INTRODUCTION Thrombocytosis is present in a wide range of malignancies, with a reported incidence of 10% to 57%. Several reports have documented thrombocytosis at the time of diagnosis as a poor prognostic indicator. Our study is the first report evaluating the role of preoperative thrombocytosis and its association with survival in a predominantly African(More)
OBJECTIVE To update our report on the outcome of patients who underwent extended pelvic resection (EPR) for recurrent or persistent uterine and cervical malignancies. METHODS We reviewed the records of all patients who underwent EPR between 6/2000 and 07/2011. EPR was defined as an en-bloc resection of a pelvic tumor with sidewall muscle, bone, major(More)
Pelvic organ prolapse (POP) is a common, debilitating disorder affecting millions of women. Uterosacral ligaments (USLs) are the main supportive structures of the uterus and vagina and are often attenuated in women with POP. Although the mechanical strength of USLs is known to be dependent on collagen synthesis and catabolism and the degradation protein(More)
STUDY OBJECTIVE To assess the clinical outcomes and costs associated with robotic single-site (RSS) surgery compared with those of conventional laparoscopy (CL) in gynecology. DESIGN Retrospective case-control study (Canadian Task Force classification II-2). SETTING University-affiliated community hospital. PATIENTS Female patients undergoing RSS or(More)
OBJECTIVE Photodynamic therapy has the potential of a minimal invasive outpatient procedure for CIN patients at reproductive ages. The purpose of this study was to examine the pharmacokinetics and selectivity of porphyrin synthesis after topical application of hexaminolevulinate (HAL) in patients with cervical intraepithelial neoplasia (CIN). STUDY DESIGN(More)
OBJECTIVE In patients undergoing pelvic exenteration for recurrent gynecological malignancies, we assessed the performance of [(18)F]-FDG PET/CT for delineating disease extent and evaluated the association between quantitative FDG uptake metrics (SUVmax, total lesion glycolysis [TLG] and metabolic tumor volume [MTV]) and progression-free survival (PFS) and(More)
OBJECTIVE To describe the surgical technique, complications, and outcomes after anterior pelvic exenteration with total vaginectomy (AETV) for recurrent or persistent genitourinary malignancies. METHODS We reviewed the medical records of all patients who underwent AETV between 12/2002 and 07/2011. Relevant demographic, clinical, and pathological(More)
OBJECTIVE Magnetic resonance imaging (MRI) is the modality of choice for staging gynecological cancers owing to its superb soft tissue resolution, whereas F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) allows the assessment of glycolytic activity within the tumor microenvironment. In this study, we evaluated the incremental(More)
PURPOSE The use of multivariable clinical models to assess postoperative prognosis in ovarian cancer increased. All published models incorporate surgical debulking. However, postoperative CT can detect residual disease (CT-RD) in 40% of optimally resected patients. The aim of our study was to investigate the added value of incorporating CT-RD evaluation(More)
Macro- and microscopic aspects in the morphology of placenta after ozone therapy were studied in pregnant women with placental insufficiency and the results were compared with the control group. In the main group, the placentas were smaller and weighed less. After ozone therapy enlargement of terminal villi with true syncytiocapillary membranes was noted. A(More)
