ABSTRACT
Introducción y objetivo La acidosis metabólica (AM) es una alteración conocida en pacientes con derivaciones ileales. Es más frecuente en etapas tempranas postoperatorias y disminuye con el tiempo. Nuestro objetivo es determinar su prevalencia tras más de un año de seguimiento, analizar sus factores de riesgo y evaluar su impacto en diferentes perfiles metabólicos. Materiales y métodos Realizamos un estudio observacional entre enero de 2018 y septiembre de 2022 siguiendo las normas STROBE. La AM fue definida con valores de bicarbonato venoso <22mEq/l. Analizamos 133 pacientes con una media de seguimiento de 55,24±42,36 meses. Resultados Se identificaron 16 (12%) pacientes con AM. Los pacientes con y sin AM fueron comparables en edad, sexo y tiempo de seguimiento. El grupo con AM presentó una mayor tasa de anemia (68,75 vs. 19,65%; p<0,001) e insuficiencia renal (100 vs. 45,29%; p<0,001) y niveles venosos estadísticamente significativos mayores de creatinina, cloro, potasio, hormona paratiroidea y fósforo, pero menores valores de hemoglobina, filtrado glomerular, colesterol total, vitamina D, calcio y albúmina (todos p<0,05). El filtrado glomerular fue el único factor de riesgo independiente relacionado con la AM (OR: 0,914; IC 95%: 0,878-0,95; p<0,0001), demostrando una estrecha correlación con los valores de bicarbonato venoso (r=0,387; p<0,001). Conclusiones La AM es una alteración poco prevalente en derivaciones urinarias ileales transcurrido más de un año de la cistectomía, pero tiene implicaciones en el metabolismo hematológico, renal, proteico, lipídico y óseo. Aconsejamos su monitorización en pacientes con insuficiencia renal para poder realizar un diagnóstico y tratamientos precoces (AU)
Introduction and objective Metabolic acidosis (MA) is a well-known complication in patients with ileal urinary diversions. It is common in the early postoperative stages and decreases over time. Our objective is to investigate the prevalence of MA after more than one year of follow-up, identify the associated risk factors, and analyze its secondary metabolic consequences. Materials and methods We conducted an observational study between January 2018 and September 2022 following the STROBE guidelines. MA was defined as a serum bicarbonate level <22mEq/L. Finally, we analyzed 133 patients with a mean follow-up of 55.24±42.36 months. Results MA was observed in 16 (12%) patients. Patients with and without MA were comparable in age, sex, and follow-up time. The group with MA presented a higher rate of anemia (68,75% vs 19.65%, P<.001) and renal failure (100% vs 45.29%, P<.001), statistically significant higher levels of serum creatinine, chloride, potassium, parathyroid hormone, and phosphorus but lower serum values of hemoglobin, renal glomerular filtration rate, total cholesterol, vitamin D, calcium, and albumin (all P<.05). Renal glomerular filtration rate was the only independent risk factor related to the development of MA (OR: 0.914; 95% CI: 0.878-0.95; P<.0001), proving a close correlation with venous bicarbonate values (r=.387, P<.001). Conclusions MA is a little prevalent disorder in ileal urinary diversions more than one year after radical cystectomy is performed but it has secondary consequences on hematologic, renal, protein, lipid, and bone metabolism. We recommend to a close follow-up in patients with renal failure for early diagnosis and treatment (AU)

OBJETIVO: Evaluar la prevalencia de anemia preoperatoria y su impacto sobre los resultados oncológicos de pacientes intervenidos de cistectomía radical (CR) por tumor vesical. MATERIAL Y MÉTODOS: Estudio retrospectivo de 176 CR realizadas entre mayo de 2008 y julio de 2018 en un mismo centro. La anemia fue definida según los criterios de la OMS (hemoglobina < 130 mg/dl en hombres y < 120 mg/dl en mujeres). Mediante el método de Kaplan-Meier analizamos la supervivencia global, la supervivencia específica de cáncer y la supervivencia libre de recurrencia. Utilizamos la regresión logística multivariante para identificar los factores pronósticos de mortalidad global. RESULTADOS: Del total, 89 (50,6%) pacientes eran anémicos preoperatoriamente y 44 de ellos (49,4%) recibieron quimioterapia neoadyuvante. Los pacientes anémicos tuvieron un ASA mayor (ASA > 2: 54,6 vs. 27,5%, p = 0,003), más ectasia prequirúrgica (41,6 vs. 19,5%; p = 0,002), peor estadio patológico (pT > 2: 49,4 vs. 33,3%; p = 0,03), realizaron más quimioterapia neoadyuvante (49,4 vs. 19,5%; p < 0,001) y requirieron más transfusiones sanguíneas (25,8 vs. 11,5%; p = 0,015). La mediana de seguimiento fue de 27,2 meses (RIC 11,12-72,28). La supervivencia global (105 vs. 34 meses; p = 0,001), la supervivencia específica de cáncer (89 vs. 61 meses; p = 0,004) y la supervivencia libre de recurrencia (85 vs. 57 meses; p = 0,002) fueron peores en las CR anémicas. En el estudio multivariante, la anemia, un estadio pT > 2 y tener afectación ganglionar fueron identificados como factores predictores independientes de mortalidad. CONCLUSIÓN: La anemia previa a CR es común y asocia un peor pronóstico oncológico. Siendo esta una variable modificable, la implementación de programas de Patient Blood Management durante la prehabilitación puede tener un papel importante para mejorar la supervivencia de estos pacientes
OBJECTIVE: To evaluate the prevalence of preoperative anemia and its effect on oncological outcomes in patients undergoing radical cystectomy (RC) due to bladder cancer. MATERIAL AND METHODS: Retrospective single-center study with 176 RCs between May 2008 and July 2018. Anemia was defined according to the WHO classification (male < 130 mg/dL, female < 120 mg/dL). Kaplan-Meier test was used to estimate recurrence-free, cancer-specific and overall survival rates. Multivariate logistic regression was used to identify factors associated with overall mortality rates. RESULTS: Overall, 89 (50.6%) patients had preoperative anemia, and 44 of them (49.4%) received neoadjuvant chemotherapy. Anemic patients resulted in higher rates of ASA (ASA > 2: 54.6 vs. 27.5%; P = .003), ectasia rate previous to RC (41.6 vs. 19.5%; P = .002), treatment with neoadjuvant chemotherapy (49.4 vs. 19.5%; P < .001), blood transfusion rate (25.8 vs. 11.5%; P = .015) and pathological stage (pT > 2: 49.4 vs. 33.3%; P = .03) compared to non-anemic patients. Median follow-up was 27.2 months (IQR 11.12-72.28). Median overall survival (105 vs. 34 months, log-rank; P = .001), cancer-specific survival (89 vs. 61 months; P = .004) and recurrence-free survival (85 vs. 57 months; P = .002) were significantly lower in anemic patients compared to the non-anemic group. In multivariable Cox analysis, preoperative anemia, pT > 2 and N ≥ 1 were independently associated with overall mortality. CONCLUSION: Preoperative anemia was common in patients undergoing RC for bladder cancer, and it is related with a worse cancer prognosis. Anemia is a preoperative modifiable factor; we believe that the implementation of Patient Blood Management programs during prehabilitation may have a relevant role in improving the oncological outcomes in these patients

Purpose. Head and neck cancer is a highly heterogeneous disease comprising a large number of tumors located in the cervicofacial area. This study aimed to determine the epidemiological characteristics of squamous-cell carcinomas of the head and neck in the Spanish population, and the distribution of risk factors based on tumor locations. Methods/patients. A cohort of 459 patients (75 oral cavity, 167 oro-/hypopharyngeal and 217 laryngeal cancers) recruited in 19 hospitals participating in the Spanish head and neck cancer cooperative group were included over 3 years (2012-2014). Epidemiological parameters and risk factors were obtained from a self-administered questionnaire, and tumor characteristics were obtained from clinical records. Multivariate multinomial logistic regression was used to assess factors associated with tumor location. Results. Most patients were males (88.4 %), smokers (95 %) and drinkers (76.5 %). Relative to laryngeal cancer, pharyngeal cancer and oral cancer were more common in women than men (OR 3.58, p = 0.003 and 4.33, p = 0.001, respectively); pharyngeal cancer was more associated with rural environment (OR 1.81, p = 0.007) and weekly alcohol intake (10-140 g: OR 2.53, p = 0.012; 141-280 g: OR 2.47, p = 0.023; >280 g: OR 3.20, p = 0.001) and less associated with pack-years of smoking (21-40 packs: OR 0.46, p = 0.045; 41-70 packs: OR 0.43, p = 0.023; ≥71 packs: OR 3.20, p = 0.015). Conclusions. The distribution of these tumors differs between the sexes, with a higher proportion of oral cavity and pharyngeal tumors in women than in men. Oro-/hypopharyngeal cancers were more strongly associated with rural areas and with alcohol consumption, although less strongly associated with smoking than laryngeal tumors (AU)

Haemolytic uraemic syndrome (HUS) is a rare thromboembolic complication observed in patients with cancer. It is characterised by the clinical triad of acute renal failure, microangiopathic haemolytic anaemia and thrombocytopaenia. It may be associated with a variety of aetiologies, including chemotherapeutic agents such as mitomycin, cisplatin, bleomycin, 5-fluorouracil and, most recently, gemcitabine. We report a 70-year-old patient treated with gemcitabine who developed haemolytic uraemic syndrome (AU)
