RESUMO

BACKGROUND: With the development of endoscopic technology, endoscopic submucosal dissection (ESD) has been widely used in the treatment of gastrointestinal tumors. It is necessary to evaluate the depth of tumor invasion before the application of ESD. The convolution neural network (CNN) is a type of artificial intelligence that has the potential to assist in the classification of the depth of invasion in endoscopic images. This meta-analysis aimed to evaluate the performance of CNN in determining the depth of invasion of gastrointestinal tumors. METHODS: A search on PubMed, Web of Science, and SinoMed was performed to collect the original publications about the use of CNN in determining the depth of invasion of gastrointestinal neoplasms. Pooled sensitivity and specificity were calculated using an exact binominal rendition of the bivariate mixed-effects regression model. I2 was used for the evaluation of heterogeneity. RESULTS: A total of 17 articles were included; the pooled sensitivity was 84% (95% CI, 0.81-0.88), specificity was 91% (95% CI, 0.85-0.94), and the area under the curve (AUC) was 0.93 (95% CI, 0.90-0.95). The performance of CNN was significantly better than that of endoscopists (AUC: 0.93 vs 0.83, respectively; P = .0005). CONCLUSION: Our review revealed that CNN is one of the most effective methods of endoscopy to evaluate the depth of invasion of early gastrointestinal tumors, which has the potential to work as a remarkable tool for clinical endoscopists to make decisions on whether the lesion is feasible for endoscopic treatment.

RESUMO

PURPOSE: Improvement of patient care is associated with increasing publication numbers in biomedical research. However, such increasing numbers of publications make it challenging for physicians and scientists to screen and process the literature of their respective fields. In this study, we present a comprehensive bibliometric analysis of the evolution of gastrointestinal stromal tumor (GIST) research, analyzing the current state of the field and identifying key open questions going beyond the recent advantages for future studies to assess. METHODS: Using the Web of Science Core Collection, 5040 GIST-associated publications in the years 1984-2022 were identified and analyzed regarding key bibliometric variables using the Bibliometrix R package and VOSviewer software. RESULTS: GIST-associated publication numbers substantially increased over time, accentuated from year 2000 onwards, and being characterized by multinational collaborations. The main topic clusters comprise surgical management, tyrosine kinase inhibitor (TKI) development/treatment, diagnostic workup, and molecular pathophysiology. Within all main topic clusters, a significant progress is reflected by the literature over the years. This progress ranges from conventional open surgical techniques over minimally invasive, including robotic and endoscopic, resection techniques to increasing identification of specific functional genetic aberrations sensitizing for newly developed TKIs being extensively investigated in clinical studies and implemented in GIST treatment guidelines. However, especially in locally advanced, recurrent, and metastatic disease stages, surgery-related questions and certain specific questions concerning (further-line) TKI treatment resistance were infrequently addressed. CONCLUSION: Increasing GIST-related publication numbers reflect a continuous progress in the major topic clusters of the GIST research field. Especially in advanced disease stages, questions related to the interplay between surgical approaches and TKI treatment sensitivity should be addressed in future studies.

RESUMO

The advancement of comprehensive treatment has allowed an increasing number of patients with gastrointestinal tumor to achieve long-term survival. In current clinical practice, there is a growing population of patients with advanced gastrointestinal tumor. Due to various factors, such as tumor burden, treatments including chemotherapy and radiation therapy, as well as underlying diseases, patients with advanced gastrointestinal tumor often experience malnutrition, which negatively impacts their clinical outcomes. The mechanism of malnutrition in patients with advanced gastrointestinal tumor is complex, and conventional nutritional support therapy has shown limited effectiveness. With the continuous progress in the concept and technique of nutritional support therapy, the diversification of treatment strategies, and the strengthening of multidisciplinary collaboration, the nutritional management for patients with advanced gastrointestinal tumor tends to be standardized and rational, leading to effective improvement in patients' nutritional status and clinical outcomes. Based on the latest evidence-based medicine, combined with the author's practical experience and insights, this article aims to explore nutritional support therapy for patients with advanced gastrointestinal tumor.

RESUMO

El tumor neuroectodérmico maligno del tracto gastrointestinal es una neoplasia rara con pocos casos reportados en la literatura, especialmente en América Latina. Descrito por primera vez en 2003, se trata de una entidad sin tratamiento estandarizado y de pobre pronóstico. Se presenta el caso de una paciente de 22 años de edad que acude a la consulta por dolor abdominal, anemia y masa abdominal palpable. Luego de estudios pertinentes se decide la conducta resectiva y el posterior tratamiento oncológico. (AU)


Malignant gastrointestinal neuroectodermal tumor (GNET), formerly known as clear cell sarcoma of the gastrointestinal tract, is an extremely rare tumor of mesenchymal origin, which presents great microscopic and molecular similarity to clear cell sarcoma found in other parts of the body, such as tendons and aponeurosis. It is characterized by its rapid evolution, high recurrence rate and frequent diagnosis as metastatic disease.1,2 (AU)

RESUMO

BACKGROUND: In recent years, the incidence of gastrointestinal neuroendocrine tumors (GI-NETs) has remarkably increased due to the widespread use of screening gastrointestinal endoscopy. Currently, the most common treatments are surgery and endoscopic resection. Compared to surgery, endoscopic resection possesses a higher risk of resection margin residues for the treatment of GI-NETs. METHODS: A total of 315 patients who underwent surgery or endoscopic resection for GI-NETs were included. We analyzed their resection modality (surgery, ESD, EMR), margin status, Preoperative marking and Prognosis. RESULTS: Among 315 patients included, 175 cases underwent endoscopic resection and 140 cases underwent surgical treatment. A total of 43 (43/175, 24.57%) and 10 (10/140, 7.14%) patients exhibited positive resection margins after endoscopic resection and surgery, respectively. Multivariate regression analysis suggested that no preoperative marking and endoscopic treatment methods were risk factors for resection margin residues. Among the patients with positive margin residues after endoscopic resection, 5 patients underwent the radical surgical resection and 1 patient underwent additional ESD resection. The remaining 37 patients had no recurrence during a median follow-up of 36 months. CONCLUSIONS: Compared with surgery, endoscopic therapy has a higher margin residual rate. During endoscopic resection, preoperative marking may reduce the rate of lateral margin residues, and endoscopic submucosal dissection may be preferred than endoscopic mucosal resection. Periodical follow-up may be an alternative method for patients with positive margin residues after endoscopic resection.

RESUMO

BACKGROUND: The incidence of second primary malignancy is increasing. However, although there is some information on second primary esophageal cancer (SPEC) itself, there is no study or guideline on the use of surgery for SPEC after gastrointestinal cancer (SPEC-GC). Thus, this study aimed to gather evidence for the benefits of surgery by analyzing a national cohort and determining the prognostic factors and clinical treatment decisions for SPEC-GC. METHODS: Data for patients with SPEC-GC were obtained from the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2019. The prognostic factors of SPEC-GC were investigated by stepwise Cox proportional hazards regression and Kaplan-Meier analyses for overall survival and cancer-specific survival. RESULTS: A total of 8308 patients with SPEC were selected, including 582 patients with SPEC-GC. Multivariate analysis revealed that surgery, year of diagnosis, scope of regional lymph node surgery, tumor differentiation grade, SEER historic stage, and triple therapy were significant predictors of survival outcomes (P < .05). Surgery seemed to improve the prognosis of patients with SPEC-GC significantly compared with no surgery and chemoradiotherapy (P < .001). CONCLUSIONS: Surgery should be considered as the main treatment for SPEC-GC. Surgery, year of diagnosis, scope of regional lymph node surgery, tumor differentiation grade, SEER historic stage, and triple therapy were found to be independent prognostic factors for these patients. These factors should be considered in the clinical diagnosis and treatment of SPEC-GC.

RESUMO

Precision medicine is used to treat gastrointestinal malignancies including esophageal, gastric, small bowel, colorectal, and pancreatic cancers. Cutting-edge assays to detect and treat these cancers are active areas of research and will soon become standard of care. Colorectal cancer is a prime example of precision oncology as disease site is no longer the final determinate of treatment. Here, the authors describe how leveraging an understanding of tumor biology translates to individualized patient care using evidence-based practices.

RESUMO

AIM: Evidence shows that early mobilization according to the Enhanced Recovery After Surgery guideline promotes postoperative recovery in gastrointestinal cancer patients undergoing gastrointestinal surgery. However, compliance with the guideline in clinical settings remains low. This study aimed to investigate the factors influencing early mobilization after surgery. METHODS: A prospective research design was used. Data from 470 patients with gastrointestinal cancer who underwent gastrointestinal surgery between February 2021 and July 2022 were collected. RESULTS: More than half (53.6%) of the patients met the criteria for early mobilization. Females (odds ratio [OR], 1.53; 95% confidence interval [CI], 1.02-2.29), age 〉70 years (OR, 1.76; 95% CI, 1.09-2.86), low level of education (OR, 1.98; 95% CI, 1.12-3.95), and ≥4 catheters (OR, 1.86; 95% CI, 1.25-2.76) were barriers to early mobilization. CONCLUSIONS: Sex, age, education, and the number of catheters were found to be significant factors associated with non-early mobilization after gastrointestinal surgery.

RESUMO

BACKGROUND: With the development of enhanced recovery after surgery, early oral feeding is likely to become the preferred mode of nutrition after surgery for upper gastrointestinal tract malignancies. However, the optimal time to initiate early oral feeding remains unknown. OBJECTIVE: We aimed to compare the effects of different introduction times of early oral feeding in patients with upper gastrointestinal malignancies in terms of safety, tolerance, and effectiveness and to identify the optimal time for early oral feeding after surgery. METHODS: A random-effects meta-analysis was performed to identify evidence from relevant randomized controlled trials. Ten electronic databases were searched for randomized controlled trials from their earliest records to May 2023. Data were analyzed using the Stata 16.0 software. RESULTS: A total of 22 randomized controlled trials including 2510 patients and seven time points for oral feeding after surgery were considered. Regarding safety, oral feeding initiated on postoperative day 3 may be the safest (high-quality evidence) compared with other times. Regarding tolerance, oral feeding initiated on postoperative day 5 may be the most well-tolerated (moderate-quality evidence) compared with other times. Regarding effectiveness, oral feeding initiated on postoperative day 3 may be the most effective (moderate-quality evidence) compared with other times. CONCLUSIONS: Early oral feeding is safe, tolerable, and effective in postoperative patients with upper gastrointestinal malignancies. The optimal time to initiate early oral feeding after surgery was most likely postoperative day 3. The results of this meta-analysis provide evidence-based guidelines for clinical decision-making.

RESUMO

Liver transplantation (LT) has emerged as a standard of care for patients with end-stage liver disease, providing a life-saving intervention for patients with severely compromised liver function in both the acute and chronic setting. While LT has also become a routine procedure for early-stage hepatocellular carcinoma (HCC), offering a potential cure by treating both the tumor and the underlying liver disease, its relevance in the context of other malignancies such as cholangiocellular carcinoma (CCA), combined hepatocellular-cholangiocarcinoma (cHCC-CCA) or liver metastases is still the subject of intense debate and no definite recommendations have yet been established. This review summarizes the current therapeutic standards in the context of LT for gastrointestinal malignancies and provides a reflection and outlook on current scientific and clinical developments.

RESUMO

OBJECTIVES: Blue rubber bleb nevus syndrome (BRBNS) is a rare challenging cause of gastrointestinal bleeding. We performed a systematic review of case reports and case series on BRBNS to gather information on the treatment options currently available. METHODS: All studies reporting a case of BRBNS in humans were evaluated. Papers were ruled out if CARE criteria and explanations on patient's selection, ascertainment, causality, and reporting were not respected or identified. PROSPERO 2021 CRD 42021286982. RESULTS: Blue rubber bleb nevus syndrome was treated in 106 cases from 76 reports. 57.5% of the population was under 18 years old, and up to 50% of the cases reported a previous treatment. Clinical success was achieved in 98 patients (92.4%). Three main types of interventions were identified: systemic drug therapy, endoscopy, and surgery. After BRBNS recurrence or previous therapy failure, systemic drug therapy emerged as a preferred second-line treatment over endoscopy (P = 0.01), but with a higher rate of reported adverse events when compared with surgery and endoscopy (P < 0.001). Endoscopic treatment was associated with a higher number of required sessions to achieve complete eradication when compared with surgery (P < 0.001). No differences between the three main areas were found in the overall follow-up time (P = 0.19) or in the recurrence rate (P = 0.45). CONCLUSION: Endoscopy, surgery, and systemic drug therapy are feasible treatment options for BRBNS. Systemic drug therapy was the favorite second-line treatment after endoscopic failure or recurrence of BRBNS, but adverse events were more frequently reported.

RESUMO

OBJECTIVE: The 6-min walk test (6MWT) is a simple and valid method to evaluate cardiopulmonary function. We performed this prospective study in patients undergoing laparoscopic gastrointestinal cancer surgery to explore the association between preoperative 6MWT performance and overall postoperative complications. METHODS: This study was registered at clinicaltrials.gov (NCT03711526). The study consecutively enrolled patients receiving laparoscopic gastrointestinal cancer surgery in our institution. All patients performed the 6MWT upon recruitment and received 30 days of postoperative follow-up. The primary outcome was overall complications, defined by ≥ grade I Clavien-Dindo (CD) classification (2004) complications. Multivariable logistic regression was used to test the association of 6-min walk distance (6MWD) with the outcome. RESULTS: A total of 184 patients were included in the final analyses. In the 37 (20.1 %) patients with overall complications, the mean (standard deviation) preoperative 6MWD was 469.1 (86.8) m. In patients with no complications, the 6MWD was 502.6 (90.2) m. The mean difference was 33.5 m (95 % confidence interval, 1.3, 65.7; P = 0.042). A longer preoperative 6MWD was associated with a lower odds of developing postoperative complications (odds ratio, 0.994 per meter increase; 95 % confidence interval, 0.989, 0.999; p = 0.023). CONCLUSION: This study indicated an association between the preoperative 6MWD and postoperative complications in patients undergoing laparoscopic gastrointestinal cancer surgery.

RESUMO

Nutrition impact symptoms and unintended weight loss are prevalent in patients with gastrointestinal cancers, especially during the perioperative period or while prescribed anticancer treatments. Because patients may experience loss of lean body mass and malnutrition, aggressive nutrition intervention prior to surgery should be considered. Cancer prehabilitation is a process spanning the care continuum from diagnosis to the time of surgery encompassing nutrition support, psychological and physical assessment, and targeted interventions. Thirteen studies published between 2013 and 2023 were included in this review and evaluated prehabilitation programs' impact on postoperative outcomes in patients with gastrointestinal cancers. Literature continues to emerge supporting the integration of nutrition into a prehabilitation program because of its potential to contribute to improved clinical outcomes, quality of life, and cost-effectiveness, but considerable variation exists with respect to the specific recommendations provided by current prehabilitation programs.

RESUMO

OBJECTIVES: The value of multidisciplinary tumor boards (MTBs) in the treatment of gastrointestinal cancer patients is well known. Most of the current evidence focuses on advanced cancer cases, whereas little is known about the effect of MTBs on early tumors, especially after endoscopic resection. The aim of our study is to evaluate the value of the MTB after endoscopic resection of malignant tumors of the gastrointestinal tract. METHODS: We retrospectively analyzed all endoscopically resected malignant tumors in our department between 2011 and 2019, focusing on the existence of an MDT recommendation after endoscopic resection, the MDT adherence to the current guidelines, and the implementation of the recommendation by the patients. RESULTS: We identified 198 patients fulfilling our inclusion criteria, of whom 168 (85%) were discussed in the MDT after endoscopic resection. In total, 155 of the recommendations (92%) were in accordance with the current guidelines, and 147 (88%) of them were implemented by the patients. The MDT discussion itself did not influence the overall survival, whereas the implementation of the MTB recommendation was associated with a significantly better prognosis. Deviations of the MDT recommendation from the guidelines had no effect on the overall survival. CONCLUSIONS: The discussion of endoscopically resected malignant tumors in the MTB is crucial for the treatment of patients with this type of cancer, since the implementation of the MTB recommendation, even if it deviates from the current guidelines, improves the prognosis.

RESUMO

OBJECTIVE: To clarify whether perioperative immunonutrition is effective in adult patients with or without malnutrition undergoing elective surgery for head and neck (HAN) or gastrointestinal (GI) cancers. BACKGROUND: It is important to avoid postoperative complications in patients with cancer as they can compromise clinical outcomes. There is no consensus on the efficacy of perioperative immunonutrition in patients with or without malnutrition undergoing HAN or GI cancer surgery. MATERIALS AND METHODS: We searched MEDLINE (PubMed), MEDLINE (OVID), EMBASE, Cochrane Central Register of Controlled Trials, Web of Science Core Selection, and Emcare from 1981 to 2022 using search terms related to immunonutrition and HAN or GI cancer. We included randomized controlled trials. Intervention was defined as immunonutritional therapy including arginine, n-3 omega fatty acids, or glutamine during the perioperative period. The control was defined as standard nutritional therapy. The primary outcomes were total postoperative and infectious complications, defined as events with a Clavien-Dindo classification grade ≥ II that occurred within 30 days after surgery. RESULTS: Of the 4825 patients from 48 included studies, 19 had upper GI cancer, 9 had lower, and 8 had mixed cancer, whereas 12 had HAN cancers. Immunonutrition reduced the total postoperative complications (relative risk ratio: 0.78; 95% CI, 0.66-0.93; certainty of evidence: high) and infectious complications (relative risk ratio: 0.71; 95% CI, 0.61-0.82; certainty of evidence: high) compared with standard nutritional therapy. CONCLUSIONS: Nutritional intervention with perioperative immunonutrition in patients with HAN and GI cancers significantly reduced total postoperative complications and infectious complications.

RESUMO

OBJECTIVES: Muscle weakness, assessed by grip strength, has been shown to predict postoperative mortality in older patients with cancer. Because lower extremity muscle strength well reflects physical performance, we examined whether lower knee extension muscle strength predicts postoperative mortality better than grip strength in older patients with gastrointestinal cancer. DESIGN: Prospective, observational study in a single institution. SETTING AND PARTICIPANTS: A total of 813 patients (79.0 ± 4.2 years, 66.5% male) aged 65 years or older with gastrointestinal cancer who underwent preoperative evaluation of grip strength and isometric knee extension muscle strength between April 2012 and April 2019 were included. METHODS: The study participants were prospectively followed up for postoperative mortality. Muscle weakness was defined as the lowest quartile of grip strength or knee extension strength (GS-muscle weakness and KS-muscle weakness, respectively). RESULTS: Among the study participants, 176 patients died during a median follow-up of 716 days. In the Kaplan-Meier analysis, we found that patients with both GS-muscle weakness and KS-muscle weakness had a lower survival rate than those without muscle weakness. As expected, higher clinical stages and abdominal and thoracic surgeries compared with endoscopic surgery were associated with increased all-cause mortality. In addition, we found that KS-muscle weakness, but not GS-muscle weakness, was an independent prognostic factor after adjusting for sex, body mass index, cancer stage, surgical technique, and surgical site in the Cox proportional hazard model. CONCLUSIONS AND IMPLICATIONS: In older patients with gastrointestinal cancer, muscle weakness based on knee extension muscle strength can be a better predictor of postoperative prognosis than muscle weakness based on grip strength.

RESUMO

PURPOSE: A positive circumferential resection margin (CRM) for oesophageal and gastric carcinoma is associated with local recurrence and poorer long-term survival. Diffuse reflectance spectroscopy (DRS) is a non-invasive technology able to distinguish tissue type based on spectral data. The aim of this study was to develop a deep learning-based method for DRS probe detection and tracking to aid classification of tumour and non-tumour gastrointestinal (GI) tissue in real time. METHODS: Data collected from both ex vivo human tissue specimen and sold tissue phantoms were used for the training and retrospective validation of the developed neural network framework. Specifically, a neural network based on the You Only Look Once (YOLO) v5 network was developed to accurately detect and track the tip of the DRS probe on video data acquired during an ex vivo clinical study. RESULTS: Different metrics were used to analyse the performance of the proposed probe detection and tracking framework, such as precision, recall, mAP 0.5, and Euclidean distance. Overall, the developed framework achieved a 93% precision at 23 FPS for probe detection, while the average Euclidean distance error was 4.90 pixels. CONCLUSION: The use of a deep learning approach for markerless DRS probe detection and tracking system could pave the way for real-time classification of GI tissue to aid margin assessment in cancer resection surgery and has potential to be applied in routine surgical practice.

RESUMO

Introdução: O primeiro sistema robótico utilizado em procedimentos cirúrgicos foi desenvolvido em 1994. Os primeiros pacientes do Sistema Único de Saúde do Brasil (SUS) foram beneficiados com essa tecnologia apenas a partir de 2012, após a instalação da plataforma robótica no Instituto Nacional de Câncer (INCA). Esse estudo avalia 10 anos de experiência do programa robótico na referida instituição. Método: Todos os procedimentos robóticos realizados pelo serviço de cirurgia abdominopélvica dessa instituição entre julho de 2012 a dezembro de 2022 foram analisados. Os dados foram coletados a partir do banco de dados do programa de robótica e por revisão de prontuários físicos e eletrônicos. Resultados: Foram realizados 280 procedimentos cirúrgicos robóticos. A maioria dos casos operados foi conduzida pelo grupo de cirurgia colorretal, correspondendo a 87,5% do total, sendo a ressecção anterior de reto a cirurgia mais realizada. Os demais casos foram operados pelo grupo hepatobiliar (4,6%), estômago (4,2%) e esôfago (3,6%). A taxa de conversão para cirurgia aberta foi de 10,3%. O período médio de internação foi inferior a 10 dias e 9,6% dos pacientes apresentaram reinternação dentro de 90 dias após a cirurgia. Do total, 43,5% dos pacientes foram submetidos a tratamento neoadjuvante com quimioterapia e/ou radioterapia. Durante o período analisado, 18,5% dos pacientes evoluíram com recidiva de doença, sendo a sobrevida global em 5 anos de aproximadamente 60%. Conclusão: Nos últimos 10 anos o uso da tecnologia robótica cresceu significativamente, promovendo melhora dos resultados clínicos. O programa de cirurgia robótica do INCA para tratamento do câncer foi o pioneiro no âmbito nacional dentro do SUS e possibilitou a divulgação e consolidação desta excelente ferramenta tecnológica no tratamento do câncer gastrointestinal. Os resultados apresentados revelam o êxito do programa, demonstrando taxa de complicações aceitável, tempo de internação reduzido e resultados oncológicos satisfatórios, disponibilizando aos pacientes do SUS tratamento cirúrgico atualizado e eficaz.


Introduction: The first robotic system used in surgical procedures was developed in 1994. In 2012, the first robotic surgeries were performed in the Brazilian Public Health System (Sistema Único de Saúde - SUS), after the installation of the robotic platform at Brazilian National Cancer Institute (INCA). This study evaluates 10 years of experience with the robotic program at this Center. Method: All robotic procedures performed by the abdomino-pelvic surgery service of this center between july 2012 and december 2022 were reviewed. Data were collected from the database of the robotics program and review of physical and electronic medical records. Results: 280 robotic surgical procedures were performed. Most cases were conducted by the colorectal surgery group, corresponding to 87.5% of the cases, with anterior resection of the rectum being the most common procedure. The remaining cases were operated by the hepatobiliary group (4.6%), stomach group (4.2%) and esophagus group (3.6%). The conversion rate to open surgery was 10.3%. The average length of stay was less than 10 days and 9.6% of patients were readmitted within 90 days following surgery. Of all, 43.5% of the patients underwent neoadjuvant treatment with chemotherapy and/or radiotherapy. During the analyzed period, 18.5% of the patients had disease recurrence, with an overall 5-year survival of approximately 60%. Conclusion: In the last 10 years, the use of robotic technology has grown significantly, promoting improved clinical outcomes. INCA's robotic surgery program was a pioneer on the national scene within the SUS and enabled the dissemination and consolidation of this excellent technological tool in treatment of gastrointestinal cancer. The results presented reveal the success of the program, demonstrating an acceptable complication rate, reduced length of stay and satisfactory oncological results, providing SUS patients with updated and effective surgical treatment
