Its relative lethality is a result of multiple factors including its difficult diagnosis and rapid progression, resulting in only a <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60643-6/fulltext">15–25% 5-year survival rate</a>. Determining the extent of tumor growth (or T-stage) is a critical part of accurate diagnosis and treatment, but this information can be challenging to obtain for esophageal cancer, particularly at early stages.</p> <h2 style="font-size: 100%"><strong>Computed tomography angiography</strong></h2> <p>Clinically, doctors utilize a number of complex methods for tumor-stage determination, including computed tomography angiography (CTA). This procedure combines a typical CT scan with the injection of a dyeing agent that provides blood vessel and tissue contrast. While the procedure can be highly accurate for late-stage esophageal tumors, <a href="https://academic.oup.com/dote/article/31/1/dox113/4101232">it struggles to accurately identify early tumors</a> while also being invasive and cost-prohibitive. This leaves room for improved methods that can more accurately categorize these tumors earlier, enabling improved treatment.</p> <p>The increased prevalence of powerful 3D reconstruction software has provided a new avenue for tumor analysis. These tools can perform a range of data post-processing and segmentation to not only identify tissue structures more accurately, but also to analyze the resulting reconstructions for trends and identifying characteristics.</p> <div id="attachment_1465" style="width: 2058px" class="wp-caption aligncenter"><img decoding="async" aria-describedby="caption-attachment-1465" class="size-full wp-image-1465" src="https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-1_2048x850.jpg" alt="Esophageal cancer tumor progression at different T-stages, reconstructed with Amira Software" title="Esophageal cancer tumor progression at different T-stages, reconstructed with Amira Software" width="2048" height="845" srcset="https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-1_2048x850.jpg 2048w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-1_2048x850-300x124.jpg 300w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-1_2048x850-1024x423.jpg 1024w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-1_2048x850-768x317.jpg 768w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-1_2048x850-1536x634.jpg 1536w" sizes="(max-width: 2048px) 100vw, 2048px" /><p id="caption-attachment-1465" class="wp-caption-text">Esophageal tumor progression at different T-stages, reconstructed with Amira Software.

Data was collected from 155 patients with esophageal cancer at various T-stages, from T1 to T4. Utilizing the data segmentation and reconstruction capabilities of Amira Software, they were able to find strong correlation between tumor volume and T-stage. Additionally, the lengths of the major and minor axis of the tumor were also found to correlate with T-stage. Their results provide three critical properties that can be used to assist in the clinical determination of T-stage.</p> <div id="attachment_1466" style="width: 2058px" class="wp-caption aligncenter"><img decoding="async" aria-describedby="caption-attachment-1466" class="size-full wp-image-1466" src="https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-2_2048x1816.jpg" alt="Major and minor axes of esophageal cancer tumors at different T-stages, reconstructed with Amira Software." title="Major and minor axes of esophageal cancer tumors at different T-stages, reconstructed with Amira Software." width="2048" height="1816" srcset="https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-2_2048x1816.jpg 2048w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-2_2048x1816-300x266.jpg 300w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-2_2048x1816-1024x908.jpg 1024w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-2_2048x1816-768x681.jpg 768w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-2_2048x1816-1536x1362.jpg 1536w, https://www.thermofisher.com/blog/atomic-resolution/wp-content/uploads/sites/22/2024/06/Tumor-Volume-Oesophageal-Cancer-Blog-Figure-2_2048x1816-310x274.jpg 310w" sizes="(max-width: 2048px) 100vw, 2048px" /><p id="caption-attachment-1466" class="wp-caption-text">Major and minor axes of esophageal tumors at different T-stages, reconstructed with Amira Software.

As we collect more and more information with advanced tools and techniques, it only becomes ever more important that we find ways to analyze and interpret that wealth of data. Versatile tools like Amira Software, with integrated automation and AI capabilities, allow you to extract critical details from your observations, leading to valuable insights that can shape clinical procedures and ultimately improve the lives of patients.</p> <p><a href="https://onlinelibrary.wiley.com/doi/10.1002/cam4.6051">Read the full article here &gt;&gt;</a></p> <p><a
