Testicular Fine-Needle Aspiration for Sperm Retrieval in Azoospermia: A Small Step toward the Technical Standardization. World J Mens Health 2019; 37:55-67. [PMID: 30584991 PMCID: PMC6305866 DOI: 10.5534/wjmh.180077] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2018] [Revised: 10/23/2018] [Accepted: 10/24/2018] [Indexed: 01/23/2023] Open
Abstract
PURPOSE The aim was to describe our preliminary experience performing testicular fine-needle aspiration (TEFNA) with a larger needle in infertile patients with obstructive azoospermia, and to provide a systematic literature review of the different testicular sperm aspiration techniques, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement recommendations. MATERIALS AND METHODS We prospectively collected data between March 2017 and June 2018. All men underwent bilateral TEFNA under analgo-sedation, using a larger disposable 18-gauge butterfly needle with 60 mL Luer-Lock syringe attached to it. RESULTS Thirty consecutive patients were enrolled. Median operative time was 16 minutes (interquartile range [IQR]: 12-30 minutes). No intraoperative complications occurred. Two/thirty patients (6.7%) reported postoperative adverse events: 1 patient had prolonged orchialgia, 1 patient presented scrotal hematoma. Successful sperm retrieval was found in 28/30 cases (93.3%). Median sperm concentration was 0.05 ×10⁶/mL (IQR: 0.001-0.1 ×10⁶/mL). Median total sperm motility was 10% (IQR: 0%-15%). In 20/30 men (66.7%) sperm retrieved was used for fresh intracytoplasmic sperm injection cycle, in 8/30 (26.7%) sperm cryopreservation was necessary, because on the day of sperm retrieval the female resulted not responder to ovarian stimulation. In this cases mean number of 3 (IQR: 1-4) bio system straws was cryopreserved. CONCLUSIONS TEFNA with 18-gauge needle proved to be a feasible, safe and effective treatment, even if future prospective studies will be addressed to clarify what type of azoospermia benefits from this procedure, and if a larger needle permits to improve Assisted Reproductive Technologies (ART) outcomes.

Does large needle aspiration biopsy add pain to the thyroid nodule evaluation? PLoS One 2013; 8:e58016. [PMID: 23536779 PMCID: PMC3594218 DOI: 10.1371/journal.pone.0058016] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2012] [Accepted: 01/30/2013] [Indexed: 11/19/2022] Open
Abstract
Thyroid large needle aspiration biopsy is disregarded because it is thought to be associated with pain. This is in contrast with our 32 years long experience. We surveyed reports of pain in patients examined with fine needle aspiration biopsy (78, 87.2% women, mean age 59 years) or FNAB+large needle aspiration biopsy (48, 87.5% women, mean age 60 years). Each patient was questioned regarding a) no unpleasant sensation (score "0"); b) unpleasant sensation ("1"); c) mild pain (no analgesic used; "2"); or d) pain (analgesic used; "3"). The mean size of the needle used was for FNAB 22.3±0.7 or 20.8±1 gauge in the fine needle aspiration or fine needle aspiration plus large needle aspiration biopsy group, respectively (p<.0001). The number of percutaneous punctures was higher in the fine needle aspiration plus large needle aspiration biopsy group. However, the pain score in the fine needle aspiration biopsy or fine needle aspiration biopsy plus large needle aspiration biopsy group was not significantly different. Large needle aspiration biopsy after fine needle aspiration biopsy does not add any discomfort or pain and therefore in light of the demonstrable benefits, should be included in clinical algorithms for the evaluation of thyroid nodules.

Abstract
A progressive increase in the incidence of thyroid cancer (TC) has been reported over the last few decades. This either reflects the increased number of newly discovered and accurately selected thyroid nodules with more sensitive technologies and a relative more potent carcinogenic effect of pathogenetic factors in malignant, but not benign nodules. This observational time-trend study addresses this issue by analysing the proportion of TC within 8411 consecutive thyroid nodule (TN) patients evaluated in Pisa by the same pathology Department and individual clinician over a four-decade period. From 1972 to 1979 surgery was used to detect TC among the TN patients: 1140 TN patients were operated on and 35 cancers were detected (3.1% of all the TN patients). Subsequently, needle aspiration techniques were used to select TN for surgery. From 1980 to 1992, 5403 TN patients were examined, 483 were selected for surgery, and 150 cancers were found (2.8% of all the TN patients). From 1993 to 2010, 1568 TN patients were examined, 143 were selected for surgery, and 46 cancers were found (2.9% of all the TN patients). Therefore, in the University Hospital of Pisa, and independent of preoperative TN selection protocols, these proportions of TN eventually found to harbor TC remained statistically unchanged over 40 years (p = 0.810). This finding suggests that pathogenic risk factors and more sensitive diagnostic technologies did not differentially affect the incidence of TN and TC.

Abstract
BACKGROUND Fine-needle aspiration biopsy (FNAB) is a simple technique for the investigation of suspicious thyroid nodules. However, low success rates are reported in the literature. The aim of this prospective study was to compare the clinical performance and impact of an automatic aspirator, referred to here as Aspirator 3, to those of the manual technique for the FNAB of clinically suspicious thyroid nodules. METHODS One hundred nine consecutive patients with 121 clinically suspicious thyroid nodules underwent a biopsy twice of the same site with the clinically approved Aspirator 3 and with the manual technique. The number of follicular cell formations and the total number of follicular cells in the aspirate were counted using the ThinPrep® method. RESULTS With the Aspirator 3, the total number and the mean number of extracted cell formations were significantly higher than the values achieved with the manual technique (total: 3222 vs. 1951, p=0.02; mean: 27 vs. 16). The total number of cells that were biopsied was also higher when the Aspirator 3 was utilized (47,480 vs. 23,080, p=0.005). Overall, the Aspirator 3 was superior in 65 biopsies, and the manual technique was superior in 39 biopsies. CONCLUSIONS In terms of cell formations and the total number of cells aspirated, the Aspirator 3 was superior to the manual technique. Further, the Aspirator 3 was more convenient to use and had a greater precision in needle guidance.

Abstract
AIMS To assess whether the large needle aspiration biopsy (LNAB) histological distinction between pure microfollicular nodules and mixed micro-macrofollicular nodules can assist preoperative selection of a Hürthle cell nodule (HCN) discovered by fine needle aspiration cytology (FNAC). METHODS AND RESULTS In 24 HCN identified by preoperative FNAC, preoperative LNAB histology was compared with postoperative pathology. FNAC demonstrated seven benign HCN (negative), eight HCN with atypia (positive); seven suspected cancers with HC (positive); and two cancers with Hürthle cells (positive). LNAB showed mixed micro-macrofollicular hyperplastic features in 12 nodules (negative) and a microfollicular structure in 12 nodules (positive), two of which included findings of papillary cancer. Postoperative findings were benign (negative) in 16 patients and malignant (positive) in eight patients. The sensitivity and specificity for FNAC were 87.5% [seven of eight, 95% confidence interval (CI): 47.3-99.7%) and 37.5% (six of 16, 95% CI: 15.2-64.6%], respectively, and for LNAB were 87.5% (seven of eight, 95% CI: 47.3-99.7%) and 68.8% (11 of 16, 95% CI: 41.3-89.0%), respectively. FNAC results were significantly different from postoperative results (McNemar's test, exact two-sided P=0.012), while LNAB results were not (McNemar's test, exact two-sided P=0.219). CONCLUSIONS These data suggest that LNAB histology is more accurate than FNAC cytology for the preoperative selection of HCN.

Abstract
A general consensus on the role of testicular biopsy in non-obstructive azoospermia (NOA) is needed. This paper reviews and updates technical aspects and clinical performance of the percutaneous testicular biopsy techniques, in particular large-needle aspiration biopsy (LNAB), and proposes a flow chart for the management of NOA. The English literature and original data were reviewed or analyzed. Large-needle biopsy (LNB) includes large-needle cutting biopsy (LNCB) and large-needle aspiration biopsy (LNAB). LNCB usually requires scrotal incision for the insertion of relatively large needles. Fine-needle aspiration biopsy (FNAB) does not require surgical equipment or expertise, employs the smallest needles (23- to 20-gauge), and permits sperm cytologic detection. LNAB also does not require surgical equipment or expertise, employs needles of size from 20- to 18-gauge, is safe, and can be used for testicular histology and sperm recovery. An operative flow chart is proposed for the management of NOA in which FNAB, LNAB and open surgical biopsy are used for the optimal management of NOA.

Abstract
Thyroid nodules are very common lesions. Despite that the great majority is benign, in a significant percentage of them there is an underlying malignancy. Malignant thyroid nodules should be managed surgically, while the more common benign thyroid nodules may be managed conservatively. A systemic and careful diagnostic evaluation is needed to recognize nodules (overtly malignant or with malignant potential), and to avoid unnecessary surgery in a large percentage of patients with benign disease. Fine-needle aspiration (FNA) has a central role in the diagnostic investigation of the patient with thyroid nodules. FNA is a safe, useful, and cost-effective procedure. To increase accuracy, FNA can be performed under ultrasonographic guidance (if needed). Its results may be particularly helpful in determining the indication for surgery. In contrast, the role of FNA in selecting the extent of surgery is limited today. This is due to the fact that during the last decade there is a clear trend toward radical surgical management of thyroid nodular disease (both benign and malignant) by total/near-total thyroidectomy.

Abstract
Galectin-3 (Gal-3), which has received significant recent attention for its utility as a diagnostic marker for thyroid cancer, represents the most well-studied molecular candidate for thyroid cancer diagnosis. Gal-3 is a protein that binds to beta-galactosidase residues on cell surface glycoproteins and has also been identified in the cytoplasmic and nuclear compartment. This marker has been implicated in regulation of normal cellular proliferation and apoptosis, as well as malignant transformation and the metastasis of cancer cells. We here present a mechanistic review of Gal-3 and its role in cancer development and progression. Gal-3 expression studies in thyroid tissue and cytologic tumor specimens and their methodological considerations are also discussed in this article. Despite great variance in their methodology, the majority of immunohistochemical studies found that Gal-3 was differentially expressed in thyroid carcinoma compared with benign and normal thyroid specimens, suggesting that Gal-3 is a good diagnostic marker for thyroid cancer. Recent studies have also demonstrated improved methodological reliability. On the other hand, Gal-3 genomic expression studies have shown inconsistent results for diagnostic utility and are not recommended. Overall, the development of Gal-3 as a diagnostic marker for thyroid cancer represents a promising avenue for future study, and its clinical application could significantly reduce the number of diagnostic thyroid operations performed for cases of indeterminant fine needle aspiration biopsy cytology, and thus positively impact the current management of thyroid nodular disease.

Abstract
BACKGROUND New techniques of improving diagnostic reliability of thyroid nodules are needed. AIM AND METHODS This prospective cohort study includes patients with one (201) or multiple (22) palpable nodule(s). Preoperative fine-needle aspiration biopsy (FNAB), large-needle aspiration biopsy (LNAB), and galectin-3 detection on LNAB (GAL-3-LNAB) (total of 245 nodules) were compared when the FNAB finding was 'inadequate' or 'indeterminate'. The sizes of the needles used for FNAB and LNAB were compared with the size of thyroid follicles. Forty nodules were surgically excised according to current recommendation. RESULTS GAL-3-LNAB was inadequate in 4% of nodules, compared with 34% using FNAB and 11% using LNAB (P < 0.0001). GAL-3-LNAB showed no indeterminate findings, compared with 15% using FNAB and 13% using LNAB (P < 0.0001). Among the 40 excised nodules, GAL-3-LNAB showed the highest accuracy values. The sensitivity (P = 0.011) and specificity (P < 0.000; P = 0.001) ranges were 40%-100% and 20%-40% for FNAB, 40%-100% and 50%-53.7% for LNAB, and 100% and 76.7%-80% for GAL-3-LNAB, respectively. The largest needles used for LNAB, 20 or 18 gauge, with an internal diameter of 0.6 or 0.91 mm, recorded the lowest rate of inadequate or indeterminate FNAB findings. CONCLUSIONS GAL-3-LNAB reduced inadequate, abolished indeterminate findings, and provided specificity values higher than FNAB or LNAB in palpable thyroid nodules.

Abstract
Studies from single institutions report an acceptable accuracy rate for thyroid fine needle aspiration (FNA). However, FNA accuracy is much lower in many other centers in Europe and the USA and large multicenter studies indicate that the clinicians' confidence in the FNA technique remains low. One explanation for this is that there is an excess of inadequate and indeterminate findings for a follicular nodule at FNA cytology. In a University Hospital with large and qualified experience on thyroid nodule diagnosis, a review of 320 slides with an FNA diagnosis of indeterminate follicular nodule from different minor Italian Hospitals led to a different diagnosis in 61%. Since ancillary thyroid imaging may be overutilized and only a few authors report a proportion of excised nodules lower than 10%, we suspect that use of the FNA procedure is suboptimal. Several techniques are reported to improve the performance of thyroid FNA. Among these are tumor markers and large needle aspiration biopsy (LNAB). Immunodetection of the tumor marker galectin-3 has been evaluated by large multinational studies. Analysis of LNAB specimens reduces the number of inadequate FNA findings, improves the diagnostic determination of indeterminate follicular FNA findings and represents a better substrate for the determination of galectin-3. Therefore, we propose that clinical practice guidelines reflect these adjuvant techniques to thyroid FNA in order to improve selection criteria for thyroid nodule surgery.
