CT and other radiological examinations are often used for assessment of possible spreading of different cancer types. For these examinations, it is possible to find enlarged lymph nodes or unspecific lesions where it is necessary to confirm or exclude metastases. If the lesion is visible on ultrasound, ultrasound-guided biopsy is the optimal method for clarification. The exception is for suspicion of sarcoma which should be adequately reported with pictures before sample collection. The indication assessment is done by a sarcoma specialist.
Ultrasound-guided biopsy is a quick method for diagnosing possible pathology of suspect lesions/changes deep in the abdomen. We always use fine-needle aspiration initially. The cell sample is stained immediately and assessed by a cytologist. In many cases, the diagnosis for metastasis or reactive lymph node is certain after rapid staining and microscopy. When relevant, a pistol biopsy is performed as well. In these cases, it is necessary to wait 4-6 days to initiate treatment while awaiting the result.
