Towards Unsupervised Cancer Subtyping: Predicting Prognosis Using A Histologic Visual Dictionary [PDF]

arXiv, 2019
Unlike common cancers, such as those of the prostate and breast, tumor grading in rare cancers is difficult and largely undefined because of small sample sizes, the sheer volume of time needed to undertake on such a task, and the inherent difficulty of extracting human-observed patterns.

Selecting Regions of Interest in Large Multi-Scale Images for Cancer Pathology [PDF]

arXiv, 2020
Recent breakthroughs in object detection and image classification using Convolutional Neural Networks (CNNs) are revolutionizing the state of the art in medical imaging, and microscopy in particular presents abundant opportunities for computer vision algorithms to assist medical professionals in diagnosis of diseases ranging from malaria to cancer ...

Role of Adjuvant Chemotherapy in Distal Cholangiocarcinoma

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background Recent studies addressing the role of adjuvant chemotherapy (AC) in cholangiocarcinoma (CCA) have been published; however, there are challenges in generalizing the findings due to different prognostic characteristics depending on tumor location and resectability.

Treatment of recurrent intrahepatic cholangiocarcinoma

British Journal of Surgery, 2012
Abstract Background The aims of this study were to evaluate risk factors for recurrence following hepatectomy with curative intent for intrahepatic cholangiocarcinoma (ICC), and predictors of survival after intrahepatic recurrence. Methods

Current State of Evidence for Use of MRI in LI‐RADS

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT The American College of Radiology Liver Imaging Reporting and Data System (LI‐RADS) is the preeminent framework for classification and risk stratification of liver observations on imaging in patients at high risk for hepatocellular carcinoma.

Genomic Profiling of Biliary Tract Cancers: Comprehensive Assessment of Anatomic and Geographic Heterogeneity, Co‐Alterations and Outcomes

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background Biliary tract cancers (BTCs) represent distinct biological and genomic entities. Anatomic and geographic heterogeneity in genomic profiling of BTC subtypes, genomic co‐alterations, and their impact on long‐term outcomes are not well defined.

Molecular heterogeneity in intrahepatic cholangiocarcinoma

World Journal of Hepatology, 2020
Intrahepatic cholangiocarcinoma (iCCA) is a heterogeneous primary liver cancer, and currently there exist only a few options of targeted therapy. Histopathologically, iCCA is sub-classified according to morphology (mass forming type, periductal infiltrating type, and intraductal growing type) and histology (small duct type and large duct type ...

Heterogeneity of Intratumoral Microbiota Within the Tumor Microenvironment and Relationship to Tumor Development

Med Research, EarlyView.
Mutual shaping of tumor microbiota and TME. Intratumoral microbiota—comprising diverse bacteria, fungi, viruses, and intracellular organisms—play critical and dynamic roles in shaping the tumor microenvironment (TME). Their spatial and compositional diversity contributes to both intratumoral and intertumoral heterogeneity, influencing immune modulation

Intratumoral heterogeneity of intrahepatic cholangiocarcinoma

Oncotarget, 2017
335 Background: No personalized therapy regimens could demonstrate a benefit in survival in intrahepatic cholangiocarcinoma (iCCA). Since genetic heterogeneity might influence single biopsy based targeted therapy or the outcome of clinical trials, aim of the present study was to investigate intratumoral heterogeneity of iCCA by whole exome sequencing.
