ABSTRACT

ABSTRACT Introduction: Minimally invasive surgery widely used to treat benign disorders of the digestive system, has become the focus of intense study in recent years in the field of surgical oncology. Since then, the experience with this kind of approach has grown, aiming to provide the same oncological outcomes and survival to conventional surgery. Regarding gastric cancer, surgery is still considered the only curative treatment, considering the extent of resection and lymphadenectomy performed. Conventional surgery remains the main modality performed worldwide. Notwithstanding, the role of the minimally invasive access is yet to be clarified. Objective: To evaluate and summarize the current status of minimally invasive resection of gastric cancer. Methods: A literature review was performed using Medline/PubMed, Cochrane Library and SciELO with the following headings: gastric cancer, minimally invasive surgery, robotic gastrectomy, laparoscopic gastrectomy, stomach cancer. The language used for the research was English. Results: 28 articles were considered, including randomized controlled trials, meta-analyzes, prospective and retrospective cohort studies. Conclusion: Minimally invasive gastrectomy may be considered as a technical option in the treatment of early gastric cancer. As for advanced cancer, recent studies have demonstrated the safety and feasibility of the laparoscopic approach. Robotic gastrectomy will probably improve outcomes obtained with laparoscopy. However, high cost is still a barrier to its use on a large scale.


RESUMO Introdução: A cirurgia minimamente invasiva amplamente usada para tratar doenças benignas do aparelho digestivo, tornou-se o foco de intenso estudo nos últimos anos no campo da oncologia cirúrgica. Desde então, a experiência com este tipo de abordagem tem crescido, com o objetivo de fornecer os mesmos resultados oncológicos e sobrevivência à cirurgia convencional. Em relação ao câncer gástrico, o tratamento cirúrgico ainda é considerado o único tratamento curativo, considerando a extensão da ressecção e linfadenectomia realizada. A gastrectomia convencional continua a ser a principal modalidade realizada em todo o mundo. Não obstante, o papel do acesso minimamente invasivo tem ainda de ser esclarecido. Objetivo: Avaliar e resumir o estado atual da ressecção minimamente invasiva do câncer gástrico. Método: Foi realizada revisão da literatura utilizando as bases Medline/PubMed, Cochrane Library e SciELO com os seguintes descritores: câncer gástrico, cirurgia minimamente invasiva, gastrectomia robótica, gastrectomia laparoscópica, neoplasia de estômago. A língua usada para a pesquisa foi o inglês. Resultados: Foram considerados para elaboração desta revisão 28 artigos, entre eles ensaios clínicos randomizados, metanálises, estudos coorte prospectivos e retrospectivos. Conclusão: A gastrectomia minimamente invasiva é opção técnica no tratamento do câncer gástrico precoce. Quanto ao câncer avançado, estudos recentes têm demonstrado a segurança e a viabilidade do acesso videolaparoscópico. A gastrectomia robótica provavelmente melhorará os resultados obtidos com a laparoscopia. Porém, o alto custo ainda é impedimento para sua utilização em larga escala.

ABSTRACT

Objetivo: caracterizar a los pacientes con cáncer gástrico y precisar su evolución con el tratamiento indicado. Métodos: se realizó un estudio observacional, descriptivo de 50 pacientes con diagnóstico de cáncer gástrico en el municipio Caimito durante 15 años. Las variables estudiadas fueron: edad, sexo, antecedentes patológicos personales de enfermedad gástrica, antecedentes familiares, laborales, nutricionales y de exposición a tóxicos y evolución según tratamiento indicado. Resultados: el mayor número de pacientes diagnosticados y fallecidos corresponden a los consejos populares Caimito y Costa Norte. Hubo 32 pacientes del sexo masculino y 18 del femenino. Se mantuvieron vivos al final del estudio cinco de los 20 pacientes que recibieron tratamiento quirúrgico, dos de los nueve tratados con cirugía más poliquimioterapia y uno de los tres tratados con radioterapia más cirugía. El 46 por ciento de los pacientes tuvo antecedentes de gastritis, el 22 por ciento de úlcera y el 60 por ciento historia familiar de tumores digestivos o no. Conclusiones: los pacientes afectados fueron fundamentalmente los ancianos del sexo masculino, con antecedentes personales de enfermedad gástrica, exposición a tóxicos y antecedentes familiares de enfermedad tumoral digestiva o extradigestiva. Tuvieron mejor pronóstico los que recibieron tratamiento quirúrgico solo o combinado


Objective: characterize patients with gastric cancer and describe their evolution with the treatment indicated. Methods: an observational descriptive study was conducted of 50 patients from the municipality of Caimito diagnosed with gastric cancer throughout 15 years. The variables studied were age; gender; personal history of gastric disease; family, occupational and nutritional history; antecedents of exposure to toxic substances, and evolution with the treatment indicated. Results: the largest number of patients diagnosed and deceased corresponds to the People's Councils of Caimito and Costa Norte. 32 patients were male and 18 female. The patients who remained alive at the end of the study period were five of the twenty who underwent surgical treatment, two of the nine who were treated with surgery plus polychemotherapy, and one of the three treated with radiotherapy plus surgery. 46 percent of the patients had a history of gastritis, 22 percent of ulcer and 60percent had family antecedents of tumors, either digestive or not. Conclusions: the patients affected were mainly male and elderly, with a history of gastric disease and exposure to toxic substances, and family antecedents of digestive or extradigestive tumoral disease. Patients who received surgical treatment, either alone or combined, had a better prognosis

ABSTRACT

Objetivo: O objetivo deste estudo foi revisar os resultados cirúrgicos e definir o perfil dos pacientes com câncer gástrico precoce (CGP) tratados em hospital universitário no Rio Grande do Sul. Método: Quarenta e quatro pacientes tratados por CGP foram estudados de forma retrospectiva. As principais variáveis em estudo foram: idade, gênero, sintomatologia, características anatomopatológicas do tumor, tratamento empregado, complicações do procedimento cirúrgico, mortalidade operatória e sobrevida aos cinco e 10 anos. Resultados: A incidência de CGP foi 8,38% dos pacientes ressecados por adenocarcinoma (44/525). Todos os pacientes foram submetidos à ressecção cirúrgica. A média de idade foi de 57,3 anos e o sexo masculino predominou com 61,4% dos casos. O sintoma mais comum foi dor ou desconforto epigástrico em 23 (52,3%) pacientes. A localização mais comum foi no terço distal do órgão em 24 (54,5%) casos. As apresentações macroscópicas mais comuns foram os tipos IIc e III. A linfadenectomia mais empregada foi a D1, em 30 (68,2%) pacientes. Quinze (34,1%) pacientes apresentaram tumor restrito à mucosa e em 29 (65,9%) a lesão invadia até a camada submucosa. Metástases linfonodais foram diagnosticadas em oito (18,2%) pacientes. Houve um (2,3%) óbito operatório e a sobrevida foi de 95,1% e 82,5% aos cinco e 10 anos, respectivamente. Conclusão: As excelentes taxas de cura dos pacientes com CGP obtidas pelos cirurgiões japoneses podem ser reproduzidas no Brasil, mesmo na presença de gânglios comprometidos, justificando esforços para aumento no diagnóstico precoce desta neoplasia em nosso meio (AU)


Objective: The aim of this study was to evaluate the results of the surgical treatment and the profile of patients diagnosed with early gastric cancer (EGC) in a tertiary care hospital in Southern Brazil. Methods: Forty-four patients who had operations for EGC were retrospectively evaluated. The main variables analyzed were: age, genre, clinical symptoms, site and stage of tumor, surgical procedure, surgical complications, operative mortality and long term survival. Results: The incidence of EGC was 8,38% of the resected patients (44/525). All patients were treated by surgical resection. The mean age at diagnosis was 57,3 years and there was a male predominance of 61,4%. Tenderness or epigastric pain was the most common clinical symptom. Tumors were typically located in the distal third of the stomach (54,5%). Macroscopically, the majority of the lesions were type IIc (45,4%) and III (25%). D1 lymphadenectomy was performed in 30 (68,2%) patients. Fifteen (34,1%) patients had intramucosal tumors and in 29 (65,9%) tumor extended into the submucosa. Eight (18,2%) patients had metastatic lymph nodes. Only 1 (2,86%) patient died of operative complications and the survival rate was 95,1% and 82,5% at five and 10 years respectively. Conclusion: The excellent results reported by Japanese surgeons in the treatment of EGC can be reproduced in Brazil, even in the presence of lymph nodes metastasis, and justify a strong support to increase this diagnosis in our country (AU)
