The Role of Pelvic Exenteration in Cervical Cancer: A Review of the Literature.

Pelvic exenteration represents a radical procedure aimed at achieving complete tumor resection with negative margins. Although it is the only therapeutic option for some cases of advanced tumors, it is associated with several perioperative complications. We believe that careful patient selection is related to better oncologic outcomes and lower complication rates. The objectives of this review are to identify the most current indications for this intervention, suggest criteria for case selection, evaluate recommendations for perioperative care, and review oncologic outcomes and potential associated complications. To this end, an analysis of English language articles in PubMed was performed, searching for topics such as the indication for pelvic exenteration for recurrent gynecologic neoplasms selection of oncologic cases, the impact of tumor size and extent on oncologic outcomes, preoperative and postoperative surgical management, surgical complications, and outcomes of overall survival and recurrence-free survival.

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 guidelines for surgical treatment of endometrial cancer in regions with limited resources.

BACKGROUND: Approximately 70% of cancer-related deaths occur in low- and middle-income countries. In addition to social and racial inequalities, treatment options in these countries are usually limited because of the lack of trained staff and equipment, limited patient access to health services, and a small number of clinical guidelines. OBJECTIVES: The Brazilian Society of Surgical Oncology developed this guideline to address these barriers and guide physicians treating patients with endometrial cancer (EC) in regions with limited resources and few specialized centers. METHODS: The guideline was prepared from 10 January to 25 October 20192019 by a multidisciplinary team of 56 experts to discuss the main obstacles faced by EC patients in Brazil. Thirteen questions considered critical to the surgical treatment of these patients were defined. The questions were assigned to 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 for presentations in meetings, classified the level of evidence, and voted on the recommendations. RESULTS: For all questions including staging, fertility spearing treatment, genetic testing, sentinel lymph node use, surgical treatment, and other clinical relevant questions, major agreement was achieved by the participants, always using accessible alternatives. CONCLUSIONS: It is possible to provide adequate treatment for most EC patients in resource-limited areas, but the first option should be referral to specialized centers with more resources.

Ovarian Sertoli-Leydig Cell Tumors: Epidemiological, Clinical and Prognostic Factors.

OBJECTIVE: To describe a series of cases of ovarian Sertoli-Leydig cell tumors (SLCTs). METHODS: Retrospective review of 12 cases of SLCT treated at the Hospital do Câncer de Barretos, Barretos, state of São Paulo, Brazil, between October 2009 and August 2017. RESULTS: The median age of the patients was 31 years old (15-71 years old). A total of 9 patients (75.0%) presented symptoms: 8 (66.7%) presented with abdominal pain, 5 (41.7%) presented with abdominal enlargement, 2 (16.7%) presented with virilizing signs, 2 (16.7%) presented with abnormal uterine bleeding, 1 (8.3%) presented with dyspareunia, and 1 (8.3%) presented with weight loss. The median preoperative lactate dehydrogenase (LDH) was 504.5 U/L (138-569 U/L), alpha-fetoprotein (AFP) was 2.0 ng/ml (1.1-11.3 ng/ml), human chorionic gonadotropin (ß-hCG) was 0.6 mUI/ml (0.0-2.3 mUI/ml), carcinoembryonic antigen (CEA) was 0.9 ng/ml (0.7-3.4 ng/ml), and cancer antigen 125 (CA-125) was 26.0 U/ml (19.1-147.0 U/ml). All of the tumors were unilateral and surgically treated. Lymphadenectomy was performed in 3 (25.0%) patients, but none of the three patients submitted to lymphadenectomy presented lymph node involvement. In the anatomopathological exam, 1 (8.3%) tumor was well-differentiated, 8 (66.7%) were moderately differentiated, and 3 (25.0%) were poorly differentiated. A total of 5 (55.6%) tumors were solid-cystic, 2 (22.2%) were purely cystic, 1 (11.1%) was cystic with vegetations, and 1 (11.1%) was purely solid, but for 3 patients this information was not available. The median lesion size was 14.2 cm (3.2-23.5 cm). All of the tumors were at stage IA of the 2014 classification of the International Federation of Gynecology and Obstetrics (FIGO). A total of 2 (16.7%) patients received adjuvant treatment; 1 of them underwent 3 cycles of paclitaxel and carboplatin every 21 days, and the other underwent 4 cycles of ifosfamide, cisplatin and etoposide every 21 days. None of all of the patients had recurrence, and one death related to complications after surgical staging occurred. CONCLUSION: Abdominal pain was the most frequent presentation. There was no ultrasonographic pattern. All of the SLCTs were at stage IA, and most of them were moderately differentiated. Relapses did not occur, but one death related to the surgical staging occurred.

Predictive Factors for Surgical Morbidities and Adjuvant Chemotherapy Delay for Advanced Ovarian Cancer Patients Treated by Primary Debulking Surgery or Interval Debulking Surgery.

OBJECTIVE: Postoperative complications and adjuvant chemotherapy delay (ACD) are the most damaging outcomes after surgical treatment of advanced ovarian cancer. Establishing predictive factors should prevent their occurrence. METHODS: We analyzed retrospectively all patients with advanced ovarian cancer who underwent cytoreduction at our institution between December 2010 and May 2016. We evaluated all 30-day complications and considered ACD all cases who did not start adjuvant chemotherapy until 42 days or did not perform it after cytoreductive surgery. These data were analyzed in the general group, and between primary debulking surgery (PDS) and interval debulking surgery (IDS) using χ test and Student t test. Relationship of variables was verified using Multiple Logistic Regression. RESULTS: A total of 83 women were included. Of these, 43 (51.8%) were submitted to PDS and 40 (48.2%) to IDS. In the PDS group, 23 (53.5%) of the patients had complications. For the IDS group, 27 (67.5%) complicated (P = 0.192). Regarding the general group, independent predictors for 30-day complications were presence of comorbidities (odds ratio [OR], 5.466, 95% confidence interval [CI], 1.151-25,972; P = 0.033) and estimated blood loss of greater than 300 mL (OR, 14.407; 95% CI, 2.736-75.863; P = 0.002). In multivariate analysis of the general group, independent predictors for ACD were the presence of hypertension as comorbidity (OR, 3.898; 95% CI, 1.119-13.578; P = 0.033), body mass index of greater than 30 kg/m (OR, 5.728; 95% CI, 1.169-28.069; P = 0.031), 30-day reoperation (OR, 21.275; 95% CI, 1.799-251.651; P = 0.015), and fever within 30 days (OR, 11.594; 95% CI, 1.714-78.412; P = 0.012). CONCLUSIONS: Comorbidities and intraoperative bleeding are the most relevant findings related to surgical complications. Surgical approach (PDS or IDS) was not related with complications. Surgical complications were significantly related to ACD.

Laparoscopy in uterine cervical cancer. Current state and literature review.

Cervical cancer remains the most frequent gynecological tumor in Brazil and other developing countries. Minimally invasive techniques, especially laparoscopy, have been increasingly employed in such tumors. This article aims to describe the main applications of laparoscopy in the treatment and staging of cervical cancer. In the early stages, it is possible to provide a fertility-preserving surgery in the form of radical trachelectomy and, in a study protocol, the function-preserving surgery, avoiding parametrectomy and the associated morbidity. A fully laparoscopic radical hysterectomy is fairly standard in the literature and has the tendency to become the standard of care in early cases, for patients who want to bear no more children. In advanced stages, minimally invasive surgery can offer ovarian transposition, with intent to prevent actinic castration, without upsetting the time for the start of radiotherapy and chemotherapy. Staging laparoscopic surgery, including pelvic and para-aortic lymphadenectomy, has been the subject of studies, since it has the potential to modify the extension of radiotherapy depending on the extent of lymph node spread.

O câncer de colo uterino permanece o tumor ginecológico mais incidente no Brasil e em diversos países em desenvolvimento. As técnicas minimamente invasivas, principalmente a videolaparoscopia, têm sido progressivamente mais empregadas nestes tumores. Este artigo tem o objetivo de descrever as principais aplicações da videolaparoscopia no tratamento e no estadiamento do câncer de colo. Para os estádios iniciais, é possível oferecer a cirurgia preservadora de fertilidade, na forma de traquelectomia radical e, em protocolo de estudo, na cirurgia conservadora de função, evitando-se a parametrectomia e a morbidade associada. A histerectomia radical totalmente videolaparoscópica está adequadamente padronizada na literatura e tem a tendência de se tornar o padrão de tratamento nos casos iniciais, para pacientes com prole definida. Nos estádios avançados, a cirurgia minimamente invasiva pode oferecer a transposição ovariana, com intenção de evitar a castração actínica, sem prejudicar o tempo para o início do tratamento radioterápico e quimioterápico. A cirurgia laparoscópica estadiadora, incluindo linfadenectomia pélvica e paraórtica, tem sido alvo de estudos, uma vez que tem o potencial de modificar a extensão do tratamento radioterápico, na dependência da extensão da disseminação linfonodal.

Type I and type II endometrial adenocarcinomas: comparative study of ultrasonographic parameters

Objectives: The aim of this study was to compare ultrasonographic aspects of type I and II endometrial adenocarcinomas, seeking to identify differences that could predict the likely histological pattern before curettage. Materials and Methods: This was a retrospective study with 117 women with type I endometrial adenocarcinomas and 17 women with type II, admitted to the Barretos Cancer Hospital,, Barretos, Brazil between February 2007 and December 2009. Patient medical records were reviewed according to standardized form, collecting clinical and histopathologic information in addition to information related to ultrasonographic aspects. Results: The most commonly described ultrasonographic aspect was homogenous myometrium (65.8%), heterogeneous endometrial aspect (66.6%), regular endometrial basal layer (66.6%) and the endometrial cavity not filled by material (51.1%). Myometrial echogenicity proved the only variable in that there was no statistically significant difference, with heterogeneous aspect more frequently found in type II carcinoma (80.0% vs. 27.8%; p=0.039). Conclusions: This study noted few differences between the two groups in reference to ultrasonographic aspects. The only variable that demonstrated statistical significance was myometrial echogenicity. Other studies are necessary for the validation of results presented here
