Performance of High Mobility Protein Group 1 and Interleukin-6 as Predictors of Outcomes Resulting from Variceal Bleeding in Patients with Advanced Chronic Liver Disease.

Variceal bleeding is a serious complication in cirrhotic patients and is related to increased expression of inflammatory mediators that accentuate circulatory dysfunction. The study aims to evaluate the performance of high mobility protein group 1 (HMG1) and interleukin-6 (IL-6) as predictors of acute kidney injury (AKI), infection and death in these patients. Fifty patients who were diagnosed with advanced chronic liver disease with variceal bleeding were included. The mean age was 52.8 ± 10.8 years, and 33 (66%) were male. Twenty-one (42%) patients were classified as Child-Pugh C, 21 (42%) Child-Pugh B and 8 (16%) Child-Pugh A. The mean HMG1 serum level was 2872.36 pg/mL ± 2491.94, and the median IL-6 serum level was 47.26 pg/mL (0-1102.4). In AKI, the serum level of HMG1 that performed best on the ROC curve was 3317.9 pg/mL. The IL-6 serum level was not associated with AKI. HMG1 and IL-6 cut-off values that better predicted infection were 3317.9 pg/mL and 72.9 pg/mL, and for mortality, the values were 2668 pg/mL and 84.5 pg/mL, respectively. In multivariate analysis, the variables that were associated with AKI and infection outcomes were model for end-stage liver disease and HMG1. Infections were related to the risk of death. Clinical and laboratory variables related to the outcomes were identified. Serum levels of HMG1 were associated with AKI and infection and had good performance in the ROC curve. IL-6 levels were not maintained in logistic regression outcomes but had good performance in infection and death outcomes. Such data will be useful for comparisons and possible future validations.

ENDOSCOPIC SUBMUCOSAL DISSECTION WITH CIRCUMFERENTIAL INCISION VERSUS TUNNELING METHOD FOR TREATMENT OF SUPERFICIAL ESOPHAGEAL CANCER.

BACKGROUND: Endoscopic submucosal dissection (ESD) of esophageal superficial neoplasm is associated with a high en bloc R0 resection rate and low recurrence. OBJECTIVE: We aim to compare the performance and clinical outcomes of ESD via ESD after circumferential incision (ESD-C) versus submucosal tunneling (ESD-T). METHODS: Single-center retrospective analysis of all consecutive patients who underwent ESD for superficial esophageal cancer, between 2009 and 2018. ESD-T was defined as the technique of making the mucosal incisions followed by submucosal tunneling in the oral to anal direction. ESD-C consisted of completing a circumferential incision followed by ESD. Main study outcomes included en bloc and R0 resection rates. Secondary outcomes included procedural characteristics, curative resection rate, local recurrence and adverse events. RESULTS: A total of 65 procedures (23 ESD-T and 42 ESD-C) were performed for ESCC (40; 61.5%) and BE-neoplasia (25; 38.5%). There were no statistically significant differences between patients who underwent ESD-T versus ESD-C in en bloc (91.3% vs 100%, P=0.12), R0 (65.2% vs 78.6%, P=0.24), curative resection rates (65.2% vs 73.8%, P=0.47) and mean procedure time (118.7 min with vs 102.4 min, P=0.35). Adverse events for ESD-T and ESD-C were as follows: bleeding (0 versus 2.4%; P=0.53), perforation (4.3% vs 0; P=0.61), esophageal stricture (8.7% versus 9.5%; P=0.31). Local recurrence was encountered in 8.7% after ESD-T and 2.4% after ESD-C (P=0.28) at a mean follow-up of 8 and 2.75 years, respectively (P=0.001). CONCLUSION: ESD-T and ESD-C appear to be equally effective with similar safety profiles for the management of superficial esophageal neoplasms.

RESUMO CONTEXTO: A dissecção endoscópica submucosa (DES) no tratamento da neoplasia superficial do esôfago está associada a uma alta taxa de ressecção R0 em bloco e baixa taxa de recorrência. OBJETIVO: O objetivo deste estudo é comparar o desempenho e os resultados clínicos da DES com incisão circunferencial (DES-C) versus com DES com túnel submucoso (DES-TS). MÉTODOS: Estudo retrospectivo de banco de dados coletados prospectivamente de um centro especializado em DES, investigando pacientes consecutivos submetidos à DES por câncer de esôfago superficial, entre 2009 e 2018. DES-TS foi definida como a técnica de realizar primeiro incisões na mucosa seguida de tunelamento submucoso no sentido oral para anal. DES-C consistiu em completar uma incisão circunferencial seguida da dissecção submucosa. As principais variáveis do estudo incluíram taxas de ressecção em bloco e R0. Os resultados secundários incluíram características do procedimento, taxa de ressecção curativa, recorrência local e eventos adversos. RESULTADOS: Um total de 65 procedimentos (23 DES-TS e 42 DES-C) foram realizados para CCE de esôfago (40; 61,5%) e neoplasia associada ao EB (25; 38,5%). Não houve diferenças estatisticamente significativas entre os pacientes submetidos a DES-TS versus DES-C nas taxas de ressecção em bloco (91,3% vs 100%, P=0,12), R0 (65,2% vs 78,6%, P=0,24), taxas de ressecção curativa (65,2% vs 73,8%, P=0,47) e tempo médio do procedimento (118,7 min com vs 102,4 min, P=0,35). Os eventos adversos para DES-TS e DES-C foram os seguintes: sangramento (0 vs 2,4%; P=0,53), perfuração (4,3% vs 0; P=0,61), estenose esofágica (8,7% vs 9,5%; P=0,31). A recorrência local foi encontrada em 8,7% após DES-TS e 2,4% após DES-C (P=0,28) em um seguimento médio de 8 e 2,75 anos, respectivamente (P=0,001). CONCLUSÃO: DES-TS e DES-C demostram ser igualmente eficazes com perfil de segurança semelhante para o tratamento das neoplasias superficiais do esôfago.

Evaluation of the Biomarkers HMGB1 and IL-6 as Predictors of Mortality in Cirrhotic Patients with Acute Kidney Injury.

BACKGROUND: Acute kidney injury (AKI) affects from 20% to 50% of cirrhotic patients, and the one-month mortality rate is 60%. The main cause of AKI is bacterial infection, which worsens circulatory dysfunction through the release of HMGB1 and IL-6. OBJECTIVES: To evaluate HMGB1 and IL-6 as biomarkers of morbidity/mortality. METHODS: Prospective, observational study of 25 hospitalised cirrhotic patients with AKI. Clinical and laboratory data were collected at the time of diagnosis of AKI, including serum HMGB1 and IL-6. RESULTS: The mean age was 55 years; 70% were male. Infections accounted for 13 cases. The 30-day and three-month mortality rates were 17.4% and 30.4%, respectively. HMGB1 levels were lower in survivors than in nonsurvivors at 30 days (1174.2 pg/mL versus 3338.5 pg/mL, p = 0.035), but not at three months (1540 pg/mL versus 2352 pg/mL, p = 0.243). Serum IL-6 levels were 43.3 pg/mL versus 153.3 pg/mL (p = 0.061) at 30 days and 35.8 pg/mL versus 87.9 pg/mL (p = 0.071) at three months, respectively. The area under the ROC curve for HMGB1 was 0.842 and 0.657, and that for IL-6 was 0.803 and 0.743 for discriminating nonsurvivors at 30 days and three months, respectively. In multivariate analysis, no biomarker was independently associated with mortality. CONCLUSION: HMGB1 levels were associated with decreased survival in cirrhotics. Larger studies are needed to confirm our results.

Does a history of head and neck cancer affect outcome of endoscopic submucosal dissection for superficial esophageal squamous cell carcinoma?

Background and study aims Esophageal squamous cell carcinoma (ESCC) is the most common secondary tumor in patients with head and neck squamous cell cancer (HNSCC). Currently, endoscopic submucosal dissection (ESD) is the preferred approach to manage superficial ESCC, however, it remains to be elucidated whether patients with HNSCC and early ESCC managed by ESD have different outcomes. Patients and methods We retrospectively analyzed esophageal ESD for early ESCC from September 2009 to September 2017 and the following variables: demographics, tumor and specimen size, Paris classification, location, en bloc and R0 resection rates, overall survival (OS) and adverse events (AEs). To reduce selection bias, propensity score matching was applied to compare the results. Results Eighty-nine ESDs were performed in 81 consecutive patients (47 with HNSCC and 34 without HNSCC). Patients with HNSCC who developed superficial ESCC were found to be younger and to refer a more frequent history of alcohol ingestion and smoking. There was no difference in lesion size, number of lesions, procedure time, en bloc resection rate, R0 resection rate, local recurrence and adverse event rate between the two groups. The histological depth of invasion for patients with HNSCC was significantly shallower before ( P  = 0.016) and after ( P  = 0.047) matching. The overall survival rate was similar in both groups. Conclusions Patients with HNSCC have earlier detection of ESCC, probably due to endoscopic screening. Previous history of chemoradiation and surgery for HNSCC does not affect procedure time, AEs and OS.

Tumor desmóide de parede torácica recidivado / Recurrent desmoid tumor of the chest wall

Tumor desmóide (TD) ou fibromatose agressiva é um tipo raro de neoplasia de partes moles que não causa metástases, mas apresenta alto poder de infiltração por estruturas músculo-aponeuróticas adjacentes. O tratamento é agressivo, consistindo principalmente em ressecção cirúrgica com margens livres, também contando com a radioterapia, utilização de antiinflamatório não esteroidal (AINE´s), agentes hormonais e quimioterapia. A incidência de recidiva local após tratamento primário é alta. O presente trabalho relata o caso de um paciente que apresentou tumor desmóide recidivado em dorso, sendo submetido à cirurgia, que consistiu em toracotomia, apofisectomia, osteotomia, biópsia de parênquima pulmonar de lobo inferior esquerdo, drenagem fechada de pleura, reconstrução imediata com rotação de retalhos musculares e colocação de tela. Após procedimento cirúrgico o paciente foi submetido a 23 ciclos de radioterapia associados a doses diárias de Tamoxifeno (40mg/dia). Trinta meses após cirurgia, o paciente encontra-se livre de doença, assintomático e em acompanhamento.

Desmoid tumor (DT) or aggressive fibromatosis is a rare type of soft tissue neoplastic disorder that does not metastasize, but is highly infiltrative on the adjacent muscle and aponeurosis. Treatment must be aggressive, and consists mainly of surgical resection with free margins, although radiotherapy, non-steroidal anti-inflammatory drugs, hormones and chemotherapy may be used. Local relapse rate after primary treatment is high. We report a patient who had a relapse of desmoid tumor on the dorsum, and who underwent thoracotomy, apophysectomy, osteotomy, biopsy of the left lower lobe of the lung, closed pleural space drainage, immediate reconstruction with rotation of muscle flaps and mesh repair. After surgery, the patient received 23 cycles of radiotherapy associated with tamoxifen (40 mg/day). Thirty months after surgery, the patient shows no signs of the disease, no symptons at all and is currently being observed.
