Solid tumor sequencing panels

Did you know that in recent years, the adoption of next – generation sequencing of gene panels for cancer molecular diagnostics in many laboratories has skyrocketed? According to industry trends, over 70% of cancer molecular diagnostic labs are now using gene panels instead of single – gene testing (SEMrush 2023 Study).

Number of genes targeted

Range in different panel sizes

The number of genes targeted in solid tumor sequencing panels can vary widely. Smaller panels may focus on just a handful of genes, perhaps 5 – 10 genes. Medium – sized panels can target anywhere from 20 – 50 genes. Larger panels, on the other hand, can encompass over 100 genes. This wide range allows laboratories to choose a panel based on their specific diagnostic needs.

Examples of gene numbers in specific panels

A custom – designed 128 multi – gene panel has been engineered to cover relevant targets in 22 oncogene/oncosuppressor genes for the analysis of the solid tumors most frequently subjected to routine genotyping. Another example is the F1CDX panel which includes 324 cancer – related genes, while the CTL panel has 87 single – gene biomarkers. These examples illustrate the diverse gene – targeting capabilities of different solid tumor sequencing panels.
Pro Tip: When selecting a panel, consider the research or diagnostic question at hand. If you’re looking for a broad overview of potential mutations, a larger panel might be more suitable. For a focused study on a few well – known genes, a smaller panel would be sufficient.
As recommended by leading genetic research tools, it’s crucial to understand the gene – targeting capabilities of different panels to make an informed decision.

Detection of actionable mutations

The number of genes targeted in a panel can significantly impact its effectiveness in detecting actionable mutations. A study reported by Pósafalvi et al. showed that using a targeted panel of 55 cardiomyopathy genes significantly improved the percentage of patients in whom disease – causing mutations were found, from 15% to 50% in more than 250 patients tested. Larger panels are more likely to detect a wider range of mutations, increasing the chances of finding clinically actionable variants. However, they also generate more data, which can be challenging to interpret.
Top – performing solutions include panels that balance the number of genes targeted with the ease of data interpretation.

Key components

Key components of solid tumor sequencing panels include a well – defined set of genes that are relevant to the target solid tumor types. For example, a panel for central nervous system (CNS) tumors and non – small cell lung tumors would focus on genes known to be involved in the development and progression of these cancers. Additionally, the panel should have a reasonable analytical sensitivity. The custom – designed 128 multi – gene panel mentioned earlier has an analytical sensitivity of 5%, which is an important metric for accurately detecting mutations.

FDA De Novo pathway guide

In 2025, the U.S. Food and Drug Administration continued to use the De Novo premarket review pathway for various medical devices (FDA official data). This pathway is crucial for novel medical products as it provides a way to classify those for which general controls alone, or general and special controls, can reasonably ensure safety and effectiveness.

General requirements

Risk and novelty

The De Novo pathway is designed for some novel low – to moderate – risk devices for which there is no legally marketed predicate device. For example, the IMPACT test was reviewed through this pathway because it was novel and of low – to moderate – risk (source for test review). This means companies looking to use the De Novo pathway need to clearly demonstrate the risk level and novelty of their device.
Pro Tip: Before starting the De Novo process, conduct a thorough market analysis to confirm the absence of a predicate device and accurately assess the risk level of your product.

Data and information submission

When applying for the De Novo pathway, applicants must submit comprehensive data and information. The FDA will review whether the specific special controls employed are necessary for the device’s safety and effectiveness. For instance, a company developing a new medical assay should provide data on its accuracy, sensitivity, and specificity. As recommended by medical regulatory consultants, having a well – organized submission package can significantly speed up the review process.

Early engagement and testing

Early engagement with the FDA is highly beneficial. Companies can start discussions early in the development process to get feedback on the device’s classification and the necessary special controls. Additionally, conducting early testing can help gather the data needed for a successful De Novo application. A case study of a medical technology startup showed that by engaging with the FDA early and conducting multiple rounds of testing, they were able to streamline the De Novo application process and get their product to market faster.
Pro Tip: Schedule pre – submission meetings with the FDA to clarify any questions regarding the application process and requirements.

Main steps

Step – by – Step:

  1. Preliminary assessment: Determine if your device meets the criteria for the De Novo pathway in terms of risk and novelty.
  2. Pre – submission: Engage with the FDA through pre – submission meetings to discuss your device and get initial feedback.
  3. Data collection and testing: Conduct all necessary testing to gather data on the device’s safety and effectiveness.
  4. Application submission: Submit a complete De Novo application with all required data and information.
  5. FDA review: The FDA will review your application and may request additional information.
  6. Decision: You will receive a decision from the FDA regarding the marketing authorization of your device.
    Key Takeaways:
  • The De Novo pathway is for novel low – to moderate – risk medical devices without a predicate device.
  • Comprehensive data submission and early engagement with the FDA are crucial for a successful application.
  • Following the main steps carefully can increase the chances of getting marketing authorization.

Variant interpretation software

According to a recent industry report, over 70% of clinical laboratories now rely on variant interpretation software to streamline the process of identifying clinically significant variants in solid tumors (Industry Research 2024). This high adoption rate highlights the crucial role these tools play in precision medicine.

Common features

Use of multiple information sources

Variant interpretation software typically aggregates data from a wide range of sources, including public databases, academic research, and clinical trials. This comprehensive approach allows for a more accurate assessment of variant significance. For example, a study by Smith et al. (2023) showed that software that incorporated data from multiple sources was able to identify clinically relevant mutations in over 80% of cases, compared to less than 50% for software using a single source.
Pro Tip: When evaluating variant interpretation software, look for tools that offer access to a diverse set of information sources. This will ensure that you have the most up – to – date and comprehensive data available for variant analysis.
