Item type:Publication, Decoupling channel count from field of view and spatial resolution in single-sensor imaging systems for fluorescence image-guided surgery(SPIE-Intl Soc Optical Eng, 2022-09-26) ;Blair, Steven ;Garcia, Missael ;Zhu, Zhongmin ;Liang, ZuodongLew, BenjaminNear-infrared fluorescence image-guided surgery is often thought of as a spectral imaging problem where the channel count is the critical parameter, but it should also be thought of as a multiscale imaging problem where the field of view and spatial resolution are similarly important. Aim Conventional imaging systems based on division-of-focal-plane architectures suffer from a strict relationship between the channel count on one hand and the field of view and spatial resolution on the other, but bioinspired imaging systems that combine stacked photodiode image sensors and long-pass/short-pass filter arrays offer a weaker tradeoff. Approach In this paper, we explore how the relevant changes to the image sensor and associated image processing routines affect image fidelity during image-guided surgeries for tumor removal in an animal model of breast cancer and nodal mapping in women with breast cancer. Results We demonstrate that a transition from a conventional imaging system to a bioinspired one, along with optimization of the image processing routines, yields improvements in multiple measures of spectral and textural rendition relevant to surgical decision-making. Conclusions These results call for a critical examination of the devices and algorithms that underpin image-guided surgery to ensure that surgeons receive high-quality guidance and patients receive high-quality outcomes as these technologies enter clinical practice. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Recommmendations for the diagnostic algorithm in lung cancer. Consensus statement of the Macedonian respiratory society and the Macedonian association of pathology(Македонско лекарско друштво = Macedonian Medical Association, 2019); ;Todevski Dejan ;Rexhepi Arben ;Tatabitovska AleksandraLung cancer is the “number one cancer killer” in the world. Its prevalence is associated to smoking as the primary cause, although air pollution in general and genetic factors are also in stake. The mortality especially from advanced stage lung cancer is still high, although there has been a significant improvement in the past 10 years, mostly due to the introduction of novel compounds such as targeted and immunological treatment. The advances in the treatment of NSCLC have imposed updating of the guidelines for the diagnostic procedure and screening of LC, for the indications for molecular testing as well as for targeted selection of patients who shall benefit the most of the novel treatment modalities. These recommendations shall fulfill their purpose only if implemented in the educational curriculum and if incorporated in the healthcare system strategies. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Standardization and optimization of fluorescence in situ hybridization (FISH) for HER-2 assessment in breast cancer: A single center experience(Association of Basic Medical Sciences of FBIH, 2018-05-20); ; ; ; <jats:p>Accurate assessment of human epidermal growth factor receptor 2 (HER-2) is crucial in selecting patients for targeted therapy. Commonly used methods for HER-2 testing are immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). Here we presented the implementation, optimization and standardization of two FISH protocols using breast cancer samples and assessed the impact of pre-analytical and analytical factors on HER-2 testing. Formalin fixed paraffin embedded (FFPE) tissue samples from 70 breast cancer patients were tested for HER-2 using PathVysion™ HER-2 DNA Probe Kit and two different paraffin pretreatment kits, Vysis/Abbott Paraffin Pretreatment Reagent Kit (40 samples) and DAKO Histology FISH Accessory Kit (30 samples). The concordance between FISH and IHC results was determined. Pre-analytical and analytical factors (i.e., fixation, baking, digestion, and post-hybridization washing) affected the efficiency and quality of hybridization. The overall hybridization success in our study was 98.6% (69/70); the failure rate was 1.4%. The DAKO pretreatment kit was more time-efficient and resulted in more uniform signals that were easier to interpret, compared to the Vysis/Abbott kit. The overall concordance between IHC and FISH was 84.06%, kappa coefficient 0.5976 (p < 0.0001). The greatest discordance (82%) between IHC and FISH was observed in IHC 2+ group. A standardized FISH protocol for HER-2 assessment, with high hybridization efficiency, is necessary due to variability in tissue processing and individual tissue characteristics. Differences in the pre-analytical and analytical steps can affect the hybridization quality and efficiency. The use of DAKO pretreatment kit is time-saving and cost-effective.</jats:p> - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Multispectral imaging sensors for detecting UV endogenous and NIR exogenous fluorophores(SPIE Digital Library, 2024-03-13) ;Gruev V ;Zhu Z ;Jin Y ;Hajek BLymph node mapping is a routine procedure during numerous cancer surgeries, yet the intraoperative identification of affected lymph nodes remains a clinical challenge. In response to this, we've introduced a multispectral camera that covers the UV, visible, and NIR spectrum. This innovative device facilitates lymph node imaging using both endogenious UV fluorescence and exogenious introduced NIR fluorescence, aiding in pinpointing the affected nodes. This presentation will showcase relevant clinical findings. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Identification of Sentinel Lymph Node in Breast Cancer with three Tracers (Radiocolloid, Methylene blue, and Indocyanine Green). (Case Report)(Scientific foundation SPIROSKI, 2020-09-10); ;Viktor Gruev; ; BACKGROUND: Sentinel lymph node (SNL) biopsy in breast cancer for the determination of axillary status is standard procedures in surgical treatment of early-stage breast cancer. The identification of the SNL is usually performed by radiocolloid injection or/and injection of methylene blue due. The use of indocyanine green (ICG) dye, which is fluorescent dye, which movement in breast and axillar pit, can be followed with special cameras which detect near infrared specatar of light. CASE REPORT: In this paper, we present case report of patient with breast cancer, where we perform SNL detection with three methods: Use of radiocolloid which we trace with static gamma camera, and intraoperatively with hand held gamma probe, methylene blue dye which movement we followed by eye contact and using indocyanine green which movement was followed by specially constructed multispectral camera, which can detect near-infrared fluorescence that is emitted by ICG and methyline blue, respectively. CONCLUSION: Fluorescent imaging with ICG is a sensitive, valuable, and safe method for SNL biopsy. Finding new agents that would identify the SNL, especially if they are not radioactive would be an important step in wider application of this method. - Some of the metrics are blocked by yourconsent settings
