The resuits indicte tht fine-needle spirtion iopsy cn e sustitute for open surgicl iopsy in selected cses. Introductìon It is well known tht comined clinicl, rdiologicl nd pthologicl study is the optiml procedure in one pthology [14]. Trditionlly, open surgicl iopsy hs een prerequisite for pthologicl dignosis. Since mny primry nd metsttic one tumors tend to e Iytic, dequte mteril cn often e otined y needle spirtion iopsy [4, 6-8, 10-12, 15, 18,20,22]. Yet severl uthors oject to the doption of needle iopsy techniques [I, 3, 9]. This study ws un dertken to demonstrte the fesiility nd role of fine-needle spirtion iopsy in the dignosis of mlignnt one tumors. The uthors wish to thnk Prof. Nicol Missi who mde this dignostic project possile. Mteril nd Methods This report is sed on the nlysis of 56 consecutive cses of mlignnt one tumors (15 primry nd 41 metsttic) studied from Jnury l, 1978, to Decemer 31, 1979. Figure 1 shows the sites of the spirtion iopsies. The method of co11ection nd preprtion of the cytologic specimens used in our lortory hs een outlined in detil elsewhere [18, 21). We would only like to point out tht we use n ordinry 22-guge spinl needle fitted with n oturtor with length vrying etween 25 nd 80 mm. Longer needles tend to end nd must never e used. On li occsions, spirtion hs een performed under TV fluoroscopic control, fter locl nesthesi, y tem composed of n orthopedic surgeon nd cytopthologist. With the needle dimeter we used, the trjectory of the needle does not hve to tke into considertion the locl ntomy, nd the shortest wy to puncture the lesion my thus e tken. Nevertheless, lrge lood vessels nd especi11y nerves must e voided (fig. 2-5).
Fine-Needle Aspirtion Biopsy in the Dignosis of Bone Mlignncies 77 We generlly work on smered mteril stined with My-Griìnwld-Giems nd Ppnicolou, which re complementry stins. Any residul mteril is further fixed in picric cid-lcohol, emedded in prffin s celi utton, step-sectioned nd stined with hemtoxylin-eosin. Results A sufficient quntity of cells hs lwys een otined y spirtion. Only twice ws it necessry to repet it ecuse sufficient cells were not ville. The dignosis ws sed 53 times on smers nd only 3 times on cell uttons. We dignosed mlignncies in li of the 56 cses; typing of the primry mlignnt one tumors hs een don e ccording to Hjdu nd Hjdu [7], while the celi typing of metstses followed the criteri estlished y Tkhshi [19] (tles I, II; fig. 2-5). No serious complictions were encountered; locl discomfort ws the only common complint. Tumor spreding through the needle trct ws not encountered nd, relying on other reports [2,5, 13, 17], we feel we cn exclude this possiility, while it is well known tht this does not hold true in respect of surgicl iopsies [1]. Fig. 1. Antomicl distriution of the lesions. Right: metstses; left: primry lesions. Discussion The purpose of open surgicl one iopsy is to otin mteril for histopthologicl exmintion in order to ssess the nture of the lesion prior to initition of definitive therpy [14]. Bone surgicl iopsy, usully incisionl iopsy, my led to contmintion of neighoring tissues y the tumor, requires generi nesthesi in most instnces, nd furthermore in some cses my e n elorte procedure (i.e., shoulder, pelvis, spine). More- over, one must relize tht tretment following tissue exmintion cn e quite different not only depending on whether the tumor is primry or metsttic tumor ut lso ccording to the kind of primry one tumor. Thus n incisionl iopsy my e too little or too much s fr s the susequent tretment (surgicl or nonsurgicl) is concerned. On the other hnd, the frozen-section technique, which my lso present technicl difficulties [16, 23] in this field of ppliction, requires surgicl iopsy thus shring with it the ove-mentioned limittions.

Fine-Needle Aspirtion Biopsy in the Dignosis of Bone Mlignncies 81 We would like to point out tht fine-needle spirtion iopsy cn e performed s n multory procedure, it is well ccepted y most ptients, cn e repeted if needed nd, ccording to our experience, it is prcticlly free of moridity nd mortlity s well s of ny risk of spreding the tumor. Cytologicl dignosis of mlignnt one tumors on mteril otined y needle iopsy is rel chllenge nd requires experience. It must never e regrded s sustitute for tissue exmintion ut, in selected instnces, it my yield meningful nd dependle informtion for therpeutic purposes.
