Uterine Transplantation with Robot-assisted Uterus Retrieval from Living Donor: First Case in Brazil.

OBJECTIVE: To present the first robot-assisted uterus retrieval from a living donor for uterine transplantation in Brazil. DESIGN: Stepwise demonstration of the technique with narrated video footage. SETTING: A uterine transplantation was performed in a 33-year-old patient with Mayer-Rokitansky-Küster-Hauser syndrome. The donor was a 50-year-old woman who underwent a robotic-assisted uterus retrieval. The procedure was held at Barretos Cancer Hospital, Barretos, Sao Paulo, Brazil. INTERVENTIONS: After approval from the national and local institutional review board, the protocol was submitted to ClinicalTrials.gov (NCT04249791), and the first case was performed. The screening of the patients was done. The uterus was retrieved through a Pfannenstiel incision to avoid complications to the uterine vessels. Uterus was transplanted in the recipient by end-to-end anastomosis of the internal iliac arteries and end-to-side anastomosis of the external iliac vein with a gonadal vein from the infundibulopelvic ligament. Surgical intraoperative parameters were measured. The docking time was 4 minutes. Robotic donor surgery took 400 minutes, bench surgery took 62 minutes, and laparotomic recipient surgery was completed in 240 minutes. There were no intraoperative complications. The donor patient was discharged from the hospital in 48 hours and the recipient patient in 5 days. CONCLUSION: To the best of our knowledge, this is the first case in Brazil of uterine transplantation with a living donor. Traditionally, patients who undergo uterine transplantation by minimally invasive surgery are managed by laparoscopy. This video demonstrates a feasible robotic approach to uterine transplantation with superior imaging affording a 3-dimensional vision and stabilization of instruments allowing wrist-like movements.

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.

A randomized clinical trial of a new anti-cervical stenosis device after conization by loop electrosurgical excision.

BACKGROUND: The complications inherent to conization include vaginal bleeding, cervical stenosis, amenorrhea, dysmenorrhea, and deep dyspareunia. Cervical stenosis is the most important complication due to the clinical repercussions. Studies show rates of cervical stenosis ranging from 1.3 to 19% after the Loop Electrosurgical Excision Procedure (LEEP). OBJECTIVE: Our primary outcome was to compare the role of a new endocervical device to prevent cervical stenosis after LEEP in patients with high-grade squamous intraepithelial lesions (HSILs). METHODS: A randomized clinical trial was performed including phases II and III for evaluation of a new device for cervical stenosis prevention. In Phase II, we included 25 patients who underwent LEEP and placement of the device to assess its toxicity and efficacy. In phase III, we compared two groups (with and without the use of an anti-stenosis device) to evaluate its efficacy and safety. RESULTS: From August 2015 to June 2018, 265 participants were randomized (Phase II: 25, Phase III: 120 with DUDA and 120 without DUDA). The toxicity during phase II was observed in only one patient (4%) with pain grade > 7. There were 7 cases of toxicity during Phase III, 2 in the DUDA group (1.8%), and 5 in the No DUDA group (4.5%). The complications rate was numerically higher in the No DUDA group (2.5x higher) than the DUDA group, but this difference did not reach statistical significance (p = 0.52). The rate of cervical stenosis in DUDA group was (4-7,3%), and in No DUDA group was (4.3-5.8%) (p = 0.5). We did not find a significant difference when comparing the evolution at 3, 6, and 12 months in terms of cervical patency and visualization of the squamocolumnar junction (SCJ) during colposcopy. The DUDA group exhibited 15% to 19% nonvisualization of the SCJ, whereas that rate ranged from 10 to 12% in the No DUDA group. CONCLUSIONS: The rate of cervical stenosis was not different comparing the use of a new device, specifically produced to prevent cervical stenosis, compared to no use after LEEP procedure. This clinical trial opens up space for a discussion of the utility of using cervical stenosis devices after LEEP. Perhaps in another type of conization it can be evaluated to avoid cervical stenosis.

Chemoradiation for cervical cancer treatment portends high risk of pelvic floor dysfunction.

GOAL: To assess the impact of chemoradiation on pelvic floor (PF) muscle function after the treatment of cervical cancer (CC). METHODS: We performed a prospective cohort study of women between the ages of 20 and 70 years old who had a diagnosis of CC. Patients were treated with chemoradiation at the Barretos Cancer Hospital (BCH), between August 2016 and July 2017. We performed three evaluations at different time points after chemoradiation treatment to compare changes in muscle function. Pelvic floor muscle function was assessed through perineometry (PNM) and surface electromyography (EMG) at the following time points: Pretreatment Moment 1 (M1): evaluated before chemoradiation; Moment 2 (M2): at the first follow-up medical visit (usually 3 to 4 months after treatment); and Moment 3 (M3): at the second follow-up medical visit (usually after 6 to 9 months after treatment). Mean vaginal squeeze pressure levels were determined by PNM and muscle electromyographic activity by EMG and the results were evaluated by Generalized Linear Model comparisons. RESULTS: Forty-nine patients were evaluated at M1; 35 at M2; and 32 at M3, so that 32 patients had all three muscle evaluations performed. There was a statistically significant increase in the frequency of women with urgency urinary incontinence at the M2 evaluation time (41.9%), compared to pretreatment M1 (18.6%), p<0.001. The means of the vaginal squeeze pressures reduced through M1 to M3 in the phasic (M1: 17.7 mmHg; M3: 11.27mmHg) and tonic contractions (M1: 10.56 mmHg; M3: 7.52mmHg), p = 0.01 and p = 0.03 respectively. There was no difference in pelvic floor function in the three evaluations M1-M3, measured by EMG. The pelvic floor strength assessed by PMN and their interactions with anthropometric, parity and hormonal status variables, showed that a high body mass index (BMI) significantly influenced decreases in pelvic floor muscle function before and after treatment. CONCLUSION: These results show that chemoradiation causes reduction of muscle function of the pelvic floor, especially in the late phase after the end of treatment. Both the high BMI and urgent urinary incontinence symptoms were related to decreased muscle strength.

Detection of HPV E6 oncoprotein from urine via a novel immunochromatographic assay.

Cervical cancer is a significant public health problem, especially in low- and middle-income countries, where women have little access to cervical cancer screening; consequently 80% of cervical cancer related mortality occurs in these regions. The development of screening methods that need less infrastructure thus represents an urgent medical need. The study aims to compare the detection rates of high-risk human papillomavirus 16 and 18 E6 oncoprotein in urine, vaginal self-collected, and cervical scrapes of women using the OncoE6™ Cervical Test and compare the HPV16 and/or HPV18 E6 detection rates with the HPV DNA testing. Paired urine, vaginal self-collected and cervical specimens were collected from 124 women who participated in cervical cancer screening or treatment in this proof-of-concept study and underwent to HPV16/18-E6 testing and high-risk HPV DNA testing prior to treatment of cervical neoplasia or cancer. Concordance between urinary, vaginal and cervical HPV16/18-E6 and HPV-DNA testing was evaluated for patients classified as negative group (

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.

Squamous differentiation portends poor prognosis in low and intermediate-risk endometrioid endometrial cancer.

BACKGROUND: Endometrial cancer presents well-defined risk factors: myometrial invasion, histological subtype, tumor grade, lymphovascular space invasion (LVSI). Some low and intermediate-risk endometrioid endometrial cancer patients exhibited unexpected outcomes. This study aimed to investigate other clinical-pathological factors that might influence the recurrence rates of patients diagnosed with low and intermediate-risk endometrioid endometrial cancer. METHODS: A case-control study from a cohort retrospective of 196 patients diagnosed with low and intermediate-risk endometrioid endometrial cancer at a single institution from 2009 to 2014 was conducted. Medical records were reviewed to compare clinical (race, smoking, menopause age, body mass index) and pathological (endometrioid vs endometrioid with squamous differentiation, tumor differentiation grade, tumor location, endocervical invasion, LVSI) features of patients with recurrence (case) and without recurrence (control) of disease. Three controls for each case were matched for age and staging. RESULTS: Twenty-one patients with recurrence were found (10.7%), of which 14 were stage IA, and 7 were stage IB. In accordance, 63 patients without recurrence were selected as controls. There were no significant differences in any clinical characteristics between cases and controls. Among pathological variables, presence of squamous differentiation (28.6% vs. 4.8%, p = 0.007), tumor differentiation grade 2 or 3 (57.1% vs. 30.2%, p = 0.037) and presence of endocervical invasion (28.6% vs. 12.7%, p = 0.103) were associated with disease recurrence on a univariate analysis. On multivariable analysis, only squamous differentiation was a significant risk factor for recurrence (p = 0.031). CONCLUSION: Our data suggest that squamous differentiation may be an adverse prognostic factor in patients with low and intermediate-risk endometrioid endometrial cancer, that showed a 5.6-fold increased risk for recurrence.

Melanoma characteristics in Brazil: demographics, treatment, and survival analysis.

BACKGROUND: The incidence of melanoma, one of the most aggressive of the skin cancers, has been increasing worldwide in the last few decades. Data from Latin America and Brazil remain scarce. We aimed to describe the demographic, clinical, and histopathological data; therapy characteristics; and survival rates of the Brazilian melanoma patient population. RESULTS: We collected and analysed retrospective data from 15 years at a tertiary cancer centre. We describe patient characteristics and treatment. We calculated survival, and identified the main prognostic factors through univariate and multivariate analysis. We analysed a total of 1073 patients, with a mean age of 56.7 years. Men and women experienced similar prevalence, and 91.2% of patients had white skin. The most prevalent subtype was superficial spreading, and the most prevalent anatomic location was the trunk (32.2%), followed by the lower extremities (28%). Of all cases, 567 (52.9%) were assigned to clinical stages I and II, while 382 (32.6%) were stages III and IV. Surgery was the main treatment. Sentinel node biopsy was performed in 373 patients, with 23.8% positivity. Overall actuarial 5-year survival was 67.6%. Multivariate analysis showed that gender, serum lactate dehydrogenase (LDH) levels at diagnosis; anatomic location, TNM stage, and local recurrence were significant prognostic factors. CONCLUSIONS: Overall survival was lower than worldwide rates. The main factors influencing survival were similar to those in other populations. Local recurrence was independently associated with lower survival rates. The high prevalence of advanced cases reinforces the importance of strategies to diagnose melanomas in the early stages. There is a need for future multi-institutional prospective studies to attain a better understanding of possible socioeconomic and other influences on survival among melanoma populations in Brazil and Latin America.

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

Retalho de glândula submandibular na reconstrução de defeitos da cavidade oral e orofaringe em cirurgias oncológicas de cabeça e pescoço: Descrição da técnica e resultados iniciais / Submandibular gland flap for reconstruction of oral cavity and oropharynx after head and neck oncologic surgery: Technique and initial results

Introdução: Um dos grandes avanços modernos na cirurgia de cabeça e pescoço foi a introdução das técnicas de reconstrução na especialidade, que ampliou as possibilidades de ressecção radical e reconstrução imediata. A utilização da rotação do retalho da glândula submandibular foi descrito para correção cirúrgica da laringe e hipofaringe. Entretanto, não encontramos descrita na literatura a utilização desse retalho para correção de defeitos cirúrgicos da cavidade oral e orofaringe em cirurgias oncológicas de cabeça e pescoço. Objetivo: Descrever a técnica de rotação do retalho de glândula submandibular para reconstrução de defeito cirúrgico na cavidade oral e orofaringe e os resultados dessa reconstrução. Métodos: Este é um estudo retrospectivo que inclui 16 pacientes submetidos ao retalho da glândula submandibular entre setembro de 2007 a fevereiro de 2009. Resultados: A maioria dos pacientes era do gênero masculino, com idade média de 55 anos. Encontramos 43,75% T3; e 56,25% T4. Oito pacientes (50%) apresentavam-se com linfonodos metastáticos. Houve seis (37,5%) complicações locais: um seroma, uma deiscência parcial e osteonecrose, uma fístula salivar e três infecções. No seguimento, um paciente apresentou recidiva local e um caso de recidiva cervical em partes moles. Conclusão: A rotação do retalho de glândula submandibular é factível e viável para correção de defeitos cirúrgicos da cavidade oral e orofaringe, apresentando baixa morbidade e sendo realizada em tempo cirúrgico satisfatório. Essa técnica pode ser considerada uma opção de reconstrução, em casos selecionados, sem comprometer o caráter oncológico das cirurgias.

Introdution: One of the greatest advances in the modern era of head and neck surgery was the introduction of reconstructive techniques, which allowed for larger oncological resections followed by immediate reconstruction. The use of submandibular gland flap has been described for surgical defect in larynx and hypopharynx. However, we did not find its use for oral cavity surgical and oropharynx defects after head and neck oncologic surgery. Objective: To describe the technique of the submandibular gland flap for oral cavity and oropharynx reconstruction and its preliminary results. Methods: This is a retrospective study including 16 patients who underwent this reconstruction during the period from September 2007 to February 2009. Results: The majority of the cases were men with an average age of 55 years. There were staged as T3 in 43.75%; and 56.25% T4. Eight patients (50%) presented with lymph node metastasis. We observed 6 (37.5%) local postoperative complications being 1 seroma, 1 fistula, 3 local infections and 1 partial dehiscence with osteonecrose. During the follow up period 1 patient presented with local tumor recurrence and 1 regional recurrence was observed. Conclusion: The submandibular gland flap is feasible for selected oral cavity surgical and oropharynx defects presenting with low morbidity and in a reasonable time. This technique could be considered as an option for selected cases after head and neck oncologic surgery.

Divertículo de Meckel: relato de caso / Meckel diverticulum: a case report

O divertículo de Meckel (DM) é a mais prevalente anomalia do trato gastrointestinal, sendo mais encontrado no sexo masculino. Incide em 2por cento da população geral, com taxa de complicações ao longo da vida de 4por cento a qual vai diminuindo com a idade. Os autores descrevem o caso de um menino de um ano e sete meses com história de melena e enterorragia com evolução de seis meses. Durante a descrição do caso, os autores confirmam a maior sensibilidade da cintilografia para diagnóstico de DM. Embora o DM seja uma patologia relativamente rara em crianças, dentre as anormalidades congênitas é a mais freqüente. Isso justifica a descrição deste relato de caso
