ABSTRACT

Objetivo: Validar la técnica de ganglio centinela utilizando verde de indocianina en la estadificación del cáncer de endometrio. Método: Realizamos un estudio prospectivo entre enero y diciembre de 2021. Se incluyeron todas las pacientes portadoras de cáncer de endometrio clínicamente en etapa 1, de todos los grados de diferenciación e histologías. Todas las pacientes fueron sometidas a una estadificación laparoscópica. Se inició el procedimiento con identificación de ganglio centinela utilizando verde de indocianina. Posteriormente, se completó la cirugía de estadiaje estándar en todas las pacientes. Los ganglios centinelas fueron procesados con técnica de ultraestadiaje. Resultados: Se incluyeron 33 pacientes. El 81% presentaron histología endometrioide. El 100% fueron sometida además a una linfadenectomía pelviana estándar y el 20% a una linfadenectomía paraaórtica simultáneamente. Se detectó al menos un ganglio centinela en el 100% de los casos. La detección bilateral ocurrió en el 90,9%. La localización más frecuente fue la fosa obturatriz y la arteria hipogástrica. Obtuvimos una sensibilidad del 90% para detectar enfermedad ganglionar y un valor predictivo negativo del 95,8%. Conclusiones: La técnica de ganglio centinela utilizando verde de indocianina es replicable. Los resultados de nuestra serie nos permiten realizar procedimientos menos agresivos al estadificar el cáncer de endometrio.


Objective: To validate sentinel node mapping using indocyanine green in endometrial cancer staging. Method: A prospective study was conducted between January and December 2021. All patients with clinically stage 1 endometrial cancer, of all grades and histologies were included. All patients underwent laparoscopic staging. The procedure began with identification of the sentinel node using indocyanine green. Subsequently, standard staging surgery was completed in all patients. Sentinel nodes were processed using ultrastaging technique. Results: Thirty-three patients were enrolled. 81% of cases had endometrioid histology. All patients also underwent a standard pelvic lymphadenectomy and in 20% of cases a para-aortic lymphadenectomy. At least one sentinel node was detected in 100% of the cases. Bilateral detection occurred in 90.9%. The most frequent location was obturator fossa and hypogastric artery. Sensitivity to detect lymph node disease was 90% and negative predictive value 95.8%. Conclusions: Sentinel lymph node mapping using indocyanine green is a replicable technique. Our results allows us to perform less aggressive procedures in endometrial cancer staging.

ABSTRACT

Abstract Objective To evaluate the presence of residual disease in the uterine specimen after hysteroscopic polypectomy or polyp biopsy in patients with endometrioid endometrial cancer (EC). Methods We analyzed a series of 104 patients (92 cases from the Hospital AC Camargo and 12 from the Hospital do Servidor Público Estadual de São Paulo) with polyps that were diagnosed by hysteroscopy, showing endometrioid EC associated with the polyp or in the final pathological specimen. Patients underwent a surgical approach for endometrial cancer from January 2002 to January 2017. Their clinical and pathological data were retrospectively retrieved from the medical records. Results In78cases (75%), thepolyphad EC, and in 40(38.5%), itwas restricted tothe polyp, without endometrial involvement. The pathologic stage was IA in 96 cases (92.3%) and 90 (86.5%) had histologic grade 1 or 2. In 18 cases (17.3%), there was no residual disease in the final uterine specimen, but only in 9 of them the hysteroscopy suggested that the tumor was restricted to the polyp. In 5 cases (4.8%) from the group without outside of the polyp during hysteroscopy, myometrial invasion was noted in the final uterine specimen. This finding suggests the possibility of disease extrapolation through the base of the polyp. Conclusion Patients with endometrioid EC associated with polyps may have the tumor completely removed during hysteroscopy, but the variables shown in the present study could not safely predict which patient would have no residual disease.


Resumo Objetivo Avaliar a presença de doença residual no exame anatomopatológico definitivo de pacientes com câncer de endométrio endometrioide após polipectomia ou biópsia de pólipo histeroscópica. Métodos Analisamos 104 pacientes (92 casos do Hospital AC Camargo e 12 casos do Hospital do Servidor Público Estadual de São Paulo) com pólipos diagnosticados durante histeroscopia e cuja biópsia histeroscópica ou exame patológico final do útero acusaram câncer de endométrio endometrioide. As pacientes foram submetidas a cirurgia para câncer de endométrio de janeiro de 2002 a janeiro de 2017. Os dados clínicos e anatomopatológicos de cada paciente foram retirados dos prontuários médicos Resultados Em 78 casos (75%), o pólipo continha a neoplasia, e em 40 (38.5%), ela estava restrita ao tecido do pólipo, sem envolvimento endometrial adjacente. O estadio final foi IA em 96 casos (92.3%) e em 90 (86.5%) tratava-se de grau 1 ou 2. Em 18 casos (17.3%), não havia doença residual no espécime uterino, mas emapenas 9 deles a histeroscopia sugeriu doença restrita ao pólipo. Em 5 casos (4.8%), não havia doença aparente extrapólipo na histeroscopia, mas havia invasão miometrial, sugerindo extravasamento do tumor pela base do pólipo. Conclusão Pacientes com câncer de endométrio associado a pólipos podem ter o tumor completamente removido durante a histeroscopia, mas, com as variáveis avaliadas, é difícil predizer com segurança qual paciente ficará sem tumor residual.

ABSTRACT

Radiation therapy plays an important role in the adjuvant treatment of patients with early endometrial carcinoma. Vaginal stump is a common site of disease failure for early endometrial carcinoma patients with intermediate-high risk factors for recurrence. Compared with external beam radiotherapy, vaginal brachytherapy (VBT) can achieve comparable local control rate with fewer toxicities. In this article, research progresses upon the application of VBT in patients with early endometrial carcinoma after hysterectomy were investigated from multiple perspectives of the selection of patients, the selection of vaginal applicator, factors influencing dose distribution, image-guided adaptive brachytherapy, the design and implementation of radiotherapy regime. In addition, the application of intensity-modulated VBT and the usage of novel quality assurance equipment were also discussed.

ABSTRACT

Abstract Objective: To determine whether there are substantive differences between the initial interpretations of magnetic resonance imaging (MRI) scans acquired at outside facilities and the second-opinion interpretations of radiologists specializing in gynecologic oncology at a tertiary cancer center, among patients referred for endometrial cancer staging. Materials and Methods: This was a retrospective, comparative analysis of 153 initial and second-opinion MRI reports for endometrial cancer staging officially submitted for review by radiologists specializing in gynecologic oncology. For each case, the relationship between the initial and second-opinion reports, regarding the suggested diagnosis and the clinically relevant MRI findings reported, was categorized as "agreement" or "disagreement". Histopathology was used in order to establish the definitive diagnosis. Results: Disagreement was found in 58 (37.9%) of the 153 cases. Second-opinion interpretations reported findings that affected the preoperative cancer staging and could have led to a change in treatment in 38 cases (24.8%); that did not affect the preoperative staging but provided information that was more accurate in 8 (5.2%); and that suggested a new cancer diagnosis in 12 (7.8%). In 37 cases (24.2%), there was a potential for changes in patient care. Among the 58 cases of disagreement, a definitive (histopathological) diagnosis was made in 41 (70.7%). In 31 (75.6%) of those 41 cases, the second-opinion report was more accurate than was the initial report. Conclusion: Discordant interpretations of MRI examinations, which can have a substantial effect on the clinical management of patients, appear to be common.


Resumo Objetivo: Determinar se existe diferença substancial entre os relatórios de estudos de ressonância magnética realizados no exterior, comparativamente com os relatórios de segunda opinião elaborados por radiologistas subespecializados em oncologia ginecológica, em pacientes encaminhados a centro de referência terciária para estadiamento do câncer do endométrio. Materiais e Métodos: Foi efetuado estudo retrospectivo com comparação e análise dos respectivos relatórios, de 153 estudos de ressonância magnética submetidos para uma segunda interpretação num centro oncológico. Cada conjunto de relatórios foi categorizado como "concordante" ou "discordante", relativamente aos achados radiológicos referidos e ao diagnóstico final sugerido. A análise anatomopatológica foi utilizada para determinar o diagnóstico definitivo. Resultados: Foram identificadas discordâncias em 58/153 (37,9%) relatórios. As segundas interpretações: alteraram o estádio pré-operatório e motivaram uma potencial alteração da abordagem terapêutica em 38/153 (24,8%), forneceram informação diagnóstica mais precisa sem alterar o estádio pré-operatório em 8/153 (5,2%) e sugeriram diagnóstico de um câncer novo em 12/153 (7,8%). Quando foi possível obter um diagnóstico definitivo, encontrado em 41/58 casos (70,7%), o relatório de segunda opinião mostrou ser mais correto em 31 desses 41 estudos (75,6%). Conclusão: As discrepâncias entre relatórios realizados no exterior e reavaliados por radiologistas subespecializados são frequentes, motivando uma potencial alteração da abordagem terapêutica num número relevante de casos.

ABSTRACT

Objective@#To evaluate Magnetic Resonance Imaging (MRI) at 3.0T in differential diagnosis of the origin of adenocarcinoma at the junction of the lower uterine segment and endocervix.@*Methods@#71 patients with adenocarcinoma at the junction of the lower uterine segment and endocervix were retrospectively collected. Pelvic MR examinations, including diffusion-weighted imaging (DWI) and dynamic contrast-enhanced (DCE) sequences, were performed within 2 weeks before surgery. MR images were analyzed and measured by two radiologists, including the location of the tumor center, the enhancement pattern, the anterior and posterior diameters, the left and right diameters, the upper and lower diameters, and the apparent diffusion coefficient (ADC) of the tumor. Immunohistochemical method was used as gold standard in distinguishing cervical adenocarcinoma and uterine adenocarcinoma.@*Results@#The upper and lower diameters of uterine adenocarcinoma were [(5.80±2.31) cm], significantly larger than those of cervical adenocarcinoma [(4.16±2.17) cm, P=0.009]. Using 4.5cm as the best cutoff point value, the sensitivity and specificity in distinguishing uterine adenocarcinoma and cervical adenocarcinoma were 68.4% and 65.4%, respectively. According to the location of tumor center, the sensitivity and specificity were 84.2% and 73.1%, respectively. Using tumor enhancement pattern as the criterion, the sensitivity and specificity of diagnosing uterine adenocarcinoma and cervical adenocarcinoma were 68.4% and 80.8% respectively.@*Conclusions@#MRI has certain clinical value in evaluating the origin of adenocarcinoma at the junction of the lower uterine segment and endocervix. The lesions can be diagnosed according to the main location, the characteristics of dynamic enhancement and the growth pattern of the tumor.

ABSTRACT

Neste estudo, descreve-se o perfil clínico das pacientes e as características histopatológicas dos carcinomas de endométrio tratados no setor de Oncologia Genital do Hospital de Clínicas de Porto Alegre (HCPA), assim como as formas de tratamento, fatores prognósticos e sobrevida. Métodos: Estudo de coorte histórica incluindo todas as pacientes submetidas a tratamento cirúrgico primário entre 1996 e 2012. Após revisão de prontuários médicos, foram analisadas as variáveis idade, status hormonal, tipo histológico e grau tumoral, invasão miometrial, estadiamento cirúrgico, cirurgia realizada, tratamento complementar e sobrevida. Resultados: Cento e sessenta e quatro pacientes foram incluídas no estudo, com idade média de 64,2 anos (31-95 anos), sendo quase 90% delas pós-menopáusicas. O tempo de seguimento variou de 4 dias a 14,6 anos. O tipo histológico endometrioide foi o mais encontrado (78% dos casos). A histerectomia com salpingo-ooforectomia bilateral com linfadenectomia pélvica foi a cirurgia mais realizada (77,5%). Tratamento complementar foi realizado em 57,9% das pacientes, sendo a radioterapia o tratamento de escolha em 87,4% deles. Ocorreram 36 óbitos (22%) durante o seguimento, com uma sobrevida média global de 125 meses. Em análise bivariada, idade ≥ 65 anos, tipo histológico não endometrioide, tumores pouco diferenciados (G3), invasão miometrial ≥ 50% e metástase linfonodal relacionaram-se significativamente a um menor tempo de sobrevida. Em análise multivariada, a histologia não endometrioide, estádio III, estádio IV e a presença de comprometimento linfonodal foram significativamente associados ao óbito. Conclusão: Os resultados encontrados são compatíveis com a literatura existente e vêm em acréscimo à escassa estatística nacional...


This study describes the clinical profile and the hystopathologic characteristics of endometrial carcinomas from patients treated at the Gynecologic Oncology department of Hospital de Clínicas de Porto Alegre (HCPA), as well as the forms of treatment, prognostic factors, and survival. Methods: Historic cohort study including all patients subjected to primary surgical treatment between 1996 and 2012. After review of the medical records, the variablesage, hormonal status, tumor histologic type and grade, myometrial invasion, surgical staging, performed surgery, complementary treatment, and survival were analyzed. Results: One hundred sixty four patients were included, with a mean age of 64.2 years (31-95 years), of which almost 90% were postmenopausal women. Follow-up time ranged from 4 days to 14.6 years. Endometrioid adenocarcinoma was the most frequently histological type (78% of cases). Hysterectomy with bilateral salpingooophorectomy plus pelvic linfadenectomy was the most frequently performed surgery (77.5%). Adjuvant treatment was held in 57.9% of the patients, with radiotherapy being the treatment of choice in 87.4%. Thirty-six deaths (22%) occurred during followup, with a mean overall survival of 125 months. In the bivariate analysis, age ≥ 65 years, non-endometrioid histology, poorly differentiated tumors (G3), myometrial invasion ≥ 50%, and lymph node metastasis were correlated to lower survival. In the multivariate analysis, non-endometrioid histology, stage III, stage IV and lymph node metastasis were significantly associated with death. Conclusion: The results found are compatible with the existing literature and contribute to the scarce existing national statistics...

ABSTRACT

Objective Controversies exist as to the influences of the characteristics of lymph node metastasis ( LNM) on the prognosis of low-grade endometrial carcinoma ( LGEC) .The aim of this study was to investigate the risk factors of LNM and their im-pact on the prognosis of LGEC. Methods This study included 218 LGEC patients treated by retroperitoneal lymph node dissection. We analyzed the pathologic characteristics of LNM and its relationship with the survival rate of the patients. Results LNM was ob-served in 37 of the 218 patients (16.97%), including 20 cases of pelvic (54.05%), 6 cases of para-aortic (16.22%), and 11 ca-ses of both pelvic and para-aortic ( 29.73%) LNM.Independent risk factors of LNM included deep myometrial infiltration ( OR:5.21, 95%CI:2.77-9.81), cervical stromal involvement (OR:3.15, 95% CI:1.12-8.35), lymphovascular invasion (OR:1.15, 95%CI:1.02-1.30), and abnormally high serum CA125 (OR:3.46, 95%CI:1.56-7.67) (P<0.05).There were sig-nificant differences in the 3-year survival rate between the patients with LNM and those without LNM (83.8%vs 95.0%, P<0.05) as well as in the 3-year tumor-free survival rate (73.0% vs 90.1%, P<0.05). Conclusion Deep myometrial infiltration, cervical stromal involvement, lymphovascular invasion, and abnormally high serum CA125 are the risk factors of LNM in LGEC patients, and LNM affects the prognosis of the LGEC patients.

ABSTRACT

A 54-year-old woman presenting with dizziness was diagnosed with a metastatic brain tumor. Imaging studies to identify the primary cancer revealed endometrial thickening with a left adnexal mass, enlarged bilateral external iliac lymph nodes, and multiple attenuated nodules in both lobes of the thyroid gland with enlarged central neck nodes. After curettage of the uterine endometrium and ultrasonography-guided gun biopsy of the thyroid gland to confirm uterine and thyroid cancers, respectively, total abdominal hysterectomy with bilateral salpingo-oophorectomy and total thyroidectomy with bilateral central neck dissection were performed. Histopathologic examination of the removed tissues demonstrated both endometrial carcinoma metastasis to the thyroid gland and primary thyroid cancer with synchronous central neck node metastasis originating in the endometrium and thyroid. Three of the four right central lymph nodes were positive for metastatic papillary carcinoma; on the other hand, the remaining right central lymph node and one of the two left central lymph nodes were confirmed to be positive for metastatic endometrial carcinoma.

ABSTRACT

Objective:To investigate the expressions of peroxisome proliferator-activated receptor gamma (PPARγ), estrogen re-ceptor alpha (ERα), and estrogen receptor beta (ERβ) in endometrial carcinoma and to analyze their correlations and clinical signifi-cance. Methods:Immunohistochemical assay and Western blot were used to detect the expressions of PPARγ, ERα, and ERβin normal endometrial tissues and well-differentiated, moderately differentiated, and poorly differentiated endometrial carcinomas. Results:PPARγexpression was significantly lower in endometrial carcinoma than in the normal endometrium and was intimately associated with cli-ni-copathologic variables. ERαexpression gradually decreased in moderately and poorly differenti-ated endometrial carcinomas. How-ever, no significant differences were found between the normal endometrium and well-differentiated endometrial carcinoma. ERβex-pression only decreased in the poorly differentiated endometrial carcinoma. No significant association was observed between ERβand clinicopathologic variables. Pearson correlation analysis showed a significant positive cor-relation between the expressions of PPARγand ERα. No correlations were observed between the expressions of ERαand ERβand between that of ERβand PPARγ. Conclusion:The expression lev-els of PPARγand ERαwere significantly associated with the clinicopathologic stage of endometrial carcinoma, and have essential functions in endometrial tumorigenesis and tumor progression.

ABSTRACT

OBJECTIVES: The objective of this study is to evaluate the prevalence of endometrial premalignant and malignant polyps in women who underwent hysteroscopic polypectomies, and to investigate whether clinical parameters predict histopathologic outcomes. METHODS: A review was carried out on the medical records of patients who had undergone hysteroscopic endometrial polypectomy from January 2010 to December 2011. One thousand one hundred ninety-six women who ranged in age from 16 to 81 years were included in the study. Polyps were classified as benign (endometrial polyps and polyps with non-atypical simple hyperplasia and non-atypical complex hyperplasia), premalignant (polyps with atypical simple hyperplasia or atypical complex hyperplasia), or malignant. A statistical analysis was then performed. RESULTS: Histopathologically, 96.7% benign, 1.1% premalignant, and 2.2% malignant lesions were detected. Abnormal uterine bleeding and postmenopause were the only factors which were determined to be associated with a higher risk of malignancy, with an odds ratios of 5.07 (95% CI, 2.25-11.41) and 3.41 (95% CI, 1.14-10.24), respectively. CONCLUSION: The risk factors associated with premalignant and malignant endometrial polyps include abnormal uterine bleeding and menopause.

ABSTRACT

PURPOSE: To investigate the prognostic factors and effectiveness of postoperative radiotherapy alone for endometrial carcinoma. MATERIALS AND METHODS: Sixty four patients with stage I-III endometrial cancer (EC) treated with postoperative radiotherapy alone between January 1989 and December 2008 at the Keimyung University Dongsan Medical Center were chosen for the present study. Typically, total hysterectomy, salpingo-oophorectomy and lymphadenectomy were performed on the patient's pelvis. Total dose from 50.4 Gy to 63 Gy was irradiated at pelvis or extended field. Thirteen patients were treated with Co-60 or Ir-192 intracavitary radiotherapy. Follow-up periods were from 7 to 270 months, with a median of 56 months. RESULTS: Five year overall survival (OS) rate was 58.7%, respectively. Five year disease-free survival (DFS) rate was 59.2%, respectively. In univariate analysis for OS and DFS, stage, menopausal age, type of operation, serosal invasion, and lymph node involvement were found to be statistically significant. Histologic type was marginally significant. In multivariate analysis for OS and DFS, stage, types of operation, histologic type were also found to be statistically significant. Treatment failure occurred in 14 patients. The main pattern of failure was found to be distant metastasis. Time to distant metastasis was from 3 to 86 months (median, 12 months). There were no grade 3 or 4 complications. CONCLUSION: Stage, types of operation, and histologic type could be the predictive prognostic factors in patients. We contemplated postoperative radiation as effective and safe treatment method for EC. Additional treatment would be needed to reduce distant metastasis.

ABSTRACT

Se realizó una investigación retrospectiva y analítica, con el objetivo de identificar los factores de riesgo asociados a las lesiones endometriales en las mujeres obesas mayores de 50 años en el municipio Pinar del Río. El universo de estudio estuvo constituido por la totalidad de las mujeres residentes en el área de salud Hermanos Cruz. Se seleccionó un grupo de estudio conformado por las mujeres obesas mayores de 50 años y un grupo de control conformado por las mujeres mayores de 50 años no obesas. Para obtener los datos, se utilizó una encuesta-formulario, donde se incluyeron variables generales de la mujer, antecedentes personales y familiares e historia ginecobstétrica, la cual fue aplicada a ambos grupos, con previo consentimiento. Se realizó un estudio ultrasonográfico a las mujeres incluidas en la investigación y uno histológico del endometrio cuando el examen ultrasonográfico resultó anormal (mayor de 4 mm en posmenopáusicas y de 14 mm en premenopáusicas.). Se confeccionó una base de datos con las variables estudiadas. Los resultados obtenidos se agruparon en cuadros (simples y de contingencia). Para su procesamiento estadístico se utilizaron la frecuencia absoluta y porcentual, el estadígrafo Ji cuadrado, pruebas de probabilidad de Fisher, los odds ratio (crudo y ponderado) y Z. La obesidad estuvo asociada con mayor probabilidad de tener un resultado ultrasonográfico anormal de la medida del grosor endometrial y de lesiones premalignas y cáncer endometrial, principalmente cuando existieron antecedentes familiares de cáncer de mama o colon y antecedentes personales de menarquía precoz, paridad y sangrado uterino anormal.


A retrospective and analytic research was carried out with the purpose of identifying risk factors associated with endometrial lesions in obese women older than 50 years old in Pinar del Rio municipality. The universe was comprised of the total of women living at "Hermanos Cruz" health sector. A group of obese women older than 50 years old and a control group of non-obese women older than 50 years old were chosen. To collect data, a survey-form was used; including general variables of women, personal, familial, gynecological and obstetric records. The survey was applied for both groups having a previous consent. A sonographic study was conducted to women participating in the research and performing an endometrial-histological examination when the Sonography showed abnormalities (greater 4mm in postmenopausal and 14mm in premenopausal women). A database using the variables studied was created; and the results were grouped in charts (simple and of contingency). In the statistical process absolute frequency and percentage, chi square, Fisher's probability test, odds ratio (raw and adjusted), and Z test were used. Obesity was associated with a major probability of having an abnormal sonographic result of the endometrial thickness, premalignant lesions and endometrial cancer; mainly when familial history of breast or colon cancers existed as well as personal records of early menarche, parity and abnormal uterine bleeding.

ABSTRACT

Two innovative approaches in minimally invasive surgery that have been introduced recently are the da Vinci robotic platform and single port laparoscopic surgery (SPLS). Robotic surgery has many advantages such as 3-dimensional view, the wrist like motion of the robotic arm and ergonomically comfortable position for the surgeon. Numerous literatures have demonstrated the feasibility of robotic surgery in gynecologic oncology. However, further research should be performed to demonstrate the superiority of robotic surgery compared to conventional laparoscopy. Additionally, cost reduction of robotic surgery is needed to adopt robotic surgery into gynecologic oncology worldwide. SPLS has several possible benefits including reduced operative complications, reduced postoperative pain, and better cosmetic results compared to conventional laparoscopy. Although several authors have indicated that SPLS is a feasible approach for gynecologic surgery, there have been few reports demonstrating the potential advantages over conventional laparoscopy. Moreover, technical difficulties of SPLS still exist. Therefore, the advantages of a single port approach compared to conventional laparoscope should be evaluated with comparative study, and further technologic development for SPLS is also needed. These two progressive technologies take the lead in the development of MIS and further studies should be performed to evaluate the benefits of robot surgery and SPLS.

ABSTRACT

In order to investigate the role of the PTEN expression in carcinogenesis and develop-ment of endometrial carcinoma and clarify whether and how PTEN and PI3K/Akt pathway relate to endometrial carcinoma,the expression of PTEN and phospho-Akt was detected by semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) methods and Western-blot from 24 cases of endomctrial carcinoma,10 cases of endometrial atypical hyperplasia,10 cases of endometrial hy-perplasia,and 10 cases of normal endometrium.SP immunohistochemical methods were used to measure levels of PTEN protein expression in following 5 study groups:31 cases of endometrium in proliferative phase,30 cases of endometrium in secretory phase,71 cases of endometrial hyperplasia,25 cases of atypical hyperplasia and 73 cases of endometrial carcinoma.Immunostaining score of PTEN was 3.39±0.15 in proliferative phase,1.90±0.21 in secretory phase,3.34~0.29 in endometrial hyperplasia,0.624±0.11 in atypical hyperplasia,and 0.74±0.19 in endometrial carcinoma,respectively.PTEN mRNA relative value in normal endometrium,endometrial hyperplasia,endometrial atypical hyperplasia,and endometrial carcinoma was 2.45±0.51,2.32±0.32,0.46±0.11,and 0.35±0.13 respec-tively.The expression levels of PTEN mRNA and protein in patients with endometrial carcinoma and atypical hyperplasia were significantly lower than in those of proliferative phase and with endo-metrial hyperplasia.The level of PTEN expression in patients with endometrial carcinoma was sig-nificantly related to tissue type (P<0.005),differentiation (P<0.05) and clinical stage (P<0.05),but not to depth of myometrium invasion (P>0.05).Western blot analysis revealed that Phospho-Akt level in PTEN negative cases was significantly higher,and there was a negative correlation between PTEN and phospho-Akt (r=- 0.8973,P<0.0001).It was suggested that loss of PTEN expression was an early event in endometrial tumorigenesis.The phosphorylation of Akt induced by the loss of PTEN took part in the tumorigenesis and development of endometrial carcinoma.
