Form of presentation, natural history and course of postoperative venous thromboembolism in patients operated on for pelvic and abdominal cancer. Analysis of the RIETE registry. / Forma de presentación, historia natural y evolución de la enfermedad tromboembólica venosa postoperatoria en pacientes operados por cáncer abdominal y pélvico. Análisis del registro RIETE.

INTRODUCTION: Venous thromboembolism (VTE) represents a serious complication after oncologic surgery. Recent studies have shown that the risk of VTE persists several weeks after surgery. This study assesses the form of presentation and time course of VTE after abdominal and pelvic cancer surgery. METHODS: Prospective, multicenter, observational study that analyzes data from an international registry (RIETE) that includes consecutive patients with symptomatic VTE. Our study assesses the form and time of presentation of postoperative VTE, as well as main outcomes, in patients operated for abdominopelvic cancer 8 weeks prior to VTE diagnosis. Variables related to the presentation of VTE after hospital discharge are identified. RESULTS: Out of the 766 analyzed patients with VTE, 395 (52%) presented pulmonary embolism (PE). Most VTE cases (84%) were detected after the first postoperative week, and 38% after one month. Among patients with VTE in the first postoperative week, 70% presented PE. VTE presented after hospital discharge in 54% of cases. Colorectal, urologic, and gynecologic tumors, the use of radiotherapy, and blood hemoglobin levels were independently associated with VTE diagnosis after hospital discharge. Complications (thrombosis recurrence, bleeding, and death) occurred in 34% of patients with VTE detected before hospital discharge, compared to 24% in VTE after hospital discharge (P<0.01). CONCLUSIONS: VTE occurs after hospital discharge in most patients, particularly in those operated for colorectal, urologic, and gynecologic cancer. Pulmonary embolism is more frequent in patients who develop early VTE, who also have worse prognosis.

Introducción: La enfermedad tromboembólica venosa (ETV) representa una grave complicación tras la cirugía oncológica. Recientes estudios revelan que el riesgo de ETV postoperatoria se extiende durante varias semanas. Este estudio analiza la forma y momento de presentación de la ETV tras cirugía oncológica abdominal. Métodos: Estudio observacional, prospectivo y multicéntrico, que analiza los datos de un registro internacional (RIETE) que incluye pacientes consecutivos con ETV sintomática. Se evalúa la forma y momento de presentación de la ETV, así como su pronóstico, en pacientes operados por cáncer abdominopélvico en las 8 semanas previas a la ETV. Se identifican las variables que se asocian con la presentación de la ETV tras el alta. Resultados: Entre los 766 pacientes analizados, 396 (52%) presentaron embolia pulmonar (EP). La mayoría (84%) de los casos de ETV se presentaron después de la primera semana de la intervención y un 38% pasado un mes. El 70% de los pacientes con ETV precoz presentaron EP. El 54% de los casos desarrollaron ETV tras el alta. Los tumores colorrectales y genitourinarios, el uso de radioterapia y los niveles de hemoglobina resultaron variables independientes de ETV tras el alta. El 34% de los pacientes con ETV antes del alta tuvieron complicaciones (recidiva, hemorragia y defunción), frente al 24% con ETV tras el alta (p < 0,01). Conclusiones: La ETV se presenta tras el alta en la mayoría de los pacientes, especialmente en aquellos con cáncer colorrectal y genitourinario. La EP es más frecuente en los pacientes con ETV precoz que, además, tienen peor pronóstico (AU)
