Abstract Current online information flows have taken on immeasurable dimensions, thereby influencing the masses, both positively and negatively, thus allowing decision-making and the generation of ways of thinking, which on many occasions turn out to be unfounded and cause misinformation. The analysis is based on the need to generate an epistemic contribution around online information processes for the purposes of classification and general characterization with a special focus on emerging countries (especially Latin American) through documentary research. This proposal identifies the construction of a taxonomy of information evaluation processes, consisting of three general groups: (1) structured ones (coming from formal education and through systematic content that causes explicit learning); (2) unstructured ones (deliberately acquired, through non-formal processes, which generate tacit learning that is not necessarily correct or well-founded); and (3) complementary ones (referring to alternative methodologies for diagnosing misinformation situations). The paper concludes by presenting proposals for various forms of intervention and identifying best practices in order to avoid biases in misinterpretation, especially when the information is false.

Resumen Los flujos actuales de información en línea han tomado dimensiones inmensurables, logrando con ello influir en las masas, tanto de forma positiva como negativa, permitiendo así la toma de decisiones y la generación de formas de pensar, que en diversas ocasiones resultan infundadas y provocan la desinformación. El análisis parte de la necesidad de generar una contribución epistémica en torno a los procesos de información en línea con fines de clasificación y caracterización general con especial enfoque hacia países emergentes (especialmente latinoamericanos) a través de la investigación documental. Esta propuesta identifica la construcción de una taxonomía de procesos de evaluación de la información, constituida en tres grupos generales: (1) los estructurados (provenientes de la educación formal y por medio de contenidos sistemáticos que provocan un aprendizaje explícito); (2) los no estructurados (adquiridos de forma deliberada, por medio de procesos no formales, que generan un aprendizaje tácito que no necesariamente es correcto o fundamentado); y (3) los complementarios (referidos a metodologías alternativas de diagnóstico sobre situaciones de desinformación). Se concluye presentando propuestas de diversas formas de intervención e identificación de mejores prácticas en razón de evitar sesgos en la mala interpretación, especialmente cuando la información es falsa.

RESUMEN Los schwannomas cervicales son tumores encapsulados benignos de la vaina nerviosa que corresponden a menos del 0,1% de los tumores de cabeza y cuello. Suelen presentarse como una tumoración cervical asintomática. Son lesiones cuyo tratamiento de primera línea es la resección quirúrgica. Es fundamental el uso de neuromonitorización durante el procedimiento y realizar una cirugía en conjunto con un especialista en nervios periféricos. En ocasiones resulta dificultoso conservar la funcionalidad del nervio involucrado. Se presenta el caso de una paciente de 27 años que consulta por una tumoración cervical derecha. Se realizaron tomografía computarizada y resonancia magnética nuclear cervical que evidenciaron una imagen sugestiva de schwannoma de neumogástrico. Se realizó la exéresis completa de la lesión con neuromonitorización intraoperatoria. Presentó una disfonía transitoria en posoperatorio.

ABSTRACT Schwannomas are encapsulated benign tumors that arise from the peripheral nerve sheaths and account for 0.1% of head and neck tumors. They usually present as asymptomatic lateral neck masses. Surgical resection is the first-line therapy of these lesions. Intraoperative neuromonitoring is essential, and a neurosurgeon specializing in peripheral nerves needs to participate during surgery. Preservation of nerve functioning is sometimes difficult. We report the case of a 27-year-old female patient sought medical care due to a mass in the right lateral region of the neck. Computed tomography scan and nuclear magnetic resonance imaging suggested the presence of a pneumogastric schawannoma. The tumor was totally resected with intraoperative neuromonitoring. The patient evolved with transient dysphonia.

Resumen Introducción : La región selar es un sitio infrecuente de metástasis, encontrándose en el 1% de las cirugías hipofisarias. Los tumores primarios más habituales son mama y pulmón. En general son diagnosticadas en pa cientes con enfermedad avanzada, aunque pueden ser el debut de la enfermedad oncológica. Métodos : Análisis retrospectivo de las características clínicas, bioquímicas, radiológicas de pacientes con me tástasis selares o hipofisarias (MS) durante el periodo 2009-2020. Resultados : Se reportaron 18 casos de pacientes, 11 de ellos con confirmación histológica. La mediana de edad fue 53 años (rango: 35-75), 53% hombres. La loca lización del tumor primario fue: 8 pulmón, 6 mama, 1 carcinoma folicular de tiroides, 1 linfoma Hodgkin y 2 carcinomas renales de células claras. La media de tiem po entre el diagnóstico del tumor primario y la aparición de la MS -en los casos de presentación metacrónica- fue 108 meses (rango: 11-180). En 8 pacientes (44.4%), el diagnóstico de la neoplasia primaria se hizo a partir del hallazgo de la masa selar. Diabetes insípida, hipopitui tarismo, trastornos visuales, oftalmoplejía y cefalea se presentaron en el 78, 77, 61, 39 y 39%, respectivamente. Quince pacientes presentaron masas con extensión su pra/paraselar; y 3 lesión limitada a la hipófisis y tallo. Fueron operados 11/18 por vía transesfenoidal, para diagnóstico y/o descompresión. Fallecieron 17, con una mediana de sobrevida de 6 meses (1- 36). Discusión : La sospecha de MS debe estar presente ante una masa selar y supraselar con captación difusa del gadolinio, diabetes insípida, hipopituitarismo y/o disfunción visual, aun en pacientes sin antecedentes oncológicos.

Abstract Introduction : Sellar metastases (SM) are rare mani festations of malignancy. Breast and lung cancer are the most common primary tumors. Most cases are di agnosed in patients with advanced malignant disease; however, symptoms of pituitary involvement can pre cede the diagnosis of the primary tumor. Methods : Retrospective analysis of symptoms at presentation, hormonal, radiological and histological findings, management, and outcome of patients with SM from 2009 to 2020. Results : Eighteen patients´cases were included, 11 with histological confirmation. Median (m) age was 53 years (range 35-75), 53% male. Primary malignant tu mors: 8 lungs, 6 breast, 1 follicular thyroid carcinoma, 1 Hodgkin lymphoma, and 2 clear cell renal carcinomas. The m time between the diagnosis of the primary neo plasm and the occurrence of the SM was 108 months (range: 11-180). In 8 patients the diagnosis of the primary neoplasm was made after the finding of the symptom atic sellar mass. Insipidus diabetes, adenohypophysis deficit, visual disorders, headache, and cranial nerve deficits were evident in 78, 77, 61, 39 and 39% of the cases, respectively. Fifteen patients harbored supra / parasellar masses, in three a lesion was limited to the pituitary gland, and stalk. Eleven out of 18 (61.1%) of the patients were operated on by the trans-sphenoidal approach, for diagnostic and / or decompressive pur poses. Eighteen died, with a median survival time of 6 months (1-36). Discussion : In the presence of a pituitary lesion with diffuse gadolinium uptake, associated with insipidus diabetes and / or visual disorder SM should be suspected even in patients without a history of oncological disease.

Abstract Objective: Ovarian torsion (OT) represents a severe gynecological emergency in female pediatric patients, necessitating immediate surgical intervention to prevent ovarian ischemia and preserve fertility. Prompt diagnosis is, therefore, paramount. This retrospective study set out to assess the utility of combined clinical, ultrasound, and laboratory features in diagnosing OT. Methods: The authors included 326 female pediatric patients aged under 14 years who underwent surgical confirmation of OT over a five-year period. Logistic regression analysis was employed to pinpoint factors linked with OT, and the authors compared clinical presentation, laboratory results, and ultrasound characteristics between patients with OT (OT group) and without OT (N-OT group). The authors conducted receiver operating characteristic (ROC) curve analysis to gauge the predictive capacity of the combined features. Results: Among 326, OTwas confirmed in 24.23 % (79 cases) of the patients. The OT group had a higher incidence of prenatal ovarian masses than the N-OT (22 cases versus 7 cases) (p < 0.0001). Similarly, the authors observed significant differences in the presence of lower abdominal pain, suspected torsion on transabdominal ultrasound, and a high neutrophil-lymphocyte ratio (NLR > 3) between the OTand non-OT groups (p < 0.05). Furthermore, when these parameters were combined, the resulting area under the curve (AUC) was 0.868, demonstrating their potential utility in OT diagnosis. Conclusion: This study demonstrates a prediction model integrating clinical, laboratory, and ultrasound findings that can support the preoperative diagnosis of ovarian torsion, thereby enhancing diagnostic precision and improving patient management. Future prospective studies should concentrate on developing clinical predictive models for OTin pediatric patients.

Abstract The selection of promising microorganisms that meet the requirements of a fermentation process is the most important stage in the development of microbiological starters. With the objective of selecting potential strains to be integrated as microbiological starters in cocoa fermentations, which promote biochemical dynamics, improving their sensory quality, the resistance of six yeasts (GRAS), isolated from cocoa fermenting masses in the departments, was evaluated. from Tolima, Huila and Antioquia, two commercial yeasts ATCC 28253 and ATCC 36633 selected for their aromatic production, subjecting them to resistance tests, at different concentrations of soluble solids (10, 15 and 20 °Brix), ethanol (5, 10%), acetic acid (pH 3, 4, 5, 6, and 7) and temperature (30, 40 and 50 °C), which simulated the biochemical dynamics of cocoa fermentation, quantifying its resistance expressed in viable cells. Aromatic production was measured by sensory evaluation. The yeasts Wickerhamomyces anomalus and Pichia kudriavzevii were selected for their ability to transform substrate into products of interest during the fermentation of cocoa pulp, production of specific aromas and resistance to adverse biochemical conditions typical of cocoa fermentation.

ABSTRACT: In order to ensure reliable inferences in scientific experiments, sampling criteria should be determined and defined during the experimental design phase. Determining plot and sample sizes without scientific criteria could result in resource and labor inefficiencies with no gain in experimental precision. In this work we estimate plot and sample sizes for biometric variable analyses in lettuce seedlings. The seedlings were sown in four expanded polystyrene foam transplant trays with 128 and 200 cells. Foliar area, stem diameter, shoot height, root length, root volume, root area, fresh and dry shoot and root masses. The methods described by Paranaiba (PARANAIBA et al., 2009) and Cochran (COCHRAN, 1977) were used for plot size and sample size estimations, respectively. Sample size varied according to the variables analysed and transplant tray cell number. Root variables required the highest number of samples. For a 10% margin of error, 12 seedlings were necessary for evaluations in a 128 cell tray, while 11 seedlings were required for analysis in 200 cell trays.

RESUMO: A fim de garantir inferências confiáveis em experimentos científicos, os critérios de amostragem devem ser determinados e definidos durante a fase de planejamento experimental. Determinar tamanhos de parcelas e amostras sem critérios científicos pode resultar em ineficiências de recursos e mão de obra sem ganho de precisão experimental. Neste trabalho estimamos tamanhos de parcelas e amostras para análises de variáveis biométricas em mudas de alface. As mudas foram semeadas em quatro bandejas de transplante de espuma de poliestireno expandido com 128 e 200 células. Área foliar, diâmetro do caule, altura da parte aérea, comprimento da raiz, volume da raiz, área da raiz, parte aérea fresca e seca e massas radiculares. Os métodos descritos por Paranaíba (PARANAÍBA et al., 2009) e Cochran (COCHRAN, 1977) foram utilizados para estimativas de tamanho de parcela e tamanho de amostra, respectivamente. O tamanho da amostra variou de acordo com as variáveis analisadas e o número de células da bandeja de transplante. As variáveis de raiz exigiram o maior número de amostras. Para uma margem de erro de 10%, foram necessárias 12 mudas para avaliação em bandeja de 128 células, enquanto 11 mudas foram necessárias para análise em bandeja de 200 células.

ABSTRACT Purpose: CT-guided MWA is a safe and effective tool that should be utilized in the treatment of small renal masses (SRMs). We aim to clarify the utility of CT-guided MWA by examining patient outcomes such as recurrence, treatment success, changes in renal function, and complications. Methods: A retrospective review of consecutive patients with SRMs who underwent same day renal mass biopsy (RMB) and CT-guided MWA between 2015 and 2022 was performed. Treatment safety was assessed by 30-day complications according to the Clavien-Dindo system and change in eGFR >30 days post-procedure. Treatment efficacy was defined by local recurrence and incomplete treatment rates and calculated using the Kaplan-Meier method. Results: A total of 108 renal masses were found in 104 patients. The overall complication rate was 7.4% (8/108), of which 4 were major complications (3.7%). For those with renal function available >30 days post ablation, the median eGFR was 47.2 (IQR: 36.0, 57), compared to 52.3 (IQR: 43.7, 61.5) pre-ablation, p<0.0001. 5-year local recurrence free survival was 86%. Among those with biopsy proven malignancy (n= 66), there were five local recurrences (7.54%) occurring at a median of 25.1 months (IQR 19.9, 36.2) and one case (1.5%) of incomplete treatment. Conclusions: As the medical field continues to evolve towards less invasive interventions, MWA offers a valuable tool in the management of renal masses. With low major complication and recurrence rates, our findings support the utility of CT-guided MWA as a tool for treatment of SRMs. Purpose CTguided CT guided .

Abstract Cystic pelvic masses are a frequent finding in different imaging tests. Sometimes, it is difficult to determine its origin, especially in the female sex. However, clinical history and different imaging tests can help in a correct diagnostic approach. Our purpose is to show different differential diagnoses of cystic pelvic lesions of non-gynecological origin studied in our hospital.

Resumen Las masas pélvicas quísticas son un hallazgo frecuente en las diferentes pruebas de imagen. En ocasiones, determinar su origen es dificultoso, sobre todo en el sexo femenino. Sin embargo, la historia clínica y las diferentes pruebas de imagen pueden ayudar a una correcta aproximación diagnóstica. Nuestro propósito es mostrar diferentes diagnósticos diferenciales de lesiones pélvicas quísticas de origen no ginecológico estudiadas en nuestro hospital.

Abstract: In the 1920s Westernization and modernism characterized the cultural life of big Japanese cities, and the cinema quickly became the main entertainment of the urban masses. In this decade studios began to shoot movies following the cinematic techniques and narrative styles of European and American cinema, and increased production of film adaptations of Western literature works popular at that time. This paper focuses on the adaptations of German literature works, specifically of Gerhart Hauptmann plays, produced in Japan during the 1920s. While those films have been lost, stills and reviews of film magazines published at the time of screening have been archived. The study draws on these materials and examines the intertextual and intercultural relations between the films and the literary works. It provides a brief overview on the reception of German literature in Japan, compares the plays and films analysing the permutations in narratological elements, and offers insights on how cultural, political, and social context influenced the directors’ adaptation process.

ABSTRACT: Lymphangiomas are benign hamartomatous tumors of the lymphatic vessels, originating from a sequestration of the lymphatic sac and enlarged by inadequate drainage, lack of communication with the central lymphatic channels or excessive secretion of lining cells. The incidence of these tumors in the lymphatic system is low, with a frequency of 1.2 to 2.8/1000 in children, with no predilection for sex. Three types of lymphangioma can be distinguished in the maxillofacial territory: simple lymphangioma, cavernous lymphangioma, and cystic hygroma or cystic lymphangioma. Clinically, these lesions present as painless, slow-growing soft tissue masses. Their clinical appearance depends on the extent of the lesion. Various treatment methods for lymphangioma have been reported in the literature, with surgical excision being indicated mainly when vital structures are not involved in the lesion. This article presents a case of a 13-year-old female patient with an increase in volume in the vermilion of the upper lip, with a history of Koolen De Vries syndrome, in which the excision of the lesion was performed.

RESUMEN: Los linfangiomas son tumores benignos hamartomatosos de los vasos linfáticos, originadas de un secuestro del saco linfático y agrandados por un inadecuado drenaje a la falta de comunicación con los canales linfáticos centrales o a la secreción excesiva de células de revestimiento. La incidencia de estos tumores en el sistema linfático es baja con una frecuencia de 1,2 a 2,8/1.000 en niños, sin predilección por sexo. En el territorio maxilofacial se pueden distinguir tres tipos de linfangioma: linfangioma simple, linfangioma cavernoso e higroma quístico o linfangioma quístico. Clínicamente estas lesiones se presentan como masas de tejido blando indoloras y de crecimiento lento. Su aspecto clínico depende de la extensión de la lesión. Diversos métodos de tratamiento para el linfangioma han sido reportados en la literatura, siendo la escisión quirúrgica la indicada, principalmente cuando estructuras vitales no están involucradas en la lesión. En este artículo se presenta un caso de una paciente femenina de 13 años con un aumento de volumen en el bermellón del labio superior, con antecedente de síndrome Koolen De Vries, a la cual se le realizó la exéresis de la lesión.

Abstract Destruction of the harvest of cotton stalks should be done after it. However, destruction by ploughing prevents continuing with direct sowing, which makes chemical management an ally in soil conservation. The objective was to identify the most effective dose of 2,4-D, associated with different herbicides and the timing of administration for the control of transgenic cotton shoots for tolerance to glyphosate and glufosinate. The treatments consisted of the use of the herbicide 2,4-D, alone at doses of 670 and 1 340 g ha-1, and associated with the herbicides carfentrazone, flumiclorac, chlorimuron, flumioxazin and imazethapyr at three application times: 0 days after mechanical mowing (0 DAMM), 25 DAMM, and 0 DAMM + 25 DAMM. Regrowth evaluations were performed at 15, 30, and 45 days after the first and second applications, determining the dry biomass of the shoots. In terms of herbicide use time, the best results are obtained when they applied at 0 DAMM + 25 DAMM. Higher doses of 2,4-D (1 324 g ha-1) make it more efficient; in relation to herbicides, variations were perceived in their behavior depending on the time of evaluation, the application, and the dose of 2,4-D used. During the last measurement period, 45 days after application, 2,4-D+carfentrazone and 2,4-D+flumiclorac had the lowest dry shoot masses. The experiment was conducted in 2014. It was concluded that there is a lower rate of cotton regrowth when the application of the herbicides is repeated at 0 DAMM and 25 DAMM. The 1 324 g ha-1 dose of 2,4-D is more efficient. 2,4-D+carfentrazone and 2,4-D+flumiclorac promoted lower dry mass 45 days after administration of the treatments.

Resumen La destrucción de la cosecha de tallos de algodón debe realizarse después de esta. Sin embargo, la destrucción por arado impide continuar con la siembra directa, lo que hace que el manejo químico sea un aliado en la conservación del suelo. El objetivo fue identificar la dosis de 2,4-D, asociada a diferentes herbicidas y el momento de administración más eficazes para el control de retoños de algodón transgénico para tolerancia a glyphosate y glufosinate. Los tratamientos consistieron en el uso aislado del herbicida 2,4-D, a dosis de 670 y 1 340 g ha-1, y asociado a los herbicidas carfentrazone, flumiclorac, chlorimuron, flumioxazin y imazethapyr en tres tiempos de aplicación: 0 días después de la siega mecánica (0 DARM), 25 DARM, y 0 DARM + 25 DARM. Se evaluó el rebrote a los 15, 30 y 45 días después de la primera y segunda aplicación. Las evaluaciones de rebrote se realizaron a los 15, 30 y 45 días después de la primera y segunda aplicación, determinando la biomasa seca de los brotes. En cuanto al tiempo de uso de los herbicidas, los mejores resultados se obtienen cuando se suministró 0 DARM +25 DARM. Dosis más altas de 2,4-D (1 324 g ha-1) lo hacen más eficiente relaciona a los herbicidas se percibieron variaciones en su comportamiento según el tiempo de evaluación, la aplicación y la dosis de 2,4 D utilizada. Durante el último período de medición, 45 días después de la aplicación, 2,4-D+carfentrazone y 2,4-D+flumiclorac presentaron las masas secas de yema más bajas. El experimento se llevó a cabo en 2014. Se concluyó que existe una menor tasa de rebrote del algodón cuando se repite la aplicación de los herbicidas 0 DARM y 25 DARM. La dosis de 1 324 g ha-1 de 2,4-D es más eficiente. 2,4-D+carfentrazona y 2,4-D+flumiclorac promovieron una menor masa seca 45 días después de la administración de los tratamientos.

Resumen Este artículo problematiza las funciones de la Educación Física y del ocio en políticas implementadas en la ciudad de La Plata a partir de la transición a la democracia, en un proceso de apertura y de consolidación progresiva del espacio público urbano como nodo de la vida colectiva. Los usos políticos del deporte y de la recreación durante la celebración del centenario de La Plata (1982) intentaron sostener un orden dictatorial desestabilizado, apelando a las tradiciones fundacionales y al patrimonio cultural platense. La saga de intendentes radicales que gobernaron durante el resto de la década del 80 impulsó un perfil recreativo con anclaje en las periferias e incorporó al aerobismo como propuesta masiva. Sin embargo, durante los años 90 el justicialismo se focalizó en la deportivización y la internacionalización del casco urbano fundacional desde una perspectiva patrimonialista. Por último, en la primera década del siglo XXI comenzó la transición hacia un imaginario de ciudad saludable y sustentable, con énfasis en la actividad física y el ocio para el bienestar comunitario, incorporando prácticas alternativas y emergentes. Entre los hallazgos se destacan las intervenciones de estudiantes y profesoras/es en educación física en la coproducción de lo público y de lo urbano entre el Estado municipal y la sociedad platense, fundamentalmente, en coyunturas críticas.

Abstract This article problematizes the functions of Physical Education and leisure in policies implemented in the city of La Plata since the transition to democracy, in a process of opening and progressive consolidation of urban public spaces as a node of collective life. The political uses of sport and recreation during the celebration of La Plata’s centennial (1982) aimed to uphold a destabilized dictatorial order by appealing to the founding traditions and cultural heritage of La Plata. The mayors from the Radical party who governed during the rest of the 1980s promoted a recreational profile focused on the outskirts of the city and a proposal of aerobics for the masses. However, during the 1990s the Peronist administration prioritized promoting sports and internationalizing the foundational urban area from a cultural heritage perspective. Finally, in the 2000s, the transition towards an imaginary of a healthy and sustainable city began, with emphasis on physical activity and leisure for community wellbeing, incorporating new emerging and alternative practices. Among the findings, the contributions of physical education students and teachers to the co-production of the public and urban between the municipal government and the Platense community, mainly in critical situations, are highlighted.

Abstract Objective: To evaluate the usefulness of an Index of Suspicion Scale (ISS) based on the endoscopic and imaging correlation of the findings commonly observed in patients with conclusive histopathological confirmation of sinonasal papilloma (SPs). Study Design: Retrospective and correlational study. Material and Methods: A cohort of 103 consecutive patients with confirmed histopathological diagnosis of SPs were analyzed during the period 2000-2019, in which the endoscopic and radiological features were evaluated through a bimodal CT/MRM protocol, with whose uncovering a correlative scale of findings was developed that can allow to deduce its diagnosis. Results: All patients with SPs had endonasal polypoidal masses, of which only 91% of the cases showed opacified tomographic images coinciding with the endoscopic finding. Focal hyperostosis was observed in 79% patients. Sinonasal bony wall erosion was observed in 84%. Contoured cerebriform pattern images were identified in 86% of T1-weighted and T2-weighted MRI studies. Correlation of endoscopic and imaging findings, based on sensitivity measures and positive predictive values, showed results of diagnostic probability and reliability with an overall average global mean of 90%. The SPs assessment criteria in the proposed SIS considered all above-mentioned findings. Through this correlative scale, 19% of patients were detected with early SPs (low suspicion), 31% were found to have moderately growing SPs (moderate suspicion) and 50% were identified with SPs of greater size (high suspicion). Conclusion: The proposed ISS was able to allow a satisfactory clinical diagnosis of SPs. The correlation of the clinical criteria considered proved that it can be a useful guide in the timely clinical assessment of these neoplasms.

Abstract Objective: We aim to describe the clinical and pathological characteristics of patients with seminomatous germ cell tumour (SGCT) and residual masses following chemotherapy (CTX) with negative tumor markers taken to retroperitoneal lymph node dissection (RLND). Method: We included patients with SGCT and had a residual mass after CTX between 2007 and 2021 in our institution. Data was obtained in a retrospective fashion from our electronic database. Results: A total of 9 patients match the inclusion criteria. Above 66% of patients were Pt1, most of them were N2 (33.3%) and N3 (33.3%), 55.5% had a IIC clinical stage and all the patients had good risk following the International Germ Cell Cancer Collaborative Group (IGCCCG) classification. The majority of the patients were observed (55.5%), 33.3% were taken to RLND and one patient received CTX. Almost 66.6% of the patients taken to RLND had a complete resection of the mass and had viable tumor in 66.6% of the cases. Conclusions: In our retrospective study the RLND is a good option for these patients and allows a complete resection in most of the cases. When a complete resection is not possible is necessary to offer additional treatments.

Resumen Objetivo: Describir las características clínicas y patológicas de los pacientes con tumor germinal testicular tipo seminoma con masa residual posquimioterapia (post-QT) con marcadores tumorales negativos llevados a linfadenectomía retroperitoneal (LRP). Método: Se incluyeron pacientes con TGTS y masa residual post-QT entre el año 2007-2021 en nuestra institución. Los datos fueron obtenidos mediante la evaluación retrospectiva de nuestra base de datos electrónica. Resultados: Nueve pacientes cumplieron con los criterios de inclusión. Según la estadificación del TNM, seis pacientes eran pT1, mientras que tres (33,3%) eran N2 y N3. La mayoría de los pacientes, cinco en total, tenían un estadio clínico IIC y todos los pacientes se clasificaron como riesgo bueno según la clasificación del International Germ Cell Cancer Collaborative Group (IGCCCG). Se observaron cinco pacientes, tres fueron intervenidos con LRP y solo uno recibió QT. Solo en dos pacientes llevados a LRP se logró una resección completa de la masa y se encontró tumor viable en el 66,6% de los pacientes llevados a cirugía. Conclusión: En nuestra experiencia la LRP es viable en este tipo de pacientes, logrando la resección completa en la mayo ría de los casos. Cuando no se logra una resección completa es imprescindible ofrecer tratamientos adicionales.

ABSTRACT Introduction: renal masses are a biologically heterogeneous group of tumors that can be benign or malignant. Renal carcinomas represent 85% of solid tumors. Objective: to describe the anatomo-pathological results of renal masses in patients operated by laparoscopic surgery and identify the possible relation among the histological subtypes and other variables. Methods: an observational, analytic, cohort retrospective study that included 120 patients who underwent laparoscopic radical and partial nephrectomies, of those patients diagnosed with renal masses and treated from 2015-2020 was carried out. Descriptive statistics was utilized, and Student’s t-test and Ji-Square test (p>0,05) were used to correlate variables. Results: average age 58,2 years, males prevailed (65,8 %), incidental diagnosis (64,2 %), ASA II (45,8 %) and the R.E.N.A.L score was low/moderate. 85 % of the masses were malignant, in stage pT1a (53,9 %), significantly most were operated by radical nephrectomy (p=0,03). Cancer-specific survival was 98,8 % and mean follow-up time, 26,62 months (±1,97). The older age of the patients was associated to malignant tumors (p=0,0). Survival and tumor size were not related to histological subtypes (p>0,05, respectively). Conclusions: malignant renal masses prevailed and among them clear cell carcinoma, which was associated to older age. The malignant histological subtype and clear cell carcinoma were associated to the older age of the patients. Tumor size and survival were not associated to histological subtypes.

RESUMEN Introducción: las masas renales son un grupo biológicamente heterogéneo de tumores que pueden ser benignos o malignos. El carcinoma renal representa el 85 % de las masas sólidas. Objetivo: describir los resultados anatomopatológicos de las masas renales en pacientes operados mediante cirugía laparoscópica e identificar la posible relación entre los subtipos histológicos y otras variables. Métodos: estudio observacional, analítico, de cohorte, retrospectivo en una serie de 120 pacientes operados mediante nefrectomía radical y parcial laparoscópicas, del universo con masas renales, tratados entre 2015-2020. Se empleó estadística descriptiva y para correlacionar variables el t de Student y Ji cuadrado (p>0,05). Resultados: edad promedio 58,2 años. Predominó el sexo masculino (65,8 %), el diagnóstico incidental (64,2 %), los pacientes ASA II (45,8 %) y las masas de complejidad R.E.N.A.L baja/moderada. El 85 % de las masas fueron malignas, en estadio pT1a (53,9 %) y fue significativo que la mayoría fueran operadas por nefrectomía radical (p=0,03). La supervivencia cáncer-específica fue 98,8 % y el tiempo de seguimiento 26,6 meses (±1,97). La mayor edad de los pacientes se asoció a la malignidad de las masas (p=0,0). La supervivencia y el tamaño tumoral no se relacionaron con los subtipos histológicos (p>0,05, respectivamente) Conclusiones: predominaron las masas renales malignas, entre ellas el carcinoma células claras, lo que se asoció con el aumento de la edad. El tamaño tumoral y la supervivencia no se asociaron con los subtipos histológicos.
