Clinical implications of human papillomavirus genotype in cervical adeno-adenosquamous carcinoma.

Background: Our aims were to evaluate the genotype distribution of human papillomavirus (HPV) and the correlation between HPV parameters and clinicopathological/treatment variables with prognosis in cervical adeno-adenosquamous carcinoma (AD/ASC).

Patients And Methods: Consecutive patients who received primary treatment for cervical AD/ASC International Federation of Gynecology and Obstetrics (FIGO) stages I-IV between 1993 and 2008 were retrospectively reviewed. Prognostic models were constructed and followed by internal validation with bootstrap resampling.

Long-term follow up of cervical cancer patients with unexplained squamous cell carcinoma antigen elevation after post-therapy surveillance using positron emission tomography.

Aim: We aimed to define the long-term follow-up results in cervical cancer patients with unexplained squamous cell carcinoma antigen (SCC-Ag) elevation (negative conventional imaging studies, computed tomography or magnetic resonance imaging) after definitive treatment using positron emission tomography (PET).

Methods: Of the 27 women with unexplained SCC-Ag elevation, 13 died or were alive with disease (12 PET true-positive, one PET false-negative) in our previous report. In this study, we reported long-term follow-up results for all the 14 patients remaining cancer-free at cut-off of our previous analysis (seven with true-negative PET and two with false-positive PET, and five with true-positive PET having received successful curative salvage therapy).

Whole-body biodistribution and radiation dosimetry of 18F-FP-(+)-DTBZ (18F-AV-133): a novel vesicular monoamine transporter 2 imaging agent.

Unlabelled: Vesicular monoamine transporter 2 (VMAT2) is highly expressed in the endocrine cells and brain. We investigated the biodistribution and radiation dosimetry of (2R,3R,11bR)-9-(3-(18)F-fluoropropoxy)-3-isobutyl-10-methoxy-2,3,4,6,7,11b-hexahydro-1H-pyrido[2,1-a]isoquinolin-2-ol ((18)F-FP-(+)-dihydrotetrabenazine [DTBZ] or (18)F-AV-133), a potential VMAT2 imaging agent showing encouraging results in humans, to facilitate its future clinical use.

Methods: Nine healthy human subjects (mean age +/- SD, 58.

Whole-body biodistribution and brain PET imaging with [18F]AV-45, a novel amyloid imaging agent--a pilot study.

Purpose: The compound (E)-4-(2-(6-(2-(2-(2-(18)F-fluoroethoxy)ethoxy)ethoxy) pyridin-3-yl)vinyl)-N-methylbenzenamine ([(18)F]AV-45) is a novel radiopharmaceutical capable of selectively binding to beta-amyloid (A beta) plaques. This pilot study reports the safety, biodistribution, and radiation dosimetry of [(18)F]AV-45 in human subjects.

Methods: In vitro autoradiography and fluorescent staining of postmortem brain tissue from patients with Alzheimer's disease (AD) and cognitively healthy subjects were performed to assess the specificity of the tracer.

(18)F-FDG PET in stage IB/IIB cervical adenocarcinoma/adenosquamous carcinoma.

Purpose: The diagnostic and prognostic value of (18)F-FDG PET in cervical adenocarcinoma/adenosquamous carcinoma (AC/ASC) is unclear. The aim of this study was to assess the value of PET in the management of cervical AC/ASC.

Methods: Patients with resectable FIGO stage IB/IIB cervical AC/ASC receiving a preoperative MRI scan and a PET or PET/CT scan before radical surgery were eligible.
