RESUMEN
Background: Patients with chronic lymphocytic leukemia (CLL) have a higher risk of developing other malignancies (OMs) compared to the general population. However, the impact of CLL-related risk factors and CLL-directed treatment is still unclear and represents the focus of this work. Methods: We conducted a retrospective international multicenter study to assess the incidence of OMs and detect potential risk factors in 19,705 patients with CLL, small lymphocytic lymphoma, or high-count CLL-like monoclonal B-cell lymphocytosis, diagnosed between 2000 and 2016. Data collection took place between October 2020 and March 2022. Findings: In 129,254 years of follow-up after CLL diagnosis, 3513 OMs were diagnosed (27.2 OMs/1000 person-years). The most common hematological OMs were Richter transformation, myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Non-melanoma skin (NMSC) and prostate cancers were the most common solid tumors (STs).The only predictor for MDS and AML development was treatment with fludarabine and cyclophosphamide with/without rituximab (FC ± R) (OR = 3.7; 95% CI = 2.79-4.91; p < 0.001). STs were more frequent in males and patients with unmutated immunoglobulin heavy variable genes (OR = 1.77; 95% CI = 1.49-2.11; p < 0.001/OR = 1.89; 95% CI = 1.6-2.24; p < 0.001).CLL-directed treatment was associated with non-melanoma skin and prostate cancers (OR = 1.8; 95% CI = 1.36-2.41; p < 0.001/OR = 2.11; 95% CI = 1.12-3.97; p = 0.021). In contrast, breast cancers were more frequent in untreated patients (OR = 0.17; 95% CI = 0.08-0.33; p < 0.001).Patients with CLL and an OM had inferior overall survival (OS) than those without. AML and MDS conferred the worst OS (p < 0.001). Interpretation: OMs in CLL impact on OS. Treatment for CLL increased the risk for AML/MDS, prostate cancer, and NMSC. FCR was associated with increased risk for AML/MDS. Funding: AbbVie, and EU/EFPIAInnovative Medicines Initiative Joint Undertaking HARMONY grant n° 116026.
RESUMEN
Resumen: La anestesia regional es la técnica de elección debida a la menor morbimortalidad. Una de las complicaciones más temidas es el hematoma espinal, teniendo las pacientes que reciben antiagregantes y/o anticoagulantes mayor riesgo de desarrollarlo. El cuadro clínico es variable, y no siempre están todos los elementos presentes (dolor lumbar, déficit motor y/o sensitivo y/o vesical). El diagnóstico se realiza por resonancia nuclear magnética y el tratamiento es la descompresión por laminectomía. Estando el pronóstico neurológico vinculado al tiempo en que se realiza ésta. Se realiza una revisión sobre los distintos fármacos antiagregantes y anticoagulantes utilizados en el embarazo - puerperio y las recomendaciones necesarias para las pacientes que recibirán una anestesia regional.
Abstract: Regional anesthesia is the technique of choice due to lower morbidity and mortality. One of the most feared complications is spinal hematoma, with patients receiving antiplatelet and / or anticoagulants having a greater risk of developing it. The clinical picture is variable, and not all the elements are always present (lumbar pain, motor and / or sensory and / or bladder deficits). Diagnosis is made by magnetic resonance imaging and treatment is laminectomy decompression. Being the neurological prognosis linked to the time in which it is performed. A review is made of the different antiplatelet and anticoagulant drugs used in pregnancy - puerperium and the necessary recommendations for patients who will receive regional anesthesia.
Resumo: A anestesia regional é a técnica de escolha devido à menor morbimortalidade. Uma das complicações mais temidas é o hematoma espinhal, com pacientes em uso de antiagregantes plaquetários e / ou anticoagulantes com maior risco de desenvolvê-lo. O quadro clínico é variável e nem sempre os elementos estão presentes (dor lombar, déficits motores e / ou sensoriais e / ou vesicais). O diagnóstico é feito por ressonância magnética e o tratamento é a descompressão por laminectomia. Sendo o prognóstico neurológico ligado ao tempo em que é realizado. É feita uma revisão das diferentes drogas antiplaquetárias e anticoagulantes utilizadas na gravidez - puerpério e as recomendações necessárias para as pacientes que receberão anestesia regional.
