Although the clinical importance of esophagogastric junction (EGJ) cancer is being increasingly recognized, its definition and treatment strategies vary considerably across regions. Recently, new concepts such as the gastroesophageal junction zone have been proposed for classification of EGJ cancer. Moreover, EGJ adenocarcinoma has been shown to possess a heterogeneous molecular profile consisting of both esophageal- and gastric-like phenotypes, indicating the need for EGJ-specific therapeutic strategies.Although international clinical practice guidelines for EGJ cancer have been published, substantial regional differences remain. This review aimed to summarize recent updates on the biological characteristics and management of EGJ cancers. Trials such as TIME and MIRO have demonstrated that minimally invasive surgery (MIS) reduces postoperative complications and improves the early postoperative quality of life. More recently, the MONET trial showed that MIS is not inferior to open esophagectomy in terms of long-term oncological outcomes, and the REVATE trial demonstrated the advantages of robot-assisted surgery over thoracoscopic approaches. Perioperative treatment strategies also differ across regions. Western guidelines recommend 5-fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT)-based perioperative chemotherapy, as supported by the FLOT4 and ESOPEC trials, whereas Asian studies, such as RESOLVE and PRODIGY, have demonstrated the efficacy of docetaxel, oxaliplatin, and S-1 or S-1 plus oxaliplatin regimens. The application of immune checkpoint inhibitors is also evolving; although KEYNOTE-585 did not show a survival advantage, the MATTERHORN trial demonstrated that durvalumab plus FLOT significantly improved event-free survival, establishing a new emerging global standard. Future directions include redefining EGJ classification, implementing molecular-guided treatment selection, advancing organ-preserving strategies, and optimizing perioperative immunochemotherapy.

Purpose: Gastric neoplasia is a common manifestation of familial adenomatous polyposis (FAP). This study aimed to elucidate the clinical characteristics, endoscopic features including fundic gland polyposis (FGPsis), and treatment outcomes of gastric neoplasms (GNs) in patients with FAP. Materials and Methods: A total of 35 patients diagnosed with FAP, including nine patients from four pedigrees who underwent esophagogastroduodenoscopy (EGD), were investigated regarding patient characteristics, GN morphology, and treatment outcomes. Results: Twenty-one patients (60.0%) had 38 GNs; 33 (86.8%) and 5 (13.2%) were histologically diagnosed with adenocarcinoma and adenoma, respectively. There were no specific patient characteristics related to GNs.Nodule-type GNs were more prevalent in patients with FGP than without (52.2% vs. 0.0%, P=0.002) in the upper body of the stomach. Conversely, depressed-type GNs were fewer in patients with FGPsis than in those without (13.0% vs. 73.3%, P<0.001). Slightly elevated-type GNs were observed in both groups (34.8% vs. 20.0%, P=0.538). Even within pedigrees, the background gastric mucosa and types of GNs varied. In total, 24 GNs were treated with endoscopic submucosal dissection (ESD) and eight with endoscopic mucosal resection (EMR). EMR was selected for GNs with FGPsis because of the technical difficulty of ESD, resulting in a lower en bloc resection rate (62.5% vs. 100%, P=0.014). Conclusions Our study indicates the necessity of routine EGD surveillance in patients diagnosed with FAP. Notably, the morphology and location of GNs differed between patients with and without FGPsis. Endoscopic treatment and outcomes require more attention in cases of FGPsis.

OBJECTIVE: Rikkunshito, an herbal medicine, is widely prescribed in Japan for the treatment of anorexia and functional dyspepsia, and has been reported to recover reductions in food intake caused by cisplatin. We investigated whether rikkunshito could improve chemotherapy-induced nausea and vomiting (CINV) and anorexia in patients treated with cisplatin. METHODS: Patients with uterine cervical or corpus cancer who were to receive cisplatin (50 mg/m² day 1) and paclitaxel (135 mg/m² day 0) as first-line chemotherapy were randomly assigned to the rikkunshito group receiving oral administration on days 0–13 with standard antiemetics, or the control group receiving antiemetics only. The primary endpoint was the rate of complete control (CC: no emesis, no rescue medication, and no significant nausea) in the overall phase (0–120 hours). Two-tailed p<0.20 was considered significant in the planned analysis. RESULTS: The CC rate in the overall phase was significantly higher in the rikkunshito group than in the control group (57.9% vs. 35.3%, p=0.175), as were the secondary endpoints: the CC rate in the delayed phase (24–120 hours), and the complete response (CR) rates (no emesis and no rescue medication) in the overall and delayed phases (63.2% vs. 35.3%, p=0.095; 84.2% vs. 52.9%, p=0.042; 84.2% vs. 52.9%, p=0.042, respectively), and time to treatment failure (p=0.059). Appetite assessed by visual analogue scale (VAS) appeared to be superior in the rikkunshito group from day 2 through day 6. CONCLUSION: Rikkunshito provided additive effect for the prevention of CINV and anorexia.

Chronic encapsulated intracerebral hematoma (CEIH) is a rare cerebrovascular disease that behaves as a slowly expanding lesion with a gradual onset. It is well established that CEIH is associated with arteriovenous malformations; however, CEIH associated with cavernous malformation (CM) is extremely rare. We herein report a case of CEIH associated with CM, and discuss its pathogenesis. A 12-year-old female was admitted to our hospital because of a one week history of progressive headache and nausea. Brain computed tomography scan and magnetic resonance imaging showed an intracerebral hematoma surrounded by edema in the right frontal lobe. One week later, her headache and nausea worsened, and a brain computed tomography scan revealed the enlargement of hematoma. A right frontal craniotomy was performed. The capsule, mass, and hematoma were totally removed. Histological examination confirmed the diagnosis of CEIH associated with CM. Immunohistochemical analysis revealed increased expression of vascular endothelial growth factor (VEGF) and the VEGF receptor-1 in the endothelium and fibroblasts. Our findings suggest that the activated VEGF pathway might have positively contributed to development of CEIH in the present patient.

Hypertrophic pachymeningitis is an uncommon disorder that causes a localized or diffuse thickening of the dura mater. Recently, the possibility that IgG4-related sclerosing disease may underlie some cases of intracranial hypertrophic pachymeningitis has been suggested. We herein report the tenth case of IgG4-related intracranial hypertrophic pachymeningitis and review the previous literature. A 45-year-old male presented with left-sided focal seizures with generalization. Magnetic resonance imaging (MRI) revealed a diffuse thickening and enhancement of the right convexity dura matter and falx with focal nodularity. The surgically resected specimens exhibited the proliferation of fibroblast-like spindle cells and an infiltration of mononuclear cells, including predominantly plasma cells. The ratio of IgG4-positive plasma cells to the overall IgG-positive cells was 45% in the area containing the highest infiltration of plasma cells. On the basis of the above findings, IgG4-related sclerosing disease arising from the dura mater was suspected. IgG4-related sclerosing disease should be added to the pachymeningitis spectrum.

Purpose: The aim of this study was to clarify the factors contributing to the evaluation of perceived care in inpatient palliative care services from the aspect of informal caregiver after their loss of the patient to cancer. Method: A questionnaire was mailed to 9,684 bereaved subjects who had lost family members at one of 103 palliative care units in Japan to evaluate their sociodemographic characteristics and the evaluation of perceived care. An institution survey was performed to collect organization-related variables. The evaluation of perceived care was rated by the Care Evalutaion Scale (CES), the Good Death Inventory (GDI) and single item of overall satisfation. Result: A total of 5,810 responses were analyzed (response rate＝60％). Uni-variate and multivariate analysis was performed to clarify the determinants of each scale. Significant determinants of the score in the evaluation of care identified were: the rate of private room (100％), independent facility, palliative care physician being night-time duty, the number of nurses at night (＞0.1 per bed), sending a letter to every bereaved family, holding a memorial services for every bereaved family and having a religious background. Conclusion: In conclusion, the evaluation of palliative care from the aspect of informal caregiver was influenced by various organization-related variables.

The objective of this study was to assess the possibility of developing a clinical minimally invasive and standardized method to evaluate the relationship between the microstructure of the jaw bone and systemic bone turnover. For this purpose, we performed standardized bone biopsy of the alveolar bone, and compared the 3D bone microstructure using micro-computed tomography (micro-CT) with bone mineral density (BMD) of the lumbar spine and biochemical markers of bone turnover. We evaluated a total of 9 samples taken from 6 patients by standardized biopsy using a trephine bur. BMD was evaluated using dual energy X-ray absorptiometry (DXA). Regarding the biochemical markers of bone turnover, serum bone-specific alkaline phosphatase (BAP) and serum osteocalcin (OC) were used as bone formation markers, and urinary cross-linked N-telopeptides of type I collagen (NTx) and urinary deoxypyridinoline (DPD) were selected as bone resorption markers. We scanned micro-CT images of these samples. Bone volume fraction (BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N), trabecular spacing (Tb.Spac), fractal dimension, trabecular bone pattern factor (TBPf) and node-strut (Nd.Nd/TV, TSL/TV) were measured. Regarding the correlations between the parameters of bone microstructures, TB/TV, Tb.N, fractal dimension, and node-strut seemed to be positively correlated and Tb.Spac and TBPf seemed to be negatively correlated with each other, but Tb.Th seemed to have a low correlation with other parameters. OC and/or BAP showed a significantly high correlation with many structural parameters (p<0.05%). In conclusion, some microstructural parameters may change according to the systemic bone turnover.
