Label-free multimodal nonlinear optical imaging of needle biopsy cores for intraoperative cancer diagnosis

Significance: Needle biopsy (NB) procedures are important for the initial diagnosis of many types of cancer. However, the possibility of NB specimens being unable to provide diagnostic information, (i.e., non-diagnostic sampling) and the time-consuming histological evaluation process can cause delays in diagnoses that affect patient care. Aim: We aim to demonstrate the advantages of this label-free multimodal nonlinear optical imaging (NLOI) technique as a non-destructive point-of-procedure evaluation method for NB tissue cores, for the visualization and characterization of the tissue microenvironment. Approach: A portable, label-free, multimodal NLOI system combined second-harmonic generation (SHG) and third-harmonic generation and two- and three-photon autofluorescence (2PF, 3PF) microscopy. It was used for intraoperative imaging of fresh NB tissue cores acquired during canine cancer surgeries, which involved liver, lung, and mammary tumors as well as soft-tissue sarcoma; in total, eight canine patients were recruited. An added tissue culture chamber enabled the use of this NLOI system for longitudinal imaging of fresh NB tissue cores taken from an induced rat mammary tumor and healthy mouse livers. Results: The intraoperative NLOI system was used to assess fresh canine NB specimens during veterinary cancer surgeries. Histology-like morphological features were visualized by the combination of four NLOI modalities at the point-of-procedure. The NLOI results provided quantitative information on the tissue microenvironment such as the collagen fiber orientation using Fourier-domain SHG analysis and metabolic profiling by optical redox ratio (ORR) defined by 2PF/(2PF + 3PF). The analyses showed that the canine mammary tumor had more randomly oriented collagen fibers compared to the tumor margin, and hepatocarcinoma had a wider distribution of ORR with a lower mean value compared to the liver fibrosis and the normal-appearing liver. Moreover, the loss of metabolic information during tissue degradation of fresh murine NB specimens was shown by overall intensity decreases in all channels and an increase of mean ORR from 0.94 (standard deviation 0.099) to 0.97 (standard deviation 0.077) during 1-h longitudinal imaging of a rat mammary tumor NB specimen. The tissue response to staurosporine (STS), an apoptotic inducer, from fresh murine liver NB specimens was also observed. The mean ORR decreased from 0.86 to 0.74 in the first 40 min and then increased to 0.8 during the rest of the hour of imaging, compared to the imaging results without the addition of STS, which showed a continuous increase of ORR from 0.72 to 0.75. Conclusions: A label-free, multimodal NLOI platform reveals microstructural and metabolic information of the fresh NB cores during intraoperative cancer imaging. This system has been demonstrated on animal models to show its potential to provide a more comprehensive histological assessment and a better understanding of the unperturbed tumor microenvironment. Considering tissue degradation, or loss of viability upon fixation, this intraoperative NLOI system has the advantage of immediate assessment of freshly excised tissue specimens at the point of procedure.

Read Abstract +

Optical Coherence Tomography (OCT) is a new, non-invasive diagnostic technique for high resolution optical 3D imaging, which was developed and applied to several different biological materials during the lasi; five years [1, 2, 3]. A unique application ofthis technique is the microscopical cross-sectional imaging ofpostenor structures ofthe eye which are not accessable with other high resolution techniques in-vivo neither with x-ray-imaging nor with high frequency ultrasound scanning. The superior spatial resolution on the order ofabout lOtm laterally and axially, the high signal-to-noise ratio ofmore than 100 db and the fast acquisition-time of one second for a two dimensional scan provides a technique for cross-sectional in-vivo-momtoring ofintraocular structures and therefore the possibility to study the time course of anatomical and pathological developments in the eye. The acute morphological changes of ocular structures and their biological healing response after shortterm impacts such as high-intensity laser exposures are ofparticular interest for the understanding of the mechanisms responsible for therapeutic laser-application in ophthal-mology as well as for laser injury to the eye. A correlation between cross-sectional OCT-images and structural findings using classical histopathological techniques facilitates a better interpretation ofthe characteristic patterns seen in OCTimages and defines the sensitivity ofthe OCT-technique to image morphological details. On the other hand preparational artefacts not avoidable in all histological procedures can be identified and analyzed by comparing histological micrographs with OCT-images of exactly the same structure. First results of an experimental study where retinal effects were produced in monkey eyes using laser pulses from 200 ms to 130 fs in duration are presented in this article. The applied energies from 5tJ to 50 mJ were able to induce the whole spectrum of biological effects possible in the eye, ranging from intraretinal microruptures to extensive thermal denaturation and massive preretinal hemorrhages [4, 5, 6].
