BACKGROUND Sinonasal undifferentiated carcinoma(SNUC) is a rare aggressive tumor that is often unresectable. Optimal treatment for patients with unresectable,locally advanced SNUC(LA-SNUC) has not been established,and the patient outcome remains poor. We report two cases of unresectable LA-SNUC in which induction chemotherapy with docetaxel,cisplatin and fluorouracil(TPF) followed by radiotherapy with concurrent cisplatin(CCRT),a standard treatment option for locally advanced head and neck cancer,demonstrated promising outcomes.CASE SUMMARY A 39-year-old man presented with tearing and pain in the right eye. A biopsy of the tumor invading the sinonasal cavities,right orbit and cranial base confirmed the diagnosis of LA-SNUC. Induction TPF chemotherapy induced remarkable tumor shrinkage and rapidly improved the symptoms. He subsequently received CCRT and achieved complete remission of the disease. The other case is a 21-year-old man who presented with worsening vision. The unresectable tumor involving the nasal septum and cranial base was pathologically diagnosed as SNUC. TPF chemotherapy followed by CCRT yielded complete remission of the disease with preserved visual function. Both patients have been disease-free for44 mo.CONCLUSION Induction TPF chemotherapy followed by CCRT may remarkably improve the outcomes in LA-SNUC patients.

BACKGROUND Other than surgery,endoscopic ultrasound-guided fine-needle aspiration(EUSFNA)is the only procedure for histologically diagnosing autoimmune pancreatitis(AIP).However,adequate specimens are difficult to obtain.Recently,more adequate specimens were reported to be obtained with EUS-FNA with a wet suction technique(WEST)than with conventional EUS-FNA.AIM To histologically diagnose AIP by EUS-FNA with a WEST.METHODS Eleven patients with possible type 1 AIP between February 2016 and August 2018 underwent EUS-FNA with a WEST(WEST group),with four punctures by 19 or 22 G needles.As a historical control,23 type 1 AIP patients who underwent no fewer than four punctures with 19 or 22 G needles were enrolled(DRY group).Patient characteristics and histological findings were compared between the two groups.RESULTS Three histopathological factors according to the International Consensus Diagnostic Criteria were significantly greater in the WEST group than the DRY group[lymphoplasmacytic infiltrate without granulocytic infiltration:9(81.8%)vs 6(26.1%),P=0.003,storiform fibrosis:5(45.5%)vs 1(4.3%),P=0.008,abundant(>10 cells/HPF)IgG4-positive cells:7(63.6%)vs 5(21.7%),P=0.026].Level 1 or level 2 histopathological findings were observed more often in the WEST group than in the DRY group[8(72.7%)vs 3(13.0%),P=0.001].CONCLUSION EUS-FNA with a WEST was more successful than standard EUS-FNA in histologically diagnosing AIP.

AIM To evaluate the efficacy of endoscopic ultrasoundguided fine needle aspiration(EUS-FNA) of pancreatic head cancer when pushing(push method) or pulling the echoendoscope(pull method).METHODS Overall, 566 pancreatic cancer patients had their first EUS-FNA between February 2001 and December 2017. Among them, 201 who underwent EUS-FNA for pancreatic head lesions were included in this study. EUS-FNA was performed by the push method in 85 patients, the pull method in 101 patients and both the push and pull methods in 15 patients. After propensity score matching(age, sex, tumor diameter, and FNA needle), 85 patients each were stratified into the push and pull groups. Patient characteristics and EUSFNA-related factors were compared between the two groups.RESULTS Patient characteristics were not significantly different between the two groups. The distance to lesion was significantly longer in the push group than in the pull group(13.9 ± 4.9 mm vs 7.0 ± 4.9 mm, P < 0.01). The push method was a significant factor influencing the distance to lesion(≥ median 10 mm)(P < 0.01). Additionally, tumor diameter ≥ 25 mm(OR = 1.91, 95%CI: 1.02-3.58, P = 0.043) and the push method(OR = 1.91, 95%CI: 1.03-3.55, P = 0.04) were significant factors contributing to the histological diagnosis of malignancy.CONCLUSION The pull method shortened the distance between the endoscope and the lesion and facilitated EUS-FNA of pancreatic head cancer. The push method contributed to the histological diagnosis of pancreatic head cancer using EUS-FNA specimens.

Compared to human vision, conventional machine vision composed of an image sensor and processor suffers from high latency and large power consumption due to physically separated image sensing and processing. A neuromorphic vision system with brain-inspired visual perception provides a promising solution to the problem. Here we propose and demonstrate a prototype neuromorphic vision system by networking a retinomorphic sensor with a memristive crossbar. We fabricate the retinomorphic sensor by using WSe2/h-BN/Al2O3van der Waals heterostructures with gate-tunable photoresponses, to closely mimic the human retinal capabilities in simultaneously sensing and processing images. We then network the sensor with a large-scale Pt/Ta/Hf O2/Ta one-transistor-one-resistor(1 T1 R) memristive crossbar,which plays a similar role to the visual cortex in the human brain. The realized neuromorphic vision system allows for fast letter recognition and object tracking, indicating the capabilities of image sensing, processing and recognition in the full analog regime. Our work suggests that such a neuromorphic vision system may open up unprecedented opportunities in future visual perception applications.

The incidence of esophagogastric junction(EGJ)adenocarcinoma has been increasing in Asian countries.Despite the recent advances in multidisciplinary treatments,EGJ adenocarcinoma remains aggressive with unfavorable outcomes.Regarding surgical strategy,EGJ adenocarcinoma arises between the esophagus and the stomach,and thus tumor cells spread through the lymphatic system both upward to the mediastinum and downward to the abdomen.Nevertheless,an optimal extent of lymphadenectomy remains controversial.Regarding drug therapy,the latest topic in gastric and EGJ adenocarcinoma is trastuzumab deruxtecan,which is an antibody-drug conjugate consisting of an anti-HER2 antibody.In addition,many clinical trials have recently demonstrated the efficacy of immune checkpoint inhibitors.Meanwhile,recent advances in sequencing technology have revealed that gastroesophageal adenocarcinoma could be categorized into four molecular subtypes:epstein-Barr virus-associated,high-level microsatellite instability,genomically stable,and chromosomal instability tumors.Furthermore,these subtypes show distinct clinical phenotypes and molecular alterations.We review the current surgical strategy and drug treatment such as molecular-targeted agents,immune checkpoint inhibitors,and molecular-subtype-based therapeutic strategies in EGJ adenocarcinoma.Clinical and molecular characteristics and response to immune checkpoint inhibitors differ among molecular subtypes.Treatment strategies based on molecular subtypes may be clinically beneficial for patients with EGJ adenocarcinoma.

BACKGROUND Pancreaticobiliary cancer(PB Ca)is a lethal disease,and a useful diagnostic marker is urgently needed.A correlation between the human microbiota and malignant gastrointestinal diseases was recently reported.AIM To investigate the efficacy of the duodenal microbiota for diagnosing PB Ca.METHODS We recruited 22 patients with benign pancreaticobiliary diseases(benign group)and 12 patients with PB Ca(malignant group).The duodenal microbiota of each patient was analyzed by the 16S rDNA terminal restriction fragment length polymorphism method.Patient characteristics,tumor markers,and relative abundances of the duodenal microbiota were compared between the benign and malignant groups.RESULTS Cancer antigen 19-9(CA19-9),Bifidobacterium,Clostridium cluster XVIII,and Prevotella levels differed significantly between the benign and malignant groups.Clostridium cluster XVIII had the greatest area under the receiver operating characteristic curve(AUC)among the four factors with respect to diagnosing PB Ca(cutoff value:3.038%;sensitivity:58.3%;specificity:95.2%;AUC:0.81).The combination of Clostridium cluster XVIII(cutoff value:3.038%)and CA19-9 Levels(cutoff value:18.8 U/mL)showed 91.7%sensitivity and 71.4%specificity for diagnosing PB Ca.CONCLUSION The duodenal microbiota may be useful for PB Ca screening.

A 57-year-old woman previously diagnosed with blue rubber bleb nevus syndrome(BRBNS) reported hematemesis. BRBNS is a rare vascular anomaly syndrome consisting of multifocal hemangiomas of the skin and gastrointestinal(GI) tract but her GI tract had never been examined. An upper gastrointestinal endoscopy revealed a large bleeding esophageal hematoma positioned between the thoracic esophagus and the gastric cardia. An endoscopic injection of polidocanol was used to stop the hematoma from bleeding. The hematoma was incised using the injectionneedle to reduce the pressure within it. Finally, argon plasma coagulation(APC) was applied to the edge of the incision. The esophageal hematoma disappeared seven days later. Two months after the endoscopic the rapy, the eso phage alulcerhealed and the hemangioma did not relapse. This rare case of a large esophageal hematoma originating from a hemangioma with BRBNS was treated using a combination of endoscopic therapy with polidocanol injection, incision, and APC.

In the human airway, the overproduction of MUC5AC mucin is a key feature of allergic asthma, and it induces airway narrowing and obstruction. The production of MUC5AC is regulated by several signals, but the mechanism is not completely understood. We investigated the effect of jabara, a citrus containing abundant flavonoids, on the regulation of MUC5AC production. When NCI-H292 human airway epithelial cells were cultured with jabara extracts, we found that the expression of Periodic acid-schiff stained mucin was suppressed with downregulated MUC5AC production. In human primary airway cells derived from asthmatic patients, MUC5AC production was also suppressed by jabara extracts. The treatment of cells with jabara extracts decreased ERK activation in NCI-H292 and in primary cells. These results show that jabara extracts contain some factors that suppress MUC5AC production and ERK activity and suggest that it will be useful for relieving asthma.
