RESUMO
The factors related to oropharyngeal dysphagia after remote esophagectomy (greater than five months) remain unclear. This study aimed to assess patient perception of dysphagia, maximum anterior isometric pressure (MAIP), maximum posterior isometric pressure (MPIP), lingual swallowing pressure (LSP) and radiographic physiological components of the oral and pharyngeal phases of swallowing in patients who are post remote sub-total esophagectomy (SE). Patient perception of dysphagia was assessed using the Eating Assessment Tool (EAT-10). MAIP, MPIP, and LSP were measured using the Iowa Oral Performance Instrument. Videofluoroscopy was used to assess the physiologic components of swallowing with the Modified Barium Swallow Impairment Profile (MBSImP) and the Penetration-Aspiration Scale (PAS). Ten patients were included in the study (53.2% male; mean age 54.5 ± 18.0). The mean postoperative time was 30 months (range, 5.0-72 months). Seven patients had elevated EAT-10 scores (> 3). All patients demonstrated impaired oropharyngeal swallowing on at least three MBSImP components (range 3-12) and two patients aspirated (PAS 8). There was a significant difference in MAIP values when comparing patients with normal versus impaired laryngeal elevation and epiglottic movement (p < 0.001). MPIP values were significantly different in patients with normal versus impaired epiglottic movement as well as normal versus elevated PAS scores (p < 0.001). Decreased lingual pressure and physiological changes in swallowing coexist after SE. Our results indicate that the decrease in tongue strength may be one of the factors related to unsafe swallow. The assessment of lingual pressure provides diagnostic value and should be incorporated as part of a comprehensive assessment in this population.
RESUMO
BACKGROUND: Curative treatment for gastric cancer involves tumor resection, followed by transit reconstruction, with Roux-en-Y being the main technique employed. To permit food transit to the duodenum, which is absent in Roux-en-Y, double transit reconstruction has been used, whose theoretical advantages seem to surpass the previous technique. AIMS: To compare the clinical evolution of gastric cancer patients who underwent total gastrectomy with Roux-en-Y and double tract reconstruction. METHODS: A systematic review was carried out on Web of Science, Scopus, EmbasE, SciELO, Virtual Health Library, PubMed, Cochrane, and Google Scholar databases. Data were collected until June 11, 2022. Observational studies or clinical trials evaluating patients submitted to double tract (DT) and Roux-en-Y (RY) reconstructions were included. There was no temporal or language restriction. Review articles, case reports, case series, and incomplete texts were excluded. The risk of bias was calculated using the Cochrane tool designed for randomized clinical trials. RESULTS: Four studies of good methodological quality were included, encompassing 209 participants. In the RY group, there was a greater reduction in food intake. In the DT group, the decrease in body mass index was less pronounced compared to preoperative values. CONCLUSIONS: The double tract reconstruction had better outcomes concerning body mass index and the time until starting a light diet; however, it did not present any advantages in relation to nutritional deficits, quality of life, and post-surgical complications.

The field of medicine has always been at the forefront of technological innovation, constantly seeking new strategies to diagnose, treat, and prevent diseases. Guidelines for clinical practice to orientate medical teams regarding diagnosis, treatment, and prevention measures have increased over the years. The purpose is to gather the most medical knowledge to construct an orientation for practice. Evidence-based guidelines follow several main characteristics of a systematic review, including systematic and unbiased search, selection, and extraction of the source of evidence. In recent years, the rapid advancement of artificial intelligence has provided clinicians and patients with access to personalized, data-driven insights, support and new opportunities for healthcare professionals to improve patient outcomes, increase efficiency, and reduce costs. One of the most exciting developments in Artificial Intelligence has been the emergence of chatbots. A chatbot is a computer program used to simulate conversations with human users. Recently, OpenAI, a research organization focused on machine learning, developed ChatGPT, a large language model that generates human-like text. ChatGPT uses a type of AI known as a deep learning model. ChatGPT can quickly search and select pieces of evidence through numerous databases to provide answers to complex questions, reducing the time and effort required to research a particular topic manually. Consequently, language models can accelerate the creation of clinical practice guidelines. While there is no doubt that ChatGPT has the potential to revolutionize the way healthcare is delivered, it is essential to note that it should not be used as a substitute for human healthcare professionals. Instead, ChatGPT should be considered a tool that can be used to augment and support the work of healthcare professionals, helping them to provide better care to their patients.

BACKGROUND: Caustic ingestion is still a health problem of utmost importance in the West. In developing countries, this incident remains at increase and it is associated with unfavorable factors like social, economic, and educational handicaps, besides a lack of prevention. Esophagocele is a rare consequence of caustic ingestion. AIM: We aimed to describe a patient with multiple caustic ingestions who presented an esophagocele resected by videothoracoscopy. METHODS: A woman ingested caustic soda when she was only 17 years old in a suicidal attempt during a depressive crisis. Initially, she was submitted to a retrosternal esophagocoloplasty with the maintenance of her damaged esophagus. After 1 year of this first surgery, she ingested caustic soda again in a new suicidal attempt. Her transposed large bowel in the first surgery became narrow, being replaced in a second surgery by a retrosternal esophagogastroplasty. Still, at the second surgery, her damaged esophagus remained in its original position in the posterior mediastinum. However, after 5 years, she developed an esophagocele. RESULTS: The esophagocele was resected through videothoracoscopy in a prone position, employing four trocars. The postoperative was uneventful. CONCLUSION: Esophageal exclusion must always be recorded because esophagocele presents unspecific symptoms. The videothoracoscopy in a prone position is an excellent technical option to resect esophagoceles.

BACKGROUND: Gastric neuroendocrine tumors are a heterogeneous group of neoplasms that produce bioactive substances. Their treatment varies according to staging and classification, using endoscopic techniques, open surgery, chemotherapy, radiotherapy, and drugs analogous to somatostatin. AIMS: To identify and review cases of gastric neuroendocrine neoplasia submitted to surgical treatment. METHODS: Review of surgically treated patients from 1983 to 2018. RESULTS: Fifteen patients were included, predominantly female (73.33%), with a mean age of 55.93 years. The most common symptom was epigastric pain (93.3%), and the mean time of symptom onset was 10.07 months. The preoperative upper digestive endoscopy (UDE) indicated a predominance of cases with 0 to 1 lesion (60%), sizing ≥1.5 cm (40%), located in the gastric antrum (53.33%), with ulceration (60%), and Borrmann III (33.33%) classification. The assessment of the surgical specimen indicated a predominance of invasive neuroendocrine tumors (60%), with angiolymphatic invasion in most cases (80%). Immunohistochemistry for chromogranin A was positive in 60% of cases and for synaptophysin in 66.7%, with a predominant Ki-67 index between 0 and 2%. Metastasis was observed in 20% of patients. The surgical procedure most performed was subtotal gastrectomy with Roux-en-Y reconstruction (53.3%). Tumor recurrence occurred in 20% of cases and a new treatment was required in 26.67%. CONCLUSIONS: Gastric neuroendocrine tumors have a low incidence in the general population, and surgical treatment is indicated for advanced lesions. The study of its management gains importance in view of the specificities of each case and the need for adequate conduct to prevent recurrences and complications.

BACKGROUND: Achalasia is an esophageal motility disorder, and myotomy is one of the most used treatment techniques. However, symptom persistence or recurrence occurs in 9 to 20% of cases. AIMS: This study aims to provide a practical approach for managing the recurrence or persistence of achalasia symptoms after myotomy. METHODS: A critical review was performed to gather evidence for a rational approach for managing the recurrence or persistence of achalasia symptoms after myotomy. RESULTS: To properly manage an achalasia patient with significant symptoms after myotomy, such as dysphagia, regurgitation, thoracic pain, and weight loss, it is necessary to classify symptoms, stratify severity, perform appropriate tests, and define a treatment strategy. A systematic differential diagnosis workup is essential to cover the main etiologies of symptoms recurrence or persistence after myotomy. Upper digestive endoscopy and dynamic digital radiography are the main tests that can be applied for investigation. The treatment options include endoscopic dilation, peroral endoscopic myotomy, redo surgery, and esophagectomy, and the decision should be based on the patient's individual characteristics. CONCLUSIONS: A good clinical evaluation and the use of proper tests jointly with a rational assessment, are essential for the management of symptoms recurrence or persistence after achalasia myotomy.

BACKGROUND/OBJECTIVES: The association between systemic inflammation and myosteatosis upon diagnosis of gastric cancer (GC) and whether these factors could predict survival outcomes is not clear. Our aim was to explore the association between systemic inflammation and myosteatosis upon diagnosis of GC, specially whether the co-occurrence of these factors could predict survival outcomes. SUBJECTS/METHODS: Computed tomography (CT) was performed at the level of the third lumbar vertebra for body composition analysis in 280 patients with GC. Myoesteatosis was defined as the lowest tertile of the muscle radiodensity distribution or based on clinical significance using optimal stratification analysis. Inflammatory indexes were measured, including the neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte and lymphocyte-to-monocyte ratios. RESULTS: Patients with low skeletal muscle (SM) radiodensity were more likely to be older than 65 years, have a higher body mass index and have diabetes. They also had higher intermuscular visceral and subcutaneous adipose tissue areas and indexes. The highest tertile of SM radiodensity was associated with better disease-free survival (DFS) (HR = 0.51, 95% CI [0.31, 0.84], ptrend = 0.020) and overall survival (OS) (HR = 0.49, 95% CI [0.29, 0.82], ptrend = 0.022). Patients with NLR > 2.3 and myosteatosis had the worst DFS and OS (HR = 2.77, 95% CI [1.54, 5.00], p = 0.001; HR = 3.31, 95% CI [1.79, 6.15], p < 0.001, respectively). CONCLUSION: Co-occurrence of myosteatosis and inflammation increased disease progression and death risk by almost three times. These regularly obtained biomarkers might improve prognostic risk prediction in resectable GC.

Cancer is a leading cause of death, and the fibrinolytic system shows cooperative effects that facilitate the growth of tumors and the appearance of metastases. This prospective study aimed to evaluate the fibrinolytic potential in cancer patients and its association with mortality outcomes using the fluorometric method of simultaneous thrombin and plasmin generation. The study included 323 cancer patients and 148 healthy individuals. During the 12-month follow-up, 68 patients died. Compared to the control group, cancer patients showed alterations in thrombin production consistent with a hypercoagulability profile, and an increase in plasmin generation. Mortality risk was associated with two parameters of thrombin in both univariate and multivariable analysis: maximum amplitude (Wald 11.78, p < 0.001) and area under the curve (Wald 8.0, p < 0.005), while such associations were not observed for plasmin. In conclusion, this was the first study able to demonstrate the simultaneous evaluation of thrombin and plasmin generation in newly diagnosed untreated cancer patients. Patients with cancer have been observed to exhibit a hypercoagulable profile. During the study, two parameters linked to thrombin generation, MA and AUC, were identified and found to have a potential association with mortality risk. However, no associations were found with parameters related to plasmin generation.
RESUMO
BACKGROUND: Esophageal squamous cell carcinoma (ESCC) shows a 5-year survival rate below 10%, demonstrating the urgency in improving its treatment. Alterations in epidermal growth factor receptors are closely related to malignancy transformation in a number of tumors and recent successful targeted therapies have been directed to these molecules. Therefore, in this study, we analyzed the expression of EGFR and HER2 and evaluated EGFR mutation profile as well as the presence of mutations in hotspots of KRAS and BRAF in ESCC patients. METHODS: We performed RT-qPCR, immunohistochemistry and Fluorescent in situ hybridization to determine EGFR and HER2 expression in ESCC patients, and direct sequencing and PCR-RFLP for mutations and polymorphism analysis. RESULTS: Our results showed an increased EGFR mRNA expression in tumors compared to surrounding tissue (p <0.05), with 11% of the cases presenting at least a four-fold difference between tumor and paired adjacent mucosa. EGFR protein overexpression was present only in 4% of the cases. The median expression of HER2 mRNA was not different between tumors and adjacent mucosa. Still, 7% of the tumors presented at least a 25-fold higher expression of this gene when compared to its paired counterpart. Immunohistochemical analysis revealed that 21% of the tumors were positive for HER2 (scores 2+ and 3+), although only 3+ tumors presented amplification of this gene. Mutation analysis for EGFR (exons 18-21), KRAS (codons 12 and 13) and BRAF (V600E) showed no mutations in any of the hotspots of these genes in almost 100 patients analyzed. EGFR presented synonymous polymorphisms at codon 836 (C>T) in 2.1% of the patients, and at codon 787 (G>A) in 79.2% of the cases. This last polymorphism was also evaluated in 304 healthy controls, which presented a similar frequency (73.7%) in comparison with ESCC patients. The absence of mutations of EGFR, KRAS and BRAF as well as the overexpression of EGFR and HER2 in less than 10% of the patients suggest that this signaling pathway is altered in only a small proportion of patients with ESCC. CONCLUSION: HER receptors target therapies may have the potential to be effective in only a minor fraction of patients with ESCC.

BACKGROUND: Endoscopic treatment of precancerous lesions and early gastric cancer has been widely accepted in recent years. Endoscopic submucosal dissection (ESD), following established indication criteria, can lead to cure of the disease in more than 90% of cases. OBJECTIVE: This study aimed to analyze the use of ESD in patients with early gastric cancer and precancerous lesions, as well as the results of the procedure, its complications and effectiveness in controlling the disease. METHODS: This is a retrospective cohort study composed of 41 patients aged from 53 to 87 years (mean age: 65 years; 58.53% male) who were analyzed from 2008 to 2019. The variables collected from the medical records were: comorbidities, classification of the lesion regarding resection criteria, type of resection, histology, degree of invasion, resection margin, complications, disease recurrence. Statistical analysis was performed using the Kruskal-Wallis test, the McNemar's test, and the Mann-Whitney test, with 5% statistical significance (P<0.05). RESULTS: The most frequent site of the lesion was the gastric antrum and the predominant presentation by the Japanese or Paris classification was the one with depressed components in 56.09%. Adenocarcinoma occurred in 75.6% of the biopsies, and the remainder were adenomas without neoplasia. En-bloc resection occurred in 97.57% of cases, and compromise of the safety margin occurred in one patient. The main pre-existing comorbidity was liver cirrhosis in 29.26% of cases. There was a significant increase in post- ESD adenocarcinoma compared to pre-resection diagnosis. The mean follow-up time was 38.4 months, with one recurrence (2.43%) and two metachronous lesions (4.87%). Complications during and after the procedure occurred in three patients (7.31%), being due to bleeding (two cases) and perforation (one case). There was one death due to a cardiac event not directly related to the procedure. CONCLUSION: Endoscopic submucosal dissection proved to be a safe procedure, with a low complication and recurrence rate. Its recommendation must occur within the established criteria; however, it can be indicated for patients outside the criteria, if there is a high risk for surgical treatment.

AIM: Esophagogastroduodenoscopies and colonoscopies are the main diagnostic examinations for esophageal, stomach, and colorectal tumors. This study aimed to evaluate the estimates of the incidence of esophageal, stomach, and colorectal cancer; population growth; and esophagogastroduodenoscopies and colonoscopies performed by the Unified Health System (SUS), from 2010 to 2018, in the five regions of the country, and to analyze the relationship between these values. RESULTS: The colorectal tumor had a significant elevation, while the esophageal and gastric maintained the incidences. In the five regions, there was a significant increase in the number of colonoscopies; however, this increase did not follow the increase in the population in the North and Northeast regions. There was no significant increase in the number of esophagogastroduodenoscopies in the North, Northeast, Midwest, and South regions, and in the North region there was a decrease. In the Northeast region, there was a decreasing number, and in the South and Midwest regions, the number of examinations remained stable in the period. The Southeast region recorded an increase in the number of examinations following the population growth. CONCLUSION: The current number of esophagogastroduodenoscopies and colonoscopies performed by the SUS did not follow the population growth, in order to attend the population and diagnose esophageal, stomach, and colorectal tumors. Therefore, the country needs to have adequate and strategic planning on how it will meet the demand for these tests and serve the population well, incorporating new technologies.

BACKGROUND: Multimodal therapy with neoadjuvant chemoradiotherapy, followed by esophagectomy has offered better survival results, compared to isolated esophagectomy, in advanced esophageal cancer. In addition, patients who have a complete pathological response to neoadjuvant treatment presented greater overall survival and longer disease-free survival compared to those with incomplete response. AIM: To compare the results of overall survival and disease-free survival among patients with complete and incomplete response, submitted to neoadjuvant chemoradiotherapy, with two therapeutic regimens, followed by transhiatal esophagectomy. METHODS: Retrospective study, approved by the Research Ethics Committee, analyzing the medical records of 56 patients with squamous cell carcinoma of the esophagus, divided into two groups, submitted to radiotherapy (5040 cGY) and chemotherapy (5-Fluorouracil + Cisplatin versus Paclitaxel + Carboplatin) neoadjuvants and subsequently to surgical treatment, in the period from 2005 to 2012, patients. RESULTS: The groups did not differ significantly in terms of gender, race, age, postoperative complications, disease-free survival and overall survival. The 5-year survival rate of patients with incomplete and complete response was 18.92% and 42.10%, respectively (p> 0.05). However, patients who received Paclitaxel + Carboplatin, had better complete pathological responses to neoadjuvant, compared to 5-Fluorouracil + Cisplatin (47.37% versus 21.62% - p = 0.0473, p <0.05). CONCLUSIONS: There was no statistical difference in overall survival and disease-free survival for patients who had a complete pathological response to neoadjuvant. Patients submitted to the therapeutic regimen with Paclitaxel and Carboplastin, showed a significant difference with better complete pathological response and disease progression. New parameters are indicated to clarify the real value in survival, from the complete pathological response to neoadjuvant, in esophageal cancer.

PURPOSE: To investigate the role of omeprazole and nitrites on the gastric mucosa of rats submitted to specific techniques to induce duodenogastric reflux. METHODS: One hundred and twenty Wistar rats were divided into three groups: Group I (n=40) -gastrotomy; Group II (n=40) - duodenogastric reflux after gastrojejunoanastomosis latero-lateral (DGR); Group III (n=40) - retrograde duodenogastric reflux through the pylorus (DGR-P). The groups were divided into 4 subgroups of 10 animals, respectively treated for 16 weeks with water, omeprazole 1.6 mg / rat / day, nitrite 600 mg / kg / day and omeprazole plus nitrite simultaneously. RESULTS: The proliferative lesions found were: squamous hyperplasia - 69.1%, adenomatous hyperplasia in the anastomosis - 29.1% and prepyloric adenomatous hyperplasia - 42.5%. Adenocarcinomas were registered in 7 animals (5.8%): one in Group I (omeprazole plus nitrite), two in Group II (omeprazole and nitrite plus omeprazole) and four in Group III (water, nitrite, omeprazole and omeprazole plus nitrite). CONCLUSIONS: The occurrence of squamous hyperplasia, adenomatous hyperplasia and adenocarcinoma increased after gastrojejunal anastomoses, which cause duodenogastric reflux. The association of omeprazole did not protect the development of proliferative lesions and cancer induced by duodenogastric reflux in rats.

PURPOSE: Esophageal squamous cell cancer (ESCC) is still associated with a dismal prognosis. However, surgical series have shown that high-volume hospitals have better outcomes and that the impact of center volume on definitive chemoradiotherapy (dCRT) or CRT plus surgery (CRT + S) remains unknown. METHODS: We performed a retrospective analysis of patients with locally advanced stage II-III (non-T4) ESCC treated with dCRT or CRT + S in São Paulo state, Brazil. Descriptive variables were assessed with the χ2 test after categorization of hospital volume (high-volume [HV] center, top 5 higher volume, or low-volume [LV] center). Overall survival (OS) was assessed with Kaplan-Meier curves, log-rank tests, and Cox proportional hazards. Finally, an interaction test between each facility's treatments was performed. RESULTS: Between 2000 and 2013, 1,347 patients were analyzed (77% treated with dCRT and 65.7% in HV centers) with a median follow-up of 23.7 months. The median OS for dCRT was 14.1 months (95% CI, 13.3 to 15.3 months) and for CRT + S, 20.6 months (95% CI, 16.1 to 24.9 months). In the multivariable analysis, dCRT was associated with worse OS (hazard ratio [HR], 1.38; 95% CI, 1.19 to 1.61; P < .001) compared with CRT + S. HV hospitals were associated with better OS (HR, 0.82; 95% CI, 0.71 to 0.94; P = .004) compared with LV hospitals. Importantly, CRT + S superiority was restricted to HV hospitals (dCRT v CRT + S: HR, 1.56; 95% CI, 1.29 to 1.89; P < .001), while in LV hospitals, there was no statistically significant difference (HR, 1.23; 95% CI, 0.88 to 1.43; P = .350), with a significant interaction test (Pinteraction = .035). CONCLUSION: Our data show that CRT + S is superior to dCRT in the treatment of ESCC exclusively in HV hospitals, which favors the literature trend to centralize the treatment of ESCC in HV centers.

BACKGROUND: Gastric volvulus is a rare condition, characterized by abnormal rotation of the stomach, causing obstruction with risk of ischemia, necrosis, and perforation. It is associated with high morbidity and mortality rates and, as it is life threatening, early diagnosis and treatment are crucial. METHODS: Retrospective study of medical records of intrathoracic gastric volvulus patients treated by video-laparoscopy from January 2000 to December 2018, in a University Hospital. RESULTS: Thirty patients (34 surgical procedures - 4 re-operations), 9 (30%) male and 21 (70%) female. The mean age was 57.65 ± 32.65 and the mean body mass index was 27.11 ± 3.5 kg/m2. The most prevalent symptoms were epigastric pain and dysphagia. In 41.17% of the cases, the contrast X-ray confirmed the diagnosis. All 34 cases were intrathoracic volvulus, 24 of which were organo-axial (70.58%). The surgical technique used was hiatoplasty, without mesh (25 cases; 73.52%) and with reinforcement mesh (9 cases; 26.47%), mostly associated with Nissen fundoplication (52.94%). The mean surgical time was 215.7 ± 62.9 minutes, with conversion in 5 cases (15.62%). Hospitalization ranged from 4 ± 2 days. There was no record of operative mortality, and symptom improvement occurred in 100% of patients. The mean follow-up time for patients was 41.8 ± 32.6 months. CONCLUSIONS: Surgical treatment should be indicated to reduce morbidity and mortality, and associated with improved symptoms and patient prognosis. Video-laparoscopic surgery on intrathoracic gastric volvulus proved to be safe and effective and should be the option of choice in the management of this disease.

OBJECTIVE: to analyze the surgical treatment of patients with recurrent megaesophagus followed at the esophageal-stomach-duodenal outpatient clinic of the Hospital de Clínicas - UNICAMP. METHODS: a retrospective study, from 2011 to 2017, with 26 patients with Chagas or idiopathic megaesophagus, surgically treated, and who recurred with dysphagia. Clinical, endoscopic and radiographic aspects were assessed and correlated with the performed surgical procedures. RESULTS: 50% had dysphagia for liquids, 69% regurgitation, 65.3% heartburn, 69.2% weight loss and 69.2% had Chagas disease. In addition, 38.4% had megaesophagus stage 1 and 2 and 61.5% stage 3 and 4. Regarding the reoperations, 53% of them underwent Heller-Pinotti surgery by laparoscopy, Serra-Dória in 30.7% and esophageal mucosectomy in 7.9%. In 72% of the reoperations there were no postoperative complications, and 80% of the patients had a good outcome, with reduction or elimination of dysphagia. Among the reoperated patients undergoing the laparoscopic Heller-Pinotti technique, three reported little improvement of dysphagia in the postoperative period and among those who underwent Serra-Dória surgery, 100% had no dysphagia. It was observed that, when the time between the first procedure and the reoperation was longer, the better the surgical result was, with statistical significant decreased dysphagia (p=0.0013, p<0.05). CONCLUSIONS: there was a preference to perform laparoscopic re-miotomy and, as a second option, Serra-Dória surgery, for patients with recurrent megaesophagus. Esophagectomy or esophageal mucosectomy were reserved for more severe patients.

BACKGROUND: Since the publication of the first Brazilian Consensus on Gastric Cancer (GC) in 2012 carried out by the Brazilian Gastric Cancer Association, new concepts on diagnosis, staging, treatment and follow-up have been incorporated. AIM: This new consensus is to promote an update to professionals working in the fight against GC and to provide guidelines for the management of patients with this condition. METHODS: Fifty-nine experts answered 67 statements regarding the diagnosis, staging, treatment and prognosis of GC with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree A consensus was adopted when at least 80% of the sum of the answers "fully agree" and "partially agree" was reached. This article presents only the responses of the participating experts. Comments on each statement, as well as a literature review, will be presented in future publications. RESULTS: Of the 67 statements, there was consensus in 50 (74%). In 10 declarations, there was 100% agreement. CONCLUSION: The gastric cancer treatment has evolved considerably in recent years. This consensus gathers consolidated principles in the last decades, new knowledge acquired recently, as well as promising perspectives on the management of this disease.

BACKGROUND: The II Brazilian Consensus on Gastric Cancer by the Brazilian Gastric Cancer Association (ABCG) was recently published. On this occasion, several experts in gastric cancer expressed their opinion before the statements presented. AIM: To present the ABCG Guidelines (part 1) regarding the diagnosis, staging, endoscopic treatment and follow-up of gastric cancer patients. METHODS: To forge these Guidelines, the authors carried out an extensive and current review regarding each statement present in the II Consensus, using the Medline/PubMed, Cochrane Library and SciELO databases with the following descriptors: gastric cancer, staging, endoscopic treatment and follow-up. In addition, each statement was classified according to the level of evidence and degree of recommendation. RESULTS: Of the 24 statements, two (8.3%) were classified with level of evidence A, 11 (45.8%) with B and 11 (45.8%) with C. As for the degree of recommendation, six (25%) statements obtained grade of recommendation 1, nine (37.5%) recommendation 2a, six (25%) 2b and three (12.5%) grade 3. CONCLUSION: The guidelines presented here are intended to assist professionals working in the fight against gastric cancer with relevant and current information, granting them to be applied in the daily medical practice.

BACKGROUND: The treatment of advanced gastric cancer with curative intent is essentially surgical and chemoradiotherapy is indicated as neo or adjuvant to control the disease and prolong survival. AIM: To assess the survival of patients undergoing subtotal or total gastrectomy with D2 lymphadenectomy followed by adjuvant chemoradiotherapy. METHODS: Were retrospectively analyzed 87 gastrectomized patients with advanced gastric adenocarcinoma, considered stages IB to IIIC and submitted to adjuvant chemoradiotherapy (protocol INT 0116). Tumors of the esophagogastric junction, with peritoneal implants, distant metastases, and those that had a compromised surgical margin or early death after surgery were excluded. They were separated according to the extention of the gastrectomy and analyzed for tumor site and histopathology, lymph node invasion, staging, morbidity and survival. RESULTS: The total number of patients who successfully completed the adjuvant treatment was 45 (51.7%). Those who started treatment and discontinued due to toxicity, tumor-related worsening, or loss of follow-up were 10 (11.5%) and reported as incomplete adjuvant. The number of patients who refused or did not start adjuvant treatment was 33 (48.3%). Subtotal gastrectomy was indicated in 60 (68.9%) and total in 27 (31.1%) and this had a shorter survival. The mean resected lymph nodes was 30.8. Staging and number of lymph nodes affected were predictors of worse survival and the more advanced the tumor. Patients undergoing adjuvant therapy with complete chemoradiotherapy showed a longer survival when compared to those who did it incompletely or underwent exclusive surgery. On the other hand, comparing the T4b (IIIB + IIIC) staging patients who had complete adjuvance with those who underwent the exclusive operation or who did not complete the adjuvant, there was a significant difference in survival. CONCLUSION: Adjuvant chemoradiotherapy presents survival gain for T4b patients undergoing surgical treatment with curative intent.

BACKGROUND: The early postoperative period is critical for surgical patients. SOFA, SAPS 3 and APACHE II are prognostic scores widely used to predict mortality in ICU patients. This study aimed to evaluate these index tests for their prognostic accuracy for intra-ICU and in-hospital mortalities as target conditions in patients admitted to ICU after urgent or elective surgeries and to test whether they aid in decision-making. The process comprised the assessment of discrimination through analysis of the areas under the receiver operating characteristic curves and calibration of the prognostic models for the target conditions. After, the clinical relevance of applying them was evaluated through the measurement of the net benefit of their use in the clinical decision. RESULTS: Index tests were found to discriminate regular for both target conditions with a poor calibration (C statistics-intra-ICU mortality AUROCs: APACHE II 0.808, SAPS 3 0.821 and SOFA 0.797/in-hospital mortality AUROCs: APACHE II 0.772, SAPS 3 0.790 and SOFA 0.742). Calibration assessment revealed a weak correlation between the observed and expected number of cases in several thresholds of risk, calculated by each model, for both tested outcomes. The net benefit analysis showed that all score's aggregate value in the clinical decision when the calculated probabilities of death ranged between 10 and 40%. CONCLUSIONS: In this study, we observed that the tested ICU prognostic scores are fair tools for intra-ICU and in-hospital mortality prediction in a cohort of postoperative surgical patients. Also, they may have some potential to be used as ancillary data to support decision-making by physicians and families regarding the level of therapeutic investment and palliative care.
