Needle Biopsy For Soft Tissue Tumors:

Biopsy is essential for accurate diagnosis to determine prognosis and treatment, and for malignant tumors to determine their staging. If possible, the histological type of the sarcoma can be determined. The design of treatment for sarcoma should take into account the characteristics of the local growth of the lesion, the probability of metastasis, and the most likely site of distant spread. It is important to obtain adequate specimens from appropriate sites for accurate diagnosis and staging of sarcoma. A limb mass is usually cut lengthwise, so it can be removed completely on biopsy. The optimal excision biopsy for most acromass is the simultaneous excision of a small amount of adjacent tissue. Partial excision biopsy should be avoided for tumors larger than 2cm in diameter, as this method may contaminate the surrounding tissue and lead to the eventual extension of excision. Deep tumor can adopt the method of center of tumor biopsy to determine the diagnosis, but limited samples may make it difficult to staging and predicting prognosis of d | learn education online collection. Fine needle aspiration (FNA) cytological diagnosis is best performed in a large case-volume and multidisciplinary unit, as this technique requires extensive experience and careful consultation with clinical radiologists to make an accurate diagnosis. The inevitable disadvantage of fine needle biopsy and FNA is the small specimen size, which not only affects correct diagnosis, but also histological classification and other auxiliary diagnostic techniques such as cytogenetics and electron microscopy.
