Immune Marker Classification for SIRT Response Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for classifying cancer patients for treatment with selective internal radiation therapy (SIRT) lack accuracy in predicting response, leading to suboptimal treatment outcomes.
Innovation Solution
An in vitro method involving the measurement of immune marker expression in leukocyte samples to classify patients as sustained responders (SR) or transient/non-responders (TR/NR) to SIRT, using a processing unit to allocate probability scores based on immune marker profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current classification methods are used for SIRT treatment, then treatment can be provided to patients, but prediction accuracy of treatment response is low
Solution Approach 1:
The patent segments the patient population into distinct response categories (sustained responders, transient responders, non-responders) based on immune marker profiles. This segmentation enables precise prediction of treatment response by classifying patients into specific groups with characteristic immune signatures, directly improving measurement precision while maintaining manageable system complexity through defined classification criteria.
Solution Approach 2:
The patent utilizes changes in immune marker parameters (expression levels, ratios, combinations) to predict treatment response. By monitoring specific immune parameters before and after treatment, the system achieves high prediction accuracy without requiring complex diagnostic infrastructure, as these parameters can be measured using standard immunological assays.
2Measurement precision
If immune marker measurement is performed to classify patients, then prediction accuracy improves, but time and resources for analysis increase
Solution Approach 1:
The patent performs immune marker measurements and classifications before treatment initiation (pre-treatment baseline assessment). This preliminary action allows clinicians to identify sustained responders who are most likely to benefit from SIRT, enabling informed treatment decisions before committing resources, thereby reducing wasted time and resources on patients unlikely to respond.
Solution Approach 2:
The patent focuses measurements on specific, locally-defined immune markers and their relationships (ratios, combinations) rather than comprehensive immune profiling. This localized approach to quality measurement captures the essential predictive information needed for accurate classification while minimizing the time and resources required for analysis.
3Adaptability or versatility
If comprehensive immune marker profiling is used, then treatment personalization improves, but system complexity increases
Solution Approach 1:
The patent applies local quality by focusing on specific immune markers and their relationships rather than comprehensive immune system profiling. By measuring particular markers (and their ratios or combinations) that have demonstrated predictive value, the system achieves effective treatment personalization without the complexity of analyzing the entire immune repertoire.
Solution Approach 2:
The patent creates a universal classification framework that can be applied across different SIRT treatment contexts and patient populations. The immune marker-based classification system serves multiple functions: predicting response, guiding treatment decisions, and potentially monitoring treatment efficacy, thereby achieving high adaptability through a relatively simple, multi-functional assessment tool.

AI summary
A method for the prognosis of response to treatment for a patient suffering from cancer, the method comprising: measuring the expression of at least one immune marker in a leukocyte sample taken from the patient with cancer; classifying the patient sample into (i) sustainable responders (SR) to selective internal radiation therapy (SIRT) or (ii) transient/non-responders (TR/NR) to (SIRT) based on expression of the at least one immune marker in relation to a predetermined value and treating sustainable responders (SR) to SIRT or SIRT or a composition comprising SIRT and an immunotherapy. In a preferred embodiment, the method is for the prognosis of response to treatment of a Hepatocellular carcinoma (HCC) patient comprising detecting the co-expression of PD-1 or Tim-3 with CCR5; or expression of PD-1, Tim-3, CXCR6, or combinations thereof in a leukocyte sample taken from the patient.
