OBJECTIVE To determine if there was a relationship between intrassellar pressure (ISP) and pituitary tumor volume. METHOD Between August 2002 and May 2004, 60 patients aged between 13 and 75 years old (39 males), having a pituitary adenoma were submitted to an endoscope transseptal approach. During the surgery and before tumor resection, 2 mm of the sellas floor were removed and a 1.5 mm dura...
Introduction: Prostatic specific antigen (PSA) is an excellent tumor marker, but it is not specific for prostate cancer. We evaluated the accuracy of PSA adjusted for transition zone volume calculated by transrectal ultrasonography in predicting prostate cancer in men compared with PSA density. Material and Methods: PSA adjusted for transition zone volume was obtained from 100 patients who u...
BACKGROUND/AIM In this study, we evaluated the dimensions and volume of rat mammary tumors and the association of these variables with tumor invasiveness. MATERIALS AND METHODS Tumors were measured by caliper and ultrasonography. Volume was determined by water displacement and by application of four formulas using tumor length (L), width (W) and depth (D) or tumor weight. RESULTS Results co...
The Prostate Health Index (PHI) has been used increasingly in the context of prostate cancer (PCa) diagnostics since 2010. Previous studies have shown an association between PHI and a tumor volume of >0.5 cm³. The aim of this study was to investigate the correlation between PHI and tumor volume as well as the Gleason score. A total of 196 selected patients with prostate cancer treated with radi...
Introduction: The decorin is a myokine that modulates the growth and the development of the cancer cells through the interaction with TGF-β. The present study is aimed to evaluate the protective effects of 8 weeks interval aerobic exercise on the expression of decorin and TGF-β, and tumor volume in a typical animal of breast tumor. Materials and Methods: In a exprimental research, forty adult f...
BACKGROUND The correlation between primary tumor volume and nasopharyngeal carcinoma (NPC) UICC 2002 T classification, N classification and distant metastasis after radiation therapy was discussed to provide further evidence for the inclusion of tumor volume into the TNM classification staging system. METHODS Between February 2001 and December 2008, 666 patients with NPC treated with intensit...
INTRODUCTION The differentiation of metastatic and primary brain tumors with certainty is important since clinical management and treatment of these two types of tumors are radically different. The purpose of the present study was to evaluate the effect of peritumoral edema volume, tumor volume and mass effect of tumor on differential diagnosis of metastatic and primary brain tumors. Also we ha...
BACKGROUND Tumor volume is an important predictor of outcome in radiotherapy alone. Its significance in concomitant chemoradiation (CCRT) is much less clear. We analyzed the prognostic value of primary tumor volume for advanced head and neck squamous cell carcinoma (HNSCC) treated with CCRT. METHODS Three hundred sixty patients treated with definitive CCRT for advanced HNSCC were selected. Th...
PURPOSE The purpose of this study was to evaluate whether predicted tumor volume could predict pathologic stage in patients undergoing radical prostatectomy. MATERIALS AND METHODS The clinical and pathologic data of 236 patients who underwent a 12-core needle biopsy followed by radical prostatectomy were obtained from our database and reviewed retrospectively. RESULTS Observed tumor volume ...
