Undifferentiated giant cell type carcinoma of the gallbladder with sarcomatoid dedifferentiation: a case report and review of the literature

Journal of Medical Case Reports, 2009
Introduction Undifferentiated gallbladder carcinoma is a rare entity. Among unusual types of undifferentiated gallbladder carcinoma, giant cell type carcinoma is infrequent and, moreover, very few cases of such neoplasms with osteoclast-like giant cells ...

NeoUNet: Towards accurate colon polyp segmentation and neoplasm detection [PDF]

arXiv, 2021
Automatic polyp segmentation has proven to be immensely helpful for endoscopy procedures, reducing the missing rate of adenoma detection for endoscopists while increasing efficiency. However, classifying a polyp as being neoplasm or not and segmenting it at the pixel level is still a challenging task for doctors to perform in a limited time.

Association between surgical difficulty and tumor location based on subsegments of the Glisson branches in laparoscopic liver resection

Annals of Gastroenterological Surgery, EarlyView.
Our study validates the need for a more detailed and accurate tumor location scoring system within the IWATE criteria. The proposed classification based on subsegmental Glisson branches provides a sophisticated tool for assessing LLR difficulty. By providing a more detailed assessment, this new system has the potential to enhance surgical planning ...

Gallbladder Cancer Detection in Ultrasound Images based on YOLO and Faster R-CNN [PDF]

2024 10th International Conference on Artificial Intelligence and Robotics (QICAR) (pp. 227-231). IEEE
Medical image analysis is a significant application of artificial intelligence for disease diagnosis. A crucial step in this process is the identification of regions of interest within the images. This task can be automated using object detection algorithms.

Higher order organizational features can distinguish protein interaction networks of disease classes: a case study of neoplasms and neurological diseases [PDF]

arXiv, 2022
Neoplasms (NPs) and neurological diseases and disorders (NDDs) are amongst the major classes of diseases underlying deaths of a disproportionate number of people worldwide. To determine if there exist some distinctive features in the local wiring patterns of protein interactions emerging at the onset of a disease belonging to either of these two ...

Possibly more favorable short‐term outcomes with minimally invasive surgery than with open surgery in total gastrectomy for locally advanced gastric cancer: A single high‐volume center study

Annals of Gastroenterological Surgery, EarlyView.
The MTG group had a significantly lower incidence of severe postoperative complications than the OTG group. Moreover, the incidences of pancreatic fistula and intra‐abdominal abscess were also significantly lower in the MTG than in the OTG group. Additionally, the median hospital stay for the MTG group was significantly shorter than that of the OTG ...

Cytokeratin 13 (CK13) expression in cancer: a tissue microarray study on 10,439 tumors

APMIS, Volume 131, Issue 2, Page 77-91, February 2023., 2023
Cytokeratin 13 (CK13) is a type I acidic low molecular weight cytokeratin, which is mainly expressed in urothelium and in the squamous epithelium of various sites of origin. Loss of CK13 has been implicated in the development and progression of squamous epithelial neoplasms. To comprehensively determine CK13 expression in normal and neoplastic tissues,

A Hierarchical Transformer Encoder to Improve Entire Neoplasm Segmentation on Whole Slide Image of Hepatocellular Carcinoma [PDF]

arXiv, 2023
In digital histopathology, entire neoplasm segmentation on Whole Slide Image (WSI) of Hepatocellular Carcinoma (HCC) plays an important role, especially as a preprocessing filter to automatically exclude healthy tissue, in histological molecular correlations mining and other downstream histopathological tasks.

Updated risk prediction model for pancreaticoduodenectomy using data from the National Clinical Database in Japan

Annals of Gastroenterological Surgery, EarlyView.
The calibration plots of the updated risk models for the endpoints were analyzed in each cohort. The predicted probability of each endpoint matched the observed probability in the development and validation cohorts. Abstract Aim Risk prediction models for mortality, severe postoperative complications, and postoperative pancreatic fistula in patients ...
