RESUMEN

OBJECTIVES: To evaluate the prevalence of post-operative complications and quality of life (QoL) related to sentinel lymph node (SLN) biopsy vs systematic lymphadenectomy in endometrial cancer. METHODS: A prospective cohort included women with early-stage endometrial carcinoma who underwent lymph node staging, grouped as follows: SLN group (sentinel lymph node only) and SLN+LND group (sentinel lymph node biopsy with addition of systematic lymphadenectomy). The patients had at least 12 months of follow-up, and QoL was assessed by European Organization for Research and Treatment of Cervical Cancer Quality of Life Questionnaire 30 (EORTC-QLQ-C30) and EORTC-QLQ-Cx24. Lymphedema was also assessed by clinical evaluation and perimetry. RESULTS: 152 patients were included: 113 (74.3%) in the SLN group and 39 (25.7%) in the SLN+LND group. Intra-operative surgical complications occurred in 2 (1.3%) cases, and all belonged to SLN+LND group. Patients undergoing SLN+LND had higher overall complication rates than those undergoing SLN alone (33.3% vs 14.2%; p=0.011), even after adjusting for confound factors (OR=3.45, 95% CI 1.40 to 8.47; p=0.007). The SLN+LND group had longer surgical time (p=0.001) and need for admission to the intensive care unit (p=0.001). Moreover, the incidence of lymphocele was found in eight cases in the SLN+LND group (0 vs 20.5%; p<0.001). There were no differences in lymphedema rate after clinical evaluation and perimetry. However, the lymphedema score was highest when lymphedema was reported by clinical examination at 6 months (30.1 vs 7.8; p<0.001) and at 12 months (36.3 vs 6.0; p<0.001). Regarding the overall assessment of QoL, there was no difference between groups at 12 months of follow-up. CONCLUSIONS: There was a higher overall rate of complications for the group undergoing systematic lymphadenectomy, as well as higher rates of lymphocele and lymphedema according to the symptom score. No difference was found in overall QoL between SLN and SLN+LND groups.

RESUMEN

PURPOSE: To analyze the survival outcomes of patients in a Brazilian cohort who underwent minimally invasive surgery (MIS) compared with open surgery for early stage cervical cancer. METHODS: A multicenter database was constructed, registering 1280 cervical cancer patients who had undergone radical hysterectomy from 2000 to 2019. For the final analysis, we included cases with a tumor ≤ 4 cm (stages Ia2 to Ib2, FIGO 2018) that underwent surgery from January 2007 to December 2017. Propensity score matching was also performed. RESULTS: A total of 776 cases were ultimately analyzed, 526 of which were included in the propensity score matching analysis (open, n = 263; MIS, n = 263). There were 52 recurrences (9.9%), 28 (10.6%) with MIS and 24 (9.1%) with open surgery (p = 0.55); and 34 deaths were recorded, 13 (4.9%) and 21 (8.0%), respectively (p = 0.15). We noted a 3-year disease-free survival (DFS) rate of 88.2% and 90.3% for those who received MIS and open surgery, respectively (HR 1.32; 95% CI: 0.76-2.29; p = 0.31) and a 5-year overall survival (OS) rate of 91.8% and 91.1%, respectively (HR 0.80; 95% CI: 0.40-1.61; p = 0.53). There was no difference in 3-year DFS rates between open surgery and MIS for tumors ≤ 2 cm (95.7% vs. 90.8%; p = 0.16) or > 2 cm (83.9% vs. 85.4%; p = 0.77). Also, the 5-year OS between open surgery and MIS did not differ for tumors ≤ 2 cm (93.1% vs. 93.6%; p = 0.82) or > 2 cm (88.9% vs. 89.8%; p = 0.35). CONCLUSIONS: Survival outcomes were similar between minimally invasive and open radical hysterectomy in this large retrospective multicenter cohort.

RESUMEN

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.

RESUMEN

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.

RESUMEN

BACKGROUND: Growing evidence suggest that sentinel lymph node (SLN) biopsy in endometrial cancer accurately detects lymph node metastasis. However, prospective randomized trials addressing the oncological outcomes of SLN biopsy in endometrial cancer without lymphadenectomy are lacking. PRIMARY OBJECTIVES: The present study aims to confirm that SLN biopsy without systematic node dissection does not negatively impact oncological outcomes. STUDY HYPOTHESIS: We hypothesized that there is no survival benefit in adding systematic lymphadenectomy to sentinel node mapping for endometrial cancer staging. Additionally, we aim to evaluate morbidity and impact in quality of life (QoL) after forgoing systematic lymphadenectomy. TRIAL DESIGN: This is a collaborative, multicenter, open-label, non-inferiority, randomized trial. After total hysterectomy, bilateral salpingo-oophorectomy and SLN biopsy, patients will be randomized (1:1) into: (a) no further lymph node dissection or (b) systematic pelvic and para-aortic lymphadenectomy. MAJOR INCLUSION AND EXCLUSION CRITERIA: Inclusion criteria are patients with high-grade histologies (endometrioid G3, serous, clear cell, and carcinosarcoma), endometrioid G1 or G2 with imaging concerning for myometrial invasion of ≥50% or cervical invasion, clinically suitable to undergo systematic lymphadenectomy. PRIMARY ENDPOINTS: The primary objective is to compare 3-year disease-free survival and the secondary objectives are 5-year overall survival, morbidity, incidence of lower limb lymphedema, and QoL after SLN mapping ± systematic lymphadenectomy in high-intermediate and high-risk endometrial cancer. SAMPLE SIZE: 178 participants will be randomized in this study with an estimated date for completing accrual of December 2024 and presenting results in 2027. TRIAL REGISTRATION NUMBER: NCT03366051.

RESUMEN

OBJECTIVE: Uterine transposition has emerged as an alternative for fertility preservation in women with pelvic malignancies that require radiotherapy. The goal of this study was to evaluate the short-term outcomes of patients undergoing uterine transposition after trachelectomy for cervical cancer or before chemoradiation for vaginal cancer. METHODS: We retrospectively evaluated patients with early stage cervical cancer after radical trachelectomy or with vaginal cancer with indication for pelvic radiation who had uterine transposition performed as fertility sparing strategy. RESULTS: Four patients with cervical cancer and one patient with vaginal cancer were included. Median age was 32 years (range 28-38). All patients had squamous cell carcinomas. All patients with cervical cancer had radical trachelectomies with sentinel lymph node dissection (SLN). Two of these patients also had pelvic lymphadenectomies. Indications for adjuvant radiotherapy was due to Sedlis criteria in two patients and to lymph node metastasis in the other two patients. The patient with stage IIB vaginal cancer was recommended primary chemoradiation. All patients underwent uterine transposition before radiotherapy. The median uterine transposition surgical time was 90 min (range 80-205) and no early complications (30 days) occurred. Average time from uterine transposition to start of radiotherapy was 16 days (10-28). After radiation, the uterus along with the ovaries and tubes were repositioned and the residual cervix sutured to the vagina. One patient declined uterine reimplantation after radiation and underwent a hysterectomy. After a median follow-up of 25 months (range 1-30), all patients were without evidence of disease. All patients with preserved uterus have normal menses after treatment. One patient has attempted to conceive with IVF techniques without success. CONCLUSIONS: Uterine transposition may be an option in selected patients with cervical and vaginal cancers who want to preserve fertility. However, further studies that address its oncological safety and obstetrical outcomes are encouraged.

RESUMEN

OBJECTIVE: Revised staging of patients with locally advanced cervical cancer is based on clinical examination, imaging, and potential surgical findings. A known limitation of imaging techniques is an appreciable rate of understaging. In contrast, surgical staging may provide more accurate information on lymph node involvement. The aim of this prospective study was to evaluate the impact of pre-treatment surgical staging, including removal of bulky lymph nodes, on disease-free survival in patients with locally advanced cervical cancer. METHODS: Uterus-11 was a prospective international multicenter study including patients with locally advanced cervical cancer who were randomized 1:1 to surgical staging (experimental arm) or clinical staging (control arm) followed by primary platinum-based chemoradiation. Patients with histologically proven squamous cell carcinoma, adenocarcinoma, or adenosquamous cancer International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IIB-IVA underwent gynecologic examination and pre-treatment imaging including abdominal computed tomography (CT) and/or abdominal magnetic resonance imaging (MRI). Patients had chest imaging (any of the following: X-ray, CT, or PET-CT). The primary endpoint was disease-free survival and the secondary endpoint was overall survival. An ad hoc analysis was performed after trial completion for cancer-specific survival. Randomization was conducted from February 2009 to August 2013. RESULTS: A total of 255 patients (surgical arm, n=130; clinical arm, n=125) with locally advanced cervical cancer were randomized. Of these, 240 patients were eligible for analysis. The two groups were comparable with respect to patient characteristics. The surgical approach was transperitoneal laparoscopy in most patients (96.6%). Laparoscopic staging led to upstaging in 39 of 120 (33%) patients. After a median follow-up of 90 months (range 1-123) in both arms, there was no difference in disease-free survival between the groups (p=0.084). For patients with FIGO stage IIB, surgical staging is superior to clinical staging with respect to disease-free survival (HR 0.51, 95% CI 0.30 to 0.86, p=0.011). In the post-hoc analysis, surgical staging was associated with better cancer-specific survival (HR 0.61, 95% CI 0.40 to 0.93, p=0.020). CONCLUSION: Our study did not show a difference in disease-free survival between surgical and clinical staging in patients with locally advanced cervical cancer. There was a significant benefit in disease-free survival for patients with FIGO stage IIB and, in a post-hoc analysis, a cancer-specific survival benefit in favor of laparoscopic staging. The high risk of distant metastases in both arms emphasizes the need for further evaluation.

RESUMEN

BACKGROUND: Radical trachelectomy is considered a viable option for fertility preservation in patients with low-risk, early-stage cervical cancer. Standard approaches include laparotomy or minimally invasive surgery when performing radical trachelectomy. PRIMARY OBJECTIVE: To compare disease-free survival between patients with FIGO (2009) stage IA2 or IB1 (≤2cm) cervical cancer who underwent open versus minimally invasive (laparoscopic or robotic) radical trachelectomy. STUDY HYPOTHESIS: We hypothesize that minimally invasive radical trachelectomy has similar oncologic outcomes to those of the open approach. STUDY DESIGN: This is a collaborative, multi-institutional, international, retrospective study. Patients who underwent a radical trachelectomy and lymphadenectomy between January 1, 2005 and December 31, 2017 will be included. Institutional review board approval will be required. Each institution will be provided access to a study-specific REDCap (Research Electronic Data Capture) database maintained by MD Anderson Cancer Center and will be responsible for entering patient data. INCLUSION CRITERIA: Patients with squamous, adenocarcinoma, or adenosquamous cervical cancer FIGO (2009) stages IA2 and IB1 (≤2 cm) will be included. Surgery performed by the open approach or minimally invasive approach (laparoscopy or robotics). Tumor size ≤2 cm, by physical examination, ultrasound, MRI, CT, or positron emission tomography (at least one should confirm a tumor size ≤2 cm). Centers must contribute at least 15 cases of radical trachelectomy (open, minimally invasive, or both). EXCLUSION CRITERIA: Prior neoadjuvant chemotherapy or radiotherapy to the pelvis for cervical cancer at any time, prior lymphadenectomy, or pelvic retroperitoneal surgery, pregnant patients, aborted trachelectomy (intra-operative conversion to radical hysterectomy), or vaginal approach. PRIMARY ENDPOINT: The primary endpoint is disease-free survival measured as the time from surgery until recurrence or death due to disease. To evaluate the primary objective, we will compare disease-free survival among patients with FIGO (2009) stage IA2 or IB1 (≤2cm) cervical cancer who underwent open versus minimally invasive radical trachelectomy. SAMPLE SIZE: An estimated 535 patients will be included; 256 open and 279 minimally invasive radical trachelectomy. Previous studies have shown that recurrence rates in the open group range from 3.8% to 7.6%. Assuming that the 4.5-year disease-free survival rate for patients who underwent open surgery is 95.0%, we have 80% power to detect a 0.44 HR using α level 0.10. This corresponds to an 89.0% disease-free survival rate at 4.5 years in the minimally invasive group.

RESUMEN

BACKGROUND: Surgical staging is associated with a significant rate of upstaging compared to clinical/radiological staging in patients with locally advanced cervical cancer. OBJECTIVE: To analyze the stage-specific percentage of pelvic and para-aortic lymph node metastases and the upstaging ratio in a prospective randomized trial (Uterus-11). METHODS: FIGO stage IIB-IVA cervical cancer patients were randomized to surgical staging (arm A) or to clinical staging and primary chemoradiation (arm B). Arm B patients underwent CT-guided biopsy of suspicious para-aortic lymph nodes. Confirmed para-aortic metastasis patients received extended-field radiation therapy. RESULTS: A total of 234 patients were enrolled, including 120 (arm A) and 114 (arm B) treated per protocol. The groups were well balanced. Pelvic and para-aortic lymph node metastases were identified after surgical staging in 51 and 24% of patients, respectively (p < 0.001). Pelvic and para-aortic lymph node metastases were confirmed in 45 and 20% of IIB patients and in 71 and 37% of IIIB patients, respectively. Upstaging occurred in 39/120 (33%) in arm A and in 9/114 (8%) in arm B (p < 0.001). CONCLUSION: The histological results in both groups led to a considerable rate of upstaging. Oncological data from the Uterus-11 study may reveal whether modified therapy translates into a survival benefit.

RESUMEN

BACKGROUND: Diffusion Weighted (DW) Magnetic Resonance Imaging (MRI) has been studed in several cancers including cervical cancer. This study was designed to investigate the association of DW-MRI parameters with baseline clinical features and clinical outcomes (local regional control (LRC), disease free survival (DFS) and disease specific survival (DSS)) in cervical cancer patients treated with definitive chemoradiation. METHODS: This was a retrospective study approved by an institutional review board that included 66 women with cervical cancer treated with definitive chemoradiation who underwent pre-treatment MRI at our institution between 2012 and 2013. A region of interest (ROI) was manually drawn by one of three radiologists with experience in pelvic imaging on a single axial CT slice encompassing the widest diameter of the cervical tumor while excluding areas of necrosis. The following apparent diffusion coefficient (ADC) values (×10(-3) mm(2)/s) were extracted for each ROI: Minimum - ADCmin, Maximum - ADCmax, Mean - ADCmean, and Standard Deviation of the ADC - ADCdev. Receiver operating characteristic (ROC) curves were built to choose the most accurate cut off value for each ADC value. Correlation between imaging metrics and baseline clinical features were evaluated using the Mann Whitney test. Confirmatory multi-variate Cox modeling was used to test associations with LRC (adjusted by gross tumor volume - GTV), DFS and DSS (both adjusted by FIGO stage). Kaplan Meyer curves were built for DFS and DSS. A p-value < 0.05 was considered significant. Women median age was 52 years (range 23-90). 67 % had FIGO stage I-II disease while 33 % had FIGO stage III-IV disease. Eighty-two percent had squamous cell cancer. Eighty-eight percent received concurrent cisplatin chemotherapy with radiation. Median EQD2 of external beam and brachytherapy was 82.2 Gy (range 74-84). RESULTS: Women with disease staged III-IV (FIGO) had significantly higher mean ADCmax values compared with those with stage I-II (1.806 (0.4) vs 1.485 (0.4), p = 0.01). Patients with imaging defined positive nodes also had significantly higher mean (±SD) ADCmax values compared with lymph node negative patients (1.995 (0.3) vs 1.551 (0.5), p = 0.03). With a median follow-up of 32 months (range 5-43) 11 patients (17 %) have developed recurrent disease and 8 (12 %) have died because of cervical cancer. ROC curves based on DSS showed optimal cutoffs for ADCmin (0.488 × 10(-3)), ADCmean (0.827 × 10(-3)), ADCmax (1.838 × 10(-3)) and ADCdev (0.148 × 10(-3)). ADCmin higher than the cutoff was significantly associated with worse DFS (HR = 3.632-95 % CI: 1.094-12.054; p = 0.035) and DSS (HR = 4.401-95 % CI: 1.048-18.483; p = 0.043). CONCLUSION: Pre-treatment ADCmax measured in the primary tumor may be associated with FIGO stage and lymph node status. Pre-treatment ADCmin may be a prognostic factor associated with disease-free survival and disease-specific survival in cervical cancer patients treated with definitive chemoradiation. Prospective validation of these findings is currently ongoing.

RESUMEN

STUDY OBJECTIVE: To demonstrate a laparoscopic vaginal-assisted nerve-sparing radical trachelectomy. DESIGN: An edited educational video, including a step-by-step description of the procedure. SETTING: Radical trachelectomy is the main surgical indication for selected cases of initial cervical cancer with a fertility-sparing approach. Although transvaginal access is the most traditional route, this technique has not gained widespread acceptance because of the complexity of the ureteral dissection and the limited amount of resected parametrial tissue. This video describes a laparoscopic technique including an adequate parametrial resection with autonomic preservation (C1 level) and a standard laparoscopic ureteric dissection under direct visualization. All parametrial dissections were performed by laparoscopy using a nerve-sparing technique. The uterine vessels were well dissected and transected at their origin. The colpotomy was performed by laparoscopy with a 1-cm vaginal margin using a monopolar energy hook. To achieve an adequate endocervical margin and to avoid thermal injury to the endocervix, the cervical section was performed transvaginally with a cold knife. The specimen was then retrieved, and a segment of the remaining cervix was removed for frozen section analysis. If the margin was free of tumor, the cervical-vaginal anastomosis was performed transvaginally. An endocervical device was placed to avoid postoperative cervical stenosis. INTERVENTIONS: Laparoscopic vaginal-assisted nerve-sparing radical trachelectomy. CONCLUSION: This video demonstrates a reproducible laparoscopic technique for radical trachelectomy with a nerve-sparing technique. The vaginal route was used at the moment of sectioning the cervix/isthmus to permit adequate margin evaluation.

RESUMEN

High-risk human papillomavirus (hrHPV) is an essential cause of cervical carcinoma and is also strongly related to anal cancer development. The hrHPV E6 oncoprotein plays a major role in carcinogenesis. We aimed to evaluate the frequency of hrHPV DNA and E6 oncoprotein in the anuses of women with cervical carcinoma. We analyzed 117 women with cervical cancer and 103 controls for hrHPV and the E6 oncogene. Positive test results for a cervical carcinoma included 66.7 % with hrHPV-16 and 7.7 % with hrHPV-18. One case tested positive for both HPV variants (0.9 %). The samples from the anal canal were positive for HPV-16 in 59.8 % of the cases. Simultaneous presence of HPV in the cervix and anal canal was found in 53.8 % of the cases. Regarding expression of E6 RNA, positivity for HPV-16 in the anal canal was found in 21.2 % of the cases, positivity for HPV-16 in the cervix was found in 75.0 %, and positivity for HPV-18 in the cervix was found in 1.9 %. E6 expression in both the cervix and anal canal was found in 19.2 % of the cases. In the controls, 1 % tested positive for HPV-16 and 0 % for HPV-18. Anal samples from the controls showed a hrHPV frequency of 4.9 % (only HPV16). The presence of hrHPV in the anal canal of women with cervical cancer was detected at a high frequency. We also detected E6 RNA expression in the anal canal of women with cervical cancer, suggesting that these women are at risk for anal hrHPV infection.

RESUMEN

OBJECTIVE: To analyze the relationship between hospitalization and the occurrence of delirium in older adults with physical frailty. METHOD: Cross-sectional study carried out in a public hospital in southern Brazil. Hospitalized older adults aged ≥ 60 years participated. Sociodemographic and clinical data were collected, physical frailty phenotype tests were performed and the Confusion Assessment Method was used. Descriptive analyzes were carried out and odds ratio values were estimated for the frailty and delirium variables. RESULTS: Of the 320 older adults evaluated, 21.14% presented delirium, 49% were identified as pre-frail and 36.2% as frail. Of those affected by delirium, 71.6% were classified as frail and 28.3% as pre-frail (p < 0.001). An association was observed between the occurrence of delirium and frailty (OR 1.22; 95% CI 1.07 to 1.38), age ≥ 80 years (OR 1.14; 95% CI 1.01 to 1.32), epilepsy (OR 1.38; 95% CI 1.09 to 1.76), dementia (OR 1.58; 95% CI 1.37 to 1.82), and history of stroke (OR 1.14; 95% CI 1.03 to 1.26). CONCLUSION: There was a high frequency of pre-frail and frail older adults, and the occurrence of delirium in frail was significantly higher. Special attention should be paid to frail older adults to prevent the occurrence of delirium during hospitalization.

RESUMEN

Introduction: The COVID-19 pandemic has had an unprecedented impact on global health systems and economies. With ongoing and future challenges posed to the field due to the pandemic, re-examining research priorities has emerged as a concern. As part of a wider project aiming to examine research priorities, here we aimed to qualitatively examine the documented impacts of the COVID-19 pandemic on cancer researchers. Materials and Methods: We conducted a literature review with the aim of identifying non-peer-reviewed journalistic sources and institutional blog posts which qualitatively documented the effects of the COVID-19 pandemic on cancer researchers. We searched on 12th January 2021 using the LexisNexis database and Google, using terms and filters to identify English-language media reports and blogs, containing references to both COVID-19 and cancer research. The targeted search returned 751 results, of which 215 articles met the inclusion criteria. These 215 articles were subjected to a conventional qualitative content analysis, to document the impacts of the pandemic on the field of cancer research. Results: Our analysis yielded a high plurality of qualitatively documented impacts, from which seven categories of direct impacts emerged: (1) COVID measures halting cancer research activity entirely; (2) COVID measures limiting cancer research activity; (3) forced adaptation of research protocols; (4) impacts on cancer diagnosis, cases, and services; (5) availability of resources for cancer research; (6) disruption to the private sector; and (7) disruption to supply chains. Three categories of consequences from these impacts also emerged: (1) potential changes to future research practice; (2) delays to the progression of the field; and (3) potential new areas of research interest. Discussion: The COVID-19 pandemic had extensive practical and economic effects on the field of cancer research in 2020 that were highly plural in nature. Appraisal of cancer research strategies in a post-COVID world should acknowledge the potential for substantial limitations (such as on financial resources, limited access to patients for research, decreased patient access to cancer care, staffing issues, administrative delays, or supply chain issues), exacerbated cancer disparities, advances in digital health, and new areas of research related to the intersection of cancer and COVID-19.

RESUMEN

BACKGROUND AND OBJECTIVES: Some authors states that the removal of lymph node would only contribute towards assessing the lymph node status and regional disease control, without any benefit for the patients' survival. The aim of this paper was to assess the influence of the number of surgically dissected pelvic lymph nodes (PLN) on disease-free survival. METHODS: Retrospective cohort study on 42 women presenting squamous cell carcinoma (SCC) of the uterine cervix, with metastases in PLN treated by radical surgery. The Cox model was used to identify risk factors for recurrence. The model variables were adjusted for treatment-related factors (year of treatment, surgical margins and postoperative radiotherapy). The cutoff value for classifying the lymphadenectomy as comprehensive (15 PLN or more) or non-comprehensive (<15 PLN) was determined from analysis of the ROC curve. RESULTS: Fourteen recurrences (32.6%) were recorded: three pelvic, eight distant, two both pelvic and distant, and one at an unknown location. The following risk factors for recurrence were identified: invasion of the deep third of the cervix and number of dissected lymph nodes <15. CONCLUSIONS: Deep invasion and non-comprehensive pelvic lymphadenectomy are possible risk factors for recurrence of SCC of the uterine cervix with metastases in PLN.

RESUMEN

ABSTRACT Objective To analyze the relationship between hospitalization and the occurrence of delirium in older adults with physical frailty. Method Cross-sectional study carried out in a public hospital in southern Brazil. Hospitalized older adults aged ≥ 60 years participated. Sociodemographic and clinical data were collected, physical frailty phenotype tests were performed and the Confusion Assessment Method was used. Descriptive analyzes were carried out and odds ratio values were estimated for the frailty and delirium variables. Results Of the 320 older adults evaluated, 21.14% presented delirium, 49% were identified as pre-frail and 36.2% as frail. Of those affected by delirium, 71.6% were classified as frail and 28.3% as pre-frail (p < 0.001). An association was observed between the occurrence of delirium and frailty (OR 1.22; 95% CI 1.07 to 1.38), age ≥ 80 years (OR 1.14; 95% CI 1.01 to 1.32), epilepsy (OR 1.38; 95% CI 1.09 to 1.76), dementia (OR 1.58; 95% CI 1.37 to 1.82), and history of stroke (OR 1.14; 95% CI 1.03 to 1.26). Conclusion There was a high frequency of pre-frail and frail older adults, and the occurrence of delirium in frail was significantly higher. Special attention should be paid to frail older adults to prevent the occurrence of delirium during hospitalization.

RESUMEN

Gynecologic cancer, cervical cancer in particular, is disproportionately represented in the developing world where mortality is also high. Screening programs, increased availability of chemotherapy, and an awareness of HIV-related cancers have in part accelerated a need for physicians who can treat these cancers, yet the infrastructure for such training is often lacking. In this paper, we address the variations in gynecology oncology training in LMICs as well as the ubiquitous challenges, in an effort to guide future agendas.

RESUMEN

OBJECTIVE: To translate and perform the cultural adaptation of the tool Functional Assessment of Chronic Illness Therapy - Cervical Dysplasia (FACIT-CD) to the Portuguese language. METHODS: A descriptive cross-sectional study, with translation and cultural adaptation of the assessment tool performed according to international guidelines and the Functional Assessment of Chronic Illness Therapy (FACIT) protocol group. It involved eight experts, six from Brazil, one from Portugal and one from the United States. After translation and back-translation of the tool, the semantic analysis process was carried out. We randomly included 20 women aged between 18 and 70 years with altered cervical cytology exam, seen at the Department of Prevention and Gynecologic Oncology - Hospital de Câncer de Barretos. RESULTS: The sample consisted of women with low education level. In the first pre-test, ten women participated and half of them considered the questions CD1, CD2 and CD3 as difficult, because they did not understand the meaning of the term "pelvic area". The question CD5, "I worry about spreading the infection", was also considered difficult to understand by five women. After the reconsideration of the expert committee and FACIT group, the second pre-test was performed. At this stage, we concluded that the previously raised understanding problems had been solved. CONCLUSION: The translated version of FACIT-CD in universal Portuguese language is equivalent to the original version in English and was easily understood by patients with cervical intraepithelial neoplasia. OBJETIVO: Traduzir e adaptar o instrumento Functional Assessment of Chronic Illness Therapy - Cervical Dysplasia (FACIT-CD), para a língua portuguesa. MÉTODOS: Estudo descritivo, transversal, com metodologia de tradução e adaptação cultural de instrumento de avaliação, realizado por meio de diretrizes internacionais e seguindo o protocolo do grupo Functional Assessment of Chronic Illness Therapy (FACIT). Envolveu oito especialistas, sendo seis nativos do Brasil, um de Portugal e um dos Estados Unidos. Ao término do processo de tradução e retrotradução, deu-se início ao processo de análise semântica. Foram incluídas aleatoriamente 20 mulheres entre 18 e 70 anos com exame de citologia cervical alterado, atendidas no Departamento de Prevenção e Ginecologia Oncológica do Hospital de Câncer de Barretos. RESULTADOS: A amostra foi composta por mulheres com baixa escolaridade. No primeiro pré-teste participaram dez mulheres, sendo que a metade considerou as questões CD1, CD2 e CD3 difíceis por não compreenderem o significado do termo "região pélvica". A questão CD5, "Estou preocupada em disseminar a infecção", também foi considerada de difícil entendimento por cinco mulheres. Após as reconsiderações do comitê de especialistas e do grupo FACIT, foi realizado o segundo pré-teste. Nesta fase, pode-se concluir que os problemas de entendimento anteriores foram resolvidos. CONCLUSÃO: A versão traduzida do FACIT-CD é equivalente à versão original em inglês e em língua portuguesa universal, sendo facilmente compreendida pelas pacientes com neoplasia intraepitelial cervical.
