RESUMO
PURPOSE OF REVIEW: In the past decade, sentinel lymph node (SLN) mapping has progressively substituted full lymphadenectomies in gynecologic oncology. In this article, we review the most relevant and the latest literature on this topic. RECENT FINDINGS: In endometrial and cervical cancer, the current evidence further support the value of indocyanine green (ICG) as tracer of choice for SLN mapping. Experience in vulvar cancer is more limited, with ICG used together with technetium-99 m (Tc-99m) as a dual tracer but ICG, so far, has not been a game changer in this setting as it has been for cervical and endometrial cancer. SUMMARY: For most gynecologic cancers, ICG fluorescence imaging is considered now a days the tracer of choice for lymphatic mapping. However, in early-stage vulvar cancer, SLN biopsy with radioactive tracer continues to be the standard-of-care in lymph node status assessment.

OBJECTIVE: To describe oncologic and obstetric outcomes in patients diagnosed with cervical cancer during pregnancy who had a successful delivery after neoadjuvant chemotherapy. METHODS: A multicenter retrospective review was conducted in 12 institutions from six Latin American countries, between January 2007 and December 2018. Data collected included clinical characteristics, neoadjuvant chemotherapy agents, treatment, obstetric and oncologic outcomes. RESULTS: Thirty-three patients were included. Median age was 34 years (range 31-36). Twenty (60.6%) women were diagnosed at early stage (IB), and 13 (39.4%) with locally advanced stage (IIA-IIIB) according to FIGO 2009 classification. Carboplatin and paclitaxel was the most frequent combination used (60.6%). Partial and complete response rates were 27.3% and 9.1%, respectively. Median gestational age at delivery was 35 weeks (range 34-36). All patients had live births delivered by cesarean section. Obstetric pathology: pre-term labor, placenta percreta or intra-uterine growth restriction, was documented in seven patients (21.2%). Two (6.1%) neonates had low birth weight. Definitive treatment was primary chemo-radiation in 19 (57.6%) patients, radical hysterectomy in 11 (33.3%), abandoned radical hysterectomy with para-aortic lymphadenectomy and ovarian transposition in 1 patient (3.0%), and no further treatment in 2 (6.1%) patients. After a median follow-up of 16.3 months (range 2.0-36.9), 8 (26.7%) patients had recurrent disease. Of these, four (13.3%) died due to disease. CONCLUSION: Neoadjuvant chemotherapy may be offered to patients wishing to preserve an ongoing pregnancy in order to achieve fetal maturity. Long-term consequences of chemotherapy in the child are yet to be determined.

OBJECTIVE: The aim of the study was to evaluate the surgical management and the role of different prognostic factors on survival outcomes of women affected by genital (i.e., vulvar and vaginal) melanoma. MATERIALS AND METHODS: Data of patients undergoing primary surgical treatment for genital melanoma were evaluated in this retrospective study. Baseline, pathological, and postoperative variables were tested to identify prognostic factors. Five-year disease-free survival (DFS) and overall survival (OS) were analyzed using Kaplan-Meier and Cox proportional hazards models. RESULTS: Overall, 98 patients met the inclusion criteria. Sixty-seven (68%) and 31 (32%) patients in this study population were diagnosed with vulvar and vaginal melanoma, respectively. Median (range) DFS and OS were 12 (1-70) and 22 (1-70) months, respectively. Considering factors influencing DFS, we observed that at multivariate analysis, only vaginal localization (hazard ratio [HR] = 3.72; 95% CI = 1.05-13.2) and number of mitoses (HR = 1.24; 95% CI = 1.11-1.39) proved to be associated with worse DFS. Nodal status was the only independent factor influencing 5-year OS in patients with vulvar (HR = 1.76; 95% CI = 1.22-2.54; p = .002) and vaginal (HR = 3.65; 95% CI = 1.08-12.3; p = .03) melanoma. CONCLUSIONS: Genital melanomas are characterized by a poor prognosis. Number of mitoses and lymph node status are the main factors influencing survival. Surgery is the mainstay of treatment. A correct and prompt diagnosis is paramount.

Objective: To report the first uterine transposition for fertility preservation in a patient with vulvar cancer.Case: A 26-year-old nulliparous patient with stage IIIB vulvar cancer, which was resected with adequate margins and bilateral inguinofemoral lymphadenectomy.Laparoscopic transposition of the uterus to the upper abdomen, outside of the scope of radiation was performed to preserve fertility and ovarian function. After the end of radiotherapy, the uterus was repositioned into the pelvis.Main Outcome Measure: Uterine and ovarian function preservation. Result: The patient recovered her menstrual cycles spontaneously 1 month after the reimplantation and exhibited normal variation in ovarian hormones.Twelve months after the surgery, the uterus was normal and there was no sign of recurrent disease. Conclusion: Uterine transposition might represent a valid option for fertility preservation in women who require pelvic radiotherapy. However, studies that assess its viability, effectiveness, and safety are required.
RESUMO
OBJECTIVE: To determine the acceptance rate of treatment alternatives for women with either preinvasive conditions or gynecologic cancers during the COVID-19 pandemic among Latin American gynecological cancer specialists. METHODS: Twelve experts in gynecological cancer designed an electronic survey, according to recommendations from international societies, using an online platform. The survey included 22 questions on five topics: consultation care, preinvasive cervical pathology, and cervical, ovarian, and endometrial cancer. The questionnaire was distributed to 1052 specialists in 14 Latin American countries. A descriptive analysis was carried out using statistical software. RESULTS: A total of 610 responses were received, for an overall response rate of 58.0%. Respondents favored offering teleconsultation as triage for post-cancer treatment follow-up (94.6%), neoadjuvant chemotherapy in advanced stage epithelial ovarian cancer (95.6%), and total hysterectomy with bilateral salpingo-oophorectomy and defining adjuvant treatment with histopathological features in early stage endometrial cancer (85.4%). Other questions showed agreement rates of over 64%, except for review of pathology results in person and use of upfront concurrent chemoradiation for early stage cervical cancer (disagreement 56.4% and 58.9%, respectively). CONCLUSION: Latin American specialists accepted some alternative management strategies for gynecological cancer care during the COVID-19 pandemic, which may reflect the region's particularities. The COVID-19 pandemic led Latin American specialists to accept alternative management strategies for gynecological cancer care, especially regarding surgical decisions.

OBJECTIVE: To evaluate efficacy and outcomes of the autologous transobturator midurethral sling for treatment of stress urinary incontinence (SUI). METHODS: In a prospective cohort study, an autologous transobturator mid-urethral sling was used to treat SUI among women attending a university hospital in Montevideo, Uruguay, from June 2017 to July 2018. In the first phase, autologous tissue of the abdominis rectus fascia was collected. In the second phase, the midurethral sling was placed via the transobturator approach. Outcomes were measured every 3 months by the International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) Score. Preoperative and postoperative results were compared by Wilcoxon test. RESULTS: Eighteen women with a median age of 51 years were enrolled. The median follow-up was 9 months (range 6-15 months). Overall, 17 women showed symptomatic improvement after the procedure. In a comparison of preoperative versus postoperative ICIQ-FLUTS questionnaires, improvement in the incontinence subscore was observed at 3 (P<0.001), 6 (P<0.001), and 12 (P=0.008) months. No severe complications were observed. CONCLUSION: Use of an autologous transobturator urethral sling was found to be technically feasible and safe for SUI, with good short-term outcomes. Longer follow up and larger series are needed to validate the procedure.

OBJECTIVE: To assess maternal group B streptococcus (GBS) colonization status and the pharmacokinetic profile of penicillin G in the umbilical cord and amniotic fluid compartment during 4 hours of intrapartum antibiotic prophylaxis (IAP). METHODS: In a prospective study at a hospital in Montevideo, Uruguay, 60 GBS carriers in active labor after a singleton pregnancy of 37 weeks or more were enrolled between April 1, 2011, and April 30, 2012. Intravenous penicillin G was administered via a standard regimen. Rectovaginal samples were obtained before IAP initiation, and 2 and 4 hours after the initial dose. Penicillin G concentrations were measured by high-performance liquid chromatography. Samples were obtained from fetal cord blood in all cases and from amniotic fluid obtained from patients who delivered by cesarean. RESULTS: Among the 60 participants, 43 (72%) had a positive rectovaginal sample before IAP initiation. Of these women, 23 (53%) had negative cultures after 2 hours; after 4 hours, only 5 (12%) remained positive for GBS. The penicillin G concentration in amniotic fluid and cord blood was above the minimum inhibitory concentration (0.12 µg/mL) in all cases. CONCLUSION: Four hours of IAP was needed to reduce the number of women with positive GBS cultures to 12%. Therefore, 4 hours of IAP might be necessary to achieve overall effectiveness from this treatment.

OBJECTIVE: The therapeutic outcomes of patients with advanced vulvar cancer are poor. Multi-modality treatments including concurrent chemoradiation or different regimens of neoadjuvant chemotherapy (NACT), and surgery have been explored to reduce the extent of surgery and morbidity. The present single-institution trial aimed to evaluate the efficacy and toxicity of paclitaxel and cisplatin in locally advanced vulvar cancer. METHODS: From 2002 to 2009, 10 patients with stage III-IV locally advanced squamous cell carcinoma of the vulva were prospectively treated with 3 courses of paclitaxel-ifosfamide-cisplatin or paclitaxel-cisplatin. Nine of them subsequently underwent radical local excision or radical partial vulvectomy and bilateral inguino-femoral lymphadenectomy. RESULTS: The clinical response rate of all enrolled patients was 80%, whereas the pathological responses included 1 case with complete remission, 2 with persistent carcinoma in situ, and 6 invasive cancer cases with tumor shrinkage of more than 50%. Four patients had positive nodes. Forty percent of patients experienced grade 3-4 bone marrow toxicity, which was successfully managed with granulocyte-colony stimulating factor, even in cases of elderly patients. Median progression-free survival after surgery was 14 months (range, 5 to 44 months). Six of the 7 recurrent cases were local, and 3 of them were treated with salvage surgery while the other 3 received radiation with or without chemotherapy. After a median follow-up period of 40 months (range, 5 to 112 months), 55.5% of patients remained alive with no evidence of disease, including 2 long-term survivors after recurrence at 5 and 9 years. CONCLUSION: Based on the high response rate and manageable toxicity, NACT with paclitaxel and cisplatin with or without ifosfamide followed by surgery could be considered as a therapeutic option for locally advanced vulvar cancer.
RESUMO
OBJECTIVE: To investigate the association between tumor diameter and intratumoral risk factors that might predict the need for full surgical staging among women with endometrial cancer (EC). METHODS: Data from patients with early-stage EC treated at the Istituto Nazionale dei Tumori, Milan, Italy, between January 2004 and December 2012 were retrospectively analyzed. Associations between tumor diameter and tumor grade, myometrial invasion, risk group, lymphovascular space invasion (LVSI), and lower uterine segment (LUS) involvement were assessed by bivariate and multivariate analysis. RESULTS: In total, 181 patients met the inclusion criteria. The tumor diameter was 2cm or less in 110 women (60%). χ(2) analysis showed that tumor grading, myometrial invasion, risk group, and LVSI were significantly associated with tumor size (P<0.001), whereas LUS involvement was marginally associated (P=0.051). By multivariate analysis, LVSI and myometrial invasion had an independent association with tumor size greater than 2cm (P<0.018). CONCLUSION: Tumor size greater than 2cm was significantly and independently associated with LVSI and myometrial invasion among patients with early-stage EC. Given the difficulty of obtaining reliable LVSI data from frozen sections, tumor size might be used as a surrogate at the time of surgery to provide additional information to triage patients for full surgical staging.
