Câncer de colo uterino na gestação / Cervical cancer in pregnancy

PONTOS-CHAVE • A incidência de câncer durante a gestação tem aumentado devido à tendência das mulheres em postergar a gravidez. O câncer de colo de útero é a terceira neoplasia mais comumente diagnosticada durante o período gestacional. • O rastreamento e o diagnóstico devem se dar como nas pacientes não gestantes; a citologia oncótica cervical é o exame obrigatório do pré-natal, e a colposcopia com biópsia pode ser realizada em qualquer período da gestação. • A gestação complicada pelo diagnóstico de um câncer deve sempre ser conduzida em centro de referência e por equipe multidisciplinar. • A interrupção da gestação em situações específicas, para tratamento-padrão, é respaldada por lei. • A quimioterapia neoadjuvante é uma alternativa segura de tratamento durante a gestação, para permitir alcançar a maturidade fetal. Apresenta altas taxas de resposta, sendo relatada progressão neoplásica durante a gestação em apenas 2,9% dos casos. O risco de malformações fetais decorrentes da quimioterapia é semelhante ao da população geral. Contudo, a quimioterapia está associada a restrição de crescimento intraútero, baixo peso ao nascer e mielotoxicidade neonatal. • Na ausência de progressão de doença, deve-se levar a gestação até o termo.

Principais implicações terapêuticas à qualidade de vida de pacientes com câncer de colo uterino: uma revisão narrativa / Therapeutic implications to the quality of life of cervical cancer's patients: a narrative review

O câncer de colo uterino é o quarto tipo mais incidente e fatal entre as mulheres no Brasil e no mundo, o que representa mundialmente em torno de 600 mil novos casos e mais de 300 mil mortes a cada ano. Assim como o diagnóstico, o tratamento da doença pode impactar de forma significativa a qualidade de vida dessas pacientes. A aplicação de questionários que avaliem os diferentes aspectos da qualidade de vida das mulheres afetadas por esse câncer é uma ferramenta relevante, pois auxilia na compreensão e identificação dos principais danos relacionados ao tratamento. Este trabalho visa analisar a literatura atual que investiga e relata os principais efeitos à qualidade de vida de mulheres com câncer de colo uterino associados a diferentes modalidades terapêuticas e, desse modo, contribuir nas escolhas de tratamento e manejo clínico que resultem em menores impactos à qualidade de vida dessas mulheres.(AU)

Cervical cancer is the fourth most incident and fatal cancer type among women in Brazil and worldwide. This data represents around 600 thousand new cases worldwide each year and more than 300 thousand lives lost. Both diagnosis and treatment can significantly impact the quality of life of cervical cancer patients. The application of questionnaires that assess the different aspects of the quality of life of women affected by this cancer is a relevant tool, as it helps to understand and identify the main damages related to the treatment. This article aims to analyze the current literature that reports the main effects on the quality of life of women with cervical cancer associated with different therapeutic modalities. In this way, the review could assist in the treatment choices that imply less impact on the quality of life of these women.(AU)

Mioma en remanente cervical tras histerectomía supracervical laparoscópica, presentación de un caso y revisión de la literatura / Myoma in cervical remnant after laparoscopic supracervical hysterectomy, case report and literature review

INTRODUCCIÓN: Los leiomiomas uterinos son el tumor pélvico más frecuente en la mujer, derivan de las células musculares lisas del miometrio y pueden localizarse en cualquiera de las porciones uterinas. Se clasifican según su relación con las diferentes capas del útero mediante la clasificación de la FIGO. Pueden ser asintomáticos o producir síntomas como sangrado, problemas reproductivos o dolor por compresión de estructuras vecinas. El tratamiento puede ser médico o quirúrgico, teniendo dentro de este último grupo, la posibilidad de realizar una miomectomía o una histerectomía total o subtotal. La histerectomía subtotal permite mantener el cérvix uterino, de tal forma que la técnica quirúrgica es más sencilla, sin embargo, requiere de la morcelación de la pieza para su extracción; mientras que la histerectomía total elimina el riesgo de recidiva de la patología uterocervical, aunque precisa de una mayor curva de aprendizaje. CASO CLÍNICO: Presentamos el caso de una paciente de 52 años a la que se le realizó una histerectomía supracervical laparoscópica por miomas. Posteriormente, se objetivó la aparición de un nuevo mioma en el remanente cervical, que requirió de una traquelectomía vía vaginal. CONCLUSIÓN: La histerectomía subtotal laparoscópica en úteros con múltiples miomas puede tener como efecto adverso la recidiva miomatosa en el cérvix o la aparición de miomas parasitarios secundarios a la morcelación uterina no estanca. Además, implica continuar con el cribado para la prevención del cáncer de cérvix uterino.

BACKGROUND: Uterine leiomyomas are the most frequent pelvic tumor in women. They derive from smooth muscle cells of the myometrium and can be in any of the uterine parts. They are classified according to their relationship with the different layers of the uterus by the FIGO classification. Uterine leiomyomas can be asymptomatic or produce symptoms such as compression pain, reproductive problems and metrorrhagia. The treatment can be medical or surgical. Within this last group there is the possibility of performing a myomectomy or a total or subtotal hysterectomy. The subtotal hysterectomy allows the uterine cervix to be maintained and therefore the surgical technique is simpler. However, it requires the morcellation of the piece for its removal. Alternatively, total hysterectomy eliminates the risk of recurrence of uterocervical pathology, but this procedure presents a steeper learning curve. CLINICAL CASE: We present the case of a patient of 52 years who underwent a laparoscopic supracervical hysterectomy for myomas. Subsequently, the appearance of a new myoma in the cervical remnant was observed, which required a vaginal trachelectomy. CONCLUSION: Laparoscopic subtotal hysterectomy in myomatous uterus can have as an adverse effect myomatous recurrence in the cervix or the appearance of parasitic myomas secondary to non-contained uterine morcellation. In addition, it involves continuing screening for the prevention of cervical cancer.

Robot-assisted surgery in gynecology

The development of robotic technology has facilitated the application of minimally invasive techniques for complex gynecologic surgery. Robot-assisted gynecologic surgery has grown exponentially since receiving Food and Drug Administration approval for use in gynecologic surgery in 2005. Robotic surgery has several major advantages, including three-dimensional visual magnification, articulation beyond normal manipulation, and the filtering of the operator's hand tremors. Therefore, robotic surgery is suitable for microsurgery, and it could be an alternative option for laparotomy. Robotic surgery has advantages, especially for suture-intensive operations such as myomectomy. Patients who underwent robot-assisted laparoscopic myomectomy had significantly decreased estimated blood loss, complication rates, and length of hospital stay. The advantages of robotic surgery help to overcome the limitations of laparoscopy, especially for complicated procedures in deep infiltrating endometriosis. Although extensive radical operations for deep infiltrating endometriosis of the bowel and urinary tract, such as segmental resections of the bladder, ureters, and bowel, were performed by laparotomy in the past, they are now performed more easily and more effectively using robotic techniques. In a recent systematic review and meta-analysis, robotic and laparoscopic sacrocolpopexy resulted in similar clinical outcomes, but robotic surgery was associated with a longer operation time and higher costs. Robotic and conventional laparoscopic hysterectomy show equivalent surgical and clinical outcomes. Compared to laparotomy, robotic gynecologic cancer surgery results in improved clinical outcomes and comparable oncologic outcomes. If robotic surgery is tailored in terms of patient selection, surgeon ability, and equipment availability, it could be a feasible option for highly advanced minimally invasive surgery.

Tailoring radicality in early cervical cancer: how far can we go? / 부인종양

Today, the patient who is diagnosed with early cervical cancer is offered a variety of treatments apart from standard therapy. Patients can be treated with a less radical hysterectomy (RH) regarding parametrectomy, a trachelectomy either vaginal or abdominal, and this can be performed through a minimal invasive or open procedure. All this in combination with nerve sparing and/or sentinel node technique. Level 1 evidence for the oncological safety of all these modifications is only available from 3 randomized controlled trials (RCTs). Two RCTs on more or less radical parametrectomy both showed that oncological safety was not compromised by doing less radical surgery. Because of the heterogeneity of the patient population and the high frequency of adjuvant radiotherapy, the true impact of surgical radicality cannot be assessed. Regarding the issue of oncological safety of fertility sparing treatments, case-control and retrospective case series suggest that trachelectomy is safe as long as the tumor diameter does not exceed 2 cm. Recently, both a RCT and 2 case-control studies showed a survival benefit for open surgery compared to minimally invasive surgery, whereas many previous case-control and retrospective case series on this subject did not show impaired oncological safety. In a case-control study the survival benefit for open surgery was restricted to the group of patients with a tumor diameter more than 2 cm. Although modifications of the traditional open RH seem safe for tumors with a diameter less than 2 cm, ongoing prospective RCTs and observational studies should give the final answer.

Reproductive counseling and pregnancy outcomes after radical trachelectomy for early stage cervical cancer / 부인종양

OBJECTIVE: To evaluate patient perceptions of preoperative reproductive counseling and to evaluate complications and pregnancy outcomes in women who had radical trachelectomy (RT) for early stage cervical cancer. METHODS: Patients who underwent RT from January 1, 2004, through July 31, 2017, and had been cancer free for more than 1 year after RT were eligible; consented patients were sent a 16-item online survey. RESULTS: Of the 58 eligible patients, 39 patients (67%) completed the questionnaire. Eighteen patients (46%) reported receiving reproductive counseling and 26 (68%) reported receiving counseling about pregnancy risks and complications prior to RT, mainly delivered by gynecologic oncologists. Twenty-nine patients (74%) reported having a complication after RT, and cervical stenosis was the most common complication, occurring in 13 patients (33%). Twenty-four patients actively attempted to conceive after RT, and 20 pregnancies were achieved in 13 patients for a pregnancy rate of 54%. Eight pregnancies were spontaneous and 12 required a fertility treatment. There were 5 spontaneous first-trimester miscarriages; 14 of the 20 pregnancies (70%) resulted in live births. The median time to conception was 13.5 months (range, 1–120). CONCLUSION: A significant proportion of women with early stage cervical cancer do not receive adequate reproductive counseling before RT, and many women undergoing RT experience complications that can negatively impact their fertility. We recommend a preoperative consultation with a reproductive endocrinologist for all patients considering RT.

A Case of Successful Spontaneous Pregnancy after Laparoscopic Radical Trachelectomy with Trans-Abdominal Cervicoisthmic Cerclage Treatment

Women in the reproductive age group diagnosed with cervical cancer can receive radical trachelectomy for fertility preservation. Extremely short cervix following radical trachelectomy could result in cervical incompetence. Although prophylactic cervicoisthmic cerclage is placed at the time of radical trachelectomy, it might not be sufficient to prolong pregnancy. We present a successful term pregnancy after laparoscopic radical trachelectomy and concurrent cervicoisthmic cerclage for early stage cervical cancer.

Terapéutica del cáncer de cuello uterino, una revisión de la literatura / Cervical cancer therapeutics: a literature review / Terapêutica do câncer de colo do útero, uma revisão de literatura

Introducción. El cáncer de cuello uterino es la segunda causa de muerte más frecuente mundialmente; por ello, existen terapias tanto invasivas como poco invasivas que buscan impactar la supervivencia de la enfermedad. Entre los diferentes métodos de tratamiento se encuentran la radioterapia externa, la braquiterapia, la quimioterapia, la conización, la traquelectomía y la histerectomía radical. Objetivo. Revisar las características de cada uno de los métodos de tratamiento disponibles para el manejo del cáncer de cuello uterino. Metodología. Se realizó una búsqueda, en las bases de datos PUBMED y LILACS, de artículos publicados entre los años 2013 y 2016 que tuvieran como tema central el cáncer de cuello uterino y su tratamiento; luego de aplicar criterios de inclusión y exclusión, se seleccionaron 41 artículos para la revisión. Resultados. Para el manejo del cáncer de cérvix se plantean, como métodos poco invasivos: la conización, con supervivencia a cinco años de 95.1% en cáncer microinvasor; la radioterapia de haz externo, con supervivencia total de 92.2% a cinco años; la quimioterapia, con supervivencia similar a la radioterapia, pero con disminución de la necesidad de cirugía; y la braquiterapia combinada con quimioterapia, que logró respuesta en 64% de pacientes con cáncer estadio IA, IIA y IB. En relación con métodos más invasivos, se encuentran la traquelectomía en cáncer temprano sin compromiso local o a distancia, alcanza supervivencia del 95%, con tasas de embarazo de 50% posteriores al tratamiento y la histerectomía radical, con supervivencia total de 100% a cinco años en cáncer estadio IA2 y IB1, requiriendo algunas veces combinación con otros métodos. Para las técnicas quirúrgicas se han desarrollado nuevos abordajes y variantes. Conclusiones. Los tratamientos en cáncer de cérvix han mostrado resultados alentadores en cuanto a supervivencia, además, la conización y traquelectomía permiten preservar la fertilidad. La quimioterapia, la radioterapia de haz externo y la braquiterapia logran buen control del cáncer de cérvix en estadios tempranos y se pueden usar como coadyuvantes de los métodos quirúrgicos. Sin embargo, la histerectomía radical es el estándar esencial para manejo del cáncer de cérvix, con buenos resultados en supervivencia; sus variantes, además, han logrado disminuir las complicaciones.

Introduction. Worldwide, cervical cancer is the second most frequent cause of death, and because of its existence, there are several kinds of therapies that range between invasive to non-invasive ones. The purpose of these procedures is to impact disease survival within the human body. Thus, among those treatment methods used for cervical cancer treatment, we can find the following: external beam radiotherapy, brachytherapy, chemotherapy, cervical conization, trachelectomy, and radical hysterectomy. Objective. To review the characteristics of each one of the available methods for treating cervical cancer. Methodology. Published articles between 2013 and 2016 were collected using the databases PUBMED and LILACS. These articles had as a central topic cervical cancer and its treatment. After applying certain inclusion and exclusion criteria within the research, 41 articles were selected to be reviewed. Results. As non-invasive treatment methods for cervical cancer, the following are proposed: cervical conization method, which has a 5-year survival rate of 95.1% when treating micro-invasive cancer; external beam radiotherapy method, which has an overall 5-year survival rate of 92.2%; chemotherapy method, whose survival rate is similar to external beam radiotherapy method's one, but with a slight diminishing of surgery risk; and finally brachytherapy method, which combined with chemotherapy method achieves 64% of response among patients in cancer stages IA, IIA and IB. On the other hand, more invasive treatment methods are presented as follows: trachelectomy method when treating early cancer stages (with no local involvement or distant spreading) reaches a survival rate of 95% and a post-treatment pregnancy rate of 50%, and radical hysterectomy method has a 5-year survival rate of 100% among patients in cancer stage IA2 and IB1, in spite in some occasions this method requires to be combined with other treatment techniques. New therapeutic approaches and variations have been developed for surgical techniques. Conclusions.Cervical Cancer treatments have shown promising results regarding survival rate and in some procedures, such as conization and trachelectomy, preservation of fertility rate. Methods such as chemotherapy, external beam radiotherapy, and brachytherapy have a great control of cervical cancer in early stages, and they can also be used as adjuvant therapies for surgical interventions. Nonetheless, radical hysterectomy is the standard and essential medical procedure for managing cervical cancer. This method has shown good results regarding survival rates and its variants have helped to diminish associated complications. [Suárez-Cadena FC.Cervical cancer therapeutics: a literature review.

Surgical and obstetrical outcomes after laparoscopic radical trachelectomy and pelvic lymphadenectomy for early cervical cancer

OBJECTIVE: The aim of this study was to evaluate the surgical and obstetrical outcomes of patients with early cervical cancer who underwent laparoscopic radical trachelectomy and pelvic lymphadenectomy. METHODS: We analyzed data from women who underwent laparoscopic radical trachelectomy and pelvic lymphadenectomy between July 2000 and October 2014. RESULTS: Of a total of 12 patients, 91.7% were FIGO (International Federation of Gynecology and Obstetrics) stages IA2 and IB1. Seven patients (58.3%) had squamous cell carcinoma. The median tumor size was 1.87 cm (range, focal to 4.6 cm) and two patients (16.7%) had a tumor lager than 2 cm. Lymphovascular space invasion in the tumor lesion was reported in six patients (50%). The following surgical complications were observed: neurogenic bladder (one patient), hemoperitoneum (one patient), and infection (one patient). A total of 33.3% had attempted to conceive, resulting in two pregnancies and two healthy babies. All pregnancies were achieved by in vitro fertilization and embryo transfer. Each woman underwent cesarean delivery because of premature pre-labor rupture of membranes at gestational weeks 27.3 and 33.3. After a median follow-up time of 4.4 years (range, 1 to 8 years), there were no recurrences or deaths. CONCLUSION: Laparoscopic radical trachelectomy and pelvic lymphadenectomy should be offered as an alternative treatment for women with early stage cervical cancer who want to preserve their fertility.
