Background: Hematological diagnoses with excisional biopsy in patients with adenopathies with suspected malignancy, generally entail a waiting period until the histological diagnosis that may interfere with the final prognosis of the patients. Shortening these waiting times, using specific techniques, can be a valid and safe alternative in selected patients. Ultrasound‐guided core biopsy techniques (trucut) could shorten these times, favoring the early initiation of treatments, and avoiding the adverse effects and consumption of health resources that imply a classic excision biopsy Aims: Main objective: to evaluate if ultrasound‐guided core biopsy for patients with malignant adenopathies reduces waiting times until the final diagnosis of the tumor disease. Secondary objectives are evaluated the adverse effects of the procedure, the efficiency of the same based on the adequate management of health resources and the satisfaction of patients with the technique evaluated by scales of quality of life Methods: We included patients with accessible adenopathies suspected of malignancy, evaluated by hematology in the period of Mar/Dec 2018.The data collected by anamnesis are: epidemiological (sex/age), anatomical region of the adenopathic conglomerate, waiting time (days) until the definitive diagnosis, the causes of inconclusive results and the adverse effects of the procedure. An economic evaluation of the health resources was made, based on the non‐request of consultations with other specialists(mainly anesthesia/surgery)and operating room time.All patients received an internal quality of life survey where satisfaction with the technique and subjective aspects related to waiting until diagnosis were evaluated.All data were compared with a historical cohort (2014/2017) for similar patients who had been studied by excisional biopsy in our hospital Results: 31 patients were included (corresponds to 49.6% of core biopsy of the total number of patients that required a biopsy).91% was cost‐effective(definitive histological diagnosis)and there was no need to resort to a new biopsy or to invasive procedures (excision surgery).The invalid samples (in which the diagnosis could not be confirmed) were 9%(n = 3)and the cause was by insufficient sample and in no case was due to a failure of the technique. The mean time (days) until the diagnosis was 8 days vs. 30 days,in the diagnoses by excision biopsy,according to the data reviewed by our center in the 2014/2017 period for
