Background: Ovarian cancer is the fifth most common cancer in woman and the fifth most frequent cause of cancer death. Ovarian cancers are usually asymptomatic until metastasized, patients have advanced disease at diagnosis in more than 2/3 of the cases. Totally 75-80 % of ovarian masses are benign. The strongest patient related risk factor for ovarian cancer is increasing age. The most ovarian...
Isozyme patterns of 23 different enzymes were compared in normal, benign, and malignant breast tissues; in MCF-7 cells; and in organoids of normal human breast tissue. Benign lesions generally showed isozyme patterns similar to those of normal tissues. Lactate dehydrogenase isozyme 5 was significantly increased in malignant tumors; MCF-7 cells had only lactate dehydrogenase (L-lactate:NAD oxido...
BACKGROUND Phyllodes tumors of the breast are rare fibroepithelial lesions, so relatively little is known about this disease entity. The present study was designed to identify differences in clinical features between benign borderline and malignant phyllodes tumors. MATERIALS AND METHODS Data from 246 women with phyllodes tumors of the breast treated in Cancer Hospital Chinese Academy of Medi...
Background & Aims: Early detection and reliable differentiation of benign and malignant liver tumors could lead to improved cure rate and costs. Ultrasound image (US) is a convenient medical imaging method for interpreting liver tumors. Visual inspection of ultrasound images sometimes is combined with error and needs biopsy to confirm whether a tumor would be benign or malignant. The aim of thi...
A suppression subtractive cDNA library representing mRNAs expressed at a higher level in the malignant human breast cancer cell line, MCF-7, relative to a benign breast tumor-derived cell line, Huma 123, contained a cDNA, M36, which was expressed in estrogen receptor alpha (ERalpha)-positive breast carcinoma cell lines but not in cell lines from normal/benign/ERalpha-negative malignant breast l...
Background & Aim: Breast carcinoma is the most common malignant tumor and the leading cause of death from carcinoma in women. Tumor grading is important as a prognostic factor in the treatment of patients and is routinely done on histologic specimens. Although breast cytology is a proven diagnostic technique in clinical practice, its use is frequently limited to establishing the benign or m...
Objective: One of the most significant cancers impacting health women is breast cancer. This study aimed to provide cancer classification (benign and malignant) using transfer learning method on ultrasound images.Methods: In present study, a public imaging dataset was used for classification. Transfer technique implemented detection or based images. The current research includes data 150 cases ...
For years, breast cancer has been a serious problem and malignant tumor case primarily causes death of women all around the world. In this paper, computer based analysis pathological classification system achieved some novelties are included to image processing methods, especially in segmentation base frequency distribution acquisition processed part. First, possible noises artifacts eliminated...
Aim: To identify the association of vascular endothelial growth factor (VEGF) immunoexpression in progression salivary gland tumor. Study design: Comparative cross-sectional study Place and duration study: Department Pathology, Peshawar Medical College. Duration was six months from date approval. Methodology: Forty five specimen tumor were studied which 30 benign 15 malignant. The endpoint asse...
Background and purpose : Malignant and infectious diseases are the most frequent causes of pleural effusion. Malignant diseases produce pleural effusion through different mechanisms: lymphatic and capillary obstruction, pneumonia or atelectasia. Therefore absence of tumor cells in aspirated effusion, highly declines the sensivity of the cytologic study. For this reason, the use of tumor marke...
