Cancer risk-reducing surgery: Brazilian society of surgical oncology guideline part 1 (gynecology and breast).

BACKGROUND: Risk-reducing operations are an important part of the management of hereditary predisposition to cancer. In selected cases, they can considerably reduce the morbidity and mortality associated with cancer in this population. OBJECTIVES: The Brazilian Society of Surgical Oncology (BSSO) developed this guideline to establish national benchmarks for cancer risk-reducing operations. METHODS: The guideline was prepared from May to December 2021 by a multidisciplinary team of experts to discuss the surgical management of cancer predisposition syndromes. Fourteen questions were defined and assigned to expert groups that reviewed the literature and drafted preliminary recommendations. Following a review by the coordinators and a second review by all participants, the groups made final adjustments, classified the level of evidence, and voted on the recommendations. RESULTS: For all questions including risk-reduction bilateral salpingo-oophorectomy, hysterectomy, and mastectomy, major agreement was achieved by the participants, always using accessible alternatives. CONCLUSION: This and its accompanying article represent the first guideline in cancer risk reduction surgery developed by the BSSO, and it should serve as an important reference for the management of families with cancer predisposition.

Brazilian Society of Surgical Oncology consensus on fertility-sparing surgery for cervical cancer.

OBJECTIVE: Several controversies remain on conservative management of cervical cancer. Our aim was to develop a consensus recommendation on important and novel topics of fertility-sparing treatment of cervical cancer. METHODS: The consensus was sponsored by the Brazilian Society of Surgical Oncology (BSSO) from March 2020 to September 2020 and included a multidisciplinary team of 55 specialists. A total of 21 questions were addressed and they were assigned to specialists' groups that reviewed the literature and drafted preliminary recommendations. Further, the coordinators evaluated the recommendations that were classified by the level of evidence, and finally, they were voted by all participants. RESULTS: The questions included controversial topics on tumor assessment, surgical treatment, and surveillance in conservative management of cervical cancer. The two topics with lower agreement rates were the role of minimally invasive approach in radical trachelectomy and parametrial preservation. Additionally, only three recommendations had <90% of agreement (fertility preservation in Stage Ib2, anti-stenosis device, and uterine transposition). CONCLUSIONS: As very few clinical trials have been developed in surgery for cervical cancer, most recommendations were supported by low levels of evidence. We addressed important and novel topics in conservative management of cervical cancer and our study may contribute to literature.

Surgical cancer care in the COVID-19 era: front line views and consensus.

OBJECTIVE: to suggest a script for surgical oncology assistance in COVID-19 pandemic in Brazil. METHOD: a narrative review and a "brainstorming" consensus were carried out after discussion with more than 350 Brazilian specialists and renowned surgeons from Portugal, France, Italy and United States of America. RESULTS: consensus on testing for COVID-19: 1- All patients to be operated should be tested between 24 and 48 before the procedure; 2- The team that has contact with sick or symptomatic patients should be tested; 3 - Chest tomography was suggested to investigate pulmonary changes. Consensus on protection of care teams: 1 - Use of surgical masks inside the hospitals. Use of N95 masks for all professionals in the operating room; 2 - Selection of cases for minimally invasive surgery and maximum pneumoperitoneal aspiration before removal of the surgical specimen; 2 - Optimization of the number of people in teams, with a minimum number of professionals, reducing their occupational exposure, the consumption of protective equipment and the circulation of people in the hospital environment; 3 - Isolation of contaminated patients. Priority consensus: 1- Construction of service priorities; 2 - Interdisciplinary discussion on minimally invasive or conventional pathways. CONCLUSION: the Brazilian Society of Surgical Oncology (BSSO) suggests a script for coping with oncological treatment, remembering that the impoundment in the assistance of these cases, can configure a new wave of overload in health systems.

Analysis of the surgical management of patients with recurrent cervical cancer after radiotherapy and chemotherapy. / Análise do manejo cirúrgico de pacientes com câncer cervical recidivado após radioterapia e quimioterapia.

OBJECTIVE: To analyze the results of morbidity and survival after curative and palliative surgery in recurrent cervical cancer patients who underwent chemoradiation as their primary treatment. Another goal was to assess the factors associated with curative and non-curative procedures. METHODS: This was a retrospective cohort consisting of patients undergoing surgery curative and palliative from January 2011 to December 2017 at a high complexity oncology center. Outcome of morbidity was reported according to the Clavien-Dindo classification, and survival analysis was carried out using the Kaplan-Meir method. To assess the factors associated with the procedures, a univariate analysis using the Mann-Whitney U test was performed. RESULTS: Two radical hysterectomies, three pelvic exenterations with curative intent, and five palliatives pelvic exenterations were performed. In the curative group, there were major complications in 40% of the cases, and the median survival time was 16 months. In the palliative group, there were major complications in 60% of the cases, and the median survival time was 5 months. Advanced staging (p-value= 0.02), symptoms (p-value=0.04), tumor size greater than five centimeters (p-value=0.04), and more than three organs involved (p-value=0.003) were factors significantly associated with non-curative surgery. CONCLUSIONS: The morbidity rates of this study were higher in palliative group, and the median survival time was lower in the palliative group than the curative group, but this difference in survival was not statistically significant. Advanced stage, symptoms, tumor size and number of organs involved are factors that should be taken into consideration when indicating surgical salvage.

OBJETIVOS: Analisar os resultados de morbidade e sobrevida após cirurgias curativas e paliativas em pacientes com câncer cervical recidivado após tratamento primário com radioterapia e quimioterapia. Outro objetivo foi avaliar os fatores associados aos procedimentos curativos e não curativos. MÉTODOS: Coorte retrospectiva de pacientes submetidos à cirurgias curativas e paliativas, entre janeiro de 2011 a dezembro de 2017, em um centro de alta complexidade em oncolologia. O desfecho da morbidade foi relatado de acordo com a classificação de Clavien-Dindo e a análise de sobrevida foi realizada pelo método de Kaplan-Meir. Para avaliar os fatores associados aos procedimentos, foi realizada análise univariada pelo teste U de Mann-Whitney. RESULTADOS: Foram realizadas duas histerectomias radicais, três exenterações pélvicas com intenção curativa e cinco exenterações pélvicas paliativas. No grupo curativo, houve complicações maiores em 40% dos casos, e o tempo mediano de sobrevida foi 16 meses. No grupo paliativo, houve complicações maiores em 60% dos casos, e o tempo mediano de sobrevida foi 5 meses. Estadiamento avançado (p=0,02), sintomas (p=0,04), tamanho do tumor maior que cinco centímetros (p=0,04) e mais de três órgãos envolvidos (p=0,003) foram fatores significativamente associados a cirurgia não curativa. CONCLUSÕES: As taxas de morbidade foram maiores no grupo paliativo, e o tempo mediano de sobrevida foi menor no grupo paliativo do que no grupo curativo, entretanto esta diferença na sobrevida não teve significância estatística. Estádio avançado, sintomas, tamanho tumoral e número de órgãos envolvidos são fatores que devem ser levados em consideração na indicação de resgate cirúrgico.

Challenges in surgical oncology training in Brazil: From history to a board-certified specialization.

The Brazilian Society of Surgical Oncology was established over 30 years ago. Despite that, surgical oncology was finally recognized as a Board-Certified medical specialty in 2017 and has strengthened its role in the standardization of surgical and multimodal approaches in our country. This article aims to describe the process and the main challenges of the specialists training who are qualified for job opportunities and who meet the expectations of the recently created competence matrix for surgical oncologists in Brazil. Thus, we hope to expose the challenges of teaching surgical oncology, describe its history and experiences in important country services, and outline the minimum requirements for creating a more humanistic surgical oncologist who is updated and fully committed with multidisciplinary treatment for cancer patients. We conclude that the main characteristic that the surgical oncologist must have is the ability to offer holistic treatments to the patient, based on the highest level of evidence, love, and compassion, to direct the treatment and understand all of the afflictions that arise with a cancer diagnosis. Moreover, the surgical oncologist in training and in the field must be continuously updating himself to offer the best options of treatment to patients.

A proposal of Brazilian Society of Surgical Oncology (BSSO/SBCO) for standardizing cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) procedures in Brazil: pseudomixoma peritonei, appendiceal tumors and malignant peritoneal mesothelioma

Cytoreductive surgery plus hypertermic intraperitoneal chemotherapy has emerged as a major comprehensive treatment of peritoneal malignancies and is currently the standard of care for appendiceal epithelial neoplasms and pseudomyxoma peritonei syndrome as well as malignant peritoneal mesothelioma. Unfortunately, there are some worldwide variations of the cytoreductive surgery and hypertermic intraperitoneal chemotherapy techniques since no single technique has so far demonstrated its superiority over the others. Therefore, standardization of practices might enhance better comparisons between outcomes. In these settings, the Brazilian Society of Surgical Oncology considered it important to present a proposal for standardizing cytoreductive surgery plus hypertermic intraperitoneal chemotherapy procedures in Brazil, with a special focus on producing homogeneous data for the developing Brazilian register for peritoneal surface malignancies.

RESUMO A cirurgia citorredutora com quimioterapia intraperitoneal hipertérmica emergiu como um importante tratamento das neoplasias peritoneais e é, atualmente, o padrão de atendimento para neoplasias epiteliais do apêndice associadas à síndrome de pseudomixoma peritoneal, bem como para o mesotelioma peritoneal maligno difuso. No mundo, existem algumas variações reconhecidas das técnicas de cirurgia citorredutora e quimioterapia intraperitoneal hipertérmica, entretanto nenhuma técnica até agora demonstrou sua superioridade sobre o outra. Portanto, a padronização destes procedimentos poderia melhorar a prática clínica e permitir a comparação adequada entre os resultados. Neste cenário, a Sociedade Brasileira de Cirurgia Oncológica considera importante a apresentação de uma proposta de padronização de procedimentos de cirurgia citorredutora com quimioterapia intraperitoneal hipertérmica no Brasil, com um foco especial na produção de dados homogêneos para o desenvolvimento do registro brasileiro das neoplasias peritoneais.

Análise epidemiológica dos adenocarcinomas gástricos ressecados em um serviço de cirurgia oncológica / Epidemiological analysis of resected gastric adenocarcinomas in a oncologic surgery service

Introdução: O adenocarcinoma de estômago é a quarta neoplasia mais incidente no mundo e a segunda causa de morte relacionada ao câncer. O objetivo deste estudo é determinar o perfil epidemiológico e patológico dos pacientes intervidos cirurgicamente por adenocarcinoma gástrico e sua sobrevida relacionada à classificação TNM. Métodos:Estudo de coorte histórica de 216 pacientes submetidos à gastrectomia por adenocarcinoma gástrico. Foram analisados dados epidemiológicos, patológicos e a sobrevida. Resultados: A média de idade foi de 61,84 anos. Foram 76 (35,2%) pacientes do gênero feminino e 140 (64,8%), masculino. Quanto à localização, 79 (36,6%) no antro, 45 (20,8%) na cárdia, 70 (32,4%) no corpo. Em relação à diferenciação celular, 5 (2,3%) bem diferenciados, 71 (32,9%) moderadamente diferenciados, 133 (61,6%) pouco diferenciados e 7 (3,2%) eram indeterminados. O estadiamento clínico demonstrou 11 (5,1%) pacientes com estádio 0, com sobrevida de 100%; 23 (10,6%) no estádio I, com sobrevida de 82%; 55 pacientes (25,5%), com sobrevida de 60% no estádio II; 101 pacientes (46,7%), com sobrevida de 25% no estádio III e 26 pacientes (12%), com sobrevida de 15% no estádio IV. Em relação às complicações pós-operatórias, 52,3% dos pacientes não tiveram complicações e 7,9% (17 pacientes) com óbito no período pós-operatório. Conclusões: Aproximadamente 70% das neoplasias eram distais, enquanto cerca de 30% eram proximais. A grande parte dos pacientes era de estádios mais avançados, o que conferiu um pior prognóstico, refletindo a necessidade de uma revisão das políticas públicas para câncer gástrico do Brasil, visando aprimorar o diagnóstico e tratamento, melhorando o prognóstico desses pacientes.

Introduction:The gastric adenocarcinoma is the fourth most frequent cancer worldwide and the second leading cause of cancer-related death. The aim of this study is to determine the epidemiological and pathological profile of gastric adenocarcinoma patients and their survival regarding the TNM classification. Methods: A historical cohort study of 216 patients undergoing gastrectomy for gastric adenocarcinoma. Epidemiological, pathological and survival data were analyzed. Results: The mean age was 61.84 years. There were 76 (35.2%) females and 140 (64.8%) males. Regarding location, 79 (36.6%) cases were in the antrum, 45 (20.8%) in the cardia, and 70 (32.4%) in the body. Regarding cell differentiation, 5 cases (2.3%) were well differentiated, 71 (32.9%) moderately differentiated, 133 (61.6%) poorly differentiated, and 7 (3.2%) were indeterminate. Clinical staging showed 11 (5.1%) patients with stage 0 with a survival rate of 100%, 23 (10.6%) in stage I with a survival rate of 82%, 55 patients (25.5%) in stage II with a survival rate of 60%,101 patients (46,7%) in stage III with a survival rate of 25% and 26 patients (12%) in stage IV with a survival rate of 15%. Regarding postoperative complications, 52.3% of the patients had no complications and 7.9% (17 patients) died in the postoperative period. Conclusions: Approximately 70% of tumors were distal, while approximately 30% were proximal. The majority of patients had more advanced stages, which conferred a worse prognosis, reflecting the need for a revision of public policies for gastric cancer in Brazil, aiming to improve the diagnosis and treatment and determining a better prognosis for these patients.

Outcomes of Liver Resection in the Elderly: Is it safe?

BACKGROUND/AIMS: There has been an increase in the incidence of neoplasms of the liver in recent years, although there is still a fear of performing aggressive surgical procedures in elderly patients, especially regarding hepatic surgery. The objective of this study was to analyse the influence of age on the morbidity and mortality of patients undergoing hepatic resection. METHODOLOGY: This was a study of 414 patients who underwent 447 hepatic resections between November 1993 and December 2010. The patients were divided into two groups according to whether they were ≤ 65 or > 65 years of age. RESULTS: The elderly group included 113 resections, while the young group was composed of 334 procedures. The elderly group had more malignant lesions and more comorbidities. With regard to the transoperative and post-operative data, the two groups displayed similar results. According to the multivariate analysis, cirrhosis and the use of transoperative pedicular clamping were independent predictors of morbidity. Cirrhosis was also an independent predictor of mortality. CONCLUSIONS: The results indicate that age is not a predisposing factor for the worsening of results of hepatic resection in selected patients, especially with regard to cirrhosis. Moreover, surgeons must avoid the use of transoperative pedicular clamping.

[Liver ressection in elderly patients]. / Hepatectomia em pacientes idosos.

INTRODUCTION: Life expectancy of the population has increased in recent years as a result of human development, leading to an increase in the incidence of primary and secondary neoplasms of the liver. Medicine has been following this process, but there is still fear of aggressive surgical treatment in elderly patients, especially concerning to liver surgery. AIM: To analyze the influence of age on the morbidity and mortality of patients undergoing liver resection. METHOD: Literature review of scientific articles available in PubMed, Scielo and Bireme database with "elderly", "hepatectomy," "hepatic resection," "postoperative complications", "morbidity", "mortality". It was selected studies that compared the results of hepatectomy between groups of young and elderly patients. CONCLUSION: Age is not a predisposing factor for the worsening of results in liver resection.

METHOD: Literature review of scientific articles available in PubMed, Scielo and Bireme database with "elderly", "hepatectomy," "hepatic resection," "postoperative complications", "morbidity", "mortality". It was selected studies that compared the results of hepatectomy between groups of young and elderly patients. CONCLUSION: Age is not a predisposing factor for the worsening of results in liver resection.

Dermatofibrossarcoma protuberans: experiência e discussão numa série de casos / Dermatofibrosarcoma protuberans: experience and analysis of a clinical series

Introdução: Os dermatofibrossarcomas protuberans são tumores malignos da pele que, por serem pouco frequentes e de variadas apresentações, muitas vezes têm negligenciado o diagnóstico e a terapêutica, resultando principalmente em altas taxas de recidiva e, eventualmente, em maior mortalidade. O objetivo é avaliar dados epidemiológicos de pacientes portadores desta neoplasia e analisar os fatores determinantes da sua recidiva local. Métodos: Estudo retrospectivo de 19 casos, num período de dez anos, tratados no Hospital Santa Rita da Santa Casa de Misericórdia de Porto Alegre com tratamento estatístico. Resultados: Foi verificada a recidiva em 5 pacientes, correspondendo a 26,5% da amostra, sem registro de óbito. Foram analisadas as variáveis: localização, tamanho, estadiamento e margens cirúrgicas, sendo a última estatisticamente significativa. (p<0,03). Conclusão: Embora ainda não haja consenso na literatura quanto à extensão das margens de ressecção nos dermatofibrossarcomas protuberans, certamente margens inferiores a 1 centímetro, como as preconizadas para outros tumores cutâneos, incluindo alguns melanomas, são inadequadas.

Introduction: Dermatofibrosarcoma protuberans (DFSP) are malignant tumors of the skin. Because they are infrequent and have varied presentations, they are often underdiagnosed and remain untreated, leading to high rates of recurrence and occasionally higher mortality. The aim here is to evaluate epidemiological data of patients with this neoplasia and to analyze the determinants of its local recurrence. Methods: A retrospective study with statistical analysis of 19 patients with DFSP treated at the Hospital Santa Rita, Santa Casa de Misericordia de Porto Alegre over a period of ten years. Results: There was a recurrence in 5 patients, representing 26.5% of sample, with no record of death. We analyzed the following variables: location, size, stage and surgical margins, the latter being statistically significant (p <0.03). Conclusion: Although there is yet no consensus in the literature about the extent of resection margins in dermatofibrosarcoma protuberans, certainly margins less than 1.0 cm, as suggested for other skin tumors, including some melanomas, are inadequate.
