PURPOSE To evaluate low-dose non-enhanced CT (ldCT) and full-dose contrast-enhanced CT (ceCT) in integrated (18)F-fluorodeoxyglucose (FDG) PET/CT studies for restaging of uterine cancer. METHODS A group of 100 women who had undergone treatment for uterine cervical (n=55) or endometrial cancer (n=45) underwent a conventional PET/CT scans with ldCT, and(More)
PURPOSE To determine if the preoperative maximum standardized uptake value (SUVmax) measured by [(18)F]FDG PET/CT has prognostic value in patients with endometrial cancer. METHODS A total of 57 patients with FIGO stage I-IV endometrial cancer underwent FDG PET/CT imaging before radical surgery. SUVmax of the primary tumour was compared with histological(More)
Secreted frizzled related protein 1 (sFRP1) is a modulator of Wnt signaling. Recently, aberrations of Wnt signaling were reported to be involved in the pathology of various human neoplasms. We investigated the expression and function of sFRP1 in uterine leiomyomas. Secreted FRP1 expression was increased in leiomyomas, compared with normal myometrium using(More)
OBJECTIVE To determine whether contrast-enhanced PET/CT is more accurate than either non-enhanced PET/CT or enhanced CT alone for nodal staging of uterine cancer. METHODS Forty patients with endometrial cancer and cervical cancer underwent conventional PET/CT scan with low-dose CT (ldCT), followed by full-dose CT with IV contrast (ceCT) before radical(More)
OBJECTIVE To evaluate low-dose non-enhanced CT (ldCT) and full-dose contrast-enhanced CT (ceCT) in integrated 18F-fluorodeoxyglucose (FDG)-PET/CT studies for restaging of ovarian cancer. MATERIALS AND METHODS One hundred and twenty women who had undergone treatment for ovarian cancer underwent a conventional PET/CT scans with ldCT, and then ceCT. Two(More)
BACKGROUND AND AIM To evaluate the diagnostic value of integrated 18F-fluorodeoxyglucose (FDG) positron emission tomography and computed tomography (PET/CT) to discriminate malignant from benign ovarian tumors. METHODS One hundred and eight women suspected of having ovarian cancer underwent preoperative FDG-PET/CT scans. FDG uptake was quantified by(More)
OBJECTIVE The clinical usefulness of FDG-PET in the follow up of post-operative patients with endometrial cancer was retrospectively evaluated. METHODS Twenty-one post-operative patients with endometrial cancer received 30 FDG-PET examinations to evaluate recurrence or response to treatment. The findings of FDG-PET were compared with their serum levels of(More)
BACKGROUND The role of hMSH2 protein, one of the major DNA repair proteins, until now, had not been elucidated in terms of normal endometrial function during the menstrual cycle. The current study was designed to address this issue and to determine whether the expression of hMSH2 is altered in the course of endometrial carcinogenesis. METHODS(More)
It is difficult to treat cervical pregnancy without harming the intrauterine pregnancy. We report the case of a patient who was 37 years old and had an abdominal myomectomy. She had become pregnant by in vitro fertilization and egg transfer, and was transferred because of massive bleeding at 6 weeks of gestation. Afterwards, Escherichia coli infection was(More)
A new modulation classification method for M-ary QAM (MQAM) is proposed in this paper. Our method employs two dimensional decision variable composed of amplitude and cosine moments. Numerical results of the classification error probability show that the method presents superior classification performance for MQAM compared with amplitude moments or cosine(More)
