RESUMO
INTRODUCTION: Objective: the exact prevalence of obesity in Mexico is not well known and varies between sources, but more than 30% of Mexico's population are obese. Obesity is associated with several diseases such as metabolic syndrome; the latter, along with cancer, have become public health concerns worldwide, and their association has been widely studied in developed countries. The aim of this study was to identify the overall prevalence of metabolic syndrome and to describe its characteristics among first-time cancer patients at a referral center in Mexico. Methods: a prospective, observational, cohort study of first-time patients of the National Cancer Institute of Mexico in the period of September 2016-2017. We identified 1,165 first-time patients, and 316 patients with known or recently diagnosed metabolic syndrome were included. Results: median age was 55 years old and most were female (81%). The most frequent tumors were breast, gynecological, and hematological. Obesity (class 1-3) and abnormal glucose and/or previous diabetes mellitus diagnosis were mostly observed in patients with skin and soft tissue tumors; dyslipidemia, high triglycerides, and/or low HDL-cholesterol were mostly observed in patients with gastrointestinal tumors. Conclusion: the prevalence of metabolic syndrome among first-time cancer patients was 27%. As obesity and cancer are of public concern in Mexico, the implementation of preventive strategies for metabolic syndrome patients, focusing on the first level of care during early stages in order to reduce the risk of cancer, is needed.
INTRODUCCIÓN: Objetivo: la prevalencia de la obesidad en México es mayor del 30% de la población total. La obesidad se asocia con diversas enfermedades, entre ellas el síndrome metabólico; este y el cáncer se han convertido en problemas de salud pública a nivel mundial, y su asociación ha sido ampliamente estudiada en países desarrollados. El objetivo de este estudio fue identificar la prevalencia del síndrome metabólico y describir las características entre pacientes oncológicos de primera vez en un hospital de tercer nivel en México. Métodos: estudio prospectivo, observacional y de cohortes que incluye a pacientes oncológicos atendidos por primera vez en el Instituto Nacional de Cancerología durante el periodo de septiembre 2016 a 2017. Identificamos 1165 pacientes; 316 tenían el diagnóstico de síndrome metabólico y fueron incluidos en el presente estudio. Resultados: la mediana de edad fue de 55 años y la mayoría de los pacientes eran del sexo femenino (81%). Las neoplasias más frecuentes fueron las de mama, ginecológicas y hematológicas. La obesidad (clase 1-3) y la glucosa anormal y/o un diagnóstico previo de diabetes mellitus se observaron mayormente en pacientes con neoplasias de piel y tejidos blandos; los pacientes con neoplasias gastrointestinales presentaron mayormente dislipidemia, triglicéridos elevados y/o HDL bajo. Conclusiones: la prevalencia del síndrome metabólico en nuestros pacientes oncológicos fue de 27%. Al ser la obesidad y el cáncer problemas de salud pública en México, la implementación de medidas preventivas para pacientes con síndrome metabólico debe enfocarse en el primer nivel de atención, durante etapas tempranas, para poder reducir el riesgo de cáncer.

The epithelial ovarian cancer (EOC) has been underdiagnosed because it does not have a specific clinical presentation, and the signs and symptoms are similar to the irritable bowel syndrome and pelvic inflammatory disease. EOC is less common than breast and cervical cancer, but it is more lethal. On the whole, EOC has an early dissemination to peritoneal cavity, which delays a timely diagnosis and increases the rate of advanced diagnosed disease. The diagnosis usually surprises the women and the primary care physician. Therefore, it is necessary to count on prevention and early diagnosis programs. EOC has 80% response to surgical treatment, but nearly 70% of the patients may relapse in five years. The objectives of this document are presenting a summary of the EOC epidemiology and comment about advancements in prevention, diagnosis, and treatment of this cancer. That will raise awareness about the importance of this disease.

Resumen El cáncer ovárico epitelial (COE) ha sido subdiagnosticado debido a que no tiene presentación clínica específica y a que los signos y síntomas son similares al síndrome de colon irritable y a la enfermedad inflamatoria pélvica. Es menos común que el cáncer de mama o el cervicouterino, pero es más letal. En general, tiene diseminación temprana a cavidad peritoneal, lo cual retrasa un pronóstico oportuno e incrementa la tasa de diagnóstico de enfermedad avanzada. Usualmente, el diagnóstico sorprende a la mujer y al médico de primer contacto. Entonces, es necesario contar con programas de prevención y diagnóstico temprano. El COE tiene 80% de respuesta quirúrgica, pero cerca de 70% de las pacientes puede recaer en cinco años. Los objetivos de este documento son presentar un resumen de la epidemiología del COE y comentar los avances en prevención, diagnóstico y tratamiento de este cáncer. Esto despertará la conciencia acerca de la importancia de esta enfermedad.

We retrospectively reviewed the records of 100 patients with malignant disease and symptomatic pericardial effusion initially treated with pericardiocentesis at the National Cancer Institute of Mexico between 1985 and 2009. We analyzed predictive factors for recurrence of pericardial effusion by bi- and multivariate analyses. The group comprised 74 women and 26 men. Twenty patients had developed malignant pericardial effusion at the time of primary cancer diagnosis. Recurrence rate after pericardiocentesis was 33%. Progression-free survival for pericardial effusion at one year was 59% (range, 47-71%). Median overall survival (OS) after pericardiocentesis was 40.3+/-7.9 weeks (95% Confidence interval, 24.9-55.7). The sole factor that correlated with increased progression-free survival for pericardial effusion was the presence of bloody pericardial effusion. For OS, multivariate analysis yielded that female gender and presence of pericardial effusion at time of primary malignancy diagnosis were associated with higher life expectancy. Initial pericardiocentesis can provide successful management of patients with a control rate of 67%. In spite of the high effectiveness of the primary management of pericardial effusion with pericardiocentesis in oncologic patients, it might be considered for initial treatment, especially those with poor prognosis, leaving pericardial window as a secondary strategy for recurrence.
