ABSTRACT

Objetivos Determinar la frecuencia de los tumores primarios del sistema nervioso central, diagnosticados en Cartagena de Indias durante el periodo de 2001-2006 y, determinar las características demográficas, epidemiológicas y clínicas de los pacientes con tumores del sistema nervioso central de una institución de la ciudad, en el mismo periodo. Métodos Se realizó un estudio descriptivo de vigilancia epidemiológica pasiva. Se tomaron los reportes de patología con diagnóstico nuevo de tumor primario del sistema nervioso central de todos laboratorios de Cartagena y se analizaron las historias clínicas disponibles de estos casos. Se estimaron las tasas de incidencia general, por año, género, grupos de edad y tipo histológico con intervalos de confianza al 95 por ciento. Además se calcularon razones estandarizadas de morbilidad. Resultados Durante los años 2001 y 2006 se encontraron 390 casos. La tasa incidencia general fue de 6,91/100 000 personas-año. El tipo histológico más frecuente fue meningioma (3,46/100 000 personas-año). Sólo se determinó la procedencia en el 43,1 por ciento de los casos. Las razones estandarizadas de morbilidad fueron más altas en Cartagena con respecto a las de los Estados Unidos, el Instituto Nacional de Cancerología de Colombia y el Registro Poblacional de Cáncer de Cali. Conclusiones Hubo una frecuencia de tumores primarios del sistema nervioso central más elevada en Cartagena que en el resto del país. Se recomienda mejorar los sistemas de registro y vigilancia para determinar la magnitud real del problema y fomentar investigaciones en busca de factores de riesgo.


Objectives Determining the frequency of primary central nervous system tumours diagnosed in Cartagena; Colombia, from 2001-2006 and determining the demographic, epidemiological and clinical characteristics of patients having central nervous system tumours reported by a single institution in Cartagena between 2001 and 2006. Methods A passive epidemiological surveillance descriptive study was carried out. The pathology reports of new diagnosed central nervous system primary tumours from all laboratories in Cartagena were taken and the available clinical records regarding these cases were analysed. The overall incidence rate and incidence rates by year, gender, age and histological type were estimated, with 95 percent confidence intervals. Standardised morbidity rates were also calculated. Results There were 390 such cases during 2001-2006. The overall incidence rate was 6.91/100,000 people-year. Meningiomas were the most frequently occurring histological types (3.46/100,000 people-year). The provenance could only be determined in 43.1 percent of cases. Standardised morbidity rates were higher in Cartagena regarding those reported in the United States and by the Colombian National Cancer Institute and the Population-based Cali Cancer Registry. Conclusions There was a higher incidence of primary central nervous system tumours in Cartagena than in the rest of the country. Registry and surveillance systems should be improved and research into risk factors encouraged.

ABSTRACT

OBJECTIVE: To develop a model for pre-operative malignancy probability determination in a patient with an adnexal tumor or tumors by the application of multivariate logistic regression analysis to variables at the time of pelvic sonography. METHOD: Pre-operative ultrasound examination including Doppler analysis was performed on 117 consecutive women scheduled for surgery because of an adnexal mass or masses. Each tumor was classified as probably benign or malignant using a subjective evaluation system on the gray-scale morphological images. Then, Doppler sonography was carried out. The resistance index (RI) and pulsatility index (PI) of the vessel with the highest velocity were recorded. Multivariate logistic regression analysis was performed with the histological outcome as the dependent variable. Independent variables included patient's age, menopausal status, gray-scale morphological data, RI and PI. The probability of malignancy was formulated from statistical analysis. RESULTS: There were 117 women included in the study, 83 (71%) with histologically benign and 34 (29%) with histologically malignant ovarian tumors. Regression analysis on the five variables resulted in the retention of only patient's age, morphological data and RI as significant contributing factors for malignancy prediction. The probability of malignancy was 1/(1+e(-z)) where e was the base value for natural logarithms and z was the regression equation: -3.6355 + 1.8028 (age) + 2.1047 (morphological data) + 2.9816 (RI). CONCLUSION: A model for estimation of probability of malignancy for an adnexal tumor was derived using multivariate logistic regression analysis. The prediction should be more accurate than that from either gray-scale ultrasound imaging or Doppler velocimetry alone. The test of the model is now on-going.

ABSTRACT

Un total de 1039 tumores del mediastino se recopilaron de 12 Servicios, correspondieron a: timo 353 (34 por ciento), neurogénico 178 (17,2 por ciento), quistes 144 (13,9 por ciento), linfoma de mediastino 115 (11 por ciento), germinal 87 (8,4 por ciento), mesenquimático 63 (6,0 por ciento), endocrino 27 (2,6 por ciento) y varios 72 (6,9 por ciento). El 53,5 por ciento se ubicaron en mediastino anterior, el 39 por ciento fueron asintomáticos y 57 por ciento benignos o no invasores. Como método diagnóstico invasor la punción percutánea fue utilizada por 10 centros, 7 solamente ante tumores invasores, siendo los resultados buenos o muy buenos en 7. Ocho centros utilizaron mediastinoscopia, 12 mediastinotomía y 6 videotoracoscopia. La esternostomía mediana fue la vía de abordaje electiva en los tumores anteriores, y la toracotomía posterolateral en los tumores medios y posteriores. La videotoracoscopia terapéutica fue utilizada selectivamente en 9 centros, básicamente ante quistes y tumores benignos (< 6 cm). El timoma fue el tumor más frecuente del timo (327 casos); 10 centros adoptan la división en timoma no invasor-invasor utilizando la clasificación clínica de Masaoka. En 11 centros realizan solamente resección quirúrgica ante el timoma Estadio I, en todos tratamiento adyuvante en el estadio II y III. En 64/115 linfomas la variedad correspondió al Hodgkin. Ciento cuarenta y tres tumores neurogénicos fueron benignos (80,3 por ciento), el neurofibroma y neurolemona los más frecuentes. El 51,7 por ciento de los tumores germinales fueron malignos (45 casos), prevaleciendo entre ellos el seminoma y teratoma maduro. De 144 quistes, 63 fueron broncogénicos, hallándose 9 quistes hidatídicos. Las formas benignas y malignas de los mesenquimáticos se presentaron con igual frecuencia, el lipoma fue el tumor más frecuente. Se presentaron 23 bocios endotorácicos y 4 tumores paratiroideos

ABSTRACT

In the present study 32 extragonadal tumours, reported in 38 years (1956 to 1994) from the department of pathology, Kasturba Medical College, Mangalore were analysed. These were seen predominantly in infants and children mainly affecting females. The commonest sites of these tumours were sacrococcygeal region (46.88%) followed by retroperitoneum and mediastinum. The rarest sites were mesentery, fallopian tube and suprasellar region in the cranial cavity. Histologically 27 out of 32 cases were teratomas, 75% of which were benign.
