Phyllodes Tumor of the Breast: 307 Treated Cases, the Largest Mexican Experience at a Single Breast Disease Institution.

BACKGROUND: Phyllodes tumor (PT) of the breast in Hispanic patients is more frequently reported with large tumors and with more borderline/malignant subtypes compared with other populations. The objective of this study was to describe characteristics of patients with PT and to identify differences among subtypes in a Mexican population. METHODS: A retrospective study was conducted on patients with PT. Sociodemographic, histopathologic, and treatment characteristics were compared among subtypes, including only surgically treated cases due the complete surgical-specimen study requirement for appropriate WHO classification. RESULTS: During 10 years, 346 PT were diagnosed; only 307 were included (305 patients), with a mean age of 41.7 yr. Self-detected lump took place in 91.8%, usually discovered 6 months previously, with median tumor size of 4.5 cm. Local wide excisions were done in 213 (69.8%) and mastectomies in 92 (30.1%). Immediate breast reconstruction took place in 38% and oncoplastic procedures in 23%. PT were classified as benign in 222 (72.3%) cases, borderline in 50 (16.2%), and malignant in 35 (11.4%), with pathological tumor size of 4.2, 5.4, and 8.7 cm, respectively (P<0.001). Patients with malignant PT were older (48 yr), with more diabetics (14.3%), less breastfeeding (37.1%), more smokers (17.1%), with more postmenopausal cases (42.9%), and older age at menopause (51.5 years) compared with the remaining subtypes (P<0.05). Relapse occurred in 8.2% of patients with follow-up. CONCLUSION: In comparison with other Hispanic publications, these Mexican patients had similar age, with smaller tumors, modestly higher benign PT, fewer malignant PT, and lower documented relapse cases.

Enfermedad de Paget extensa de la vulva: Presentación de un caso y propuesta de manejo conservador / Extensive Paget's disease of the vulva: Case report and a conservative management proposal

La enfermedad de Paget extramamaria (EPE) es una patología maligna observada, sobre todo, en áreas donde existe alta densidad de glándulas apocrinas. Presentamos el caso clínico de una paciente de 68 años de edad, atendida en la Clínica de Colposcopia del Servicio de Oncología, del Instituto Nacional de Perinatología Isidro Espinosa de los Reyes, con diagnóstico de enfermedad de Paget a nivel vulvar, vagina, región de periné y región perianal, manejada con sesiones de vaporización con láser, con evolución satisfactoria. Dado que es una enfermedad poco frecuente, más común en el sexo femenino y en la raza blanca, con mayor incidencia en la séptima década de la vida, como es el caso de nuestra paciente, el objetivo de este trabajo es presentar una revisión de la evaluación clínica, haciendo énfasis en el diagnóstico diferencial, uso de colposcopia para diagnóstico y tratamiento conservador fraccionado con vaporización de láser. La baja incidencia de la enfermedad de Paget de la vulva, vagina, periné y región perianal, así como la ausencia de informes sobre la posibilidad de tratamiento no quirúrgico, motivan a informar a la comunidad científica sobre el manejo con vaporización láser, con la intención de evitar la morbilidad que puede traer consigo el manejo quirúrgico convencional.

Extramammary Paget's disease (EPD) is a malignant disease observed, especially in areas with high density of apocrine glands. We report a case of a patient of 68 years old, attended at the Colposcopy Clinic of Oncology, National Institute of Perinatology Isidro Espinosa de los Reyes, diagnosed with Paget's disease of the vulva, vagina, perineum region and perianal region, and managed with laser vaporization sessions with satisfactory outcome. Since it is a rare disease, more common in females and in whites, with the highest incidence in the seventh decade of life, as is the case of our patient, propose in this paper to present a review of the clinical evaluation with emphasis on the differential diagnosis, use of colposcopy for diagnosis and dividing up conservative treatment with laser vaporization of the disease. The low incidence of Paget's disease of the vulva, vagina, perineum and perianal region, and the absence of reports on the possibility of nonsurgical treatment encouraged to inform the scientific community about the management with laser vaporization, with the intention of avoiding morbidity that can lead to the conventional surgical maneuvers.

Tumor phyllodes / Phyllodes tumours

El tumor phyllodes es una neoplasia fibroepitelial rara; constituye el 0.3 al 0.9% de tumores de mama y 2-3% de los tumores fibroepiteliales de mama. Puede presentarse a cualquier edad y no hay características confiables para predecir su comportamiento clínico. Se deben evaluar varios parámetros, incluyendo la celularidad estromal, atipia, mitosis, crecimiento estromal excesivo, infiltración de bordes y presencia o ausencia de necrosis. La mayor parte de estos tumores son benignos, pero hasta 30% pueden presentar tejido conectivo maligno. Las metástasis generalmente son hematógenas más que linfáticas y se presentan en un 13% de los casos. La disección de ganglios axilares generalmente no se recomienda. El tumor phyllodes benigno y maligno recurre de manera local en el 25%, por lo que se recomienda el seguimiento de los casos.

Phyllodes tumors is a rare fibroepithelial neoplasm; constitute about 0.3-0.9% of breast tumors and 2-3% of fibroepithelial breast tumors. They usually occur in middle-aged to elderly women but can occur at any age. No single feature is reliable to predict clinical behavior of phyllodes tumors. Several histological parameters should be evaluated, including stromal cellularity, atypia, mitoses, stromal overgrowth, infiltrative borders, and presence or absence of necrosis. Most of these tumors are benign, but up to 30% show malignant stroma. Metastases usually are hematogenous rather than lymphatic have been reported to occur at a rate of 13% as malignant phyllodes tumors usually spread by a hematogenous rather than a lymphatic route; axillary lymph node dissection is generally not recommended. The benign and malignant tumors phyllodes resort locally in 25% and follow up of patients is recomended.

[Third National Ovarian Consensus. 2011. Grupo de Investigación en Cáncer de Ovario y Tumores Ginecológicos de México "GICOM"]. / Tercer Consenso Nacional de Cáncer de Ovario 2011. Grupo de Investigación en Cáncer de Ovario y Tumores Ginecológicos de México "GICOM".

INTRODUCTION: Ovarian cancer (OC) is the third most common gynecologic malignancy worldwide. Most of cases it is of epithelial origin. At the present time there is not a standardized screening method, which makes difficult the early diagnosis. The 5-year survival is 90% for early stages, however most cases present at advanced stages, which have a 5-year survival of only 5-20%. GICOM collaborative group, under the auspice of different institutions, have made the following consensus in order to make recommendations for the diagnosis and management regarding to this neoplasia. MATERIAL AND METHODS: The following recommendations were made by independent professionals in the field of Gynecologic Oncology, questions and statements were based on a comprehensive and systematic review of literature. It took place in the context of a meeting of two days in which a debate was held. These statements are the conclusions reached by agreement of the participant members. RESULTS: No screening method is recommended at the time for the detection of early lesions of ovarian cancer in general population. Staging is surgical, according to FIGO. In regards to the pre-surgery evaluation of the patient, it is recommended to perform chest radiography and CT scan of abdomen and pelvis with IV contrast. According to the histopathology of the tumor, in order to consider it as borderline, the minimum percentage of proliferative component must be 10% of tumor's surface. The recommended standardized treatment includes primary surgery for diagnosis, staging and cytoreduction, followed by adjuvant chemotherapy Surgery must be performed by an Oncologist Gynecologist or an Oncologist Surgeon because inadequate surgery performed by another specialist has been reported in 75% of cases. In regards to surgery it is recommended to perform total omentectomy since subclinic metastasis have been documented in 10-30% of all cases, and systematic limphadenectomy, necessary to be able to obtain an adequate surgical staging. Fertility-sparing surgery will be performed in certain cases, the procedure should include a detailed inspection of the contralateral ovary and also negative for malignancy omentum and ovary biopsy. Until now, laparoscopy for diagnostic-staging surgery is not well known as a recommended method. The recommended chemotherapy is based on platin and taxanes for 6 cycles, except in Stage IA, IB and grade 1, which have a good prognosis. In advanced stages, primary cytoreduction is recommended as initial treatment. Minimal invasion surgery is not a recommended procedure for the treatment of advanced ovarian cancer. Radiotherapy can be used to palliate symptoms. Follow up of the patients every 2-4 months for 2 years, every 3-6 months for 3 years and anually after the 5th year is recommended. Evaluation of quality of life of the patient must be done periodically. CONCLUSIONS: In the present, there is not a standardized screening method. Diagnosis in early stages means a better survival. Standardized treatment includes primary surgery with the objective to perform an optimal cytoreduction followed by chemotherapy Treatment must be individualized according to each patient. Radiotherapy can be indicated to palliate symptoms.

Preeclampsia-eclampsia: experiencia en el Centro Médico Nacional de Torreón / preeclampsia-eclampsia: experience in Centro Médico Nacional de Torreón

Objetivo. Analizar las características epidemiológicas y morbilidad materna y perinatal de las pacientes con preeclampsia atendidas en el Centro Médico Nacional Torreón, del IMSS. Material y método. Se realizó una encuesta retrospectiva y descriptiva de 138 ingresos al servicio de Ginecología y Obstetricia del 1§. de enero al 31 de diciembre de 1997 con diagnóstico de preeclampsia según los criterios del ACOG. Se determinaron las complicaciones maternas y perinatales secundarias a esta patología. También se calculó la tasa de mortalidad, letalidad y mortalidad proporcional. Para el análisis se empleó estadística descriptiva. Resultados. La prevalencia de preeclampsia fue de 2.1 por ciento,. La edad de las pacientes fue de 23.2 años (D.E. 3.05) y la edad gestacional al momento del diagnóstico de preeclampsia de 36.4 semanas (D.E. 3.2). Sólo 41.3 por ciento de las pacientes recibió control prenatal adecuado. La prevalencia de complicaciones maternas fue de 29.0 por ciento. La tasa de mortalidad fue de 0.15 x 1,000; la tasa de letalidad de 0.72 por ciento. El peso promedio de los neonatos fue de 2.011 kg (D.E. 0.429), el Apgar al primer minuto de 7.72 (D.E. 0.98) y de 8.66 (D.E. 1.10) al quinto minuto. La prevalencia de complicaciones perinatales fue de 35.5 por ciento. Se registraron 15 muertes neonatales (10.9 por ciento) y una fetal. Conclusiones. La preeclampsia-eclampsia sigue siendo una de las patologías que más inciden en la morbilidad y mortalidad materna y perinatal, por lo que se deberá seguir trabajando en encontrar la forma de prevenir su aparición o de modificar su evolución evitando la eclampsia u otras formas graves de la enfermedad.
