Machine Learning Quantification of Intraepithelial Tumor-Infiltrating Lymphocytes as a Significant Prognostic Factor in High-Grade Serous Ovarian Carcinomas.

The prognostic and predictive role of tumor-infiltrating lymphocytes (TILs) has been demonstrated in various neoplasms. The few publications that have addressed this topic in high-grade serous ovarian carcinoma (HGSOC) have approached TIL quantification from a semiquantitative standpoint. Clinical correlation studies, therefore, need to be conducted based on more accurate TIL quantification. We created a machine learning system based on H&E-stained sections using 76 molecularly and clinically well-characterized advanced HGSOC. This system enabled immune cell classification. These immune parameters were subsequently correlated with overall survival (OS) and progression-free survival (PFI). An intense colonization of the tumor cords by TILs was associated with a better prognosis. Moreover, the multivariate analysis showed that the intraephitelial (ie) TILs concentration was an independent and favorable prognostic factor both for OS (p = 0.02) and PFI (p = 0.001). A synergistic effect between complete surgical cytoreduction and high levels of ieTILs was evidenced, both in terms of OS (p = 0.0005) and PFI (p = 0.0008). We consider that digital analysis with machine learning provided a more accurate TIL quantification in HGSOC. It has been demonstrated that ieTILs quantification in H&E-stained slides is an independent prognostic parameter. It is possible that intraepithelial TIL quantification could help identify candidate patients for immunotherapy.

Cáncer de endometrio: tratamiento quirúrgico en un hospital comunitario de España / Endometrial cancer: surgical treatment in a community hospital in Spain

Resumen OBJETIVO: Exponer los desenlaces quirúrgicos de las pacientes intervenidas por cáncer de endometrio, analizar si existen puntos de mejora en nuestra práctica clínica y aportar más datos a la evidencia publicada, para ayudar al avance en el tratamiento quirúrgico de las pacientes con esta enfermedad MATERIALES Y MÉTODOS: Estudio observacional, descriptivo y retrospectivo llevado a cabo en la Unidad de Oncología Ginecológica del Hospital Regional Virgen Macarena de Sevilla, España, entre junio de 2013 y febrero de 2020. Se reunieron los reportes quirúrgicos de pacientes intervenidas por alguna afección endometrial premaligna o maligna. Variables de estudio: edad, IMC, cirugías previas, diagnóstico histopatológico y estadio, vía de acceso quirúrgico y terapia coadyuvante. Se exponen los desenlaces relacionados con complicaciones quirúrgicas y tasa de curación, así como el tiempo de intervención, vía de acceso quirúrgico y estancia hospitalaria. RESULTADOS: Se estudiaron 250 pacientes, la mayoría (76%) con diagnóstico de adenocarcinoma endometrioide de endometrio. La vía de acceso quirúrgico más utilizada fue la laparoscopia (51.6%), con un porcentaje de complicaciones intraoperatorias del 10% y posoperatorias del 9.2%. El 88.4% de las pacientes permanece viva y libre de enfermedad después del tratamiento, con recaídas solo en el 11.6% y 8% de fallecimientos. CONCLUSIONES: El tratamiento inicial de elección, en pacientes con hiperplasia con atipias o cáncer de endometrio en estadios tempranos, es la cirugía, mediante histerectomía, doble anexectomía y en algunos casos linfadenectomía asociada. La elección de la vía quirúrgica de acceso debe individualizarse a las condiciones particulares de cada paciente. La laparoscopia ofrece múltiples ventajas, es una técnica en auge y cada día más practicada.

Abstract OBJECTIVE: To expose the surgical outcomes of patients operated on for endometrial cancer, to analyze if there are points of improvement in our clinical practice and to contribute more data to the published evidence, to help advance the surgical treatment of patients with this disease. MATERIALS AND METHODS: Observational, descriptive, and retrospective study carried out in the Gynecologic Oncology Unit of the Virgen Macarena Regional Hospital of Seville, Spain, between June 2013 and February 2020. Surgical reports of patients operated on for any premalignant or malignant endometrial condition were collected. Study variables: age, BMI, previous surgeries, histopathological diagnosis and stage, surgical access route and adjuvant therapy. Outcomes related to surgical complications and cure rate are presented, as well as operation time, surgical access route and hospital stay. RESULTS: 250 patients were studied, the majority (76%) with a diagnosis of endometrioid endometrial adenocarcinoma. The most used surgical access route was laparoscopy (51.6%), with a percentage of intraoperative complications of 10% and postoperative complications of 9.2%. 88.4% of patients remain alive free of disease after treatment, with relapses in only 11.6% and 8% deaths. CONCLUSIONS: The initial treatment of choice in patients with hyperplasia with atypia or early-stage endometrial cancer is surgery, by hysterectomy, double adnexectomy and in some cases associated lymphadenectomy. The choice of surgical approach must be individualized to the conditions of each patient. Laparoscopy offers multiple advantages; it is a technique that is on the rise and is being used more and more frequently.

Adenosarcoma de alto grado de endocérvix y cavidad endometrial con componente heterólogo de rabdomiosarcoma. Reporte de caso y revisión de la literatura / High grade adenosarcoma of endocervix and endometrial cavity with a heterologous component of rhabdomyosarcoma. Case report and review of the literature

Objective: To present the case of a patient diagnosed with high grade adenosarcoma of the endocervix and the endometrial cavity, with a heterologous component, and to conduct a review of the literature focusing on the diagnosis and therapeutic management of this disease condition. Materials and methods: We present the case of a 31-year-old female patient who came to Virgen Macarena University Hospital of Seville, a Level III regional institution, complaining of genital bleeding arising from an endocervical polypoid mass. The biopsy of the mass revealed a high grade, poorly differentiated leiomyosarcoma of the endocervix. The patient was taken later to total abdominal hysterectomy. The study of the surgical specimen provided the following result: adenosarcoma of the endocervix and endometrial cavity with a heterologous rhabdomyosarcoma component. A search was conducted in the Medline database via Pubmed using the terms "adenosarcoma," "endocervical," "cervix," "uterus," "heterologous." The search in- cluded literature review articles, case reports and clinical case series describing aspects of cervical adenosarcoma and the heterologous rhabdomyosar- coma component, published in English and Spanish since 1974. Results: Six articles corresponding to literature reviews, case reports or case series in which the most relevant aspects of the diagnosis and treatment of this disease condition are described were retrieved. Conclusions: This condition is characterized, on occasions, by rapid and aggresive growth, hence the importance of early diagnosis and optimal treatment based on a combination of surgery, radiation therapy and chemotherapy. However, due to its low prevalence, further studies are needed in order to confirm these data.

Objetivo: presentar el caso de una paciente con diagnóstico de adenosarcoma de alto grado de en- docérvix y de cavidad endometrial, con componente heterólogo, y hacer una revisión de la literatura con especial atención al diagnóstico y manejo terapéutico de esa patología. Materiales y métodos: Se presenta el caso de una paciente de 31 años, que consulta al Hospital Universitario Virgen Macarena de Sevilla, institución regional de tercer nivel, por presentar san grado genital originado por una masa polipoidea endocervical que se llevó a biopsia con resultado de un leiomiosarcoma poco diferenciado de alto grado de endocérvix. Posteriormente fue llevada a histerectomía total abdominal. En el estudio de la pieza quirúrgica el resultado fue: adenosarcoma de endocérvix y cavidad endometrial, con componente heterólogo de rabdomiosarcoma. Con los términos: "adenosarcoma", "endocervical", "cérvix", "uterus", "heterologous", en las bases de datos Medline vía PubMed se realizó una búsqueda de artículos de revisión bibliográfica, reportes y series de casos clínicos que describían aspectos del adenosarcoma cervicouterino y del componente heterólogo de rabdomiosarcoma, en inglés y español, publicados desde 1974. Resultados: se hallaron seis artículos correspondientes a revisiones de la literatura, reportes o series de casos, donde se describen los aspectos más importantes referentes al diagnóstico y tratamiento de esta patología. Conclusiones: esta patología se caracteriza, en ocasiones, por un crecimiento rápido y agresivo, donde es importante el diagnóstico precoz y el tratamiento óptimo, basado en una combinación de cirugía, radioterapia y quimioterapia, aunque dada su baja prevalencia se necesitan aún más estudios para poder confirmar estos datos.

Direct trocar insertion without previous pneumoperitoneum versus insertion after insufflation with Veress needle in laparoscopic gynecological surgery: a prospective cohort study.

The aim of this study was to determine whether direct trocar entry without prior pneumoperitoneum at umbilical level (DTI) can be a safe alternative to access the abdominal cavity in gynaecological laparoscopic surgery. We present a prospective observational analytical study of cohorts, comparing DTI with umbilical entry with trocar after previous insufflation with a Veress needle at umbilical level (V). The study period was performed from June 2013 to April 2016; data was collected on 600 patients who underwent gynaecological laparoscopic surgery. There were no significant differences in the risk of suffering a complication during the access manoeuvres between DTI (6.49%) and V (7.39%), OR 0.89 (95% CI: 0.42-1.81). The duration of the access manoeuvres was 69 s in DTI and 193 s in V (p < .001). The percentage of patients in whom two or more access attempts were performed was lower in DTI (7.8%) than in V (12.3%) (p > .05). We concluded that DTI is at least as safe as V, regarding the risk of suffering complications arising from access into the abdominal cavity. DTI has advantages with regard to V, such as: the shorter duration of access manoeuvres or the lesser number of unsuccessful entry or insufflation attempts. Impact statement What is already known on this subject? There are few international publications comparing DTI and V. When we conducted a search in PubMed for the terms 'Veress needle and direct trocar insertion', 51 publications were obtained. When we increased the restriction and added the terms 'laparoscopic entry and laparoscopy complications', 27 publications were obtained; thus, the uniqueness of our study. What do the results of this study add? We present a 3-year observational prospective study of cohorts that included 600 patients. The aim of this study was to determine that in laparoscopic gynaecological surgery, DTI is an access method to the abdominal cavity at least as safe as V, with respect to the risk of complications. On the other hand, DTI has some advantages such as the shorter duration of access manoeuvres or the lower number of failed entry attempts. What are the implications of these findings for clinical practice and/or further research? Given the limited number of publications that compared both techniques, our study indicates that DTI can be a safe alternative for access to abdominal cavity in gynaecological surgery, compared to the traditional V.

Carcinoma de ovario en paciente con mutación del gen BRCA1. Diagnóstico tras biopsia de adenopatía cervical, en el contexto de un síndrome paraneoplásico cutáneo / Ovarian carcinoma in a patient with a BRCA1 gene mutation. Diagnosis after biopsy of cervical adenopathy, in the context of a cutaneous paraneoplastic syndrome

RESUMEN El cáncer epitelial de ovario representa uno de los tumores ginecológicos más letales ya que más del 75% de las pacientes son diagnosticadas en estadío avanzado. Aún no se ha demostrado que la realización de pruebas y exámenes pélvicos rutinarios haya reducido la mortalidad, no existiendo actualmente, un cribado eficaz para su diagnóstico precoz. Aunque la sintomatología metastásica extraperitoneal más común es el derrame pleural, las linfadenopatías neoplásicas a nivel supraclavicular aparecen hasta en el 4% de casos, generalmente asociándose a un mal pronóstico. La identificación de una adenopatía supraclavicular se relaciona hasta en un 58-83% de los casos, con el hallazgo de una tumoración maligna. Por otro lado, la dermatomiositis del adulto puede tener un origen paraneoplásico en un 15-25% de las ocasiones, siendo el cáncer de mama y de ovario la etiología más frecuente en la población femenina. Las pacientes portadoras de mutaciones en los genes BRCA 1 y 2 tienen un aumento del riesgo de padecer neoplasias de mama y ovario. En aquellas afectas de un cáncer de ovario y portadoras de una mutación en los genes BRCA, no se debería plantear una cirugía profiláctica de rutina sobre la mama, al menos en los primeros 5 años tras el diagnóstico de la neoplasia ovárica. Presentamos el caso de una paciente portadora de una mutación germinal del gen BRCA 1, que debuta con un cáncer de ovario, tras el estudio de una adenopatía neoplásica de cuello, biopsiada en el contexto de un síndrome paraneoplásico cutáneo.

ABSTRACT Epithelial ovarian cancer represents one of the most lethal gynecological tumors, since more than 75% of affected women are diagnosed at an advanced stage. However, studies have not demonstrated yet that performing routine pelvic exams and tests had reduced mortality in ovarian cancer, and currently there is no effective screening for early diagnosis. The most common extraperitoneal metastatic symptomatology of ovarian cancer is pleural effusion, but there are other, like neoplastic lymphadenopathies at supraclavicular level, described in up to 4% of cases and generally related to a poor prognosis. The identification of a supraclavicular adenopathy is associated with the finding of a malignant tumor in 58-83% of the cases. On the other hand, adult dermatomyositis can have a paraneoplastic origin in 15-25% of patients, being breast and ovarian cancer the most frequent etiology in the female population. Patients with BRCA 1 and 2 genes mutations have an increased risk of breast and ovarian malignancies. In those affected by an ovarian cancer and carriers of a mutation in the BRCA genes, routine prophylactic surgery should not be considered on the breast, at least in the first 5 years after the diagnosis of ovarian neoplasia. We present the case of a patient with a germinal mutation of the BRCA 1 gene, who debuts with an ovarian cancer, after the study of a neoplastic adenopathy of neck, biopsied in the context of a cutaneous paraneoplastic syndrome.

Adenocarcinoma sincrónico de alto grado de endometrio y ovario; a propósito de un caso clínico / Synchronous high-grade adenocarcinoma of the endometrium and ovary; about a clinical case

RESUMEN El cáncer sincrónico endometrial y ovárico (SEOC) representa alrededor de un 5-10% de las neoplasias de endometrio y ovario. Cuando no existe extensión locorregional y presentan un patrón histológico de bajo grado, actúan como si fueran dos tumores primarios independientes, en lugar de comportarse como un cáncer en estadio avanzado. Los mecanismos para diferenciar si su origen es metastásico o por el contrario, son tumores primarios independientes conlleva una gran dificultad y ha generado una importante controversia dentro del estudio de este tipo de neoplasias. En este artículo, exponemos el caso clínico de una paciente de 46 años que presenta un tumor sincrónico de endometrio y ovario en estadio IA, desconocido hasta el estudio histológico de la pieza quirúrgica.

ABSTRACT Endometrial and ovarian synchronous cancer (SEOC) accounts for about 5-10% of endometrial and ovarian neoplasms. When there is no local extension and they present a low-grade histological pattern, they act as if they were two independent primary tumours, instead of behaving as an advanced stage cancer. Therefore, the differentiation of its origin (metastatic or independent primary tumours) is fraught with difficulty and has generated a significant controversy in the study of this type of neoplasms. In this article, we present the clinical case of a 46-year-old patient presenting a synchronous tumor of the endometrium and ovary in IA stage, unknown until the histological study of the surgical sample.

Mioma vaginal intraabdominal, masa pélvica de localización atípica / Intra-abdominal vaginal myoma, a pelvic mass of atypical location

La patología miomatosa del tracto genital inferior es uno de los motivos más frecuentes de consulta en Ginecología. Sin embargo, su localización vaginal resulta una situación infrecuente de difícil diagnóstico. En muchas ocasiones se lleva a cabo tras un hallazgo casual intraoperatorio. Las manifestaciones clínicas que producen los leiomiomas en esta localización son inespecíficas; el tratamiento quirúrgico es el de elección, generalmente mediante un abordaje por la vía vaginal(AU)

Myomatous disease of the lower genital tract is one of the most common reasons for gynecological consultation. However, vaginal location is infrequent and difficult to diagnose. On many occasions diagnosis is based on a fortuitous intraoperative finding. The clinical manifestations of vaginal leiomyomas are unspecific. Surgery is the treatment of choice, which is generally performed by vaginal approach(AU)

Adenocarcinoma mucinoso del paraovario: un tumor infrecuente / Mucinous paraovarian adenocarcinoma: a rare tumour

Se denomina tumor del paraovario a aquel que se desarrolla en los tejidos cercanos al ovario. Dado que generalmente no producen manifestaciones clínicas, su diagnóstico se suele realizar de forma incidental durante cirugías, estudios de fertilidad o post-mortem. Aunque la degeneración neoplásica de estas lesiones es altamente infrecuente, cuando ocurre puede dar lugar a tumores tanto de bajo como de alto grado. Presentamos un caso de adenocarcinoma mucinoso del paraovario intervenido en nuestro centro y revisamos la literatura disponible del tema (AU)

Paraovarian tumors are those that arise from tissues surrounding the ovaries. Given that they do not normally cause symptoms, they are usually diagnosed during surgery, fertility studies, or post-mortem. Neoplastic transformation of these lesions is highly infrequent but can give rise to low-grade (borderline) as well as high-grade tumours. We present a case of paraovarian mucinous adenocarcinoma and provide a review of the available literature on the subject (AU)

Metástasis ovárica única de angiosarcoma mamario como localización infrecuente / Single ovarian metastases of breast angiosarcoma as unusual location

Los angiosarcomas son tumores vasculares extremadamente raros con alta tasa de proliferación e invasión. Están caracterizados por células anaplásicas que se originan en las paredes de los vasos sanguíneos. Poseen mal pronóstico debido a su comportamiento altamente agresivo, el cual condiciona una elevada probabilidad de recurrencia local y extensión multiorgánica. Se presentan principalmente en: pulmón, hígado, ganglios linfáticos y huesos. Su tratamiento es controvertido debido escasa casuística disponible acerca de esta estirpe tumoral, aunque parece claro que el tratamiento principal es la cirugía y que el tratamiento posterior puede ser la quimioterapia adyuvante(AU)

Angiosarcomas are extremely rare vascular tumors with high rate of proliferation and invasion. They are characterized by anaplastic cells originating in the walls of blood vessels. They have poor prognosis because of their highly aggressive behavior, which determines a high probability of local recurrence and spreading to multiple organs. They occur mainly in lung, liver, lymph nodes and bones. Treatment is controversial due to small number of cases available about this tumor type, although it seems clear that the main treatment is surgery and subsequent treatment can be adjuvant chemotherapy(AU)

Uso de la traquelectomía radical en cáncer de cérvix con histología infrecuente: a propósito de 2 casos / Use of radical trachelectomy in cervical cancer with rare histology: two case reports

La traquelectomía radical es una intervención que permite preservar la fertilidad en mujeres jóvenes con cáncer de cérvix en estadio precoz. Su seguridad ha sido sobradamente demostrada en el tratamiento de la estirpe escamosa, pero existen dudas sobre la conveniencia de usarla en histologías vinculadas tradicionalmente a un peor pronóstico. Presentamos aquí 2 casos atípicos de cáncer de cérvix (adenocarcinoma de células claras y carcinoma escamoso con adenocarcinoma coexistente) intervenidos mediante traquelectomía radical previa biopsia de ganglio centinela pélvico (AU)

Radical trachelectomy is a surgical technique that allows young women with early invasive cervical carcinoma to preserve their fertility. Although its safety has been demonstrated in squamous histology, doubts remain about the advisability of this intervention in histological types traditionally associated with a worse outcome. We describe two cases of rare cervical tumors (clear cell adenocarcinoma and synchronous invasive squamous cell carcinoma and invasive adenocarcinoma) treated with radical trachelectomy after pelvic sentinel node biopsy (AU)

Entrada laparoscópica directa umbilical con trocar sin neumoperitoneo previo: una alternativa segura / Transumbilical direct trocar entry without prior pneumoperitoneum: a safe alternative

Objetivo. Comparar la entrada directa umbilical con trocar sin neumoperitoneo previo en laparoscopia con el uso de la aguja de Veress. Método. Se revisan las hojas quirúrgicas de 183 pacientes en las que se usó la vía laparoscópica, dividiéndolas en 2 grupos: G1: usando la aguja de Veress, y G2: usando la entrada umbilical del trocar sin neumoperitoneo previo. Se recogieron las complicaciones producidas. Resultados. La edad media era de 40 años y el IMC medio de 29. Solo se registraron 3 casos de enfisema preperitoneal y en todos ellos se usó la aguja de Veress. Conclusión. Según nuestra experiencia, y en concordancia con la literatura, el método de entrada directa umbilical del trocar sin neumoperitoneo previo es un método seguro, sin complicaciones en nuestra serie, presentando ventajas: mayor velocidad de consecución del neumoperitoneo, ausencia de riesgo de embolismo gaseoso, simplificación de los pasos quirúrgicos y menor tasa de fallos en la entrada (AU)

Objective: To compare transumbilical direct trocar entry without prior pneumoperitoneum in laparoscopic surgery with Veress needle insertion. Method: The surgical records of 183 patients who underwent laparoscopy were reviewed. The patients were divided into two groups according to the surgical technique employed: group 1: Veress needle insertion; group 2, transumbilical direct trocar entry without prior pneumoperitoneum. The complications were recorded Results: The mean age was 40 years and the mean body mass index was 29. There were only three cases of preperitoneal emphysema, all occurring in group 1. Conclusion: In our experience, and in agreement with the literature, transumbilical direct trocar entry without prior use of Veress needle is a safe alternative. There were no complications in our series. This alternative offers certain advantages, such as more rapid achievement of the pneumoperitoneum, the absence of risk of gas embolism, simplification of the surgical steps, and lower rate of entry failures (AU)
