Endoscopic mucosal resection for high-grade dysplasia and intramucosal carcinoma in Barrett's esophagus: An Italian experience

AIM： To evaluate endoscopic mucosal resection （EMR） in patients with high-grade dysplasia （HGD） and/or intramucosal cancer （IMC） in Barrett＇s esophagus （BE）. METHODS： Between June 2000 and December 2003, 39 consecutive patients with HGD （35） and/or IMC （4） underwent EMR. BE 〉30 mm was present in 27 patients. In three patients with short segment BE （25.0%）, HGD was detected in a normal appearing BE. Lesions had a mean diameter of 14.8＋10.3 ram. Mucosal resection was carried out using the cap method. RESULTS： The average size of resections was 19.7± 9.4×14.6＋8.2 mm. Histopathologic assessment postresection revealed 5 low-grade dysplasia （LGD） （12.8%）, 27 HGD （69.2%）, 2 IMC （5.1%）, and 5 SMC （-12.8%）. EMR changed the pre-treatment diagnosis in 10 patients （25.6%）. Three patients with SMC underwent surgery. Histology of the surgical specimen revealed 1 TON0 and 2 TIN0 lesions. The remaining two patients were cancer free at 32.5 and 45.6 mo, respectively. A metachronous lesion was detected after 25 mo in one patient with HGD. Intra-procedural bleeding, controlled at endoscopy, occurred in four patients （10.3%）. After a median follow-up of 34.9 mo, all patients remained in remission. CONCLUSION： In the medium term, EMR is effective and safe to treat HGD and/or IMC within BE and is a valuable staging method. It could become an alternative to surgery.

Barrett's esophagus with high-grade dysplasia:Focus on current treatment options

High-grade dysplasia(HGD) in Barrett's esophagus(BE) is the critical step before invasive esophageal adenocarcinoma.Although its natural history remains unclear,an aggressive therapeutic approach is usually indicated.Esophagectomy represents the only treatment able to reliably eradicate the neoplastic epithelium.In healthy patients with reasonable life expectancy,vagal-sparing esophagectomy,with associated low mortality and low early and late postoperative morbidity,is considered the treatment of choice for BE with HGD.Patients unfit for surgery should be managed in a less aggressive manner,using endoscopic ablation or endoscopic mucosal resection of the entire BE segment,followed by lifelong surveillance.Patients eligible for surgery who present with a long BE segment,multifocal dysplastic lesions,severe reflux symptoms,a large fixed hiatal hernia or dysphagia comprise a challenging group with regard to the appropriate treatment,either surgical or endoscopic.

Synchronous but separate neuroendocrine tumor and high-grade dysplasia/adenoma of the gall bladder:A case report

BACKGROUND Gall bladder neuroendocrine tumors(GB-NETs)are rare,accounting for less than 0.5%of all NETs.They usually lack specific symptoms and are difficult to diagnose preoperatively.In most cases,GB-NETs are incidentally found after cholecystectomy for large polyps or cholelithiasis,causing acute or chronic cholecystitis.The coexistence of GB-NET and GB adenocarcinoma is very rare.CASE SUMMARY We report a case of synchronous but separate GB-NET and adenoma with high-grade dysplasia in a patient who had undergone surgery for a progressively growing GB polypoid lesion.To the best of our knowledge,simultaneous separation of NETs and cancer in the GB has not been reported.CONCLUSION Coexistent GB carcinoid tumor and adenocarcinoma is rare.A surveillance program is needed for these large GB polyps.

Application of convolutional neural network-based endoscopic imaging in esophageal cancer or high-grade dysplasia: A systematic review and meta-analysis

BACKGROUND Esophageal cancer is the seventh-most common cancer type worldwide,accounting for 5%of death from malignancy.Development of novel diagnostic techniques has facilitated screening,early detection,and improved prognosis.Convolutional neural network(CNN)-based image analysis promises great potential for diagnosing and determining the prognosis of esophageal cancer,enabling even early detection of dysplasia.METHODS PubMed,EMBASE,Web of Science and Cochrane Library databases were searched for articles published up to November 30,2022.We evaluated the diagnostic accuracy of using the CNN model with still image-based analysis and with video-based analysis for esophageal cancer or HGD,as well as for the invasion depth of esophageal cancer.The pooled sensitivity,pooled specificity,positive likelihood ratio(PLR),negative likelihood ratio(NLR),diagnostic odds ratio(DOR)and area under the curve(AUC)were estimated,together with the 95%confidence intervals(CI).A bivariate method and hierarchical summary receiver operating characteristic method were used to calculate the diagnostic test accuracy of the CNN model.Meta-regression and subgroup analyses were used to identify sources of hetero-geneity.RESULTS A total of 28 studies were included in this systematic review and meta-analysis.Using still image-based analysis for the diagnosis of esophageal cancer or HGD provided a pooled sensitivity of 0.95(95%CI:0.92-0.97),pooled specificity of 0.92(0.89-0.94),PLR of 11.5(8.3-16.0),NLR of 0.06(0.04-0.09),DOR of 205(115-365),and AUC of 0.98(0.96-0.99).When video-based analysis was used,a pooled sensitivity of 0.85(0.77-0.91),pooled specificity of 0.73(0.59-0.83),PLR of 3.1(1.9-5.0),NLR of 0.20(0.12-0.34),DOR of 15(6-38)and AUC of 0.87(0.84-0.90)were found.Prediction of invasion depth resulted in a pooled sensitivity of 0.90(0.87-0.92),pooled specificity of 0.83(95%CI:0.76-0.88),PLR of 7.8(1.9-32.0),NLR of 0.10(0.41-0.25),DOR of 118(11-1305),and AUC of 0.95(0.92-0.96).CONCLUSION CNN-based image analysis in diagnosing esophageal cancer and HGD is an excellent diagnostic method with high sensitivity and specificity that merits further investigation in large,multicenter clinical trials.

Management of esophageal mucosa with high-grade dysplasia

Objective:Early detection and treatment in patients with esophageal cancer is the most effective way to improve the prognosis. Patients with high-grade dysplasia(HGD) in esophageal mucosa might be involved with early esophageal cancer,but the management of the disease is controversial. The purpose of our study was to explore the management of esophageal mucosa with HGD. Methods:We retrospectively analyzed 10 patients with HGD in esophageal mucosa,who underwent esophagectomy in Cancer Hospital of Fudan University from 1999 to 2006. The surgical approach,postoperative morbidity,in-hospital complications and pathological results of the patients were analyzed. Basing on our data together with other studies,we aimed at looking for an appropriate management for patients with HGD. Results:Of the 10 patients who received esophagectomy,the pathological results showed that 2(20%) cases were in situ carcinoma and 8(80%) cases were invasive cancer with no regional lymph nodes involved. 30-day mortality was 0. One patient experienced cervical anastomotic leakage,but healed in 2 weeks. There was no pulmonary complication. Conclusion:Most patients with HGD actually have occult carcinoma. High percentage of patients with HGD would develop into cancer during their lifetime. Esophagectomy is now a selective approach for the treatment of the patients with HGD.

Photodynamic therapy for high-grade dysplasia of bile duct via a choledochoscope

When a distal common bile duct neoplasm is at the stage of carcinoma in situ or high-grade dysplasia,it is difficult for the surgeon to decide whether to perform pancreaticoduodenectomy.Here we describe a patient with a progressive dysplastic lesion in the common bile duct,which developed from moderate-high to highgrade dysplasia in approximately 2 mo.The patient refused major surgery.Therefore,endoscopic-assisted photodynamic therapy was performed.The result at follow-up using a trans-T-tube choledochoscope showed that the lesion was completely necrotic.This report is the first to describe the successful treatment of highgrade dysplasia of the distal bile duct using photodynamic therapy via a choledochoscope.

Esophageal resection for high-grade dysplasia and intramucosal carcinoma: When and how?

High-grade dysplasia (HGD) and intramucosal carcinoma (IMC) in the setting of Barrett’s esophagus have traditionally been treated with esophagectomy. However, with the advent of endoscopic mucosal resection and endoscopic ablative therapies, endoscopic therapy at centers with expertise is now an established treatment of Barrett’s-esophagus-related neoplasia, including HGD and IMC. Esophagectomy is today reserved for more selected cases with submucosal invasion, evidence for lymph node metastasis, or unsuccessful endoscopic therapy.

Role of pancreatic juice cytology in diagnosis of high-grade pancreatic intraepithelial neoplasia

High-grade pancreatic intraepithelial neoplasia is a challenging diagnosis and itdoes not exhibit mass lesions. It is suspected based on changes in the mainpancreatic duct in magnetic resonance cholangiopancreatography. Sometimesonly an unclear duct shows in magnetic resonance cholangiopancreatographywith no focal strictures and upstream dilatation of the main pancreatic duct. Serialpancreatic juice cytology is valuable in diagnosis of those patients.

Long-term outcomes of endoscopic submucosal dissection for high-grade dysplasia and early-stage carcinoma in the colorectum

Background:Colorectal carcinomas(CRCs)arise from premalignant precursors in an adenoma-carcinoma sequence,in which adenoma with high-grade dysplasia(HGD)and early-stage carcinoma are defined as advanced neoplasia.A limited number of studies have evaluated the long-term outcomes of endoscopic submucosal dissection(ESD)for advanced colorectal neoplasia.This study aimed to assess the efficacy and safety of ESD for advanced colorectal neoplasia as well as the long-term outcomes,including local recurrence and metastasis.Methods:We analyzed data collected from 610 consecutive patients with 616 advanced colorectal neoplasia lesions treated with ESD between January 2007 and December 2013.Clinical,endoscopic,and histological data were col-lected over a median follow-up period of 58 months to determine tumor stage and type,resection status,complica-tions,tumor recurrence,and distant metastasis.Results:The overall rates of en bloc resection,histological complete resection,and major complications were 94.3%,89.4%,and 2.3%,respectively.Hybrid ESD was an independent factor of piecemeal resection.Tumor location in the colon was associated with increased risk of ESD-related complications.During the follow-up period,all patients remained free of metastasis.However,local recurrence occurred in 4 patients(0.8%);piecemeal resection was a risk factor.Conclusions:ESD is effective and safe for resection of advanced colorectal neoplasia,with a high en bloc resection rate and favorable long-term outcomes.ESD is indicated for the treatment of HGD and early-stage CRC to obtain cura-tive resection and reduce local recurrence rate.

High-grade pancreatic intraepithelial neoplasia diagnosed based on changes in magnetic resonance cholangiopancreatography findings:A case report

BACKGROUND High-grade pancreatic intraepithelial neoplasia(PanIN)exhibits no mass and is not detected by any examination modalities.However,it can be diagnosed by pancreatic juice cytology from indirect findings.Most previous cases were diagnosed based on findings of a focal stricture of the main pancreatic duct(MPD)and caudal MPD dilatation and subsequent pancreatic juice cytology using endoscopic retrograde cholangiopancreatography(ERCP).We experienced a case of high-grade PanIN with an unclear MPD over a 20-mm range,but without caudal MPD dilatation on magnetic resonance cholangiopancreatography(MRCP).CASE SUMMARY A 60-year-old female patient underwent computed tomography for a follow-up of uterine cancer post-excision,which revealed pancreatic cysts.MRCP revealed an unclear MPD of the pancreatic body at a 20-mm length without caudal MPD dilatation.Thus,course observation was performed.After 24 mo,MRCP revealed an increased caudal MPD caliber and a larger pancreatic cyst.We performed ERCP and detected atypical cells suspected of adenocarcinoma by serial pancreatic juice aspiration cytology examination.We performed a distal pancreatectomy and obtained a histopathological diagnosis of high-grade PanIN.Pancreatic parenchyma invasion was not observed,and curative resection was achieved.CONCLUSION High-grade Pan-IN may cause MPD narrowing in a long range without caudal MPD dilatation.

Bulk geochemistry,Rb-Sr,Sm-Nd,and stable O-H isotope systematics of the Metzimevin high-grade iron ore deposit,Mbalam iron ore district,southern Cameroon

Bulk geochemistry,Sr,Nd,and O-H isotope systematics are reported for the first time on banded iron formation(BIF)-hosted high-grade iron ore at the northwestern segment of Congo Craton(CC).Located in Mbalam iron ore district,Southern Cameroon,Metzimevin iron ore deposit is a hematite-magnetite BIF system,dominated by SiO_(2)+Fe_(2)O_(3)(97.1 to 99.84 wt%),with low concentrations of clastic elements e.g.,Al_(2)O_(3),TiO_(2),and HFSE,depicting a nearly pure chemical precipitate.The REE+Y signature of the iron deposit displays strong positive Eu anomaly,strong negative Ce anomaly,and chondritic to superchondritic Y/Ho ratios,suggestive of formation by mixed seawater-high temperature hydrothermal fluids in oxidising environment.The^(87)Sr/^(86)Sr ratios of the BIF are higher than the maximum^(87)Sr/^(86)Sr evolution curves for all Archean reservoirs(bulk silicate earth,Archean crust and Archean seawater),indicating involvement of continentally-derived components during BIF formation and alteration.TheƐ_(Nd)(t)(+2.26 to+3.77)and Nd model age indicate that chemical constituents for the BIF were derived from undifferentiated crustal source,between 3.002 and 2.88 Ga.The variable and diverse O and H isotope data(−1.9‰to 17.3‰and−57‰to 136‰respectively)indicate that the Metzimevin iron ore formed initially from magmatic plumes and later enriched by magmatic-metamorphic-modified meteoric fluids.Mass balance calculations indicate mineralisation by combined leaching and precipitation,with an average iron enrichment factor of>2.67 and SiO_(2)depletion factor of>0.99.This is associated with an overall volume reduction of 28.27%,reflecting net leaching and volume collapse of the BIF protholith.

Management of retroperitoneal high-grade serous carcinoma of unknown origin:A case report

BACKGROUND Retroperitoneal high-grade serous carcinoma(HGSC)of unknown origin is a sporadic tumor that can originate from ovarian cancer.Herein,we report the case of a woman with retroperitoneal HGSC of unknown origin and describe how she was diagnosed and treated.CASE SUMMARY A 71-year-old female presented with the tumor marker CA125 elevated to 1041.9 U/mL upon a regular health examination.Computed tomography revealed retroperitoneal lymph node enlargement.Subsequently,positron emission tomography scanning revealed lesions with increased F-18 fluorodeoxyglucose uptake at the nodes.As a result,she underwent laparoscopic lymph node resection,and pathology revealed metastatic adenocarcinoma with CK7(+),PAX8(+),WT1(+),PR(-),and p53 mutational loss of expression,indicating that the origin may be from the adnexa.The patient was admitted to our ward and underwent laparoscopic staging;however,the pathological results were negative.Under the suspicion of retroperitoneal HGSC of unknown origin,chemotherapy and targeted therapy were initiated.Tumor marker levels decreased after treatment.CONCLUSION We present a case of HGSC of unknown origin managed using retroperitoneal lymphadenectomy,staging surgery,chemotherapy,and targeted therapy.

Characteristics and risk factor analyses of high-grade intraepithelial neoplasia in older patients with colorectal polyps

BACKGROUND According to the degree of intradermal neoplasia in the colorectal exhalation,it can be divided into two grades:Low-grade intraepithelial neoplasia(LGIN)and high-grade intraepithelial neoplasia(HGIN).Currently,it is difficult to accurately diagnose LGIN and HGIN through imaging,and clinical diagnosis depends on postoperative histopathological diagnosis.A more accurate method for evaluating HGIN preoperatively is urgently needed in the surgical treatment and nursing intervention of colorectal polyps.AIM To explore the characteristics and risk factors of HGIN in older patients with colorectal polyps.METHODS We selected 84 older patients diagnosed with HGIN as the HGIN group(n=95 colonic polyps)and 112 older patients diagnosed with LGIN as the LGIN group(n=132 colonic polyps)from Shandong Provincial Hospital Affiliated to Shandong First Medical University.The endoscopic features,demographic characteristics,and clinical manifestations of the two patient groups were compared,and a logistic regression model was used to analyze the risk factors for HGIN in these patients.RESULTS The HGIN group was older and had a higher number of sigmoid colon polyps,rectal polyps,pedunculated polyps,polyps≥1.0 cm in size,polyps with surface congestion,polyps with surface depression,and polyps with villous/tubular adenomas,a higher proportion of patients with diabetes and a family history of colorectal cancer,patients who experienced rectal bleeding or occult blood,patients with elevated carcinoembryonic antigen(CEA)and cancer antigen 199(CA199),and lower nutritional levels and higher frailty levels.The polyp location(in the sigmoid colon or rectum),polyp diameter(≥1.0 cm),pathological diagnosis of(villous/tubular adenoma),family history of colorectal cancer,rectal bleeding or occult blood,elevated serum CEA and CA199 levels,lower nutritional levels and higher frailty levels also are independent risk factors for HGIN.CONCLUSION The occurrence of high-grade neoplastic transformation in colorectal polyps is closely associated with their location,size,villous/tubular characteristics,family history,elevated levels of tumor markers,and lower nutritional levels and higher frailty levels.

High-grade serous carcinoma of the fallopian tube in a young woman with chromosomal 4q abnormality:A case report

BACKGROUND Few studies have reported an association between an increased risk of acquiring cancers and survival in patients with 4q deletion syndrome.This study presents a rare association between chromosome 4q abnormalities and fallopian tube highgrade serous carcinoma(HGSC)in a young woman.CASE SUMMARY A 35-year-old woman presented with acute dull abdominal pain and a known chromosomal abnormality involving 4q13.3 duplication and 4q23q24 deletion.Upon arrival at the emergency room,her abdomen appeared ovoid and distended with palpable shifting dullness.Ascites were identified through abdominal ultrasound,and computed tomography revealed an omentum cake and an enlarged bilateral adnexa.Blood tests showed elevated CA-125 levels.Paracentesis was conducted,and immunohistochemistry indicated that the cancer cells favored an ovarian origin,making us suspect ovarian cancer.The patient underwent debulking surgery,which led to a diagnosis of stage IIIC HGSC of the fallopian tube.Subsequently,the patient received adjuvant chemotherapy with carboplatin and paclitaxel,resulting in stable current condition.CONCLUSION This study demonstrates a rare correlation between a chromosome 4q abnormality and HGSC.UBE2D3 may affect crucial cancer-related pathways,including P53,BRCA,cyclin D,and tyrosine kinase receptors,thereby possibly contributing to cancer development.In addition,ADH1 and DDIT4 may be potential influencers of both carcinogenic and therapeutic responses.

Transformation of marginal zone lymphoma into high-grade B-cell lymphoma expressing terminal deoxynucleotidyl transferase:A case report

BACKGROUND High-grade B-cell lymphoma(HGBL)is an unusual malignancy that includes myelocytomatosis viral oncogene(MYC),B-cell lymphoma-2(BCL-2),and/or BCL-6 rearrangements,termed double-hit or triple-hit lymphomas,and HGBL-not otherwise specific(HGBL-NOS),which are morphologically characteristic of HGBL but lack MYC,BCL-2,or BCL-6 rearrangements.HGBL is partially transformed by follicular lymphoma and other indolent lymphoma,with few cases of marginal zone lymphoma(MZL)transformation.HGBL often has a poor prognosis and intensive therapy is currently mainly advocated,but there is no good treatment for these patients who cannot tolerate chemotherapy.CASE SUMMARY We reported a case of MZL transformed into HGBL-NOS with TP53 mutation and terminal deoxynucleotidyl transferase expression.Gene analysis revealed the gene expression profile was identical in the pre-and post-transformed tissues,suggesting that the two diseases are homologous,not secondary tumors.The chemotherapy was ineffective and the side effect was severe,so we tried combination therapy including venetoclax and obinutuzumab.The patient tolerated treatment well,and reached partial response.The patient had recurrence of hepatocellular carcinoma and died of multifunctional organ failure.He survived for 12 months after diagnosis.CONCLUSION Venetoclax combined with obinutuzumab might improve the survival in some HGBL patients,who are unsuitable for chemotherapy.

Prenatal ultrasonography and genetic analysis of fetal cleidocranial dysplasia:A case report

BACKGROUND Cleidocranial dysplasia(CCD)is an infrequent clinical condition with an autosomal dominant inheritance pattern.It is characterized by abnormal clavicles,patent sutures and fontanelles,supernumerary teeth,and short stature.Approximately 60%-70%of patients with CCD have mutations in the RUNX family transcription factor 2 gene.However,prenatal diagnosis of CCD is difficult when the family history is unknown.CASE SUMMARY We report a rare case of fetal CCD with an unknown family history,confirmed by prenatal ultrasonography and genetic testing at a gestational age of 16 weeks.The genetic reports indicated that the fetus carried pathogenic mutations in the RUNX family transcription factor 2 gene(c.674G>A).After careful consideration,the pregnant woman and her family decided to continue the pregnancy.CONCLUSION Definitive prenatal diagnosis of CCD should include family history,ultrasound diagnosis,and genetic analysis,especially if family history is unknown.

Study on Plants Selection and Disposition in High-grade Residences

With rapid development of economy and emergence of more and more high-grade residences,it had highlighted that high-grade residence was the inevitable tendency of economic development and urban construction.Based on the fact that high-grade residences paid more attention to harmony of human and architecture with nature and required higher for landscaping,the paper emphasized that landscape quality of high-grade residences was the key factor deciding quality of the residence.In view of insufficiencies of plant landscaping planning in high-grade residences at home and abroad,by taking high-grade residences in Hangzhou City for example,analysis had been conducted by selecting typical cases.It pointed out that plants disposition in high-grade residences was unreasonable,architectures and landscapes were isolated,and greening ratio was stressed while design was neglected.And then,corresponding solutions had been proposed.In terms of plants selection,it should reasonably utilize native tree species,and properly select new and high-quality plant species.In terms of harmonious unity between plant landscape and architecture,it should lay stress on unity between sensory design and comfort design.In terms of plant design and disposition,it should stick to the theme of "residential environment",so as to rationalize plant design and disposition,and create more comfortable residential environment.

Missed diagnosis of early gastric cancer or high-grade intraepithelial neoplasia

AIM: To investigate the causes of missed diagnosis of early gastric cancer (EGC) or high-grade intraepithelial neoplasia (HGIN) in Chongqing, China. METHODS: The present study summarizes 103 cases of EGC/HGIN detected by esophagogastroduodenos-copy (EGD) and pathological analysis from January 2010 to December 2011. Dimethyl silicone oil was administrated orally 15 min before the EGD procedures. The stomach was cleaned by repeated washing with saline when the gastroscope entered the stomach cavity. Suspected EGC lesions were subject to conventional biopsy sampling and pathological examinations. The correlation between lesion locations, endoscopic morphology of cancerous sites, training level of the examiners, pathological biopsies, and missed diagnosis was analyzed. RESULTS: Twenty-three cases were missed among the 103 cases (22.23%) of EGC/HGIN. The rate of missed EGC in the gastroesophageal junction (8/19, 42.1%) was significantly higher than at other sites (15/84, 17.86%) (χ2 = 5.253, P = 0.022). In contrast, the rate of missed EGC in the lower stomach body (2/14, 14.29%) was lower than at other sites (21/89,23.6%), but there were no significant differences (χ2 = 0.289, P = 0.591). The rate of missed EGC in the gastric antrum (5/33, 15.15%) was lower than at other sites (18/70, 25.71%), but there were no significant differences (χ2 = 1.443, P = 0.230). Endoscopists from less prestigious hospitals were more prone to not diagnosing EGC than those from more prestigious hospitals (χ2 = 4.261, P = 0.039). When the number of biopsies was < 4, the rate of missed diagnosis was higher (20/23, 89.96%) than for when there were > 4 biopsies (3/23, 13.04%) (P < 0.001). In addition, there was no significant difference in the rate of missed diagnosis in patients with 1-3 biopsy specimens (χ2 = 0.141, P = 0.932). CONCLUSION: Endoscopists should have a clear understanding of the anatomical characteristics of the esophagus/stomach, and endoscopic identification of early lesions increases with the number of biopsies.

High-grade myofibroblastic sarcoma in the liver: A case report

Only two cases of myofibroblastic sarcoma in the liver have been reported in the literature. Here, we report the case of a male patient with high-grade myofibroblastic sarcoma mimicking echinococcosis in the liver. The 25-year-old male patient complained of right upper quadrant swelling pain for one week and was initially diagnosed with echinococcosis. He was then scheduled for an exploratory laparotomy. During the operation, a huge mass exceeding 16 cm in diameter was found to occupy nearly the entire right trisegment of the liver, with a clear boundary and a round shape, and the mass was resected by right hepatic trisegmentectomy. Immunohistochemical staining revealed that the tumor tissue was positive for desmin, alpha-smooth muscle actin, CD56, and vimentin and negative for ALK-1, myogenin, calponin, beta-catenin, S100, and glypican-3, with a Ki-67 (MIB-1) index of approximately 20%. Based on the histological manifestations and immunohistochemical staining, a diagnosis of myofibroblastic sarcoma was established. The postoperative recovery was uneventful. There was no evidence of recurrence or metastasis through the last follow-up, 6 mo after surgery, despite a lack of postoperative chemotherapy or radiotherapy. To the best of our knowledge, the present case is the first reported case of high-grade myofibroblastic sarcoma in the liver, and it is also the first reported case in a male patient.

Outcomes of high-grade aneurysmal subarachnoid hemorrhage patients treated with coiling and ventricular intracranial pressure monitoring

BACKGROUND High-grade aneurysmal subarachnoid hemorrhage is a devastating disease with a low favorable outcome.Elevated intracranial pressure is a substantial feature of high-grade aneurysmal subarachnoid hemorrhage that can result to secondary brain injury.Early control of intracranial pressure including decompressive craniectomy and external ventricular drainage had been reported to be associated with improved outcomes.But in recent years,little is known whether external ventricular drainage and intracranial pressure monitoring after coiling could improve outcomes in high-grade aneurysmal subarachnoid hemorrhage.AIM To investigate the outcomes of high-grade aneurysmal subarachnoid hemorrhage patients with coiling and ventricular intracranial pressure monitoring.METHODS A retrospective analysis of a consecutive series of high-grade patients treated between Jan 2016 and Jun 2017 was performed.In our center,followed by continuous intracranial pressure monitoring,the use of ventricular pressure probe for endovascular coiling and invasive intracranial pressure monitoring in the acute phase is considered to be the first choice for the treatment of high-grade patients.We retrospectively analyzed patient characteristics,radiological features,intracranial pressure monitoring parameters,complications,mortality and outcome.RESULTS A total of 36 patients were included,and 32(88.89%)survived.The overall mortality rate was 11.11%.No patient suffered from aneurysm re-rupture.The intracranial pressure in 33 patients(91.67%)was maintained within the normal range by ventricular drainage during the treatment.A favorable outcome was achieved in 18 patients(50%)with 6 mo follow-up.Delayed cerebral ischemia and Glasgow coma scale were considered as significant predictors of outcome(2.066 and-0.296,respectively,P<0.05).CONCLUSION Ventricular intracranial pressure monitoring may effectively maintain the intracranial pressure within the normal range.Despite the small number of cases in the current work,high-grade patients may benefit from a combination therapy of early coiling and subsequent ventricular intracranial pressure monitoring.
