  19. 19. Colorectal Background 1 Colorectal Background Facts about Colorectal Cancer Colorectal cancer is the second most common malignancy in Western societies [1]. 40% of the patients undergoing resection of the primary tumour will relapse and die of their disease, making colorectal cancer the second leading cause of death related to cancer [2]. The liver is the sole site of secondary tumour spread (i.e. metastasis) in 20-40% of patients [3] and therefore it is a common practice to follow-up patients after their curative resection [4]. There is an overall survival benefit for intensifying the follow-up of such patients with imaging of the liver being associated with reduced mortality (Odds ratio = 0.66, 95% confidence limits 0.46-0.95) [5]. 1 2 3 4 5 6 6 7 8 Case Study | Demo | Evidence
  20. 20. Colorectal Background 2 Colorectal Background Facts about Colorectal Cancer The American Society of Clinical Oncology (ASCO) now recommends annual CT of the chest and abdomen for 3 years after primary therapy for patients at higher risk of recurrence [6]. However, the risk of recurrence is not uniform for these patients and identification of predictive factors that are linked to outcomes may allow modification of surveillance strategies for particular sub-groups and provide effective and optimum patient care. ASCO has also highlighted the need for research in this area [6]. 1 2 3 4 5 6 6 7 8 Case Study | Demo | Evidence
  21. 21. Colorectal Background 3 Colorectal Background Comparison of Risk Stratification techniques Additional physiological imaging techniques such as Doppler ultrasound and quantitative analysis of liver contrast enhancement or perfusion on CT also have the potential to identify patients at higher risk of recurrence [7, 8] These techniques may reflect alterations of liver hemodynamics associated with occult metastases [9, 10]. However, the additional image acquisitions required by these techniques have been a barrier to their adoption into surveillance programs. (cost/additional radiation dosage) 1 2 3 4 5 6 6 Case Study | Demo | Evidence 7 8
  22. 22. Colorectal Evidence 1 Colorectal Evidence Why TexRAD is better - evidence TexRAD applied to routinely acquired CT images highlights subtle liver changes that may occur in association with alterations in liver physiology. Furthermore computer simulations and clinical studies have suggested that measurements of liver texture on CT may reflect liver vascularity [11-13]. The ability of Liver TexRAD to detect occult tumour on CT is further supported by studies demonstrating textural differences between normal livers and apparently normal areas of tissue within livers bearing tumours, areas also known to exhibit alterations in blood flow [13-15]. 1 2 3 4 5 6 6 Case Study | Demo | Evidence 7 8
  23. 23. Colorectal Evidence 2 Colorectal Evidence Why TexRAD is better - evidence Preliminary results of Liver TexRAD demonstrate the potential for liver texture on contrast-enhanced CT to provide a novel parameter that is not only insensitive to variations in acquisition parameters but can also act as a marker of survival for patients following resection of colorectal cancer [16]. 1 2 3 4 5 6 6 Case Study | Demo | Evidence 7 8

  28. 28. Lung Case Study Lung Case Study Typical example: A patient diagnosed with lung cancer requires an accurate staging of the tumour and lymph node disease. Radiologists are unable to obtain a confident risk stratification from CT alone, which is critical for early prognosis and favourable patient outcome. The patient undergoes FDG PET-CT imaging, which overcomes the limitations of CT alone. However, this is an additional and expensive procedure. TexRAD can improve the performance of CT and potentially be employed for selection of patients for PET. 1 2 3 4 5 6 6 7 8 HOW? Case Study | Demo | Evidence

  38. 38. Lung Background Lung - Background Facts about lung Cancer Lung cancer is the most common form of death related to cancer in men and second most common in woman [1, 2], accounting for 1.3 million deaths worldwide annually [3]. Non-small cell lung carcinoma (NSCLC) is the most common form of lung cancer prevalent in 80% of all cases [4]. Following initial diagnosis, patients with NSCLC undergo staging. The most common imaging staging procedure has been CT. However, due to low accuracy for CT staging, clinical guidelines now recommend Fluoro-deoxy-glucose (FDG) PET-CT unless the initial CT imaging shows evidence of inoperable disease. An improvement in the accuracy of CT could improve the selection of patients for FDG-PET. Case Study | Demo | Evidence 7 8 1 2 3 4 5 6

  45. 45. Breast Case Study Breast Case Study Typical example: A female participant within a breast screening program undergoes an initial mammogram examination. Further diagnostic mammogram confirms presence of cancerous tissue. Core biopsy identified non-invasive ductal carcinoma in situ (DCIS) and the standard breast conservation excision was performed. Surprisingly, the final excised specimen provided evidence of invasive focus, routinely underestimated by core biopsy, resulting in additional surgical procedure involving the axilla TexRAD could have predicted the risk of invasive disease preoperatively from mammographic lesions assisting in treatment planning and optimal selection of biopsy or surgery 1 2 3 4 5 6 6 7 8 HOW?

  46. 46. Breast CS 2 Breast Case Study How TexRAD supports clinician & patient in case study From routine mammographic images taken in the clinic TexRAD software uniquely extracts and measures fine , medium and coarse textures - in this example, from the breast lesion - and characterises differences in calcification architecture These texture differences can be used to preoperatively estimate the likelihood of invasive focus from among patients with DCIS This additional information may assist the clinician in better treatment planning and optimal selection of sentinel node biopsy or axillary surgery 1 2 3 4 5 6 6 7 8 Case Study | Demo | Evidence

  50. 50. Breast Demo 4 STAGE 1 - Display the target clinical image of interest A TexRAD analysis is applied to the appropriate 2D mammographic image highlighting the breast lesion (tissue of interest - TOI). The specialist clinical consultant (e.g. Radiologist) will select the image containing this TOI. Breast - Demo 1 2 3 4 5 6 6 7 Case Study | Demo | Evidence 8
  51. 51. Breast Demo 5 STAGE 2 – Draw region of interest (ROI) to be analysed Using TexRAD’s graphical user interface tools, image window level/width can be altered to clearly delineate this TOI, interactive magnification/panning/centring can be used for better visualisation of this TOI. Clinician can choose an appropriate ROI tool (e.g. Polygon ROI) from a list of options based on the application. This ROI is super-imposed on the TOI within the original image.

  52. 52. Breast Demo 6 Breast - Demo STAGE 3 – Texture Analysis TexRAD employs a novel algorithm (patent applied for) primarily to extracts subtle but prognostic metrics currently not available in clinic. The software also graphically displays clinically relevant fine, medium and coarse breast lesion textures separately (below) in addition to their fusion with the original mammographic image. 1 2 3 4 5 6 6 7 Case Study | Demo | Evidence 8

  55. 55. Breast Background 1 Breast - Background Facts about Breast Cancer Invasive cancer of the breast and DCIS can both present as focal lesions on mammography. Pure DCIS is not an invasive process and rarely metastasises to regional lymph nodes [1]. The introduction of mammographic breast screening has resulted in a dramatic increase in the diagnosis of DCIS and its detection rate has reached 15-20% of all mammographically detected cancers [2-4]. Based on core biopsy specimens, the standard surgical planning for DCIS is to offer breast conservation excision. 1 2 3 7 8 Case Study | Demo | Evidence 4 5 6
  56. 56. Breast Background 2 Breast - Background Facts about Breast Cancer However, the detection of DCIS on core biopsy is quite frequently followed by evidence of invasion within the final excision specimen. This occurs in 11-44% of patients and results in the need of second operative procedure involving the axilla [4, 5]. Therefore the main concern is whether any kind of axillary staging is indicated in patients preoperatively diagnosed with DCIS only. 1 2 3 7 8 Case Study | Demo | Evidence 4 5 6
  57. 57. Breast Background 3 Breast - Background Facts about Breast Cancer The most often employed axillary treatment option for patients with DCIS is to perform a sentinel node biopsy at the time of initial excision. Nevertheless it may lead to reoperation in cases of proven invasive focus on excision. Therefore an effective way of estimating the likelihood of an invasive focus preoperatively in patients diagnosed with DCIS would assist in better treatment planning and optimal use of sentinel node biopsy or axillary surgery. 1 2 3 7 8 Case Study | Demo | Evidence 4 5 6
