The Impact of Deep Neural Networks in Estimating Ki67 Expression for Breast Cancer Screening
In recent years, the prediction of tumor progression and chemotherapy response has become increasingly important in the field of cancer research. One promising avenue of investigation has been the utilization of Tumor Infiltrating Lymphocytes (TILs) and the nuclear protein Ki67 as prognostic factors. Both TILs and Ki67 expression have been shown to provide valuable insights into tumor behavior and patient outcomes.
Deep neural networks (DNNs) have emerged as powerful tools for analyzing complex datasets and have been able to achieve remarkable results in estimating Ki67 expression and determining intratumoral TILs scores in breast cancer cells. However, the rapid growth in the use of deep models has introduced a new challenge – the significant computational resources required to query and store these models.
In resource-limited contexts, such as IoT-based healthcare applications, the high computational costs associated with deep models present a major barrier. To address this issue, a team of researchers proposes a resource consumption-aware DNN for effectively estimating the percentage of Ki67-positive cells in breast cancer screenings.
Their approach has resulted in significant reductions in memory and disk space usage, with up to 75% and 89% reductions respectively. Additionally, energy consumption was reduced by up to 1.5 times while still maintaining or improving the overall accuracy of a benchmark state-of-the-art solution.
These positive results have encouraged further development and structuring of the adopted framework to allow for general-purpose usage. To support the adoption and use of this framework, a public software repository has been established.
This research represents an important step forward in addressing the resource limitations associated with deep models in healthcare applications. By reducing resource consumption while maintaining accuracy, this resource consumption-aware DNN can pave the way for wider implementation of deep learning techniques in the screening and diagnosis of breast cancer.
Future Implications
The development of this resource consumption-aware DNN concept has significant implications for the future of healthcare applications, particularly in the field of cancer research. By reducing the computational resources required for deep models, this approach can enable the deployment of advanced machine learning techniques in resource-limited settings, such as remote or low-resource areas.
In the context of breast cancer screening, the accurate estimation of Ki67 expression can play a crucial role in determining treatment plans and predicting patient outcomes. With the reduced resource consumption offered by this approach, healthcare personnel in diverse settings, including those with limited resources, can benefit from the insights provided by deep learning models.
Furthermore, the establishment of a public software repository to support the usage of this framework promotes collaboration and further development in the field. It allows researchers and practitioners to leverage the benefits of this resource consumption-aware DNN, contribute to its improvement, and adapt it for other applications beyond breast cancer screening.
Overall, this research represents a promising advancement in the optimization of deep neural networks for healthcare applications. By tackling resource limitations, we can unlock the full potential of deep learning techniques and enhance cancer diagnosis and treatment decision-making.
