GALNT2, also known as polypeptide N-acetylgalactosaminyltransferase 2, is an enzyme that catalyzes the initial step of O-linked glycosylation, a crucial posttranslational modification that affects protein folding, stability, and function. Alterations in GALNT2 activity have been implicated in various diseases, such as cancer, metabolic disorders, and cardiovascular diseases, highlighting its importance in maintaining normal physiological functions. To investigate the impact of GalNT2 overexpression in vivo for the first time, we generated a conditional transgenic mouse line in which GalNT2 was expressed specifically in the pancreas.

Article Synopsis
  • Anterior gradient 2 (AGR2) is a key protein involved in various biological processes like embryonic development, tissue regeneration, and wound healing, with potential implications in cancer research.
  • A comprehensive analysis of nearly 15,000 tumors and normal tissue samples revealed that AGR2 expression is present in a majority of tumor categories, particularly in tumors of the female genital tract and various adenocarcinomas.
  • High levels of AGR2 are associated with poor clinical outcomes in several cancer types, suggesting its role as a potential biomarker for tumor aggressiveness and progression.

Article Synopsis
  • Researchers developed a novel risk score using molecular markers to predict survival in colorectal cancer patients, moving beyond traditional histopathological methods.
  • The study analyzed 1791 patients using immunohistochemistry to measure the levels of H2BUB1, RBM3, and Ki-67, creating a scoring system based on these markers.
  • Results indicated that the new risk score could independently predict patient survival, potentially offering a more personalized approach to treatment than classical methods.

Colorectal carcinomas are a rare but possible complication in an interposed colonic segment used for reconstruction after esophagectomy. We report the case of a patient who underwent colonic interposition surgery in childhood due to esophageal atresia and was diagnosed with colorectal adenocarcinoma of the interposed colon ~57 years later. The patient underwent gastric pull-up after thoraco-abdominal resection of the colonic interposition en bloc with the adjacent remaining esophagus.

The role of CD10 expression in colorectal cancer has been controversially discussed in the literature. Some data suggest a predictive capacity for lymph node and liver metastases, thus influencing overall survival (OS) and disease-free survival (DFS). This study aims to analyse the relationship between CD10 expression and overall survival (OS) in a European cohort.

Differential glycosylation, marked by the presence of truncated O-glycans, is a distinctive feature of epithelial-derived cancers. However, there is a notable gap in research regarding the expression of Tn and STn antigens in esophageal adenocarcinoma (EAC). To address this, we employed commercially available antibodies, previously validated for Tn and STn antigens, to analyze two cohorts of EAC tissues.

Article Synopsis
  • Minimally invasive total gastrectomy (MITG) is an important surgical approach for treating gastric cancer, but there is currently no consensus on the best techniques for key processes like lymphadenectomy and anastomosis creation.
  • An international panel of expert surgeons participated in a study using the Delphi method, which involved multiple rounds of voting to establish consensus on the technical steps of MITG, resulting in 41 key statements after three rounds.
  • The consensus findings, showing high internal consistency, aim to improve surgical quality and outcomes for patients undergoing MITG by providing standardized techniques based on expert agreement.

Metastasis is a cancer-related systemic disease and is responsible for the greatest mortality rate among cancer patients. Interestingly, the interaction between the immune system and cancer cells seems to play a key role in metastasis formation in the target organ. However, this complex network is only partially understood.

Introduction: Emerging evidence suggests that deconditioned patients benefit most from prehabilitation before colorectal cancer surgery. So far, selecting patients with poor muscle status and high perioperative risk remains challenging. Therefore, this study evaluates the potential of the CT-derived Skeletal Muscle Index (SMI), representing muscle mass, and of the Muscle Radiation Attenuation (MRA), a measure of muscle quality, for risk stratification in colorectal cancer patients.

Purpose: With robotic surgical devices, an innovative tool has stepped into the arena of minimally invasive hernia surgery. It combines the advantages of open (low recurrence rates and ability to perform complex procedure such as transverse abdominis release) and laparoscopic surgery (low rate of wound and mesh infections, less pain). However, a superiority to standard minimally invasive procedures has not yet been proven.

Importance: To our knowledge, there are no complete population-based studies of the risks of developing second malignant tumors after papillary thyroid carcinoma (PTC) in patients following the Chernobyl nuclear accident.

Objective: To study the risk of second primary cancers in patients with PTC after the Chernobyl disaster.

Design, Setting, And Participants: This was a retrospective cohort study conducted in the Republic of Belarus over a 31-year time frame evaluating patients with primary PTC and second malignant tumors.

Background & Aims: Ulcerative colitis (UC) is characterized by severe inflammation and destruction of the intestinal epithelium, and is associated with specific risk single nucleotide polymorphisms in HLA class II. Given the recently discovered interactions between subsets of HLA-DP molecules and the activating natural killer (NK) cell receptor NKp44, genetic associations of UC and HLA-DP haplotypes and their functional implications were investigated.

Methods: HLA-DP haplotype and UC risk association analyses were performed (UC: n = 13,927; control: n = 26,764).

To determine whether a new surgical method using a flexible endoscope (FlexVATS) to perform sparing debridement and apply negative-pressure therapy without extensive decortication may be an alternative treatment option for empyema. Surgical treatment of pleural empyema is associated with considerable postoperative complications and mortality rates, and alternative treatment options are being explored to improve patient outcomes. This was a prospective case series.

An optimized lymph node yield leads to better survival in colon cancer, but extended lymphadenectomy is not associated with survival benefits. Lymphatic mapping shows several colon cancers feature aberrant drainage pathways inducing local recurrence when not resected. Currently, different protocols exist for lymphatic mapping procedures.

In Germany, socioeconomically deprived citizens more often develop esophageal carcinoma, since typical risk factors follow the social gradient. Therefore, we hypothesized that socioeconomic deprivation might also be associated with advanced tumor stages and comorbidities at the time of surgery. As a consequence, socioeconomic deprivation may be related to postoperative complications and reduced overall survival.

Background: The immune system plays a pivotal role in cancer progression. Interleukin 22 binding protein (IL-22BP), a natural antagonist of the cytokine interleukin 22 (IL-22) has been shown to control the progression of colorectal cancer (CRC). However, the role of IL-22BP in the process of metastasis formation remains unknown.

Purpose: The treatment of anastomotic leakage after left colorectal surgery remains challenging. Since its introduction, endoscopic negative pressure therapy (ENPT) has proven to be advantageous, reducing the necessity of surgical revision. The aim of our study is to present our experience with endoscopic treatment of colorectal leakages and to identify potential factors influencing treatment outcome.

Background: Necrotizing fasciitis (NF) is a rare but lethal soft-tissue infection. There is still a paucity of information regarding the diagnostic tools and therapeutic strategies for the treatment of this devastating disease. This study aims to identify important perioperative parameters related to necrotizing fasciitis and to assess their relevance in terms of identifying NF.

Early life is characterized by extraordinary challenges, including rapid tissue growth and immune adaptation to foreign antigens after birth. During this developmental stage, infants have an increased risk of immune-mediated diseases. Here, we demonstrate that tissue-resident, interleukin (IL)-13- and IL-4-producing group 2 innate lymphoid cells (ILC2s) are enriched in human infant intestines compared to adult intestines.
