A case of Helicobacter pylori-negative early gastric adenocarcinoma with gastrointestinal phenotype
Endosc Int Open 2021; 09: E863-E866 DOI: 10.1055/a-1396-3854A 40-year-old man with slightly depressed (0-IIc) type gastric cancer of the pyloric anterior gastric area underwent pre-operative screening for tetralogy of Fallot and endoscopic submucosal dissection (ESD) and was tested for Helicobacter pylori antigens and antibodies. Both tests were negative. He did not have a history of eradication. Pathological diagnosis of ESD showed a well-differentiated adenocarcinoma. The tumor was CD10-positive, MUC5AC-negative, and MUC6-confocal positive; it showed differentiation with gastrointestinal phenotype. Moreover, the tumor cells were lysozyme-positive, resembling Paneth cells. Mucosal glands exhibited intestinal metaplasia on the anal side of the tumor lesion. On the oral side of the tumor, metaplasia was non-existent, with normal pyloric glands present in the mucosal layer. The patient was not infected with H. pylori; however, intestinal metaplasia existed around the early gastric cancer. This suggested that the intestinal metaplasia occurred due to bile reflux, and the gastric neoplasia arose with the metaplasia without an H. pylori infection. This case may potentially help explain gastric cancer development in the absence of H. pylori infection.

ConclusionThe DCE-MRI radiomics model, especially image features extracted from the delayed phases, can help improve the performance in predicting TILs. The radiomics nomogram is effective in predicting TILs in breast cancer.Key Points•Radiomics features extracted from DCE-MRI, especially delayed phase images, help predict TIL levels in breast cancer.•We developed a nomogram based on MRI to predict TILs in breast cancer that achieved the highest AUC of 0.950.
ConclusionWe observed strong reproducibility in the assessment of PI-QUAL between two radiologists with high expertise in prostate mpMRI. At present, PI-QUAL offers clinicians the only available tool for evaluating and reporting the quality of prostate mpMRI in a systematic manner but further refinements of this scoring system are warranted.Key Points•Inter-reader agreement for each single Prostate Imaging Quality (PI-QUAL) score (i.e., PI-QUAL 1 to PI-QUAL 5) was strong, with weighted kappa = 0.85 (95% confidence intervals: 0.51 – 1) and percent agreement = 84%.• Interobserver agreement was strong wh...
This study was designed to compare the detection of subtle lesions (calcification clusters or masses) when using the combination of digital breast tomosynthesis (DBT) and synthetic mammography (SM) with digital mammography (DM) alone or combined with DBT.MethodsA set of 166 cases without cancer was acquired on a DBT mammography system. Realistic subtle calcification clusters and masses in the DM images and DBT planes were digitally inserted into 104 of the acquired cases. Three study arms were created: DM alone, DM with DBT and SM with DBT. Five mammographic readers located the centre of any lesion within the images that s...

The number of people living with chronic immunosuppression is increasing in the United States. Patients with HIV, those who have had bone marrow or solid organ transplants, and patients taking biologics for autoimmune diseases are at increased risk for skin cancer. Skin cancer in these patients is more aggressive and more likely to metastasize and cause death. Medications and individual risk factors such as sex, age, and ethnicity are independent risk factors for the development of skin cancer. Routine screening and aggressive treatment of actinic keratoses and nonmelanoma skin cancers can reduce patients' skin cancer burd...

PANCREATIC cancer cells multiply in the organ's tissue, which is situated behind the stomach. Hardly detectable in the earliest of stages, if the tumour has spread, warning signs will emerge.
ConclusionPignat ’s partial laryngectomy with CHEPL can represent an alternative to horizontal supracricoid laryngectomy to achieve laryngeal preservation. Good oncologic and functional outcomes are possible as long as indications are followed.
