Trucut biopsy of breast lesions: the first step toward international standards in developing countries. Eur J Cancer 2012; 48:648-54. [PMID: 22244803 DOI: 10.1016/j.ejca.2011.11.038] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2011] [Revised: 10/15/2011] [Accepted: 11/18/2011] [Indexed: 11/26/2022]
Abstract
UNLABELLED The new concept in breast cancer diagnosis and treatment is based on a less invasive, more accurate and effective strategy, with a multidisciplinary approach in a specialised breast unit. When indicated, conservative surgery has replaced mastectomy with sentinel-node biopsy substituting routine axillary dissection. But the key factor in respect of these new standards is to confirm the cancer before going to the operating room. Trucut biopsy is performed instead of incisional or excisional biopsy and frozen section. The technique is reliable, simple, and reproducible, and not at all expensive; it can be adapted even for low-income developing countries. MATERIALS AND METHODS Between March 2006 and June 2010, 764 patients under clinical suspicion of cancer and/or with BIRADS (Breast Imaging Reporting and Data System) III-V in imaging in one university and one private hospital in Tehran, Iran underwent trucut biopsy (60% palpable and 40% non-palpable lesions). Cancer was found in 30.8% of the cases. In benign pathology, in concordance with clinical and imaging suspicion, surgery was omitted with short-term follow-up. For palpable symptomatic benign lesions surgery was performed to relieve the patient's symptoms. When the pathology report was not in concordance with clinical/imaging suspicion (1.8%), and in the presence of moderate and severe hyperplasia with or without atypia, in lobular and papillary lesions (4.9%) open biopsy was done to rule out cancer (10 added cancers, 1.3%; total cancers 32.1%). Cancer surgery was done as a single procedure in 89.8% of cases. CONCLUSION Trucut biopsy for breast lesion assessment is the first step toward a new concept in breast cancer care. It is simple, reduces the number of surgeries (no surgery for non-symptomatic benign lesions and one surgery for cancer), and avoids diagnostic errors with full respect for the patient's rights. We insist on its routine use to extend international guidelines while decreasing the total cost of this common disease in all low-resource countries.

Abstract
Core biopsy (CB) has now largely replaced fine-needle aspiration cytology (FNAC) in the preoperative assessment of breast cancer in the UK. We studied the contribution of FNAC and CB in the preoperative diagnosis of screen-detected breast carcinoma. Data were prospectively collected on 150 840 women who underwent breast screening over a 4-year period from 1999 to 2003. Data on women who had both FNAC and CB taken from the same lesion preoperatively and in whom surgical excision of the lesion subsequently confirmed malignancy was analysed. In 763 cancers, FNAC was inadequate (C1) in 8% and benign (C2) in 10%. Most of these cases presented with microcalcification (25% were C1 or C2). Core biopsy was not representative (B1) or benign (B2) in 7%. The absolute and complete sensitivities were 65 and 82% for FNAC and 80 and 93% for CB in the diagnosis of cancer. Core biopsy was abnormal (B3 or above) in 86% of the cancers missed by FNAC and FNAC was abnormal (C3 or above) in 65% of those missed by CB. Core biopsy is better than FNAC at preoperative diagnosis of screen-detected breast cancer as it missed fewer cancers. However, combining FNAC resulted in a better preoperative diagnosis rate.

Abstract
Evidence suggests that in experienced hands fine needle aspiration biopsy (FNAB) is highly safe and effective for the evaluation of patients who have palpable breast lesions. In most cases, FNAB leads to an appropriate clinical or surgical management. FNAB can also be effectively used in evaluation of cystic lesions under ultrasound guidance. Other nonpalpable lesions can benefit from image-directed core needle biopsy (CNB). Overall, cost should influence the decision to use FNAB or CNB. FNAB may be the only affordable procedure in developing countries. Breast cancer affects significant numbers of women worldwide. Attempts should be made to take all the measures necessary to consider optimal approaches to breast health care for everyone regardless of age, race, ethnicity, or social status.

Abstract
INTRODUCTION Core biopsy (CB) has now largely replaced fine needle aspiration cytology (FNAC) in the pre-operative assessment of breast cancer. We studied the contribution of FNAC, when done as an adjunct to CB, in cancer patients presenting symptomatically. PATIENTS 112 patients had both CB and FNAC pre-operatively and subsequently had surgery (wide local excision or mastectomy). CB & FNAC were done clinically in half the patients and under ultrasound guidance in the majority of others. RESULTS The complete sensitivity of FNAC was 90% and that of CB was 99%. Absolute sensitivity was 67% and 94%, respectively. CB was not suspicious of malignancy (B1) only in 1 patient in whom FNAC was suspicious (C3). In this patient there was a high degree of suspicion of breast cancer clinically & radiologically so a negative CB would not have been accepted even in the absence of FNAC. CONCLUSIONS FNAC, when performed in addition to CB, does not provide useful additional information in symptomatic breast cancer patients.

How stereotactic core-needle biopsy affected breast fine-needle aspiration utilization: An 11-year institutional review. Diagn Cytopathol 2004; 31:106-10.

Abstract
To determine the effect of stereotactic core-needle biopsy (SCNB) on the utilization of breast fine-needle aspirate (FNA) biopsy, we retrospectively reviewed 1,568 cases of breast FNAs that were obtained from 1,188 patients between the years 1990 and 2000. There were 378 positive and atypical cases and 497 negative and unsatisfactory cases in the pre-SCNB group (between 1990 and 1996; 7 years); and 225 positive and atypical cases and 468 negative and unsatisfactory cases in the post-SCNB group (between 1997 and 2000; 4 years). The average number of cases per year in the pre- and post-SCNB groups was 125 and 173, respectively. While the average positive/atypical cases per year in both groups remained relatively constant, the average negative/unsatisfactory cases per year were significantly increased in the post-SCNB group (117 in the post-SCNB vs. 71 in the pre-SCNB). The increase in this group was due to a true increase in the negative diagnoses, since unsatisfactory rate decreased in the post-SCNB group (12.6% in the post-SCNB vs. 9.3% in the pre-SCNB). The sensitivity, specificity, positive predictive value, and negative predictive value were 90%, 79%, 92%, and 82% in the pre-SCNB group and 93%, 86%, 91%, and 90% for the post-SCNB group, respectively. In conclusion, the implementation of SCNB did not result in a decrease in the total number of breast FNAs; however, the distribution of cases changed. FNA is increasingly used to complete the triple test in clinically and radiographically negative cases.

Abstract
Minimally invasive breast biopsy techniques, such as core needle biopsy (CNB) and fine-needle aspiration biopsy (FNAB), offer several advantages over surgical biopsy. Patients in whom minimally invasive biopsy techniques are used may undergo biopsy more quickly, are more likely to have only one surgery for treatment of the breast tumor and axillary staging, and are less likely to need reoperation after breast-conserving surgery because of positive margins. Knowledge of a diagnosis of cancer before surgery allows patients to participate in treatment decisions, and compared with surgical biopsy, minimally invasive biopsy has lower costs, produces less scarring, has nearly equivalent diagnostic accuracy, and does not require general anesthesia or sedation. Minimally invasive biopsy can permit accurate diagnosis and prompt intervention in a cost-effective manner, particularly in countries with limited resources, where patients often present with advanced-stage breast cancer. Several events characterize the implementation of a successful program in minimally invasive breast biopsy: public education about the less invasive nature of these techniques, which may encourage women to seek care at earlier stages; a change in the philosophy of medical personnel that favors involving patients in treatment decisions and acceptance of less extensive but accurate methods of diagnosis; education of medical personnel in the selection of patients for minimally invasive biopsy, performance of the biopsy, and interpretation of histologic and/or cytologic samples; quality assessment and use of the triple test (i.e., correlation of clinical, radiologic, and pathologic findings); and economical use of resources, which results from the lower costs of minimally invasive procedures and the avoidance of unnecessary surgery for benign conditions.

Abstract
BACKGROUND Several arguments are used for choosing either fine-needle aspiration cytology (FNAC) or core needle biopsy (CNB) in the evaluation of breast lesions. Comparison of published data on both methods is complicated by differences in study design, calculations, and operator experience. The objective of this study was to make a direct comparison of both methods. METHODS In 286 breast lesions (cysts and microcalcifications without a soft tissue mass excluded), both ultrasound-guided FNAC and CNB were performed in the same session by the same operator. Histologic follow-up was collected, and for those lesions that were not excised the results of the most recent mammography was used. A combination of the findings of both FNAC and CNB were evaluated. RESULTS Core needle biopsy and FNAC do equally well for sensitivity (88% vs. 92%), positive predictive value for malignancy (99% vs. 100%), and inadequate rate (7% vs. 7%). However, statistical differences are found for the specificity (CNB, 90%; FNAC, 82%). In addition, differences are found in the positive predictive value of both suspicious (CNB, 100%; FNAC, 78%) and atypia (CNB, 80%; FNAC, 18%) and for the suspicious rate (CNB, 5%; FNAC, 13%) reflecting difficulties in interpreting some FNACs. Combining the findings of both FNAC and CNB results in an increase in absolute sensitivity, a decrease in the positive predictive value of atypia compared with FNAC and CNB per se, and a decrease in the inadequate rate for cancers. CONCLUSIONS For the lesions selected in this study, FNAC and CNB are comparable for most parameters, but CNB has a higher specificity and lower suspicious rate. Combining results of FNAC and CNB leads to an increase in absolute sensitivity without affecting specificity and a decrease in the inadequate rate for cancers.

Abstract
The adoption of preoperative diagnostic strategies involving fine needle aspiration cytology (FNAC) or core biopsy is well established, allowing the planning of operating lists and bed occupancy and patient involvement in therapeutic management. In addition to diagnosis, however, pathologists are increasingly being asked to provide pathological prognostic information from preoperative samples. This leader describes techniques for predicting prognosis and response to treatment on these specimens and some of the problems inherent in the determination of prognosis on small samples. For example, although histological grade can be assessed relatively reliably on either core or FNAC samples, the evaluation of tumour type (which includes an overall assessment of the architecture of a given tumour) may be less reliable on small preoperative samples. Other well recognised histological prognostic factors, such as vascular channel invasion or tumour size, cannot be determined accurately on small preoperative samples. For those patients who might benefit from neoadjuvant treatment, predicting the response to such treatments--for example, by the assessment of oestrogen receptor status--can readily be performed on either core biopsy or FNAC. In the future, other molecular markers such as C-erbB-2 might also prove beneficial in predicting response to newly developed treatments.

Abstract
Minimal access procedures have great potential for providing patients with equal, if not superior, forms of breast cancer diagnosis and treatment. Many of these procedures are in a process of evolution. The reliability of each method probably depends heavily on the training, ability, and experience of the operator. Surgeons should be aware of the advantages and pitfalls of these techniques and exercise caution during the initial phases of their learning experience.

Abstract
We retrospectively evaluated the accuracy of fine-needle aspiration cytology (FNAC) in nonpalpable breast lesions detected by imaging techniques between 1995-1997. A total number of 308 lesions was investigated: 273 had been studied by means of either FNAC obtained under ultrasound (175 cases) or stereotactic guidance (98 cases). The overall sensitivity rate was 87.8%; specificity was 95.3%; the positive predictive value was 76.6%; the negative predictive value was 97.8%. Our results confirm that FNAC is quite effective in the approach to patients with nonpalpable breast lesions. It is particularly accurate in diagnosing malignancy, although a lower yield may be encountered in tumor types producing a desmoplastic stroma (tubular carcinoma, infiltrating lobular carcinoma) or in noncomedonic in situ ductal carcinoma. Discrepancy between a suspicious cytology and a negative histology is more frequent with benign lesions usually because of sampling mistake or technically inadequate smears. In particular, when smears are adequate, FNAC safely assists in ruling out the malignant lesions.

Abstract
From January of 1990 to December of 1992, 6,954 consecutive cytologic breast fine-needle aspiration biopsies (FNAB) were performed at the Laboratory of Pathology of Sant'Anna Hospital in Turin. Of these cases 62% were solid nodes, 35% were cystic nodes, and 2.7% were nonpalpable breast lesions (stereotaxic or ultrasound guided FNAB). We verified 4,110 cases: 913 cases underwent surgery and 3,197 were evaluated clinically, and/or cytologically, and/or with mammography at least 1 yr after the first diagnosis, or checked with the database of the Tumor Registry of Turin. In our series the FNAB sensitivity was 94.6%, specificity was 99.9%, accuracy was 98.8%, inadequate samples were 6.4%, false-negative rate was 1.4%, and false-positive rate was 0.3%. Our results indicate that the use of cell block improves sensitivity (from 85.2 to 94.6%) and strongly reduces false-negative results (from 3.9 to 1.4%). We conclude that FNAB is a discriminant procedure to the surgical biopsy in cases with clinical, ultrasound, or mammographic low or intermediate suspect, contributing to allow a high malignant/benign surgical biopsy rate and to reduce the need for frozen section diagnosis and medical costs.

Abstract
BACKGROUND Several reports have compared the results of fine-needle aspiration and stereotactic core needle biopsy in nonpalpable breast lesions. In this study the authors describe a simple method to retrieve cytologic material from a core breast biopsy sample that provides the diagnosis within 1 hour of the procedure. METHODS Two hundred and eleven nonpalpable breast lesions were biopsied. Each core needle biopsy sample was placed in a mesh bag, and the bag and needle notch were washed in Cytolyt solution to obtain a monolayer using a commercial ThinPrep processor. The cytologic diagnoses were divided into four categories: benign, suspicious, malignant, and unsatisfactory, which then were compared with core needle biopsy results. RESULTS Cytology reports of 211 lesions were as follows: 169 lesions (80%) were benign, 16 lesions (7.6%) were suspicious, 11 lesions (5.2%) were malignant, and 15 lesions (7.1%) were unsatisfactory. Core needle biopsy showed 165 of 169 samples (98%) to be benign and 4 to be malignant. Of the 16 suspicious smears, 10 were invasive carcinoma, 2 were in situ lesions, 3 were hyperplasias, and 1 was fibrosis. Of the 11 malignant smears, 10 were confirmed on core needle biopsy and 1 was read as atypia on the first core needle biopsy sample and malignant on a second, separate, follow-up core needle biopsy. Of the 15 unsatisfactory samples, 14 were found to be benign and 1 was found to be malignant on a separate, follow-up core needle biopsy. CONCLUSIONS The core wash technique was 85% sensitive and 98% specific for malignancy. Only 7% of specimens were insufficient for diagnosis, and 93% of these were proven to be benign. This technique is useful for immediate (within 1 hour) diagnosis of breast lesions, alleviating patient anxiety and supplementing the diagnostic yield of the core biopsy.

Abstract
BACKGROUND There appears to be a growing movement in favor of core needle biopsy (CNB) over fine-needle aspiration (FNA) cytology in detecting breast carcinoma in women. The authors compared the sensitivity and specificity of these two methods in patients who presented to The University of Texas M. D. Anderson Cancer Center for evaluation of a palpable breast mass. METHODS One hundred and twenty-four women (mean age, 51 years; range, 28-86 years) with a clinically suspicious palpable mass (mean size, 4.4 cm; range, 1-12 cm) underwent concurrent FNA and CNB. For the FNA, an average of three needle passes were made. FNA was followed by three CNBs using the Bard Monopty needle. CNB samples were submitted for frozen section to determine adequacy, and an additional three cores were performed if the first batch was deemed inadequate. All patients ultimately had histologic confirmation of their neoplasms either by the core needle procedure or by definitive open surgical biopsy. Features of cases with discrepant diagnoses were examined in relation to tumor size and histologic type. RESULTS Specificity of both FNA and CNB was 100%. The sensitivity in detecting a malignant neoplasm was higher for FNA than for CNB (97.5% vs. 90%, P < 0.004). CONCLUSIONS In our experience, FNA of palpable breast lesions is a more sensitive method for the detection of carcinoma regardless of tumor type, size, or differentiation. Contrary to other reports, not only was FNA alone more sensitive than CNB alone, the addition of CNB to an already negative FNA failed to increase sensitivity in the detection of carcinoma. However, CNB did contribute to a more definitive diagnosis in some cases. The authors also found FNA to be more cost effective than CNB for palpable breast lesions when time and effort are taken into consideration. This reinforces the benefit of FNA over CNB in the detection of early stage breast carcinoma.

Abstract
The purpose of the present study was to determine the usefulness of core needle aspiration biopsy (CNAB) with an 18-gauge modified menghini needle in the preoperative evaluation of 145 palpable breast masses as the major indicator for definitive treatment by surgery. Of the 145 lesions histologically verified by surgery, 126 were diagnosed as carcinoma, of which 117 were correctly diagnosed by the needle biopsy (93%). CNAB showed a sensitivity of 90% in the diagnosis of breast malignancy and a specificity of 100%. The overall diagnostic accuracy was 91%. There were no false-positive results and after definitive diagnosis with the Menghini needle, a one-stage procedure without frozen sections could be performed for definitive treatment of breast carcinoma.

Abstract
Percutaneous biopsy of nonpalpable breast lesions can be performed using mammographic or ultrasound guidance. Stereotaxy is the only technique applicable to microcalcifications and very small masses. With few exceptions, discrete masses greater than 0.7-0.8 cm can be visualized on high-frequency sonograms. Because of the continuous real-time monitoring of the needle placement and of the sampling procedure, sonography has proved to be highly accurate and safe in experienced hands. In addition to depending on the accuracy of the radiologist in hitting the target and the accuracy of the cytopathologic diagnosis, the success of fine-needle aspiration biopsy depends on successful tissue extraction. The lack of significance of insufficient specimens and the importance of properly recording such results in the calculation of accuracy values for fine-needle aspiration biopsy are emphasized. On the other hand, confidence in a negative cytologic result (i.e., adequate specimen without malignant cells) of a perfectly guided procedure is a prerequisite for the nonsurgical management of nonpalpable breast masses and thus for reducing the number of surgical biopsies.
