ABSTRACT

ABSTRACT BACKGROUND: As age advances, a higher burden of comorbidities and less functional reserve are expected, however, the impact of aging in the surgical outcomes of gastric cancer (GC) patients is unknown. OBJECTIVE: The aim of this study is to evaluate surgical outcomes of GC patients according to their age group. METHODS: Patients submitted to gastrectomy with curative intent due to gastric adenocarcinoma were divided in quartiles. Each group had 150 patients and age limits were: ≤54.8, 54.9-63.7, 63.8-72, >72. The outcomes assessed were: postoperative complications (POC), 90-day postoperative mortality, disease-free survival (DFS) and overall survival (OS). RESULTS: Major surgical complications were 2.7% in the younger quartile vs 12% for the others (P=0.007). Major clinical complications raised according to the age quartile: 0.7% vs 4.7% vs 5.3% vs 7.3% (P<0.042). ASA score and age were independent risk factors for major POC. The 90-day mortality progressively increased according to the age quartile: 1.3% vs 6.0% vs 7.3% vs 14% (P<0.001). DFS was equivalent among quartile groups, while OS was significantly worse for those >72-year-old. D2 lymphadenectomy only improved OS in the three younger quartiles. Age >72 was an independent risk factor for worse OS (hazard ratio of 1.72). CONCLUSION: Patients <55-year-old have less surgical complications. As age progresses, clinical complications and 90-day mortality gradually rise. OS is worse for those above age 72, and D2 lymphadenectomy should be individualized after this age.


RESUMO CONTEXTO: Conforme a idade avança, se esperam mais morbidades e menor reserva funcional. Entretanto não está claro qual o impacto do envelhecimento nos resultados cirúrgicos do câncer gástrico (CaG). OBJETIVO: O intuito deste estudo é avaliar os resultados cirúrgicos de pacientes com CaG de acordo com o grupo etário. MÉTODOS: Pacientes submetidos a gastrectomia por adenocarcinoma gástrico com intuito curativo foram divididos em quartis. Cada grupo incluiu 150 indivíduos e os limites etários foram: ≤54,8; 54,9-63,7; 63,8-72; >72. Os resultados avaliados foram: complicações pós-operatórias (CPO), mortalidade em 90 dias, sobrevida livre de doença (SLD) e sobrevida global (SG). RESULTADOS: Complicações cirúrgicas maiores ocorreram em 2,7% dos pacientes no quartil mais jovem vs 12% para os demais (P=0,007). A incidência de complicações clínicas maiores aumentou conforme o quartil: 0,7% vs 4,7% vs 5,3% vs 7,3% (P<0,042). A pontuação ASA e a idade foram fatores de risco independentes para CPO maiores. A mortalidade em 90 dias aumentou progressivamente conforme o quartil etário: 1,3% vs 6,0% vs 7,3% vs 14% (P<0,001). A SLD foi equivalente entre os quartis, enquanto a SG foi significativamente pior para os >72 anos de idade. Linfadenectomia D2 aumentou a SG apenas para os 3 quartis mais jovens. Idade > 72 foi fator independente de risco para pior SG (razão de chances de 1,72) CONCLUSÃO: Pacientes < 55 anos tem menos complicações cirúrgicas. Conforme a idade avança, as complicações clínicas e a mortalidade em 90 dias aumenta gradualmente. A SG é pior se >72 anos e a indicação de linfadenectomia D2 deve ser individualizada a partir dessa idade.

ABSTRACT

With the development of surgical treatment for gastric cancer, under the premise of ensuring the effect of surgical treatment, the objectives of preserving the function of stomach, diminishing the influence of quality of life and keeping the outcome of treatment, are the expectation of patients and the goal of surgeons. The emerge of function-preserving gastrectomy (FPG) indicates that the surgical treatment of gastric cancer steps into the individualized and precision era. Because the concept and operation procedures of FPG have not achieved consensus, the Gastrointestinal Surgery Branch, Surgery Branch, Chinese Medical Association (CMA) with Chinese Society of Surgical Oncology of Chinese Medical Doctor Association(CMDA), Chinese Society of Upper Gastrointestinal Surgeon of CMDA, Stomach and Intestines Committee of Chinese Anticancer Association, convenes some experts to summarize the recent literatures and discuss to reach the consensus about the FPG in the treatment of early gastric cancer. The definition of FPG is as follows: without compromising the oncological efficacy of early gastric cancer, decrease of the operational scale, selection of optimal reconstruction procedures and preservation of the gastric function as much as possible. The most common operation methods are procedures of minimized scale (pylorus-preserving gastrectomy, segmental gastrectomy, local gastrectomy and endoscopic resection) and proximal gastrectomy (PG). Besides the anastomosis of esophagus and gastric remnants, the reconstruction method after proximal gastrectomy also includes tubular gastroesophagostomy, double tract reconstruction, Interposition jejunostomy, side to side gastroesophagostomy (SOFY), double flap gastroesophagostomy (Kamikawa anastomosis), etc. The evaluation of gastric function after FPG includes the assessment of gastric remnant function, the functional complications and the nutritional status. We believe the publication of consensus will properly popularize FPG, promote further research about the gastric cancer and function of gastric remnant, and improve the theoretical study about FPG. Moreover, the indications and procedures of FPG will be broadened and renovated.

ABSTRACT

BACKGROUND@#The neoadjuvant chemotherapy is increasingly used in advanced gastric cancer, but the effects on safety and survival are still controversial. The objective of this meta-analysis was to compare the overall survival and short-term surgical outcomes between neoadjuvant chemotherapy followed by surgery (NACS) and surgery alone (SA) for locally advanced gastric cancer.@*METHODS@#Databases (PubMed, Embase, Web of Science, Cochrane Library, and Google Scholar) were explored for relative studies from January 2000 to January 2021. The quality of randomized controlled trials and cohort studies was evaluated using the modified Jadad scoring system and the Newcastle-Ottawa scale, respectively. The Review Manager software (version 5.3) was used to perform this meta-analysis. The overall survival was evaluated as the primary outcome, while perioperative indicators and post-operative complications were evaluated as the secondary outcomes.@*RESULTS@#Twenty studies, including 1420 NACS cases and 1942 SA cases, were enrolled. The results showed that there were no significant differences in overall survival (P = 0.240), harvested lymph nodes (P = 0.200), total complications (P = 0.080), and 30-day post-operative mortality (P = 0.490) between the NACS and SA groups. However, the NACS group was associated with a longer operation time (P < 0.0001), a higher R0 resection rate (P = 0.003), less reoperation (P = 0.030), and less anastomotic leakage (P = 0.007) compared with SA group.@*CONCLUSIONS@#Compared with SA, NACS was considered safe and feasible for improved R0 resection rate as well as decreased reoperation and anastomotic leakage. While unbenefited overall survival indicated a less important effect of NACS on long-term oncological outcomes.

ABSTRACT

In recent years, the treatment strategy of locally advanced gastric cancer (LAGC) has changed from surgery alone to multidisciplinary comprehensive treatment (MDT) based on surgery. Many evidences have shown that perioperative therapy can improve the survival of most patients with late-stage LAGC compared to surgery combined with postoperative adjuvant chemotherapy. However, there is still a lack of standards and guidelines for precise preoperative staging, indications of perioperative neoadjuvant and adjuvant therapy, and regimen selection. Based on relevant literature and clinical practice, Chinese Journal of Gastrointestinal Surgery combined with Gastric Cancer Association, China Anti-Cancer Association took the lead and organized multidisciplinary experts to discuss, and finally formulate this expert consensus. This consensus aims to improve surgeons' and physicians' cognition on the MDT of LAGC, especially for doctors in primary hospitals; to clarify the preoperative staging, the indication and regimen selection of perioperative neoadjuvant and adjuvant therapy; so as to improve the diagnosis and treatment level of gastric cancer and the prognosis of LAGC in China. The level of evidence and recommendation of this consensus is determined by the criteria of Grading of Recommendations, Assessment, Development and Evaluations (GRADE).

ABSTRACT

BACKGROUND@#With the wide application of endoscopic submucosal dissection (ESD) for early gastric neoplasms, metachronous gastric neoplasms (MGN) have gradually become a concern. This study aimed to analyze the characteristics of MGN and evaluate the treatment and follow-up outcomes of MGN patients.@*METHODS@#A total of 814 patients were retrospectively enrolled. All these patients were treated by ESD for early gastric cancer or gastric dysplasia between November 2006 and September 2019 at The First Medical Center of Chinese People's Liberation Army General Hospital. The risk factors for MGN were analyzed using Cox hazard proportional model. Moreover, the cumulative incidence, the correlation of initial lesions and MGN lesions, and the treatment and follow-up outcomes of MGN patients were analyzed.@*RESULTS@#A total of 4.5% (37/814) of patients had MGN after curative ESD. The 3-, 5-, and 7-year cumulative incidences of MGN were 3.5%, 5.1%, and 6.9%, respectively, and ultimately reaching a plateau of 11.3% at 99 months after ESD. There was no significant correlation between initial lesions and MGN lesions in terms of gross type (P = 0.178), location (long axis: P = 0.470; short axis: P = 0.125), and histological type (P = 0.832). Cox multivariable analysis found that initial multiplicity was the only independent risk factor of MGN (hazard ratio: 4.3, 95% confidence interval: 2.0-9.4, P < 0.001). Seventy-three percent of patients with MGN were treated by endoscopic resection. During follow-up, two patients with MGN died of gastric cancer with lymph node metastasis. The disease-specific survival rate was significantly lower in patients with MGN than that in patients without MGN (94.6% vs. 99.6%, P = 0.006).@*CONCLUSIONS@#The MGN rate gradually increased with follow-up time within 99 months after curative gastric ESD. Thus, regular and long-term surveillance endoscopy may be helpful, especially for patients with initial multiple neoplasms.

ABSTRACT

The robotic surgical system applied to gastrectomy is regarded as a safe technique which has similar short- and long-term outcomes compared to laparoscopic and open gastrectomy. With the iteration of anastomotic staplers and improvement of anastomotic skills, coupled with the flexible robot's rotatable device making the manual intracorporal anastomosis easier, gastrointestinal reconstruction after robotic gastrectomy has also started to move toward the era of complete intracorporal anastomosis. In order to further standardize the indications and operating points, the Upper Gastrointestinal Surgery Group of Surgical Branch of Chinese Medical Doctor Association, the Gastrointestinal Surgery Group of Surgery Branch of Chinese Medical Association, the Digestive Tract Cancer Committee of Chinese Research Hospital Association, and Cancer Gastroenterology Society of Chinese Anticancer Association jointly organized domestic experts in general surgery field to formulate the Chinese expert consensus on intracorporal digestive reconstruction after robotic gastrectomy (2021 edition). The definition of intracorporeal digestive reconstruction after robotic gastrectomy is that all surgical steps of digestive reconstruction are done totally in the abdominal cavity by robotic system or all steps mentioned above except jejunojejunal extracorporeal anastomosis. The digestive reconstructions mainly include Billroth I anastomosis, Billroth II anastomosis, Billroth II+ Braun anastomosis, Roux-en-Y anastomosis, Uncut Roux-en-Y anastomosis after distal gastrectomy; double-tract anastomosis, esophagogastric anastomosis by stapler or hand-sewn technique (double flap gastroesophagostomy) after proximal gastrectomy; FEEA method, π-type anastomosis, overlap method and modified procedures, Uncut Roux-en-Y anastomosis, Parisi's double-loop reconstruction after total gastrectomy. Compared with extracorporeal digestive reconstruction, intracorporeal digestive reconstruction operated by robotic system can minimize the surgical incision, reduce the risk of abdominal exposure and accelerate postoperative recovery, etc. Previous studies have demonstrated promising results. We believe that the publication of the consensus will guide surgeons to break through the technical barriers of intracorporeal digestive reconstruction after robotic gastrectomy, which will be more and more widespread with the gradual maturity of domestic robotic systems by bringing less medical costs.

ABSTRACT

RESUMO - RACIONAL: Apesar do avanço nas terapias, o prognóstico de pacientes com câncer gástrico (CG) avançado permanece ruim. Vários estudos demonstraram a expressão do receptor de estrogênio alfa (REa), porém seu significado no CG permanece controverso. OBJETIVO: relatar uma série de casos de CG com expressão de REa-positivo, e descrever suas características clínicopatológicas e prognóstico. MÉTODOS: Avaliamos retrospectivamente os pacientes com CG submetidos à gastrectomia com intenção curativa entre 2009 e 2019. A expressão do REa foi avaliada por imuno-histoquímica por meio da construção de microarranjos de tecido (TMA). Pacientes com adenocarcinoma gástrico ERa-negativos serviram como grupo comparação. RESULTADOS: No período selecionado, foram identificados 6 (1,8%) CG REa-positivos entre os 345 CG analisados. Todos os ERa-positivos eram homens, com idades entre 34-78 anos, tinham CG do tipo difuso de Lauren e pN+. Comparado aos REa-negativos, os CG REa-positivos associaram-se a maior diâmetro (p=0,031), gastrectomia total (p=0,012), tipo de Lauren difuso/misto (p=0,012), presença de invasão perineural (p=0,030) e metástase linfonodal (p=0,215). O estágio final foi o IIA em um caso; IIIA em três e IIIB em dois casos. Entre os 6 pacientes REa -positivos, 3 tiveram recorrência da doença (peritoneal) e morreram. Não houve diferença significativa na sobrevida entre os grupos REa-positivo e negativo. CONCLUSÃO: A expressão do REa é menos comum no CG, estando associada à histologia difusa e presença de metástases linfonodal, podendo servir como um marcador relacionado à progressão tumoral e pior prognóstico. Além disso, uma alta taxa de recorrência peritoneal foi observada em pacientes ERa-positivos.


ABSTRACT - BACKGROUND: Despite advances in therapies, the prognosis of patients with advanced gastric cancer (GC) remains poor. Several studies have demonstrated the expression of estrogen receptor alpha (ERa); however, its significance in GC remains controversial. AIM: The present study aims to report a case series of GC with ERa-positive expression and describe their clinicopathological characteristics and prognosis. METHODS: We retrospectively evaluated patients with GC who underwent gastrectomy with curative intent between 2009 and 2019. ERa expression was assessed by immunohistochemistry through tissue microarray construction. Patients with ERa-negative gastric adenocarcinoma served as a comparison group. RESULTS: During the selected period, 6 (1.8%) ERa-positive GC were identified among the 345 GC patients analyzed. All ERa-positive patients were men, aged 34-78 years, and had Lauren diffuse GC and pN+ status. Compared with ERa-negative patients, ERa-positive patients had larger tumor size (p=0.031), total gastrectomy (p=0.012), diffuse/mixed Lauren type (p=0.012), presence of perineural invasion (p=0.030), and lymph node metastasis (p=0.215). The final stage was IIA in one case, IIIA in three cases, and IIIB in two cases. Among the six ERa-positive patients, three had disease recurrence (peritoneal) and died. There was no significant difference in survival between ERa-positive and ERa-negative groups. CONCLUSIONS: ERa expression is less common in GC, is associated with diffuse histology and presence of lymph node metastasis, and may be a marker related to tumor progression and worse prognosis. Also, a high rate of peritoneal recurrence was observed in ERa-positive patients.

ABSTRACT

RESUMO - RACIONAL: A cirurgia de resgate é definida como a ressecção cirúrgica após falha de primeiro tratamento com intuito curativo. OBJETIVO: Relatar a experiência de um centro de referência no tratamento do câncer gástrico com a cirurgia de resgate para o adenocarcinoma de estômago. MÉTODOS: Análise retrospectiva dos pacientes com câncer gástrico operados entre 2009 e 2020. RESULTADOS: 40 pacientes foram submetidos à tentativa de gastrectomia de resgate com intuito curativo. Para análise, foram divididos em dois grupos: 23 pacientes após ressecção endoscópica e 17 após gastrectomia. No primeiro grupo, todos tiveram ressecção com margens livres, a média de internação foi 15,7 dias e 2 (8,6%) tiveram complicações maiores. No seguimento médio de 37,2 meses, houve apenas 1 recidiva. A sobrevida global média foi 46 meses. No grupo pós-gastrectomia 9 (52,9%) foram resgatados com intenção curativa, a média de internação foi 12,2 dias e 3 (17,6%) apresentaram complicações maiores. No seguimento médio de 22 meses, 5 recidivaram. A sobrevida global média e a sobrevida livre de doença foram respectivamente: 24 e 16,5 meses. CONCLUSÃO: A cirurgia de resgate no câncer gástrico oferece nova possibilidade de controle da doença a longo prazo e/ou aumento de sobrevida, tendo taxa de complicações aceitáveis.


ABSTRACT - BACKGROUND: Salvage surgery (SS) is defined as surgical resection after the failure of the first treatment with curative intent. AIM: The aim of this study was to report the experience of a reference center with SS for stomach adenocarcinoma. METHODS: This is a retrospective study of patients with gastric cancer (GC) operated on between 2009 and 2020. RESULTS: Notably, 40 patients were recommended for salvage gastrectomy with curative-intent treatment. For analysis purpose, patients were divided into two groups: 23 patients after endoscopic resection and 17 patients after gastrectomy. In the first group, all patients underwent R0 resection, their average hospital length of stay (LOS) was 15.7 days, and 2 (8.6%) patients had major complications. During the average follow-up of 37.2 months, there was only one recurrence. The median overall survival (OS) was 46 months. In the postgastrectomy group, 9 (52.9%) patients were rescued with curative intent, the average hospital LOS was 12.2 days, and 3 (17.6%) had major complications. In a mean follow-up of 22 months, five patients relapsed. Median OS and disease-free survival were 24 and 16.5 months, respectively. CONCLUSION: SS in GC offers the possibility of long-term disease control and increased survival rate with an acceptable complication rate.

ABSTRACT

ABSTRACT Background: Due to the longer life expectancy and consequently an increase in the elderly population, a higher incidence of gastric cancer is expected in this population in the coming decades. Aim: To compare the results of laparoscopic GC surgical treatment between individuals aged<65 years (group I) and ≥ 65 years (group II), according to clinical, surgical, and histopathological characteristics. Methods: A observational retrospective study was performed by analyzing medical charts of patients with gastric cancer undergoing total or subtotal laparoscopic gastrectomy for curative purposes by a single oncologic surgery team. Results: Thirty-six patients were included in each group. Regarding the ASA classification, 31% of the patients in group I was ASA 1, compared to 3.1% in group II. The mean number of concomitant medications in group II was statistically superior to group I (5±4.21 x 1.42±3.08, p<0.001). Subtotal gastrectomy was the most performed procedure in both groups (69.4% and 63.9% in groups I and II, respectively) due to the high prevalence of distal tumors in both groups, 54.4% group I and 52.9% group II. According to Lauren's classification, group I presented a predominance of diffuse tumors (50%) and group II the intestinal type (61.8%). There was no difference between the two groups regarding the number of resected lymph nodes and lymph node metastases and the days of hospitalization and mortality. Conclusion: Laparoscopic gastrectomy showed to be a safe procedure, without a statistical difference in morbidity, mortality, and hospitalization time between both groups.


RESUMO Racional: Devido à maior expectativa de vida, e consequentemente aumento da população de idosos, é esperada uma maior incidência de câncer gástrico nesta população nas próximas décadas. Objetivos: Comparar os resultados do tratamento cirúrgico por via laparoscópica do câncer gástrico entre pacientes com idade <65 anos (grupo I) e ≥65 anos (grupo II), de acordo com características clínicas, cirúrgicas e histopatológicas. Métodos: Foi realizado um estudo retrospectivo, observacional baseado na análise de prontuários médicos de pacientes com câncer gástrico, submetidos à gastrectomia total ou subtotal laparoscópica com finalidade curativa, por uma única equipe de cirurgia oncológica. Resultados: Foram avaliados 36 pacientes em cada grupo. Em relação à classificação ASA, 62,1% dos pacientes do grupo I eram ASA 1 comparado a 3.1% no grupo II. O número médio de medicações concomitantes do grupo II foi superior ao grupo I (5±4,21 x 1.42±3,08, p<0.001). A gastrectomia subtotal foi o procedimento mais realizado nos dois grupos (69,4% e 63,9% nos grupos I e II respectivamente) devido a maior prevalência de tumores distais em ambos os grupos, 54.4% grupo I e 52.9% grupo II. De acordo com a classificação de Laurén, no grupo I houve predomínio de tumores difusos (50,0%) e no grupo II do tipo intestinal (61,8%). Não houve diferença entre os dois grupos em relação a quantidade de linfonodos ressecados e de linfonodos positivos para metástases, assim como o tempo de permanência no CTI, dias de hospitalização e mortalidade. Conclusão: A gastrectomia por via laparoscópica é procedimento seguro, sem haver diferenças em morbidade, mortalidade e tempo de internação entre pacientes jovens e idosos.

ABSTRACT

ABSTRACT Background: Gastric and esophagogastric junction adenocarcinoma are responsible for approximately 13.5% of cancer-related deaths. Given the fact that these tumors are not typically detected until they are already in the advanced stages, neoadjuvancy plays a fundamental role in improving long-term survival. Identification of those with complete pathological response (pCR) after neoadjuvant chemotherapy (NAC) is a major challenge, with effects on organ preservation, extent of resection, and additional surgery. There is little or no information in the literature about which endoscopic signs should be evaluated after NAC, or even when such re-evaluation should occur. Aim: To describe the endoscopic aspects of patients with gastric and esophagogastric junction adenocarcinomas who underwent NAC and achieved pCR, and to determine the accuracy of esophagogastroduodenoscopy (EGD) in predicting the pCR. Methods: A survey was conducted of the medical records of patients with these tumors who were submitted to gastrectomy after NAC, with anatomopathological result of pCR. Results: Twenty-nine patients were identified who achieved pCR after NAC within the study period. Endoscopic responses were used to classify patients into two groups: G1-endoscopic findings consistent with pCR and G2-endoscopic findings not consistent with pCR. Endoscopic evaluation in G1 was present in an equal percentage (47.4%; p=0.28) in Borrmann classification II and III. In this group, the predominance was in the gastric body (57.9%; p=0.14), intestinal subtype with 42.1% (p=0.75), undifferentiated degree, 62.5% (p=0.78), Herb+ in 73.3% (p=0.68). The most significant finding, however, was that the time interval between NAC and EGD was longer for G1 than G2 (24.4 vs. 10.2 days, p=0.008). Conclusion: EGD after NAC seems to be a useful tool for predicting pCR, and it may be possible to use it to create a reliable response classification. In addition, the time interval between NAC and EGD appears to significantly influence the predictive power of endoscopy for pCR.


RESUMO Racional: O adenocarcinoma gástrico e da junção esofagogástrica é responsável por aproximadamente 13,5% das mortes relacionadas ao câncer. Dado que esses tumores não são normalmente detectados até que já estejam em estágios avançados, a neoadjuvância desempenha um papel fundamental na melhoria da sobrevida em longo prazo. A identificação daqueles com resposta patológica completa (pCR) após a quimioterapia neoadjuvante (NAC) é um grande desafio, com efeitos na preservação do órgão, extensão da ressecção e cirurgia adicional. Há pouca ou nenhuma informação na literatura sobre quais sinais endoscópicos devem ser avaliados após a NAC, ou mesmo quando essa reavaliação deve ocorrer. Objetivo: Descrever os aspectos endoscópicos de pacientes com adenocarcinoma gástrico e da junção esofagogástrica que foram submetidos à quimioterapia neoadjuvante e alcançaram pCR, e determinar a acurácia da esofagogastroduodenoscopia (EGD) em predizer a pCR. Métodos: Foram revisados os prontuários de pacientes submetidos à gastrectomia subtotal e total após NAC, com resultado anatomopatológico de pCR. Resultados: Vinte e nove pacientes que alcançaram pCR após NAC foram identificados no período estudado. As respostas endoscópicas foram usadas para classificar os pacientes em dois grupos: G1- achados endoscópicos consistentes com pCR, G2 - achados endoscópicos não consistentes com pCR. A avaliação endoscópica no G1 esteve presente em igual percentual (47,4%; p=0,28) na classificação de Borrmann II e III. Nesse grupo, a predominância foi no corpo gástrico (57,9%; p=0,14), subtipo intestinal com 42,1% (p=0,75), grau indiferenciado, 62,5% (p=0,78), Herb+ em 73,3% (p=0,68). O achado mais significativo, no entanto, foi que o intervalo de tempo entre NAC e EGD foi maior para G1 do que G2 (24,4 vs. 10,2 dias, p=0,008). Conclusão: A EGD após NAC, nessa pesquisa, sugeriu ser método útil para prever pCR, mediante uma classificação de resposta confiável. Além disso, o intervalo de tempo entre NAC e EGD parece influenciar significativamente a sua capacidade preditiva de diagnosticar a pCR.

ABSTRACT

ABSTRACT Background : The II Brazilian Consensus on Gastric Cancer of the Brazilian Gastric Cancer Association BGCA (Part 1) was recently published. On this occasion, countless specialists working in the treatment of this disease expressed their opinion in the face of the statements presented. Aim : To present the BGCA Guidelines (Part 2) regarding indications for surgical treatment, operative techniques, extension of resection and multimodal treatment. Methods: To formulate these guidelines, the authors carried out an extensive and current review regarding each declaration present in the II Consensus, using the Medline/PubMed, Cochrane Library and SciELO databases initially with the following descriptors: gastric cancer, gastrectomy, lymphadenectomy, multimodal treatment. In addition, each statement was classified according to the level of evidence and degree of recommendation.

ABSTRACT

ABSTRACT Background: Nearly 10% of node negative gastric cancer patients who underwent curative surgery have disease recurrence. Western data is extremely poor on this matter and identifying the risk factors that associate with relapse may allow new strategies to improve survival. Aim: Verify the clinical and pathological characteristics that correlate with recurrence in node negative gastric cancer. Methods: All gastric cancer patients submitted to gastrectomy between 2009 and 2019 at our institution and pathologically classified as N0 were considered. Their data were available in a prospective database. Inclusion criteria were: gastric adenocarcinoma, node negative, gastrectomy with curative intent, R0 resection. Main outcomes studied were: disease-free survival and overall survival. Results: A total of 270 patients fulfilled the inclusion criteria. Mean age was 63-year-old and 155 were males. Subtotal gastrectomy and D2 lymphadenectomy were performed in 64% and 74.4%, respectively. Mean lymph node yield was 37.6. Early GC was present in 54.1% of the cases. Mean follow-up was 40.8 months and 19 (7%) patients relapsed. Disease-free survival and overall survival were 90.9% and 74.6%, respectively. Independent risk factors for worse disease-free survival were: total gastrectomy, lesion size ≥3.4 cm, higher pT status and <16 lymph nodes resected. Conclusion: In western gastric cancer pN0 patients submitted to gastrectomy, lymph node count <16, pT3-4 status, tumor size ≥3.4 cm, total gastrectomy and presence of lymphatic invasion, are all risk factors for disease relapse.


RESUMO Racional: Aproximadamente 10% dos pacientes com câncer gástrico submetidos a operação curativa e sem linfonodos acometidos irão apresentam recorrência da doença. Os dados ocidentais são extremamente pobres sobre este assunto e a identificação dos fatores de risco associados à recidiva podem permitir novas estratégias para melhorar a sobrevida. Objetivo: Identificar as características clínicas e patológicas que se correlacionam com recidiva em pacientes com câncer gástrico pN0. Métodos: Foram considerados todos os pacientes com câncer gástrico submetidos à gastrectomia entre 2009 e 2019 em nossa instituição e que na classificação patológica não apresentaram acometimento linfonodal. Os critérios de inclusão foram: adenocarcinoma gástrico, pN0, gastrectomia com intenção curativa, ressecção R0. Os principais desfechos estudados foram: sobrevida livre de doença e sobrevida global. Resultados: Ao todo 270 pacientes preencheram os critérios de inclusão. A idade média foi de 63 anos e 155 eram homens. A gastrectomia subtotal e a linfadenectomia D2 foram realizadas em 64% e 74,4%, respectivamente. A média de linfonodos ressecados foi de 37,6. Câncer gástrico precoce estava presente em 54,1% dos casos. O seguimento médio foi de 40,8 meses e 19 (7%) apresentaram recidiva. A sobrevida livre de doença e sobrevida global foram de 90,9% e 74,6%, respectivamente. Os fatores de risco independentes para pior sobrevida livre de doença foram: gastrectomia total, lesão ≥3,4 cm, status pT avançado e <16 linfonodos ressecados. Conclusão: Os fatores de risco para recidiva no grupo estudado foram: <16 linfonodos ressecados, status pT3-4, tumor ≥3,4 cm, gastrectomia total e presença de invasão linfática.

ABSTRACT

ABSTRACT BACKGROUND: During a surgical procedure, patients are often subjected to fasting for times that are more prolonged than the ideal, which may lead to complications. OBJECTIVE: To evaluate the duration of perioperative fasting and its association with postoperative complications, length of hospital stay (LOS) and mortality among gastric and colorectal cancer patients. DESIGN AND SETTING: Cohort study developed in a surgical oncology hospital in the city of Natal (Rio Grande do Norte, Brazil). METHODS: Patients aged over 18 years were included. The Clavien-Dindo surgical complication scale was used to evaluate occurrences of postoperative complications. LOS was defined as the number of days for which patients stayed in the hospital after surgery, or until the day of death. RESULTS: Seventy-seven patients participated (59.8 ± 11.8 years; 54.5% females; 70.1% with bowel tumor). The incidences of postoperative complications and death were 59.7% and 3.9%, respectively. The duration of perioperative fasting was 59.0 ± 21.4 hours, and it was higher among non-survivors and among patients with prolonged hospital stay (≥ 6 days). For each one-hour increase in the durations of perioperative and postoperative fasting, the odds of prolonged hospitalization increased by 12% (odds ratio, OR = 1.12; 95% confidence interval, CI 1.04-1.20) and 5% (OR = 1.05; 95% CI 1.02-1.08), respectively. CONCLUSION: Prolonged perioperative fasting, especially in the postoperative period, was observed in a sample of patients with gastric and colorectal cancer, and this was an independent predictor of LOS.

ABSTRACT

Resumen Introducción: El cáncer gástrico es un problema de salud en Chile y su mal pronóstico global se explica por un diagnóstico en etapas avanzadas. El cáncer gástrico incipiente (CGI) se asocia a buen pronóstico oncológico y la disección submucosa endoscópica (DSE) como alternativa de tratamiento ha demostrado ser comparable al estándar quirúrgico. Objetivo: Describir la experiencia y resultados de un cirujano en pacientes con CGI sometidos a DSE. Materiales y Método: Estudio retrospectivo que incluyó a los pacientes sometidos a DSE por CGI entre mayo de 2015 y marzo de 2019. Se tabuló información demográfica, datos perioperatorios y del seguimiento obtenidos del registro institucional. Se utilizó estadística descriptiva. Resultados: Se realizaron 52 DSE por CGI en el período analizado. La resección en bloque se logró en un 96% de los casos. La morbilidad alcanzó el 2%, no se registró mortalidad postoperatoria. 98% de las resecciones en bloque fueron consideradas R0 y un 86% de ellas cumplieron estándares de curación. La mediana de seguimiento es de 19 meses y la sobrevida específica por cáncer gástrico y libre de recurrencia alcanza el 100%. Discusión: La DSE es una técnica con potencial curativo en pacientes con CGI, presentando mejores resultados en términos de morbimortalidad, calidad de vida y es comparable a la cirugía en el pronóstico oncológico. Los resultados presentados son concordantes con la literatura y apoyan la implementación de la técnica para el tratamiento del CGI.


Introduction: Gastric cancer is a serious health problem in Chile and its poor prognosis is explained by usual diagnosis in advanced stages. Early gastric cancer (EGC) is associated with good oncological prognosis and endoscopic submucosal dissection (ESD) as its treatment has shown to be comparable to the surgical standard. Aim: Describe the experience and results of a surgeon in patients with EGC undergoing ESD. Materials and Method: Retrospective study including patients undergoing ESD for EGC between May 2015 and March 2019. Demographic information, perioperative and follow-up data obtained from the institutional registry were tabulated. Descriptive statistics was used. Results: 52 ESD were performed per EGC in the analyzed period. En bloc resection was achieved in 96% of cases. Morbidity reached 2% and no postoperative mortality was recorded. 98% of the en bloc resections were considered R0 and 86% of them met healing standards. The median follow-up is 19 months and the specific survival due to gastric cancer and recurrence-free rates reach 100%. Discussion: ESD is a technique with curative potential in patients with EGC, presenting better results in terms of morbidity and mortality, quality of life and is comparable to surgery in the oncological prognosis. The results presented are consistent with the literature and support the implementation of the technique for the treatment of EGC.

ABSTRACT

SUMMARY: Gastric cancer (CG) is the second leading cause of cancer deaths. The best treatment option for patients with advanced GC (AGC) is still surgery, which involves performing a gastrectomy and D2 lymphadenectomy (D2L). The aim of this study was to determine postoperative morbidity (POM) and 5-year OS in patients resected by AGC without neoadjuvant. Case series with follow-up of patients with AGC undergoing total or subtotal gastrectomies and D2L, consecutively at RedSalud Mayor Temuco Clinic, between 2008 and 2019. The outcome variables were POM and 5-year OS. Other variables of interest were surgical time, number of resected lymph nodes, hospital stay, and recurrence. Descriptive statistics was used, and Kaplan-Meier curves were calculated. In this analysis 38 patients (71.1 % men), with a median age of 65 years, were operated. The most frequent location was subcardial (50.0 %). The most frequent type of resection was total gastrectomy (60.5 %). The median of surgical time, number of resected lymph nodes and hospital stay; was 190 min, 32 and 6 days respectively. MPO was 18.4 %. With a median follow-up of 28 months, a recurrence of 44.7 % was verified; and 5-year OS for stages IIIA, IIIB and IV were 53.3 %, 46.1 % and 20.0 % respectively (p= 0,007). The results achieved, in terms of POM and OS series were similar to national and international series in which neoadjuvant therapies have not been applied.


RESUMEN: El cáncer gástrico (CG) es la segunda causa de muerte por cáncer. La mejor opción terapéutica para pacientes con CG avanzado (CGA), sigue siendo la cirugía, que supone la realización de gastrectomía asociada a linfadenectomía D2 (LD2). El objetivo de este estudio fue determinar morbilidad postoperatoria (MPO) y supervivencia (SV) en pacientes resecados por CGA sin neoadyuvancia. Serie de casos con seguimiento, de pacientes con CGA sometidos a gastrectomía total o subtotal con LD2, de forma consecutiva, en Clínica RedSalud Mayor Temuco, entre 2008 y 2019. Las variables resultado fueron MPO y SV actuarial global (SVAG) a 5 años. Otras variables de interés fueron: tiempo quirúrgico, número de linfonodos resecados, estancia hospitalaria y recurrencia. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión; y análisis de SV con curvas de Kaplan Meier. Se intervinieron 38 pacientes (71,1 % hombres), con una mediana de edad de 65 años. La localización más frecuente fue subcardial (50,0 %); el tipo de resección más frecuente fue gastrectomía total (60,5 %). Las medianas del tiempo quirúrgico, del número de linfonodos resecados y de estancia hospitalaria; fue 190 min, 32 y 6 días respectivamente. La MPO fue 18,4 %. Con una mediana de seguimiento de 28 meses, se verificó recurrencia de 44,7 %; y SVAG a 5 años para estadios IIIA, IIIB y IV de 53,3%, 46,1 % y 20,0 % respectivamente (p=0,007). Los resultados obtenidos, en términos de MPO, mortalidad y SVAG, fueron similares a series de centros de derivación nacionales e internacionales en los que no se ha aplicado terapias neoadyuvantes.

ABSTRACT

Resumen El cáncer gástrico es una patología de alta incidencia en Chile. Afortunadamente es baja la incidencia de márgenes R1 cuando se realiza una cirugía con intención curativa. Al tener un tumor subcardial o cardial es perentorio realizar una biopsia rápida (intraoperatoria), en caso que ésta resulte positiva, es difícil tomar una decisión sobre qué realizar a continuación, ya que el realizar una esofagoyeyunoanastomosis intratorácica aumenta el riesgo quirúrgico. Para esto, es de suma importancia tener la información de las características histopatológicas del tumor, el riesgo de filtración, la recurrencia, la sobrevida, las terapias adyuvantes y la realidad país. Se realizó una revisión de la literatura con el fin de poder guiar la toma de decisiones.


Gastric cancer is a pathology with a high incidence in Chile, fortunately, the incidence of R1 margins is low when performing surgery with curative intent. When having a sub cardial or cardial tumor, it is essential to perform a rapid (intraoperative) biopsy, if this is positive when cutting the esophagus just under the pillars, it is difficult to make the decision of what to do next, since performing an inthrathoracic esophagojejunostomy increases the surgical risk. For this, it is very important to have information about the histopathological characteristics of the tumor, the leakage risk, there currence, the survival, the adjuvant therapies and the reality of the country. A review of the literature was done in order to guide the decisions.

ABSTRACT

BACKGROUND@#Despite the recent large number of studies comparing endoscopic and laparoscopic resection for small gastrointestinal stromal tumors (GISTs) (diameter ≤ 5 cm), the results remain conflicting. The objective of this work was to perform a cumulative meta-analysis to assess the advantages and disadvantages of endoscopic resection vs. laparoscopic resection.@*METHODS@#The meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We searched medical databases up to January 2020. Meta-analytical random or fixed effects models were used in pooled analyses. Meta-regression, cumulative meta-analyses, and subgroup analyses were performed to improve the accuracy of the conclusion. Sensitivity analyses were applied to assess the robustness of the results.@*RESULTS@#A total of 12 cohort studies with 1383 participants comparing endoscopic resection and laparoscopic resection were identified, while three cohort studies with 167 participants comparing endoscopic resection and laparoscopic and endoscopic cooperative surgery were found. We found that endoscopic resection had shorter operation times (weighted mean difference [WMD] = -27.1 min, 95% confidence interval [CI]: -40.8 min to -13.4 min) and lengths of hospital stay (WMD = -1.43 d, 95% CI: -2.31 d to -0.56 d) than did laparoscopic resection. The results were stable and reliable. There were no significant differences in terms of blood loss, hospitalization costs, incidence of complications or recurrence rates. For tumor sizes 2 - 5 cm, endoscopic resection increased the risk of positive margins (relative risk [RR] = 5.78, 95% CI: 1.31 - 25.46). Although operation times for endoscopic resection were shorter than those of laparoscopic and endoscopic cooperative surgery (WMD = -41.03 min, 95% CI: -59.53 min to -22.54 min), there was a higher incidence of complications (RR = 4.03, 95% CI: 1.57 - 10.34).@*CONCLUSIONS@#In general, endoscopic resection is an alternative method for gastric GISTs ≤ 5 cm. Laparoscopic and endoscopic cooperative surgery may work well in combination. Further randomized controlled trials are recommended to validate or update these results.

ABSTRACT

ABSTRACT Background: remnant gastric cancer (RGC) develops five years or later after previous resection for benign or malignant lesion. The treatment is performed through completion total gastrectomy (CTG) with radical lymphadenectomy. Some reports consider this procedure may be associated with higher rates of morbidity and mortality. Objective: to evaluate surgical results and survival after CTG in patients with RGC. Methods: 54 patients who underwent CTG between 2009 and 2019 were included in the study. As a comparison group 215 patients with primary gastric cancer (PGC) who underwent total gastrectomy (TG) in the same period were selected. Results: among the initial characteristics, age (68.0 vs. 60.5; p<0.001), hemoglobin values (10.9 vs. 12.3; p<0.001) and body mass index (22.5 vs. 24.6; p=0.005) were different between the RGC and PGC groups, respectively. The most frequent postoperative complications were related to pulmonary complications, infection and fistula in both groups. There was a higher incidence of esophagojejunal fistula in the CTG group (14.8% vs 6.5%, p=0.055). Perioperative mortality was higher in RGC patients (9.3% vs. 5.1%), but without significance (p=0.329). Hospital length of stay, postoperative complications graded by the Clavien-Dindo classification, mortality at 30 and 90 days were not different between groups. There was no significant difference in disease-free and overall survival between RGC and PGC groups. Conclusion: despite previous reports, surgical results and survival were similar between groups. Higher risk of esophagojejunal fistula must be considered.


RESUMO Antecedentes: o câncer do coto ou remanescente gástrico (CRG) se desenvolve cinco anos ou mais após a ressecção gástrica por lesão benigna ou maligna. O tratamento é realizado através da gastrectomia total complementar (GTC) com linfadenectomia. Alguns relatos consideram que esse procedimento pode estar associado a maiores taxas de morbimortalidade. Objetivo: avaliar os resultados cirúrgicos e a sobrevida após GTC em pacientes com CRG. Métodos: 54 pacientes submetidos a GTC entre 2009 e 2019 foram incluídos no estudo. Como grupo de comparação, foram selecionados 215 pacientes com câncer gástrico primário (CGP) submetidos à gastrectomia total (GT) no mesmo período. Resultados: dentre as características iniciais, a idade média (68,0 vs. 60,5; p <0,001), os valores de hemoglobina (10,9 vs. 12,3; p <0,001) e o índice de massa corporal (22,5 vs. 24,6; p = 0,005) diferiram entre os grupos CRG e CGP, respectivamente. As complicações pós-operatórias mais frequentes foram pulmonares, infecciosas e fístulas nos dois grupos. Houve maior incidência de fístula esofagojejunal no grupo GTC (14,8% vs 6,5%, p = 0,055). A mortalidade perioperatória foi maior nos pacientes com CRG (9,3% vs. 5,1%), mas sem significância (p = 0,329). O tempo de internação hospitalar, complicações pós-operatórias (Clavien-Dindo), mortalidade aos 30 e 90 dias não foram diferentes entre os grupos. Não houve diferença significativa na sobrevida livre de doença e global entre os grupos CRG e CGP. Conclusão: apesar dos relatos anteriores, os resultados cirúrgicos e a sobrevida foram semelhantes entre os grupos. Maior risco de fístula esofagojejunal dever ser considerado.

ABSTRACT

ABSTRACT Percutaneous endoscopic gastrostomy is used to provide enteral nutritional support for patients with obstructive oropharyngeal or esophageal neoplasms. The placement of the catheter is considered safe, with few complications. Despite this, a specific complication that is considered rare, has been increasingly described in the literature, i.e., metastasis of head and neck cancer in the gastrostomy stoma. In this report, we described a case of metastasis of squamous cell carcinoma of the larynx in the gastrostomy site, and discussed the possible etiologies and alternatives, seeking to reduce the incidence of this complication.


RESUMO A gastrostomia endoscópica percutânea é utilizada para oferecer suporte nutricional enteral para pacientes com neoplasias obstrutivas de orofaringe ou esôfago. A colocação da sonda é considerada segura, com poucas complicações. Apesar disso, uma complicação em particular, considerada rara, está sendo cada vez mais descrita na literatura: a metástase de neoplasia de cabeça e pescoço para o estoma da gastrostomia. Neste relato, descrevemos um caso de metástase de carcinoma espinocelular de laringe para o sítio da gastrostomia, e discutimos as possíveis etiologias e alternativas, buscando diminuir a incidência desta complicação.
