Factores de mal pronóstico en 113 pacientes sometidos a duodenopancreatectomía cefálica por colangiocarcinoma distal / Prognostic risk factors in 113 patients undergoing cephalic duodenopancreatectomy for distal cholangiocarcinoma

Introducción El colangiocarcinoma distal es una neoplasia epitelial maligna que afecta a los conductos biliares extrahepáticos, per debajo del conducto cístico. Existe poca evidencia sobre la relación entre factores perioperatorios y peor evolución a largo plazo tras la resección quirúrgica. Objetivo Analizar los factores de riesgo de mortalidad y recidiva a largo plazo del colangiocarcinoma distal de los pacientes resecados. Material y métodos Se ha analizado una base de datos prospectiva unicéntrica de pacientes intervenidos por colangiocarcinoma distal entre los años 1990 y 2021 con la finalidad de investigar los factores de mortalidad y recidiva. Resultados Se han intervenido 113 pacientes, con una supervivencia actuarial media de 100,2 (76-124) meses tras la resección. El estudio bivariante no evidenció diferencias entre los pacientes dependiendo de la edad o variables preoperatorias estudiadas. La presencia de adenopatías afectadas fue un factor de riesgo de mortalidad a largo plazo en el estudio multivariante. La presencia de adenopatías afectadas, la recidiva tumoral y la fístula biliar durante el postoperatorio implicaron peor supervivencia actuarial al comparar las curvas de Kaplan-Meier. Conclusiones La presencia de adenopatías afectadas influyen en el pronóstico de la enfermedad. La aparición de fístula biliar durante el postoperatorio del colangiocarcinoma distal podría agravar los resultados a largo plazo, hallazgo que debe ser reafirmado en futuros estudios. (AU)

Introduction Distal cholangiocarcinoma is a malignant epithelial neoplasia that affects the extrahepatic bile ducts, below the cystic duct. No relevant relationship between perioperative factors and worse long-term outcome has been proved. Objective To analyze the risk factors for mortality and long-term recurrence of distal cholangiocarcinoma in resected patients. Materials and methods A single-center prospective database of patients operated on for distal cholangiocarcinoma between 1990 and 2021 was analyzed in order to investigate mortality and recurrence factors. Results One hundred and thirteen patients have undergone surgery, with mean actuarial survival of 100.2 (76–124) months after resection. The bivariate study did not show differences between patients depending on age or preoperative variables studied. When multivariate analysis was performed, the presence of affected adenopathy was a risk factor for long-term mortality. The presence of affected lymph nodes, tumor recurrence, and biliary fistula during the postoperative period implied worse actuarial survival when comparing the Kaplan–Meier curves. Conclusions The presence of affected lymph nodes influence the prognosis of the disease. The occurrence of biliary fistula during postoperative cholangiocarcinoma distal could aggravate long-term outcomes, a finding that should be reaffirmed in future studies. (AU)

INTRODUCTION: Distal cholangiocarcinoma is a malignant epithelial neoplasia that affects the extrahepatic bile ducts, below the cystic duct. No relevant relationship between perioperative factors and worse long-term outcome has been proved. OBJECTIVE: To analyze the risk factors for mortality and long-term recurrence of distal cholangiocarcinoma in resected patients. MATERIALS AND METHODS: A single-center prospective database of patients operated on for distal cholangiocarcinoma between 1990 and 2021 was analyzed in order to investigate mortality and recurrence factors. RESULTS: One hundred and thirteen patients have undergone surgery, with mean actuarial survival of 100.2 (76-124) months after resection. The bivariate study did not show differences between patients depending on age or preoperative variables studied. When multivariate analysis was performed, the presence of affected adenopathy was a risk factor for long-term mortality. The presence of affected lymph nodes, tumor recurrence, and biliary fistula during the postoperative period implied worse actuarial survival when comparing the Kaplan-Meier curves. CONCLUSIONS: The presence of affected lymph nodes influence the prognosis of the disease. The occurrence of biliary fistula during postoperative cholangiocarcinoma distal could aggravate long-term outcomes, a finding that should be reaffirmed in future studies.

Carcinoma micropapilar infiltrante de la mama. Pronóstico a largo plazo / Invasive micropapillary carcinoma of the breast. Long term outcome

Introducción: el carcinoma micropapilar infiltrante (CMI) es una variante histológica inusual y potencialmente agresiva caracterizada por primera vez en 1993 por Siriangkul et al. y que no formó parte de la clasificación de la Organización Mundial de la Salud (OMS) hasta 2003, como tumor mamario epitelial. Representa menos del 2% del total de carcinomas invasivos de la mama y se presupone que presenta un pronóstico desfavorable en comparación con otros carcinomas convencionales debido a su elevado tropismo vascular y linfático. Material y métodos: hasta la fecha no existe ningún estudio con un número elevado de pacientes procedentes de un único centro (> 100 casos) con un periodo de seguimiento largo (> 20 años) que compare la supervivencia del CMI con otros carcinomas convencionales no micropapilares. Se ha llevado a cabo un estudio retrospectivo, observacional con un total de 401 pacientes: 174 con CMI y 227 con otros carcinomas convencionales. Resultados: el CMI presenta mayor grado histológico, mayor afectación ganglionar y mayor riesgo de metástasis a distancia en comparación con otros carcinomas convencionales de características similares. Sin embargo, en el análisis multivariante considerando factores pronósticos como edad, tamaño tumoral, afectación ganglionar y grado histológico, no se observan diferencias estadísticamente significativas para la supervivencia global y libre de enfermedad entre los CMI diagnosticados en el mismo periodo de tiempo que los casos pareados del grupo control y otros carcinomas convencionales. Conclusión: la supervivencia global y libre de enfermedad es similar entre el CMI y otros carcinomas convencionales a igual edad, tamaño tumoral, grado histológico y afectación ganglionar. (AU)

Introduction: Invasive Micropapillary Carcinoma of the breast (IMPC) is an unusual and aggressive histological variant characterized for the first time in 1993 by Siriangkul et al. and classified by the World Health Organization in 2003 as an epithelial breast tumor. It represents less than 2% of all invasive carcinomas of the breast and is presumed to have an unfavorable prognosis compared to other conventional carcinomas due to its high vascular and lymphatic tropism. Material and methods: Until now, there is no study with a large number of patients from a single center with a long follow-up period that compares the survival of IMPC with other conventional non-micropapillary carcinomas. A retrospective, observational study has been carried out with a total of 401 patients: 174 with IMPC and 227 with other conventional carcinomas. Results: IMPC has a higher histological grade, greater lymph node involvement and a higher risk of distant metastasis compared to other conventional carcinomas. However, in the multivariate analysis considering date of diagnosis, age, tumor size, lymph node involvement and histological grade as variables, no statistically significant differences were observed for overall and disease- free survival between IMPC and other conventional carcinomas. Conclusion: Overall and disease-free survival is similar between IMPC and other conventional carcinomas considering same age, tumor size, histological grade, and lymph node involvement. (AU)

STEMI, primary percutaneous coronary intervention and recovering of life expectancy: insights from the SurviSTEMI study.

INTRODUCTION AND OBJECTIVES: In the last few decades, there has been a continuous process of improvement in medical treatment and secondary prevention measures after ST-segment elevation myocardial infarction (STEMI). Patients older than 65 years are at increased risk of death due to this event. Our aim was to determine whether patients aged less than 65 years and 65 years and older experiencing a STEMI can recover a life expectancy similar to that of the general population of the same age, sex, and geographical region. METHODS: We included all patients experiencing a STEMI at our institution during a 6-year period in an observational-study (SurviSTEMI: survival in STEMI). We calculated their observed survival, expected survival, and excess mortality. We repeated all analyses for survivors of the acute event stratifying by 65 years. RESULTS: For patients aged <65 years who survived the STEMI, observed survival at 3 and 5 years of follow-up was 97.68% (95%CI, 96.05%-98.64%) and 94.14% (95%CI, 90.89%-96.25%), respectively. Expected survival at 3 and 5 years was 98.12% and 96.61%. For patients ≥ 65 years who survived the STEMI, observed survival at 3 and 5 years was 85.52% (95%CI, 82.23%-88.24%) and 75.43% (95%CI, 70.26%-79.83%), respectively. Expected survival at 3 and 5 years was 86.48% and 76.56%, respectively. CONCLUSIONS: For survivors of the acute event, life expectancy is fairly similar to that of the general population of the same age, sex, and geographical region.

Long-term prognosis after surgery for infective endocarditis: Distinction between predictors of early and late survival.

OBJECTIVES: Cardiac surgery is a life-saving procedure in patients diagnosed with infective endocarditis (IE). There are several validated risk scores developed to predict early-mortality; nevertheless, long-term survival has been less investigated. The aim of the present study is to analyze the impact of IE-specific risk factors for early and long-term mortality. METHODS: An observational retrospective study was conducted that included all patients who underwent surgery for IE from 2002 to 2016. Median follow-up time after surgery was 53.2 months (IQI 26.2-106.8 months). In-hospital mortality was analyzed using multiple logistic regression. Long-term survival was analyzed after one, two and five years. Cox proportional hazards regression was employed to identify risk factors related to long-term mortality. RESULTS: Of the 180 patients underwent cardiac surgery, 133 were discharged alive (in-hospital mortality was 26.11%). 6 variables were identified as independent factors associated with in-hospital mortality, most of them closely related to the severity of IE: age, multivalvular involvement, critical preoperative status, preoperative mechanical ventilation, abscess and thrombocytopenia. Long-term survival in patients discharged alive was 89.1%, 87.4% and 77.6% after one, two and five years. Long-term mortality was independent of specific IE factors and 86.51% of deaths were not related to cardiovascular or infectious diseases. CONCLUSION: Despite the high perioperative mortality rate after surgical treatment for active IE, long-term survival after hospital discharge was acceptable, regardless of the severity of the endocarditis episode. Although in-hospital survival depended mainly on several IE factors, long-term survival was not related to the severity of endocarditis baseline affection.
