagnosis of breast cancer from 2001 to 2006 were included. they were evaluated for tumor featu...
