A case of large cell neuroendocrine carcinoma exhibiting rhabdoid features in the esophagogastric junction.	"We report a case of large cell neuroendocrine carcinoma with rhabdoid features in the esophagogastric junction. An 81-year-old man presented to Saku Central Hospital Advanced Care Center with a tumor in the esophagogastric junction. During upper gastrointestinal endoscopy, an ulcerative tumor, measuring 4 × 3 cm in diameter, was observed. Computed tomography revealed lymph node metastasis, but no metastasis to other organs was observed. A thoracoscopic subtotal esophagectomy was performed. Histopathologically, anaplastic large cells exhibited a solid growth pattern with focal and geographic necrosis. Approximately half of the tumor cells exhibited large nuclei with conspicuous nucleoli; an eosinophilic ""rhabdoid"" cytoplasmic inclusion; and a nucleus displaced eccentrically by the cytoplasmic inclusion body. Immunohistochemically, tumor cells, including rhabdoid cells, were focally positive for pan-cytokeratin and diffusely positive for vimentin and synaptophysin. Additionally, electron microscopy identified dense-core granules in the tumor cells. Therefore, a diagnosis of large cell neuroendocrine carcinoma with rhabdoid features was made. A few cases of esophageal neuroendocrine tumors with rhabdoid features have been reported in the lung and pancreas; however, this is the first report of large cell neuroendocrine carcinoma with rhabdoid features in the esophagogastric junction."	esophagus
Simultaneous Integrated Boost Volumetric Modulated Arc Therapy for Middle or Lower Esophageal Cancer Using Elective Nodal Irradiation: Comparison with 3D Conformal Radiotherapy.	We investigated the feasibility of simultaneous integrated boost (SIB) volumetric modulated arc therapy (VMAT) using elective nodal irradiation (ENI) for middle or lower esophageal cancer and compared it with three-dimensional conformal radiotherapy (3D-CRT). The study included 15 patients. The prescribed doses included a standard dose (50.4 Gy) and a high dose (60 Gy) for the planning target volume (PTV) of the involved lesions. The objective of the whole lung volume receiving ≥ 20 Gy (V20Gy) was < 30%, and the mean lung dose (MLD) was < 20 Gy. The volumes of the lung receiving 5 Gy (V5Gy) and the heart receiving 30-50 Gy (V30-50Gy) were kept as low as reasonably achievable. As a result, SIB-VMAT showed superior dose conformity for the PTV (p<0.001). Although the lung V5Gy was significantly increased (p<0.001), the V20Gy and MLD showed no significant increase. The heart V30-50Gy showed a > 20% reduction in the mean against 3D-CRTs. Our results demonstrate the feasibility of SIB-VMAT for the treatment of middle or lower esophageal cancer with ENI. Although attention should be paid to the low-dose area of the lungs, SIB-VMAT would be a promising treatment option with improved outcomes for esophageal cancer.	esophagus
Pertuzumab in combination with trastuzumab and chemotherapy for Chinese patients with HER2-positive metastatic gastric or gastroesophageal junction cancer: a subpopulation analysis of the JACOB trial.	BACKGROUND: The JACOB trial (NCT01774786) was a double-blinded, placebo-controlled, randomized, multicenter, international, phase III trial evaluating the efficacy and safety of adding pertuzumab to trastuzumab and chemotherapy in first-line treatment of human epidermal growth factor receptor 2 (HER2)-positive metastatic gastric cancer/gastroesophageal junction cancer (GEJC). The aim of this analysis was to investigate efficacy and safety outcomes in the Chinese subpopulation from the JACOB trial. METHODS: This post hoc subpopulation analysis included all patients recruited in mainland China (n = 163; 20.9%) between June 2013 and January 2016. The patients were randomly assigned in a 1:1 ratio to receive pertuzumab plus trastuzumab and chemotherapy (pertuzumab group; n = 82) or placebo plus trastuzumab and chemotherapy (control group; n = 81). Intravenous pertuzumab (840 mg) and trastuzumab (8 mg/kg loading and 6 mg/kg maintenance doses) were given every 3 weeks until disease progression or unacceptable toxicity. Chemotherapy was given as per standard regimens/doses of capecitabine or 5-fluorouracil plus cisplatin. The primary endpoint was overall survival (OS); secondary efficacy endpoints included progression-free survival (PFS), and overall objective response rate (ORR). RESULTS: The median OS was 18.7 months in the pertuzumab group and 16.1 months in the control group (hazard ratio [HR] 0.75; 95% confidence interval [CI] 0.49 to 1.14). The median PFS was 10.5 and 8.6 months in the pertuzumab and control groups, respectively (HR 0.85; 95% CI 0.60 to 1.21), and the median ORRs were 68.9% and 55.7%, respectively. The treatment effect in this Chinese subpopulation showed consistency with that in the global ITT population with numerically lower HR for OS and PFS compared with the control group. The safety profiles of the pertuzumab and control groups in this Chinese subpopulation analysis were generally comparable. The most common grade 3-5 adverse events were neutropenia, anemia, and leukopenia. However, due to the nature of being a post hoc subgroup analysis, the results presented here are descriptive only and need to be interpreted with caution. CONCLUSIONS: OS and PFS were numerically improved by adding pertuzumab to trastuzumab and chemotherapy as first-line treatment in Chinese HER2-positive gastric cancer/GEJC patients, and this regimen demonstrated an acceptable safety profile.

Ramucirumab and paclitaxel in patients with gastric cancer and prior trastuzumab: subgroup analysis from RAINBOW study.	Aim: This subgroup analysis of the RAINBOW study evaluated the efficacy and safety of ramucirumab in patients with gastric cancer/gastroesophageal junction adenocarcinoma who received prior trastuzumab therapy. Patients & methods: Of adult patients enrolled in the RAINBOW study, 39 had received prior trastuzumab therapy. Of these, 20 patients were treated with ramucirumab plus paclitaxel and 19 patients with placebo plus paclitaxel within the RAINBOW trial. Results: Overall survival was longer with ramucirumab plus paclitaxel (11.4 months; 95% CI: 7.0-17.9) versus placebo plus paclitaxel (7.0 months; 95% CI: 3.4-14.6), hazard ratio: 0.68 (0.33-1.41); p = 0.30. Longer progression-free survival, higher objective response were observed in ramucirumab combination group. Conclusion: Ramucirumab plus paclitaxel demonstrated efficacy benefits with manageable safety profile in a subgroup of patients pretreated with trastuzumab. Clinical trial registration number: NCT01170663.	esophagus
Clinical outcomes of per-oral endoscopic tumor resection for submucosal tumors in the esophagus and gastric cardia.	OBJECTIVES: The clinical success of per-oral endoscopic myotomy (POEM) has led to the development of a new field of 'submucosal endoscopy'. This study aimed to evaluate the safety, efficacy, and limitations of per-oral endoscopic tumor resection (POET) in the management of submucosal tumors (SMTs) in the esophagus and the gastric cardia. METHODS: POET was performed in 47 patients from January 2011 to December 2017. The indication for POET was SMTs ≤ 30 mm in minor axis diameter. Patient and tumor characteristics (age, gender, tumor location, size, and histology), operative and clinical results of POET (procedure time and completion rate, en bloc resection rate, length of hospitalization, adverse events and tumor recurrence) were analyzed retrospectively. RESULTS: POET was successfully completed in 43 patients (91.5%) without any major adverse events (Clavien-Dindo IIIb-IV). Four patients required conversion to an open surgical procedure due to suboptimal visualization during POET. Four patients underwent piecemeal resection of their SMTs including GISTs. Median follow-up was 44 months (10-96 months), during that time, there were no incidences of tumor recurrence. Tumors that had a minor axis diameter > 30 mm or a tumor mass index (TMI) [major axis diameter (mm) × minor axis diameter (mm)] >1000 had a high likelihood of being converted to surgical resection. CONCLUSIONS: POET is a safe and effective treatment for SMTs. However, in patients where the minor axis diameter is > 30 mm or the TMI > 1000, surgical excision should be considered. Furthermore, application of POET for SMTs with malignant potential should be carefully considered to ensure optimal oncologic outcomes.	esophagus
Comparison of enteral nutrition with total parenteral nutrition for patients with locally advanced unresectable esophageal cancer harboring dysphagia in definitive chemoradiotherapy.	BACKGROUND: The nutritional status of patients with esophageal squamous cell carcinoma (ESCC) harboring dysphagia is often poor. The efficacy and safety of enteral nutrition (EN) versus total parenteral nutrition (TPN) have not been addressed in patients with ESCC requiring nutritional support during definitive chemoradiotherapy (dCRT). METHODS: We performed a retrospective analysis of 51 locally advanced unresectable ESCC patients with dysphagia receiving EN (n = 28) or TPN (n = 23) during dCRT between 2009 and 2016. RESULTS: Patient characteristics in EN vs. TPN were as follows: median age (range), 67 (34 to 82) vs. 66 (57 to 83); ECOG performance status 0/1/2, 11/15/2 vs. 7/14/2; dysphagia score 2/3/4, 11/15/2 vs. 14/8/1; and primary tumor location Ce/Ut/Mt/Lt/Ae, 4/6/14/3/1 vs. 2/2/16/1/2. Median changes in serum albumin level one month after dCRT were +8.8% (-36 to 40) in EN and -12% (-64 to 29) in TPN (P = 0.00377). Weight, body mass index, and skeletal muscle area were not significantly different between the groups. Median durations of hospitalization were 50 days (18 to 72) in EN and 63 days (36 to 164) in TPN (P = 0.00302). Adverse events during dCRT in EN vs. TPN were as follows: catheter-related infection, 0 vs. 6 (27%); aspiration pneumonia, 3 (11%) vs. 2 (9%); mediastinitis, 3 (11%) vs. 1 (5%); grade ≥3 neutropenia, 6 (21%) vs. 14 (64%) (P = 0.00287); and febrile neutropenia, 0 vs. 6 (27%) (P = 0.00561). CONCLUSIONS: EN may be advantageous for improving serum albumin level, and reducing hematological toxicity and duration of hospitalization compared with TPN during dCRT in ESCC patients.	esophagus
[Study on safety of adjuvant radiotherapy concurrent with weekly chemotherapy for stage ⅡB-ⅣA esophageal carcinoma after radical resection].	Objective: To evaluate the tolerability and short-term efficacy of chemo-radiotherapy in 125 patients with stage ⅡB-ⅣA esophageal carcinoma after radical resection. Methods: We retrospectively evaluated the rate of completion, toxicity and survival of patients undergoing adjuvant concurrent chemo-radiotherapy after radical resection of esophageal carcinoma from January 2004 to December 2014 in our institution. The survival rate was determined by the Kaplan-Meier method and analyzed using the log-rank test. Multivariate prognostic analysis was performed using the Cox proportional hazard model. Results: 122 patients received more than 50 Gy dose (97.6%). A total of 52 patients received more than 5 weeks chemo-radiotherapy (41.6%), while 73 patients underwent only 1-4 weeks (58.4%). The median following up was 48.4 months. 8 patients lost follow up (6.4%). The 1-year and 3-year overall survival rate were 91.6% and 57.0%, respectively, with a median survival time of 64.4 months. The 1-year and 3-year disease free survival rate were 73.2% and 54.3%, respectively, with a median disease free survival time of 59.1 months. The most common acute complications associated with chemo-radiotherapy were myelosuppression, radiation esophagitis and radiation dermatitis, the majority of which were Grade 1-2. Of the 125 patients, there were 59 cases of recurrence, including 23 cases with local regional recurrence, 26 cases with hematogenous metastasis, and 8 cases with mixed recurrence. Univariate analysis showed that the numbers of concurrent chemotherapy was associated with the overall survival (P=0.006). But receiving more than 5 weeks was not the prognostic factor compared to 1 to 4 weeks chemotherapy (P=0.231). Multivariate analysis showed that only the numbers of concurrent chemotherapy was an independent prognostic factor (P=0.010). Conclusions: Postoperative radiotherapy concurrent with weekly chemotherapy could improve the overall survival and decrease the recurrence for stage ⅡB-ⅣA esophageal carcinoma after radical resection. However, the completion rate of chemotherapy was low, so it was necessary to explore reasonable regimens to improve the completion rate and carry out prospective randomized controlled trial.	esophagus
Comparison Between Submucosal Tunneling Endoscopic Resection (STER) and Other Resection Modules for Esophageal Muscularis Propria Tumors: A Retrospective Study.	BACKGROUND Surgery has been considered to be the primary approach for resection of esophageal muscularis propria tumors. With the development of endoscopic technology, new techniques such as endoscopic submucosal dissection (ESD) and submucosal tunneling endoscopic resection (STER) have emerged for resecting these lesions. Previous studies have demonstrated that STER might be an intriguing alternative. This study aimed to evaluate the clinical value of STER by comparing it to other resecting modules. MATERIAL AND METHODS Clinical outcome and data were retrospectively collected from patients with esophageal muscularis propria tumors who underwent resection either endoscopically or thoracoscopically. The clinical data were statistically analyzed. RESULTS A total of 137 patients were enrolled. They were divided into 3 groups: a STER group (27 patients), an ESD group (42 patients), and a thoracoscopic enucleation (TE) group (68 patients). There were no significant differences among the 3 groups in gender, age, pathological type of tumors, or major adverse events (P>0.05). However, the STER group had the shortest duration of hospitalization and the lowest cost (P<0.05). Furthermore, the STER group was superior in operation time and the location of tumors to the TE group. Moreover, STER outperformed ESD in the resection of large tumors (P<0.05). Although STER had the lowest en bloc resection rate, no recurrence or metastasis was noted during a mean follow-up of 22.14 months (range 3 to 60 months). CONCLUSIONS STER is a feasible, safe, and effective approach for the resection of esophageal muscularis propria tumors ≤40 mm. We recommend STER as a potent alternative for these tumors.	esophagus
Esophageal tuberculosis in an HIV-positive patient mimicking a spindle cell tumor.	Tuberculosis (TB) of the esophagus is an extremely rare condition, even in immunocompromised patients. We report the case of a 24-year-old man with a past history of HIV and pulmonary tuberculosis who presented with dysphagia and a 2cm submucosal mass in the proximal esophagus. The biopsy was diagnosed as a spindle cell neoplasm in another center. Sections displayed a submucosal lesion formed by spindle and epithelioid cells, surrounded by chronic inflammation. The spindle cells were positive for S100 and CD68, but negative for cytokeratin, desmin, smooth muscle actin, ALK, CD34 and CD117. Ziehl-Neelsen stain was performed and showed many intracellular acid-fast bacilli, confirming the diagnosis of esophageal TB. This case is a reminder that esophageal TB may become manifest as a submucosal lesion and the histiocytic-granulomatous reaction may mimic a spindle cell tumor.	esophagus
Experience in Simultaneous Endoscopic Submucosal Dissection Treating Synchronous Multiple Primary Early Esophageal Cancers.	Objective: Synchronous multiple primary early esophageal cancers (SMPEEC) are rare and aggressive. Early detection of esophageal cancer can improve survival rate. Endoscopic submucosal dissection (ESD) is a minimally invasive endoscopic treatment of early esophageal cancers. However, ESD for SMPEEC is little known. We aimed to clarify the clinical outcomes of simultaneous ESD treating SMPEEC. Methods: We retrospectively reviewed the medical data of 34 patients, who underwent ESD for SMPEEC at Endoscopy Center of Zhongshan Hospital, Fudan University, between May 2013 and December 2014. The data of lesion size, histopathology, en bloc resection, curative resection, complication, and tumor local recurrence were analyzed. Results: Among 34 patients, 67 lesions were removed simultaneously in 33 cases; 2 lesions were removed in 2 operations for 1 case. For the simultaneous resection, the en bloc rate was 97.01% (65/67) and the curative resection rate was 92.54% (62/67). Postoperative stricture occurred in two cases and delayed bleeding occurred in one case. There was one local recurrence, no metastasis or procedure-related death. Conclusions: Simultaneous ESD as a treatment for SMPEEC is technically feasible, benefited from reducing hospitalization time and medical expenses. For the cases with risk factors of complications, simultaneous ESD needs to be avoided.	esophagus
CCL18-induced HOTAIR upregulation promotes malignant progression in esophageal squamous cell carcinoma through the miR-130a-5p-ZEB1 axis.	Accumulating evidence indicates that CCL18 and the long non-coding RNA, HOTAIR, have critical roles in cancer progression and metastasis, but the correlation between CCL18 and HOTAIR in esophageal squamous cell carcinoma (ESCC) and their downstream molecular mechanisms remain unclear. Overexpression of CCL18 in ESCC tissues was associated with a worse survival in patients with ESCC. CCL18 enhanced the invasiveness of ESCC cells in a dose-dependent manner, whereas CCL18 knockdown inhibited their invasiveness. In particular, CCL18 expression was positively associated with HOTAIR expression in ESCC tissues. Furthermore, CCL18 upregulated the expression of HOTAIR, and knockdown of HOTAIR alleviated the CCL18-induced invasiveness of ESCC cells. HOTAIR may act as a competing endogenous RNA and could effectively becoming a sponge for miR-130a-5p, thereby modulating the derepression of ZEB1 and promoting epithelial-mesenchymal transition in ESCC. Our study suggests that CCL18 contributes to the malignant progression of esophageal cancer by upregulating HOTAIR expression. HOTAIR overexpression may promote tumor invasiveness and progression in ESCC, given that HOTAIR functions as a miR-130a-5p sponge, positively regulating ZEB1. This provides new therapeutic targets for early diagnosis and treatment of ESCC.	esophagus
Radiofrequency Ablation in Patients with Barrett's Esophagus- related Neoplasia - Long-Term Outcomes in the Czech National Database.	BACKGROUND AND AIMS: Radiofrequency ablation (RFA) with/without endoscopic resection (ER) is the standard endoscopic treatment modality for Barrett's esophagus (BE) related neoplasia (BORN). The main aim of this study was to assess the long-term outcomes of RFA in patients with BORN. METHODS: We retrospectively analyzed the prospectively collected data from the Czech national database. Main outcomes were: complete remission of neoplasia (CR-N), complete remission of intestinal metaplasia (CR-IM), recurrence of both neoplasia and IM, and safety. RESULTS: From a total of 170 patients with BORN treated with RFA, 136 patients were analyzed. They were followed up for a median of 27.5 months. Fifty-six patients (41%) had low-grade intraepithelial neoplasia (LGIN), 46 (34%) had high-grade intraepithelial neoplasia (HGIN) and 34 (25%) had early adenocarcinoma (EAC). RFA was combined with previous ER in 65 patients (48%). CR-IM and CR-N were achieved in 77.9% (95% CI 70.0-84.6%) and 98.5% (95% CI 94.8-99.8%). Among 30 patients without CR-IM, 22 (73%) did not have macroscopic signs of BE. Recurrent neoplasia was detected in 4.5% of patients (6/134) and 15% (16/106) experienced a recurrence of IM at the level of the neo-Z-line. Diagnosis of cancer was an independent risk factor for recurrent IM after RFA (OR 7.0, 95% CI 1.6-30.9, p<0.0005). CONCLUSION: RFA is highly effective in achieving remission in patients with BORN. A significant proportion of patients did not achieve CR-IM or had a recurrence of IM despite macroscopically absent BE. Recurrence of neoplasia was infrequent but not negligible, thus, patients after successful RFA still require endoscopic surveillance.	esophagus
LINC00184 silencing inhibits glycolysis and restores mitochondrial oxidative phosphorylation in esophageal cancer through demethylation of PTEN.	BACKGROUND: Total lesion glycolysis has been reported to be a satisfactory predictor of survival in patients with locally advanced esophageal cancer (EC). The aim of the present study is to investigate the function of long intergenic non-protein coding RNA 184 (LINC00184) on the EC cell glycolysis and mitochondrial oxidative phosphorylation (OXPHOS). METHODS: The expression of LINC00184 was determined to be highly expressed and PTEN was poorly expressed in EC tissues and cells by RT-qPCR. In order to evaluate the effects of LINC00184 on cellular process in vitro and in vivo, gain- and loss-of-function approaches were performed to alter the expression of LINC00184 and PTEN in EC cells. RESULTS: Silencing of LINC00184 was observed to inhibit the proliferation, migration, invasion, colony formation, and glycolysis of EC cells and tumour growth, while the mitochondrial OXPHOS was restored. By recruiting DNMT1, LINC00184 enhanced the promoter methylation of PTEN. Inhibition of PTEN promoter methylation suppressed EC glycolysis, whereas, improved mitochondrial OXPHOS. Mechanically, LINC00184 modulated glycolysis and mitochondrial OXPHOS in EC cells through induction of the Akt phosphorylation. After blockage of Akt signaling pathway by an Akt inhibitor, LY294002, the regulatory effects of LINC00184 on the glycolysis and mitochondrial OXPHOS of EC cells were reversed. CONCLUSION: Taken together, the LINC00184/PTEN/Akt axis mediates glycolysis and mitochondrial OXPHOS in EC cells. This study highlighted a potential intervention target for treating EC.	esophagus
Aberrant expression of Sec61α in esophageal cancers.	INTRODUCTION: The heterotrimeric Sec61α translocon complex is topological located in the membrane of the endoplasmic reticulum (ER) and allows protein transport and calcium across the membrane. Recently, aberrant expression of Sec proteins was linked to carcinogenesis and prognosis of patients. MATERIALS AND METHODS: Here, we analysed the role of Sec61α in esophageal cancer, and we analysed Sec61α staining on a tissue microarray containing more than 600 esophageal cancer specimens by immunohistochemistry. RESULTS: Sec61α staining was always strong in benign esophagus, but was only found in 5% of interpretable esophageal adenocarcinomas (EACs) and 14.5% of squamous cell carcinomas (ESCCs). Reduced Sec61α staining was not strongly linked to tumor phenotype in both subgroups of esophageal cancers and was unrelated to clinical outcome of patients (EACs: p = 0.8051 and ESCCs: p = 0.2751). CONCLUSIONS: Thus, Sec61α measurement has not an additional prognostic benefit for the patients.	esophagus
