This poster aims to discuss the choice of biopsy site in patients with multiple oncologic lesions, comparing the diagnostic and complications rate for pulmonary versus non-pulmonary target sites. We chose the lung as a reference site, to which we compared all other sites, because the lung is a preferred metastasis location [1], the lung biopsy is one of the most studied procedures [2,3,4] and because the most frequent request in our interventional radiology department regarding imaging-guided procedures concerns the lungs.

We performed a retrospective study, on a lot of 350 consecutive patients with oncologic lesions, of which at least one located in the lungs, that underwent imaging-guided biopsies in our service between 2015 and 2018. In agreement with our hospital policy, the explicit consent requirement was waived. All patients were accepted for the procedures only if they were not on current oral anticoagulant treatment and their INR was below 1,5. In patients with glycemia values above 200 mg/dl, antibiotic drugs were administered. All procedures were...

The study group consisted of 91 women (26%) and 259 men (74%). The mean age of the group was 65, with ages ranging from 29 to 92 years old. Our study sample included 317 lung procedures and 47 non-lung procedures. The non-lung procedures included 23 bone (Fig. 1), 12 hepatic (Fig. 2), 7 small parts (muscle) (Fig. 3), 2 lymph nodes (Fig. 4), 2 mediastinal (Fig. 5) and 1 adrenal (Fig. 6) procedures. One patient had to undergo multiple-site procedures due to uncertainty regarding the...

As it would seem, when managing patients with multiple-site oncologic lesions, given adequate pre-procedural selection of patients, most complications occur when performing lung biopsies. Thus, even though the patient could present to the hospital with symptoms due to a lung lesion, or be primarily diagnosed with a lung lesion, hence referred for a lung biopsy, it is an interventional radiologist’s duty to check for other simultaneous lesions, that could offer the same amount of information for a lower complication rate. One should however always consider...
