Article Abstract
Background: Current guidelines recommend pelvic lymphadenectomy (PLND) for patients with pelvic lymph node metastasis and special state. However, these data and recommendations do not distinguish the role of PLND in different patient groups and confirm the final benefits. The aim of this study was to confirm the efficacy of pelvic lymphadenectomy (PLND) for the different groups of patients.
Methods: Data obtained from 7 centers were retrospectively analyzed. Of the patients, 190 pN2-3 penile carcinoma patients confirmed by bilateral inguinal lymph node excision were included in this study. Sixty-nine and 121 of these patients did and did not undergo bilateral PLND, respectively. The baseline differences from the patients were matched by propensity score analysis.
Results: In this study, the Kaplan-Meier estimated disease-specific survival (DSS) was not significantly different between the PLND and no-PLND groups (P = 0.796). According to the propensity score matching for T stage, N stage, grade, adjuvant therapies, and lymph node stage (number of inguinal lymph node metastasis and extranodal extension), 48 patients were selected for each group. Among the pN2 patients, the PLND group showed higher DSS rates than the no-surgery group (P = 0.030). However, even after matching, survival did not differ between the PLND and no-PLND patients among all patients (P = 0.609) and pN3 patients (P = 0.417) with comparable DSS.
Conclusion: Bilateral PLND may improve survival in pN2 patients. Men with pN3 may not benefit from bilateral PLND.

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.
