Diffuse reflectance spectroscopy of human liver tumor specimens - towards a tissue differentiating optical biopsy needle using light emitting diodes

Abstract: Significant numbers of liver biopsies fail to yield representative tissue samples. This study was conducted to evaluate the ability of LED-based diffuse reflectance spectroscopy to discriminate tumors from liver parenchyma. Ex vivo spectra were acquired from malignant lesions and liver parenchyma of 32 patients who underwent liver resection using a white light source and several LEDs. Integrated spectra of two combined LEDs with emission peaks at 470 nm and 515 nm were classified with 98.4% sensitivity and 99.… Show more

“…Even after the use of the most promising technique still 20% of patients need to go under re-excision surgery, showing that this problem remains unsolved up to now. It seems that for overcoming this challenge emerging technologies need to result in higher diagnostic accuracy in a more cost and time-effective way [12][13][14][15].…”

“…Recently, researchers proved that Diffuse Reflectance Spectroscopy (DRS) has the potential to be used as a tumor margin assessment technique [12,13,[16][17][18][19][20][21][22][23][24][25]. Each tissue has its own special intrinsic light absorption and scattering for specific wavelengths which are known as "optical fingerprint".…”

“…73 Macroscopic methods such as reflectance spectroscopy to distinguish tumor from nontumor in needle biopsy samples are under development. 74 For CNBs, it is common even for superficial biopsies to obtain 2 or 3 cores, and for molecular studies, up to 10 passes may be required to obtain a 92% adequacy rate for lung biopsies using a 20-gauge side core needle. 75 Repeat CNBs, although uncommon, have similar adequacy rates to first biopsies.…”
