Ovarian metastases originating from breast cancer represent a range of 3-30% of all ovarian neoplasms. Case Report: Herein, we present the histopathological, histochemical, and immunohistochemical findings of a rare case involving mucin-producing lobular breast carcinoma metastasizing to an ovarian fibroma in an 82-year-old female previously diagnosed with lobular breast carcinoma.

Artificial intelligence in improving the outcome of surgical treatment in colorectal cancer.

Background: A considerable number of recent research have used artificial intelligence (AI) in the area of colorectal cancer (CRC). Surgical treatment of CRC still remains the most important curative component. Artificial intelligence in CRC surgery is not nearly as advanced as it is in screening (colonoscopy), diagnosis and prognosis, especially due to the increased complexity and variability of structures and elements in all fields of view, as well as a general shortage of annotated video banks for utilization.

The role of computer-assisted systems for upper-endoscopy quality monitoring and assessment of gastric lesions.

This article analyses the literature regarding the value of computer-assisted systems in esogastroduodenoscopy-quality monitoring and the assessment of gastric lesions. Current data show promising results in upper-endoscopy quality control and a satisfactory detection accuracy of gastric premalignant and malignant lesions, similar or even exceeding that of experienced endoscopists. Moreover, artificial systems enable the decision for the best treatment strategies in gastric-cancer patient care, namely endoscopic vs surgical resection according to tumor depth.

The Impact of Artificial Intelligence in the Endoscopic Assessment of Premalignant and Malignant Esophageal Lesions: Present and Future.

In the gastroenterology field, the impact of artificial intelligence was investigated for the purposes of diagnostics, risk stratification of patients, improvement in quality of endoscopic procedures and early detection of neoplastic diseases, implementation of the best treatment strategy, and optimization of patient prognosis. Computer-assisted diagnostic systems to evaluate upper endoscopy images have recently emerged as a supporting tool in endoscopy due to the risks of misdiagnosis related to standard endoscopy and different expertise levels of endoscopists, time-consuming procedures, lack of availability of advanced procedures, increasing workloads, and development of endoscopic mass screening programs. Recent research has tended toward computerized, automatic, and real-time detection of lesions, which are approaches that offer utility in daily practice.

Predictors of rebleeding and in-hospital mortality in patients with nonvariceal upper digestive bleeding.

Background: Nonvariceal upper digestive bleeding (NVUDB) represents a severe emergency condition and is associated with significant morbidity and mortality.

Prognostic significance of E-cadherin expression in hepatocellular carcinoma: correlations with clinical features.

Background: Hepatocellular carcinoma (HCC) represents a major public health issue, being associated with high morbidity and mortality rates. Previous studies have demonstrated that reduction and∕or absence of E-cadherin expression is correlated with a potential for invasion and low survival rate in patients with HCC.

Patients, Materials And Methods: We assessed the immunohistochemical expression of E-cadherin in 32 HCCs and peritumoral hepatic tissues using monoclonal anti-E-cadherin antibody (clone EP700Y), at 1:50 dilution, followed by incubation with Labeled Streptavidin-Biotin 2 (LSAB2) for 20 minutes, visualization of the reaction with 3,3'-Diaminobenzidine (DAB) and counterstaining with Mayer's Hematoxylin.

Prognostic significance of tumor immune microenvironment and immunotherapy: Novel insights and future perspectives in gastric cancer.

Despite a decrease in gastric cancer incidence, the development of novel biologic agents and combined therapeutic strategies, the prognosis of gastric cancer remains poor. Recently, the introduction of modern immunotherapy, especially using immune checkpoint inhibitors, led to an improved prognosis in many cancers. The use of immunotherapy was also associated with manageable adverse event profiles and promising results in the treatment of patients with gastric cancer, especially in heavily pretreated patients.

Vitamin D deficiency in a European inflammatory bowel disease inception cohort: an Epi-IBD study.

Methods: Newly diagnosed IBD patients were included and followed prospectively for 1 year in 29 European and one Australian centre.

New advances in targeted gastric cancer treatment.

Despite a decrease in incidence over past decades, gastric cancer remains a major global health problem. In the more recent period, survival has shown only minor improvement, despite significant advances in diagnostic techniques, surgical and chemotherapeutic approaches, the development of novel therapeutic agents and treatment by multidisciplinary teams. Because multiple genetic mutations, epigenetic alterations, and aberrant molecular signalling pathways are involved in the development of gastric cancers, recent research has attempted to determine the molecular heterogeneity responsible for the processes of carcinogenesis, spread and metastasis.

Ki-67 and p53 immunostaining assessment of proliferative activity in salivary tumors.

Salivary gland tumors are rare neoplasias with approximately 34 different histological types. Because they have a considerably histological and biological behavior variability, salivary gland tumors represent a challenge both for the pathologist and the surgeon regarding their diagnosis, prognosis and treatment. Evaluation of mitotic index in case of Ki-67 and p53 expression has proved to be useful in predicting the biological aggressiveness in many tumors.
