Background And Aim: To evaluate the clinical value of multiband mucosectomy (MBM) for the treatment of squamous intraepithelial neoplasia of the esophagus.
Methods: A total of 51 lesions located at esophagus from 43 patients were treated with MBM, among which 11 were diagnosed as middle-grade intraepithelial neoplasia, 25 as high-grade intraepithelial neoplasia, and 15 as early esophageal cancer pathologically. Primary end-points were the rate of complete endoscopic resection and the mean operation time; the second end-points were the postoperative local recurrence rate and acute plus early complications. The histopathological results were compared between pre-MBM biopsy and MBM specimens. All patients were followed up endoscopically.
Results: A total of 52 MBM procedures with 180 resections were performed in 43 patients. The complete endoscopic resection was achieved in 92.3% (95% confidence interval [CI] 81.8-96.9%). The sizes of the lesions ranged from 10 × 8 mm to 25 × 23 mm. The mean operation time is 37 ± 5 min. The operative acute bleeding complication was 7.6% (95% CI 3-18.1%); no perforations occurred. Early complications consisted of delayed bleeding (one patient 1.9%; 95% CI 0.3-10.1%) and slight esophageal stenosis (one patient). The histopathological diagnosis of 26 cases (51%) was consistent between biopsy and MBM samples, while 20 lesions exhibited higher grade dysplasia. The local recurrence rate was 6.9% (3/43) at 1 year, 9.3% (4/43) at 2 years, and 9.3% at 2.5 years. No death occurred during follow-up.
Conclusions: MBM is a safe and effective technique for the treatment of early esophageal cancer and precancerous lesions.

Background: Recent advancements in artificial intelligence (AI) have significantly enhanced the capabilities of endoscopic-assisted diagnosis for gastrointestinal diseases. AI has shown great promise in clinical practice, particularly for diagnostic support, offering real-time insights into complex conditions such as esophageal squamous cell carcinoma.
Case Summary: In this study, we introduce a multimodal AI system that successfully identified and delineated a small and flat carcinoma during esophagogastroduodenoscopy, highlighting its potential for early detection of malignancies.

Purpose: Human papillomavirus (HPV) infection is the major cause of (pre)malignant cervical lesions. We previously demonstrated that Vvax001, a replication-incompetent Semliki Forest virus (SFV) vaccine encoding HPV type 16 (HPV16) E6 and E7, induced potent anti-E6 and -E7 cytotoxic T-cell responses. Here, we investigated the clinical efficacy of Vvax001 in patients with HPV16-positive cervical intraepithelial neoplasia grade 3 (CIN3).

Background: Breast conserving surgery (BCS) with partial breast reconstruction (PBR) results in less morbidity, better cosmetic outcomes, and improved patient satisfaction compared to mastectomy. Perforator flap reconstruction can attenuate defects prone to breast deformity after BCS. Usually, postoperative drains and inpatient admission are part of this treatment.

A low oxygen level in solid tumors is behind the modern concept of selective chemotherapy by hypoxia-activated prodrugs, such as heteroleptic complexes of transition metals (cobalt(III), iron(III) or platinum(IV)) with bi- or tetradentate ligands and an anticancer drug molecule as a co-ligand. A series of new cobalt(III) complexes [Co(LR)(esc)]ClO with esculetin (6,7-dihydroxycoumarin) and 2,2'-bipyridines (2,2'-bipy) functionalized by different substituents R were probed in the hypoxia-activated delivery of this model anticancer drug. Their combined study by cyclic voltammetry and NMR spectroscopy allowed identifying linear correlations of the electrochemical reduction potentials and the rate of the hypoxia-activated dissociation of [Co(LR)(esc)]ClO with the Hammett constants of the substituents in 2,2'-bipy ligands.

Background: Altered glucose metabolism is a critical characteristic from the beginning stage of esophageal squamous cell carcinoma (ESCC), and the phenomenon is presented as a pink-color sign under endoscopy after iodine staining. Therefore, calculating the metabolic score based on the glucose metabolic gene sets may bring some novel insights, enabling the prediction of prognosis and the identification of treatment choices for ESCC.
Methods: A total of 8, 99, and 140 individuals from The Gene Expression Omnibus database, The Cancer Genome Atlas database, and the Memorial Sloan Kettering Cancer Center, respectively, were encompassed in the investigation.
