Artificial-intelligence-based end-to-end prediction of cancer immunotherapy response Call name: P 3 - SP 3.2 - Proiecte ERA.NET - COFUND

Abstract:

Cancer immunotherapy with immune checkpoint inhibitors (ICIs) is widely used in multiple cancer types, with proven benefits. However, response is not guaranteed, difficult to predict, and serious toxicity may occur. Predictive biomarkers for ICIs response exist, but only few of them are clinically used because they require tissue samples, are costly and increase turnaround time. Thus, there is an urgent clinical need to predict response to ICIs at patient’s

level.

Aims

TANGERINE partners have developed artificial intelligence (AI)-based histology image analysis and computed tomography (CT)-based radiomics for predicting immune features related to ICIs response. We propose to a) expand and combine them to develop and validate an end-to-end open AI tool to predict response and toxicity to ICIs; and b) identify cellular structures and image patterns associated with ICIs response that explain model predictions.

Methods

Digital images of tumour histopathology slides and CT scans will be retrieved, linked to clinical outcomes data and anonymized for analysis. An initial retrospective (2017-21) data retrieval from 1800 patients at 6 centres will continue with a prospective recruitment of 600 more to validate models. Patients that received ICls as first line for any tumour will be included and response recorded according to iRECIST. Radiomics and deep convolutional neural networks will be used. Model explainability will use spatial transcriptomics data on a subset of 30 patients. At analysis, homogenous subgroups will be considered, as gender and ethnicity.

Expected results and potential impact

TANGERINE will provide a public-available, non-invasive, low-cost tool based on routinely available images and clinical data to accurately predict ICI response and toxicity. The explanatory module might identify new patients on which ICI may be beneficial. The transnational collaboration will provide patients with enough variability to build generalizable

models.

Abstract:

The project is part of the CERN Atlas Tile Calorimeter Phase II Upgrade program and proposes the FPGA based firmware implementation for high voltage and temperature control of the PMT blocks using the HVOpto boards included in the Front-End electronics. This approach for high voltage regulation of the PMTs is known as the HV internal option of the Tile Calorimeter phase-II upgrade. The firmware is developed at the level of both Front-End and Back-End electronics. The Back-End electronics firmware continuously sends monitoring commands and also forwards the commands initiated by the DCS to the Front-End electronics. The aforementioned set of commands are used to set parameters for each PMT channel and also to read back PMT parameter values into the Back-End electronics. The proposed firmware description includes the data format, the VHDL wrappers with input-output ports and also the finite state machine used for the implementation of the desired functionalities.

Abstract:

In this project, a new active infrared (IR) methodology for product testing and quality control (e.g. breathing crack detection) in airspace inspection will be developed. The method is based on IR lock-in thermography technique coupled with laser scanning of the surface to be investigated. Crack depth prediction using finite element simulations and experimental approach will also be carried out. A proof-of-concept setup including mini-PC with embedded visualization toolbox that ensures the localization and the characterization of the defect on the examined sample in real time will be implemented. The method will be validated on real samples from aircraft industry (IAR Brasov, Romania).

Abstract:

Proiectul urmareste evaluarea fenotipului tumoral in cancerul mamar prin abordari de microfluidica si genomica functionala. Astfel, in cadrul acestei cercetari vor fi identificati noi markeri predictivi, de invazie si metastazare, respectiv markeri de evaluare a rezistentei la terapie, atat a componentei intrinseci cat si a celei dobandite in timpul tratamentului administrat. Daca scopul proiectului va fi atins, suntem increzatori ca datele noi legate de caracterizarea fenotipului tumoral, a capacitatii de invazie si metastazare a celuelor tumorale, respectiv a rezistentei lor la terapie vor juca in viitor un rol important în managementul tratamentului și stabilirea unei terapii personalizate. In acest fel, rezultatele obținute in cadrul acestui proiect ar putea duce la imbunatatirea tratamentului administrat pacienților cu cancer de sân.

Abstract:

The project is set to improve the ceramic material produced by CEMACON Zalau Company, by optimizing the existing technology of fabrication in order to reduce the energy demand in operation and implicitly the embodied energy in nZEBs.

The target is to improve both, the thermal characteristics and cost, by adding recycled materials and pore generating additives into the fabrication recipes. In the first stage, the basic raw materials that compose the ceramic masonry blocks will be analyzed from microstructural point of view. In the second stage, the microstructural, thermal and mechanical characteristics of some reference samples produced by CEMACON Company following the existing fabrication recipes will be defined. In the third stage the existing recipes will be optimized and the newly obtained products will be analyzed from thermal and physical-mechanical point of view. The improvement of quality control will be targeted by developing a methodology able to identify the structural deficiencies of the ceramic blocks through synchronous thermography detection. In the last stage, cost-benefit and environmental impact analyses will be performed, following the anti-seismic design regulations and the nZEB standards.

Abstract:

The main objective of the project is to improve the performance in dental diagnosis and to show that using different types of modulation sources (lasers, LEDs), modulation schemes, and complex image processing algorithms, one can construct high resolution images of defective zones of teeth.

The main investigation technique will be infrared lock-in thermography, which is a non-contact and non-invasive tool.

In order to evaluate the adaptation between restorative materials and tooth, an automatic defect detection methodology will be implemented.The method will allow the assessment of both marginal and internal microgaps located at the interface between tooth and filling. The progression of demineralization of enamel with time, for specimens undergoing different treatment demineralization periods, will also be analyzed. 2D maps of the demineralized zones of dental tissue and of the interfaces will be obtained, highlighting the areas with defects .

The method will be validated by complementary techniques: SEM and X-ray diffraction.

Regarding parallel processing of stained HL tissue images, considering the available resources for parallel computing and the existing Java implementations of the image processing pipeline, the selected software tools for parallel implementations of image processing algorithms were OpenCL. The stained HL tissue image pipeline together with the automatic cDNA microarray image processing pipeline are implemented using CUDA for multi-core architectures using OpenCL in order to decrease the computational time.

Abstract:

Automation is an open subject in DNA microarray image processing, aiming reliable gene expression estimation. The project presents a novel shock filter based approach for automatic microarray grid alignment. The proposed method brings up significantly reduced computational complexity compared to state of the art approaches, while similar results in terms of accuracy are achieved. Based on this approach, we also propose an FPGA based system for microarray image analysis that eliminates the shortcomings of existing software platforms: user intervention, increased computational time and cost. Our system includes application-specific architectures which involve algorithm parallelization, aiming fast and automated cDNA microarray image processing. The proposed automated image processing chain is implemented both on a general purpose processor and using the developed hardware architectures as co-processors in a FPGA based system. The comparative results included in the last section show that an important gain in terms of computational time is obtained using hardware based implementations.
