We used a multimodal nonlinear optics microscopy, specifically
two-photon excited fluorescence (TPEF), second and third harmonic
generation (SHG/THG) microscopies, to observe pathological conditions of
ovarian tissues obtained from human samples. We show that strong TPEF +
SHG + THG signals can be obtained in fixed samples stained with
hematoxylin and eosin (H&E) stored for a very long time, and that H&E
staining enhanced the THG signal. We then used the multimodal
TPEF-SHG-THG microscopies in a stored file of H&E stained samples of
human ovarian cancer to obtain complementary information about the
epithelium/stromal interface, such as the transformation of epithelium
surface (THG) and the overall fibrillary tissue architecture (SHG). This
multicontrast nonlinear optics microscopy is able to not only
differentiate between cancerous and healthy tissue, but can also
distinguish between normal, benign, borderline, and malignant specimens
according to their collagen disposition and compression levels within
the extracellular matrix. The dimensions of the layers of epithelia can
also be measured precisely and automatically. Our data demonstrate that
optical techniques can detect pathological changes associated with
ovarian cancer. (C) 2011 Society of Photo-Optical Instrumentation
