The role of PET/CT with fluorine-18-deoxyglucose in the detection of relapsed serous ovarian cancer in patients with normal serum CA125 levels.

Objectives: To assess the role of the positron emission tomography with fluorine-18-deoxyglucose (PET/CT) in the detection of recurrent serous ovarian cancer in patients with normal serum CA125 level.

Material And Methods: Thirty-one patients with suspected recurrent serous ovarian cancer with normal (< 35 IU/mL) serum CA125 level and no prior recurrence underwent PET/CT imaging. The results of the PET/CT were analyzed considering clinical data of the patients, histological diagnosis and 6 months follow-up.

The value of [18F]FDG PET/CT examination in the detection and differentiation of recurrent ovarian cancer.

Background: The exact role of positron emission tomography with fluorine-18-deoxyglucose ([18F]FDG PET/CT) in an early diagnosis of relapsed ovarian cancer is not clearly defined. The aim of the study was to assess the value of [18F]FDG PET/CT in the detection and differentiation of recurrent ovarian cancer.

Material And Methods: Eighty-four patients with suspected recurrent ovarian cancer underwent [18F]FDG PET/CT examination.

The number of CD163 positive macrophages is associatedwith more advanced skin melanomas, microvessels density and patient prognosis.

The study was aimed to evaluate the number of TAMs and to investigate whether they have association with microvessels density and patients' survival times. 46 cases of melanomas, divided into four groups according to the Breslow scale, were tested immunohistochemically with antibodies anti-CD68, CD163, iNOS to vizualized macrophages and anti-CD34 antibody to stain microvessels. The number of macrophages and the microvessels density were counted by hotspot analysis using an image analysis system.
