The Gleason histologic score of prostatic adenocarcinoma in biopsy specimens (needle cores or transurethral chips) was compared with the Gleason score of corresponding radical prostatectomy specimens from 53 patients with localized prostatic carcinoma. The Gleason score assigned to the biopsy specimen was identical to that of the prostatectomy specimen in 51% of cases, was greater than that of the prostatectomy specimen in 4%, and was less than that of the prostatectomy specimen in 45%. The magnitude of discrepancy between the scores of the biopsy specimen and the prostatectomy specimen was directly related to the quantity of neoplastic tissue in the biopsy specimen. Discrepancies between the Gleason score of biopsy material and prostatectomy specimens were greater among biopsy specimens with low Gleason scores as compared with biopsy specimens with high Gleason scores. Given the small number of cases, these differences were not statistically significant. Clinical understaging of the primary tumor did not correlate with histologic undergrading of the prostatectomy specimen. It was concluded that prostatic biopsy should be repeated when the initial diagnosis of adenocarcinoma is based on only limited quantities of neoplastic tissue with a low Gleason score and management decisions may be influenced by the true Gleason score of the tumor.  相似文献

Ninety-five percent (195) of 203 fine needle aspiration biopsies (FNAB) of head and neck specimens contained adequate tissues for histologic evaluation. No complications or needle tract recurrences were identified. Out of 135 patients whose surgical excision followed FNAB, 5% (7/135) of the biopsies were nondiagnostic. Correlation of cytologic and histologic findings of the remaining 128 FNAB revealed a sensitivity rate of 82% (46/56), a specificity rate of 99% (71/72), and a positive predictive of value of 98% (46/47). The diagnostic accuracy of FNAB was better with salivary gland and cervical node specimens than with thyroid, skin, and subcutaneous specimens. Fine needle aspiration biopsy may be considered as the first diagnostic step in the evaluation of the mass of the head and neck region, if the nondiagnostic aspiration rate is low and the diagnostic accuracy is high.  相似文献

Accurate staging of patients with primary cutaneous melanoma includes assessment of regional lymph nodes for the presence of micrometastatic disease. Sentinel lymph node biopsy is highly accurate but is an invasive surgical procedure with a 5-10% complication rate, and requires labour-intensive and expensive histological examination to identify disease. A rapid, accurate and cost-effective non-surgical technique able to detect micrometastatic deposits of melanoma in regional lymph nodes would be of great benefit. Fine needle aspiration biopsies and tissue specimens were obtained from lymph nodes from 18 patients undergoing node resection for metastatic melanoma and five patients undergoing radical retropubic prostatectomy. One-dimensional proton magnetic resonance spectroscopy was undertaken at 360 MHz (8.5 T). Lymph nodes were cut into 3 mm thick slices and embedded. Four sequential 5 microm tissue sections were cut from each block and stained, with haematoxylin and eosin, for S100 protein, for HMB45, and again with haematoxylin and eosin, respectively. Proton magnetic resonance spectroscopy distinguished between benign and malignant lymph node tissue (P < 0.001, separate t-test) and benign and malignant lymph node fine needle aspiration biopsy (P < 0.012) based on the ratio of the integrals of resonances from lipid/other metabolites (1.8-2.5 p.p.m. region) and 'choline' (3.1-3.3 p.p.m. region). In conclusion, one-dimensional proton magnetic resonance spectroscopy on a simple fine needle aspiration biopsy can distinguish lymph nodes containing metastatic melanoma from uninvolved nodes, providing a rapid, accurate and cost-effective non-surgical technique to assess regional lymph nodes in patients with melanoma.  相似文献

An immunocytochemical assay for the estrogen receptor has been used to analyze the receptor content in tumor cells obtained by fine needle aspiration from human breast carcinomas. The results were compared with receptor determinations on cryostat sections of freshly frozen tumors and by biochemical technique based on radiolabelled ligand binding. The staining intensity and fraction of positive cells were comparable in cryostat sections and tumor cell specimens obtained by fine needle aspiration. Moreover, there was a good correlation between the semiquantitative receptor level estimated by the immunoperoxidase technique and the biochemical assay. These results show that tumor cell specimens obtained by fine needle aspirates can be used for estrogen receptor analysis by the immunocytochemical technique.  相似文献

Ovarian cancer specimens from 45 patients were assayed for the presence of estrogen receptor (ER) utilizing highly specific monoclonal antiestrophilin antibodies and the peroxidase-antiperoxidase technique. Results were compared with the conventional ER determination of the dextran charcoal method (DCC) and were in concordance in 91% of cases. This technique was also used to analyze ER in fine needle aspiration biopsy specimen from four patients with metastatic ovarian tumor. These results suggest that antireceptor monoclonal antibody in immunohistochemical analysis is an effective tool in the evaluation of estrogen receptor content in ovarian cancer. This technique can be easily performed at community hospitals and may be extended to the evaluation of fine needle aspiration biopsies and to analyze specimens of insufficient size for biochemical assay.  相似文献
