Overall, RSNA 2017 is expected to include at least 18 scientific paper presentations featuring TexRAD® Computed Tomography Texture Analysis (CTTA) and Magnetic Resonance Texture Analysis (MRTA), many of which have won awards in this year’s RSNA categories. Further information can be found at https://rsna2017.rsna.org/program.
Dr Balaji Ganeshan, Director of New Business at Feedback plc, said: “RSNA is the premier global event for radiologists and the increasing focus on our TexRAD® technology is encouraging. As seen in previous years, our renowned customers will highlight multiple TexRAD® presentations across various disease indications, further emphasising the significance of our technology across the healthcare industry. We look forward to discussing TexRAD® with this year’s RSNA delegates.”
TexRAD® is the Company’s patented quantitative image texture analysis technology for diagnostic radiological scans. The technology has the potential to assist clinicians in diagnosis, prognosis and treatment of patients with cancer, or other disease indications, and is currently installed in over 40 of the world’s leading research institutions across Europe, North America, Asia and Australasia. By analysing the texture features in computerised tomography (CT) scans, magnetic resonance images (MRI) and positron emission tomography scans (PET/CT), TexRAD®‘s quantitative imaging capabilities provide clinicians with additional, visually imperceptible information to make better decisions in order to improve patient outcomes.
TexRAD® research to date has shown great potential in many different oncological and non-oncological sites. In particular, the papers being presented at RSNA 2017 focus on liver, pancreatic, kidney, cervical, oral, genitourinary, head & neck, thyroid, neuroendocrine and endometrial cancers, as well as gastrointestinal stromal tumours, gliomas, thymic-epithelial neoplasms and carotid-plaques. On 20 November 2017, Feedback announced the CE marked release of TexRAD® Lung, a “software only” Class 1 medical device, to help advance lung cancer diagnosis. Further information on the TexRAD®technology can be found at www.texrad.com.

Feedback plc #FDBK – First CE marked release of TexRAD® technology
Feedback plc (AIM: FDBK), the specialist medical imaging technology company, announces the first CE marked release of TexRAD®; the Company’s patented quantitative image texture analysis technology for diagnostic radiological scans.
TexRAD® has the potential to assist clinicians in diagnosis, prognosis and treatment of patients with cancer and is currently installed in over 40 of the world’s leading research institutions across Europe, North America, Asia and Australasia. Feedback’s subsidiary company, Cambridge Computed Imaging Ltd, has affixed a CE mark to “TexRAD® Lung”; a “software only” Class 1 medical device providing additional information for the interpretation of computerised tomography (CT) and positron emission tomography (PET) scans of patients with lung cancer. The CE mark confirms that TexRAD® Lung meets the requirements of the Medical Device Directive (MDD – 93/42EEC) ensuring the technology satisfies the quality, safety and performance standards for medical devices in the European Union (EU).
Lung cancer has been the most common cancer in the world for several decades, estimated at 13% of all cancer diagnoses globally. It is also the most common cause of death from cancer worldwide, estimated to be responsible for nearly one in five. In the EU alone there are approximately 417,000 new cases of lung cancer every year. Radiologists are under significant pressure due to increasing patient numbers, more examinations required per patient and the need for earlier diagnosis. By analysing the texture features in CT scans, TexRAD®‘s quantitative imaging capabilities provide clinicians with additional information to make better decisions in order to improve patient outcomes.
Dr Alastair Riddell, Chairman at Feedback plc, said: “TexRAD® Lung is our first TexRAD® product with a CE mark which represents a significant accomplishment. This development will expedite TexRAD®‘s clinical use in the treatment of lung cancer across the EU, expand its market presence and support the Company’s ongoing commercial discussions for the technology. We expect that the rigorous regulatory review required for the CE mark will pave the way for TexRAD®‘s clinical use worldwide and we are now investigating the clinical application of TexRAD®in liver cancer and chronic obstructive pulmonary disease (COPD). By arming clinicians with disease-specific tools, we believe this technology has the potential to transform radiological decision making.”

Chairman’s statement
FINANCIAL PROGRESS
In the year ended 31 May 2017, the Group incurred a loss after tax of £266,003 (2016: loss £183,156) on revenue of £465,885 (2016: £431,454). The results show a continuation in revenue growth as more customers around the world adopt TexRAD® and Cadran products and associated support services. On 26 April 2017, we announced the completion of a placing of 27,272,727 new Ordinary Shares at a price of 2.75 pence per share to raise a total of £750,000 (before expenses). A proportion of the net proceeds from the share issue has been invested in product development, sales and marketing with the balance being utilised for general working capital purposes. This accelerated expenditure, including investing in the team and external activities, has contributed to the increase in the loss during the period, however the Directors expect that the benefits of this investment will be seen in the current financial year. Operational cash generation has been satisfactory and reflects customer payments for new purchases and contracts before the periods in which the revenue is recognised. The share issue, net of costs, has contributed to a healthy cash balance at the end of the year.
OPERATIONAL PROGRESS
As previously announced, Feedback’s subsidiary company, Cambridge Computed Imaging Ltd (“CCI”) is working towards a CE marked release of “TexRAD® Lung” for the clinical application of TexRAD® in the diagnosis, prognosis and treatment of lung cancer. CE marking is a claim by a medical device manufacturer that a product meets the essential requirements of the Medical Device Directive, which outlines the safety and performance requirements for medical devices in the European Union. TexRAD® Lung will be a “software only” medical device providing additional information for the interpretation of computerised tomography (CT) and positron emission tomography (PET) scans.
Feedback is committed to offering its customers the highest quality service across all areas of its business, and therefore compliance with international quality management standards is of paramount importance. CCI received certification for its compliance with the ISO 13485:2016 quality management standard in September 2017. In May 2017, Feedback announced that CCI had identified enhancements to improve the performance of TexRAD® which will further support the wider clinical application of the TexRAD® technology. Since then, CCI has successfully prepared a “release candidate” version of TexRAD® Lung, incorporating over 60 risk control measures to address the 50 potential clinical risk scenarios identified within the product. This in now in the final stages of testing, with an anticipated CE marked release by the end of November 2017.
On 30 March 2017, as part of the intended distribution arrangements, CCI signed a letter of intent with a leading global medical imaging company which would make TexRAD® Lung available for purchase on its diagnostic imaging solutions platform. This would, in due course, enable easy access to TexRAD® Lung for hundreds of potential users around the world on a subscription basis. We look forward to continuing our ongoing discussions with this company and other leading imaging companies to broaden the range of potential routes to market for clinical versions of TexRAD®.
Post-period end, CCI signed exclusive distributor agreements with Korea Computer Motion ISG in June 2017 and Boya Digital Technology (Beijing) Co. Ltd. in July 2017 for sales and distribution of TexRAD® in South Korea and the People’s Republic of China, respectively.
These agreements represent a significant step in expanding TexRAD® sales to meet the fast-growing demand in Asian markets. By successfully identifying and engaging with distributors who are experts in the local market, we can leverage the TexRAD® brand to help build a regional sales pipeline. Over the first few months of these agreements, joint marketing and promotional activities have been well-received, we have seen an increase in purchase orders for TexRAD® from leading medical institutions in South Korea and we are receiving significant interest in China.
In September 2016, we announced that we have developed a technical solution with Alliance Medical Group that would allow the integration of TexRAD® into Alliance’s network of PET/CT scanners in UK hospitals. A prototype version has been demonstrated to potential users and an abstract was presented at the Radiological Society of North America (RSNA) annual conference in November 2016. The poster, entitled “PET/CT in Lung Cancer: An Automated Imaging Tool for Decision Support”, highlighted results from a preliminary study which suggests that an automated PET/CT lung cancer tool may standardise clinical performance whilst allowing access to quantitative texture analysis to improve prognostication and fit within clinical workflow. We continue to work closely with Alliance on the future integration of TexRAD® Lung.
In March 2017, the Company announced that CCI was finalising arrangements for the secure transfer of patient data from Papworth Hospital NHS Foundation Trust to the new Cambridge Biomedical Campus which was expected to open in April 2018. Papworth Hospital has since extended the timeframe to September 2018 and therefore preparation for the transfer of the extensive archive of medical images is ongoing.
RESEARCH AND DEVELOPMENT PROGRESS
In July 2016, we announced a large-scale collaboration with Future Processing Sp. z o.o. (“Future Processing”), a software development service provider based in Gliwice, Poland to develop medical imaging software. The collaboration will entail a substantially increased development team working on new products and the sharing of intellectual property and future revenues. We believe that by CCI working jointly with the Future Processing healthcare team, CCI’s existing product portfolio can be improved and new products developed more rapidly including further applications for TexRAD®. The collaboration is fully underway and both teams are working towards agreeing formal licences for new software products to be brought to market in 2018.
We continue to receive significant TexRAD® research interest from prestigious institutions worldwide which has resulted in multiple articles in leading publications. In September 2016, University College London (“UCL”) published a retrospective study of 67 prostate cancer patients which demonstrated that TexRAD® analysis of multi-parametric MRI images may be able to identify the presence of clinically significant prostate cancers in the transition zone and therefore could potentially assist in optimising prostate radiologists’ workflow. In November 2016, we attended the 102nd Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA 2016); the premier global event for radiologists. We had a strong presence at RSNA 2016, with 19 scientific paper presentations featuring TexRAD®analysis, further emphasising the significance of our technology across the healthcare industry. Further information on the papers presented at RSNA 2016 can be found at https://rsna2016.rsna.org/program/.
Post-period end in October 2017, our customer at the International University of Health and Welfare Hospital in Tochigi, Japan published article featuring TexRAD® analysis in liver cancer. The paper, entitled “Impact of hepatocellular carcinoma heterogeneity on computed tomography as a prognostic indicator” was published in the Nature affiliated journal; Scientific Reports. We also sponsored the American British Course in Neuroradiology in Mumbai, India in October 2017, which included a lunch-time symposium presentation on brain texture analysis using TexRAD® technology. These research activities continue to support the potential future clinical application of TexRAD® in these other disease indications.
In 2015, we announced the incorporation of a 50:50 joint venture company, Prostate Checker Ltd, with QUIBIM S.L. (“QUIBIM”). The Board has concluded that a joint venture vehicle is no longer required for the collaboration. The Company continues to work closely with QUIBIM to develop a specific application of TexRAD® texture analysis for the computer assisted detection and diagnosis of prostate cancer.
BOARD AND ORGANISATION
Tom Charlton stepped down as a director on 30 May 2017 in order to devote more time to his other investment activities. Post-period end, on 8 June 2017, we announced that Trevor Brown resigned as a non-executive Director in order to allow the Company to move rapidly to the next stage in its development. On behalf of the Board, I thank both Tom and Trevor for their invaluable support of the Company following its readmission in 2014 which has enabled it to achieve considerable progress to date.
To further support the Company’s growth strategy, Tim Irish joined the Board on 8 June 2017 as Non-Executive Director. Tim is a Professor of Practice at Kings College London as well as a board member of Bournemouth University. He joined the board of the National Institute for Health and Care Excellence (NICE) in April 2015 and became its Senior Independent Director in May 2017. Tim has worked in the life sciences industry for 30 years. His career has spanned global health technology companies across Europe and North America, including GSK, GE and Philips the latter two in senior positions responsible for medical imaging. Tim also currently holds a number of non-executive positions in health and technology related entities.
I would also like to recognise and thank the Group’s employees for the outstanding contribution they have made. Having completed the placing in April 2017, we are in strong position to continue to build and invest in a leading team to deliver our objectives.
STRATEGY AND OUTLOOK
Upon delivery of the first CE marked release of TexRAD® by the end of November 2017, our ambition is to leverage our leading research, image processing and analysis expertise to position TexRAD® technology for routine clinical use to drive future revenue growth. We look forward to continuing our ongoing discussions with leading imaging companies to broaden the range of potential routes to market for clinical versions of TexRAD®. Our existing and future distributor agreements will continue to support the Company’s international expansion, ensuring that our technology continues to be used by the world’s leading institutions to expedite research in this important field. With pioneering technology platforms and strong industry trends, we believe the Group is ideally placed to deliver continued growth.

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 MAY 2017
1. General information
The Company is a public limited company domiciled in the United Kingdom and incorporated under registered number 00598696 in England and Wales. The Company’s registered office is Unit 5, Grange Park, Broadway, Bourn, Cambridgeshire, CB23 2TA.
The Company is listed on AIM of the London Stock Exchange. These Financial Statements were authorised for issue by the Board of Directors on the 6 November 2017.
While the financial information included in this preliminary announcement has been prepared in accordance with International Financial Reporting Standards (IFRSs), this announcement does not itself contain sufficient information to comply with IFRSs. The Group has also published full financial statements that comply with IFRSs available on its website and to be circulated shortly.
The financial information set out in the announcement does not constitute the company’s statutory accounts for the years ended 31 May 2017 or 2016. The financial information for the year ended 31 May 2016 is derived from the statutory accounts for that year, which were prepared under IFRSs, and which have been delivered to the Registrar of Companies.
The financial information for the year ended 31 May 2017 is derived from the audited statutory accounts for the year ended 31 May 2017 on which the auditors have given an unqualified report, that did not contain a statement under section 498(2) or 498(3) of the Companies Act 2006 and included the following paragraphs:
“Emphasis of matter – Going Concern
In forming our opinion, which is not modified, we have considered the adequacy of the disclosures made in Note 3c of the accounting policies regarding the group and parent company’s ability to continue as a going concern. The group incurred a loss of £266,003 in the year and may need to obtain further finance during the next twelve months which has not yet been obtained. These factors, along with the matters explained in note 3c of the accounting policies indicate the existence of a material uncertainty which may cast a significant doubt about the group and the company’s ability to continue as a going concern.
The financial statements do not include the adjustments that would result if the group and company were unable to operate as a going concern.”
The statutory accounts will be delivered to the Registrar of Companies following the Company’s annual general meeting.
2. Adoption of new and revised International Financial Reporting Standards
No new International Financial Reporting Standards (“IFRS”), amendments or interpretations became effective in the year ended 31 May 2017 which had a material effect on this financial information.
At the date of approval of this financial information, the following IFRS Standards and Interpretations, which have not been applied in these Financial Statements, were in issue but not yet effective. These new Standards, Amendments and Interpretations are those in issue but not yet effective which are expected to apply to the Group and are effective for accounting periods beginning on or after the dates shown below:
IFRS Standards and Interpretations issued (and EU adopted) but not yet effective:
Mandatory for accounting periods commencing on or after 1 January 2017:
· Amendments to IAS 12 – Recognition of Deferred Tax Assets for Unrealised Losses
· Amendments to IAS 7 – Disclosure Initiative
· Annual improvements to IFRS Standards 2014-2016 Cycle
Mandatory for accounting periods commencing on or after 1 January 2018:
· IFRS 9 – Financial Instruments
· IFRS 15 – Revenue from Contracts with Customers
· IFRIC Interpretation 22 – Foreign Currency Transactions and Advance Consideration
Mandatory for accounting periods commencing on or after 1 January 2019:
· IFRS 16 – Leases
Date of implementation in the European Union not yet known:
· IFRS 14 – Regulatory Deferral Accounts
The Group has not early adopted these amended standards and interpretations. The Directors do not anticipate that the adoption of these standards and interpretations will have a material impact on the reported results.
3. SIGNIFICANT ACCOUNTING POLICIES
(a) Basis of preparation
These financial statements have been prepared in accordance with those IFRS standards and IFRIC interpretations issued and effective or issued and early adopted as at the time of preparing these statements. The policies set out below have been consistently applied to all the years presented.
No separate income statement is presented for the parent Company as provided by Section 408, Companies Act 2006.
(b) Basis of consolidation
The Group financial statements consolidate the financial statements of Feedback plc and its subsidiaries (the “Group”) for the years ended 31 May 2017 and 2016 using the acquisition method.
The financial statements of subsidiaries are prepared for the same reporting year as the parent company, using consistent accounting policies. All inter-company balances and transactions, including unrealised profits arising from them, are eliminated. Subsidiaries are fully consolidated from the date on which control is transferred to the Group and cease to be consolidated from the date on which control is transferred out of the Group.
(c) Going Concern
On 26 April 2017 the Company raised a total of £750,000 (before expenses) through a placing to both invest further in the product development and sales and marketing of TexRAD, Feedback’s patented quantitative imaging software, and also for general working capital purposes.
Having updated the Group’s formal business plan the Directors consider that the Group and the Company are likely to have access to adequate cash resources for at least the next twelve months, from both existing cash balances and by obtaining further equity finance from the financial markets, or alternative funding, if required to enable continued product development and international expansion. Although this further finance has not yet been obtained, the Directors are confident that adequate additional finance will be forthcoming should it be required. Accordingly, the Directors believe that the Group and Company are a going concern and have therefore prepared the financial statements on a going concern basis.
4. LOSS PER SHARE
Basic earnings per share is calculated by reference to the loss on ordinary activities after taxation of £266,003 (2016: £183,156) and on the weighted average of 232,879,771 (2016: 203,514,709) shares in issue.

In accordance with the accounting policies and IFRS the Directors have assessed the carrying value of the intangible assets. In the year ended 31 May 2015, the Directors took the prudent decision to write down the carrying value of the software development costs in the balance sheet in order to meet the requirements of IFRS. During the years ended 31 May 2017 and 2016 all similar development costs have been expensed as the provisions of IFRS have not been met. However the Directors believe the Group’s technology has great potential and this write down does not reflect their commercial assessment of the value of the Group’s intellectual property. Expenditure on software development is being written off as incurred until the provisions of IFRS are met. The customer lists and patents are deemed to have ongoing value to the Group.

Impact of hepatocellular carcinoma heterogeneity on computed tomography as a prognostic indicator – Feedback Plc (FDBK)
Paper published in Scientific Reports (“Nature” affiliated journal) by Professor Shigeru Kiryu, Department of Radiology, International University of Health and Welfare Hospital, Nasushiobara, Tochigi, Japan.
Abstract
We assessed the relationship between the heterogeneity of HCC on preoperative non-contrast-enhanced CT and patient prognosis. The heterogeneity of CT images from 122 patients was assessed and texture feature parameters such as mean, standard deviation (SD), entropy, mean of the positive pixels (MPP), skewness, and kurtosis were obtained using filtration. The relationship between CT texture features and 5-year overall survival (OS) or disease-free survival (DFS) was assessed. Multivariate regression analysis was performed to evaluate the independence of texture feature from clinical or pathological parameters. The Kaplan-Meier curves for OS or DFS was significantly different between patient groups dichotomized by cut-off values for all CT texture parameters with filtration at at least one filter level. Multivariate regression analysis showed the independence of most CT texture parameters on clinical and pathological parameters for OS with filtration at at least one filter level and without filtration except kurtosis. SD, entropy, and MPP with coarse filter, and skewness without filtration showed a significant correlation for DFS. CT texture features of non-contrast-enhanced CT images showed a relationship with HCC prognosis. Multivariate regression analysis showed the possibility of CT texture feature increase the prognostic prediction of HCC by clinical and pathological information.
Introduction
The incidence of hepatocellular carcinoma (HCC) has increased due to the spread of hepatitis, and HCC is now the second leading cause of cancer-related death worldwide1. Because HCC has a high potential for vascular invasion, metastasis, and recurrence, its prognosis is poor. Among several therapies used to treat HCC, hepatic resection is considered the mainstay of curative therapy for localized HCC2,3. However, due to its high rate of recurrence after resection, preoperative prognostic prediction of HCC is important for the appropriate management of patients.
Heterogeneity is widely recognized as a feature of malignancy associated with adverse tumor biology, and it is assessed on medical images using a texture-analysis technique4. On computed tomography (CT), photon noise, caused by fluctuations in the number of photons in incident X-rays, obscures biologic heterogeneity4. CT texture analysis using filters to reduce photon noise is used for a variety of purposes, including assessment of malignant tumor prognosis5.
CT is widely used for the detection and assessment of HCC and is an indispensable preoperative examination. If information related to HCC prognosis is available from non-contrast-enhanced CT images, preoperative CT can provide additional meaningful data. The objective of this study was to assess the relationship between HCC heterogeneity and prognosis after the resection of HCC using non-contrast-enhanced CT texture analysis with a filter technique.
Materials and Methods
This study was approved by the Research Ethics Committee of our institution as a retrospective data analysis for medical imaging-based diagnoses, and the requirement for informed consent was waived by the Committee (26-73-1126). Additionally, all experiments and methods in this study were performed in accordance with the Declaration of Helsinki.
PatientsA total of 169 consecutive patients who underwent initial hepatectomy for HCC between January 2004 and September 2009 were included in this study. This study was approved by the Research Ethics Committee of the institution. A total of 16 patients were excluded due to the unavailability of CT images on the picture archiving system. We excluded a further 28 patients who underwent transcatheter arterial embolization (TACE) prior to CT, because the high density of deposited iodized oil may affect the texture features. A total of three patients with lesions too small (<1 cm) to evaluate on CT were additionally excluded. Finally, the study group consisted of 122 patients: 92 males (mean age, 63.5 years; range, 25–82 years) and 30 females (mean age, 69.2 years; range, 53–81 years). A total of 37 patients underwent TACE between CT and surgery (Table 1). Clinical patient’s information such as Child-Pugh score, serum levels of alpha-fetoprotein (AFP), tumor differentiation, pathological stage (pStage), or presence/absence of venous invasion was examined using database of surgical records.
CT examination
CT studies were performed using a 4-, 16-, or 64-detector row CT scanner (Light Speed QX/I, LightSpeed Ultra, LightSpeed VCT, GE Medical Systems, Milwaukee, WI, USA) or a 16-detector row CT scanner (Aquilion 16, Toshiba Medical Systems Corp., Tochigi, Japan). The same clinical protocol was used: 120 kV, 180–280 mAs depending on body habitus, a matrix of 512, and a field of view of 350–400 mm. Non-contrast CT was performed using a 5-mm contiguous axial section to encompass the whole liver. Non-contrast CT was mostly performed as part of the contrast-enhanced study.
Texture analysis
The location of the HCC was defined on unenhanced CT according to the surgical records, and the slice with the largest lesion was selected by one of the research conductors (a radiologist with 22 years of experience with abdominal CT). Images were loaded onto a workstation for further texture analysis. Texture analysis was performed by a single observer (a radiologist with 12 years of experience with abdominal CT) who was blinded to the clinical outcome, using TexRAD (TexRAD Ltd., www.texrad.com part of Feedback Plc., Cambridge, UK), a proprietary research software algorithm developed to visualize and quantify the texture properties of tissues from medical imaging scans. The region of interest (ROI) was initially delineated around the tumor periphery section by an observer and refined by excluding areas of air using a thresholding procedure that removed any pixels with attenuation values below −50 Hounsfield unit from the analysis. The assessment of texture feature comprised an initial filtration step in which a Laplacian of Gaussian spatial band-pass filter was used to selectively extract features of different sizes and intensity variations, at three different frequency scales: fine (features approximately 2 mm in width), medium (features approximately 4 mm in width) and coarse (features approximately 6 mm in width) (Fig. 1). The heterogeneity within the ROI was assessed with and without filtration, and texture parameters were calculated as follows: the mean grey-level intensity (mean), variation/dispersion from the mean grey-level intensity (standard deviation, SD), the irregularity or complexity of the grey signal (entropy), the average intensity of the positive grey-level signal pixel values within the ROI (mean of the positive pixels, MPP), asymmetry of the distribution (skewness), and pointiness or peakedness of the distribution (kurtosis)4,5. These parameters derived from the histogram analysis. SD, kurtosis and skewness describe the shape of the histogram representing the gray-level variation, asymmetry and peak with in the ROI, respectively. Entropy is a measure of texture irregularity and defined by following equation where l is the pixel levels (between l = 1 to k) in ROI, and p(l) is the probability of the occurrence of that pixel level.
Statistical analysis
The relationship between the CT texture features and 5-year overall survival (OS) or disease-free survival (DFS) was assessed by Kaplan-Meier analyses. Patients were dichotomized according to the best cut-off values, which were calculated by the log-rank test to classify the outcome of OS or DFS.
The multivariate Cox proportional hazard regression analysis using likelihood ratio test was performed to evaluate the independence of CT texture feature from clinical and pathological parameters, such as the Child-Pugh score, serum levels of AFP, tumor histological differentiation, pStage, or presence/absence of venous invasion, on OS or DFS. The correlations between CT texture features and clinical parameters were assessed: presence of HBs-Ag or HCV-Ab using paired-t-test; Child-Pugh classification, differentiation of HCC, or TNM stage using Spearman’s correlation; AFP using Pearson’s correlation. A P-value < 0.05 was considered to indicate statistical significance. The correlations of the CT texture features were assessed using the Spearman rank correlation coefficient. All statistical analyses were performed by a statistician using SPSS (version 18.0; IBM Corp, Armonk, NY, USA) statistical software.
Results
Of the total number of patients, 12 were stage I, 60 stage II, 35 stage III, 12 stage IVA, and 3 stage IVB (Table 1). A total of 60 patients had a Child-Pugh score of 5, 46 a score of 6, 13 a score of 7, 2 a score of 8, and 1 a score of 9.Patients with the Child-Pugh score of 8–9 had inherited constitutional jaundice. AFP levels above 400 ng/ml were observed in 22 (18%) patients and venous invasion in 38 (31%) patients. A total of 77 (63.1%) patients had a single HCC, 24 (19.7%) patients had two HCCs, and 21 (17.2%) patients had three or more HCCs. The histopathologic differentiation of the tumors was well in 26 (21.3%) patients, moderate in 82 (67.2%) patients, poor in 10 (8.2%) patients and necrosis in 4 (3.3%) patients. Sixty-two (50.8%) patients died within 5 years, and the median OS was 50.6 months. A total of 98 (80.3%) patients suffered HCC relapse within 5 years, and the median DFS was 19.8 months.
The Kaplan-Meier curves for OS or DFS was significantly different between patient groups dichotomized by cut-off values for all CT texture parameters with filtration at at least single filter level (Table 2, Fig. 2). For SD and entropy, OS was significantly different without filtration or with filtration at each filter level (fine, medium and coarse). OS was different without filtration or with filtration (medium) for skewness. For mean, MPP and kurtosis, OS was not different without filtration between patient groups, but it was different with filtration (fine, fine and medium and coarse, and fine and medium, respectively). DFS was significantly different for skewness and kurtosis without filtration or with filtration (fine and medium, fine and coarse, respectively). DFS was different for mean, SD, entropy and MPP with filtration at single filter level (fine, coarse, coarse, and coarse, respectively).

A review of potential applications by TexRAD users from leading Universities across the USA – Feedback (FDBK)
Feedback (FDBK) – A review of potential applications by TexRAD users from leading Universities across the USA.
Authors: Lubber MG, Smith AD, Sandrasegaran K, Sahani DV, Pickhardt PJ.
ABSTRACT: This review discusses potential oncologic and nononcologic applications of CT texture analysis ( CTTA CT texture analysis ), an emerging area of “radiomics” that extracts, analyzes, and interprets quantitative imaging features. CTTA CT texture analysis allows objective assessment of lesion and organ heterogeneity beyond what is possible with subjective visual interpretation and may reflect information about the tissue microenvironment. CTTA CT texture analysis has shown promise in lesion characterization, such as differentiating benign from malignant or more biologically aggressive lesions. Pretreatment CT texture features are associated with histopathologic correlates such as tumor grade, tumor cellular processes such as hypoxia or angiogenesis, and genetic features such as KRAS or epidermal growth factor receptor (EGFR) mutation status. In addition, and likely as a result, these CT texture features have been linked to prognosis and clinical outcomes in some tumor types. CTTA CT texture analysis has also been used to assess response to therapy, with decreases in tumor heterogeneity generally associated with pathologic response and improved outcomes.
A variety of nononcologic applications of CTTA CT texture analysis are emerging, particularly quantifying fibrosis in the liver and lung. Although CTTA CT texture analysis seems to be a promising imaging biomarker, there is marked variability in methods, parameters reported, and strength of associations with biologic correlates. Before CTTA CT texture analysis can be considered for widespread clinical implementation, standardization of tumor segmentation and measurement techniques, image filtration and postprocessing techniques, and methods for mathematically handling multiple tumors and time points is needed, in addition to identification of key texture parameters among hundreds of potential candidates, continued investigation and external validation of histopathologic correlates, and structured reporting of findings.
