抄録	This study evaluated the feasibility of predicting pathogenic BRCA1/2 variants in ovarian cancer using radiogenomic analysis of contrast-enhanced MRI. Twenty six patients were analyzed, including 14 with pathogenic BRCA1/2 variants and 12 without. Contrast enhanced MRI was used to generate two dimensional (2D) and three dimensional (3D) tumor segmentations. Radiomic features extracted with PyRadiomics were reduced using least absolute shrinkage and selection operator (LASSO) regression, yielding two selected features. Linear discriminant analysis (LDA) models were trained on 18 patients and tested on 8, with performance assessed using sensitivity, specificity, accuracy, and the area under the receiver operating characteristic (ROC) curve. The DeLong test compared AUCs between segmentation methods. Automated machine learning (AutoML) was performed with a training set of 20 patients and a test set of 6, with multiple performance metrics calculated. LDA achieved approximately 60% accuracy in both 2D and 3D test datasets. AUCs were 0.80 (3D) and 0.77 (2D), with no significant difference (p=0.85). AutoML identified CatBoost_BAG_L2_FULL as the optimal model, achieving accuracy above 80%. MRI-based radiogenomic analysis demonstrated moderate classification performance for identifying pathogenic BRCA1/2 variants in ovarian cancer. These preliminary findings suggest a potential role for noninvasive prediction, warranting further validation in larger cohorts.

Prognostic Value of Combined Preoperative CALLY and SII Assessment in Patients Undergoing Resection for Esophageal Squamous Cell Carcinoma

JaLCDOI	10.18926/AMO/71339

抄録	This study evaluated the prognostic significance of the C-reactive protein–albumin–lymphocyte (CALLY) index and systemic immune-inflammation (SII) index in predicting postoperative outcomes in patients with esophageal squamous cell carcinoma (ESCC). A retrospective analysis was performed on clinical data from 102 patients with ESCC who underwent surgical resection at Western Theater General Hospital of China between January 2020 and July 2023. The associations between preoperative CALLY and SII indices and relapse-free survival (RFS) and overall survival (OS) were examined. Survival curves were generated using the Kaplan–Meier method, and prognostic factors were identified using Cox proportional hazards regression analysis. Patients with a high CALLY index had significantly longer RFS (HR=0.30, 95% CI: 0.13-0.71), and those with a low SII index also had significantly longer RFS (HR=2.23, 95% CI: 1.12-4.41). Similarly, patients with a high CALLY index had significantly longer OS (HR=0.27, 95% CI: 0.13-0.55), and those with a low SII index had significantly longer OS (HR=2.27, 95% CI: 1.09-4.71). When patients were stratified into four groups, the low-CALLY–high-SII group showed significantly shorter RFS than the high-CALLY–low-SII group (HR=0.26, 95% CI: 0.11-0.61; p=0.013), and OS was also significantly worse in the low-CALLY–high-SII group (HR=0.22, 95% CI: 0.09-0.54; p=0.016). Univariate Cox regression analysis identified both CALLY and SII as significant prognostic factors. In multivariate analysis, the CALLY index and N stage were independently associated with RFS, whereas only tumor size remained independently associated with OS. The combined assessment of preoperative CALLY and SII indices may be useful for prognostic stratification in patients with ESCC undergoing upfront surgical resection. It may help identify high-risk patient subgroups with distinct survival outcomes, thereby providing a potential rationale for stratifying postoperative surveillance and tailoring individualized adjuvant strategies, although validation in larger prospective cohorts is warranted.

Artificial Intelligence-Assisted Peroral Cholangioscopy for the Diagnosis and Management of Biliary Strictures: Current Evidence and Future Directions

抄録	Peroral cholangioscopy (POCS) enables direct intraductal visualization and targeted biopsies for indeterminate biliary strictures. However, its diagnostic performance remains operator-dependent and is limited by sampling error. As artificial intelligence (AI) has rapidly advanced in gastrointestinal endoscopy, AI-assisted cholangioscopy has progressed from proof-of-concept image classification to multicenter validation, feature detection, and real-time application. Recent studies using digital single-operator cholangioscopy have reported diagnostic accuracy comparable to that of experts in differentiating malignant from benign strictures, and feature-based approaches can automatically detect tumor vessels and other key visual characteristics. Beyond classification, generative models may enhance mucosal and margin visualization through virtual chromoendoscopy, potentially improving lesion-margin assessment. Furthermore, new models compatible with multiple systems are emerging to address device heterogeneity, which is a key barrier to routine practice. This review summarizes the current evidence on AI-assisted POCS, discusses practical considerations for clinical translation, and highlights future directions, including real-time integration and multimodal decision support.

Spinous Process Plate Fixation Alone for an AO Spine Osteoporotic Fracture (OF) 5 Diffuse Idiopathic Skeletal Hyperostosis (DISH)-Associated Thoracolumbar Fracture in a Nonagenarian

抄録	Diffuse idiopathic skeletal hyperostosis (DISH) predisposes the spine to highly unstable fractures because of long lever-arm biomechanics. Unstable injuries, including AO Spine Osteoporotic Fracture (OF) type 5, are typically treated with long-segment posterior instrumentation; however, pedicle-screw fixation may be infeasible in very elderly patients with severe osteoporosis, critically narrow pedicles, and/or significant comorbidities. A 93-year-old Japanese woman presented with severe back pain without apparent trauma. Computed tomography (CT) revealed a T12 fracture with DISH, classified as OF5. The pedicles were critically narrow (3.7-4.1 mm), and dual-energy X-ray absorptiometry confirmed severe osteoporosis. Because conventional pedicle-screw fixation was considered technically unsafe and excessively invasive, limited posterior stabilization was performed using a single spinous process plate spanning T10-L1. The operative time was 48 min and the estimated blood loss was 10 ml. Immediate postoperative CT confirmed appropriate implant positioning and maintained alignment. At the 1-year follow-up, CT demonstrated solid bony union with preserved alignment and no implant failure; the patient had remained pain-free and ambulatory. This case demonstrates that spinous process-plate fixation can be a minimally invasive salvage option for carefully selected very-elderly patients with DISH when pedicle-screw instrumentation is not feasible.

抄録	Primary hyperparathyroidism (pHPT) is typically caused by a parathyroid adenoma, although some cases arise from ectopic glands. Accurate preoperative localization is essential for guiding surgical strategy, particularly for mediastinal lesions. We report successful video-assisted thoracoscopic surgery (VATS) for an upper mediastinal parathyroid adenoma. A 68-year-old woman was referred for hypercalcemia during evaluation for recurrent ureteral stones. Laboratory tests revealed elevated serum calcium (13.2 mg/dl) and intact parathyroid hormone (iPTH) levels (266 pg/ml). Contrast-enhanced computed tomography, magnetic resonance imaging, and 99mTc-methoxyisobutylisonitrile scintigraphy identified a 20-mm mass adjacent to the right esophageal wall. VATS was performed due to the tumor’s mediastinal location. The lesion was resected with intraoperative nerve monitoring (IONM) to avoid recurrent laryngeal nerve damage. Postoperatively, iPTH and calcium levels rapidly normalized. Transient hypocalcemia and mild hoarseness occurred but resolved with calcium supplementation and conservative management. Pathological examination confirmed a parathyroid adenoma without malignancy. VATS offers a safe and minimally invasive approach for upper mediastinal parathyroid adenomas. IONM and vigilant calcium management are crucial for minimizing these complications. This case highlights the importance of comprehensive imaging, surgical planning, and postoperative care in managing upper mediastinal pHPT.
