Despite progress in breast cancer treatment, disparity persists in survival time between African American (AA) and Caucasian women in the US. Tumor stage and tumor grade are the major prognostic factors that define tumor aggressiveness and contribute to racial disparity between AA and Caucasian women. Studying the interaction of race with tumor grade or stage may provide further insights into t...
Background: Certain marker studies have practical importance in the biology of prostate cancer. The purpose of this study was to determine whether the quantification of certain neuroendocrine and proliferative markers obtained during transurethral resection or prostatectomy, would help in the prognostic evaluation of prostatic adenocarcinomas. Methods: The present study was performed on samples...
background and objective: breast cancer is the commonest cancer of indian women. estrogen and progesterone expression is seen in benign breast lesions and in breast carcinoma associated with good prognostic parameters and it correlates well with response to hormone therapy. although a lot of studies have been conducted in the past on hormone receptor expression in breast cancer and few have cor...
UNLABELLED Dynamic contrast imaging techniques are considered the standard of care for the radiological diagnosis of hepatocellular carcinoma (HCC) in cirrhosis. However, the accuracy of radiological diagnosis depends largely on the degree of arterial hypervascularization, which increases with tumor size. Owing to the interplay and prognostic relevance of tumor vascularization and cell differen...
Malignant glioma comprises glioblastoma [World Health Organization (WHO) grade IV], anaplastic astrocytoma (WHO grade III), mixed anaplastic oligoastrocytoma (WHO grade III) and anaplastic oligodendroglioma (WHO grade III). Diagnosis after biopsy or tumor resection is made according to the revised WHO classification. Prognosis depends on tumor grade and histology. Glioblastoma carries the worst...
objective: the purpose of this pilot study was to determine whether the mri and biomarkers human epididymis protein 4 (he 4 ) and ca 125 correlate with depth of myometrial invasion, histologic grade, cervical involvement and nodal metastases in patients with endometrioid adenocarcinoma of the uterus. materials and methods: this was a prospective, observational study in women with biopsy-proven ...
Low-grade central osteosarcoma is a rare subtype of tumor with low-grade malignancy. Currently, wide resection with negative resection margin is the standard treatment for this disease. The role of neoadjuvant chemotherapy in low-grade central osteosarcoma was controversial and was mostly considered for tumors containing high-grade focal areas. Local tumor recurrences often exhibited a tumor wi...
OBJECTIVES The clinical management of meningioma is guided by tumor grade and biological behavior. Currently, the assessment of tumor grade follows surgical resection and histopathologic review. Reliable techniques for pre-operative determination of tumor grade may enhance clinical decision-making. METHODS A total of 175 meningioma patients (103 low-grade and 72 high-grade) with pre-operative...
BACKGROUND The functional diffusion map (fDM) has been suggested as a tool for early detection of tumor treatment efficacy. We aim to study 3 factors that could act as potential confounders in the fDM: areas of necrosis, tumor grade, and change in tumor size. METHODS Thirty-four pediatric patients with brain tumors were enrolled in a retrospective study, approved by the local ethics committee...
background and objective: histological grading has prognostic and therapeutic implications in meningioma. however, histological criteria are sometimes not fulfilled to predict the biological behavior of meningiomas. p63 gene is a novel p53 family member, known as tumor suppressor factor, with multiple isoforms and shows high expression in many normal and neoplastic human tissues. in this study,...
