Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.

Prediction of pathological and oncological outcomes based on extended prostate biopsy results in patients with prostate cancer receiving radical prostatectomy: a single institution study. (6/60)

BACKGROUND: The prediction of pathological outcomes prior to surgery remains a challenging problem for the appropriate surgical indication of prostate cancer. This study was performed to identify preoperative values predictive of pathological and oncological outcomes based on standardized extended prostate biopsies with core histological results diagrammed/mapped in patients receiving radical prostatectomy for prostate cancer clinically diagnosed as localized or locally advanced disease. METHODS: In 124 patients with clinically localized or locally advanced prostate cancer (cT1c-cT3a) without prior treatment, pathological outcomes on the surgical specimen including seminal vesicle involvement (SVI), positive surgical margin (PSM), and perineural invasion (PNI) were studied in comparison with clinical parameters based on the results of 14-core prostate biopsies comprising sextant, laterally-directed sextant, and bilateral transition zone (TZ) sampling. RESULTS: Concerning the association of pathological outcomes with oncological outcomes, patients with PSM and PNI on surgical specimens had poorer biochemical-progression-free survival than those without PSM (logrank p = 0.002) and PNI (p = 0.003); it was also poorer concerning SVI, although the difference was not significant (p = 0.120). Concerning the impact of clinical parameters on these pathological outcomes, positive TZ and multiple positive biopsy cores in the prostatic middle were independent values predictive of SVI with multivariate analyses (p = 0.020 and p = 0.025, respectively); both positive TZ and multiple positive prostatic middle biopsies were associated with larger tumor volume (p < 0.001 in both). The percentage of positive biopsy cores (%positive cores) and biopsy Gleason score were independent values predictive of PSM (p = 0.001) and PNI (p = 0.001), respectively. Multiple positive cores in the prostatic base were associated with proximal/bladder-side PSM (p < 0.001), and also linked to poorer biochemical-progression-free survival (p = 0.004). Clinical T stage had no association with these pathological outcomes. CONCLUSIONS: %positive cores and Gleason score in extended biopsies were independent values predictive of PSM and PNI in prostate cancer clinically diagnosed as localized or locally advanced disease, respectively, which were associated with poorer oncological outcomes. When diagramming biopsy-core results, extended biopsy may provide additional information for predicting oncological and pathological outcomes including SVI in patients clinically diagnosed as having localized or locally advanced disease.

We retrospectively reviewed 87 consecutive EUS-FNB specimens using either a 22-gauge Franseen needle (Group A, N = 51) or a conventional 22-gauge fine-needle aspiration needle (Group B, N = 36) for pancreatic diseases, and the diagnostic accuracy and safety were compared. (hindawi.com)
There were no differences between the two needles in the locations from which the specimens were obtained. (hindawi.com)
Given its guaranteed ability to obtain core specimens and comparable safety, and although the risk of bleeding should be kept in mind, EUS-FNB using a Franseen needle is likely to become a standard procedure for obtaining pancreatic tissue in the near future. (hindawi.com)
However, grade concordance between the core needle biopsy of GS7miniGP4 and the corresponding radical prostatectomy (RP) specimens has not been studied. (nyu.edu)
In this study, we analyzed the pathologic features of 256 consecutive needle biopsies and their corresponding RP specimens. (nyu.edu)
Our data demonstrate that pathologic parameters in the RP are similar between the biopsy groups of GS7miniGP4 and GS6, and the grading of cases with biopsy GS7miniGP4 is often downgraded in RP specimens. (nyu.edu)
A total of 89 pairs of core needle biopsies and surgical specimens were collected, and the Ki-67 index was assessed in hot spot areas using an image analyzer. (ewha.ac.kr)
A significant difference in the Ki-67 index between core biopsy and surgical specimens was observed. (ewha.ac.kr)

If you aren't having the tumor removed, you may have a biopsy , which is a procedure to remove a small amount of tissue for testing. (medlineplus.gov)
The type of biopsy you have depends on the type of cancer you have and where the tumor is located. (medlineplus.gov)
At the same time, the active surveillance approach also recommends multiple biopsies to monitor the progression of the tumor. (anh-usa.org)
A 2004 study concluded that manipulation of an intact tumor, either by fine needle biopsy or by large-gauge needle core biopsy, is associated with an increase in metastases , perhaps due in part to the mechanical disruption of the tumor by the needle. (anh-usa.org)
A further biopsy in which more tissue is removed is always necessary just to make certain the tumor is cancer-free. (blackdoctor.org)
Ten of 22 cases of G7miniGP4 in the biopsies (45%) had pathologically insignificant tumor in the RP. (nyu.edu)
The quantity of GP4 in the GS7 biopsy significantly correlated with GS, pathologic stage, and total tumor volume in the corresponding RP. (nyu.edu)
Increased Ki67 expression by all evaluation methods was associated with aggressive tumor features (large tumor diameter, high histologic grade, ER negativity) and reduced patient survival. (uib.no)

Conclusion: The US-guided large needle core biopsy of axilla lesions is safe and effective for the pathological evaluation. (elsevier.com)
The core biopsy is believed to be easy to perform if suspicious lymph nodes or mass lesions are found in the axilla. (elsevier.com)
Therefore, the PET/CT will be evaluated for its diagnostic ability in lesions this size alone and in combination with a liquid biopsy. (stanford.edu)
Surgery to remove or biopsy breast lesions is relatively simple, not usually associated with great pain, and almost always done as an out-patient procedure, often under local anesthesia. (cochranfirm.com)
Other methods to evaluate mammogram-detected lesions include fine needle aspiration for cytologic analysis of the area in question, and the use of X-ray guided 'stereotactic' biopsy devices. (cochranfirm.com)
The performance of needle core biopsy (NCB) procedures for palpable breast lesions is currently considered the appropriate initial step in evaluating these abnormalities. (basicmedicalkey.com)
Ultrasound-guided core biopsies are usually performed for solid masses or complex cystic lesions. (basicmedicalkey.com)
MRI-guided biopsies are useful for lesions that are not detectable on clinical examination or on mammographic and ultrasonic evaluation. (basicmedicalkey.com)
Breast ultrasound may also be used to help doctors precisely guide a biopsy needle into some breast lesions. (hillmedical.com)
The Achieve biopsy system from BD gives you the precise control and quality sampling capability you need when working with calcified or fibrous lesions. (ciamedical.com)
Stereotactic breast needle biopsy refers to the sampling of nonpalpable or indistinct breast lesions by using techniques that enable the spatial localization of the lesion within the breast. (medscape.com)

Definitively diagnosing these lesions with needle biopsy has several advantages. (medscape.com)
Because most of the lesions detected during screening are impalpable, subsequent needle biopsy must be image-guided. (medscape.com)
Ultrasonography-guided biopsy is usually the most straightforward approach, but lesions better seen on mammography images, particularly microcalcifications, require stereotactic localization. (medscape.com)
