Objective: The aim of this study was to investigate the expression of transforming growth factor-beta1 (TGF-beta1) and its signaling pathway molecules in oral squamous cell carcinoma (OSCC) and analyze the association between these factors and genesis and metastasis of OSCC.
Methods: The express of TGF-beta1, TbetaRI, TbetaRII and Smad4, a pivotal downstream molecule of its signaling, in 10 normal oral mucosa tissues and 108 OSCC was detected by SP immunohistochemistry, and thier correlation with genesis and metastasis of OSCC were assessed.
Results: The expressions of TbetaRII and Smad4 were lower in the tumors (34.3%, 38.9%) than those in the normal oral epithelium (80.0%, 100.0%, P < 0.05). The positive expression rates of TGF-beta1 and TbetaRI in the normal oral epithelium and OSCC were not significantly different (P > 0.05). There was an inverse correlation between TGF-beta1, Smad4, TbetaRII, TbetaRI expression and clinical stages (P < 0.01). The expression of TGF-beta1 was related with histological differentiation and tumor localization (P < 0.05). There was a relationship beteween Smad4 expression and histological differentiation and lymph node metastasis (P < 0.05). The expression of TbetaRII in the samples with lymph node metastasis was less than that in the ones without lymph node metastasis (P < 0.01), although there was no association between expression of TbetaRII and lymph node metastasis status.
Conclusion: There is an important relationship between the abnormal TGF-beta1/Smad4 signal pathway and genesis and development of OSCC, while the low expressed Smad4 and TbetaRII may promote the metastasis of OSCC.

Background: T follicular helper (TFH) cell lymphoma is complex, and we hope to provide a new perspective for its diagnosis.
Methods: We analysed the immunophenotypes of 89 mature T-cell lymphomas, including 52 nodal lymphomas of TFH origin, as well as 32 benign lymph node samples and 30 healthy bone marrow samples, by flow cytometry (FCM).
Results: Among pan-T cell markers, CD4CD5CD3 is the typical pattern that distinguishes TFH lymphoma from other T-cell lymphomas.

Background: Previous studies indicated that over-dissection of lymph nodes might impair the efficacy of immunotherapy. This study aims to explore the prognostic value of ypN + status and the impact of lymph node dissection (LND) on survival after neoadjuvant immunochemotherapy (NICT) for esophageal squamous cell cancer (ESCC).
Methods: This double-center retrospective study enrolled 206 consecutive ESCC patients who underwent NICT followed by esophagectomy between 2018 and 2024.

Background: Minimally invasive pancreaticoduodenectomy (MIPD) is used more commonly, but this surge is mostly based on observational data. This meta-analysis aimed to compare the short-term outcomes between MIPD and open pancreaticoduodenectomy (OPD) using data collected from randomized controlled trials (RCTs).
Methods: We searched PubMed, Cochrane Library, Embase, and Web of Science databases for RCTs comparing MIPD and OPD published before December 10, 2024.

Introduction And Aim: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare neoplasms originating in neuroendocrine cells from the gastric mucosa and submucosa, small intestine, large intestine, rectum, and pancreas. Our aim was to describe their histopathologic, endoscopic, and clinical characteristics and the experience with these tumors at a tertiary care hospital center in the Colombian Southwest.
Materials And Methods: A retrospective, analytic, observational, and descriptive study included 93 patients diagnosed with GEP-NETs, within the time frame of 2018 and 2022.

Kawasaki disease (KD) is an acute vasculitis of childhood, which can lead to complications affecting multiple organ systems. Protein-losing enteropathy (PLE) is an extremely rare complication of KD, characterised by excessive protein loss through the gastrointestinal tract, leading to hypoalbuminaemia, oedema and immune dysfunction. We report a case of an early childhood boy with intravenous immune globulin (IVIG)-resistant incomplete KD who developed PLE.
