Fluorescein angiography for the detection of metastases of ovarian tumor in the abdominal cavity, a feasibility pilot.

Background And Objectives: The growth and progression of ovarian tumor metastases at the peritoneal surfaces of the abdominal cavity are coupled with neovascularization. Newly formed tumor vessels show a more diffuse pattern and are more permeable for macromolecules than normal vessels. We investigated the possibility to detect (small) ovarian metastases in the abdominal cavity by means of fluorescein angiography.

Pharmacokinetics and pharmacodynamics of cisplatin after intraoperative hyperthermic intraperitoneal chemoperfusion (HIPEC).

Background: HIPEC is a new treatment modality for abdominal cancers that combines cytoreductive surgery with Hyperthermic, Intraoperative Peritoneal Chemotherapy, followed by systemic chemotherapy. A significant survival benefit has been shown for HIPEC compared with systemic therapy alone. However, it is not clear what is the contribution of i.

Antibodies against human papillomavirus type 16 and 18 E6 and E7 proteins in cervicovaginal washings and serum of patients with cervical neoplasia.

Serum antibodies against the E6 and E7 proteins of human papillomavirus (HPV) 16 and 18 are associated with cervical cancer. The aim of this study was to investigate the presence of local antibodies against HPV in cervicovaginal washings (CWs). In this study antibodies against the native HPV16 and HPV18 E6/E7 proteins were detectable in CWs (48%) and sera (29%) from patients with cervical cancer (n = 21) utilizing a sandwich protein enzyme-linked immunosorbent assay (ELISA).

A mathematical evaluation of dose-dependent PpIX fluorescence kinetics in vivo.

The in vivo pharmacokinetics of protoporphyrin IX (PpIX) after administration of 5-aminolevulinic acid (ALA) cannot be described accurately by mathematical models using first-order rate processes. We have replaced first-order reaction rates by dose-dependent (Michaelis-Menten [MM]) reaction rates in a mathematical compartment model. Different combinations of first-order and dose-dependent reaction rates were evaluated to see which one would improve the goodness-of-fit to experimentally determined in vivo PpIX fluorescence kinetics as a function of concentration.
