Pharmacological induction of diabetes mellitus in pregnant female mice: a comparison of two doses and routes of administration.

OBJECTIVE: This study aimed to compare two routes of administration and different dosages of streptozotocin (STZ) for the pharmacological induction of gestational diabetes mellitus (GDM) in pregnant CD1 females. MATERIALS AND METHODS: 35 female CD1 mice were divided into 5 groups (n = 7). Diabetes mellitus (DM) was induced with STZ by two routes and two doses: 1) Control Group without administration of STZ (CL), 2) Intraperitoneal Group with 200 mg of STZ/Kg of weight (IP200), 3) Intraperitoneal Group with 230 mg of STZ/Kg of weight (IP230), 4) Subcutaneous Group with 200 mg of STZ/Kg of weight (SC200) and 5) Subcutaneous Group with 230 mg of STZ/Kg of weight (SC230). Body weight, food and water intake, glycemia, Homeostatic Model Assessment of Insulin Resistance Index (HOMA-IR), survival, and birth rate were identified. RESULTS: The SC230 group turned out to be the most effective dose and route for the induction of GDM in pregnant females. This scheme managed to reproduce sustained hyperglycemia with high HOMA-IR, the presence of polyphagia, polydipsia, and weight loss. In addition, the birth rate and survival were high compared to the other doses and routes of administration. CONCLUSIONS: The administration of a single dose of 230 mg/kg of weight by subcutaneous route supposes advantages compared to previously used models since it decreases the physiological stress due to manipulation and the costs since it does not require repeated doses or adjuvants such as high lipid diets to potentiate the diabetogenic effect of STZ.

Solitary fibrous tumor of the pleura with air cystic component.

We present an uncommon case of a solitary fibrous tumor of the pleura with the appearance of an air-containing cystic mass. We discuss the differential diagnosis through the imaging findings, the hypothetical origins of the air component, and the possible relationship between the air component and the aggressivity of the tumor.

[Translated article] A systematic review of the literature: The use of metaphyseal sleeves in revision total knee arthroplasty.

BACKGROUND AND OBJECTIVES: The purpose of this study is to analyse the indications, complications, survivorship and clinical/functional outcome of metaphyseal sleeves as a treatment option in revision total knee arthroplasty. MATERIAL AND METHOD: A systematic review was made following the PRISMA recommendations on the use of metaphyseal sleeves for revision total knee arthroplasty. We included prospective and retrospective studies published in the last 10 years looking at implant survivorship, clinical and functional outcome with a minimum follow-up of 2 years. RESULTS: The included studies showed good both functional and clinical outcomes. The overall reoperation rate was 16.2%, with an overall survival rate of 92.2% and aseptic survivorship of 98.2%. CONCLUSIONS: Metaphyseal sleeves are a good treatment option for this surgery, especially in AORI II or III type bone defects, achieving good intraoperative and primary stability of the implant, with good and rapid osseointegration.

Análisis radiográfico comparativo de tratamientos endodónticos: su posible aporte en la identificación forense / Comparative radiographic analysis of endodontic treatments: its possible contribution to forensic identification

Introducción: La identificación por cotejo de regis-tros odontológicos representa una metodología científicamente consolidada. La estrategia más co-mún reside en la comparación de odontogramas impresos o digitalizados, aunque se ha cuestionado cierta subjetividad al asentar dicha información. Los recursos imagenológicos constituyen una evidencia más confiable y objetiva, reduciendo el sesgo iden-tificatorio. La obtención de radiografías post mor-tem (PM) reproduciendo en lo posible las técnicas que han generado las imágenes ante mortem (AM) recuperadas, otorga una eficaz modalidad compa-rativa, aumentando su valor probatorio. Materiales y Métodos: Se efectuó la comparación entre radio-grafías panorámicas y periapicales tomadas a 10 pacientes atendidos en un consultorio particular de la ciudad de Quilmes, Provincia de Buenos Aires, don-de se visualizaban tratamientos de endodoncia. Los registros de ambas técnicas de imágenes se realiza-ron sobre los mismos sujetos entre los años 2010 y 2022. Se cotejaron 11 radiografías periapicales y 10 panorámicas, procediéndose a la digitalización de la totalidad de la muestra. Se clasificaron las imágenes de cada persona conforme a la fecha de obtención de las mismas. A las más antiguas se las catalogó con el color verde, representando el material AM, mien-tras que las más recientes se marcaron en color rojo, constituyendo la información PM. Resultados: Teniendo en cuenta los criterios estipulados por la Junta Americana de Odontología Forense (ABFO) se identificaron positivamente 7 casos estudiados, 2 fueron catalogados como identificación posible, en tanto que 1 se clasificó como insuficiente. No se re-gistraron exclusiones. Conclusión: Los tratamientos endodónticos podrían suministrar información pon-derable en procesos de identificación humana en virtud de la escasa probabilidad de sufrir alteracio-nes morfológicas y estructurales por su estratégica localización intradentaria, otorgando posibilidades concretas de establecer la identidad categórica de sujetos desconocidos (AU)

Introduction: Identification by comparison of dental records represents a scientifically consolidated methodology. The most common strategy lies in the comparison of printed or digitised odontograms, although certain subjectivity has been questioned when recording said information. Imaging resources constitute more reliable and objective evidence, reducing identification bias. Obtaining post-mortem (PM) radiographs reproducing the techniques that have generated the recovered ante-mortem (AM) images, provides an effective comparative modality, increasing its evidentiary value. Materials and Methods: A comparison was made between panoramic and periapical radiographs taken to 10 patients treated in a private office in the city of Quilmes, Province of Buenos Aires, where endodontic treatments were visualized. The records of both imaging techniques were carried out on the same subjects between 2010 and 2022. 11 periapical and 10 panoramic radiographs were collected, and the entire sample was digitized. The images of each person were classified according to the date they were obtained. The oldest ones were cataloged with the color green, representing the AM material, while the most recent ones were marked in red, constituting the PM information. Results: Taking into account the criteria stipulated by the American Board of Forensic Odontology (ABFO), 7 cases studied were positively identified, 2 were classified as possible identification, while 1 was classified as insufficient. No exclusions were recorded. Conclusion: Endodontic treatments could provide valuable information in human identification processes due to the low probability of suffering morphological and structural alterations due to their strategic intradental location, providing concrete possibilities of establishing the categorical identity of unknown subjects (AU)

Multicentre, prospective, randomized control non-inferiority trial of bladder catheter management in colon surgery.

AIM: Perioperative bladder catheterization is a controversial issue. Most current recommendations are based on data from open surgery extrapolated to enhanced recovery after surgery or fast-track programmes ranging between 24 and 48 h. The aim of this study is to provide a rationale for reducing catheterization time while at the same time avoiding acute urine retention (AUR), in patients undergoing scheduled laparoscopic colon surgery. METHOD: This is a multicentre, prospective, controlled, randomized non-inferiority study of bladder catheter management in patients undergoing scheduled laparoscopic colon surgery, randomized into two groups: experimental (with catheter removal immediately after surgery) and control (with catheter removal 24 h post-surgery). The main outcome will be the development of AUR, and secondary outcomes the development of urinary infection within the first 30 days and hospital stay. Demographic, surgical and pathological variables will also be evaluated, especially the development of adverse effects assessed according to the Clavien scale and the Comprehensive Complication Index. Following the literature, we assume an incidence of AUR of 11% and a margin of non-inferiority (delta) of 8% and estimate that a sample size of 208 patients per group will be required (with an estimated 10% of losses per group). CONCLUSIONS: In this study we try to demonstrate that the bladder catheter can be removed immediately after scheduled laparoscopic colon surgery, without increasing acute urine retention. This measure would offers the benefits of earlier mobilization and reduces catheter-related morbidity.

A systematic review of the literature: The use of metaphyseal sleeves in revision total knee arthroplasty. / Una revisión sistemática de la literatura: el uso de vainas metafisarias en cirugía de revisión de artroplastia de rodilla.

The carbon footprint of cataract surgery in Spain.

BACKGROUND AND PURPOSE: Climate change is one of the most important threats to human health nowadays. The healthcare industry produces a significant part of greenhouse gases (GHG) emissions. The aim of this study is to assess direct and indirect GHG emissions due to cataract surgery in Spain to identify opportunities for improving. METHODS: This observational case series study estimates and analyses the carbon footprint of a single cataract surgery using phacoemulsification in Ávila Hospital. ISO standard 14064 was applied. RESULTS: The carbon footprint of a single cataract surgery in Ávila Hospital was 86.62kg CO2eq. Medical and pharmaceutical equipment were responsible for 85% of GHG emissions. CONCLUSIONS: Collaboration between pharmaceuticals and ophthalmologists is important to improve the environmental impact of cataract surgery. Future research is needed to introduce changes that do not compromise patient and surgeon safety. Green surgery models could play an encouraging role in the new global health scene.

Oncological monitoring after transanal total mesorectal excision (TaTME) for rectal neoplasia.

BACKGROUND: The surgical treatment of choice for rectal neoplasia is total mesorectal excision (TME). The transanal approach enables a better approach in male and obese patients and/or those with a narrow pelvis and in patients with small tumors. Short-term results are comparable with those for laparoscopy or the open approach, but the medium- and long-term oncological data are sparse. The aim of the present study was to evaluate our early experience with transanal TME (TaTME). METHODS: This was a retrospective study conducted on patients who underwent TaTME at our center between August 2013 and April 2017 with a follow-up ≥ 3 years. Histopathology, complications, mortality, neoplastic recurrence and disease-free survival were analyzed. RESULTS: One hundred patients (68 men and 32 women,, median age 66.8 years [range 29.6-91.2 years]) were included. There were 67 T3 cases (67%) with 74 N0 cases (74%), the mesorectal quality was graded optimal for 87.6% and only 2 cases of radial margin involvement were detected (2%). The median follow-up period was 47.6 months (range 11.8-78.9 months). Eighteen cases of recurrence were diagnosed, of which 3 (3%) recurred locally with an average disease-free period of 43.1 months. Overall survival was 80% and mortality due to progression of disease was 13%. CONCLUSIONS: TaTME is a safe surgical procedure with surgical, anatomopathological and oncological results at 3 years (medium-term) comparable with those for the laparoscopic and open approaches. Better monitoring is required with studies of the long-term functional and quality of life outcomes, i.e., at 5 or 10 years.

COGNITION: a prospective precision oncology trial for patients with early breast cancer at high risk following neoadjuvant chemotherapy.

BACKGROUND: COGNITION (Comprehensive assessment of clinical features, genomics and further molecular markers to identify patients with early breast cancer for enrolment on marker driven trials) is a diagnostic registry trial that employs genomic and transcriptomic profiling to identify biomarkers in patients with early breast cancer with a high risk for relapse after standard neoadjuvant chemotherapy (NACT) to guide genomics-driven targeted post-neoadjuvant therapy. PATIENTS AND METHODS: At National Center for Tumor Diseases Heidelberg patients were biopsied before starting NACT, and for patients with residual tumors after NACT additional biopsy material was collected. Whole-genome/exome and transcriptome sequencing were applied on tumor and corresponding blood samples. RESULTS: In the pilot phase 255 patients were enrolled, among which 213 were assessable: thereof 48.8% were identified to be at a high risk for relapse following NACT; 86.4% of 81 patients discussed in the molecular tumor board were eligible for a targeted therapy within the interventional multiarm phase II trial COGNITION-GUIDE (Genomics-guided targeted post neoadjuvant therapy in patients with early breast cancer) starting enrolment in Q4/2022. An in-depth longitudinal analysis at baseline and in residual tumor tissue of 16 patients revealed some cases with clonal evolution but largely stable genetic alterations, suggesting restricted selective pressure of broad-acting cytotoxic neoadjuvant chemotherapies. CONCLUSIONS: While most precision oncology initiatives focus on metastatic disease, the presented concept offers the opportunity to empower novel therapy options for patients with high-risk early breast cancer in the post-neoadjuvant setting within a biomarker-driven trial and provides the basis to test the value of precision oncology in a curative setting with the overarching goal to increase cure rates.

EXPRESSION OF CHEMOKINE (C-C MOTIF) RECEPTOR 7 IN PROSTATE CANCER TISSUE OF YOUNG PATIENTS AND IN METASTATIC CANCER CELLS.

BACKGROUND: Chemokine (C-C motif) receptor 7 (CCR7) is a chemokine receptor involved in the carcinogenesis of several types of tumors due to its promoting action in epithelial-mesenchymal transition events, invasion, angiogenesis and metastasis. However, its role in prostate cancer (PCa) remains unclear. AIM: To evaluate CCR7 expression by immunohistochemistry in prostate tumors from young patients and to determine the possible relationship with the clinicopathological characteristics. MATERIALS AND METHODS: We analyzed retrospectively paraffin-embedded tissue sections from 23 young PCa (≤ 55 years old) patients and evaluated the transcriptomic expression in the TCGA database. RESULTS: Expression of CCR7 was observed in 15 cases (65%). The tissue samples from younger patients (≤ 50 years) were mostly positive in 72.7% (8/11) of cases. High grade GS (≥ 3) tumors were CCR7-positive in 71% cases. The malignant cells present in lymph nodes were CCR7 positive in 100% cases. The bioinformatic analysis showed a high CCR7 expression associated with the presence of metastasis (FC = 2.6, p = 0.03) in the Cancer Genome Atlas (TCGA) PCa cohort (PRAD). CONCLUSION: We showed that CCR7 expression in tumors from young patients is associated with the early onset of the disease and could also be related to lymph node metastasis.

Dosimetric analysis of graphitic carbon nitride quantum dots exposed to a gamma radiation for a low-dose applications.

In this study, graphitic carbon nitride quantum dots (g-C3N4QDs) were synthesized using different solvents, characterized, and then exposed to a gamma-ray source (137Cs) at irradiation doses of 0.1, 1.48, 2.05 and 3.25 Gy. The intensities of the emission bands progressively were attenuated as the received dose of gamma radiation increased. The changes were quantified with the help of a non-linear fit model. The material showed promising use as a dosimeter for low-dose radiation applications.

Tranexamic acid in cardiac surgery: Are low doses enough?

OBJECTIVES: Tranexamic acid is used to prevent hyperfibrinolysis and reduce postoperative bleeding and blood transfusions in on-pump cardiac surgery. We evaluate the efficacy of low or high dose tranexamic acid in a prospective cohort study conducted in Valencia. MATERIALS AND METHODS: A total of 427 patients were recruited between January 2019 and January 2020, 207 in the Hospital General Universitario (low dose [LD]) and 220 in the Hospital Universitario y Politécnico La Fe (high dose [HD] and intermediate dose [ID]). We recorded the presence of hyperfibrinolysis on rotational thromboelastometry, intra- and postoperative administration of blood products, chest tube output within the first 12 h, and incidence of convulsions. Univariate and multivariate comparisons were performed. Univariate analysis of all categories was performed after propensity score matching between LD and HD and between LD and ID. RESULTS: There were no statistically significant differences in: appearance of hyperfibrinolysis, administration of blood products, postoperative chest tube output within the first 12 h, or occurrence of convulsions. Group LD received less fibrinogen than group HD (P = .014) and ID (P = .040) but more fresh frozen plasma than group ID (P = .0002). CONCLUSIONS: Administration of low-dose tranexamic acid is as effective as higher doses in hyperfibrinolysis prophylaxis and the prevention of postoperative bleeding in cardiac surgery.

Correlaciones entre el test de velocidad en 4 metros y el test de caminata en 6 min en enfermos respiratorios crónicos / Correlations between the 4 meter speed test and the 6-minute walking test in chronic respiratory patients

Resumen La prueba de velocidad de marcha en 4 metros (T4M) es considerada sustituto de la caminata en 6 min (TC6M) en EPOC. Sin embargo, no ha sido bien investigada en otras enfermedades respiratorias. Durante un año estudiamos pacientes que concurrieron a nuestra Unidad para realizar el TC6M midiendo la velocidad alcanzada en 4 metros, 2 h previo a realizar el TC6M. De 162 pacientes 99 eran mujeres. La edad media fue de 65 años, peso de 73 kg, talla de 158 cm, IMC 29,4 kg/m2. 36% tenían fibrosis pulmonar idiopática, 17% EPOC, GOLD IV,11% EPOC, GOLD III, 12% apnea de sueño y 12% otras enfermedades. No hubo diferencia para los distintos diagnósticos en ambos tests. La distancia media en TC6Mfue 368,5 m la velocidad: 1,01 m/s en T4M.Hubo una correlación positiva significativa entre ambos test: alto rendimiento en T4M es equivalente a un alto rendimiento en el TC6M. Hubo correlación negativa con la edad y positiva con la estatura. Al año de seguimiento 16 pacientes habían fallecido, siendo estos los que habían obtenido los más bajos rendimientos en ambos tests (T4M: 0,69 m/s y 248,1 m en TC6M) La posibilidad de sobrevida cayó a 20% en aquellos individuos que alcanzaron una velocidad inferior a 0,69 m/s. Es posible sustituir el TC6M por el T4M en pacientes con diferentes patologías respiratoria, podemos predecir la muerte por cualquier causa si un sujeto camina a una velocidad ≤ 0,69 m/s, T4M es barato y fácil de realizar en atención primaria, sirviendo como evaluación de riesgo para referir a un centro más complejo.

4-Meter Gait Speed Test (4MGST) a frailty test, is considered a surrogate for the 6-Minute Walk Test (6MWT) in COPD. However, it has not been investigated in other respiratory conditions. Over a year, we studied patients attending our Unit for evaluation with 6MWT, measuring the speed they achieved walking 4 m, 2 h before performing 6MWT. 162 patients (99 women) were studied; series' mean values were: age 65 years-old; body weight, 73 kg; height, 158 cm and BMI, 29.4 kg/m2. 36% of them had idiopathic pulmonary fibrosis, 17% GOLD IV COPD, 11% GOLD III COPD, 12% pulmonary arterial hypertension, 12% obstructive apnea-hypopnea syndrome, and 12% other conditions. ANOVA showed no difference between diagnostic categories for both test. Average score in 6MWT was 368.5 m and 1.01 m/s in 4MGST. Pearson correlation coefficient revealed significant positive correlation between results of both tests: high score in 4MGST is equivalent to high score in 6MWT. There was negative correlation with age and positive correlation with height. At one year follow-up, 16 patients had died. They obtained significantly lower scores in both tests (4MGST: 0.69 m/s and 6MWT: 248.1 m) Survival chance fell to 20% for patients walking slower than 0.69 m/s. It is possible to replace TC6M with T4M in patients with different respiratory pathologies, we can predict death for any cause if a subject walked at ≤ speed at 0.69 m/s. T4M is cheap and easy to perform in primary care, serving as a risk assessment to refer to a more complex center.

Chronic obstructive pulmonary disease in severe mental illness: A timely diagnosis to advance the process of quitting smoking.

BACKGROUND: This study has two main objectives: to describe the prevalence of undetected chronic obstructive pulmonary disease (COPD) in a clinical sample of smokers with severe mental illness (SMI), and to assess the value of the Tobacco Intensive Motivational Estimated Risk tool, which informs smokers of their respiratory risk and uses brief text messages to reinforce intervention. METHOD: A multicenter, randomized, open-label, and active-controlled clinical trial, with a 12-month follow-up. Outpatients with schizophrenia (SZ) and bipolar disorder were randomized either to the experimental group-studied by spirometry and informed of their calculated lung age and degree of obstruction (if any)-or to the active control group, who followed the 5 A's intervention. RESULTS: The study sample consisted of 160 patients (71.9% SZ), 78.1% of whom completed the 12-month follow-up. Of the patients who completed the spirometry test, 23.9% showed evidence of COPD (77.8% in moderate or severe stages). TIMER was associated with a significant reduction in tobacco use at week 12 and in the long term, 21.9% of patients reduced consumption and 14.6% at least halved it. At week 48, six patients (7.3%) allocated to the experimental group achieved the seven-day smoking abstinence confirmed by CO (primary outcome in terms of efficacy), compared to three (3.8%) in the control group. CONCLUSION: In this clinical pilot trial, one in four outpatients with an SMI who smoked had undiagnosed COPD. An intensive intervention tool favors the early detection of COPD and maintains its efficacy to quit smoking, compared with the standard 5 A's intervention.

Estimación de costos unitarios directos de atención curativa de dengue en Ecuador 2020 / Estimate of direct unit costs of curative Dengue care in Ecuador 2020

El dengue es una enfermedad viral aguda transmitida a través de la picadura del mosquito (artrópodo) Aedes aegypti infectado con cualquiera de los serotipos de virus dengue. Son virus envueltos, de 40 a 50 nm de diámetro, con cápside icosaédrica y genoma de ácido ribonucleico (ARN) monocatenario, no segmentado, de polaridad positiva perteneciente al género flavivirus de la familia Flaviviridae. El análisis filogenético de las distintas cepas del virus dengue indica que la diseminación global ha dado lugar a distintos genotipos dentro de cada serotipo. En el quinquenio 2015-2020, en Ecuador, se notificaron en toda la región 76.085 casos de dengue. La atención unitaria hospitalaria para el tratamiento del dengue de las unidades de atención sanitaria hospitalarias (A, B, C), generaron un costo total promedio de 498,04 $ con una desviación estándar de ± 40,36, en el Ecuador para el año 2020. Cabe considerar, por otra parte, que el costo unitario directo promedio en ($) de la atención sanitaria en las entidades hospitalarias estudiadas en la presente investigación, generanron un gasto total para el tratamiento hospitalario de 9.585.114,02. Al mismo tiempo en los 2.135 pacientes diagnosticados con dengue que presentaron signos de alarma y requirieron cuatro días de hospitalización, señalando un gasto total para el tratamiento de 1.471.385,06. Por su parte los 51 pacientes que fueron diagnosticados con dengue grave, generaron un costo unitario total en las unidades hospitalarias de 134.152,54. Los resultados son conservadores, porque algunos componentes importantes no se incluyeron en los costos relacionados con el dengue.En ausencia de vacunación, y siendo los programas de control del vector la estrategia básica para mitigar la propagación del dengue, esta enfermedad seguirá produciendo una carga económica y social considerable en el Ecuador, lo que se refleja en el costo total de la enfermedad(AU)

Dengue is an acute viral disease transmitted through the bite of the mosquito (arthropod) Aedes aegypti infected with any of the dengue virus serotypes. They are enveloped viruses, 40 to 50 nm in diameter, with an icosahedral capsid and a single-stranded, non-segmented ribonucleic acid (RNA) genome of positive polarity belonging to the genus Flavivirus of the Flaviviridae family. Phylogenetic analysis of the different dengue virus strains indicates that global spread has given rise to different genotypes within each serotype. In the five-year period 2015-2020, in Ecuador, 76,085 cases of dengue were reported throughout the region. The hospital unit care for the treatment of dengue in the hospital health care units (A, B, C), generated an average total cost of $ 498.04 with a standard deviation of ± 40.36, in Ecuador for the year 2020. It should be considered, on the other hand, that the average direct unit cost in ($) of health care in the hospital entities studied in the present investigation, generated a total cost for hospital treatment of 9,585,114.02. At the same time, in the 2,135 patients diagnosed with dengue who presented alarm signs and required four days of hospitalization, indicating a total cost for treatment of 1,471,385.06. On the other hand, the 51 patients who were diagnosed with severe dengue, generated a total unit cost in the hospital units of 134,152.54. The results are conservative, because some important components were not included in the costs related to dengue. In the absence of vaccination, and with vector control programs the basic strategy to mitigate the spread of dengue, this disease will continue to produce an economic burden and considerable social in Ecuador, which is reflected in the total cost of the disease(AU)

The French national network dedicated to rare gynecological cancers diagnosis and management could improve the quality of surgery in daily practice of granulosa cell tumors. A TMRG and GINECO group Study.

OBJECTIVE: The French national rare gynecological tumor network has been established to improve the quality of care through offering expertise in double reading histological diagnosis, reviewing cases and guiding management of these tumors through specialized multidisciplinary tumor boards and online clinical guidelines (www.ovaire-rare.com). The aim of this study is to evaluate the impact of the development and implementation of this network by assessing the conformity of medical practice with the guidelines concerning the granulosa cell tumors (GCTs). METHODS: This is a French nationwide study, including 463 patients (out of the 639 identified patients) with a definitive diagnosis of GCT between 2011 and 2016. Surgical practices were analyzed for conformity with the current guidelines (www.ovaire-rare.org). Medical records, surgical and pathological reports were systematically analyzed. Total conformity was defined by a conservative (unilateral salpingo-oophorectomy) or radical surgery (hysterectomy and bilateral salpingo-oophorectomy) including surgical staging (omentectomy, peritoneal biopsies and peritoneal cytology) according to the FIGO stage. Partial conformity referred to a conservative or radical surgery without surgical staging and non-conformity was defined as a non-optimal surgery as recommended by the guidelines. RESULTS: Median age at diagnosis was 49 years old (range 10-89). The median size of tumor was 94 mm (range 5-400). Radical surgery was performed in 240 patients (52%); while a fertility-sparing surgery was performed in 98 cases (21%). A surgical staging was performed in 76 cases (16%) and an evaluation of the endometrium in 289 cases (62%). Surgery was fully compliant with the guidelines in 65 patients (14%), partially compliant in 213 patients (46%), non-compliant in 137 patients (30%) and not assessable in 48 cases (10%). A statistically significant difference for compliance was observed in restaging surgery (p < 0,001), radical surgery (p = 0,017) and the period (before or after) of the implementation of the network (p < 0,001). Survival analyses did not allow us to demonstrate a significant difference in overall survival nor in PFS although there was a trend in favor of optimal surgery compared to incomplete/non optimal surgery. CONCLUSION: Surgical management's conformity to the guidelines increases over time from 2011 to 2016. According to this study, the implementation of a national network dedicated to rare gynecologic tumors seems to significantly improve the surgical management of the patients with ovarian granulosa cell tumors.
