Landscape of B lymphocytes and plasma cells in digestive tract carcinomas.

Ann Gastroenterol

December 2024

2 Department of Pathology, Attikon University Hospital, Medical School, National and Kapodistrian University of Athens, Greece (Periklis G. Foukas).

Digestive tract carcinomas are the most commonly occurring cancers worldwide, but their prognosis with traditional treatments remains poor. T lymphocytes are well-recognized as crucial components of effective anti-tumor immunity, and current immunotherapeutic strategies concentrate mainly on T-cell-mediated immunity reinforcement, whereas the role of B lymphocytes and plasma cells (PCs) has been neglected in the past, and it is only recently that these cells have been considered as key players in the tumor microenvironment (TME). In this review, we describe the complex dual role of B lymphocytes and PCs in promoting and inhibiting tumor progression in the TME of digestive tract carcinomas, and we demonstrate their prognostic value.

Intrauterine growth restriction (IUGR) is the second most common obstetric complication after preterm labor. Appropriate trophoblast differentiation and placental structure, growth and function are key for the maintenance of pregnancy and normal fetal growth, development and survival. Extravillous trophoblast cell proliferation, migration and invasion are regulated by molecules produced by the fetomaternal interface, including autocrine factors produced by the trophoblast, such as insulin‑like growth factor (IGF)‑1.

Purpose: Neoadjuvant radiotherapy (RT) or chemoradiotherapy (CRT) is the standard treatment for locally advanced rectal adenocarcinoma. The recent emerging data on preoperative immunotherapy as an effective therapeutic modality for mismatch repair deficient rectal carcinomas suggests that the immune system plays a significant role in tumor eradication. Although RT has been shown to stimulate anti-tumor immunity, it also leads to substantial lymphopenia, hindering the effect of immune response.

The gastrointestinal tract can be deranged by ailments including sepsis, trauma and haemorrhage. Ischaemic injury provokes a common constellation of microscopic and macroscopic changes that, together with the paradoxical exacerbation of cellular dysfunction and death following restoration of blood flow, are collectively known as ischaemia-reperfusion injury (IRI). Although much of the gastrointestinal tract is normally hypoxemic, intestinal IRI results when there is inadequate oxygen availability due to poor supply (pathological hypoxia) or abnormal tissue oxygen use and metabolism (dysoxia).

Article Synopsis
  • The rise of uterine isthmocele, tied to increasing cesarean section rates, affects about 60% of women with cesarean histories, leading to its classification as cesarean scar disorder (CSD).
  • Diagnosis is achievable through various imaging techniques, and management may involve either pharmacological or surgical options.
  • Surgical treatments, such as hysteroscopic resection, laparoscopic, and vaginal methods, vary in effectiveness and complications, with hysteroscopic treatment being the safest, although decisions should be tailored to individual patient factors, particularly residual myometrial thickness (RMT).
